I was just in a newsgroup with Thunderbird, when an Alert box appeared. No text appeared in the alert box, so at first, I did not know what the alert was.
I then went into SeaMonkey into the same newsgroup and an Alert box appeared with text, indicating what the problem was.
Is the lack of a font in the Thunderbird Alert box (attached), a TDE setting perhaps?
White font on white background?
You can probably swipe/select the popup's content to see a change in colors that will allow it to be read.
I changed the window (theme?) back to the default Plastik, with the same result (attached). So it doesn't appear to be theme-related.
It's not likely about any TDE theme per se, but a styling conflict related to GTK theme. I use other Mozilla products, but not TB. Based upon the others' behavior, it may be possible to inspect the contents of the window with Ctrl-Shift-I to find out what CSS rule causes it, then create a CSS rule userChrome.css in the chrome directory of your TB profile (which probably does not exist, as it's optional - you'd need to create if not). Selecting/installing some other GTK theme would probably be much easier. Both TB and SM (and FF) normally are similarly affected by whatever your GTK theme is.
