I'll hopefully investigate more in a few days.
My reaction upon reading this is that perhaps you should change your priorities slightly. The fact that the system "works" is a high bar for upgrading, and takes no account of whether the system has vulnrabilities ripe for exploit. OTOH the bank's website may well be checking your version number against the latest available from mozilla (87 AIUI), without regard for any patching done by Debian. FWIW all the sites that I normally visit are working with 78.9.0esr-1~deb10u1, the current version. (Note that writing "version 78.9" doesn't tell us which version you're running—I see a different one in bullseye: 78.9.0esr-1.) Perhaps your problem lies with the mix of packages you have installed, as you wrote "mostly Debian testing" above. But I would repeat Linux-Fan's exhortation not to upgrade FF while an instance is running, and also suggest testing the new version with a fresh profile to avoid losing any information from your old profile. Cheers, David.
