Created: 2021-03-29 11:57:00+00:00
Resolved: 2021-04-29 07:26:08+00:00

**Tested on:**
Nightly 89.0a1

**TestedPlatform:**
Windows 7/10
MacOS 10.15

Bug: [macOS] Bookmarks toolbar button submenu item hover states are low-contrast
Status: VERIFIED
Priority: P2
Resolution: FIXED
Created: 2021-03-29 12:39:16+00:00
Resolved: 2021-05-17 14:08:10+00:00

The submenus in the bookmarks toolbar button are styled like native menus, at least on macOS. We appear to apply the Secondary Hover bgcolor to them on hover. This is very low-contrast. We might consider using a blue/system Highlight hover bgcolor for the items in these submenus.

**Affected versions**
- 89.0a1 (2021-03-28) 

**Affected platforms**
- Windows 10
- macOS  11
- Ubuntu 20.04

**Steps to reproduce**
1. Make sure browser.proton.enabled is set on true in about:config
2. Open about:debugging 
4. Navigate using the  TAB key in order to reach the buttons on the page
5. Observe the highlight focus

**Expected result**
- The highlight focus styling applied is the one used for buttons

**Actual result**
- The highlight focus styling applied is the one used for links

**Regression range**
- Not a regression, Proton specific

**Additional notes**
- Set as S3, since a better consistency around all about pages is desirable
Bug: Fix more tests that fail with proton enabled

See bug 1701202.

Trypush after that still had a bunch of failing tests: https://treeherder.mozilla.org/jobs?repo=try&revision=0cb2a0177495d59e4bcdf1bf49e02fc444233701 .

We've also graduated tabs now and it would not surprise me if that yielded more failing tests.

This should also probably be P1 given it blocks enabling proton by default.
Bug: Multiple UI refreshes degrade performance of CSV Import
Status: VERIFIED
Priority: P2
Resolution: FIXED
Created: 2021-03-29 14:02:22+00:00
Resolved: 2022-02-09 15:04:19+00:00

**[Notes]**:
- Importing a CSV file with 1000 logins takes between 3 to 10 minutes. During the import, there are multiple performance issues that can be observed. The performance issues get worse after ~800/1000 logins are imported. Here are a few examples of performance issues observed:
	- Firefox can’t navigate to any page using the address bar until all logins have been imported.
	- The top sites from the new tab, cannot be opened while the CSV file is imported. If one of the top sites is clicked, then a new tab is opened, the page remains blank until the logins are imported.
	- In certain cases, Firefox also freezes. This happens after a few minutes while the importing process is about to end (when ~850 logins are imported).
	- If the about:logins page is closed while importing a CSV file then if it's reopened, the page remains blank until all the logins are imported..
	- The hover effect has a delay.
	- Opening new tabs or Firefox menus have a delay.

- Considering the fact that this is a performance issue we have captured a performance profile using the Firefox Profiler addon on multiple machines:
	- Windows 10 x64, Intel Core i7 - 10750H, 16 GB RAM: https://share.firefox.dev/3u4cXve
	- macBook Pro (Early 2015), macOS 10.15.7, Intel Core i5, 8 GB RAM: https://share.firefox.dev/3sBkKA8 
	- Linux Mint 20, AMD FX (™) - 8320, 16 GB RAM: https://share.firefox.dev/3lZd60d 
	- Windows 10 x64, Intel Core i5-6500, 16 GB RAM: https://share.firefox.dev/3m2iNKK
	
**[Affected versions]:**
- Firefox Nightly 89.0a1 (Build ID:20210328213901);
- Firefox Beta 88.0b (Build ID: 20210328185936)

**[Affected Platforms]:**
- Windows 10 x64;
- macOS 10.15.7;
- Linux Mint 20 x64;

**[Prerequisites]:**
- Have the latest Firefox Beta build installed.
- Have a large CSV file that contains multiple logins or you can use this one (1004 logins): [file](https://drive.google.com/file/d/1HMMTMlOfgNT3LFOfFn6zTEd6_sE41LQy/view?usp=sharing).

