I confirm that disabling Firebug fixes the problem. I disabled Firebug, problem fixed. I enabled it again, the problem is still fixed (it's great that we don't have to restart the browser anymore to do that).
I investigated a little. I had Firebug 1.10.6 which I just learnt is only for Firefox up to 18. Unfortunately it never autoupdated. I removed it and downloaded version 1.11.2. I restarted Firefox to be sure to have a clean environment and the problem is still fixed. So it might be a matter of versions incompatibilities. Please check your Firebug versions. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1165058 Title: Long right click menu in Firefox 20 Status in “firefox” package in Ubuntu: Confirmed Bug description: If I right click anywhere in the Firefox window, regardless of the item I click on, a very long menu opens (taller than the screen, it scrolls). It seems to be a concatenation of all the right click menus I used to see up to to this morning with Firefox 19 and previous versions. Unfortunately I cannot take a print screen because the menu closes when I alt-prtscn. These are the first entries of the menu after the separators. Maybe they are useful to track down the menus that compose the aggregate one. Add to dictionary Open Link Bookmark this link Play Reload image Save image as.
