can 54.0 and 57.0.2 run at the same time?
My PC is getting very slow, & I frequently get the message that Mozilla "is not responding." Depending what I'm doing I sometimes get the message that Firefox is already running, as though there are 2 versions. Well, looking at my app files, I have "Mozilla 54.0 10/7/17" and "Mozilla 57.0.2 12/8/17." Do I have 2 competing versions? The icons are slightly different. Was one to replace the other? I did have 2 different icons for Firefox on my desktop screen for a time. Basically, can I safely remove the 54.0 version, if that's what causing the problem? Will I be losing anything? Thanks!

First, when running different versions of the browser, each should have its own profiles folders because of compatibility issues.
Second. Each version must run in its own separate process. Otherwise, you may get the 'already running' message.
Here is an example of how to run a Firefox separately from any others; Note: All on one line.
C:\PROGRA~1\MOZILL~1\firefox.exe -no-remote -new-instance -new-window -P Firefox_v_57
Firefox Commad Line Options
