Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[arni2033]

Attachment: screenshot 1 - (A), (B), (C). Openning sidebars can deform user interface (UI) and prevent user from resizing the window.png

STR:   (Win7_64, Nightly 45, 32bit, ID 20151102030241, new profile)
(A)
1. Close bookmarks/history sidebar
2. Open devtools on this page, dock it to the right side of screen, resize it to make devtools sidebar as wide as possible
3. Open new tab
4. Open bookmarks/history sidebar
(B)
1. Maximize window, close bookmarks/history sidebar
2. Open devtools on this page, dock it to the right side of screen, resize it to make devtools sidebar as wide as possible
3. Switch window to normal mode, resize it so that the window's width was ~50% of the screen width
(C)
1. Maximize window, close bookmarks/history sidebar
2. Open the following attachment from bug 1208489 which is trying to open a popup window
> url https://bug1208489.bmoattachments.org/attachment.cgi?id=8666006
3. Make sure you see notification about blocked popup window at the top of the page
4. Switch window to normal mode, open bookmarks sidebar
5. Resize the window so that notification's close button was not visible

Result:       [see screenshot] Browser UI is deformed; Can't click menu button (≡)
Expectations: Browser UI should not deform.

Note: I do not do (A), (B) and (C) on purpose. It's just happens by itself due to window sizing. I have to look through tabs (70+) to determine which tab is causing it.

Can't reproduce, so going to close this out.
