Firefox for Android

Steps to reproduce:

From a firefox browser on 3 different computers and my android phone, I am unable to log into firefox when signing up a new account on any device.


Actual results:

attempted to log into sync, enter my correct/active gmail ID, I get the code, but the computer and phone browser flips to an error within 3 seconds, and it will take me 5-8 seconds to enter the code.


Expected results:

I should be allowed to login, completing my ID setup and then repeat this login across all devices.
Bug: After update to v91.0, websites look ugly, v90.0.2 is okay

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.131 Safari/537.36

Steps to reproduce:

In version 90.0.2, all websites looked nice. FF updated itself to v91, and all websites are really ugly and unuseable. 

Went back to 90.0.2 - all was well again. Updated again: same result. Deleted all caches and  cookies,  started Firefox in "safe mode", have reset Firefox (started it with the Option key pressed), tried to open pages in a "private" window, changed security settings between standard and strong, etc - all with no effect.  

This happened on 2 different Macs: 

1) iMac (Retina 5K, 27-inch, Late 2015), Intel Core i5, 8 GB RAM, macOS 10.14.6 (Mojave).

2) MacBook Air (Retina, 13 inch, 2020), 1.1 GHz QuadCore Intel Core i5, 16 GB RAM, macOS 10.15.7 (Catalina).


Actual results:

You can see - with one example site - how a website used to look like and how it does look now with FF 91.0

On top, the site as it should appear 
On bottom, the "new look" of Firefox 91.0 - really awful and unuseable


Expected results:

I want to see the website as it was displayed before, and as it is displayed by other browsers like Google Chrome, Safari and Opera.

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

Due to my unresolved bug 1706400, I set the config option browser.proton.tabs.enabled, to false so my tabs are once again tabs rather than disconnected floating buttons. 


Actual results:

But it seems as of the update to Nightly 91, this preference is no longer respected.

The same is true for:
* browser.proton.enabled
* browser.proton.toolbar.version
* browser.proton.contextmenus.enabled

I'm currently on Nightly 93 (MacOS Big Sur) and the problem persists.


Expected results:

My preference was honored, at least until the Proton UI bugs are resolved.

After the latest update of the Firefox Developer Edition, v. 92.0b2 (64-bit), rearranging the bookmarks inside their folders, does not show the new position of the bookmark, and Firefox needs to be restarted in order to show the changes.

Additionally, when the mouse pointer hovers over a list of bookmarks, the bookmark over which the pointer is, does not get highlighted which often leads to the wrong bookmark being selected.
Bug: Widevine plugin DLL can't be loaded with S Mode restrictions
Status: NEW
Priority: P3
Created: 2021-08-12 20:26:50+00:00
Resolved: 2025-01-28 19:37:29+00:00

Following the procedure for "Production mode policy with self-signed apps" in [Test your Windows app for Windows 10 in S mode](https://docs.microsoft.com/en-us/windows/msix/desktop/desktop-to-uwp-test-windows-s) (the pfx, cer, and p7b files below come from the link [here](https://docs.microsoft.com/en-us/windows/msix/desktop/desktop-to-uwp-test-windows-s#first-download-the-policies-and-then-choose-one)).

Steps to reproduce:

1. Produce an MSIX signed with AppxTestRootAgency.pfx

* Fetch a Nightly zip like [this one](https://archive.mozilla.org/pub/firefox/nightly/2021/08/2021-08-12-09-26-07-mozilla-central/firefox-93.0a1.en-US.win64.zip)

* Repackage as MSIX, specifying a the test publisher:

```
./mach repackage msix --input firefox-93.0a1.en-US.win64.zip --channel nightly --arch x86_64 --publisher "CN=Appx Test Root Agency Ex" --output firefox.msix
```

* Sign (easiest to do this directly with signtool):

```
signtool /fd SHA256 /f AppxTestRootAgency.pfx firefox.msix
```

2. Set up a Windows 10 Pro VM to simulate S Mode restrictions

* Install `AppxTestRootAgency.cer` to the local machine root store

* Copy `SiPolicy_DevModeEx_Enforced.p7b` to `C:\Windows\System32\CodeIntegrity\SIPolicy.P7B`

* Reboot

3. Install firefox.msix on the VM (should work with just a double click to launch App Installer)

4. Visit https://bitmovin.com/demos/drm

Above the video will be a message "Detected [Firefox logo], using Widevine". Attempting to play the video will churn for a while and fail, with these errors in the Code Integrity event log:

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

Steps to reproduce:

1 - Open Firefox in a Linux environment (in my case, Xubuntu 20.04).
2 - Access any page.
3 - Activate full screen mode.


Actual results:

The window control buttons (minimize, maximize and close) follow the standard Windows 10 style and not the style of my environment. The buttons do not respect the defined window manager theme (xfwm) nor the default GTK theme (Adwaita).


Expected results:

The buttons style must follow the visual pattern of my system and not Windows.

Bug: Cannot disable protonui, nor downgrading back to v90
Status: RESOLVED
Priority: --
Resolution: INVALID
Created: 2021-08-13 05:02:36+00:00
Resolved: 2021-08-13 06:40:31+00:00

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.131 Safari/537.36

Steps to reproduce:

Firefox asked me to upgrade to v91 from v90. I did so. 

After that, that terrible ProtonUI appeared again which I already disabled in v90. I wanted to disable it again how I did earlier. So, I typed about:config and adjusted the appropriate flags to false. It did not work.
 
I read in forums that those flags don't work anymore. So, I reinstalled the previous version (v90). But when I start it, it is complaining about my profile being too new and not compatible with v91. It asks me to create a new one. 

I don't want to create the new profile because I have >200 megabytes of data in the old one which I don't want to lose. 

I tried tricks like `/Applications/Firefox.app/Contents/MacOS/firefox-bin -p --allow downgrade` but nothing worked. 


Actual results:

After using Firefox as my primary browser for more than 20 years, I started to look for another browser. (Vivaldi is my candidate now.) 

Yes, I will need to rebuild a profile in Vivaldi too but I hope they will not stub in my back, like Firefox did.


Expected results:

Any of the following solution could have worked:

1. Firefox v90 alerts me ahead about the non-reversible change. For example, like this:
> Hey, the new version comes with a new UI which you may or may not like. 
> You won't be able to return to the older version of Firefox so back up your profile if you plan to do that.

2. Add an option to Firefox to disable the new UI. 
Why the hell do you think that a significant UI change _you_ like will be good for _everyone_? Why don't you believe that UI is the most critical component of a software which you must not change without giving us a chance to turn it back?

3. Give me a chance to use the old version of my profile. 
I don't mind if it is a dedicated profile-converter tool or Firefox can convert profile back and forth by itself. But locking me out of my profile this way is something I cannot accept.

Resolved: 2021-08-13 22:08:43+00:00

I have this odd intermittent problem. Sometimes I will navigate to a page, then navigate away and browse elsewhere. Then, some time later, I will want to navigate back to that page. I'll type part of the title into the address bar in order to find it in the history and navigate back to it. But when I find the correct entry, it will have the "Switch to tab" badge next to it even though the page is not currently open in any tab. If I navigate to that entry and hit <enter>, the page does not navigate anywhere nor do I switch to another tab.

If I close the tab that had navigated to that page and open a new tab, I can find the entry in the address bar again and it will no longer have the "Switch to tab" badge, allowing me to navigate to it properly.

All three navigation buttons (back, forward, refresh) are greyed out. Settings menu, new tab do not open as intended. Still am able to close current tab/browser.

Replicated in Troubleshooting mode as well.
