Firefox developer edition 52.0a2 - won't save changes made to customize toolbar after browser exit
The toolbar gets reverted to default after I restart the browser, no matter what changes I make to customize the toolbar.
I've already tried everything here: https://support.mozilla.org/en-US/kb/changes-toolbars-and-window-sizes-are-not-saved
I've also completely uninstalled firefox, along with the firefox's appdata folder, and installed again (and restarted the computer several times). I've tried running it in admin mode. Nothing appears to fix it. Can't seem to find if this is a known bug or not.
Browser: Firefox developer edition 52.0a2 OS: windows 10 64bit Pro

It could be that one of the extensions is causing this problem.
Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.
- Switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
- Do NOT click the "Refresh Firefox" button on the Safe Mode start window

If it works in Safe Mode and in normal mode with all extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) disabled then try to find which extension is causing the problem by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via *"3-bar" menu button -> Exit (Power button)
- Windows: File -> Exit
- Mac: Firefox -> Quit Firefox
- Linux: File -> Quit

The toolbar customization is normally saved in the browser.uiCustomization.state pref.
Do you see this pref on the on the about:config page?
You can paste its value in the Scratchpad and press "Pretty Print".
When I customize the toolbar, the nav-bar property in browser.uiCustomization.state properly reflects the changes I want.
However after I restart the browser, it reverts back to it's default state.
the value after changes (I.E. the one I want to keep)is:
{

Thanks, it was indeed an add-on - Complete Youtube Saver. They were also aware of it apparently.
Should always start with disabling add-ons when tracking down issues :)
