    Version 4.1.0

    Released Nov 8, 2026 - 641.44 KB
    Works with firefox 140.0 and later
    Resumable downloads of large files are offered to the save window with the
    file's real name and extension (.zip/.7z/.rar) instead of "<uuid>.txt", and
    a finished file still missing its extension is named after its contents, or
    with one click where the browser requires it.

    Nexus's "Download mod file" window (Manual/Vortex with requirements) gets
    the extension's look, and its "Go premium" banner is hidden with Hide
    Premium upsells on. Nexus's sign-in panel is themed too. Align the relay
    baseline to 4.1.0.

  • Version 4.0.3

    Released Nov 8, 2026 - 632.18 KB
    Works with firefox 140.0 and later
    "Close the extra Nexus tab" closes only a tab opened afresh for the file,
    so a collection's tab no longer closes after a "manual download only"
    first file (issue #45). New setting "Check that Vortex opens" for other
    mod managers that open nxm:// links (discussion #44).

    Browser collections hand the generator's refused Nexus address to the
    browser's own download (diagnostics #7). Requests stopped inside the
    browser and unreadable extension files are named for the person and kept
    out of error reports (#12-#14, #18, #19). Align the relay baseline to 4.0.3.

  • Version 4.0.2

    Released Nov 3, 2026 - 625.16 KB
    Works with firefox 140.0 and later
    Firefox names Nexus's newer files again, "<mod name>-<file id>" with the
    extension their first bytes show, and Import recognizes the files 4.0.0
    and 4.0.1 saved under their uuid (issues #41, #42, #43). Small collection
    files that the browser refused with cookies are asked again without.

    Collections use the Cloudflare fallback: a run Nexus stops for its check
    opens a page for it in a new tab and carries on from the same file.
    Turning the fallback off asks first, and reports say whether it is on.
    The error dialog and collection log quote the notice Nexus shows in place
    of a link. The link wait is at least 15 seconds. Small dialogs wrap in
    narrow windows. Align the relay baseline to 4.0.2.

  • Version 4.0.0

    Released Nov 1, 2026 - 615.44 KB
    Works with firefox 140.0 and later
    Nexus resumable downloads and the large-file question in the extension's look,
    real names for newer Nexus files (folder and .meta included), Vortex links from
    the file page only, a start several seconds sooner, sign-in/file-not-found/
    moderation answers instead of generic errors, and the QA fixes for import,
    collection summaries, large files and archived versions.

    The relay's comparison baseline in wrangler.toml is 4.0.0; the deployed relay
    is updated separately. Extension permissions and reporting choices unchanged.

  • Version 3.3.6

    Released Oct 31, 2026 - 576.08 KB
    Works with firefox 140.0 and later
    3.3.6 — Queue recovery and precise retries
    This patch adds regression coverage for browser recovery, collection summaries and Wabbajack history identity.

    Recovery without duplicate downloads: after a worker restart, an unreadable browser download list no longer means that a pending transfer is absent. The start marker is kept and checked again before another copy can start.
    Restarting after Stop: a successful cancellation callback no longer clears the retirement barrier when the browser cannot confirm the download's resulting state. A readable follow-up can release the wait normally.
    Collection summary retries: files with identical archive names are matched by their queue position and file identity, so Retry and the file-page link refer to the failed file. Reconnected queues do not invent retry targets from ambiguous names.
    Wabbajack history: distinct non-Latin titles sharing a year, and long titles sharing the same prefix, now receive separate history keys. Ordinary ASCII keys are preserved, as are canonically equivalent Unicode spellings. Previously ambiguous titles receive new keys; their existing downloads may need history reimport. Stored history is not deleted or migrated.
    API fallback failures: a router HTTP 403, Cloudflare verification or access-denied response is preserved when the earlier v2 response contains an error instead of usable data.
    Extension permissions and reporting opt-ins are unchanged.

    The live report relay's comparison baseline is 3.3.6. Existing bindings and secrets are preserved.

  • Version 3.3.2

    Released Oct 25, 2026 - 549.74 KB
    Works with firefox 140.0 and later
    v3.3.2 - fix #34, harden ZIP64/MV3/Wabbajack/fingerprinting, optimize logs & mobile UI
    • the folder empty, a full path is never turned into a "D mods" folder
      (single files and collection queues), a finished edit to a full path
      empties the field, and Opera users are told that a folder there means
      the system Downloads folder (13 languages).
    • Collection queues and download state: Nexus outages and timeouts are
      waited out on the same file; a worker restart adopts this extension's
      own started download from the same host instead of a duplicate;
      history imports merge in the worker; a tab can no longer shorten the
      queue's rate-limit wait; small files get their MO2 .meta; reconcile
      keeps going and records failures.
    • Wabbajack and ZIP: entries stream from 1 MiB file slices with an
      incremental CRC (ZIP64 unchanged, now also tested deflated and with
      data descriptors); modlist parsing yields to the page; escaped labels,
      game-name case and non-Latin modlist ids; accurate import summaries.
    • Error reports: frames carry the function, normalized the same for V8
      and SpiderMonkey on the client, relay and dashboard, so one fault from
      any browser is one Discord post and one dashboard issue; top-level
      script frames are kept; NUL no longer gets reports refused; extension
      pages record their own faults; debug lines reach the log again.
    • Narrow screens: the mod picker uses two lines per mod below 560 px,
      report-page controls are 44 px on phones, and dvh heights.
    • Versions 3.3.2 in the manifest, package files and the relay baseline;
      CHANGELOG 3.3.2, release notes and banner.

