After I don't know how long and found by accident:angry:
Could only fit about 8 tabs in FF before they went off the screen with that > pointing to the rest.
Why didn't someone tell me you can right click your tabs - properties and delete part of the name.
Instead of having a tab named "CCleaner Forums (Powered by Invision Power Board)" just have "Ccleaner".
Now I've got 18 tabs all in view.
You mean the bookmarks on the bookmark folder I assume (not the tabs). You can also reduce the font size and padding round the button to fit more on with a simple userchrome code. This is what I have in mine:
/* change bookmark toolbar font */#personal-bookmarks .toolbarbutton-text { font-size: 7pt !important; font-weight: !important;}/* change space around bookmark toolbar icons */#personal-bookmarks toolbarbutton { margin: 0px 1px 0px 1px !important; padding: 0px 1px 0px 1px !important;}/* decrease space between bookmark menu items *//* main menu - folders */menu.bookmark-item > .menu-iconic-left { margin-top: -1px !important; margin-bottom: 0px !important;}
