Check iceweasel search engines update settings and behaviour

Downloading icons?

I suspect that’s right.

browser.chrome.site_icons is already set to false anyway, as it should be.

Still happening in 0.16 and the 0.17 pre-release.

Setting browser.chrome.site_icons, browser.chrome.favicons and browser.chrome.image_icons.max_size in user.js instead of the site-wide iceweasel.js does not solve the problem.

It seems Iceweasel only connects to www.google.com and en.wikipedia.org, that are (coincidence?) the only two engines without an icon in the search bar at startup time. A few seconds later, they get their icon, presumably downloaded from the Internet.

Next thing to do: test if TBB has the same issue.

See Iceweasel contacts all search providers on startup.
