Currently I still use Chrome on desktop mainly because Firefox doesn't support having two dictionaries active
at the same time. I switch between writing in Spanish and English so SO frequently that the idea of manually having to switch the dictionary each time makes my head hurt. When they implement this, I may switch.
On Android I do use Firefox because I can have uBlock Origin. I just can't handle ads on mobile, ugh, all these sites in where after each paragraph there's an ad that takes twice as much time to scroll through than said paragraph, the whole page jumping because the ads load late, I just can't. On Android I don't have the spellcheck problem because it's handled by the keyboard but I do miss a feature from Chrome mobile: Being able to automatically open certain links on an external app. For example Reddit and YouTube links. Sure, you can hold the link and choose to open it there manually, but that's annoying, and sometimes it isn't possible because of redirects. For example, you can't do this in a Google result that is a Reddit link, because the URL doesn't point to Reddit, it redirects you later, so you're stuck opening it in the browser. I really really want them to handle this just like Chrome does. For now I installed
this app but having to do the sharing stuff is annoying too.
Brave ALMOST is the best of both worlds, but it isn't, because the adblocking is lame: it doesn't have cosmetic filters, meaning that you end up with an empty space in where ads would be, negating the whole point, I still have to scroll as if the annoying ad was there when reading articles and such.
