When you pan around in pages like about:firefox and you have one of the sidebars open (for example the tab sidebar), the sidebar and url bar suddenly disappear after you've panned after a certain threshold. I see this happening on Android and Maemo. I see this only happening on about: pages. On regular pages, this works as expected. Maybe this is related to bug 597081?
Also happens when reloading the about:* page.
Steps to reproduce: - Go to about:firefox - Pan to the right to open the left sidebar - Pan upwards to scroll down Expected result: - The left sidebar should stay open Actual result: - The left sidebar is suddenly closed, after scrolling down for a while.
I know what you mean because I've seen this bug a few times, but for some reason I can't reproduce it today.
I can still see it happening on 2011-01-03 builds on Android and Maemo.
Created attachment 511771 [details] [diff] [review] Patch This is a regression from bug 598391. With this patch the testcase still works for me and I don't the wrong sidebars/urlbar behavior you were referring to.
