I was trying to install the Noia eXtreme 2.0 theme using the theme installation
method on the Firefox themes page.  That page was taking a VERY long time to
load due to waiting for some images so I browsed another site in a new tab.

At some point, I did something (not sure what) that generated a segmentation
fault.  I was trying to track down another segmentation fault I encountered
previously SO I ran Firefox under gdb when this segmentation fault occured. 
Here is the backtrace:

Program received signal SIGSEGV, Segmentation fault.

[Robin Monks]

I'm moving to Theme/Extension Manager.  Does this still happen in 0.9.1?

Comment 2

[Tom Williams]

I haven't had any problems installing a variety of themes using Firefox 0.9.1 so
this bug report can be closed. :)

Peace...

This is a dupe of a recently fixed bug.
