I cant seem to install Firefox 50 on my MAC OS Mohave. Also, how do I keep it separate from my current Firefox?

I need an earlier version of Firefox that will support Java. I'm told Firefox version 50 can. I tried to install it but my computer says it cannot install with the Mohave update. Can you help me with this? Also, I would like to keep Firefox 50 separate from my current Firefox which is the latest version and that I use for everyday items. How do I ensure it does not override my current Firefox?

I don't know Macs or Mohave and called for more help.

As far as having more than one version of Firefox;

Download the full installer of the program you want. During the install, switch to manual and select the folder where you want that Firefox placed.

Make sure you have a separate profile for each version because some things, like add-ons and some settings, are not compatible.

You can use sync to share password, bookmarks, and history. Anything else may not be compatible.

The Firefox ESR 52 version for Mac (which still supports Java) you can download from here :

https://ftp.mozilla.org/pub/firefox/releases/52.9.0esr/mac/

I don't know if it's compatible with Mac Mojave, though .....

my current Firefox which is the latest version and that I use for everyday items.

According to you system details you're on version 61.0.1 - the latest (release) version is : 62.0.3 ......

How to run those two versions simultaneously : see FredMcD's post.
