screenshot of problem

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:37.0) Gecko/20100101 Firefox/37.0
Build ID: 20150402191859

Steps to reproduce:

click the three lines for options
click 'customize'
wait a couple of seconds for it to load

Actual results:

the "customize Firefox" becomes large and extends beyond the monitor even on high resolutions, on all computers. with no scroll bar, moving tool buttons and other buttons, and addon buttons to where you want them is NOT possible

Expected results:

the "customize Firefox" should stay within the range of the monitor after the couple of seconds it takes to load so you can move things where you want them or remove things that are out of reach and/or in odd spots or at least provide a scroll bar

Does the problem still happen if you start Firefox in Safe Mode? (Safe Mode disables extensions and themes, hardware acceleration and some JavaScript stuff in order to exclude some possible reasons for problems. It does not disable plugins which are add-ons.) See 

And does this also happen with a new and empty profile? See and

Hi Moltres, Can you still reproduce this issue in Firefox 42.0?

I tried duplicating this issue on Windows 10 x64 with a resolution of 1366 X 768 using below mentioned FireFox version but could not reproduce it. Attached is the screenshot from my computer.

Name 	        Firefox
Version 	42.0
Build ID 	20151029151421
User Agent 	Mozilla/5.0 (Windows NT 10.0; WOW64; rv:42.0) Gecko/20100101 Firefox/42.0

It would be great if you could try again after updating Firefox to version 42.0 and let us know if you still encounter the same issue.

Resolved-Incomplete due to time since last communication/update by reporter.
Please feel free to reopen if the error occurs in a current Firefox version.
