Hey everyone. I am automating end-to-end testing with playwright for python, using the official Docker image from the microsoft artifact repository (using `playwright/python:v1.49.1`).

As I have signed certificates for my local domains with my own certificate authority, I am trying to have Firefox automatically install the certificates via a policies file. However, Firefox seems to ignore the policies file no matter what.

To ensure that the file itself is used, I simplified it to a single boolean value, and ensured that it's copied correctly inside the container via the `cat` command. Here are the current contents:

{

 "policies": {
   "DisableTelemetry": true

}

I know that the CA certificate is installed correctly, as it works out of the box using the WebKit browser and Curl command. I have gotten it to work in Chromium by installing it to nssdb using `certutil`.

I have converted the file from ASCII to the `utf-8` charset.

The file has the expected content, and I have copied it to both `/etc/firefox/policies/policies.json` and `/ms-playwright/firefox-1466/firefox/distribution/policies.json` (the path to the binary is `/ms-playwright/firefox-1466/firefox/firefox`).

Opening `about:policies` shows the text "The Enterprise Policies service is inactive.", which is sadly not very informative. It would be nice to have a list of locations it looks in, and any problems it encountered.

The container uses Firefox Nightly 132.

Are these locations incorrect? Is there any way to debug this? Does anyone have any other suggestions? If you need any more info (Dockerfile, etc.), please let me know.

Thanks in advance.

How do I permanently change the "overflows" attribute of the new sidebar button to false so it doesn't disappear on me when I resize the window and I still need my tabs?

In the year 2024, firefox still does not allow a simple way to set any URL you would like as the new tab url (without an extension).

Users were previously able to use extensions like NewTab override to have a relatively seamless experience changing their new tab page. However after certain changes, these said extensions can no longer set your new tab page to a local file, and can also no longer clear and focus the address bar.

I am simply requesting a feature within firefox to set a custom new tab page, without having to create any external configs, or without using any extensions. This basic feature has been available in chromium browsers for years, and firefox already includes a feature just like this for the "Homepage and new windows" setting, where it allows you to input a custom URL to a local file or site to put it as your homepage. However, this same setting for some odd reason does not exist for the "new tabs" option. Why is this?

As of now, I've had to use a manual override along the lines of this:

``` // shenanigans for setting a different new tab page const { classes: Cc, interfaces: Ci, utils: Cu } = Components; const { AboutNewTab } = Cu.import("resource:///modules/AboutNewTab.jsm", {}); // path to new tab can be a url or file const newTabURL = "file:///home/faaris/.local/packages/startpage/fazzi/index.html"; // set the new tab URL AboutNewTab.newTabURL = newTabURL; ```

this should not be needed. Having to modify files in system protected folders should not be needed for such a simple option.

When I created the theme for Firefox and Saved it I exported it after that it asked me to pick a file type when I did that I used the XPI file and it keeps calling it corrupted I don't know why but I won't answers please

Mozilla please make a browser that has the proton/photon like firefox 89 please i need it Btw you also ruined the firefox layout floating tab what we really need is a secure browser with no bloat and open-sorsorce

I just purchased a year subscription for the Mozilla VPN. I want to be able to verify that the FireFox browser I'm using is accessing the web via the VPN. How do I verify that? I don't see any icon indicated that it's a VPN connection.

I walked away from my laptop for about an hour and when I came back my task bar was gone. What happened to it? and how do I get it back? Below is the spec's of my lap top that I use/have been using/task bar missing

Secure Connection Failed

An error occurred during a connection to myiphide.com. PR_CONNECT_RESET_ERROR

Could you please let me know how I can change the Wallpaper to show an image I'd like to use and use in other browsers? Firefox is my preferred browser but I'd like to customize it to my preferences. Thank you

Im trying to change color of font for unread email for the latest version. To do this its says you have to edit the chrome/userChrome.css file in Style Editor.

With earlier versions from what Ive read they had settings inbuilt to chnage font color within "Display" tab, for some reason it has been removed in later versions

Im following these instructions https://devnodes.in/blog/misc/thunderbird-mail-theme-customize/

There's a part where it says "Next create file chrome/userChrome.css" in Thunderbird’s Profiles directory , but it doesnt say how to create it.

I tried creating a folder called chrome in the profiles directory, then creating a file named userCrome.css using notepad but the style editor doesnt list this/see file.

Can I change colors of individual tabs? without an extension?

Maybe add an option to right click and select a color wheel or color selector to assign a color to that particular tab. Especially if its bookmarked or pinned.
