Bug: urlbar page action icons missing

Steps to reproduce:

Actual results:

The page action icons in urlbar is missing: there is only the three-dot icon, and sometimes the reader mode icon appears. But no other icons. Clicking on the three-dot icon I see an empty popup.


Expected results:

I remember there should be a few icons by default, and in my daily use I have some more icons added by addons.

This starts to happen recently and often but not always. Sometimes those icons appear without problems. This happens with a newly-created profile but doesn't happen with mozregression.
Bug: Moving top sites - moves to the the position +x (where x = sponsored positions) and generates new topsites placeeholders
Status: RESOLVED
Priority: P2
Resolution: DUPLICATE
Created: 2020-10-28 07:20:47+00:00
Resolved: 2020-12-02 16:39:35+00:00

##### [Sugested Severity:]
S2

##### [Description:]
There are cases when moving topsites around, causes the move to be made to a position incremented by the number of shown sponsored topsites(?). Also, doing it a while, it would cause bug 1673429 and additionally to create new topsites placeholders(>32+)  


##### [Environment:]
Windows 10
83.0b5

##### [Preconditions:]
Position 1 and Position 2 have sponsored top sites.
Position 32 has sponsored top site.

##### [Steps:]
1. Download and install RO localized Firefox.
2. Create an user.js and set: browser.topsites.useRemoteSetting = true and browser.search.region to "RO", connecting to the staging main-preview.
3. Start the browser with the predefined profile.
4. Open a new about:preferences#home and set topsites to be shown on 4 rows.
5. Open a new tab.
6. Observe the topsites section.
7. Drag and drop position 32 sponsored top site to position random position. 
8. Move a normal topsite to another position.
9. Redo 7. or 8. multiple times. 

##### [Actual Result:]
6.  Top sites are listed correctly: positions 1,2,32 have sponsored topsites
7/8. Given the preconditions, you will get the top site moved to position +2
9. Weird things start happening: bug 1673429, new topsites placeholders (check [video_recording](https://drive.google.com/file/d/1S2DzXc-wqzhV19mHQPHqssgdYdETeb5o/view?usp=sharing))

##### [Expected Result:]
Topsites get moved to the chosen position.

##### [Note:]
Please note that there is a trigger for the reported behavior, it's intermittent and not always reproducible.

Close the browser completely (all tab)
Open the browser, in the preference menu, the settings: "Open link in a new tab instead of new window" is still activated (the checkbox is checked) and when i click on links they open in a new tab (instead of a new window)

Random Telemetry results for DuckDuckGo search with ads


**Tested on**
Windows10 64bit

**with versions**
Firefox 82.0.1
Firefox 84.0a1
Firefox 83.0b5

**Description**
As part of the VPN tests that we are doing i found that "browser.search.with_ads"
gets populated in telemetry randomly (this issue happened WITH and Without VPN)
It took a lot of tries to find, sometimes i was getting it on telemetry and sometimes it was not showing up


**Steps to reproduce**
- Launch new profile (firefox Nightly 84.0.a1) and i just used a user.js with user_pref("browser.search.log", true); 
- set duckduckgo as default engine.
- in Urlbar search for "lenovo laptop"
- then open about:Telemetry and search for browser.search.with_ads
- Repeat the process many times, with a new profile , with the same profile restarting firefox, with a second brand new profile)

**expected result**
"browser.search.with_ads" should appear (most of the times it does)

**actual result**
 it was detected correctly most of the times. but in about 2 out of 10 tries the "browser.search.with_ads" was just missing.
Something that looks like random.

attached are two sets with screenshots and browser console data, also links that appears on duckduckgo search, and telemetry screenshots.



**Notes** 
This randomly happened also when doing a context menu search. 
Going into www.emag.ro then highlight "Samsung Galaxy A20e" and with a right click search with duckduckgo.

Most of the time it worked, but sometimes it did not work (screenshots for this are in 2.zip)

i will update the bug once i finish testing on Mac and Ubuntu with release/beta/nightly
Bug: CSS transition property has no effect on the SVG transform attribute

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:81.0) Gecko/20100101 Firefox/81.0

Steps to reproduce:

Make a website with SVG content. Give one of the SVG elements `transform` attribute like this:

```svg
<rect 
        width="10" 
        height="10" 
        transform="translate(0, 0)"
>
```

Apply a stylesheet with a `transition` property, e.g.:

```css
rect {
  transition: transform, 500ms;
}
```

Use a script to change the `transform` on the SVG element.

See the reduced example here: https://codepen.io/tad-lispy/pen/jOrYgOm


Actual results:

The transformation changes abruptly.


Expected results:

The transformation would transition over specified duration.

I saw this in the wild when canceling the restart prompt after enabling Fission a few days ago but haven't been able to reproduce it anymore. I am wondering if there was another pref that was getting toggled and the two were in competition with each other.

I have written a test to reproduce it and the test is passing. We could land this new test and update it as needed if we find better steps to reproduce.

Click "play with computer" (or in some manner start a chess game). 

Click to move a piece. Verify that no sounds plays through output device.

Bug: Use better colors for the search mode indicator in Windows high-contrast mode

Resolved: 2020-11-13 14:04:20+00:00

Currently the search indicator uses the default/light colors in Windows high-contrast mode. They look out of place, and as [Tim suggests](https://phabricator.services.mozilla.com/D95066#3068156), we should use system colors anyway:

> High-contrast mode can also be completely light with black borders on Windows, not sure that would fit well in this case. Best choice for HC-mode would be using system colors (Highlight + HighlightText maybe?).

Actual results:

Expected results:

what should have happened: the image coming with the tweet should have loaded up in my firefox.

Precision: I had already "fixed" that problem in the past, with a solution explained in https://www.reddit.com/r/firefox/comments/j9fs5w/image_tweet_embedded_into_other_websites_texts/ , consiting of adding this to about:config
urlclassifier.features.socialtracking.skipURLs = *.twitter.com, *.twimg.com
urlclassifier.trackingSkipURLs = *.twitter.com, *.twimg.com

However, for some reason, this about:config tweak doesn't work anymore, image tweets fail to load once again since yesterday, in every page of every website I've tested.

More testing: opening the image URL directly (from tweet https://twitter.com/i/web/status/1321134572105572352 to image https://pbs.twimg.com/media/ElV7lPaXUAAXJP-?format=jpg&name=900x900 ) and clicking to disable tracking protection in Firefox for pbs.twimg.com didn't change anything.

Just what has always happened: Bookmarks → Show All Bookmarks (which has now been relegated to Ctrl+Shift+O).

I extremely strongly dislike this change. I can’t imagine many people ever want to toggle bookmarks toolbar visibility, so I simply don’t think it should *have* a keyboard shortcut; and when you want want to look at all your bookmarks, Ctrl+B and Ctrl+Shift+B are the two obvious shortcuts, and what have always been used; Ctrl+Shift+O is not discoverable.

(Personal background: I hate the bookmarks toolbar and have always had it disabled. I’ve just had to disable it again with these recent changes that make it default to showing on new tabs, but problems with that are another matter that I’ll file separately.)

This is a change from the last few days.
