Same in Safe Mode or with new profile?

That's a pretty interesting stack, with FxAccounts, OS.File and Session Restore interleaved by the magic of Promise.jsm. Tim, does the top of the stack sound familiar to you?

This looks like a problem with the tab switcher in tabbrowser.xml, I guess SessionStore doesn't handle exceptions when setting gBrowser.selectedTab very well, that's not something we can account for. Mike knows a lot about that tab switcher I think.

(In reply to David Rajchenbach-Teller [:Yoric] (use "needinfo") from comment #4) > That's a pretty interesting stack, with FxAccounts, OS.File and Session > Restore interleaved by the magic of Promise.jsm. Tim, does the top of the > stack sound familiar to you? ¡Hola David! Does this mean I might get Session Restore to a working state if I disable Sync? ¡Gracias! Alex

Probably not, unfortunately.

There's code in the async tab switcher that's attempting to log information about the tab that's being selected to the console, including the URI. I guess if the currentURI hasn't been set we'll error out. It looks like there's code in remote-browser.xml (and browser.xml) to set the URI of the browser from SessionStore. The comment above it reads: "Used by session restore to ensure that currentURI is set so that switch-to-tab works before the tab is fully restored. This function also invokes onLocationChanged listeners in tabbrowser.xml". I don't actually see that method being called by anything in the tree, however. This was added back in bug 923333, wayyyyy back in 2013... felipe, did something fall through here? Should we be setting the URI in restoreTab or something?

Adding rnewman in case there's insight from the FxAccounts side...

Yeah, thought I needinfo'd felipe. Whoops.

¡Hola Mike! Sent the requested file. I truly hope all content is family friendly but please forgive me otherwise the Web is a wild, wild place and sometimes I have to test things I'm not proud of ;-) ¡Gracias! Alex

Alex - can you try disabling your add-ons for a week to see if this still crops up with them off?

¡Hola Mike! Would give it a try sans add-ons. Funny on today's restart, I found this on "Browser Console" even if the session seemingly restored properly: Could not write session state file TypeError: this.Paths is null Stack trace: Agent.write@resource:///modules/sessionstore/SessionWorker.js:196:9 worker.dispatch@resource:///modules/sessionstore/SessionWorker.js:21:24 anonymous/AbstractWorker.prototype.handleMessage@resource://gre/modules/workers/PromiseWorker.js:122:16 @resource:///modules/sessionstore/SessionWorker.js:30:41 EventListener.handleEvent*@resource:///modules/sessionstore/SessionWorker.js:30:1 Agent.write@resource:///modules/sessionstore/SessionWorker.js:196:9 worker.dispatch@resource:///modules/sessionstore/SessionWorker.js:21:24 anonymous/AbstractWorker.prototype.handleMessage@resource://gre/modules/workers/PromiseWorker.js:122:16 @resource:///modules/sessionstore/SessionWorker.js:30:41 EventListener.handleEvent*@resource:///modules/sessionstore/SessionWorker.js:30:1 SessionFile.jsm:299 Does this mean something to you? ¡Gracias!

If I had to say, it looks like the SessionWriter.js is attempting to write without having been properly initialized. Is there anything else in your Browser Console about SessionWorker.js?

The messages of comment 27 are unrelated to Session Restore.

alex_mayorga, Alright, let's try something slightly different. Can you please do the following: 1) Enable the Browser Toolbox (follow these steps): http://screencast.com/t/fBpGhGgqwQV 2) Next time you restart and you see no content in your tabs, go to the Developer Tools button, and choose to open the Browser CONTENT Toolbox (_not_ the Browser Toolbox). 3) When the Browser Content Toolbox opens, switch to the console tab. Anything in there worth reporting?

¡Hola Mike! So today after a laptop reboot App Tabs did came back but the only regular that came back was blank and titled "New Tab" but it did not have tiles nor the "Restore Previous Session" button, just a white wasteland. Please find below what I managed to capture form the "Content Toolbox". Hope it helps. ¡Gracias!

