Bug: [MSIX] Extra icon added to the taskbar when pinning to taskbar
Status: VERIFIED
Priority: --
Resolution: FIXED
Created: 2024-09-06 09:51:25+00:00
Resolved: 2024-10-14 20:13:46+00:00

**Found in**
* Firefox 131.0b2

**Affected versions**
* Firefox 131.0b2
* Latest Nightly 132.0a1

**Tested platforms**
* Affected platforms: Windows 10, Windows 11
* Unaffected platforms: macOS 13.6, Ubuntu 22.04

**Steps to reproduce**
1. Install Firefox >=131 MSIX build which has the fix from bug 1794159
2. Start the browser and visit `about:welcome` (if not already open at start)
3. Select `Pin Firefox to task bar and start menu` and uncheck the rest (just for simplicity)
4. Click Save and continue and Yes on the Windows notification.

**Expected result**
* The Firefox icon that's already opened is pinned and when closing the browser and clicking the pinned icon from taskbar there is only one Firefox icon displayed in the taskbar.

**Actual result**
* A new icon of Firefox browser is added to the taskbar along with the already existing one (if the browser is already opened) and clicking on the pinned icon when Firefox browser is closed will open a second Firefox icon in the taskbar.

**Regression range**
* Not a regression since this is a new implementation for MSIX builds in bug 1794159.

Bug: Firefox does not set itself as default browser if installed its path contains spaces
Status: NEW
Priority: P3
Created: 2024-09-06 14:59:49+00:00
Resolved: 2024-11-20 03:12:52+00:00

With a tar.bz2-installation on gnome its not possible to configure Firefox as default browser if the path name contains spaces.

Steps to reproduce:

- Extract the archive to a folder with a space in its name
- run Firefox
- visit `about:preferences` and try to set it as default browser (*does not work, sad smiley*)

The console displays an error message of type `NS_ERROR_FILE_NOT_FOUND` in [`setDefaultBrowser`](https://searchfox.org/mozilla-central/rev/cc01f11adfacca9cd44a75fd140d2fdd8f9a48d4/browser/components/shell/ShellService.sys.mjs#345-367)

Bug: DND should show busy dialog for entire multi-part scan
Status: RESOLVED
Priority: --
Resolution: DUPLICATE
Created: 2024-09-06 19:21:55+00:00
Resolved: 2024-10-07 17:41:52+00:00

The approach to DND scanning submits concurrent analysis requests to the DLP agent.  Currently, only the first one gets a "busy DLP" dialog, although the results of the drop won't show until and unless the DLP grants permission.  So there is a pause, during which the page is active, between the agent's first response (of a multi-part response) and the drop event being sent to the web page.  The fix is to change [MapByTopBrowsingContext](https://searchfox.org/mozilla-central/rev/90dc3743ea284c258148124dc54dfd123e82586f/browser/components/contentanalysis/content/ContentAnalysis.sys.mjs#62) from being a map of `BrowsingContext`s to `nsIContentAnalysisRequest`s, to being a map of `BrowsingContext`s to lists of `nsIContentAnalysisRequest`s.  Also changing the places that call `deleteEntry` to add a view for "the first" remaining request in the `nsIContentAnalysisRequest` list (if there are any), after it calls `_disconnectFromView`.
Bug: Synced tabs in the Synced tabs menu are not showing close remote tab feature or inactive tabs due to overflow
Status: RESOLVED

Resolution: FIXED
Created: 2024-09-06 19:54:45+00:00
Resolved: 2024-09-10 21:07:11+00:00


Steps to reproduce:
1. Right click toolbar -> Add synced tabs icon to the toolbar 
2. Click it to view synced tabs

Expected:
 - To see synced tabs look like the avatar and hamburger menu

Actual:
Menu overflows (see attached screenshot) and we do not see the the close remote tab dismiss button or the right arrow for inactive tabs.

This button most likely uses subtly different styling here and should be updated. This happens on Nightly and Beta.

Bug: Session corrupted: most tab state gone, url moved to userTypedValue
Status: NEW
Priority: P3
Created: 2024-09-07 17:02:28+00:00
Resolved: 2024-09-09 15:59:15+00:00

I witnessed a user losing most of their tabs state on macOS, after failing to update from Firefox 127 to 129.0.2 on 28 august 2024 (when 129.0.2 was the latest version). The update failed because elevated permissions were required to install the component necessary to update Firefox. Upon failing to update, Firefox restarted with the original (old) version. This happened a few of times, and at some point a bug got triggered that resulted in the loss of most tab state. Completing the upgrade by granting elevated access did not resolve the issue.

