Latest version
Version 3.0
Released Aug 21, 2026 - 46.32 KBWorks with firefox 109.0 and laterVersion 3.0 — Major reliability fix
The extension now reads your conversation directly instead of scraping the rendered page. This fixes a set of problems that could quietly damage exports.
Fixed- Missing messages — your own messages could be absent entirely, and an export could contain only part of the conversation while still reporting success
- Duplicated content — thinking text, artifacts and sources appeared twice
- Page furniture in the text — "Thought for 1m 13s", "Claude responded: ...", "7 hours ago", copy buttons
- Paragraph spacing — two blank lines between paragraphs instead of one
- Heading levels — content headings were pushed too deep and lost their hierarchy
- Timestamps appeared twice, and stayed in the text even when the option was switched off
- Options that did nothing — the toggles only controlled whether a section was appended, not what was in the text
- Web search sources exported without their full URLs
- Inline citations were missing entirely
New- Inline citation markers placed exactly where they belong in the sentence, with a numbered reference list per message
- Artifacts exported with their full contents and correct syntax highlighting
- Uploaded images exported by name and link
- Document attachments listed by filename and size
- Honest fallback — if the direct read fails, the export is marked as a fallback and you are told it may be incomplete
Also- No scrolling. Exports finish in a second or two, regardless of how long the conversation is.
- No new permissions required.

Released Mar 19, 2026 - 42.5 KBWorks with firefox 109.0 and laterVersion 2.5.1
Bug Fix
Fixed a bug where a single Claude response was split into multiple separate messages in the exported file. Tables, code blocks, lists, and other formatted content were lost in the process. Exports now correctly capture each response as one complete message with all its content intact.
