and simply create a new user agent -- I called mine "Firefox 8.0" -- and edit out the "Ubuntu; " (notice that the space after the semicolon is removed), that this temporarily fixes the "vnd.wap.xhtml+xml" problem, at least for the 4-5 sites I checked.
Note that the User Agent Switcher, when you create a new entry, prompts you with the default user agent string of your version of Firefox. Thus, this is really easy to do -- you do not have to create an entirely new user agent string, simply edit the default as I described.
Just for clarity, you (obviously) must switch your user agent to your new agent using Tools -> Default User Agent. Once you change it, the menu also changes (which I think is confusing at first), so in my case the Tools menu changes to Tools -> Firefox 8.0.
This did not fix the problem I'm having with one website rendering raw HTML -- the web interface for a D-Link DGS-1210-24 managed switch -- and I have tried using several other user agent strings (i.e., IE6, IE7, etc.) to no avail. So, I suspect this particular problem of mine is related to other changes within FF8 not having to do with the user agent string.
I have attached a screenshot of the relevant settings in my User Agent Switcher.
I can confirm that, as a workaround, if you install the User Agent Switcher:
