Firefox 38.0.1 Window Resize with menubar problem
After update to 38.0.1 I have the menu toolbar enabled and I have a problem with the firefox window changing size when viewing pages. The whole window jitters then I lose the menu bar at the top of the tab bar. at this point I cannot click or enter data into a web page. If I select the border of the window and resize or move the window returns to its original size with the menu bar and tabs correctly displayed.
I also have Firefox developer v 40.a02 this was OK last week I was updated on 29/05 and now also has the same problem.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
- Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
- Do NOT click the Reset button on the Safe Mode start window

You can try to disable hardware acceleration in Firefox.
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
You need to close and restart Firefox after toggling this setting.
