That does not tell me why they are in each of my profiles or how they
are used.

They are Mozilla FastLoad files, they store temporary compilations of UI 
files so we can load them faster than if we  need to parse the original 
UI definitions again. You can do nothing but leave them as they are, but 
you can safely exclude them from backups, as they are automatically 
regenerated when they are missing.

Unfortunately only the cached version is working and I haven't the time
to look for other sources:

 XPC.mflA cache file for components (XPC)
 xul.mfasl (Linux) See XUL.mfl file
 XUL.mfl (Windows) Cached user interface data. Can be deleted to resolve 
 various issues.
 File location changed in Thunderbird 1.5. [3]
 XUL FastLoad File (Mac OS X)  See XUL.mfl

Hm, sometimes the XUL.mfl becomes corrupt and must be removed manually.
Therefore i have set

- user.js -
// XUL-Caching und XUL.mfl abschalten
user_pref(nglayout.debug.disable_xul_cache, true);
user_pref(nglayout.debug.disable_xul_fastload,  true);
---

No XUL.mfl in my profile anymore and i haven't noticed a noticeable
delay at startup. :)

You must have a very very fast machine then, as even I with a dual-core 
machine notice my builds being slower in startup and more sluggish in 
usage when I set those options.

Me neither. But i couldn't because if have no XUL.mfl since years. *g*

Just tested. After a reboot the first start of SM2.1 lasts 9 seconds
without XUL.mfasl and 7 seconds with XUL.mfasl. After quitting the next
starts lasts about 2 seconds regardless of XUL.mfasl.

My machine is a Core 2 Duo E6750 with 4GB RAM. I am on Linux, therefore
the filename is XUL.mfasl and not XUL.mfl, but that shouldn't matter.
What could matter is, that i am using only a few extensions.