FWIW after the initial all white "New Tab" scare "Hamburger" > "History" > "Restore Previous Session" did get me back my tabs =)

Nothing in alex_mayorga's log in comment 30 is much use either. :/ Well shoot. How do we reproduce this? Out of curiosity, alex_mayorga - browser.sessionstore.restore_on_demand is set to true, correct? And you're still seeing this with a very recent (as in, post Nov 24th) Nightly?

¡Hola Mike! Yup! browser.sessionstore.restore_on_demand;true Found browser.sessionstore.debug and set it to true, hopefully this would yield some useful data next time this happens... Where would this debug be logged to? Browser Console? Any other debug preferences that might help to capture more information? ¡Gracias!

Best to set browser.sessionstore.debug to false - that's not for debugging SessionStore at run time for end-users, but to put SessionStore into a special state for our automated tests. Are you familiar at all with the Browser Toolbox? Have you ever built your own Nightly before? If so, I might be able to walk you through some local debugging steps over a video chat or something if we have some common free time.

Shoot me a doodle if you think it might be fruitful regardless. I've reverted browser.sessionstore.debug to false. ¡Gracias!

Okay, sent you a Doodle invitation. Let's see what we can figure out.

¡Hola Mike! I put some options into the Doodle. FWIW, could you please check https://bugzilla.mozilla.org/show_bug.cgi?id=1123464#c11 in case it is related. About to "Restart Nightly to apply updates" for today, please ping me on IRC #firefox or #qa and let me know if you need me to collect anything. ¡Gracias!

Hey alex_mayorga, Let's go with the Friday option. I'll find and ping you in IRC at that time slot. I'll hopefully have some builds for you to try. Thanks!

¡Hola Mike! This is the log from mayorga-logging-again.zip It had the dreaded blank "New Tab" on startup but was able to get back my session with "Hamburger" > "History" > "Restore Previous Session". Please let me know if you need more data or anything. ¡Gracias!

Are you still seeing this alex_mayorga?

¡Hola Mike! As of recently I do see the about:sessionrestore but that tab crashes as mentioned at https://bugzilla.mozilla.org/show_bug.cgi?id=1116884#c101 Is that a variant of this? I'll keep and eye out for this next week so not clearing the n? ¡Gracias!

I don't think that's a variant, no. What I think you were experiencing in this bug is a foul-up during a mostly successful session restore. Seeing about:sessionrestore means that a session restore failed.

This might be bug 1243549, which has a patch.

Clearing needinfo until bug 1243549 can be tested (which is being tracked in that bug)

Hey alex_mayorga, I never heard about whether or not bug 1243549 landing made this stop happening. I'm going to close this INCOMPLETE for now. Please re-open if you still see this.

This is with a very up-to-date Nightly? I know some work landed recently to make writing to SessionFile more robust. As for finding your previous session, it might be in your profile folder. Do you have anything in your sessionstore-backups in your profile folder?

That's interesting - because it looks like at least some pages are being loaded (portal.office.com for example) - did _some_ pages load, like in app tabs?

¡Hola Mike! IIRC "App Tabs" loaded, but the one tab where the "Restore my previous session" button would have been did not. Unfortunately I can't make this bug appear at will, but it is still out there in some shape or form =( What do I gather next time it happens? ¡Gracias! Alex

Taking this out of m9 because it does not seem to be a very common ( no dupes, for example ). I personally ran into something similar last fall but have not seen it recently.

we need concrete str or more reports before we can act on this.

I've had zero luck reproducing this bug despite putting my machine in as close a configuration as possible to alex_mayorga's. I think we're going to have to go back to basics, which means I start sending alex_mayorga more instrumented builds with logging. I should be back on my good-for-building Windows machine on Thursday, so I'll provide one then.

¡Hola Mike! The dreaded blank "New Tab" is back again today on Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:48.0) Gecko/20100101 Firefox/48.0 ID:20160328030215 CSet: 63be002b4a803df1122823841ef7633b7561d873 What shall I capture from the affected session? ¡Gracias! Alex
