I would love to go back to Firefox as my full-time browser, but I have handful of showstoppers that I haven't found a good way around:

- Inability to run a private browsing window at the same time as my regular browsing. - No desktop notifications. (There appears to be an outdated and/or unmaintained add-on for this?) - No working equivalent of a few app-specific extensions (Google Voice button, Google+ +1 button, Google Reader inline previews)
