Firefox 4 has a new tab button (marked as a +) just like the Firefox 3 versions. In Firefox 4 that button is on the tab bar and can be dragged to a different position on the tab bar (e.g. at the left end) or on another toolbar.

That's not really what I'm looking for. What I'm asking is there anyway to do what I highlighted in the picture below so New Tab is above Reload Tab?

Not that I know of. You can use File > New Tab or Firefox > Tab in addition to what I posted above.

Maybe an extension like Tab Mix Plus can add that feature to the Tab bar context menu.

Thanks! The Tab Mix Plus did exactly what I needed.

You're welcome

It is possible to customize the right click menu download an addon called "menu editor"................

I've wanted to restore the right click over an existing tab to get the "New Tab" option also, finally took the time to search until I found this thread. I'll try the add-on mentioned here but wanted to toss this out as well: a lot of customization was done using about:config in FF3. You can still get into the config in FF4 and I'd rather make changes there than loading up a new extension each time I want to make a change. From experience, the more add-ons/extensions I have, the better the chance FF will behave oddly, and when that happens figuring out which extension/combo of extensions cause the problem is a wear out. I used an old config modification to bring back the [x] to close the open tab on the far right side of the browser's window shortly after installing FF4. There were two changes to make in FF3, one of the two config options no longer exists in FF4, but the other does and it works. I'd love to know what happened to making changes via config instead of extension....
