After having playing around with extensions for some while, here’s my list of extensions I consider “huge usability improvers”:
- DictionarySearch: Looks up selected word in an online dictionary by context menu. Hint: You can add custom dictionaries, e.g. “http://dict.leo.org/?search=$”.
- Diggler: Adds a button next to the location bar that can clear the location bar (much like the one in Konqueror) and also drop down a menu with more actions.
- Download Manager Tweak: A modification of the Firefox download manager that changes its appearance and allows it to be opened in a separate window, a new tab, or the sidebar.
- Googlebar: An unofficial Google toolbar for Firefox. Note: There is also GooglebarL10N, which gives you localized version.
- LiveHTTPHeaders: View HTTP headers of a page and while browsing.
- Mouse Gestures: Allows you to execute common commands using mouse gestures.
- ReloadEvery: Reloads webpages every so many seconds or minutes.
- SuperScroll: Override the default keyscroll and mousewheel settings.
- Tabbrowser Extensions: Improves tabbed browsing a lot. Note: This extensions seems to seriously slow-down Firefox.
- Web Search Plus: Uses the current Search Bar engine for context-menu Web Searches.
These two come pre-installed with Firefox:
- Web Developer: Adds a menu and a toolbar with various web developer tools.
- Dom Inspector: You’ll need to enable this when you install Firefox – choose the ‘Custom install’ and check the box for ‘Developer tools’. The DOM inspector allows you to view the ‘Document Object Model’ for a web page. See here for more information. Also note that the extension manager of Firefox 0.9.2 seems to have a problem with it (search Google).
Note: This list of extensions is an update of my earlier posting A look at Web Browsers and File Managers.
