i checked the FTP server and sure enough there is a build #2 listed ftp://ftp.mozilla.org/pub/firefox/nightly/11.0-candidates/build2/win32/en-US/Firefox Setup 11.0.exe i downloaded that and installed it after uninstalling the build # 1 version
I hadn't figured out the pattern, some sites just wouldn't display correctly, submit boxes wouldn't work, other anomalies. Upgrading to 12 Beta didn't do anything. I ended up uninstalling everything, at the same time deleting all traces in the registry. I imagine, some bizzare extension could have caused all of that havoc [I had plenty]. Interestingly, the issue kicked in straight after updating to 10.0.3. I had expected anything but trouble, lol.haven't noticed any yet.. which site is that?
