After upgrading to Mozilla 1.7.2 and Firefox 0.9.2 I found I couldn't use these sites any more: http://www.geocities.com/ogidnic/oforums/std.html http://home.iprimus.com.au/cognidi/forums/stsd.html I found from the Mozilla release "known issues" that I could change the Mozilla/Firefox configuration to allow me to use the multiforum sites by making a small change to the configuration settings. To work correctly, this site format needs to be able to load links from frames into frames from other sites and permit form submission. I am aware of the reasoning behind preventing this action and don't dispute its security value. But being able to use this site is important for me. The forums - there are several with thousands of regulars - have a unique design on their site of origin (http://www2b.abc.net.au/science/k2/stn/ which I don't use because of the newsticker which upsets some other software I use). Most of the regulars use one of the multiforum sites but most of them also use internet explorer. I upgraded Spywareblaster to version 3.2 today and now can't use the multiforum sites again. It would appear Spywareblaster has prevented "one site targeting links and form submissions into a frameset created by another site" as well and there doesn't seem to any option I can change that would permit me to use those sites the way they are designed to operate. Disabling all protection does not restore this function in Mozilla. I would prefer to be able to keep using both Mozilla and Spywareblaster. But I won't be able to keep Spywareblaster if I can't solve this problem. Internet Explorer is not affected and still allows the sites to work properly ? Surely a bigger problem in Internet Explorer than Mozilla. Windows XP SP1 fully patched.
