Here is a sample URL that works on Microsoft Edge (current version) and receives an error message on Firefox (115.0.2): https://www.t-mobile.com/home-internet The error received from the web site when using FF is:

Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

FF was working with all T-Mobile pages a few months ago and now fails with this same error on most pages.

To test on Edge, I pasted the identical address that failed in FF into Edge and it worked fine so I am confident I am comparing the same web page on the two browsers.

Thanks for your help. Claude

Hey, this has been going on for a few days, but when I try to use twitter on desktop, there are no retweet/like/reply buttons. This problem doesn't exist on Chrome or the Mobile app. I can reply to things, but that's it. I also can't browse through my notifications without the page immediately displaying the "Something went wrong. Try reloading." message. I'm not sure what's causing this or if it's just me or what.

the website channel 4 wont load and videos wont play on the normal firefox. it was fine a couple of weeks ago. if i load the website in private window, it works fine wiht no issue.

Buttons like 3 bar preferences button, notification etc are broken or not visible just the highlight is visible and click the notification button also break the whole browser

A website I have to use for my work (for the Queensland Department of Education) requires that I input a 6-digit code; for *security*, they insist it be input by clicking on a keypad that scrambles the position of the number keys each time... It's meant to look like the first image attached below, but when I try to open it in Firefox, it looks like the second image and I can't input my code. I'd like to be able to use Firefox for EVERYTHING but I end up having to use Chrome to access this site, which I use pretty much every day for work, and it's very inconvenient.

Hi everyone, When i go to the website config.office.com in firefox there is just a white screen. Nothing more. Instantly white. I have checked if this is an issue at the side of Microsoft but it doesn't look like it is. The website does load correctly in Microsoft Edge.

I tried the following in Firefox: - Firefox is up to date (Version 115.0.2 64 Bits) , I have had this issue in other versions of Firefox too. It's not a new issue in this newest version. - Tried disabling all the security features in Firefox, disabling all add-ons, and disabling the extra security for cookies - Starting firefox in safe mode (Shift click on firefox, then open the website) - Checked the Network inspector. All packets have status 200 (See the first screenshot)

You can check the second screenshot for the white page.

Some help is appreciated :) Thanks!

Firefox 115.0b7 is not correctly handling my system timezone, and using GMT instead. This only happens in specific pages, such as when accessing a website, or in `about:home`. It doesn't happen in `about:config` or `about:profiles`, for instance.

`privacy.resistFingerprinting` is set to `false`. The problem persists in Troubleshoot mode. The issue isn't present in Firefox ESR 102.12.0.

Running `date -R` with the system shell: `Sat, 22 Jul 2023 12:10:42 -0300`

Javascript console at `about:config`: ``` > Date() "Sat Jul 22 2023 12:10:42 GMT-0300 (Brasilia Standard Time)" > new Date() Date Sat Jul 22 2023 12:10:42 GMT-0300 (Brasilia Standard Time) > (new Date()).getTimezoneOffset() 180 ```

Javascript console at `about:home` or `https://example.com`: ``` > Date() "Sat Jul 22 2023 15:10:42 GMT+0000 (GMT)" > new Date() Date Sat Jul 22 2023 12:10:42 GMT-0300 (Brasilia Standard Time) > (new Date()).getTimezoneoffset() 0 ```

I've been watching and following along with a Unreal Engine 4 Course on Youtube for some time now (mentioning in case the resource usage has something to do with it), and in the past couple days I've noticed a pretty serious and annoying bug. When I pause the video, tab (Cmd + Tab on MacOS) into Unreal Engine, do some things, then tab back and resume the video, it will play for one frame and then stop and buffer, but the audio will continue playing. The only way to get the video to resume is to skip forward/backward in the video (either with the arrow keys or the progress bar). I've also tried Troubleshooting/Safe mode and the issue still persits.

I subscribe to The Times (UK) and use many of their different portals. I am, however, experiencing a really odd problem. For the last three Mondays in a row when I hover over a link it shows one destination which is now three weeks out of date and downloads same when clicked. When I Inspect(Q) the relevant bit of script it shows the correct page for the current week. All other links from the current edition work as expected. The link works correctly on other days of the week. The IT support at The Times have no idea why this is happening and have simply asked me to do stupid things like clearing all cache and cookies relevant to their site. this has no effect whatsoever!

How can this happen and have you any help on the subject?

Firefox is displaying a smaller font on some websites. It only does it new windows, not in a private window and other browsers are fine.

Screenshots attached show the correct size (first attachment) and the incorrect smaller size (second attachment).

It's not windows accessibility aka ease of access, as nothing else is affected. All pages are on 100% zoom. I've gone to settings -> font -> advanced and the "Allow pages to choose their own fonts, instead of your selections above" is ticked.

