When I switch from one network to the other, I have to close Firefox and restart, - otherwise I get "page not found". This is a minor inconvenience, but it works fine. My LAN setting is as follows: Automatic proxy configuration URL is http://proxy:8083/ However, each time I do this, Firefox adds a fresh tab and uses its own default home page - the one you get when you upgrade from one version to the next. I have SessionSaver loaded as extension. This is irritating, because now I have to also close down this new tab it adds in, every time I restart Firefox when moving from one network to the other. I believe this is a bug, and I found noone else to have logged it.

This is probably rather a core than a Firefox issue. See also previous similar reports for Camino bug 167900 and bug 327599.
After Bug 327599 was fixed, do you still experiencing this problem?
This is not reproducible for me with the latest Nightly. Please reopen if you can reproduce.
