Bug: [Windows] Close Shortcuts doesn't offer close modal dialog with browser.tabs.warnOnClose = true
Status: VERIFIED
Priority: P1
Resolution: FIXED
Created: 2021-09-24 10:33:38+00:00
Resolved: 2021-10-25 12:15:20+00:00

##### [Description:]
While "Confirm while closing multiple tabs" is enabled, shortcuts should display close confirmation. 

##### [Environment:]
Windows 10


##### [Steps:]
1. New profile, about:preferences#general, enable "Confirm while closing multiple tabs".
2. Ctrl+T open several new tabs.
3. Access File/Exit.
3'. Use shortcut for File/Exit - Ctrl+Shift+Q
~~3". Use Alt+F4~~

##### [Actual Result:]
3. Close confirmation is displayed.
3'. Browser just quits, no confirmation is displayed.
~~3''. Browser just quits, no confirmation is displayed.~~

##### [Expected Result:]
The behavior of the Ctrl+Shift+Q shortcut, the File menu and Alt+F4 need to be aligned and to my understanding while the  "Confirm while closing multiple tabs" is selected (non-default 94 option), the user should get the modal close warning.

##### [Regression Range:]
N/A - new feature
Bug: Playing videos uses all memory available and causes Macbook to freeze
Status: RESOLVED
Priority: --
Resolution: DUPLICATE
Created: 2021-09-24 13:20:41+00:00
Resolved: 2021-09-24 13:29:04+00:00

It started happening in the last 24-48 hours. While watching videos on YT, I had to forcefully shutdown my Macbook 13 because it became completely unresponsive. The evening before I managed to kill Firefox before that happened (memory had a process using 85GB of memory at that point).

Nightly 20210923214525 on macOS 11.6 (20G165), Macbook just restarted, and playing the first video over YT.

After only a few minutes, in about:process I see a `Data Decoder` process growing way too quick. In macOS monitoring I see a process (`Firefox NightlyCP RDD Process`), whose memory usage grows about 0.01GB/s

This is the profile of the process from about:processes

Bug: iframe with srcdoc sometimes prefers cached srcdoc over fresh srcdoc
Status: NEW
Priority: --
Created: 2021-09-25 13:33:24+00:00
Resolved: 2021-10-13 12:12:18+00:00

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0

Steps to reproduce:

Load a page that sends `Cache-Control: no-store` as a header and has an iframe with the `srcdoc` attribute. Then either close and reopen the tab, click a link on the page and navigate back to it, or navigate back and forwards.


Actual results:

The page is reloaded but the content of the iframe is the same as before.

If there is an additional iframe on the reloaded page then the one that appears first in the document will always be the one that shows the cached content.


Expected results:

On page reload the iframes should have always shown what was provided in `srcdoc` on that request instead of a previous request. An iframe `srcdoc` should not be cached if its parent document is not being cached.

Bug: Firefox 92.0.1 (64 bit) menu language bug?
Status: RESOLVED
Priority: --
Resolution: DUPLICATE
Created: 2021-09-26 13:26:52+00:00
Resolved: 2021-10-09 14:25:25+00:00

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:92.0) Gecko/20100101 Firefox/92.0

Steps to reproduce:

My OS is Windows 10 (64 bit, 20H2). At the last update of Firefox I noticed that when I start it initially, and also when I open each new window, the regional language settings are not remembered, and the language automatically switches to English. Through trial and error, I found that when I entered in "Customise Toolbar..." (even without changing anything), the browser "remembers" the regional settings and switches to them again (I made a short video where you can see this). I wonder if anyone else has the same problem ...  


Actual results:

(see the attached video)

Bug: Resources fail to load on related tabs when other tabs are closed when loading
Status: RESOLVED
Priority: --
Resolution: INCOMPLETE
Created: 2021-09-27 15:02:51+00:00

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

1. Create a folder of like 20 bookmarks all pointing to the same domain, just different subpages.
2. Open them all in tabs.
3. While they are loading, quickly close first several tabs.



Actual results:

Chances are the pages loaded in next tabs won't have some resources loaded. Especially CSS files.

It looks like the resources were shared between all tabs, and because a tab that was loading them was closed, the loading process stopped. But it was still needed by other tabs!


Expected results:

All resources loaded properly for still open tabs.
Bug: The area of view (scroll point) of the page does not move up to the highlighted element (in certain situations)

**Note**
* When the user navigates through the browser's settings using the tab key and presses SPACE key when focusing a link, he will notice that the point of view moves down (as intended). Next, if he taps the TAB key to move the highlight to the next element, he will notice that the highlight moves (screen reader confirms this), but the screen does not move back up to show the element that is highlighted.

**Affected versions**
* Nightly v94.0a1

**Affected platforms**
* Ubuntu20
* unknown on the other OSes

**Steps to reproduce**
1. Launch browser (and ORCA Screen Reader for confirmation that the focus moves to the next element in the last step).
2. Press ALT, then RIGHT ARROW key, then DOWN ARROW key several times to reach the "Settings" button, then ENTER key.
Notice: General tab of the Settings page is displayed and the Search field is in focus.
3. Press the TAB key until reaching the "Learn more" link from the "Enable Container Tabs" checkbox.
4. Press the SPACE key.
Notice: The page is scrolled down to the next area (below the one in view).
5. Press the TAB key again.

**Expected result**
* The next controllable element on the page is being highlighted (ORCA Screen Reader reads the button) AND the page is scrolled back up to show the highlighted element.

**Actual result**
* The next controllable element on the page is being highlighted (ORCA Screen Reader reads the button), BUT the page is NOT scrolled back up to show the highlighted element.

**Regression range**
* Appears to be an old regression; This is the last important message before giving the generic "not enough data to bisect" error:
2021-09-27T20:38:11.971000: INFO : Narrowed nightly regression window from [2017-07-26, 2017-07-30] (4 days) to [2017-07-28, 2017-07-30] (2 days) (~1 steps left)

**Additional notes**
* This issue occurs in more situations, but it is still quite an edge case.
Bug: browser.tabs.warnOnClose default value is listed as userset in config for the first session after update
Status: RESOLVED
Priority: --
Resolution: WONTFIX

Resolved: 2021-09-27 15:33:07+00:00

##### [Description:]
Upgrading from a non-default vaue for browser.tabs.warnOnClose (false) to default value for browser.tabs.warnOnClose (false) on Fx94 will show the preference as userset until the first restart.

##### [Environment:]
Windows 10 /Mac 11

##### [Steps:]
1. Install an older version of Firefox (Nightly92).
2. Open about:config and switch the value for browser.tabs.warnOnClose from true(default on 92) to false(userset on 92)
3. Upgrade: Nightly92 to Nightly94
4. Open about:config and check the value for browser.tabs.warnOnClose.

##### [Actual Result:]
Although default value for browser.tabs.warnOnClose on Fx94 is False, it is shown as userset (bold)

##### [Expected Result:]
The value on Fx94 should be shown as default, not shown as userset.

##### [Note:]
Since after the first restart the config shows the right type of value,  this is more from the NIT category. Unless it's a config glitch, maybe this issue could affect any Normandy interactions, if any, for the first run after update.

##### [Regression Range:]
N/A - new feature
