Fixed
- With Zen's see-through pages on (
browser.tabs.allow_transparent_browser), the
toolbar didn't take a website's colour (#542): it came out black, or the colour
of the space behind the page, since 2.100.5. Websites are read from their own
picture again; Settings, the other about: pages and the empty tab still take what
shows through them. Thanks SoaringGecko.
