Drop down menus on certain websites (ie ESPN) are no longer working on Firefox but work with both Chrome and IE on same computer so I believe its Firefox issue.


I tried updating Firefox to 19 and then even the Beta 20 version. I have rebooted computer countless times. On the same computer, I can open IE and bring up ESPN and the drop down menus work fine so I know its not a computer issue and it must have something to do Firefox. I tried the "starting in safe mode" and disabling add ons because I saw those suggestions but that didnt work. I also tried unchecking the box about hardware acceleration because I saw that suggested also and needless to say that didnt work either. Can someone please please help me, its very frustrating.

The menu on the ESPN site is generated via JavaScript, so make sure that you aren't blocking JavaScript if the menus aren't working.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe mode start window or otherwise make changes.

I am having this exact problem with Firefox 19 on a Windows 8 machine. I did not have the problem with Firefox on a Mac OS X machine.

I have tried all of the above suggestions, with no luck.

Also, I was having this problem in Chrome, but that was fixed from a touch option in the Chrome advanced about options. (I do not have a touch system - it was just a solution I found)

So, my issue is now fixed... I had a 120GB SSD that was almost out of space, and I upgraded to a 256GB SSD today; my issue with Firefox is now gone. Not sure what the issue was, but it is now gone with a HD hardware upgrade.
