Hi,

You can consider the Reset Firefox feature via Help (Alt + H) > Troubleshooting Information.

(To revert to the previous profile you were using, close the new profile (i.e. exit Firefox), start Firefox and choose the Default User profile. While the Profile Manager is open, you can also delete the newly reset profile (the one containing random numbers), or the former profile, as the case may be). If the reset is okay, it would be a good idea to delete the old profile as otherwise it would be left intact with the previous data until deleted.

Managing profiles

Profiles Howto

If you have security software (antivirus, firewall etc.) installed, you can try deleting all existing instances of Firefox and its related files in all the different configuration areas/modules of the security software like process monitoring, sub/spawned process control, virtualization etc. in addition to the main AV/Firewall module. Instead create new fully allowed/trusted rules for Firefox + its related processes. Even otherwise some security software may also ask again when Firefox is started and you can try to allow/trust at that time. Please see this.

AV/Firewalls Configuration

I can't do this it only displays the page won't let me do anything after that i have tryrd

Please also try to open Firefox in a new profile, or in Safe Mode. If it fails, you can try to adjust the security software. The security software forum would also be helpful. Please also see this.

Start Firefox in Safe Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).

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

You can use one of these to start Firefox in Safe mode:

• Help > Restart with Add-ons Disabled
• On Windows, hold down the Shift key while starting Firefox with a double-click on the Firefox desktop shortcut
• On Mac, hold down the Options key while starting Firefox

Can you launch the profile manager and create a new profile?
