Diễn đàn hỗ trợ Firefox

Myself and a colleague who both use Firefox on Mac are experiencing the exact same issues.

1. Table header cells don't show their text, unless we specify a font for the table

I tried to put an example of the HTML here but it was rendered as a table by this page. I'll add some images of the code instead to show it.

In Firefox the Header cells are not visible, but in Chrome the text appears correctly.

If we add CSS like...

<style> table { font-family: Arial, Helvetica, sans-serif; } </style>

...in the header then the missing text in the THs appears.

2. Other font issues

The Wave accessibility extension has text that doesn't appear and throw errors like this in the console...

downloadable font: rejected by sanitizer (font-family: "Open Sans" style:normal weight:400 stretch:100 src index:3) source: moz-extension://b86260c9-33f6-4529-b12f-a101d8607bd4/styles/open-sans-v17-latin-regular.woff

These only occur on Firefox on our Macs. Fine on PC and other browsers on the Macs.

We tried a whole series of tweaks to settings to try fix this.

I have tried resetting Firefox and doing a fresh install but nothing fixes either issue. Are these known issues with recent Firefox releases on Mac?

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

"Something's gone wrong We may be having trouble with your connection. Connecting your device to Wi-Fi could help fix the issue or try again later. If you were using an app, close this page. Otherwise, start over."

Again ONLY in FF harbor freight search function breaks when entering a search.

Yes, please don't give me the MS ctrl-alt-del type of response about cookies.... That was done many times before posting this. The website works fine in Brave. MS Edge well, let's not speak of it in public company shall we.

So, now what the heck is happening to FF???? I have contacted HF three times and they referred me to use other browsers other than FF. No, I DO NOT have multiple extensions nor themes. FF is bare bones but for uBlock. Hardware acceleration is off and MS Clear type is on. Anybody wanna fess up, who broke this????

I am using the Firefox browser on my iMac. Suddenly, I am not able to 'sign in' or access pages of common websites. I am getting blank pages or pages with the ever-circling ball when trying to access websites, like homedepot.com, shutterfly.com, etc. I can access them via safari.

I have gone through the Troubleshooting steps, have Uninstalled Firefox and Reinstalled, etc. What is happening with my browser?

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.

Hi!

Please see attached image:

Left: Edge (making sure it isn't a network issue)

Right: Firefox using a new profile from about:profiles.

On my main profile, I've tried clearing the data and cookies (though not the history) a couple of weeks back.

Any suggestions welcomed! Many thanks in advance.

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.

Some web sites such as Amazon have an options bars to select items like 'review order'. When the web page first comes up, they show white in the dark bar. But Firefox is immediately changing the white to purple so that it is almost impossible to read. I haven't been able to find anything in settings to correct this. I do not have this issue when I use Chrome.

When logging in to a website that I use many times every day all day, all of a sudden I log on and all I get is a blank white screen. I have tried clearing everything, restarting Firefox, removing Firefox and re-installing it, rebooting the computer, starting Firefox in the safe mode but no change. The same problem shows up on three different computers on two different networks with two different ISPs. The website opens normally on Edge and Chrome. I would prefer to be able to use Firefox. Using version 139.0.4 (64-bit) on all three computers. I would really appreciate any help that is available.

On all our computers it seems impossible to sign into Outlook...several laptops and 3 desktop...even a new Apple device. Enter your email address and then taken to the next page (see attachment). sign in works with Edge! This has been happening for maybe a month. Very frustrating! NEVER opens the next security window, the 'spots' just keep moving forever...selecting "Back" just repeats the cycle.

Dear colleagues, please tell me what could be the reason why the Google AI Studio is not displaying correctly. The buttons are invisible, the fonts are stretched, and it's generally impossible to work (see the attached screenshot). Please refrain from giving advice like "update Windows to a newer version," as this is an old computer (its motherboard was manufactured in 2007), but it still opens most websites fine. I don't currently have access to a newer computer with Windows 10.

Hello, since I installed the Firefox 141.0 update today, I can't login to Reddit. I tried logging into Reddit right after updating Firefox, so did a System Restore to see if that corrected the problem, and it did.

To double check, I installed the Firefox 141.0 update again, and encountered the same problem logging into Reddit again, so it's definitely this new update causing the problem.

I've attached the Reddit messages I get. The 1st is the initial message, and the 2nd after I retry logging in.

I would greatly appreciate help with this.

Thank you,

Michael T.

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.

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 received this message from ATT whenever I try opening my email: "Something's gone wrong. You may be having trouble with your connection. Connecting your device to WiFi could help fix the issue or try later again." However, I can get into my email through Chrome with no problem so I'm able to continue working. Would uninstalling then reinstalling Firefox help without creating more problems? I would like to continue with Firefox if possible. I have Windows11. Thank you.

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.

I used to have an occasional sound problem with FF, usually felt when YT clips could not be heard any more. I mean to remember that it could be fixed (until next time) by restarting the file explorer somewhere in Task Manager - not a convincing solution but one I could live with.

Today, there's a new situation. Again, trigger was the missing YT sound in FF - not in fx Edge, and that the Task Manager trick didn't work (or maybe I restarted the file manager in the wrong tab?). Looking for a solution, I happened to see that the YT mute function in the FF tabs seems to be gone. However, other sounds are affected likewise. Also, I can't see them in Edge either. After various restarts (or maybe something else I did, instigated by the various instructions I found?), the sound is back.

However, while continuing to pursue possible solutions, I also happened to find that my browser is being 'administered by my organisation' - what ever that means (see two annexes). Who did that? I would say, this is not something I did, I would prefer to see it gone. But how? Will the other browsers (which I keep as a spare, and that I'm hardly familiar with) be likewise affected?

This is an equation with too many unknowns for my limited knowledge, are such effects known? Would there be an approved way-out for it?

PS I have checked https://support.mozilla.org/bm/questions/1412934 especially the message posted by lazizakhmedov1014, and do not see this to apply to me - short of a reinstall - FYI
