Hello. I have a Windows 10 64-bit PC and have been using Mozilla Firefox as my primary internet browser. I have made sure that my Firefox is up-to-date under the Options Menu. I have defragmented and optimized my system. I use Avast anti-virus and Cleanup Premium and have scanned the system for Malware or Viruses. The problem is that Firefox does not seem to be compatible with Windows at all. I get frequent system hangups and stalls with messages displayed across the screen in a yellow bar that reads, "This web page is slowing down your browser". Two choices are given and neither choice ends the hang up: Stop Script or Wait. This doesn't just happen on one website. It happens throughout the day. If I have been using the computer, then leave the house for a few hours and come back, I come back to a completely locked up screen. The system gets slower and slower and slower as it is used throughout the day. Sometimes, my screen turns completely black and wiggling my mouse or hitting a key on the keyboard doesn't wake it up. I have to do the Control-Alt-Delete thing five or six times to wake it back up and Sign Out and Sign Back In. Then, all is back to normal for a while. I have uninstalled and reinstalled Firefox with no improvement. It doesn't seem to happen with other browsers; however, I have always liked the option of keeping my Toolbar at the top of my screen with Bookmarks where I can alphabetize my bookmarked webpages and stick them in alphabetically-arranged folders, etc. You can't organize your bookmarks or favorites as well using other browsers. You get stuck with a non-alphabetical list, stupid stars, etc. I hate all other options. It is MUCH MORE efficient this old way. I would like to keep using Firefox, but this cannot continue. Is there any other advice that you can offer that I have not tried to stop these stalls and hangups?

hi, could you go to the firefox menu ≡ > help ? > troubleshooting information, copy the contents of that page and paste them here into a reply on the forum (or if it's too long through a site like and provide the link here)?

this might give us a clue what is going on. thank you!
