[Affected versions]: Firefox 55.0a1 (Build Id:20170505030252) [Unaffected versions]: Firefox 54.0b4 (Build Id:20170501133120) Firefox 53.0 (Build Id:20170413192749) [Affected platforms]: Windows 10 64bit Mac 10.11.6 Ubuntu 16.04 64bit [Steps to reproduce]: 1.Launch Firefox with a clean profile. 2.Enable e10s (if it is not already enabled). 3.Access the https://www.youtube.com/ webpage. 4.Open several videos in new tabs. 5.Restart Firefox. 6.Reload all Tabs (without focusing them). 7.Focus the opened tabs. 8.Observe that the content is not displayed. [Expected result]: Content is displayed after reloading all tabs. [Actual result]: No content is displayed. [Regression range]: This is a regression: Last good revision: f77767c9f2bcc78addef282be397ac869cb3dca8 First bad revision: fb4fca2b150a3715192e60e4dde593052fb563e2 Pushlog: https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=f77767c9f2bcc78addef282be397ac869cb3dca8&tochange=fb4fca2b150a3715192e60e4dde593052fb563e2 It seems that bug 1353060 may have caused this issue. [Additional Notes] Please note that the content is not displayed even if refreshing the tab. It seems that this issue is not reproducible while having e10s disabled. For further information regarding this issue, please observe the attached video.
Hi Kris! Can you please have a look? Thanks !

I think it is time to backing the offending bug(bug 1353060) out
Severity: critical → blocker
(In reply to Alice0775 White from comment #5) > I think it is time to backing the offending bug(bug 1353060) out It is definitely not. This only happens when extensions do something they should not be doing (reload a tab that hasn't been initialized yet). If it's not fixed before the merge, we can consider backing out.

I mean extensions. Hm. I didn't realize we had a Reload All Tabs feature with not extensions installed. That almost certainly should not be touching uninitialized tabs.

It doesn't help that the comment says "we only want to reset permissions on user reload" and "reload all tabs" is in fact a user action. Pretty obscure stuff.

Kris, how important is this bug? Something we wanna land in 55, or uplift in early beta? Or can it wait for 56?
Flags: needinfo?(kmaglione+bmo)
The patches for bug 1362462 have fixed the immediate regression, but our behavior in this circumstance is still pretty flaky, so I think we should fix this in 55 regardless. I'll try to have an updated patch later today.

Moving to Firefox:TabbedBrowser which seems a better fit for this issue.

Dão, not sure if this is something you can help with (as it is now in "your" component or if Kris is still planning on a patch for 56/55.

Hi everyone ! It seems that I can't reproduce this issue anymore. This issue was fixed by another patch: First good revision: 63cc19a2300f356abf1fa03884a9ac3d4792ef57 Last bad revision: 72a455b224e63335c4cf6cce7588d2b9c9de7a5f Pushlog: https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=72a455b224e63335c4cf6cce7588d2b9c9de7a5f&tochange=63cc19a2300f356abf1fa03884a9ac3d4792ef57 Looks like the following bug has the changes which introduced the fix: https://bugzilla.mozilla.org/show_bug.cgi?id=1362462

I don't know what Kris is planning, his needinfo request is still pending. But based on comment 12, it seems that we don't need to track this for 55 anymore.

This may be a duplicate of bug 1362462. I'll continue discussion there.
