I also experienced similar, but in my case I have my usual aarch64 client with /home on a NFS mount using ff67. What happens is upon occasion mozilla apps (amongst others) from the server direct (using, for example, ssh -Y).
Firefox seems to change the LastOSABI in compatibility to Linux_x64_86-gcc3 from Linux_aarch64-gcc3 whereupon the next time I launch firefox from my habitual client I get the message (like above) > Using an older version of Firefox can corrupt bookmarks and browsing history > already saved to an existing Firefox profile. To protect your > information, create a new profile for this installation of Firefox. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1830096 Title: Firefox 67 in Ubuntu 18.10 thinks it's an older version To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1830096/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
