Firefox 技術支援討論區

I have several machines on my local network. I work on machine A, and run applications remotely using ssh -X on the other machines. Today I discovered that when I start Firefox on newly-upgraded machine B, it's actually starting the older version that's on machine A. This seems obviously wrong, and is certainly not what I want to happen. I want to run the newer Firefox that's on B, and have it display on A.

Longer details: A runs OpenSUSE Leap 15.0. B runs Leap 15.4. I start an xterm on B with the command " "ssh -X -l me B", and programs other than Firefox I run from that xterm display on A's monitors, as expected. However, when I try to run Firefox (by typing "firefox &" on the command line, what actually runs is the older version of Firefox that is on A, just as if I'd started it with the same command on one of A's terminals.

Is this a known behavior, and if so, is there a way to work around it? Or am I just doing something really stupid?

my version of firefox is obsolete in security...so as many sites tell me. I want to upgrade to the newest release but am not sure what happens to my stored logins and passwords. Also, is there any way I can view the stored info...since I have been careless and not saved all of that info.
