I have Windows 7, and when I installed Firefox, almost every time I use a drop-down menu, the menu will display for a split second, but will not stay up. Drop-down menus work fine in IE, but not in Firefox. I have to use the directional arrows to select from the list of choices, and this is problematic with menus with many choices. This happens every time I use a drop-down menu, so the problem is not site- specific.
Could be a conflict with one or more of your add-ons. Not enough information supplied to diagnose possible causes. Try the following:
Firefox Safe Mode You may need to use Troubleshoot Firefox issues using Safe Mode (click on "Safe Mode" and read) to localize the problem. Firefox Safe Mode is a diagnostic mode that disables Extensions and some other features of Firefox. If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes before starting Safe Mode. When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode". Test to see if the problem you are experiencing is corrected.
See: Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems Troubleshoot and diagnose Firefox problems
If the problem does not occur in Safe-mode then disable all of your Extensions and Plug-ins and then try to find which is causing it by enabling one at a time until the problem reappears. You MUST close and restart Firefox after EACH change via File > Restart Firefox (on Mac: Firefox > Quit). You can use "Disable all add-ons" on the Safe mode start window.
i had the same problem, nearly drove me insane!! go to 'basic troubleshooting' and follow the steps to 'reset preferences'. this worked for me although i also ran several antivirus scans.
No dropdown menu in FF will display for more than a milisecond, eliminating me from using many websites with options that must be selected via dropdown menus. Any advice for we novices??
It looks like this can be temporarily fixed by disabling hardware acceleration or possibly permanently fixed by updating one's graphics driver: see this thread for more details.
Does any one remember when you wold suddenly get a registry report that would tell you that it could fix all your registry errors. Suddenly I realised that it was sitting on my programs file. as this was unwanted I deleted it from my add/ remove programs via control panel. Very soon after deleting this unwanted intruding program I noted that I could no longer access my dropdown menu of any kind when I use firefox browser. I have used firefox browser for more than 6 years. This is the only thing that I recall that has caused me to ponder.. Sorry I do not recall the soft ware name however I have experienced this intruding message about my registry from old and new computers. I am thoroughly sure that that this is pay back for not subscribing to offer to clean my registrry??? Think about it ..Could this have happened to you?.. I am forced to use internet explorer as drop down menu works fine.. i just prefer firefox if the drop down menu would work again. K.
I have same issue I'm on Mac running OsX 10.5 Leopard Updated and installed newest version of Firefox 4. I have disabled all plugins and using default theme that comes installed. I disabled hardware acceleration, I tried re-starting in safe mode etc. Nothing fixed it.
Its obviously a horrible Firefox 4 bug not something on my end only. Please fix soon. I like FF, but I will stop using it forever if you cant use drop menus or forms, thats a very basic standard part of web browsing. I would rather that it worked well doing the basics before you try to add too many new features guys!
Currently my best advice to fix this issue is use another browser until FF provides an update.
Is this an interface bug?
On a clean install of Firefox 4 I had the same problem, however holding down the mouse button and dragging to the option I want works fine.
It is just when using the click and release method that the drop down disappears, this is a different behavior from older versions of Firefox where the drop down would stay shown.
