[Regression range]:
- The issue is NOT reproducible on 56.0.2. I will get back with the regression range as soon as possible.
Not sure how rich icon collection would affect the search box.

mak do you have any idea on this? Is it similar to bug 1403504?

I think it's because of this:

Basically the code assumes by the time we handle a "Link:AddSearch" message, mIconURL has been populated, but that's no more the case since we delayed icon handling.
I'm still not sure how to fix this, we could delay "Link:AddSearch" to after icons have been analyzed and mIconURL has been set, or make _rebuildAddEngineList async... Maybe worth asking Florian what he thinks.

So I can reproduce this issue on today's nightly.

Looks like Firefox successfully collected the icon and persisted it in favions.sqlite, but the search box didn't show it due to the delay that mak described above.

Last time we had a search icon issue with, it was because they use an SVG icon (see bug 1240729), is there any chance this could be the problem again?

I don't think so. In my case, it's just a regular ico file in the favicons.sqlite.
no, this is due to our changes, we delayed setting mIconURL but AddSearch expects it to be set already.
We looked at the problem on IRC, and Florian pointed out Bug 361923.
There are 2 bugs, but only one is likely affecting most users.

1. if the user should open the panel really quickly after a page load, due to the delay we added in bug 1352459 on <link> handling, mIconURL may not be set, and we could end up without an icon (comment 3). This is unlikely to hit users though.

2. If the openSearch xml file doesn't specify an icon, we use the page favicon. In this case the page has 2 favicons, and looks like now we pick the ico file, that is larger than 10KB (16KB indeed). Bug 361923 says we just discard icons larger than 10KB.

Based on the fact users of baidu are likely to have it as one of the default engines (and that has no problem), and in the past we shipped multiple versions with a similar bug and was not considered critical, we are prone to consider this a wontfix for 57.

I'll verify that Bug 361923 is indeed our problem here, end eventually we can bump the limit a little bit here, or try to resample the icon.
This will be fixed by bug 361923.
I don't think it's worth to keep a bug open for the timing bug; while valid in theory, it seems unlikely to happen in practice.
Thus, I will mark this as fixed once the other bug is.
