For me it's the ability to install extensions. I can't browser without the dark reader extension. If I look at bright screens for long time, I get a headache and won't get sleep

Cookie banner reduction already exists usint uBlock. You just need to enable some additional lists

That's the reason why I might start to use FF again (tbh at this point I don't see why to use anything else).

I use Firefox on Android and it's great. Ad blocking is the big one but it's just a good browser. I deleted the Twitter and Reddit apps recently and Firefox lets me bookmark the sites on the launcher so it's like a separate "app" but not taking up 100s MB of space and I can block ads on these sites. I'm hoping that I'll be to use the Twitter desktop extension that prunes even more junk out of the experience - recommendations, what's trending and other clickbait garbage

Are you a developer? If not then the only thing you need to know is that Mozilla is essentially announcing enabling desktop extensions to be able to work on mobile

Firefox Mobile supported add-ons for many years, but due to having to change some things under the hood a few years ago, add-ons got restricted a bit (though you could still use them).

They're basically announcing they finally fixed the issue and they're coming back.

Firefox for Android previously only supported a limited number of select extensions. They're finally opening it up so you can use any extension.

They don't spell this out, but my interpretation is that extension devs will be able to publish extensions for use on Android, without Mozilla explicitly approving each one of them.

Many desktop extensions work as-is on Android, so when this goes live, we'll likely see dozens, if not hundreds, of extensions becoming available in the following weeks.

Finally. You've been able to use desktop addons this whole time, but you have to do a whole runaround:

• Create Firefox account
• Sign in on desktop
• Install the add-ons you want
• Create an app collection and publish it
• Sign in on mobile
• Enable developer mode
• Download your custom app collection
• (Optional: sign out on both devices)

uBlock on Firefox mobile has been out for a while now

you can use ublock origin on android firefox right now.. been using it for years.

I use it since maybe a year now on Android and it's amazing. The toggeling of the overlay and weird zap objects/overlays function takes some getting used too but otherwise its just like on the Desktop.
