Firefox has a blackbox on the righthand corner. I have tried the fixes outlined for Windows 7 users to get rid of it but nothing works. Any other ideas?
I have the most recent version of Firefox and updated version of Adobe and Shockwave. I tried changing the Shockwave file, refreshing Firefox, disabling the add ons. I would welcome any other ideas for getting rid of the blackbox. Thank you.

Can you attach a screenshot?

Did you try to run Firefox in Safe Mode and possibly disable all the plugins?
Try to set plugins to "Ask to Activate" on the "Firefox/Tools > Add-ons > Plugins" page
In Firefox Safe mode these changes are effective:
- all extensions are disabled (about:addons)
- default theme is used (no persona)
- userChrome.css and userContent.css are ignored (chrome folder in profile folder)
- default toolbar layout is used
- JavaScript JIT compilers are disabled
- hardware acceleration is disabled (Options > Advanced > General)
- plugins are not affected
- preferences are not affected
Create a new profile as a test to check if your current profile is causing the problem.
See "Creating a profile":
- https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
- http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
I see that my reply is marked as unhelpful.
Did you try a new profile folder?
If a new profile doesn't work then try a clean reinstall and do a malware scan.
Do a clean reinstall and delete the Firefox program folder before (re)installing a fresh copy of the current Firefox release.
- Download the Firefox installer and save the file to the desktop
https://www.mozilla.org/en-US/firefox/all/
If possible uninstall your current Firefox version to cleanup the Windows registry and settings in security software.
- Do NOT remove "personal data" when you uninstall your current Firefox version, because this will remove all profile folders and you lose personal data like bookmarks and passwords including data in profiles created by other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
- (32 bit Windows) "C:\Program Files\Mozilla Firefox\"
- (64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
- It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
- http://kb.mozillazine.org/Uninstalling_Firefox
Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure NOT to remove personal data when you uninstall Firefox as that will remove all Firefox profile folders and you lose your personal data.
If you keep having problems then also create a new profile.
Do a malware check with several malware scanning programs on the Windows computer. Please scan with all programs because each program detects different malware. All these programs have free versions.
Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.

I completed a new profile and did a clean re install but I still have the problem. I have Symantic antivirus and I suspect some interaction there. Is there anyone aware of a problem with Symantic?
