Hi there , I am interested to know if Mozilla support group is aware of the problem Microsoft update KB4474419 causes? I am running widows 7 sp1. I installed the update as you mentioned in your Firefox 100 release notes. After reboot , I got a beep and a black screen - win 7 won't start. I had to find a way to delete the update so I could boot my system back. I asked few of my colleagues that use the same OS and they experienced the exact same problem. Surfing the web , makes it quite clear - this update is faulty and not compatible with win 7 as Microsoft claims. I would like to get a straight answer - can I update my FF99 to FF100 , without the notorious KB4474419 , or , as of FF100 , win7 sp1 is no longer applicable to Firefox ? Thanks. look4

I have installed the newest version. When I go to check about updates in Help / About Thunderbird, I get this message:

115.0.1 (64-bit) Release notes Failed to check for updates.

What does "Failed" mean here. That it will never update automatically? Thank you for any answers

Downloaded Firefox update for Android phone and it closed all my tabs, going to history only shows tabs I have opened since I started trying to solve the problem. I have tried signing in and out, uninstalling and reinstalling the app, syncing to laptop and pulling up history there, no luck. I have tried restoring previous session but it does not give me the option. Please help me get my tabs back!
