Are you using any theme in firefox?

Please create a screenshot of the problem you're seeing by following the guide mentioned at How do I create a screenshot of my problem?.

Once you've done this, attach the saved screenshot file to your forum post by clicking the Browse... button below the Post your reply box. This will help us to visualize the problem.

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.

Try to disable hardware acceleration in Firefox.

cor-el: I did what you told me, and so far it's working. I may have to wait and keep trying, but thank you. I certainly got fast answers from you. I've asked this question for weeks on Yahoo Answers and got nothing. So thank you again, even if its temporary. I will save your answers and use them again if needed.

iamjayakumars: Thank you. I tried your answer and co-el's and it worked. Sorry, I did both so can't say for sure which worked, but hey, maybe together it made sure. So far its working. Because by now with my typing it would be blurred. I'm saving your answers if needed in the future. Like I told cor-el, your answers were quick. I waited weeks on Yahoo Answers and received nothing. Thanks again. Ferngully2

You're welcome.

Note that running Firefox in Safe mode disables hardware acceleration, so you would avoid extra troubleshooting steps to come to disabling hardware acceleration by changing it directly.

Thank you again. Yes, I did the safe mode first, then I closed Firefox, waited a few minutes. and followed your instructions on the hardware acceleration. I'm no longer in safe mode, and its working ok so far. That could be the solution. Thank you again.
