Firefox no longer works with any financial institution with which I deal. It is clear it no longer meets their security requirements. I've had to switch to Edge for financial stuff.

Do these websites show a specific error message or warning ?

Are you using any content blocking extensions that could be causing issues ?

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, DuckDuckGo PE, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block content.

Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content. You can click shield icon for more detail and possibly disable the protection. You can check the Web Console for related messages blocked content.


You can create a new profile as a quick test to see if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

I get a 404 error. This problem is recent. It is easier to use a different browser for financial stuff and leave the rest of my browser use on Firefox, with hope that Firefox fixes the problem rather than my having to jump through hoops.

Is that a message coming from Firefox or from the website (i.e. a specific page cannot be found) ?

Can you attach a screenshot?

Do you use a bookmark or are you starting with the main (home) page of this website?

If you use a bookmark to access a specific page then instead navigate to this page starting with the main page or with the sign in page in case there is a problem with this bookmark.


Do these websites use the secure HTTPS protocol or possibly insecure HTTP ?
