- Open at least 4 tabs
- On the fourth tab open a website from the "Top Sites" section

Case 2:
- Open a new window
- Open at least 12 tabs
- Continue to open new tabs


Actual results:

In case 1 the window buttons disappear and stay hidden until the mouse is hovered over the window buttons or an inactive tab, or until a new tab is opened.

Expected results:

In either case the window buttons should be permanently visible.

Can you please attach a screenshot of that? Also, can you please check with clean (new) profile? I can reproduce that with latest nightly but maybe I do something wrong.

I just discovered that resizing the window results in the same behaviour.

Videos created with a fresh Firefox profile.
I also uploaded the clips to Imgur, because I'm unable to open the attachments in Firefox: https://imgur.com/a/GIrNq

There appear to be two different sets of window buttons, due to the regression with bug 1443481.

I assume you meant to write "can't"?
The above videos were made with build 20180304220118
I just updated to the latest build and the problem is *not* present.

Yes, sorry.

I see. I also don't see that. Closing now, please reopen if it appears again.
