1095730 - [e10s] First tab in a restored window never gets its title

Status: RESOLVED WORKSFORME

(Firefox :: Tabbed Browser, defect)

Description

[Richard Newman [:rnewman]]

Just noticed this after switching Vertical Tabs back on. I don't think it's VT related.

After a session restore, the first page has been restored (if not loaded), but its tab is still titled "New Tab". Clicking the tab causes it to load and the title to come back. One of my windows actually had the first tab selected, and the page was loaded, but the title was "New Tab" until I reloaded the page.

Yes, unless you ended up with a genuinely empty tab. Mine knew which page to show.

Maybe it's not the same bug then since mine was blank with empty content in it

Is there a good way to reproduce this? WFM all the time.

If I had to speculate:

* Open nine windows with approximately 10-30 tabs per window. Load content in each. With e10s disabled your RSIZE should be about 1.5GB-2GB.
* Install Darrin's Vertical Tabs add-on. (Who knows, it might make a difference.)
* Relaunch with e10s enabled.
* Wait a few minutes for session restore to finish.
* Quit and relaunch again.
* Observe symptoms in Comment 0.

Can you try without that addon?

I think someone other than me (probably a developer working on e10s) needs to try to repro this with those steps; I had to turn e10s off after filing a bunch of bugs because I don't have time to work around them, and I don't want to keep tempting the gods of session store data loss.

I still can observe the same behavior even with addon disabled Brad

This works for me and everyone else on the e10s team. If you still see this, please provide exact STR that doesn't include an add-on.
