This is it. Trying multiple browsers in parallel isn't nearly the pita that trying multiple operating systems is. Just install a few browsers and try them out
If Firefox works for you, I'd recommend it. I could make a huge list of my subjective pros and cons, but who cares what I think?
The most important thing is that I'd recommend getting off Chrome, because Google is attempting to use their market position to make the internet worse for users. Try all the alternatives and see which one you like.
firefox is fine as browsers go. they've had some missteps recently with some unpopular decisions surrounding ads. brave has some controversies surrounding cryptocurrency and affiliate url links, as well as being chromium based. if those things bother you, and you are adverse to the ad issues, you could go with a fork of firefox, like librewolf.
I far prefer Firefox for basically every case. I honestly do a fair amount of surfing on a Raspberry Pi 4 and Chromium is unusable on it while Firefox is quite usable. And that makes me think Firefox is lighter-weight than Chromium.
I do a lot of web development and prefer Firefox over Chrome/Chromium for that purpose as well.
Brave is way too cryptocurrency-adjacent for me to be comfortable with.
I was already using Firefox well before the whole WEI thing with Chromium went down. But that made it clear Chromium isn't to be trusted.
All that said, Mozilla haa recently gotten in bed with advertising companies and talked about adding AI "features." I don't trust that Firefox will continue to be any better than Chrome.
I use Firefox for just about everything. More specifically, I use a couple privacy-oriented Firefox forks. I like Librewolf as my daily browser and Mullvad Browser as my "view-once" browser. On mobile I primarily use Mull.
Librewolf is great for me because it removes some of the Mozilla fluff that I don't use (Mozilla VPN, Pocket, etc). A lot of people would likely prefer using the arkenfox.js user configurator simply because it'll allow you to keep up to date with Firefox's native update installer.
Occasionally I'll use Brave on desktop- I find that a Chromium browser not using my strict uBlock Origin ruleset is generally more ideal for college and work-related use. Your mileage will vary considering your use case, but there's no shame in having multiple browsers that you use for different things.
That’s just some straight up bullshit. The only way Chrome is better for development is if you’re one of those assholes designing sites to only work in Chrome. If you’re designing to support open standards, Firefox is clearly superior in just about every way.
