FireFox is not working properly

Posted

Hi, recently I've been constantly getting error messages such as: "URL Is Not Valid and Cannot Be Loaded" . In addition to that, i frequently can't watch video's in YouTube (also says error) and another thing that happens a lot is that pages won't upload (it says "the connection was reset"). I have no problem with my net because i tried to do the same thing in internet explorer and it worked perfectly. What should i do? if i uninstall and then install firefox again, would it help? would it erase all my bookmarks and shortcuts beneath the status bar? thank you for your help! Hadar.

Start Firefox in Troubleshoot Firefox issues using Safe Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

  • Don't make any changes on the Safe mode start window.

See:

If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.

  • Use "Disable all add-ons" on the Troubleshoot Firefox issues using Safe Mode start window to disable all extensions.
  • Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

Question owner

thank you for your help, but it didn't work. i started firefox in safe mode, disabled all plug-ins and add-ons and then i couldn't see anything in youtube (it wanted me to download flash player from adobe). i started to enable add-ons that i had and checked to see if i could watch the video, and nothing worked. i downloaded what it told me and now i can see video's but occasionally it says "an error occurred, please try again later", but it never works. not only that but if it does work, the minute i try to hit the full screen bottom, i get the same message and i have to refresh the page..
