Mozilla Firefox debug and answer, ASSERT: *** Search: _installLocation: engine has no file!

[ismail AKBIYIK]

#### PROBLEM
After doing an update in Fedora 9 to Firefox I now get the error
message below when it starts. I also cannot enter anything in the
address bar or open the addons dialogue or organize bookmarks. I tried
uninstalling and reinstalling firefox, renaming the .mozilla folder
and so far no luck. I'd like to uninstall addons one by one by
deleting the files associated but I'm not sure how to do that. If
anyone has any suggestions I'd appreciate it.

ASSERT: *** Search: _installLocation: engine has no file!

#### ANSWER

You must install --> xulrunner-1.9
Description about xulrunner:
XUL + XPCOM application runner
XULRunner is a single "gecko runtime" that can be used to bootstrap
multiple XUL + XPCOM applications that are as rich as Firefox and
Thunderbird.

XUL is Mozilla's XML based User Interface language that lets you build
feature-rich cross platform applications. These applications are
easily
customized with alternative text, graphics and layout so that they can
be
readily branded or localized for various markets. Web developers
already
familiar with Dynamic HTML (DHTML) will learn XUL quickly and can
start
building applications right away.
