Rewrite Tabby into a modular extension with settings, top sites, and branding
- Split the single newtab.js into per-feature ES modules (theme, clock,
search, bookmarks, background, branding, top sites, privacy, backup,
settings panel), loaded natively via <script type="module"> — no
bundler, no build step.
- Add an in-page settings panel (gear icon) covering theme + a
configurable accent color, clock format, branding (custom name/logo),
background (solid/gradient/image), an opt-in Top Sites widget, a
Home-page copy-link, privacy details, and JSON export/import of every
setting.
- Make topSites an optional, runtime-requested permission — only
prompted if the widget is enabled, never at install.
- Replace live favicon fetches with locally-generated colored-initial
icons for bookmarks, and Firefox's own locally-cached topSites icons —
no network request is ever made just to fetch an icon.
- Rebrand the default icon/logo away from personal initials so the
extension can be white-labeled; move the privacy card to a discreet
footer note with full detail in Settings.
- Bump manifest version to 1.0.0 and drop an unused icon.png ahead of
first deployment.
