All old and new email in Gmail is blank (only when viewed with Firefox on PC). How do I fix it?

I recently switched over to Thunderbird for my email client. I pointed my Gmail to go to Thunderbird. After doing so, I discovered that every single old and new email in Gmail (when trying to view in Firefox) were blank.

Hoping to resolve the issue, I stopped forwarding Gmail to Thunderbird, then I deleted the Gmail account from Thunderbird. Finally I uninstalled Thunderbird and emptied the cache and cookies. Still have blank emails when opened in Firefox. Chrome Edge & IE work fine.

I'd prefer to keep using Firefox over the other browsers.

Thanks for any & all suggestions and help you may have to offer.

Problem solved. It had nothing to do with Firefox! For some reason the ad blocker (uBlock Origin) decided to block everything in Gmail.
