Bug: non standard port in url prevents popup whitelist GPO application and tagging
Status: RESOLVED
Priority: --
Resolution: WORKSFORME
Created: 2020-01-31 10:47:50+00:00
Resolved: 2020-02-03 15:59:41+00:00

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:72.0) Gecko/20100101 Firefox/72.0

Steps to reproduce:

Set up a Computer GPO to whitelist our internal company domain in the popup blocker, in the following format :
https://domain.tld
http://domain.tld




Actual results:

The GPO applies properly, both exceptions are listed in the browser settings and the whitelist works fine on all standard URLs.
However, when we try to access a server with the following url format, the setting is ignored and the popup blocker is active : http(s)://server.domain.tld:portnumber

If we try to set up a specific exception for this server in the GPO by adding http(s)://server.domain.tld:portnumber to the whitelist, the entry isn't added by firefox either after proper GPO sync and browser relaunch.

Adding the exception manually in about:preferences works.


Expected results:

The popup exceptions in Firefox should tag urls properly no matter which port is specified for the given whitelisted domain.

The Computer GPO for popup whitelisting should allow for non standard ports to be specified.

Bug: _adjustFocusAfterTabSwitch can run before or after TabSelect
Status: NEW
Priority: P2
Created: 2020-01-31 16:14:26+00:00
Resolved: 2022-10-11 23:54:26+00:00

For Bug 1601052 I'm implementing a workaround where I have to wait for both TabSelect and the focus change, to be sure we touch the urlbar at the right time after a tab switch.
This happens more often when switching tabs repeatedly, the TabSelect event normally fires after _adjustFocusAfterTabSwitch, but sometimes it fires before it, so we get a TabSelect  and then the focus changes to/from the urlbar.
Having a reliable timeline would help with implementing features, and it's unclear if this may be a cause for intermittent failures.

+++ This bug was initially created as a clone of Bug #832423 +++

User Agent was taken from: http://browser-update.org/test/bar.html

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:60.5) Gecko/20100101 Firefox/60.5

Steps to reproduce:

In Firefox 72.0.2, the user agent string is similar to the following:  

User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:60.5) Gecko/20100101 Firefox/60.5

OS: MacOS (10.15.1) Beta


Actual results:
Firefox version is not. Which some features of Github will not load because of "Old browser version"


Expected results:
Firefox/60.5 should read Firefox/72.0

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:72.0) Gecko/20100101 Firefox/72.0

Steps to reproduce:

Pin a tab (such as gmail)
Have many other normal tabs open (over 15-20)
From your pinned tab click a link that opens a new tab.


Actual results:

New tab opens to the far left (first) tab


Expected results:

New Tab opened FROM pinned tab should be treated as a "Ctrl+T" like new tab. The current behavior is what you would expect from a normal tab opening a new one directly to its right, but in a pinned tab environment, the new tab should open as an actual new tab at the end of the list.

Note that the close button of the tab is preceded by the picture in picture icon.

Hover over the picture in picture icon on the tab (see screenshot)


Actual results:

Bug: Shift clicking navigation buttons in private browsing opens content in non-private browsing window
Status: VERIFIED
Priority: P2
Resolution: FIXED
Created: 2020-02-01 03:22:17+00:00
Resolved: 2020-04-14 11:31:41+00:00

As reported by a user on the support forums, there appears to be an issue when shift clicking the navigation buttons in private browsing mode.

To reproduce the issue, open a new private window and navigate to a few different websites. Then, hold down shift on the keyboard and click the back button on the toolbar. Since the history of that tab is tied into private browsing, it would be expected that the shift shortcut would open a new private browsing window.

However, it opens the page in a new non-private browsing window. This issue is a potential privacy bug, since the page would then be logged into the user's history and cache/cookies would be saved.

I've been able to reproduce the issue on Windows 10, but I assume the bug happens on all systems.

Also, suggestion like "about:conf" -> "about:config" always works.
