Why do I have to clear my browser cache every time I open firefox?
A few months ago Firefox stopped working properly. I think there is something wrong with the Adobe Flash plug in, but I've uninstalled and reinstalled it several times to no avail. Whenever I go to a website that uses flash player, I get an error message that the video can't load and that I should clear my browser cache. Sometimes after clearing it the video will play, sometimes it won't. But every single time I go to the website, I get the same message. Flash works fine on Chrome and Internet Explorer, and I'm about to give up on Firefox altogether.

Check your plugins are updated!
Make sure you enabled cookies in firefox
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.
To Reset Firefox do the following:
- Go to Firefox > Help > Troubleshooting Information.
- Click the "Reset Firefox" button.
- Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
- Firefox will open with all factory defaults applied.
Further information can be found in the Refresh Firefox - reset add-ons and settings article.

The Adobe Flash plugin doesn't even show up in my list of plugins - not sure what to do about that. I know it's on my computer because it works in Chrome and Internet Explorer, but it doesn't work in Firefox.

Resetting firefox didn't change anything. I've tried uninstalling and reinstalling the program and that didn't help either.
Install the flash manually
Make sure your not using any flash block addons/extensions.
Remove unwanted extensions

I installed flash manually and there were no errors, but it still does not appear in my list of plugins and videos will not play.
I'm not using any flash blockers, I have no unwanted extensions, and no malware.
The clean reinstall didn't work either.
The Flash plugin does sow in the system details list added to your first post.
- Shockwave Flash 11.6 r602
You can check for problems with current Flash plugin versions and try these:
- disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
- disable protected mode in Flash 11.3 and later
- disable hardware acceleration in the Flash plugin
Make sure that you aren't blocking cookies and that local storage is enabled, both in Firefox and in the Flash player.
Try to clear the Flash local storage and settings.
- Windows Control Panel > Flash Player > Storage: Local Storage Settings
- Remove a specific domain: Local Storage Settings by site
- Remove all domains: Delete All and Delete Data

Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.
