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!

Any idea why Firefox is not supported on this website? https://mypay.dfas.mil

It's been that way for over a decade. Thx.

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?

Since the update to either 140 or 140.0.1 (not sure because I first noticed it in 140.0.1) the marquee does not scroll in on the page when viewed with Firefox, however it does scroll in Edge so it must be a firefox problem. The site is www.maaccordion.com to see the marquee . It also does not scroll in the latest version (at this writing) of 140.0.2

The scrolling has always worked before and it has been on this page (the home page) for quite a few years. Problem only occurred is one of the updates.

Thanks

Why can't I login into my paypal account in Firefox?????,but if I use Google Chrome,it is not a problem Also On Prime Video,each time I log in(through Firefox) I keep receiving a message about the Browser Is not able to receive HD Videos

Suddenly NY Times links think I am a bot, or there is a java problem, or I am clicking too fast (huh?), and I am being blocked. This started around the same time as the last update. Help! Thanks.....

Since the automatic installation of Firefox 140.0 installed on June 25th, I cann't access at my Bank account and at other professional applications. There is a little padlock that shows off at the bottom of the windows. When I click on this padlock , it shows cookies parameters : only necessary cookies. And I want to let these parameters.

This new version wastes my time. I'm obliged to use Edge navigator.

Hi, for some reason, I am severely restricted in size when uploading files to Facebook, with a maximum .jpg size of under 50k. I do not have this restriction in Microsoft edge, or on my phone, only on my laptop. I do not have an ad blocker installed that I am aware of. Appreciate any help. Cheers, Merv.
