Unable to load after latest FF update

I have been attempting to load the pogo homepage several times a day for nearly a week with firefox. I've done all of the usual troubleshooting:

cleared history/cache

restarted browser

restarted wifi

restarted computer

browser is up to date

attempted Edge, but not Chrome (which worked well, but I'd rather not use any other browser than FF.)

There was an update released May 24 and there are some repairs, but nothing that affects this site.

I can't seem to find any resolution within firefox support only update information, but that's really not a surprise.

unable to find a way to to uninstall the update to attempt before/after validiity.

any direction would be appreciated.
