[Blocking Requested - why for this release]: qawanted to retest. I believe this is fixed in the latest build.

Simply following STR doesn't repro the bug. This issue seems to be dependent on websites. Some websites will make the bug occur when going back to it. So far I've only found one website that reproduces this. STR: 0) Enable pinning the web in developer settings 1) On Browser go to imgur.com 2) On the same window go to mozilla.org 3) Hit the back arrow button, and wait until it finishes loading - Site icon is gone upon loading completes This issue is reproducible on latest Flame 2.5 and Aries.

Does this occur on 2.2?

2.2 doesn't have pin the web implemented.

Guillaume will have a look.

I did the STR many times and in different settings but I failed to reproduce the bug. I tried going back and forth from the websites in comment 2 a lot of times. I tried to clear the browsing cache, on both a Z3C and Flame with the latest builds. I got the icon every time. Can you verify if this happens in the latest build and if so, please provide a solid STR.

This issue is no longer occurring. The behavior has changed on imgur. When I did comment 2 testing the site icon will appear DURING loading, and will disappear AFTER loading finishes. Now it's doing the reverse that icon is empty during loading and will eventually appear after loading finishes.

I also cannot reproduce this issue with the latest build. Close this bug as WORKSFORME.
