Mediafire suddenly won't show grid images in Firefox only

[love10001212]

HNY everyone!

After using Mediafire with zero issues for many years, suddenly (as of about 2 months ago) it will not show images when grid layout is selected - just a generic icon they use is displayed. List layout shows the photos fine, in teeny thumbails.

I submitted a ticket 2 months ago, got a few emails with the typical troubleshooting suggestions I'd already done, and a promise that TS would follow up but they never did, even after 2 follow ups

Chrome and Edge display them perfecly fine. No other issues with FF. Cleared everything, restarted in safe mode, and they still dont show.

Any suggestions would be great, thanks!
