Hi everyone,

We’re testing scroll-linked animations on a landing page built with Tailwind and custom JS for our client project hosted at https://noveltyads.com. Specifically, we’re exploring the ViewTimeline API and CSS animation-timeline for a horizontal scroll section.

While everything works smoothly in Chromium-based browsers, we’ve noticed Firefox behaves inconsistently in the following ways:

The animation-timeline: view() property doesn’t always trigger on scroll as expected.

Debugging with Firefox DevTools, the animations don’t appear in the Animation panel at all.

We confirmed that no polyfills or fallbacks are interfering.

This is happening on a custom-built section on this live test page: https://noveltyads.com (it’s a mock client version for internal QA — nothing behind a paywall or login).

Has anyone experienced similar behavior with Firefox’s scroll-driven animations or ViewTimeline implementation?

We’d love to know:

Whether Firefox fully supports ViewTimeline (or still considers it experimental)

Any DevTools flags or settings needed to see scroll animations properly

If there's a better way to ensure cross-browser consistency using native APIs

Thanks a lot for your help and insights!

Hello,

I'm facing an issue where my microphone does not work in Google Meet when using Firefox, even though I’ve granted all necessary permissions. This problem is specific to Firefox, as the microphone works perfectly fine in Google Chrome.

I prefer using Firefox because of its convenient screenshot features, but this microphone issue has caused major inconvenience during important meetings.

Kindly help me resolve this issue.

Thank you.

I am not having trouble signing into any page except FaceBook, I just get a plain white page. I am able to sign in on my phone and a secure browser, but FireFox in my default browser.

I had switched to Firefox from Chrome because they banned AD BLOCKERS. But now I have to go back because FACEBOOK VIDEO CHAT won't work ( according to Facebook) because they introduced end-to-end encryption. Can you give me a fix?

the website onodreamgallery.com shows up as Under Construction, yet on another browser it shows correctly. I do not know how to fix this; I am not versed in Internet language.

Hi Mozilla Community,

I’m facing an issue where my website, [malicious website removed], is not loading properly when accessed through Firefox. It either takes a long time to load or sometimes fails to load altogether, even though it works fine in other browsers like Chrome and Edge.

Could you please guide me on what might be causing this issue? Are there any specific Firefox settings or known compatibility issues I should check? Any troubleshooting suggestions would be appreciated.

Thanks in advance for your help!

Firefox no longer works with my Century Link webmail account. I can get to webmail using other browsers, but I prefer to stay with Firefox. I just checked my Firefox updates and I am up to date. Any ideas? Bob

When I try to sign in to Yahoo I am sent to a Google sign in. I tried that and only got gmail and not my yahoo mail. I can sign in fine when I use Firefox private browsing and Edge. Why is Google involved with Yahoo mail?

I can't log in to many sites in Firefox and have to use Chrome which I hate The IRS site is

What is the problem?

when playing my game the program keeps stopping and starting. Every 7 to 9 seconds while playing my game I get kicked to the task bar and it stops responding for a few seconds and when I click to put it back on my screen and again 7 or 9 seconds I have to repeat the same thing. Bottom line is the gaming program keeps starting and stopping for a few second. This is the only program doing this. This started doing this on June 28 2025 after a new Firefox update. I played this same game on Google and it worked just fine.

Not sure if this is a silly question to ask, but I've noticed that when I use browser Instagram on Firefox it displays emoticons as emojis. For example if I type "<3" (less than 3) it'll display a heart emoji. It doesn't actually convert it In the message though, my friends say it sends what I type.

I'm just wondering why this is happening and how to stop it, I've checked settings for everything and cannot find anything about it. Thank you in advance.

Hi there,

We are using the pigiarniq font family as the web font for a website, it's rendering it correctly in Chrome, MS edge and Safari, but it's rendering differently in firefox browser. There are wide spacings between words if you compare it in other browsers.

I have attached the screenshots below: - firefox.jpg : how the text render in firefox - chrome.jpg  : how the text render in chrome

I am using Firefox version 140.0.2 (64-bit)

Is this a known issue in firefox? and is there a solution to fix the word spacing?

thank you!

Hi, It happened just days ago. The NY times does not let me read articles and tells me I am a bot not a human (I am a subscriber) or that someone is using my IP. I tried everything, clearing cache and data for everything, signed in again to no avail. I tried using a VPN to mask the IP... no success I have no problem reading it on Chrome, but I prefer Firefox. Does anyone have more ideas? The agent from NY times I contacted really was no help at all. Thanks

Hi Mozilla Support,

I'm experiencing an issue when trying to open a specific page on my website in Firefox. The page URL is: 👉 https://ihop-menus.com/ihop-secret-menu/

It either loads very slowly or sometimes gets stuck on a blank screen. I’ve tested the same page on Chrome and Edge, and it loads normally there, so the issue seems to be specific to Firefox.

Could this be related to JavaScript rendering, caching, or some browser-specific incompatibility? I’ve cleared the cache, tried private mode, and disabled add-ons, but the issue persists.

Any insights or troubleshooting tips would be appreciated!

Thanks in advance.

Lately (the last few weeks) Facebook has been getting increasingly buggy and upset on Firefox. General browsing has intermittent speed issues, but in particular opening images off a Facebook page to view will freeze Firefox for 30 seconds or more almost every time, and after a while it usually gives an error about the page slowing FF down. I can close the tab, and if I go to another tab with a different website open then that works normally, but the Facebook tab is dead to the world during this time and doesn't respond to anything except being closed.

Facebook doesn't do this on Edge, and Firefox doesn't have the issue with any other websites, but Facebook now is almost at the point of being unusable.

I've cleared the cache completely, tried debugging mode with extensions disabled, and refreshed Firefox, nothing makes any difference.
