macOS 15.6 Firefox 141.0.3 - my preferred browser

I've seen a number of posts regarding this problem since the Firefox 141 update. I've tried a number of suggestions, although my problem seems slightly different.

I can apparently login to reddit OK but when I try to access a subreddit thread, a warning comes up - see image.

I have cleared Firefox site data, cookies, cached files, etc - problem remains.

I have restarted Firefox in Troubleshooting mode - problem remains, so not an extension.

However, https://old.reddit.com has no problems with Firefox, lets me access threads, etc and comment.

No problems accessing reddit with Safari or DuckDuckGo browser.

Firefox is not allowing me to login to Reddit.com. Nor can I create a new account with Reddit.com with Firefox.

I can login fine with Microsoft Edge. I don't want to use Microsoft Edge.

I can login fine with Chrome. I don't want to use Chrome.

What's Firefox's problems?

moonpupy@outlook.com

new install of firefox won't load accounts.firefox.com

other browsers on the computer load it fine

I've imported bookmarks and passwords and stuff, and since refreshed firefox but can't find a way to fully restore it to initial settings, even uninstall and reinstall won't do it

I don't know if this ever worked in FF, since I've been on Chrome a while. I tried canvas.toBlob() in FF without a solution.

The behavior is the same whether the served image is jpg or webp. A Servlet delivers the image data, here in webp:

          response.setHeader("Content-Type", "image/webp");

On page, I use a canvas thus => see '// FIREFOX'

     var canvas = document.createElement( 'canvas' );
     canvas.width = width;
     canvas.height = avail_height;
     var context = canvas.getContext( '2d' );
     context.drawImage( imgsrc, 0, 0, width, avail_height);
     context.lineWidth = 150;

     // FIREFOX: canvas.toDataURL('image/jpeg')=black, png,webp,default=transparent
     img.src = canvas.toDataURL('image/jpeg');

     img.onmousedown = disableDragging; // for FF
     img.style.opacity = "1.0";
     console.log('setImg ok');

Inspecting a black jpeg:

        data:image/jpeg;base64,...

Thanks!

Last week we lost the progress bar at the bottom of videos on Prime Video. When I cursor over the bar it returns Infinity:NaN:NaN. Switching to MS Edge and the progress bar appears as normal. I get the same results in Firefox on both my PC and Laptop. I have updated and reinstalled Firefox to the lastest version. I have NOT added any new extensions in the last year.

I searched the forums and found a few similar entries but i couldn't see any solution so far. Whenever i try to open my inbox the page initially loads and shows the progress bar but after the progress hits 100% it just hangs there and nothing happens. See screenshot please. Gmail works normally in other browser (MS Edge) and my Android phone. I've been experiencing this issue for more than a month now. Not sure exactly when it started. Probably with v134. Installing v135 fresh didn't change anything. This is one of the most persistent issues i've experienced about browsers. I use Avast AV but all browser modules are disabled + web shield disabled.

So far i tried these steps to no avail: - Clear cache and history - Clear whole site data by using "forget site" feature - Clear cache and cookies using the padlock icon next to the search bar - Disable/enable hardware acceleration - Disable/enable javascript (gmail requires javascript to work anyways) - Disabled all add ons/extensions, tried safe mode - Reinstalled firefox after uninstalling and deleting any left over folders

My system specs: - Windows 10 pro 22h2 x64 - ASrock B450M HDV R4 Mainboard - AMD Ryzen R5 3600X CPU - AMD RX 6600 GPU - 16 GB DDR4 3000 RAM, 250 GB M2 SSD

Dear Helper,

since the newest Firefox update, i got today (16.09.25), the audible cloudplayer doesnt work anymore, meaning it wont load the audiobook! I emptied the cache, but nothing changed. I tried the audible cloudplayer with Windows Edge and it works fine, so it is a Firefox specific problem. I granted all websides access to audio and media automatic replay, nothing changed. The cloudplayer doesnt work! So my question is: What else is interfering in Firefox with the loading of the player? Thank you so much in advance for your help :) Yours sincerely David

Hello,

This started happening recently, in the last 30 days. Gray screen is shown when I clink on any photo in "Your memories from this day" email from photos@onedrive.com. If I go to OneDrive, then select today's date the issue is the same.

I've tried the same actions in Chrome and the photos are shown without issues.

Can someone help with this?

Regards, Petar

Recently, after the newest Windows 11 update, Twitch hasn't been loading correctly, the tab looks as if it finished loading, but the page gets stuck in endless loading, no other site has this problem, and it happens even opening links to Twitch channels directly. I've added and screenshot of the problem.

I'd love some help or at least know if this is a problem on Twitches end or not. Thanks.

I am blocked from opening my Asus Router in Firefox for Mac. I added the router's address to every exception list I could find in Settings and still no luck. I can reach the router through Safari and through Firefox and Edge on a Windows 11 machine. I like my present Security settings on my Mac except for this annoyance. Can anyone suggest a workaround or a setting change that would fix this issue? Thanks in advance for your help.

Since the Tahoe upgrade I can't login to my google account because the 'Passkey' prompt that the system is supposed to automatically trigger, never eventuates as it used to in Sequoia. I am signed into my account on the same desktop using Safari but my preferred browser is Firefox, so this is quite frustrating.

After upgrading my 128 esr to 140 esr, some sites stopped opening. In regular versions, it has not opened for a long time. There are many such sites, for example, qwen3.app or temp-mail.io. It thinks for a long time and finally a message that the time has expired. Chromium is ok.

I'm get an Access Denied for a web-site I have frequently accessed. Only Firefox on my laptop has this issue. Edge and Chrome are able to access the web site. Firefox gives me the following error:

You don't have permission to access "http://www.nfm.com/" on this server.

I have cleared my cache and data and cookies and nothing works. Able to access it from my phone's firefox browser.

Just recently I have found that certain sites are unavailable to me using Firefox but I can access them using Edge or Chrome. One particular one is Squarespace.

Is there anything known - how should I tackle this?

As of 7/10/2025, Xfinity Streaming does not open through Firefox. I much prefer Firefox to any other browser so I am a little mystified as to why all of a sudden Xfinity Streaming does not open. I receive my Comcast email through FireFox but when it comes to streaming content, the Xfinity logo just sits there and does not open.

I try to connect to gpx.studio and I get the message

"WebGL 2 is required to display the map."

then "Hmm. While your browser seems to support WebGL2, it is disabled or unavailable"

However, when I connect to the same site with Chrome everything works and the map is displayed.

What can I do ? Is it a problem of graphic card blocked by Firefox ?

Tried to file my Federal and State taxes using Turbo Tax which I have used for years. I am using the Turbo Tax on line app for Windows 11. Was unable to complete the filing because of many error messages. Turbo Tax tax experts suggested I switch to Chrome. I followed their suggestion switch to Chrome and was able to complete the filing of my Federal and States Taxes with no issues.

Why can't we use Firefox to file our Federal and State taxes?
