What exactly is XUL.mfl?

It seems such a large file in relation to the rest of the app.

Thanks,
Adam.

XUL cache

The entire FF interface is written in XUL. That file is the cache of said interface elements. It was always disabled in previous instance of Portable FF )to save space) but was enabled for 1.5 as it caused odd display issues.

Sometimes, the impossible can become possible, if you're awesome!

No problem!

I've disabled the Xul cache on FF 1.5 and really I don't have any problem!

@Spiceskull: you can find more info about Xul cache here.

I've experienced them

firsthand with FF 1.5 and some extensions. Turning XUL cache back on made the issue go away. Turning it back off caused the issue to reappear. It mainly occured with 1.0 profiles that were upgraded and was a partial cause of the large extra space at the bottom of the screen above the status bar issue.

XUL.mfl

Well,

It seems like it is an important component, but I will have a look at the dev tips link - thanks.

Adam.
