I've been using 1PW since v.3. Currently on v.7, and have an account as well as my old license. I'm willing to try out v.8 if others braver than me can report if they have positive experiences with Firefox on a Mac and 1PW8. I've seen several reports of problems, but of course it's generally only the problems that get reported! I certainly want to be able to unlock 1PW with TouchID, as I currently can with the beta extension for 1PW7.
For reference, this will be on a MBA M1,2020, with 16GB RAM and running macOS 12.4 and Firefox 100.0.2.
