Bug: Fix excess search.engine.default.changed Glean events recorded for add-on search engines
Status: NEW
Priority: P3
Created: 2024-12-05 16:26:01+00:00
Resolved: 2025-02-26 16:33:59+00:00

We've noticed an excessive number of `search.engine.default.changed` Glean events where the change source is `engine-update` associated with add-on search engines in Nightly (see [these](https://sql.telemetry.mozilla.org/queries/96196/source#237584) [two](https://sql.telemetry.mozilla.org/queries/104246/source) Redash queries). We need to investigate and debug these excess Glean events, especially wrt the DDG and Qwant add-on search engines.

Bug: Since v133.0 (including v135.0.1), Firefox prevents a taskbar in Windows set to autohide from unhiding when maximized
Status: NEW
Priority: P3
Created: 2024-12-06 00:57:27+00:00
Resolved: 2025-02-25 01:32:06+00:00

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:133.0) Gecko/20100101 Firefox/133.0

Steps to reproduce:

No meaningful steps. Firefox has remembered previous setting of starting maximized. When starting Firefox maximized, I am unable to unhide the taskbar using the standard mouseover.

This did not occur in the previous 132 versions and does not appear to occur in any other application including Edge.


Actual results:

When Firefox is maximized, if the taskbar is set to autohide, it does not unhide unless unmaximizing and remaximizing or by forcing the start menu to display with the windows key.


Expected results:

I would expect to mouse over the bottom of the screen and the taskbar to unhide.

2. Hover your mouse over the tab with this image


Actual results:

The text in the tooltip is cut off and incomplete. It doesn't look nice. Screenshot: https://i.imgur.com/P4jlldD.png


Expected results:

Long text in the tooltip should either be cut off nicely with further display of the image resolution, as it is implemented in Chrome, or displayed without cutting, as it is implemented in Safari.

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:133.0) Gecko/20100101 Firefox/133.0

Steps to reproduce:

1. Open new tab (CTRL + T)
2. Open Bookmarks sidebar (CTRL + B)
3. Hover over the sidebar
3. Attempt to scroll through the bookmarks using the mouse wheel


Actual results:

On the right of the sidebar, the bookmark scroll should be displayed


Expected results:

No scrollbar is displayed for bookmarks sidebar.

Additional information:
I noticed this issue occur only if i open the bookmarks sidebar when I'm on the tab without scrollbar. If i open the sidebar when I'm on a page with scrollbar (i.e. reddit), the scrollbar appears just fine for the bookmarks
Bug: hourglass icon sometimes used as tab favicon on session restore
Status: RESOLVED
Priority: P1
Resolution: DUPLICATE
Created: 2024-12-06 10:44:58+00:00
Resolved: 2025-01-31 18:08:54+00:00

Firefox 135.0a1 20241205213207 on Windows 10

Sometimes when Firefox gets launched and session restores, restoring tabs - especially the pinned ones - use a hourglass as icon. This started a few weeks and was consistent or frequent but it is intermittent actually and can also affect tabs which don't have their web content loaded.

The setting `ui.prefersReducedMotion` is not set - the hourglass should not be used as far as I understand.
Bug: A particular PDF file is slow-to-render in Firefox and hence impossible-to-print since it overshoots the print watchdog timer

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:133.0) Gecko/20100101 Firefox/133.0

Steps to reproduce:

I have a large PDF document (included as an attachment to this bug report) opened inside Firefox. I press Ctrl + P to start printing. As a destination I choose "Save to PDF" and click "Save". 


Actual results:

Firefox saves blank PDF - its size is ~1kb. When I open the file I see a white page.


Expected results:

I should see a properly saved document.
Bug: Firefox is NOT set as the default browser even if the “set_default_browser” attribution campaign id is contained by the installer
Status: VERIFIED
Priority: P1
Resolution: FIXED
Created: 2024-12-06 15:21:35+00:00
Resolved: 2024-12-12 12:59:29+00:00

**[Affected versions]:**

- Firefox Developer Edition 134.0b5 (BUILD ID #20241204091850)

**[Affected Platforms]:**

- Windows 10 x64
- Windows 11 x64

**[Prerequisites]:**
- Download the Firefox installer containing the “set_default_browser” attribution campaign id using [this link](https://drive.google.com/file/d/1Xcpjf9W7pkMxQ4p0XRAYJlx_Sr-3TdXL/view?usp=drive_link).

**[Steps to reproduce]:**

1. Install the browser using the installer from the prerequisites.
2. Navigate to the “about:welcome” page and observe the available options on the first screen.
3. Navigate to the “about:preferences” page and check if Firefox is set as default.

**[Expected result]:**

Step 2: The “Set Firefox as default browser” option is not displayed on the first screen of the Onboarding Tour.
Step 3: The Firefox browser is set as default.

**[Actual result]:**

Step 2: The “Set Firefox as default browser” option IS displayed on the first screen of the Onboarding Tour.
Step 3: The Firefox browser is NOT set as default.

**[Notes]:**
- I have verified and can confirm that the “set_default_browser” attribution campaign id is present on the “about: telemetry#search=attribution” page.
- I have also verified that Firefox is NOT set as the default browser on the OS settings page.
- This issue is not reproducible on any Firefox Beta 134.0b1 or later builds if the attribution code is set by modifying the “postSigningData” file to contain the “campaign%3Dset_default_browser” string.

Bug: First navbar toolbar button left / start inline padding missing if the first element is invisible (e.g. vertical-spacer when not using vertical-tabs)
Status: ASSIGNED
Priority: P2
Created: 2024-12-06 16:31:31+00:00
Resolved: 2025-01-07 15:53:14+00:00

Steps to reproduce:

Putting urlbar container as first element using customize toolbar menu.


Actual results:

Urlbar is too close or overlapping the buttons on the right side.


Expected results:

Padding for urlbar should be correct when it's first child element of nav-bar.

The code that creates this issue is on line 394 in browser-shared.css:
"padding-inline-start: var(--toolbar-start-end-padding);"

Setting it to margin-inline-start instead fixes the issue with wrong positioning. I don't know if using margin instead of padding can cause other issues for you.

Perfherder has detected a talos performance regression from push [2111ce34dd4b26fa94b0fb2fdc7896eedcca1750](https://hg.mozilla.org/integration/autoland/pushloghtml?changeset=2111ce34dd4b26fa94b0fb2fdc7896eedcca1750). As author of one of the patches included in that push, we need your help to address this regression.

### Regressions:

| **Ratio** | **Test** | **Platform** | **Options** | **Absolute values (old vs new)** |

Details of the alert can be found in the [alert summary](https://treeherder.mozilla.org/perfherder/alerts?id=42967), including links to graphs and comparisons for each of the affected tests. Please follow our [guide to handling regression bugs](https://wiki.mozilla.org/TestEngineering/Performance/Handling_regression_bugs) and **let us know your plans within 3 business days, or the patch(es) may be backed out** in accordance with our [regression policy](https://www.mozilla.org/en-US/about/governance/policies/regressions/).

If you need the profiling jobs you can trigger them yourself from treeherder job view or ask a sheriff to do that for you.

You can run all of these tests on try with `./mach try perf --alert 42967`

The following [documentation link](https://firefox-source-docs.mozilla.org/testing/perfdocs/mach-try-perf.html#running-alert-tests) provides more information about this command.
