Firefox Community Forum

I made a custom theme for firefox and submitted it to AMO. It's approved, but I have no idea how to actually apply it. I don't see any option to install or use. What am I missing? How do I actually use it?

Windows 11 Pro - Dell XPS8940 desktop - i9

Firefox will not play video from a website. If I save the video, it is a MP4 file. Windows Media Player and VLC will play the video file. But the browser shows the message: "No video with supported format and MIME type found."

Chrome and Edge will play this video correctly in their browsers. Firefox will not play the video on 3 different computers, and even when a different user account is involved (without Firefox sync).

The evidence seems to point at firefox. The website is a Wordpress site.

Is it possible that the website is the problem? If so, why do Edge and Chrome work?

I uninstalled Firefox (latest version) and reinstalled it. Not fixed.

My windows updates are current, as are Dell updates.

This is stumping me. I hope someone can help.

Anyone know if the Firefox app will be in the Microsoft Store soon for download?

I bought a new computer and if I download the app from the website I will permanently be taken out of S mode (I’m sure you guys are aware of this issue).

Im hoping the app will be available through the Microsoft Store very soon because I only use the Firefox browser on all of my other devices.

Is there a way around it other than permanently switching out of S mode and downloading? I’m aware I can do that but prefer not to.

Thank you!

Changed behavior of autofill is a small thing. A few weeks ago, I could enter the first few letters of a site and then down arrow to choose one from the list. Down arrow no longer works here.

A significantly bigger issue allowing a website to open a window or tab or popup. There used to be two buttons when this happens, allow and always allow. Always allow is no longer a choice. I have to click allow every single time I go to that web site. Since two of those sites are the enrollment and learning management systems where I work, I'm doing that 20 times a day. If disappearing the always allow button was a design decision, it was a bad one.

I used the CSS animation property called animation-timeline , which is written as:

element{ animation-time: view(); }

When I view the webpage on Chrome, Edge, Opera, and even on Phoenix browser, the animation works.

It is only on Firefox that the animation does not work. I even added the Vendor-prefix of " -moz-animation-timeline " to the CSS property, and it still didn't work on Firefox, while it is working on all other browsers.

The CAN I USE website ( https://caniuse.com/?search=animation-timeline ) tells me that Firefox does not support it at all.

It however said that I can enable it, by setting "layout.css.scroll-driven-animations.enabled" to true.

1.) I don't know what that means.

2.) Would my website's users be able to see the animation on their Firefox browser, if we assume that I make this setting ?

3.) I am using Firefox version 138.0.3 (64-bit) : What can I do to see that both I and users of my website are able to see this animation on Firefox ?

Regards.

while ysing the New York Times i tried to open the Athletic Section of the App and this was the result....Application error: a client-side exception has occurred (see the browser console for more information)....I cannot find information, can you help

This will be a long question and in 2 parts, so I'll apologize up front.

1. I am running FireFox on my 11-year old MacBook and love it (MacOS Mojave version 10.14.6). However, my printer just crapped out, and my new HP 9120e requires MacOS Big Sur (11.x.x) or later. If I update to that OS, will I still be able to use FireFox? If so, where do I find it (see Question 2, below)?

2. Since my old MacBook is clearly reaching the end of it's life and my Excel and Word apps are also ancient, I am trying to transfer all my stuff onto a "New" MacBook that is running MacOS Monterey version 12.0.1. However, the "New" computer (I will not say "improved") has been a reliability nightmare and I just had it in for service. They wiped my disk clean to install the Monterey OS. So, other than Safari, I have no browser (or anything else for that matter). When I go to the App Store to download FireFox, and don't see it anywhere. Help!

I've been looking at firewall logs for my client and router software firewalls. My 3rd party firewall flags repeated outgoing TCP packets to IP 34.149.100.209 as coming from Firefox and 'Restricted', although restricted is the firewall apps syntax. When I look at the router firewall on WAN it was seeing the same IP outgoing. These packets only originate when Firefox (latest version) opens. Perhaps there's nothing to worry about or it's there to poll for those who want to select a Google search engine? Anyway, I've added a rule in the router to block the IP, although I think Google use other IPs.

There is plenty of web discussion to REMOVE restricted from Firefox but I want to make sure 'Restricted' in my case means BLOCKED, is that possible or do I misunderstand what restricted means? Thanks
