Oh ! Finally this great feature has ressurected Noté 5 sur 5 étoiles

Thank you So much !
How I missed this essential feature .
I cannot understand why it is not built in FF - its basically getting toolbar buttons for "Show all Bookmarks" ,"Show all History" and many more , and opens them is a new tab instead of that useless window

THIS IS A PERFECT ADD ON FOR FULL SCREEN VIEW .

There used to be "Places in Tab" add-on ("Organize Bookmarks" button ) but has long died since FF 3.6 .
I cannot Thank You enough for not only reviving this essential feature , but making it much much better :
More buttons and the Genius "Tools" display feature in the tab itself .
And now that "History Submenus" is not working too since FF 5.0 Your add-on is the only way to access History tree in a fast way .

Two small tweaks would be nice :
1. option for it to open in current tab, not only in new tab.
2. shorter name for icons - when placed in bookmarks toolbar it takes unnecessary too much space ...and maybe write them in English too ;^)
