Why do you use firefox?

I don't use it because of mobile adblock only. There are multiple private chromium browsers which have mobile adblock, and also one supporting extensions : kiwi browser.

I use Firefox because it's a competing engine to chromium, and it looks good.

I also have all the synced bookmarks from my PC Firefox, which I use for the same reason, and because I got used to it.

I normally don't jump on bandwagons, but this is the way. After using ublock on firefox on my phone, it was an easy decision to switch from chrome to firefox (librewolf) on my computer too (so everything would sync lol)
