Firefox, mostly because I use mobile browsers so infrequently that the choice makes almost no difference to me (So I use what I use on desktop). Having μBlock Origin is nice too. There are a few things that annoy me about it, like not remembering which sites I set to view in Desktop mode, but overall it works fine for what I need.
I was using NoScript with Firefox mobile and it recently started breaking websites for me. Many wouldn't load at all until I went in and started disabling NoScript for the domain. It got to be such a hassle that I uninstalled it completely. If you have a configuration guide for it, I would be interested.
Also of note, I never changed any of the default settings. It just started breaking websites one day. Took me a few days to realize what the culprit was.
I'm using Firefox Beta, it's always my default with Ublock Origin. I used to have Firefox Nightly for the pull down to refresh option but it was buggy when scrolling up.
I also tried Vivaldi and Samsung Browser with bottom tab bar, I feel way more productive there, wish firefox had this option too.
I also use Firefox but it became really.. Weird lately? For example, when I click on a link in another app, which opens Firefox; the app just freezes? I can't give any input to the website but I can still switch tabs. It's super weird...
Unblock Origin in the browser is a godsend and I can't imagine going back. It even makes YouTube usable again, if you can live without the native app feel. I mean, I could pay for YouTube premium but then again! It is mostly waste of time anyway :)
I only use Chrome when Firefox has trouble rendering some page.
I use Samsung Internet Browser. I like being able to have my tab bar, and address bar at the bottom of the screen. It has dark mode for all web pages, it also gives me the option to use my system font for the web pages. Has ad blockers that you can install, so I never see any ads.
Three browsers. Compartmentalization. Mull, Fennec, Mulch. First for everyday browsing, second for government, spyware services, third if second is too restrictive for some sites with blocking trackers.
Until a year ago, I was using Firefox. I made the switch to Brave, because I wanted the Chromium functionality ( I still think Chromium is designed perfectly to use on mobile. ) but I didn't want any ads ruining it.
But, that might change, I heard about Kiwi here, I'll definitely take a look, extension support with Chromium functionality, that sounds too good to be true. Definitely will try.
Edit: Definitely try it, you will love it. It's not just Chrome with extensions. It also has some features you are missing on mobile, like DevTools. It has Chrome's own 'ad blocker', may not be effective but I downloaded Ublock, which gets the job done. Super, super cool.
I was using Samsung Internet but stopped because it simply does not work with Bitwarden's auto fill. Moved to Firefox but it is comically slow, takes at least 10 seconds to load any page. I'm now trying Vivaldi and so far I have no immediate complaints.
Firefox and Vivaldi. Both have ad blockers and bottom address bar. With Firefox I use some additional add-ons, like Consent-o-Matic, but the Vivaldi interface is nicer and very customizable. I also use the DDG browser for occasional searches.
The regular Opera browser also has that feature. My Flow can also be linked between Opera and Opera GX. Sadly, I don't see a similar feature in other browsers.
Ecosia for me. I keep important internet usage off of my phone and I am by no means power user, so "functional", "unobtrusive", and "does a small good thing" was basically everything I could ask for
Firefox for general browsing. Firefox Focus when I want privacy (it can help get around some paywalled news sources.) If I need to use a Chrome based browser, I use Samsung with an ad block.
Up until two years ago, my go to browser was Iceraven & sometimes Firefox. But then I came across Kiwi (chromium browser with extension support).
For me Kiwi gives the best page loading speeds, compared to Firefox & iceraven & the difference is very much noticeable. I've turned off all the default data collection in kiwi if that matters.
