Downgrade Firefox Android to last known good version.

more options

I used to have a working version of Firefox in my Android tablet. Unfortunately I had "automatic update" feature enabled, and the existing Firefox was replaced with the "August 2020 update". This update basically removed all the features I liked and needed, and introduced new features I do not like or need. From my point of view, the current Firefox Android is totally useless.

Question: Is it possible to replace the current Firefox Android with the last known good version (that is, just about any version before the "August 2020 update")? If it is possible, could you tell me how to do it?
