I use the Dolphin browser but on the standard browser you would need to go to the market and get the app called " Bookmark sort & backup"
Hope this helps,
whats the advantage of using the Dolphin browser compared to the standard browser? ive seen people talk about it but havent really seen anyone talk about advantages and so on.
tabbed browsing - you can clear cache upon exit - has a read later option kind of like a temp bookmark -
has a lot of little extras that make it a better interface - its free so try it for yourself
It also gives you the ability to sort by date or by title.
