I’m using Librewolf for everything except for what I need to be logged in. The reason is that Librewolf pretends to be in UTC timezone. This is for privacy reasons, but when I load my calendar I need to see it in my timezone. There are manuals of how to turn that off, but the changes I made following their own workaround (librewolf.net/docs/faq/#what-are-the-most-common-…) never changed that behavior.

So what I do now is using Epiphany for tool sites I need to login and a correct timezone, and everything else I use Librewolf.
