5 stars: Great browser, designed from the ground up to not be creepy. Haven't found a page that doesn't load properly. It's lightweight and fast enough. I like that when you end each session it closes everything; no open tabs sitting for weeks. This is Mozilla keeping up its solid commitment to a better internet.
3 stars: Secure to the point of unusable. Had it on my work profile but you can only use it for basic web browsing. No login or SSO even with the tracking protection disabled. If you have both Firefox and FF Focus installed links won't offer you the 2 as options. Focus has to be uninstalled for regular Firefox to show up as an option.
3 stars: This browser doesnt have tabs, and it's not clear from the description. It's strange that you can still long-click links to open in a new tab, but it actually opens in the same tab. Otherwise the browser seems nice to use and convenient for privacy. I really need tabs, though.
3 stars: I would say this is the best mobile browser for phone usage where you want to easily de-gunk things often and want to maintain some privacy, but it isn't, yet. Firefox has several accessibility features like the ability to zoom any page or the ability to prefer dark themes even when you have other privacy controls turned on, but you can't do it here. Maybe it'll happen, but seems not to be a priority.
3 stars: Great default browser for quick searches. You don't have to remember to clean out your history and there are a few feature...
