For starters let me say this is not something new to the recent NIS update. This occurred prior to the update, too.
NIS 12 on Win XP, with Firefox 9.0.1. When I do a search using the Toolbar search box for Norton Safe Search (ask.com), I don't seem to have a problem in Firefox unless I use Firefox's backup arrow to go back to a previous page. Several times it has crashed when using that backup arrow. It may be a Firefox problem, but it's only happening when backing through search results. It's not terribly problematic, because I know to avoid doing that. I was just curious if anyone else has been seeing that.
I realize there is a new Firefox version 10 out, and I plan to do that soon, too.
Thanks.
