Hi,

PayPal has a new verification method that involves sliding a bar.

After doing so it says I've been blocked.

I can log in using Edge (but I don't want to have to use Edge for PayPal).

Any help is appreciated.

Picture verification is Not working in Firefox, works correctly in Chrome. This is the verification I have do at some sites to make sure it is me or that I am human after I have not been on a site for long while.

It keeps repeating the picture even though I select all proper pictures. It happens to all sites I visit.

Firefox 139.0.4. version is also not good! Uploading videos to Youtube does not work with it! It does not move from zero percent! As I wrote earlier, the problem started with version 138.0.4. and is still ongoing! Uploading videos works with other browsers! I am waiting for the problem to be solved! If I wrote my letter in the wrong place, please forward it to the authorities! At the moment I could write a letter here, I can't really find a topic where this would be discussed! My OS Win10 64 bit. Thank you!

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!

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.

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 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.

Hello, I subscribe to several substacks and, all of sudden, I cannot like, comment, or do anything on substack if I'm using Firefox. None of the buttons respond. I have tried disabling the ad blocker and tracker blocker (I use Badger and Ghostery) but that did not help. If I use a different browser, everything works fine. Any ideas would be very much appreciated!

https://www.ufc.com/events This website is blocking access when using Firefox. This only happened today 29/06/2025 09:00 hours UTC +8 ( Hong Kong time) It's not blocked when using Chrome. Any suggestions or information will be much appreciated.

The Governor of Poker site gives me an error message when I try to log in with Firefox:

Your browser does not support graphics API "WebGL 2" which is required for this content.

Not a problem with Google, Edge or other browsers.

Graphics Acceleration is turned on.

Any other thoughts?

Hi everyone,

I'm using the Firefox browser (version 128.11.0esr (64-bit)) on MacOS (version 15.5 (24F74)) and experiencing a possible display bug in the ChatGPT website’s project window (as the attached Image-1.jpg shows).

When a self-defined ChatGPT project contains multiple chats, which means the right part of the website page needs to be scroll-able to show all its chats, it seems that it cannot be scrolled using Firefox, and no scrollbar appears. Yet I noticed that the chat list on the left can be scrolled normally.

Besides, I had another try using Chrome, and it work fine there (as shown in attached Image-Chrome.jpg.)

It's quite annoying since I have to switch to Chrome—not my default Firefox—to completely explore all my chats every time. Could someone please verify this and fix it if it is not just on my end?
