MSFX

Partially opinionated fork of the MSFX Firefox userChrome for non-ESR versions.

Changes

• Uses normal firefox-scripts instead of a stripped down version for greater userscript compatibility
  • Fixed up for 117+ and now bundled with again, as the upstream repo's maintainer is MIA.
• More accurate styles in some places
  • Bookmarks bar folder menus
  • All tabs button
    • Replaced with overflow arrows icon
  • Scrollbars forced to light theme
  • Selected address bar forced to light theme
  • Resize grabber no longer appears when maximized
  • Autoplay Pending indicator icon replaced
  • Accurate menus (117+)
  • Unlocked toolbar style has proper bottom resizer (visual only)
  • Properly styled address bar dropdown
  • Proper hover/active states for menu bar items
  • Scrollbar dithering
  • Sidebar
    • Correct close button positioning
    • Support for "Move sidebar to right"
• Internet status bar widget is its own component
  • Empty boxes have been removed in favor of putting extensions on the status bar
• Address bar is no longer forced to the Address toolbar (configurable, enabled by default)
• Works with Firefox 117+ (fixes developed for on 122.0b3)
  • A lot of legacy styling was removed to where the appearance property does nothing, everything that used this to achieve the classic style has been accurately recreated as best as possible.
• Find bar text entry visibility fixes
• Polyfill for missing legacy colors for scrollbars and grabber (125+)
• Optional polyfill for missing legacy colors everywhere (useful for extensions, see addons folder) (125+)

What's missing?

• The stock extensions menu, the main menu and the overflow tabs menu are not styled, as I do not personally use them.
• More configuration options probably. There might've been some things I commented out for my own liking that you may not agree with in terms of accuracy to IE5.
• Default favicons for bookmark items, as these cannot be changed in pure CSS. (needs investigation)
• Extension button tooltips don't seem to be standard tooltips.

Known issues

• Opening "Customize Toolbar" resets the access key for the Favorites (bookmarks) menu item back to "B", resulting in "Favorites (B)"

What can be improved?

• Stop using base64 URLs everywhere.
• More configuration.
• Nested rulesets, since Firefox itself uses them everywhere. (117+)
  • Some of the 117+ fixes have been using them (e.g. context menus)
• Multiple files.

Installation

• Set the following keys in about:config:
  • toolkit.legacyUserProfileCustomizations.stylesheets to true
  • svg.context-properties.content.enabled to true
  • ui.prefersReducedMotion to 1
  • browser.display.windows.non_native_menus to 0 (removed in 117+)
• Copy the contents of ffroot into your Firefox install folder (typically C:\Program Files\Mozilla Firefox)
  • There is an extra set of folders added (browser\chrome\icons\default) to change the main window icon. The default is the IE5 page icon, but the 2001-2003 Mozilla icon is included as well, just needs to be renamed from _main-window.ico to main-window.ico.
• Merge chrome folder from the repo into your profile's chrome folder. (path can be found via about:profiles or about:support)

Recommendations

• Extensions Options Menu
  • More lightweight than the stock extensions menu, which is "hidden" by the theme anyways
• userChromeJS Manager
