Can you please try Resetting Firefox and see if that helps? Refresh Firefox - reset add-ons and settings

I have reset Firefox back to it default mode three times. Has no effect on my problem.

is it reproducible every time? can you try to launch firefox in safe mode once and see how it's going there...

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

I have the same problem in safe mode. Nothing will load unless I am constantly moving my cursor.

thanks for reporting back - please try the following:
enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named layers.offmainthreadcomposition.enabled. double-click it and change its value to false and restart the browser.

Followed your instructions. Didn't help. still have the same problem

hey again, we had a similar issue a few versions back, however only a tiny subsection of users were affected by it and developers were never able to reproduce the issue reliably.

in order to have a chance of addressing the issue we would need your assistance in narrowing down the timeframe of when the problem first occurred in the development builds of the browser - this can be done by using the mozregression tool, which will look a bit technical at first sight, but we can guide you through the steps. it shouldn't be that difficult, but will require a bit of time:

• first you'd have to download and install (confirm all setup steps & click close once the process is completed) the the tool from http://ftp.mozilla.org/pub/mozilla.org/mozilla/libraries/win32/MozillaBuildSetup-Latest.exe
• then open windows explorer and navigate to your C:-drive and then the mozilla-build folder. in there you'll find a file named start-l10n.bat - just double-click on that.
• in the black terminal window that opens, type in:
  easy_install mozregression & hit enter
• once this process is finished, enter:
  mozregression --good=2014-04-28 --bad=2014-06-10 --bits=32
  into the same window.
• now the process will automatically download browser builds from the time the error first occurred - just wait until a firefox "nightly" window opens and test if you can reproduce the bug there. then close the browser windows and enter good or bad into the terminal depending on if you got the error this time.
• this process will continue automatically until the exact date is found when the bug was first introduced into the browser - the window will then display a so called regression window and a pushlog. this is the critical piece of information we'd need, so developers can take over and start fixing what's going wrong... please copy and paste this section into the forum here or make a screenshot of it.
• you can then close the terminal window and delete the C:\mozilla-build folder again.

thanks again & please feel free to ask if anything is unclear...

i think the best option at the moment is to use the firefox 31 esr version: https://www.mozilla.org/en-US/firefox/organizations/all/

hey again - another user reported that he could resolve the issue with a scan for malware.would you be able to try it out with firefox 32 again and run a scan with adwcleaner?

Error: Variable must be of type Object. This is what I get when I try and run it.

advcleaner fixed my issue. i can breath now.
