In Firefox, the animation exhibits performance issues like stuttering, particularly in elements that rely on animateTransform and animate for movement or opacity transitions. This issue is not present in Chrome, where the animations run smoothly without any noticeable lag.

Expected Behavior: The animation should render smoothly on both Chrome and Firefox without any stuttering or lag, providing a seamless experience for users.

Steps to Reproduce:

Open the provided SVG code in Firefox.

Observe the animation, particularly the elements with animate and animateTransform attributes.

Notice the stuttering or lag compared to the smooth rendering in Chrome.

I am using firefox on linux since ~10 years. Currently running latest FF on Kubuntu. I always had setting set to forget all cookies and session details except of search history on exit.

Since approx 2-3 weeks (latest update?) those settings don't work. FF remembers everything regardless of settings I chose.

Does anyone have idea why this is happening now and how to fix it?

I tried the firefox VPN. I Followed the instructions at:

https://support.mozilla.org/en-US/kb/built-in-vpn#w_are-any-websites-excluded-from-vpn-protection

But no 'VPN' button appears when I sign in (I am in a valid country and was told about the VPN by my browsers update). I have tried restarting and checking the toolbar, but the VPN button that is supposed to be there is not.

Hi,

Looking at my Firefox 147.0.1 settings for macOS 26.2 (Apple M1), I'm trying to adjust two settings:

-- I'd like to remove Languages -> English (GB) (its existence has odd side effects, like triggering United Airlines to offer fares in Pounds Sterling, and I'd prefer to just have English (US))

-- I'd like to disable Play Audio and Video for about:welcome (in regular and private windows)

I can see no way to accomplish this currently -- why?

Thanks.

Many verification emails have been sent. None of the links work. It’s also next to impossible to find a way to reach you so my account doesn’t get deleted. Smh……..

I had been using the Mozilla Firefox VPN for a few weeks, but now it will not launch. I sign in without a problem but when I click on the VPN icon on the toolbar, nothing happens. I just get the pop-up to try the VPN and "Get Started" (see attachment).

Please advise.

I often keep many tabs open for research, and Firefox memory usage grows significantly over time. Are there practical settings or habits that help manage memory without sacrificing usability?

When I logged in this morning my FireFox screen had changed. The window for searches had disappeared and the "pocket" selections were all about India and its events. None of the previous options were there. What happened and how do I get back to where things were?

I am a business owner and I need to log into united health care provider portal. Mozilla will not allow me to access. I'm using this link: https://secure.uhcprovider.com/ and Mozilla will not allow me to go further. This is causing work stoppage. Chat GPT says the link is secure. HELP! I need access so I can get paid.

From Chat GTP:

https://secure.uhcprovider.com/ I checked that exact URL, and here’s the key point:

👉 secure.uhcprovider.com is actually configured with HTTPS and a valid SSL certificate—so under normal conditions, your browser should show it as secure.

So if your browser is blocking it or labeling it “not secure,” the problem is almost certainly local (your device/network) rather than a new issue with UHC.

Again Firefox? Again? Third time the charm or something? Stop this ridiculous handoff from Search bar in page to URL bar for searches. It's not safe, helpful, or anything other than confusing. Give us the Option. Seriously, it is why we use FF in the first place, Despite tons of companies not supporting it well for website access. I am mad and literally after decades of use am making my first formal complaint. Fix This Please. Add a bunch of appropriate curse words here please. Thanks and keep up all the other great work.

After upgrading from Firefox version 149 to version 150, I am no longer able to log in to Facebook using Firefox, although login attempts are successful in other browsers. Could you please clarify whether this issue is unintentional, or if there is a strategic reason behind it?

Svp, comment changer la couleur de la barre latérale ?

La mienne était toujours blanche, mais vient de changer à mon insu pour du bleu ...

Merci de m'aider.
