I installed ZASS update to 9.1.507.000 on April 8th. When I connected to internet with Firefox browser I had no problems other than Firefox stayed open even though I closed through File/exit. I would use task manager and just stop the Firefox process and then log onto Firefox to go back online. But today when I went onto internet, loading Yahoo.com (my home page) became very sluggish. I went to several websites becoming a peeved as to how long it took for them to load. Then when I tried to go to some my bookmarks, the listing within folders would not come up. You could see the outline of listing not content.
Then I went into ZASS and stopped Forcefield and now have no problems with bookmarks.
I remembered that I had once downloaded Forcefield program and had major problems with earlier verison of Firefox.
From this I think that Forcefield and Firefox don't like each other. Also I use Firefox as my default browser as I just don't normally use IE 8.
