There is no "add tab or + tab" and no "list all tabs" button. I'm also missing the add-on bar that is supposed to be at the bottom. I'd love to try all the features but it's hard to do without these options.

The first day I downloaded Firefox 4, I had the "+" tab at the end of the tabs but after the first day, it disappeared so to open new tabs, I have to go to the Firefox tab on the left or use ctrl+t to open new tabs.

The "list all tabs" button appears sporadically and today is completely unavailable.

The add-on bar has never been available.

The "feedback" button appeared the first day or so then disappeared, never to appear again!

Create a new profile exclusively for the Firefox 4 version and create a desktop shortcut with -P "profile" appended to the target to launch that profile.