**[Steps to reproduce]:**
1. Open the Firefox browser with the profile from prerequisites.
2. Navigate to the "about:logins" page.
3. Open the menu, click the "Import from a file..." option.
4. Select and import the CSV file described in perquisites.
5. Wait until ~800 logins are imported.
6. Open a new tab, click on the top sites, navigate to multiple websites.
7. Open different Firefox menus and click on options.
8. Observe how the browser behaves.

**[Expected result]:**
 There are no noticeable performance issues.

**[Actual result]:**
- Different performance issues can be observed.

**[Additional Notes]:**
- Attached a screen recording of the issue.
Bug: [Proton] [High Contrast] The "Remember this decision

+++ This bug was initially created as a clone of Bug #1701625 +++

**Tested on:**
Nightly 89.0a1

**TestedPlatform:**
Windows 7
MacOS 10.15 

Have the following prefs enabled:
browser.proton.enabled
browser.proton.doorhangers.enabled

**Steps to reproduce:**
1. Open https://mozilla.github.io/webrtc-landing/gum_test.html
2. Click on the Camera or Microphone button (make sure you have only 1 device connected for each)
3. Check the alignment of the device name and the “Remember this decision” string

**Expected Results:**
The name of the device and the “Remember this decision” string should be aligned one under the other as in the Figma doc: https://www.figma.com/file/FjUe6ORvXZgJvI3rPuTV33/Desktop-UI-(Mozilla-Confidential-)?node-id=4561%3A40060

**Actual Results:**
The “Remember this decision” string is a few pixels more to the right compared to the device name string

**Notes:**
Disabling proton via (browser.proton.enabled) will still have a slight miss-alignment, but not so visible: See attached Image “Proton off” - browser.proton.doorhanger.enabled is still “true”.
This is reproducible for all WebRTC Permission Panels when only strings are displayed. (1 device of each type)

Bug: Proton shows keyboard highlight/border when returning from a sub-menu accessed via mouse

Created: 2021-03-29 17:29:26+00:00

**[Affected platforms:]**
Ubuntu 20
Windows 10

**[Affected versions:]**
Nightly 89.0a1

**[Description:]**
When you access a submenu with the mouse and then come back from that submenu with an arrow key, the submenu option that you left is shown with the colored solid border on the main menu, as if you had gone down to that option with the arrow keys. But since that is not the case you can't use the keyboard. So, the problem is that it shows the border, but you can't use the keyboard.

**[Steps:]**
1. Open Firefox with a new profile.
2. Open the hamburger menu (or a toolbar menu)
3. With the mouse, click on a submenu like help
4. Once on the help submenu, press the LEFT arrow to RETURN to the hamburger menu again.

**[Actual result:]**
You can't use the right arrow to access the help menu again even though you have the orange border as if you had gotten there using the keyboard.
 
**[Expected result:]**
The orange border should not be over the help option nor shown since I accessed through the mouse.

With Proton the :hover of a downloaded item in the downloads panel "looks wrong" even if it's not really wrong in a technical sense. It should probably more styled as the :hover of menu items (some spacing around the item, slightly rounded corners).

It works normally out of private mode.

Steps to reproduce:

I tried to bookmark a website by clicking on the blue star.

It did not save my bookmark and the star did not move like it usually has in the past.

Steps to reproduce:

 1. Open a fresh Firefox window.
 2. Set the bookmarks bar visibility to "Always show" and make sure you have at least one bookmark visible in the bookmarks bar.
 3. Go to about:config and click the button to accept the risk, if shown.
 4. Right-click in the content area of about:config.
 5. Right-click on a bookmark in the bookmarks bar.

Expected results:
A context menu for the bookmark should open.

Actual results:
No context menu opens. Right-clicking repeatedly does not work either.

I think this was kinda-broken for a long time and then got really broken more recently.
