Hello, I've recently decided I want to delete a lot of my bookmarks. I probably have about 10.000+ of them and most are not needed at all (they come from StumbleUpon likes). However, I cannot delete folders of bookmarks or higher numbers of selected bookmarks. Everytime I try to do that, my Firefox becomes unresponsive and my CPU usage goes to the maximum. It doesn't delete them like this either. Numerous times I've terminated the unresponsive Firefox process and after restarting, all of the bookmarks were in place. I can only delete smaller numbers of bookmarks (like 20-30 at a time), but considering the huge number of bookmarks I have, that would take a lot of time. All of my StumbleUpon bookmarks are sorted in only about 10 folders or so, so I would only need to select one and delete it, if that worked. Is there a workaround for this? Or some alternate way of deleting bookmarks, without the Bookmark Manager? Thanks!
