For those times you know there is a tab making noises that won’t let you peacefully listen a track or a movie (thanks Flash and programmers), comes Muter, a Firefox extension developed by Yuan Xulei (袁徐磊), that adds a button to the Add-on bar that you can click to make Firefox quiet.
Unfortunately it doesn’t let you know what tab is playing, it mutes the whole application, so it is really a shortcut to, on Windows, the Sound Mixer and muting Firefox there. Still, a good help for those who hasn’t opted to make Flash an invite-only guest with Flashblock.
Muter will let you customize the hotkey (Ctrl + Alt + M by default), the icon, and the button placement.

You’re reading an article but you need to see as much of it as possible at a time, perhaps for copying or comparing some text to another window.
Instead of manually scrolling the page to find the right spot, you can right-click on wherever you want to scroll to, and select Scroll here, courtesy of Scroll Here, a Firefox extension developed by Alex Henry.
Available at Mozilla Add-ons.
If you need to copy several different pieces of text from several pages to different text boxes, cells or tabs, and spare the repetitive copy/switch/paste, grab MultiCopy, a clever Firefox extension developed by Guruprasad that allows you to copy as many as and as long pieces of text as you want and then paste them sequentially to wherever you can enter text. I tried with about 15 different pieces from several different tabs and it worked perfectly.
To copy the strings use the usual hotkey (Ctrl or Cmd + C) or the selection context menu. You can also take the different pieces to another application but you will get all of them pasted together. Not as handy but still helpful and time saving.

Mobile Barcoder, a Firefox extension, brings you a quick cool way to transfer data and web addresses to your cell phone by just pointing its camera to the screen.
Visit a web page and hover the status bar icon to get a 2D bar code of the current web address. You will need a 2D bar code scanner app in your cell phone. Load it and point your cell phone camera to the 2D code. Your scanner application will convert the code back to the web address which you can now use any way you want.
You can also create a 2D code of any text selection: right click on it and select Create bar code from selection. I was able to transfer between 50 and 60 words in a single code scan using the largest 2D bar code image size.
Mobile Barcoder can produce QR Code or Data Matrix 2D bar codes to suit your application capabilities.
