Hello community, As soon as firefox 106.0.2 finished installing itself i was greated with some nice new color schemes to choose from, and also some other settings regarding accessing content and tabs from other devices, retrieving closed tabs and so on. Ever since i can't seem to find and access those settings. Any ideas would be much appreciated. Thanks in advance. I'm on linux, Manjaro.