    Closes #34

  • Version 3.1.9

    Released Oct 20, 2026 - 527.17 KB
    Works with firefox 140.0 and later
    …ay limits (#31)

    From #31, applied on the current main:
    - Collection files get the same name as single-mod downloads: the name in
    the download link when it has a known extension, otherwise
    "<mod name>-<file id>" (NXTK.downloadNameFromUrl in shared.js).
    - New setting WriteMo2Meta (off by default, under Collections): after a
    collection file is saved in the browser, a .meta file with its Nexus mod
    id, file id and version is saved beside it, for Mod Organizer 2. Each
    value is kept to one line, so a line break in a mod's name cannot add a
    key of its own.
    - "Download all mods" (and mandatory / optional) shows a spinner and stays
    disabled until the progress deck opens or the start is refused.
    - Storage reads that feed a write reject on failure instead of returning
    the empty default, so a failed read cannot overwrite settings, history,
    queue jobs or claims.
    - Relay: a shared ceiling of 500 reports an hour for all clients on top of
    10 per IP, and the relay tests check its baseline against the manifest
    version. Needs npx wrangler deploy from relay/.
    - The live Nexus schema check no longer blocks a release; the weekly
    schema-watch.yml still reports problems.
    - Strings in all 13 languages. CHANGELOG lists the unreleased changes and
    credits the contribution.

  • Version 3.1.8

    Released Oct 18, 2026 - 520.42 KB
    Works with firefox 140.0 and later
    Issue #29 (LimeLime875) asks for the collapsed Requirements section on a mod's Description tab
    to start open. New setting "Open the Requirements section" (ExpandRequirements, off by default,
    under Appearance & language, in all 13 languages):
    - Checked on stardewvalley/mods/45538: Nexus's accordion keeps its state in the DOM (dt.accopen,
    dd.open shown) and its toggle listens for a "tap" a scripted click does not make. The section
    is opened the way Nexus opens one it marks expand-default, and a real click closes and reopens
    it as usual.
    - Each section is opened once, so one the user closed stays closed; a re-rendered tab is new.
    The header is found by its analytics hook or by the main-file-requirements it holds.

    Presets: the settings panel saved a preset one setting at a time, so the Browser preset could be
    read, or left if the tab closed, with the new download method and the old "close the tab"
    choice (the Playwright preset test caught it as a race). A preset is now one SETTINGS_PATCH,
    which the background already applies in a single write; a failed write rolls back every setting
    it changed that the user has not changed again since.

  • Version 3.1.7

    Released Oct 17, 2026 - 514.64 KB
    Works with firefox 140.0 and later
    3.1.7 — The right file for Vortex and Mod Organizer 2
    Vortex and Mod Organizer 2 get the link for the file you asked for again, and the reports that reach the maintainer are the ones someone can act on. Both browser ZIPs are under Assets.

    The right file: Nexus's download dialog now names a file by its uid (the game id × 2³² plus the file id). The extension read that uid as the file id, asked Nexus for a file that does not exist, and then refused the correct nxm:// link as another file's: "the nxm link names another file", the most frequent report from 3.1.5 and 3.1.6. Clicks, dialogs, the collection deck and the final Vortex check now read either form.
    Pages fetched as a click loads them: the Vortex page, the requirements page and the download API are requested the way a click requests them, so Nexus answers with the full page and its nxm:// link instead of a tab fragment without one.
    Clearer messages: a collection that Nexus is moderating, has hidden or cannot find says so, in all 13 languages, instead of "Unexpected response · Refresh the page". Closing or leaving a tab mid-request is a cancel, not a network error.
    Reports & privacy — what changed in automatic reports
    Checked locally: ESLint, all 21 regression suites and package checks, 81 Playwright tests in Chromium, and all 12 operations against the live Nexus schema. Firefox package lint reports 0 errors (27 warnings).

    Major update (v3.0.0):
    • Download reliability: Implemented smallest-files-first queue ordering, single-owner click handling, and automatic recovery for interrupted downloads.
    • Official Nexus API integration: Collection and file metadata now use the documented v2 GraphQL API with intelligent caching, request throttling, and HTTP 429 backoff.

