When I click on a link in Thunderbird to open in Firefox, I get the following error.

XML Parsing Error: undefined entity Location: chrome://browser/content/browser.xhtml Line Number 760, Column 13: 

           <toolbarbutton id="UITourTooltipClose" class="close-icon"
</pre>

I am unable to resolve the issue. Is there a fix for this error?

Thanks in advance.

This can be caused by a failed Firefox update that left you with a mixture of old and updated files in the Firefox program folder. This can happen in case security software was keeping a handle of some of the files in the Firefox program folder preventing Firefox from replacing all the files. You need to do a clean reinstall and remove the Firefox program folder to ensure that all files are replaced. You may have to disable security software temporarily in case the problem persists.

You can create a new profile as a quick test to see if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
