Hmm. I was one of those who was interested in LibreWolf for long time. Just recently I had to give it a pass for different reason (but for comfort reason as you). Good to read experiences that talk about the “issues” too. I guess LibreWolf could be used for everything that does not require logging in into a website; in example random websites and websearch and so on. But then, maintaining and using two different browsers would be super annoying (for me).

There is also Waterfox, which got some update recently, with version number 6.6.6! I will look into this and how it compares to LibreWolf.
