It will pop up with a notification that says "firefox has stopped working" and my only option is to close firefox I don't believe your stated solution will help since I've recently wiped the computer and got a fresh new firefox, I didn't update it, and it can access the internet, is just crashes randomly?

It could be a problem with the new version.

Do you have nvidia's network access manager or forceware network manager software installed? Disable / remove it.

Try to disable Skype Click to Call.

Start Firefox in Safe Mode to check if one of the extensions (Firefox menu button/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

• Switch to the DEFAULT theme: Firefox menu button/Tools > Add-ons > Appearance
• Do NOT click the Reset button on the Safe Mode start window
