Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[Richard Hince]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 GTB6 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 GTB6 (.NET CLR 3.5.30729)

Since install of 3.6.3 - When Firefox is near full screen (not maximised) and horizontal resize is attempted, either intentionally or by accident, the resize cursor does not always return to a normal mouse cursor and Firefox is temporarily hung. Hang can only be terminated by ctrl-alt-delete sequence - Firefox returns to normal immediately.

Related to this release, pop up windows crash or freeze.

Similar behaviour observed on all three of my commonly used computers which have differing displays / graphics devices / drivers.

Reproducible: Always

Steps to Reproduce:
1. Expand firefox to near full screen
2. Attempt to resize horizontally
3. When stuck, execute ctrl-alt-delete
Actual Results:  
Browser freezes / unfreezes

Expected Results:  
Browser resizes horizontally

This works fine for me. Is this on all pages? And do you see the same in safe-mode / with a new profile?

I have to examine this further to check safe mode (has not been tried yet).

Reporter, are you still seeing this issue with Firefox 3.6.13 or later in safe mode? If not, please close. These links can help you in your testing.

You can also try to reproduce in Firefox 4 Beta 8 or later, there are many improvements in the new version, http://www.mozilla.com/en-US/firefox/all-beta.html
