I have tried this add on/extension and starts out fine but then it will not work and you will loose your bookmarks that you save.
I even have backed up but it will not load them back up all I get is .... " Sorry the add on is not working and then you have to delete it and reinstall but why go through all of the hassle in the first place?
I tried it 2 times and after a couple of times it will still do the same thing .... Not going to install anymore....
