1224552 - Awesome bar with search suggestions enabled flickers with some search engines

Status: RESOLVED WORKSFORME

(Firefox :: Search, defect, P4)

Description

[Petruta Horea [:phorea]]

Attachment: flickers.gif

Reproduced with Firefox 43 beta 3, latest Aurora 44.0a2 and latest Nightly 45.0a1 2015-11-12 under Win 7 64-bit, Ubuntu 14.04 x32 and Mac OS X 10.9.5.

Steps to reproduce:
1. Start typing in the url bar and respond Yes at Search Suggestions opt-in prompt
2. Type 2-3 search terms with different pre-installed search engines: Yahoo, Bing, eBay, Amazon, Wikipedia, DuckDuckGo
3. Notice the awesome bar pane while typing

Actual results: The awesome bar flickers while retrieving suggestions.
This seems to happen when network responses pass 300ms, but this value is also reached for search bar panel searches , and here there are no flickers.

Expected results: No flicker. Google search engine set as default doesn't seem to have this issue

Notes: - May be related to bug 740043, but setting browser.urlbar.delay from '50' to '0' doesn't have any effect.
- Reproduces with Nightly 42.0a1 20150723030207, so it's not a regression

yes, the flickering code can't work properly if the network delay is too high, the risk of showing the user wrong results then would be too high.
I don't think we can do much, it's an intrinsic limit of the way we use to avoid flickering in the most common cases.

I think this is currently WFM.
