Downloading on FF mobile is veeeery hit or miss in lots of aspects, one of those things where I wonder if the devs ever use this thing.
I don't have problems with it, so they might not be able to reproduce it either...
Which is completely fair. It's not consistent for me either; most of the times the download just works, sometimes it doesn't, sometimes it does but takes a little while (specifically for larger downloads) except Firefox doesn't actually tell me it's in progress and cancels the download if I leave the app. It's all around very confusing.
Having issues with it as well. Mostly when downloading things that need me to be logged in somewhere
More or less the one functionality I have never seen even a whiff of an issue with. Click link, get asked for download, hit download, it downloads.
I've never seen any issue with it, at all.
