Wich mobile devices do you use ?
I can try that browser. Just hope it's not as clumsy as Chrome or Firefox for Android.
EDIT: Unfortunately, it is. It won't let me sync my bookmarks from Google Chrome. Oh well, uninstalling.
Personnally, I have those ones : a Sony Xperia Z3 (smartphone) and a Sony Xperia Z4 Tablet (no need to explain ) and Firefox runs smoothly on those ones. Back from my old Nokia N900 the old Firefox was really usable too.
I have an LG G Stylo from Metro PCS. I'm currently using Boat Browser because it's the closest to a desktop browser I can get on my device. I've actually had a Linux virtual machine with the desktop version of Firefox on my Android phone at one time, but there were still way too many limitations with it. And it was impractical.
EDIT: Just realized there was an update for Boat Browser, but it's plagued with ads and performance issues. So I won't be updating anytime soon.
