Diễn đàn hỗ trợ Firefox

additionally, i cannot use my mouse anymore to speed up scrolling through my favorites. also, i deleted a folder from my favorites, but that folder still shows up in my favorites.

On Windows I have my bookmarks arranged in folders. On Android each folder appears multiple times, with different numbers of bookmarks. I have re-installed Firefox on my phone. I had trouble syncing so I have exported from my PC as an HTML file, copied that to my phone and imported into Firefox. At the end, when I display bookmarks it's the same as before: see attached picture.

I've used extensions etc. to change this but nothing works. It's not even defaulting to the last folder saved in. Instead it stubbornly keeps using an odd folder I never selected for this purpose.
