I have been seeing this quite a bit with a website I'm developing for a corporate intranet. The only way to resolve this is to clear the cached web content.

Beyond that, I have no idea what the root cause is. I have disabled some add-ons that I don't need and will monitor.

Thanks for the report. I'm going to duplicate this to Bug 1707979. We think it may be resolved on newer builds (that build 20210527174632 doesn't have the patch)
