Hi,

You can try to Reset Firefox via Help (Alt + H) > Troubleshooting Information.

(To revert to the previous profile, close the new profile, start Firefox and choose the *.default profile. While the Profile Manager is open, you can also delete the newly reset profile (the one containing random numbers)).

Which security software (firewall, anti-virus) do you have?

For Avast you can check:

  • Avast -> Additional Protection -> Browser Protection -> under Mozilla Firefox, uncheck the "Run this browser sandboxed" checkbox

You can check the home page setting.

See also:


It is possible that there is a problem with the file(s) that store the extensions registry.

Delete the files extensions.* (e.g. extensions.sqlite, extensions.ini, extensions.cache) and compatibility.ini in the Firefox profile folder to reset the extensions registry.

New files will be created when required.

See "Corrupt extension files":

If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the Tools button at the left side of the Search Bar (or click the "Find Updates" button in older Firefox versions) to check if there is a compatibility update available.

Question owner

I thank you for the reply it was very helpful. I reset Firefox and now it is working perfectly.
