huh?

I want to change from tab to tab like when you pass the pages of a book. I had that to many years ago, but I forgot how to find it. Please if any can help, thanks a lot.... Blesses...

You can use "Ctrl+Page Up" and "Ctrl+Page Down" or (Shift+)Ctrl+Tab to go to the Previous or Next tab. See Keyboard shortcuts - Perform common Firefox tasks quickly

Are you talking about the Tabs being on the left side of the browser windows, instead of being on the top?

First, thanks to the people that take time to help, The Edmeister and Cor-el specialy. Ok, firefox have an add on, a feature to go from one tab to the other, and so. But is not clicking and see them one and other, its change like when you pass pages on a book, see??? If have more question, or Im not so clear, please ask me, and if that feature doesnt exist no more, sorry... Thanks and Blesses.... Edgar:.

I think that you mean rotating tabs automatically without pressing a key. Tab Mix Plus can do that if yo press the F8 key.
