Hello.

It's possible that you are having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?

Whenever you have a problem with Firefox, whatever it is, you should make sure it's not caused by one (or more than one) of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in safe mode (don't forget to select Disable all add-ons when you start safe mode). If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See this article for information about troubleshooting extensions and themes and this one for plugins.

If you need support for one of your add-ons, you'll have to contact its author.

If the problem is not disappears when all add-ons are disabled, please tell me, so we can work from there. Please have no fear of following my instructions to the line, as all can be easily undone.

Hello,

I had this problem too. It seems to be a request since Firefox 3.5. You must have focus on tabs bar in order the shortcuts [Ctrl][Left] and [Ctrl][Right] work. You can read information about that here: https://bugzilla.mozilla.org/show_bug.cgi?id=462289

I made a small plugin to provide new shortcuts to move tabs: https://addons.mozilla.org/en-US/firefox/addon/220875/

hi, Same problem today in firefox 12. For me the problem come from torbutton addon that keeps me drag and drop , the movement of the tabs, the customizations... Solution, disable torbutton while waiting for an update.
