Sadie’s on Firefox? She strikes me as more a Palemoon kinda person...
I think she probably is, but afik she hasn't tried it yet (although the System Administrator has informed her of its presence..)
The System Administrator is running Palemoon of one of his laptops. For most intents and purposes he sees no glaring differences between it and Firefox. Mostly because there aren't that many... but it doesn't require an addon to get the addon bar.. ;-)
