Hi there!

Certain pages show up blank or completely black in Firefox. This occured since after I got a new iMac with the M1 chip.

All pages work fine in Safari and Chrome. and show up completely blank. is visible but does not work as intended.

These pages DO work in Private/Incognito mode.

I have cleared all browsing history and upgraded to Monterey and Firefox 94.0.2.

Make sure you are not blocking content. also see

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?
