This thread will probably get archived and locked, but I'll restart another one anyway. Firefox seems to be degenerating in terms of UX an stability, and especially if people are running custom OSs like lineage OS, it's unlikely that the latest android version will actually install at all. As a result, a lot of people are installing older versions of firefox, especially versions which allow access to "about:config" so firefox can be modified to be usable.

When googing for this, there are a lot of non-mozilla websites offering downloads, filled with God knows what malware added. It would be better if there was a permanent archive of all the previous versions, including the nightlys, so that people could at least access the older, working, versions from a trusted source. You might think this would be a bad security choice, but the current situation is worse.