Any ideas please?

trying to open 3d model on this site https://teemo.gg/viewer/league-of-legends/champions/katarina/0 its start loaded model but nothing was showed in browsers based on chromium everything works fine

Hello, this is html code:

<div class="home-page-image-container">
  <img src="https://webdesignleren.com/wp-content/uploads/2023/07/auto-reparatie-in-hoogvliet.webp" alt="auto reparatie" />
  <div id="app"></div>
	  </div>

and this is Javascript code:
<script src="https://unpkg.com/typewriter-effect@latest/dist/core.js"></script>
<script>

var app = document.getElementById('app');

var typewriter = new Typewriter(app, {
    loop: true
});

typewriter.typeString('Home Developer')
    .pauseFor(2500)
    .deleteAll()
    .typeString('Web Designer')
    .pauseFor(2500)
    .deleteAll()
    .typeString('<strong>FrontEnd Developer</strong>')
    .pauseFor(2500)
    .start();

</script>

and this is CSS code:

#app{
  text-align:center;
  font-size:50px;
  background-image: linear-gradient(
    -225deg,
    #231557 0%,
    #44107a 29%,
    #ff1361 67%,
    #fff800 100%
  );
  background-clip:border-box;
   text-fill-color: transparent;
  background-clip:text;
  -webkit-background-clip:text;
  -webkit-text-fill-color: transparent;
  text-fill-color: transparent;
  animation: textclip 2s linear infinite;
}

@keyframes textclip {
  to {
    background-position: 200% center;
  }
}

the typewriter animation with text on chrome,edge,opera is working very wel . only on firefox is not working correctly. I see firefox has some problems with gradient.in this textwriter animation on firefox the first 3-4 letters are not showing and it has strange behaviour. I tried in this way to solve the problem:

 #app {
      text-align: center;
      font-size: 50px;
      white-space: nowrap;
      overflow: hidden;
    }

    #app::before {
      content: attr(data-text);
      display: inline-block;
      width: 0;
      color: #231557;
      animation: typewriter 4s steps(40) infinite, colorTransition 4s infinite;
    }

    @keyframes typewriter {
      from {
        width: 0;
      }
    }

    @keyframes colorTransition {
      0% {
        color: #231557;
      }
      50% {
        color: #ff1361;
      }
      100% {
        color: #ff1361;
      }
    }
 <div id="app" data-text="Hello, Gradient!"></div>

recently, website config.office.com shows blank by Firefox, even for a new fresh OS and install installed Firefox

also, I tried from my different clients, it's the same behavior， no matter Windows OS 11 10, or Windows Server 2016 2019 2022

it's able to load in MSEdge.

One particular website no longer works with Firefox. https://www.familysearch.org/mapp/ I had no problems with this website until a couple of weeks ago. I can use the website with no problem on other browsers. I have tried a clean re-install of Firefox and clearing cache, but still the website does not work. Any suggestions? Thanks John

Just switched to firefox as my default and found that I can't sign in to netflix. It always gives me the "incorrect password" message. I've tried resetting the password, clearing cookies, restarting, turning the DNS proection off, restarting my computer, etc to no avail. Anyone else have this issue or know a potential solution?

Some websites like youtube, twitter, reddit and maybe many more don't properly load. On youtube videos freeze after a couple of minutes, I don't have any of these other issues on other browsers like Chrome

Hi, I've been trying to transfer from Chrome to Firefox but have been experiencing a graphical error with primarily the toolbar in Google Docs. The places where icons should be denoting what each button does are empty - I do not have any extensions, plugins, or themes installed that would be causing this. I did install the Dark Reader extension to see if it would show icons when using it, which it did not. It actually is not exclusive to the toolbar, as drop-down menus that would normally have icons do not either. I tested in both Microsoft Edge and Chrome and this issue does not arise on either.

While Docs has been the primary issue, it persists across all Google Drive apps (Sheets, Slides, Drawings, and more). My version of Firefox is up to date and I am on an HP laptop running Windows 10. If anyone is able to help diagnose the issue at hand or direct me to another support thread where this issue has been resolved, it would be highly appreciated. Thank you so much!

I am having issues with pages on DAX Guide, e.g.: https://dax.guide/now/

These issues are when using Firefox on Windows 10. I have tried with Safe mode, and turning off Enhanced Tracking protection. I have made no changes to Javascript etc.

Issue 1 If I select a code example and try to run it in an external program (e.g. DAX Studio), it fails, and I have found that the reason is because the "space" characters are not ASCII code 32, which is a normal space, but instead ASCII 160. Another symptom of this is that you cannot unindent the paragraphs in a text editor (Vim), if you paste the code there. I have tested and this is not an issue with Chrome, Edge, or Opera. Also if I click on the "Try It" button, it takes you to a runnable version of the code where the spaces are correct. These are workarounds, but why is Firefox using the wrong space characters?

Issue 2 I have seen another response to this kind of question, but it did not exactly answer it: on the website as above, when you click on the "Copy" button, which points to https://dax.guide/now/#, the code is supposed to be copied to the clipboard, however it does nothing. This works without issue in the browsers mentioned above. I have noticed previously on other websites that URLs ending in hash / pound did not work in Firefox. Is this something that Firefox just does not handle, or is there a setting to enable it?

Thanks

Others having resolutions other than 1920 x 1080 are having the same problem. Any help would be appreciated
