Not to call you out specifically, but I don't understand this sentiment.
How can you "not get into" Firefox?
I don't like the way it looks (And yes I can concede that most browsers these days have a very similar overall design). I still have it installed in case that ever changes, but not likely.
It's not that it is bad, I am very used to Edge (I was an avid Chrome only user for YEARS before switching to Edge), so tiny little changes just make not appealing to me.
For example, even on THIS site, I do not like the default color settings for Dark Mode. In Edge, my address bar, bookmarks bar, menus, right click menus, and tab are all dark. But on FireFox they are not. I'm sure that can be tweaked, but I can't be bothered.
Some subtle little stylized difference on my commonly visited websites as well.
Like I said, just me, not the software per say. Subjective opinion, but again, just can't get into it to keep using it :)
