It downloaded and installed new version 126.96.36.199. When I started the new version it asked me to enter my master password so it could get mail. I entered my old password and it would not recognize it. Tis happened repeatedly. The only way I could solve this was to load a saved version of my profile (the chrome and extensions directories). Same thing happened on upgrading to Firefox 188.8.131.52. That time I installed a saved profile. Reproducible: Always Steps to Reproduce: 1. 2. 3.
Have you had this problem with upgrades since then? It sounds like something might have gotten corrupted in your profile if so, since it doesn't sound like it's a common problem.
No response, so resolving as worksforme.
