Hi folks

I have a particularly infuriating problem. A few weeks back, Firefox stopped displaying my usernames and passwords whenever I wanted to log into a site. This coincided with my installing BitDefender, although I don't know why.

Through googling I eventually realised I could go into about:config to fix this. signon.rememberSignons displays as false, when I turn it to true it fixes the issue.

But here is the problem I can't solve. Everytime I restart firefox or my PC / Mac (I am using both, with a syncronised account on both windows and MacOS) it sets signon.rememberSignons to false AGAIN. Which means every single time I browse I have to go into about:config and fix this. Maddening.

Please can you help?

The font size in "Manage Bookmarks" is way too large, both in the sections list menu on the left and the list of bookmarks. I checked my userChrome.css file as well as the layout.css.devPixelsPerPx entry in about:config and there's nothing there to explain why only the "Manage Bookmarks" text is so large.

It's possible I changed a setting somewhere that's causing this. But I'm stumped re: what setting might be controlling the font size in only that UI. All other Firefox text sizes are good.

Thanks to anyone who knows where I should be looking

Thanks to the help received here and in the Reddit group I've been able to transfer almost all of my old colour and layout tweaks to a new intallation of Firefox (v133) on a new PC (running Windows 10). There's one thing that I haven't succeeded with though: I'd like to change the colour of the text in a tab when that tab becomes the active one.

This is the coding I'm using to change the tab's background colour when it's selected:

  1. TabsToolbar .tab-background[selected]{

background: white !important; }

This works perfectly. But when I tried adding the line

color: black !important;

It had no effect. I'd be grateful for any thoughts. Many thanks.

Good afternoon,

We're currently trying to set up a Hardening Guide for Firefox ESR but are struggling with a few policies and setting wildcards.

For example, we're trying to set an origin in Cookies > Block Settings to something like "*", and we get the error "Ignoring parameter "*" - not a valid origin."

In Chrome / Edge you can set a wildcard like this: [*.]google.com for example - we receive the same error message for this.

Can you do such a thing for Firefox ESR without having to list every site you want to block?

ESR Version: 115.6.0esr (64-bit)

Kind Regards, Ethan Jerrum

We need that to specific container, but still I dont know how to set it up, even via regedit, or preferences. Can someone describe me when can I set it up ? It could be using json file (which exactly file and how?), registry or just gpo. Regards, M.

Hello, I am trying to create a deny all & white list only gpo for Firefox extensions.

I am using the gpo; Computer Configuration/Policies/Administrative Templates/Mozilla/Firefox/Extensions/Extension Management

I started out simple using a template which worked.

{ "*": { "blocked_install_message": "Your Company Blocked Message", "installation_mode": "blocked" }, "uBlock0@raymondhill.net": { "installation_mode": "allowed" } }

However, when I tried to add in more allowed extensions it now longer worked and was able to install any extension.

{ "*": { "blocked_install_message": "Your Company Blocked Message", "installation_mode": "blocked" }, "uBlock0@raymondhill.net": { "installation_mode": "allowed" }, "querymoid@kaply.com": { "installation_mode": "allowed" } }

Hi!

Using Intune, we are setting some settings in Firefox. One that is a bit troublesome is the ExtensionSettings

Currently looks like this:

{

 "*": {
   "blocked_install_message": "Blocked.",
   "installation_mode": "blocked"
 },
 "uBlock0@raymondhill.net": {
   "installation_mode": "allowed"
 },
 "addon@darkreader.org": {
   "installation_mode": "allowed"
 },
 "@react-devtools": {
   "installation_mode": "allowed"
 }

}

I get the Blocked message if I try any of the allowed extentions like uBlock, Dark Reader or React Dev Tools.

I can add that uBlock had "force_installed" (With URL since that is required for force) and that worked fine.

Hello I have installed german Firefox Version 117.0 (Build-ID 20230824132758) on Windows 10.

The following ExtensionSettings policy works as expected. The addons ublock and TreeTabs are both installed automatically.


{

 "*": {
   "blocked_install_message": "My Message",
   "install_sources": ["https://addons.mozilla.org/"],
   "installation_mode": "blocked",
   "allowed_types": ["locale", "extension"]
 },
 "uBlock0@raymondhill.net": {
   "installation_mode": "force_installed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/ublock-origin/latest.xpi",
   "default_area": "navbar"
 },
 "TreeTabs@jagiello.it": {
   "installation_mode": "force_installed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/tree-tabs/latest.xpi"
 }

}


But I don't want TreeTabs to be installed automatically on all workstations. So I want to change installation_mode to allowed.


{

 "*": {
   "blocked_install_message": "My Message",
   "install_sources": ["https://addons.mozilla.org/"],
   "installation_mode": "blocked",
   "allowed_types": ["locale", "extension"]
 },
 "uBlock0@raymondhill.net": {
   "installation_mode": "force_installed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/ublock-origin/latest.xpi",
   "default_area": "navbar"
 },
 "TreeTabs@jagiello.it": {
   "installation_mode": "allowed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/tree-tabs/latest.xpi"
 }

}


But with this setting I'm unable to install it manually from https://addons.mozilla.org/de/firefox/addon/tree-tabs/ The message "An unexpected error occurred during installation." and a popup with the "blocked_install_message" "My Message" is displayed.

The same error occurs without the line (and the comma) "install_url": "https://addons.mozilla.org/firefox/downloads/latest/tree-tabs/latest.xpi"

I don't know why this does not work. Please help. Thank you.

One of our vendors websites does not load under Firefox ESR, with errors in the console pointing to CSP. Error is: Content Security Policy: The page's settings blocked the loading of a resource at inline ("default-src")

However if I load the site under the normal Firefox release, it displays correctly. When looking at errors in console, it is showing 3 errors for CSP, however it does not stop the site from working correctly. Content-Security-Policy: The page's settings blocked the loading of a resources at https://..... ("connect-src") or ("img-src")

The site is https://app.approvalmax.com If you get the login screen then the site is working otherwise just getting a green background when it is not working.

I am unsure why ESR and RR versions are behaving differently in this case. Using the latest versions of each.

I need to set the max TLS version to 1.3 and the min version to 1.2 on my shstems. The max and min TLS versions are set to 4 and 3 by default in about:config. If I use lockPref(“security.tls.version.max”,”3”), it is still 4 in about:config for some reason. If I set the min version to 2, it is still 3. This also doesn’t work if I use “SSLVersionMin”: “tls1.2” how can I fix this issue? Thank you in advance!

I am using the intune preview feature which allows you to import admx/adml instead of using the custom injection method. Everything works far better then with the injection method, except for one settings:

ExtensionSettings this setting is working when I have only one setting set (ex):

{"someplugin@test.com": { "installation_mode" : "allowed" }}

If I add a second line to the entry:

{"someotherplugin@test.com":{ "installation_mode" : "allowed"}}

I understand this is a new feature, but if I had the correct format that would work for HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox\ExtensionSettings to allow two plugins to work I belive I shouldn't have any issue getting the admx feature to do this, I even tried manually editing the registry setting and it breaks whenever I add the second line to it.

Is someone able to point me in the right direction?

Version: Firefox ESR 102.9.0 (64-bit) - Windows 10 Enterprise 22H2

Customers have been complaining for about 6 months that they can no longer drag and drop email attachments from Outlook (Microsoft Office Professional Plus 2019 - Exchange) into a Help Desk formula. I tested dragging from Outlook desktop and from the web version.

Drag and Drop works when using Edge and Chrome.

This is not a major issue, since customers can use the other browsers, but since they would prefer to use Firefox, a fix would really be appreciated.  :-)
