In dolphin browser go to Menu>More>Setting (scroll down)>System settings (scroll down), then uncheck "Open pages in overview." You should be good to go then with the screen size.

 

Try the mobile version of Youtube m.youtube.com (do not use www.) Oh and to delete bookmarks you just have to go to your bookmarks screen and long press on a bookmark you want to delete.

 

is it worthy having the hd dolphin browser?

 

Go to the bookmarks page. Press the bookmark you wish to delete and hold. A pop up window will show up, scroll down to "Delete Bookmark" and press.

 

Dolphin browser HD is ok. It does lag a little on the Hero. I still use the stock browser more.

 

Yea I tried the dolphin HD, never used any other browser except stock.

It lags and loads pretty slow for me, not sure if all the other browsers are this way but it really isn't worth having over the stock browser IMO.

 

I just downloaded it yesterday so I don't have a lot of time with it yet, but my early thoughts on it mirror yours. I think slower page loads for me. Feels a little sluggish to respond at times. Also no unique feature I find as a "must have". I'll give it a little more time, but my guess is it's getting uninstalled soon.
