Unless they changed it, mobile Firefox is locked to a limited set of extensions unless you:
- Use Nightly.
- Create a Mozilla account.
- Log in to that account on the Add-Ons site and create an add-on collection with all the extensions you want to install.
- Set that collection as your source of add-ons in the Firefox settings.
You’re also unable to use about:config unless you’re using Nightly (or maybe Beta). So Nightly is really the only version worth using since it doesn’t have nearly as many artificial restrictions as the stable version does. This is also true to a lesser extent on desktop where you have to use Nightly to install unsigned extensions.
You also can’t open any offline HTML files for whatever reason and on devices with very little RAM (like 2GB) Firefox isn’t viable, but Chrome-based browsers work mostly fine. Firefox is still the best mobile browser though, mostly because it supports extensions at all.
The article you linked makes a big deal about literally nothing. We’ve known Chrome was going to drop MV2 for years. We also know Firefox won’t. There is nothing more they have to do or say about this situation. It doesn’t affect Firefox whatsoever.
“Suspiciously silent” is such a bullshit nothing accusation to make. It is so obviously trying to capitalize on how many users have been (justifiably) turning on Mozilla as of late.
