1. Firefox Integration problems
Someone should file all the issues here which aren't filed into bugzilla.mozilla.org, and make sure that all of these block the meta GNOME integration bug.
1.1. User Interface
- uses its own notification popup for downloads instead of standard gnome notification.
1.1.1. HIG issues
- Has difficult Yes/No dialogs instead of explicit Do This/Do That dialogs.
- Preferences Dialog is not HIG-y.
1.2. GNOME library/settings integration issues
- doesn't use freedesktop spec to know how to open given file extensions. (Many distros appear to have a patch for this?)
doesn't share cookies/authentication information with gnome-keyring.
