And, Firefox again

Again, a doubt on FireFox,

I have a system with a few users. Just one (the new one) opens a Firefox without any word on it. I mean I see icons for preferences, extensions, etc, but nothing is written beside it. This is the same if, for instance, one clicks on preferences icon: no mentions to advanced, proxys or whatever.

The closest I found to this was this,

There it is suggested that possibly text is white on white background …I don’t think I understand what I should do to correct it nor what could have caused it.

I’ve already tried removing .mozilla but didn’t help.

Any idea?


Workaround: Deleted new user and Add new user again. Now Firefox works fine.

Don’t have a clue of what I did to cause the Firefox problem …
