saves weaker machines Rated 5 out of 5 stars
I've found very difficult to handle multiple YTb tabs opened on my netbook without intolerable lagging. This add-on is a really simple solution.
And there is also no more the problem with automatically started videos on any site or with huge and wasteful flash ads.
Thank you, just keep going.
Very useful on weaker machines Rated 4 out of 5 stars
I found this add-on very long time ago, because I wanted something to restrict flash from slowing my netbook. Working very well...
But I see one shortage - for me (FF8, Windows XP & W764bit) is not working the synchronization feature. Even on the Sync server allocation is saved nothing by Flashblock. So one star down, but still great add-on.
