Experimental Features

thanks for reporting back! can you try to replicate this behaviour when you launch firefox in safe mode once, in order to test if one of your addons might be interfering here...

Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

the "Move Media Player" entry is probably malicious, so you might want to run a scan with different free security tools specialised on adware and browser hijackers like the free version of malwarebytes and adwcleaner...

i disabled all extensions and it solved the problem. Now to figure out which add on is the culprit, see if there is an update or not. Thanks for being there.

Possible culprits: 1st guess is Tab Utilities 2nd is Norton Toolbar

Tab utilities was the culprit. Thanks so much all ~
