I have been using this extension for a long time. On mobile fennec and in desktop firefox, and more recently also in chrome and edge! (I put it from the "developer mode") This is generally the best extension in the world! Now, after it became available, I put it on the official firefox 120.1.1 on android. Everything is just as great, but until the settings > translations >automatic transfer link leading to the same domain is selected. "Yes" is not available. I think this is because you need a special permission to read the visited domains.
