1335653 - When ONE tab crashes, Firefox reloads ALL tabs

Status: RESOLVED INCOMPLETE

(Firefox :: Untriaged, defect)

Description

[Szczepan Hołyszewski]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:51.0) Gecko/20100101 Firefox/51.0
Build ID: 20170126200443

Steps to reproduce:

Anything that causes a single tab to crash.


Actual results:

All tabs went blank and each of them subsequently reloaded when activated.


Expected results:

Only the crashed tab should be affected - isn't that the whole point of e10s? As it works now, there is no *practical* difference between current behavior and the browser crashing as a whole.

Are you sure e10s is enabled in about:support (line "Multiprocess windows")?

Comment 2

[Szczepan Hołyszewski]

There is no "Multiprocess windows" line. The "Multi-process staged rollout" is present, at version 1.7 and enabled.

Please add some steps to reproduce this, I tested this on Ubuntu 16.04 with FF release 51 and FF 54.0a1(2017-02-05), ussing a add-on that is created for reproduce crashes, and I can't reproduce this issue. In my case everything works as expected. 

If I write in URL bar about:support   ->      Multiprocess Windows 	1/1 (Enabled by default)

You should see a "Multiprocess Windows" line.

[Szczepan Hołyszewski]

Ah, I'm sorry. I Ctrl+F'd for the exact string "Multiprocess Windows" but that part of the about:support page is actually translated so I should have been looking for "Okna wieloprocesowe". It says 1/1 but enabled by user, not by default.

Also maybe I was imprecise in my description. When a tab crashes, other tabs are of course not immediately REloaded, they are however UNloaded (blanked) and then each of them reloads once activated.

Hi,
Marking this as Resolved: Incomplete due to the lack of response from Szczepan Holyszewski.
If the issue is still reproducible with the latest Firefox version, feel free to reopen the bug with more information.

Where can I find the "add on that is created to reproduce crashes"?

Here is the add-on http://ted.mielczarek.org/mozilla/crashme.html, but first before you install the add-on I need to tell you to create a new profile and go to about:config and search after xpinstall.signatures.required and switch the pref to false in order to be able to install the add-on. After every crash please write in the crash report "Test" to know that this is a test. Also please use this only for testing this issue and create a new profile.
