Bug 1588386 - Restore toolbars when fullscreen mode exits due to a tab close.
47 bytes, text/x-phabricator-request
pascalc
: approval-mozilla-beta+
Details | Review

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:71.0) Gecko/20100101 Firefox/71.0

Steps to reproduce:

  1. install vimium-ff (amo: https://addons.mozilla.org/firefox/addon/vimium-ff/ source: https://github.com/philc/vimium)
  2. open YouTube to watch a video
  3. go to fullscreen
  4. press 'x' to close current tab

Actual results:

The browser is in a strange state that the tabbar, urlbar and bookmark bar is not visible / usable. Switching to next / prev tabs using Ctrl + PgDn / PgUp does work.

Expected results:

When a fullscreen tab is closed by extension, Firefox should exit fullscreen correctly.

I get a 404 error when running mozregression:

This happens on another video site too. Closing using Ctrl-w does work as expected.

BTW, to recover from this state, one can open the page again (by ctrl-shift-t or using the command line and navigate to some video page), enter fullscreen mode and then exit (by pressing esc), and then things are back to normal.

Thanks YF, I will have a look at this.

More minimal STR (not requiring an add-on):

  1. Visit any YouTube video
  2. Fullscreen the video
  3. Hit Ctrl-W to close the tab

ER:

Fullscreen exits as the tab closes.

AR:

Fullscreen exits, but the browser still has hidden chrome, so the toolbars are all missing.

Thanks Mike! Your STR might not work on Linux though as mentioned in comment 1.

Any updates on this bug, Abdoulaye? Do you think you'll have time to fix it, or should we hand it off? The pressure is on a little bit because we're already almost a week into Beta. :/

Flags: needinfo?(ablayelyfondou)

Hey Mike! Sorry, I've been pretty packed lastly but now I have more time to work on it. I am sure you will see some updates very soon.

Flags: needinfo?(ablayelyfondou)

Hey abdoulaye - just tracking the progress here - is the patch at the state where you need re-review, or are you working on a new revision?

Flags: needinfo?(ablayelyfondou)

Yeah, It just need a re-review here from smaug specially, I am not sure though if he got my new comment. So I will NI him here.

Flags: needinfo?(ablayelyfondou) → needinfo?(bugs)

Given the impact and the number of duplicates that show how easy to get into this state, we can't ship 71 with this bug so I am marking it as a blocker. We will need an uplift to beta and manual QA on the fix.

This can land now.

This can land now.

The new way to request checkin needed is to add the tag Check-in needed to the phabricator revision.

QA Whiteboard: [qa-triaged]

I tested this issue on Ubuntu 16.04, Windows 10 and Mac OS X 10.14 with FF Nightly 72 (2019-11-04) and I can't reproduce the issue. However I also tested a FF Nightly 71 in order to try to reproduce the issue, on the same OSes, but I wasn't able to do it, I used both scenarios from comment 0 and comment 4.
lilydjwg can you please confirm if the issue is fixed on your end on FF Nightly 72.0a1? You can download it from here: https://www.mozilla.org/en-US/firefox/channel/desktop/#nightly

Flags: needinfo?(lilydjwg)

Yes, this issue no longer happens to me with recent nightly (currently 2019-10-31).

Flags: needinfo?(lilydjwg)

Thanks for the info, based on comment 27 and 28 I will mark this as verified fixed.

status-firefox72: fixed → verified

Thanks for fixing this. I don't see the problem in Nightly 72.0a1 (2019-11-04) (64-bit)
