LibreWolf and Betterfox: do they play nice?

[SparkySparkinson]

So, as the title suggests, I'm in the process of moving over to LibreWolf after the recent TOS changes over at Mozilla. I've currently got a modified user.js based off Betterfox, and I've got it in a position where I like how its running.

From what I can see, I can just drag and drop the existing profile folder from Firefox over into LibreWolf without much issues, but I understand that LibreWolf is a fork of FF, so some of the items within the Betterfox user.js would be different and might cause breakages.

I have seen a few threads here and there talking about how LibreWolf is slower when used with fastfox/peskyfox modifications, and something about LibreWolf overrides, so I figured I'd ask it here so that all the most updated information can be consolidated into one thread for other people wondering the same.

In the event that its not possible to replicate Betterfox on LibreWolf, I guess I'll just make do without it. I'm more curious about the experiences of people who might have tried to get it working, and their challenges, to see if I can tackle it at some point in the future.

LibreWolf is slower when used with fastfox/peskyfox modifications

No. In general, LW is slower than FF, unless something has changed since https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/41963. At the very least, it doesn't (didn't?) benchmark well.

There are no conflicts for using Betterfox inside LW.

We previously had a config file just for LW, but I dropped it due to time constraints.

Also, AFAIK, since we disable the main telemetry switch, the TOS changes are immaterial to Betterfox... There's no need to go to a different Firefox fork for those comfortable with a user.js file. Mozilla would have to enable new telemetry prefs every update, or remove the ability to disable invasive telemetry, for me to recommend FF forks.