    • Responsive UI: Interface now smoothly scales from 720p up to 4K displays and 100–150% browser zoom levels, featuring keyboard-accessible controls and themed scrollbars.
    • Advanced diagnostics: Redesigned bug report workspace with an exact redacted JSON preview, GitHub fallback, and a dedicated live opt-in debug log page.
    • Removed or inaccessible mods are gracefully skipped with clear explanations instead of halting entire collection queues.
    • Updated locale strings across all 13 supported interface languages.

  • Version 2.7.3

    Released Sep 29, 2026 - 314.42 KB
    Works with firefox 140.0 and later
    Cloudflare adds /cdn-cgi/challenge-platform/scripts/jsd/main.js to ordinary
    pages as a passive bot check. cloudflareStrong matched any
    challenge-platform, so a mod page carrying that script in its first 200 KB
    was classified as a challenge. The background collection queue stopped on
    it as a blocking cloudflare verdict, no captcha appeared since there was
    none, and each restart stopped on the same file again (#10).
    • response-classifier.js only takes a challenge's own
      challenge-platform/h/<v>/orchestrate/ path as a marker; the Cf-Mitigated
      header, _cf_chl_opt and the other markers are unchanged.
    • LOAD_BUNDLE no longer records a background error when the page that
      asked was left or reloaded before the bundle arrived ("Frame with ID 0
      was removed").
    • Tests pin the bot-check script on a file page and a signed-in page as
      not a challenge, and use a real challenge path for the strong marker.
    • Bump to 2.7.3: manifest, changelog, README badges and store notes.

  • Version 2.7.2

    Released Sep 27, 2026 - 314.19 KB
    Works with firefox 140.0 and later
    Chromium before 130 parsed a URL of a scheme it did not know as an opaque
    path: nxm://game/mods/1/files/2 had an empty hostname and the pathname
    //game/mods/1/files/2. isSignedNxm took the game from the hostname, so on
    Chrome 119 it refused the signed link Nexus had just generated and every
    Vortex download ended as no_nmm_link (#9).
    • download-url-parser.js splits an nxm:// link by hand instead of through
      URL. The authority must be a bare game domain, which also rules out
      credentials and a port; the path, key, expiry and user checks are unchanged.
    • shared.js reads the game and path the same way for bug reports and for
      validateDownloadTarget's hostname.
    • The Cloudflare recovery advice says to turn off a VPN or proxy when the
      check keeps coming back, in all 13 languages (#8).
    • LegacyChromiumURL stands in for the old parser: the parser cases run
      under it, and nnw-parser-test replays the reported Vortex download.
    • Bump to 2.7.2: manifest, changelog, README badges and store notes.

    • Wabbajack importer enhancements: Supports .zip containers, detects unreadable RAR/7z files, and reads .wabbajack inside archives without full extraction.
    • Activity trail for bug reports: Records recent notable actions; removed DebugLogs setting.
    • Better review links: Now chooses store based on extension ID rather than user agent.
    • Ad-timer cookie refresh: Ensures 'ab' cookie is refreshed during collection runs.

    Works with firefox 140.0 and later
    Major New Features & Changes in Version 2.6.0:
    • Wabbajack Modlist Import (Beta): You can now import .wabbajack files directly! When enabled in settings, a new button lets you read a modlist and queue its Nexus files using the extension's built-in queue system. It fully supports both Vortex and Browser download methods, and gracefully skips/reports external files or unsupported games.
    • Cloudflare Challenge Handling: The background queue now correctly detects Cloudflare verification checks. Instead of failing downloads silently, it pauses the queue and allows you to complete the browser check before resuming.
    • Download Speed Fix: Corrected an issue where bypassing the countdown timer inadvertently flagged users as using an adblocker, which capped download speeds to 1.5MB/s. Free users should now reach the full 3.0MB/s limit.
    • Queue & Performance Optimizations: Massively hardened the collection queue state to prevent it from rolling backwards or freezing. Also heavily optimized page scanning (mod lists and buttons) so the extension uses significantly less CPU on heavy pages.
    • UI & Localization: Streamlined and shortened several settings descriptions across all 13 supported languages for a cleaner look.

    • Support panel now offers GitHub Sponsors, PayPal (@Thomasthanos) and Revolut (@thomas2873) as donation options
    • Vortex handoff now shows a countdown toast with a "Keep open" button before closing the tab, so a failed handoff is still recoverable
    • New "How does it work?" panel in the popup explains the three steps and the sign-in requirement
    • Bug reports now include what the extension was doing (manual click, auto, collection run) and a full session block
    • New Cloudflare fallback toggle in page settings — you can now turn off the automatic tab navigation
    • Fixed: archived file buttons could be attached to the wrong file when the DOM order differed
    • Fixed: navigation poll now runs at 5-second intervals on non-mod pages instead of 1 second everywhere
    • Fixed: Cloudflare fallback now has a deadline and reports an error if the Nexus button never appears
