This very tiny (12KB) add-on which helps to add a “Restart” menu item to
the “File” menu, and a ctrl/cmd + alt + r hotkey to Firefox or
Seamonkey that will restart the program.
FastestFox: This is one of those plugins that can almost do it all. FastestFox allows you to save videos to your hard drive, even if there isn’t a download link. It also allows you to highlight any text on a page and FastestFox will offer a Wikipedia definition and links to various search engines with a query of your selection. All Wikipedia articles are preloaded into a left-column list, and if you choose the search engine, you’ll never have to continually click “next page” — FastestFox autoloads the results so you can scroll forever. It’s seamless and terribly handy. Whether you’re doing research or merely browsing, this add-on makes your life simple.
Vertical Toolbar
Vertical Toolbar is another useful Firefox extension that adds a vertical toolbar at the edge of the window.
Personal Menu
Personal Menu is kind of a next-generation version of the much-loved Tiny Menu, accomplishing the same basic but totally great effect: Giving the web content you're actually looking at more space to breath. It does this by stripping the screen-wide menu bar at the top of Firefox's windows and converting it into a single drop-down menu, then lets you choose which of those menus show up in it. Keyboard shortcut ninjas can enable an option to temporarily bring back the menu bar when Alt is pressed, and the extension auto-adds a history and bookmarks button to the main toolbar to compensate for the two most active menus.ChromaTabs Plus: If you’re interesting in adding a little more color and life to your everyday browsing, then this little plugin can make a big difference. Instead of the usual gray, it gives each browser tab its own color. The color is assigned automatically depending on the color of the site’s favicon, but tabs can also be customized by you and given site-specific colors.
Personas Plus: Here’s another add-on to spice up the look of your favorite browser. After installation, you can choose from over 100,000 browser themes. Selecting a new theme is quick and easy, and provides a refreshing new look and personalization to your online experience.
AutoCopy: For anyone who has to copy and paste any amount of text on a regular basis, this add-on will suit you well. It copys text as soon as you highlight it, without having to right click and select “copy” or doing a Ctrl+C keystroke. It also corrects long, wrap-broken URLs automatically. Three cheers for making a daily task easier!
