Firefox loads for approx. a week then stops working and has to be downloaded again

Posted

For the past month or so when I try to get into Firefox it will not load. I will download Firefox and it will work for a few days and then stop working again and I have to re-download again. If this doesn't stop I will try another web browser.

Are you using cleanup or security software that runs once a week that could be causing this?

A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.
