It takes 2 minutes and the instructions are very clear. Should not be a problem.

This is the first time I've heard of Lepton. Now I've installed it I don't think I will go back. Thanks!

I don't care about the tabs being buttons though. Mainly the huge amount of space the new design uses. And the lack of icons.

Do you know how lepton would interact with the various firefox css themes (like those on the r/firefoxcss subreddit)? Some of them look really good but I'd imagine there might be conflicts and resulting instabilities. Btw thanks for posting this, I remember using lepton a long time back, I need to switch from edge soon haha
