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.

I can no longer access my local TrueNAS server nor router via Firefox. My current version is 133.0.3. Safari has no trouble. Firefox gives no warning, no Advanced button, no option to bypass security. All I get is: "Unable to connect An error occurred during a connection to 192.168.0.102.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web."

I have tried so many settings, troubleshootings, workarounds, I can't begin to list them. It happens in troubleshooting mode. I have created SSL certificates on the server many different ways to no avail. I'm thinking I will have to abandon Firefox with it's obscure, no-way-through security. But I wanted to ask for help first. Please help.

When I try to make a Google search I get the following message, "I'm not a robot" with a reCAPTCHA: "Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?". This happens on Firefox, but not Chrome or Edge. If I 'Allow' Google in the 'Exceptions - Cookies and Site Data' then I do not get the message, but it takes several seconds for Google display the resulting page. However, if I delete the cookies/cache the message will return and I have to redo the reCAPTCHA. I have scanned with Malwarebytes, Bitdefender, Hitman Pro, Trend Micro House Call and Microsoft Defender, nothing detected. Running Win 10 (64) with 'Extended Security Updates', Firefox 147.0 (64), no additional Extensions or Plugins. Also I uninstalled and reinstalled Firefox.

'bold text YouTube is "acting insane, sound plays/picture is frozen. Can't pause it. Also can't start it! Ads play on without option to skip. I got some notice that YT was changing something, I think it is broken. I managed to get a video to play on MS Edge, but I normally do not use that. I cleared cache and ALL of that, rebooted computer, etc. connection is good. Searches are fine on firefox, Other sites are fine on firefox. . IT IS YOUTUBE! It is SO bad that now with my mouse, the arrow and hand are NOT showing up on the actual screen where video plays. Right now on here it is fine. but on youtube? no.

after the last Firefox update the zynga game Farmville 2 will not load. It gives me a screen to fix mentioning chrome..but all efforts to manually fix referencing Firefox have failed. Odd that I can load the plain Zyngagames.com on Edge but it seems they too only load a "local" game that is not connected to any network. Help also mentions to make sure I allow to redirect but that "Options" feature to do so is not there. In fact it seems like the Firefox menu system is even much different and expanded. I will add the screens I have tried etc. Pop ups are allowed, turned off enhanced etc. but cannot find any reference to "third party redirects" Any suggestions are appreciated.

ATT.NET is blocking my access to ATT/Yahoo email from my ATT.net account using Firefox ''but not using Chrome?'' I have stopped all tracking and cookie blocking

I recently installed an rtx 3060 12gb on my old system (Win10, ga-h77-ds3h gen3 mobo + xeon ivy bridge cpu). I installed latest Nvidea Studio drivers. Everything seems fine apart from Firefox, which showed visible artifacts/flickering lines on the screen. I disabled hw acceleration in Firefox settings and now instead of the lines I just see micro dots which change position frequently. As recommended by AI i changed some other settings in about:config but the tiny dots are still there. Starting Firefox in safe mode they are still there. On MS Edge its fine, there are no dots/artifacts.

Is there something else that might fix this or there is nothing that can be done, its just how the rendering engine works on older systems and rtx 30s cards?

I updated firefox through apt, and since then, have not been able to log into twitch I am on ubuntu 24

apt list --installed | grep firefox firefox/mozilla,now 144.0.2~build1 amd64 [installed]

Attempting to log in returns the generic "Your browser is not currently supported"

Hi,

I started to notice recently that calendars in some websites I browse with Mozilla are inaccurate. The dates like months, days,... are in a mess. Then I used Google Chrome instead of Mozilla and it went right. It was accurate with Chrome browsing those sites. Did you hear of the same problems with Mozilla ? What can be wrong ?

Thanks for your insights,

All the best,

Denis

I'm afraid I picked up malware despite Sophos due to this message upon routine searches, e.g. "Where's the nearest pet store". About this page Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?

It's preceded by the reCaptcha request to check the box stating I'm not a robot.

When signing in to online Shaw Webmail, message says 'Security Check Failed. Clear your browser cache and retry'. Screenshot attached. Have done so in "Clear browsing and data history", (as per Firefox guidelines) multiple times, for all History and cache. Did not resolve issue. Contacted Shaw Support; they instructed to try logging in with Chrome browser. Worked fine. Issue appears to be strictly with Firefox Browser (on multiple devices). I prefer Firefox over Chrome. Any advice greatly appreciated.

Hello,

For few days, it's impossible to connect to FACEBOOK. I have the latest version of FIREFOX, but I have to use another web browser (EDGE) to connect to FACEBOOK. The problem is the same with my two computers with the latest WINDOWS.

Thank you for your help to solve my problem

The app sizes two adjacent images to the same height. Maybe there's a better approach?

This works, in that I see the original image displayed at the wrong size:

   //img.src = imgsrc.src;

This sizes the image but without the data (black square for toDataURL w/ image/jpeg) in FF, but not Chrome and Safari:

   var canvas = document.createElement( 'canvas' );
   canvas.width = width;
   canvas.height = avail_height;
   var context = canvas.getContext( '2d' );

   // Tried/failed: Fill white background for JPEG export
   //context.fillStyle = '#fff';
   //context.fillRect(0, 0, canvas.width, canvas.height);

   context.drawImage( imgsrc, 0, 0, canvas.width, canvas.height);
   context.lineWidth = 150; // ??

   img.src = canvas.toDataURL('image/jpeg', 0.92);
   img.onmousedown = disableDragging; // for FF
   img.style.opacity = "1.0"

The page is the view.html one gets to via Enter on phobrain.com.

I am using Firefox 149.0 (64-bit) with Yahoo.Com as my home page. All of a sudden, when I use the search bar at the top of the Yahoo Home Page, Firefox opens up a blank tab in response. Doesn't matter what I search for, same thing happens. Then, if I close that blank/empty tab and reattempt the same exact search again, it works fine.

This has been happening only for the past few days - was fine before. Is this Firefox? Or is this Yahoo? And how can I resolve the issue?

Thanks in advance.

The errors I get are kind of all over the place though. I've completely deleted and reinstalled Firefox, and removed all extensions too.

It will loop to the login screen over and over, or I get the message 'An error has happened, try again later'...

I used the browser console and didn't get anything that seemed usable. I use Strava nearly every day so I'm having to use Safari. And this issue is on all of the mac and Windows systems I use. 'Troubleshooting Mode' didn't work either.

Help!

I'm experiencing problems across numerous sites using the above version of Firefox, detailed below. Other browsers are OK, as are other versions of Firefox on different devices.

Outlook365 email - "Your message can't be displayed right now" Fantasy Premier League - unable to log in, hitting 'Log in' doesn't respond Faceboook - content does not load Ebay - html on formatting in listings is screwed up Duckduckgo non-functional - returns the message "Ugh, it happened again! The server encountered an error and could not complete your request." The Guardian - images do not load Nextdoor - messages do not load

I have messenger loaded but with Firefox i can not video call when i want to call a friend or family. I have no way to call any one i do have a web cam. do i need to go to Chrome every time i want to call. Messenger has stopped desktop messenger that was how i could call but now i can not is there some way to Facebook video call on Firefox please let me know thanks I want to stay with Firefox why is there no way to get video calls on Facebook??

Google has added some AI 'ads' to their title page? This just appeared a day or so ago on my system. How did I remove it, block it? Attached is an image of what I am asking about. What is interesting is in Chrome I can explicitly turn this junk off. But when using the Google search title page with Firefox, there appears to absolutely no way to disable it... very nasty way of forcing you to use Chrome?

Moderator note: Edited per OP's request.

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!