I extracted the bare minimum from the user profile (of which I still have a full copy) to reproduce the issue.

STR:

1. Create a directory, "profdir".
2. Put the attached `sessionstore.jsonlz4` in that directory.
3. Launch Firefox with that profile. E.g. `/Applications/Firefox.app/Contents/MacOS/firefox -profile profdir` on macOS, or `firefox -profile profdir` on Linux.
4. In the first about:sessionrestore tab ("Restore Session"), choose to restore all tabs (or at least the first window).

Expected:
- All tabs should be restored with their URLs and titles, and any other relevant state.

Actual:
- The restored session looks incomplete:
- The focused tab (tab 7) has title "New Tab" and displays a URL without rendering any content. The displayed URL is actually the "userTypedValue" from the session restore file. If the user interacts with the location bar and presses Esc, the URL disappears.
- Several tabs from tab 9 onwards until the "What's new in Firefox" tab have no tab titles. Upon focusing them a typed URL appears, similar to above.

Additional information:
- The session restore file has 2 "What's new in Firefox" tabs, seemingly suggesting 125.0.2 -> 127.0 and 126.0 -> 129.0.2 upgrades. I witnessed the version to be 127.0 at some point before the update succeeded.

  - https://www.mozilla.org/en-GB/firefox/129.0.2/whatsnew/?oldversion=126.0&utm_medium=firefox-desktop&utm_source=update&utm_campaign=129
- This Firefox instance is on the regular release channel. The bug happened while 129.0.2 was the latest version, a few days before the 130.0 release.

Bug: New tab page briefly renders with each tile being a small-height "sausage", before tiles expand to actual full content-height
Status: VERIFIED
Priority: --

STR A:
1. Open or refresh a new-tab, and watch very carefully.

OR, more aggressive STR B (making issue easier to see):
1. While viewing a new-tab page, hold Ctrl+R (or Cmd+R on mac) to make the page repeatedly reload as fast as it can.

ACTUAL RESULTS:
You can see a brief rendering during pageload, where a placeholder "skeleton-layout" for the "Thought Provoking Stories" tiles  -- and the tiles are **all visible in the viewport, all with barely any height at all**. Loosely speaking, this looks like we've got 24 empty sausage shapes filling the page (3 columns of 8), before we populate and grow them to actual tiles, at which point only the first 3 remain in view.

EXPECTED RESULTS:
A skeleton layout that looks closer to the final sizing/rendering.

This is a recent-ish regression, from bug 1914874, based on my mozregression testing. Before that bug's commit, the STR would produce a taller "Skeleton UI" template with actual (blank) tiles, rather than sausage shapes, which makes the page load changes look less odd as content populates.

Here's a performance profile showing the issue, zoomed in on one reload operation (using STR A, just a simple single reload of a new tab): https://share.firefox.dev/3XbWxRq
In the middle of that profile, you can see the bad "sausages" rendering in the middle, from t=7.31s to t=7.34s.

When you have enough pinned tabs that it spans 3 rows (for me, if I have more than 12), trying to reorder a pinned tab within this group is tricky:
- while dragging, the grid shifts
- dragging and moving the tab around, the tab can't be inserted between 2 tabs of the same row, it only seems possible to add it on a new "row", at the first position

STR:
1. Start with `sidebar.revamp = true`.
2. Click the sidebar toggle button in the toolbar several times (does not require spamming).

Expected:
Animation transitions between states smoothly with no flashing or flickering.

Actual:
Final expanded state sometimes flashes before expansion animation starts. Collapse animation is unaffected.

Happens on Windows 11 and Ubuntu 24.04.

**Steps to Reproduce**
1. From Firefox Labs, enable Sidebar and Vertical tabs.
2. Open enough tabs to make the container overflow.
3. Pin some tabs.

**Expected Result**
The (top) divider for pinned tabs matches styling of the (bottom) divider for vertical tabs.

**Actual Result**
The divider for vertical tabs has uneven padding on both sides, and does not match pinned tabs styling.
