I hope someone can help me, as I have yet to discover a solution and am still running 3.6.

Simply put, any time I try running anything over FF3.6, I cannot access "Tools > Options" from the menu bar. Any time I click "Tools" and then drag down to "options" and select it, Firefox immediately freezes and does not thaw. It just stops working, at which point I have to close it via Windows task manager.

I have done the following in terms of trying to resolve this:

1.) Everything.

Everything includes uninstalling and re-installing Firefox, Flash and Java countless times, removing any hint of anything firefox-related from my registry, created and deleted profiles, removed all plug-ins and add-ons, and even jumped down, turned around and gave the dog a bone.

I have no firewall settings or antivirus prevention blocking my ability to access this selection; as I've said, it works beautifully in 3.6 and lower. Above that, I get nothing.

I am sure this is something Windows-related, because something somewhere in my computer is basically saying "do not allow certain actions in Firefox past 3.6." I just can't figure out what it might be.

Any help would be greatly appreciated. However, I must point out this issue is almost certainly going to require a very specific resolution because I literally have tried all the routine go-to fixes many times and none of them have worked. Once I was able to OPEN the options window, but anything I touched in there would again freeze the browser.

I look forward to any suggestions that can be provided.

First, update back to Firefox 17.0.1.

Then, make sure you have fully updated Windows (all service packs, updates, etc.)

Then upgrade your graphics driver. Upgrade your graphics drivers to use hardware acceleration and WebGL

Then try again. If it still happens, try Safe Mode Troubleshoot Firefox issues using Safe Mode

You can check for problems with preferences and try to rename or delete the prefs.js file and possible numbered prefs-##.js files and a possible user.js file to reset all prefs to the default values.

WAIT! Semi-false alarm there.

I was allowed to open tools/windows, but any time I attempted to access the "general" tab, or the file associations tab, the browser would freeze.

It also froze every time I attempted to download a file. For example if I wanted to download a font or other type of file and needed to click on a link to do so, the browser freezes then as well.

I have changed all the applicable settings in my Windows internet options via the windows control panel, and also included the about:config entry "browser.download.manager.skipWinSecurityPolicyChecks," which I set to "true."

Summary: Updating my graphics card allowed me in Tools > Options, but now I cannot download nor access some of the tabs under "Options" in firefox...
