Visual Bee is known as a malware program and is most likely the cause of both issues.
You must remove it from your computer, not just Firefox.
You can also try running a malware check.

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

You can try these free programs to scan for malware, which work with your existing antivirus software:

• Microsoft Safety Scanner
• MalwareBytes' Anti-Malware
• TDSSKiller - AntiRootkit Utility
• Hitman Pro
• ESET Online Scanner

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.

Further information can be found in the Troubleshoot Firefox issues caused by malware article.

Did this fix your problems? Please report back soon.

If your end knows that VisualBee is a problem, Why did you allow it to be a part of an "required upgrade" of Firefox. I was just lucky that my virus program stopped this when it did, although just enough of it caused me several hours of work to fully remove all of the "additional crap" that was downloaded. This is not a way to keep your product users happy campers.

Visual Bee is in no way related with Mozilla.
This is a third party program that is offered with other installs and may update itself automatically.

This program was not installed by Firefox or any other Mozilla products.
Sorry for any inconvenience that this has caused.

I am glad to hear that your problem has been resolved.

If you have not already, please mark this thread as solved by marking the solution.

I hope you continue using our products and thank you for contacting Mozilla Support.
