Thanks .

Of course the "browser-only theme change" approach from Issue #2 would sort of fix my problem, too, since if the browser used one of the Maemo GTK+ themes with a white input field background, the black-on-black thing goes away. This would also still be more elegant than the user CSS workaround which conflicts with site stylesheets that do apply their own formatting to a degree that causes the GTK+ widget not to be used (e.g. if I force text color for <input> to white via user CSS and then a site comes along that gives their input fields a pink border and a mostly white background image with pink polka dots ).

That said, loading up another theme to use in the browser is probably more resource-intensive than changing the behavior as suggested above ... MicroB only get this for "free" because it uses/activates Gecko's old pre-GTK-integration codepath where Gecko gets to draw its very own simple Windows 95-like input field widgets, I guess. The other downside of using a different theme is losing the extra integration provided by using system widgets when possible in the first place, but then the LCARS widgets don't really fit into most websites visually. As in, they're not very neutral-looking.
