hi Bugsy21, you're right that advanced bookmark organisation isn't yet possible on firefox for android at the moment. the only workaround at the moment is to sync your tablet to a desktop device - then your bookmarks will show up on the desktop in a special "mobile bookmarks" folder, which content you can rearrange or put into sub-folders and synchronize those changes back to your mobile device.

Thanks for the solution. I know its possible in other browsers, so I assume it will be coming in the future. Generally I prefer Firefox on PCs, but I'm going to have to remove it from my tablet, not just for that reason, but also it keeps crashing.
