Twitter pinned tab keeps unpinning

I have 5 pinned tabs lately, and many unpinned (20-100s). Recently one of the pinned tabs, Twitter specifically, has been unpinning itself at random(?) intervals. I can re-pin it just fine, it's just a little odd. None of the others do this.

I am running with Tree Style Tabs and per-site Containers (but not Twitter or FB specific container extensions). And other extensions like ABP and NS, but I doubt they relate, while these might?

FF developer edition 83b10 64 bit, on Win10

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window
