Right mouse button no longer works in Firefox. Still works elsewhere.

[Marianne Wade]

What I expected to happen:
Today I installed all the suggested and recommended updates for Ubuntu, as I always do when updates pop up. After the updates, while still logged into Firefox, my right mouse button worked fine! But I did get the notice on each open Firefox tab that my browser needed to be restarted to complet updates. So I closed out of Firefox. When I reopened it, I went about my usual activities expecting full function of mouse and keyboard in Firefox as I have always enjoyed.

What did happen:
First activity after opening Firefox was to check email. I logged into Google. On my first 'reply' email, I went to "Select All" which is usually available on a drop-down menu I receive when right clicking within the field. This time no menu. I instead highlited the entire text myself then used the keyboard to delete it. Similarly, when I wanted to copy text and use on Facebook, I had to highlight it on one tab holding down left mouse and using Ctrl+C, then pasted it into Facebook using Ctrl+V. When I wanted to save a pic to my harddrive, I again went to right click to first isolate the image on its own but again, no drop-down menu when I right clicked. I tried looking on forums about right mouse not working on updated Firefox and found only older posts that didn't apply. I've logged on and off Firefox a few times and problem still exists.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Sasa Paporovic (melchiaros)]

Have observed this also since firefox13(beta) was in quantal.

Also affects firefox 14(beta) in quantal.

[Nosehair (sbi-gaijin)]

Similar symptoms on a laptop running Ubuntu 11.04 (GNU/Linux 2.6.38-15-generic i686). The left mousepad button no longer pulls down menus in Firefox, making it virtually unusable.

[Nosehair (sbi-gaijin)]

Additional - The URL autocompletion function (ie:- type "goo" into the address bar and get "google.com" , "goo-net.com" and the like presented in an autocompltion, pop-down menu) no longer works.
