If you have Ublock Origin installed, you can add the bypass paywalls clean filterlist and it will work. That is what i did.

Firefox nightly is a pain, you can make a collection on desktop, and add that collection to the app. It's trial and error which extensions work.

The easiest way is to add "https://12ft.io/" before the article's URL and it will bypass the paywall

I've tried and tried to install the bypass paywall xpi in Firefox nightly on android and I just can't get it to install. It seems like FF has no clue what to do with xpi files anymore.

I tried the install.html trick I found on stack overflow but FF keeps downloading the xpi and won't install it. The GitHub extension installer no longer exists. Root explorer and other file managers dont work.

Good luck! I'll be checking back to see if anyone gets it figured out.

Kiwi browser with bypass paywall clean extension

Ublock Origin should give you a lot of mileage. However, consider using Fennec F-Droid because it allows other extensions like Tampermonkey, which you can use to install userscripts.

I found one solution. At least it works for WSJ. Firefox has a "reading mode" button next to the url. That seems to bypass the paywall

In my experience, 12ft fails to work many times and does not support a wide range of sites. The best way to bypass news paywalls is to use Bypass Paywalls Chrome Clean extension, which is available both for Chrome and for Firefox. It supports many sites, and has recent updates. Browser extensions on Android are much limited, but the best Android browser I found to support extensions is Kiwi browser. Another browser I heard that has supports extensions is Orion browser, though I have not tried it.

Could try searching the url on archive.is or one of its mirrors.

This is what you gotta do yo. Go to the gitlab repo of bypass paywall clean, there the Dev says to install an old version of FF that can install add-on from file then update. link here
