firefox does not start
I had to reload Windows XP. When I reinstalled Firefox 29, I received an error message that the program had a problem starting up and had to be closed. Can you please help me. Thank you, Jeff

Hello, Thank you, but it did not work. It only starts in safe mode. My computer was built for windows 2000. I was able to run version 31 on it till I deleted it when my daughter dump so addons. Jeff
You can try to disable hardware acceleration in Firefox if you can start Firefox in Safe Mode.
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
You need to close and restart Firefox after toggling this setting.

If it works in Safe Mode and in normal mode with all extensions (Firefox/Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit)
Hello, Thank you for the help. My daughter deleted Firefox. I reinstalled it and now it does not start. it did start in safe mode. I have not been able to start it normally, so there are no addons. I have an older computer and xp. I do not meet the requirements but the version 30.0 was working. Jeff
Create a new profile and see if it works.

Hello, How are you? I deleted Firefox 30. I installed version 15, then I installed 31. Now when I start it up I get a different error message. Another copy of Firefox is running and I have to close it or restart XP. What do I do now. Thank You,
Jeff
Restart the computer. When the computer is done booting, try to Start Firefox in Safe Mode {web link} While you are in safe mode;
Type about:preferences in the address bar and press enter
Select Advanced > General. Look for and turn off Use Hardware Acceleration.
Poke around safe web sites. Are there any problems?
Then restart.
