I'm a fan of Cero-WRT: http://www.bufferbloat.net/projects/cerowrt Works well with Netgear routers (a couple of models) and my wireless links stay up for weeks on end.

I've been on the "Nightly" branch (8.0a1 at this writing) for the last couple of weeks (Win 7 Pro 64-bit). It's the only native 64-bit release, and crashes/hangs far less often than Firefox 4/5 ever did. I'm disappointed that Mozilla *still* won't publicly release native 64-bit binaries for Firefox, so I'll stay on the Nightly update path as long as I can. I only have 1/2 dozen add-ons, and they seem to be working fine.

I use Thunderbird to access my gmail account via IMAP. The best of both worlds!
