When I am looking for something on the web, I often open a second browser window to view things in. If I then continue browsing in both the original window and the new window, the browser regularly crashes. I expect this is a threading issue somewhere. The build is 2000041805, the standard M15 build for Windoze NT.

Bug 928 deals with the same issue but was for the old codebase. At the moment, bug 21507 is the oldest one I can find dealing with this issue. Reopen that one after confirming that this still exists on a newer build (yours is from 4/18, pretty old). *** This bug has been marked as a duplicate of 21507 ***
