Hello,

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:

1. Go to Firefox > Help > Troubleshooting Information.
2. Click the "Reset Firefox" button.
3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
4. Firefox will open with all factory defaults applied.

Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Did this fix your problems? Please report back to us!

Thank you.

I tried that as it was recommended on another site. It did not solve the issue...

Hello,

Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.

(If you're not using it, switch to the Default theme.)

• You can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
• Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

Once you get the pop-up, just select "'Start in Safe Mode"

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for that.

To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.

Thank you.

Hello tuatha, try to install the latest flash : http://get.adobe.com/flashplayer/

and then disable hardware acceleration in Flash , see more info :

Playing Flash videos makes Firefox hang, then check firefox again, if the problem exist then Turn off Firefox hardware acceleration also.

the java Deployment Toolkit, it is not necessary to activate it, blocking the Java DT plug-in does not mean the Java plug-in is blocked, see : What is the Java Deployment Toolkit?, more useful it is for developers.

thank you

Safe mode does not work. Updated to the flash above and it freezes even more - solid crap out. Safe mode too, craps out...

In safe mode I am getting script error pop ups...

I can't even load a damn page in FF currently to change the hardware acceleration... this is getting irritating...

are you getting Warning Unresponsive script - What it means and how to fix it  ?

Yes. However, I was not getting them prior to the update. I don't want to get rid of scripts as most sites use scripts these days. I have no issues with IE...

tuatha, check the above document.

The combination of a recent Windows update and the Flash player plugin's protected mode caused pages to hang for me with the eventual script error.

• You can disable protected mode following the steps in this support article from Adobe under the heading "Last Resort": Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?

• My thread: Flash hangs Firefox (eventually get script continue/stop dialog)

I think it is a microsoft update, i get no errors running on linux, so it must be some (once again) update messing with Firefox Flash.

jscher2000 - you the man! Thank you. That was it!!!
