I am a long-time user of Firefox, and generally think it to be a good browser. I’ve toyed with Google Chrome, but generally find myself coming back to Firefox.
As such, I recently updated my version of Firefox to 3.6. Having successfully upgraded, I am taken to this page:

How pretty! It proudly tells me:
Thanks for supporting Mozilla’s mission of encouraging openness, innovation and opportunity on the Web!
It’s here that I start to have issues (other than the ones you are abundantly aware of).
Issue 1:
How exactly have I “supported Mozilla’s mission of encouraging openness, innovation and opportunity on the Web!”? Because I’ve updated my browser? Feels like Mozilla are disappearing up their own sockets.
Issue 1a:
In addition to the above, if you click the link for ‘Mozilla’s mission’, you’re taken to a page that explains who they are and what they do. Point #2 on that page says:
We’re a public benefit organization
dedicated not to making money but to improving the way people everywhere experience the Internet.
Um: so what about all that kick-back revenue Mozilla get from Google by having them as the default search engine for Firefox?
Issue 3:
From a web usability angle, this is the bigger one. On this ‘update’ page, the user is informed they can choose from over 35,000 themes for Firefox. At first, you think “That’s awesome!”
And then you mouseover some of these themes to try them out – only to realise that, for anyone other than a basic user with no bookmarks on their toolbar, or any toolbar extensions – the majority are unusable. Check out the screenshot below of how one of these themes looks on my version of Firefox with various extensions:

How is that any use to anyone?!
Rant over.
