So I have enabled the photon structure preference. Is it expected that when you are customizing the toolbars and the new overflow panel that in order to exit customization you close the tab? There doesn't appear to be an "Exit Customization" button.

that Exit Button IMO isnt needed anyway so perhaps they might have gotten rid of that , you might find your answer by looking through the Nightly Blog link in the first post

Can't reproduce the issues on the Kingdom Come board. Not on my i7 6700k, not on my i5 6200U.
The russian site has some jank while reloading a new article with the i5 6200U, Chrome is smoother there.

Just updated to 55.0a1 (2017-05-15) (64-bit).

Glitch: All extensions are now force-enabled on my side, despite being marked as disabled in about:addons. The disable state of extensions is disregarded.

**Correction**: I should not have said "all", rather "some". NoScript and Greasemonkey are enabled despite being disabled in about:addons.

[GHM113]

Something strange is going on with addons in Nightly 15-05-17. What I had in nightly 14-05-17:
uBO, Session Manager, Tab Mix Plus, NoScript enabled; Yet another smooth scrolling disabled

What I got in 15-05-17:
All addons marked as disabled in about:addons but
uBO and Session Manager disabled
Tab Mix Plus and Noscript enabled
YASS also enabled even though I didn't turn it on manually and it is marked as turned off in about:addons

So it looks like all jetpack addons got disabled and all XUL addons enabled and about:config is broken on top of that

@ gorhill & GHM113 - I can confirm this, and I reported this here - Bug 1364878 - All extensions are force enabled and marked as disabled in about:addons & about:support in Mozilla Firefox Nightly 55.0a1 (2017-05-15)

Thank you very much! You are my savior!

Thank you very much for developing and supporting uBlock Origin, the one and only high performance adblocker! I launched Firefox Release with AdBlock installed and was horrified how slow the browser was.

Thank you very much! I hope to upgrade to 6-core Coffee Lake and GV104. That should be enough for Nightly.

You close the tab to exit customize.

FYI - Classic and Dusk themes were removed from Bugzilla...

[GHM113]

It would be great to have some kind of built-in downgrade mechanism that installs the previous version of Nightly

FYI - Classic and Dusk themes were removed from Bugzilla...

yep, default theme text is low contrast for me. I prefer classic.

Today win32 build is incredibly messed up. It shows all extensions to be disabled, yet even ones that were actually disabled before were actually loaded...
Apart from this everything was broken on the UI.

[avada]

Also the the back/forward button seems to be broken, even after removing relevant addons. But that happens with yesterdays build too. I don't know what to make of it.

What's wrong with back and forward? Seems to be ok here using a 64-bit build.
