Drop-down menu cannot be selected by mouse-clicking

I'm running FF 20.2 on Mac OS X 10.8.3. I recently found that item in drop-down menu cannot be selected by clicking, although it can be selected by hitting "enter" on keyboard. I have no add-ons installed so that shouldn't be the problem. Like go to http://www.newegg.com/ and click search menu, I can't select any options. Thanks for your help in advance.

Thanks ideato for the quick help. Unfortunately turning of the hardware acceleration didn't help with the issue.

If you already checked the safe mode, then try a clean re-install. Certain Firefox problems can be solved by performing a Clean reinstall. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:

Note: You might want to print these steps or view them in another browser.

  1. Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
  2. After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
  3. Delete the Firefox installation folder, which is located in one of these locations, by default:
    • Windows:
      • C:\Program Files\Mozilla Firefox
      • C:\Program Files (x86)\Mozilla Firefox
    • Mac: Delete Firefox from the Applications folder.
    • Linux: If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see Install Firefox on Linux. If you downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
  4. Now, go ahead and reinstall Firefox:
    1. Double-click the downloaded installation file and go through the steps of the installation wizard.
    2. Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

Please report back to see if this helped you!


thank you

I'm having the same issue. Tried reset, reinstall, deleted all addons.

Nothing changed.

Quite a pain. I'm a developer and Firefox is my primary browser...

I did a reset but it didn't help.

For now, I rolled back to version 19 and I'm happy again.

Hope it will be fixed in version 21.

I have this same problem too on FireFox 20.0 on OSX 10.7.5 and none of the above solutions fixed it. This is an extremely critical bug. Select/dropdown lists not working? Really?

It automatically upgraded back to v20 without even asking me... :-(((

I am also having this problem. None of the above tips helped. I have FF version 21.

Another problem I'm having (is it related?) is that I can't minimize or maximize the window.

I also can't click the "x" to close down pop-up windows either.

Any help would be appreciated.
