Hi !
Let me introduce my last extension for Maxthon browser.
It's a shortcut for yours favorites online ...
so (unfortunately for someone of you) this extension is only for users signed to Maxthon Passport.
It's just a workaround at the moment - let's hope we'll get a true fav's on the sidebar someday ...
To manage your fav's (add/ remove/ rename) you still need a Infobox !
OR
Just use another version of this extension ( named favs2) from my attachment...
So this time it uses fav's from Infobox.
favs.mxaddon
favs2.mxaddon
