In Firefox, When H264 frames are decoded and rendered within a single tab, the output reaches up to 180 fps, performing well and meeting expectations. When decoding and rendering occur on two separate tabs on parallel, performance significantly drops, impacting both processes. However, it performs smoothly when running on a single tab.

In comparison to the Brave browser, H264 decoding and rendering are noticeably slower in Firefox. Firefox manages only around 180 fps, while Brave and other Chromium-based browsers can achieve approximately 1000 fps on a single tab and around 800 fps when multiple tabs are open.

On my 2019 16-inch MacBook Pro equipped with dual GPUs, enabling danmaku (on-screen comments) while playing videos on bilibili.com causes a sudden spike in GPU usage, leading to significant heating. The issue disappears when danmaku is disabled.

Additional notes: 1. This problem does not occur in Safari or Chrome. 2. "Use recommended performance settings" is already enabled in Firefox. 3. Reinstalling Firefox did not resolve the issue.

What can I do to fix this?

Tell me how to reset a new password, I simply forgot my old one. I have been using Mozilla Foxfire for many, many years and now it's a problem because a password prompt keeps on reusing my password that is incorrect.

Hello, the other day I asked the question why logging in to Hulu and The Hartford Ins. Co. did not work on Firefox, but did work on Microsoft Edge. I received some suggestions on what to try, but the problem resolved itself after a couple of days. Lo and behold, yesterday Microsoft ran an update to Windows 11, which they seem to do every two or three days!!!) and now I have the same problem with Hulu that I had before. I get the impression Microsoft is doing that on purpose to force users to use their browser and I resent the hell out of it. Any suggestions on how to get around this problem, short of running the updates? I'd hate to quit using Firefox when streaming on Hulu.

I despise ai in every use and way with a passion. Now, it gets spammed everywhere on this browser, with no apparent way to disable and/or remove that filth. I don't want to see it, ever! Why is it even on by default??? I don't want "chatbots", "Ai assistants" or any of that shit at all.

I thought it was strange that I had to redownload Firefox to update, but the more strange thing is that it says the Mozilla website is no secure and don't let me update it, at first it gave me the certificate like I pasted below, but after that I tried to screenshot the page and the certificate sent me to another page showing things related to Amazon so maybe is something about the AWS servers going down, but I asked a friend that also uses firefox and it was fine for him, he is on the 144.0.2 as I am on the 144.0

Firefox is no longer playing audio from the Internet. I am running Firefox on Windows 11, and have the latest update installed (10/29/25). What happened? How do I fix this.

I am 99.5% sure this is a Firefox issue, as I have no problem playing audio files stored in my computer, and no problem playing Internet audio using Chrome or Edge.

Help!

I've had Firefox as my main browser on my Macbooks for over 20 years. It is becoming increasingly frustrating working on something and realizing the computer is slowing down when loading websites, only to realize there is yet another update that requires the restarting of the browser. This is especially annoying when on a Zoom meeting for instance, and trying to open a website.

I usually have 80+ tabs open across 4-5 windows. When restarting the browser, I now have to open each tab to log into whatever site I was in.

Why does Firefox have to do SOOOOOOO many frequent updates that require restarting the browser, and why does it have to slow down your computer when there is an update?

It's like you have no choice but to update it. Would it be possible to NOT slow down your computer, but give some kind of notification, say by email, when there is an important update?

SUPER FRUSTRATING!!!!!!!!!!!!!!!

Every day when I try to open a tab I get the message, "Gau. Your tab just crashed." I have to restart my computer to solve the problem. All the other browsers work. Anyone know how to solve this? Thanks in advance.

i can not access any of my yahoo accounts, i continue to get a pop up screen that says the "to many request" why should i continue to use firefox / mozilla. it keeps crashing and having issues. freezing and taking forever to load. restart everyday

Whenever I use Firefox to open sites like Google and Yahoo they appear with foreign languages like Spanish and Indonesian. Sometimes it asks me if I want translation. My default location on Firefox (weather) is in Argentina. When I open the default location to my settings, they show English (US) as the default language. I also can't change my default location to Los Angeles, California, USA.
