Firefox Settings Across Platforms
My primary machine has (FF 88.0.1 64-bit) has all the FF tweaks for privacy and annoyances I care to have. Last outstanding issue is floating videos -- but that's posted as another topic by me. Big questions:
1. Can I bring FF on the three other laptops and server to the same FF revision level at this machine and copy across all files that would capture settings this machine's settings/changes in Config and Policies ?
I currently make quick work of syncing UBlock and AdBlocker on all machines by simple export/imports of text files. Everything tweaked exactly the same on every machine with respect to FF is what I am after...
You can install whatever version of Firefox you want. But older versions may have problems accessing the web.
You can use sync to share passwords, bookmarks, and history. Anything else may not be compatible between different browser versions or computer systems.

Thank you for your response but password, bookmarks and history are not the instant problem...
I can install the same exact version of FF to all four machines. Then is it possible to copy over all Config and Policies settings to the other machines ?
Yes. Sync can do much of that for you. If there is something else you can use a thumb drive.
