Mozilla and Mozilla Firefox allow users to extend or completely alter existing functionality using extensions (typically small packages/applications). Rather than requiring someone to edit the source, these changes can be loaded like a plug-in, easily disabled or uninstalled. Extensions can be as simple as adding a single menu item or as complicated as completely changing the application interface.
- Combo Tab Icons v0.1.4.3 (Firefox 2.0-3.0.*; screenshot):
- Combines the site and close tab icons. The site icon is only visible when the tab is busy, displaying the throbber.
- Delete Icons v0.1.2 (Firefox 0.9-2.0.0.*):
- Delete site icons via the Tools or bookmarks context menu. (see bug 257791)
- Note: No plans to update for 3.0 at this time.
- Focus Last Selected Tab v0.9.2 (Firefox 1.5-3.0.*):
- Focus the last selected tab when closing.
- Similar to Gorgias' extension (of the same name), but contains only the core functionality and uses a more simplistic and reliable method to determine the last selected tab.
- Open Tab Right v0.3.3.2 (Firefox 1.5-3.0.*):
- Open new tabs to the right.
- Note: Version 0.3+ no longer modifies addTab(), which should cause fewer problems with session-related extensions.
- Plugin Manager v0.1.4.2.2 (Firefox 0.9-3.0.*; for Unix-like systems; screenshot):
- Manage plug-ins via the Tools menu, no restart required. (see bug 19118)
- Background / How it works:
- Firefox can use multiple plug-in paths, which commonly include the installation (/usr/local/firefox/plugins) and a per-user (~/.mozilla/plugins) directories. Since there is currently no interface for (un)loading plug-ins, the next best thing is to simply move the plug-in out of it's respective directory (into a disabled subdirectory) and ask Firefox to rescan for changes.
- Caveats:
- Multi-user systems.
- File ownership and permissions.
- Common issues:
- A greyed out plug-in means the plug-in's parent directory (or it's disabled directory) is not writable by the current user.
- Bugs:
- Windows-unfriendly: plug-ins in the registry are not managed at this time (plugin.scan.plid.all, plugin.scan.*).
- Permission Manager v0.1.1.2 (Firefox 0.9-3.0.*; screenshot):
- Adjusts the content policy settings (allowing image, cookie, script, and related objects) via the Tools menu.
- Popup Blocker Settings v0.2.1.2 (Firefox 0.9-3.0.*; screenshot):
- Quickly toggle between three different modes of popup-blocking - Open all, Block unrequested, and Block all.
- Adjusts dom.disable_open_during_load, dom.popup_allowed_events, and privacy.popups.disable_from_plugins.
- Restore Scroll Position v0.4 - current stable release, but not recommended (Firefox 0.9-2.0.0.*):
- Restore Scroll Position v0.5.9.10 *BETA* (Firefox 2.0-3.0.*):
- Restore scroll position for pages with no-cache and related headers. (see bug 215405)
- News:
- * 0.5+ can restore text inputs if restorescrollposition.formData is true (default: false).
- * 0.5.9+ uses a history event listener for better integration and more reliable operation (mouse nav should work).
- * 0.5.9.9 has gone back to using the 'load' event and will no longer process page loads from Gecko's bfcache.
- * 0.5.9.10 removes the .reload pref (unused since 0.5.9.3), but will continue to restore on reload.
