The Open link in… add-on for Firefox adds context menu items for opening links and images in a new background tab (or foreground tab if your tabs normally open in the background), in a new background or foreground window, and in the current tab. Optionally gathers items into a submenu.
New Tab Tools will help you customize the new tab page. You can add more tiles, the launcher from Firefox start, or a background image. You can also set new tile images and other options (as you see in the picture above). This add-on really makes the new tab page a real feature rather than something that I get no use in at all. Want to pick it up? You can find the New Tab Tools add-on from the Firefox Add-ons website.
The Window and Tab Limiter add-on for Firefox will automatically close old windows and tabs. This is so you don’t end up with too many windows or tabs opened up at the same time. This will save you a lot of CPU resources. You can also password protect the add-on so nobody messes with your settings.
This add-on is a lightweight add-on that tells YouTube to load the video in HD straight away. Unlike other add-ons like it, YouTube HD causes no stall in the loading, no refresh of the page and does not manipulate the video object.
The TrustMyWeb add-on can help you to have a safe Internet browsing attitude by checking the status in your Firefox status bar. Without disturbing your Internet browsing, just check if the bullet in your status bar is green and go on!
