Going to Firefox 1.5

Are there any problems going from 1.0.7 to 1.5? Like plugins/extensions not working?

The 4chan extension is incompatible, is really the only major problem I've encountered. You can force compatibility, but it's actually broken (surprise surprise)

Some extenions like Adblock, Gmail Notifier, Web-Dev Extensions breaks in 1.0.7, but they're solved by...

Adblock, Replaced by Adblock Plus for 1.5
Gmail Notifier, updating it to the latest version fixes it.
Web-Dev Ext, same as gmail notifier.

my 0.02
