I was used to press Control+1, Control+2 and so on to switch between tabs in Firefox. Now, in Unity, I have to use the Alt key instead. How can I change that?

There is a nice add-on you can try called KeyConfig available from here. Unfortunately the author hasn't added this to the official Mozilla Addons.

If you still want to try this "untrusted" add-on, click on the keyconfig.xpi and install it. Then go to your firefox addons to display various keybindings offered by the addon

enter image description here

Click on the box shown by the arrow and choose your key combination - CTRL + 1.

This will change the value in the box to CTRL+1. Click the Apply button

Repeat for the rest of the "key_selectTab" values.

Thank you very much. It works great! – Chuqui Jun 19 '11 at 0:13

I've added support for this to my Windows Shortcuts extension (version 0.2).

It's a trival extension with no options.

It sets these shortcuts:

  • Ctrl+J = Downloads
  • Ctrl+E = Search
  • Ctrl+number = Switch to tab number (e.g. Ctrl+1 = switch to first tab)

Hey @Mikel, I was actually looking to do the exact opposite of what your extension does (use ALT+# to change tabs on Windows). I replaced the "accel" key with "alt" key in your extension and installed it locally. Please let me know if you would like me to send it to you so that you can release it as a separate addon, or if you would like me to do so. Thank you. – Mo2 Apr 14 '15 at 16:59

It's easy to change manually:

You can also search for addons that may do it more easy, but changing the accelKey number in about:config is not that hard.

Welcome to Ask Ubuntu! Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. – Eric Carvalho Oct 16 '13 at 14:57
link only answer, but props for going to the source and actually showing why this difference exists, not just other clumsy ways around it. i feel enlightened - after being irritated for months by the lack of ctrl-#, then finding alt-# but not seeing any reason for the difference until now. thanks! – underscore_d Nov 8 '15 at 23:59

Going off of @Aron's answer, simply perform the following steps:

  1. Go to about:config in the URL bar
  2. Search for accelKey
  3. Change the value to 17 for CTRL or 18 for ALT
  4. Restart Firefox
