After the recent update of Firefox Browser to version 31.0 I noticed empty space at the bottom of the page whenever I open a new window (not a new tab) and as usual asked on IRC and then filed a bug here.
I was then suggested to restart Firefox in safe mode by disabling all the add-ons. To do so follow the steps here.
I also tested it under a different profile (in my case a new profile). To create a new profile follow the steps here.
In both of the above troubleshooting method I was unable to reproduce the bug. So I could easily conclude that there was some compatibility issue with add-on and the updated version of Firefox as same kind of issues were reported on bugzilla few years back. As it was all resolved I had to report a new bug.
If you want to skip all the above methods, then follow these steps:
- Goto Tools->Add-Ons (or Press ⇧+⌘+A).
- Select Extensions.
- Disable one plugin at a time (Restart browser if required).
- Open up a new window (⌘+N).
- If the empty space if still there then repeat steps 3 to 5
When you find the extension that is causing the issue you can keep that one disabled and enable the other plugins that you disabled and continue using Firefox normally.
Let the Windows be open, and feel the Freedom.
