Firefox Community Forum

Hi. I am getting vertical lines sometimes. I have included two screen shots. I have checked browser.display.document_color_use = 0, and it was zero. I have tired this in Chrome and it works fine. And I tried in Firefox safe mode, and it still does these strange lines on some websites. I am running Windows 10, and have no other graphic issues except these lines. Websites are Windy.com and google maps. Thanks very much! James

Hello! My name is Anya. I am desperately trying to manage my social media addiction and to help support that I am wondering if its possible to disable the privacy window. I know I can install a website blocker - which I have, but it does not apply to the private window so I have full access to social media on it, I just have to log in. I want to COMPLETELY block Facebook and Instagram off of my laptop. Is this possible? Thank you!

https://x.com/ (Formaly Twitter) Firefox’s Enhanced Tracking Protection (Strict Mode) is known to cause issues on x.com

Not only me: https://www.reddit.com/r/firefox/comments/1ctx1bm/twitter_not_working_on_private_browsing/ https://connect.mozilla.org/t5/discussions/firefox-s-enhanced-tracking-protection-strict-mode-is-known-to/td-p/57432 https://lemmy.world/post/15496431

https://news.ycombinator.com/item?id=40386418 Dunno if entirely accurate but regarding the Firefox error: “Twitter switched their top level domain to X, but didn't change any of their other domains, so they're still pulling assets from Twimg. Which makes Firefox (correctly) block the page if you have Tracking Protect enabled because it sees X trying to involve 3rd parties.“ Slow clap.

My FF version 126.0.1 browser history file size is stuck at 10,240 KB. Until recently it was 54,000 KB and change. I would like to get it larger. I've tried all the recent help postings relating to places.history.expiration.max_pages, places.history.expiration.transient_current_max_pages, browser.history_expire_days, browser.sessionhistory.max_entries or browser.sessionhistory_max_entries, and so on. Nothing seems to be able to change the "places" file size. Anyone have any more info on this topic?

As the title says, it is very slow with Ublock Origin. I have refreshed Firefox and without Ublock it obviously works but I would like to keep the extension because it is the only one that works with Youtube Ads right now.

I cannot print from Firefox. It worked fine, and then stopped. I'm not sure what changed. It doesn't matter what printer I use. Even printing to PDF fails. No errors appear, and nothing shows up in the printer queue. All the other applications in Windows print just fine. It's just Firefox. And just for this one Windows user.

I tried clearing the saved printer settings in the about:support page. I tried refreshing Firefox. I tried uninstalling and reinstalling Firefox. I tried uninstalling, removing the mozilla folder in %appdata%, and reinstalling Firefox. No luck.

The only time I can get it to print anything is to log into a different user account on this same PC. Printing from Firefox seems to work then.

It seems there is some user-specific printer setting/file/whatever that is messed up. I'm not sure what else to try.

Thanks.

I just updated Firefox & added recommended things. I went to "https://www.cranecu.org/" As soon as I hit the LogIn button I got an "Error 404" message. However, I called the office help & they suggested I try another browser. I switched to Safari the button works just fine. Any Suggestions? I am not the sharpest tack in the box when it comes to computers so please be simple. Thank You

I'm trying to import a password csv file generated by Roboform into firefox password editor. I've exported the csv file from Roboform but when I try to import to the Firefox password page I get: "Incorrect or missing column headers. Make sure the file includes columns for username, password and URL". The csv file does have column headings. Is there a way to do this?

I am trying to add an mp4 video to my website using the following code:

<video width="320" height="240" controls>
  <source src="images/###.mp4" type="video/mp4">
</video>

where ### is the name of the video file. I get the following error message:

"No video with supported format or MIME type found."

In the console the following is displayed:

"Media resource http://127.0.0.1:5502/images/###.mp4 could not be decoded. video.html All candidate resources failed to load. Media load paused. video.html Media resource http://127.0.0.1:5502/images/###.mp4 could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_METADATA_ERR (0x806e0006)"

Runs just fine in Chrome and I have no pop-up blockers installed. Autoplay is set to be allowed for all websites.

Windows 11 version 23H2. Firefox version: 126.0 (64-bit)

For a week or better I have been unable to download anything through my Firefox browser, I have refreshed and uninstalled Firefox (I had to reinstall through another browser) in an attempt to fix this issue to no avail. I cannot download from verified sites, nor am I able to download Firefox's own extensions or themes (when I attempt I get an error telling me to check my connection, screenshot included).

I would like to be able to use Firefox normally again, with the ability to download files and install my extensions restored.

When I try to access Developer Community from Visual Studio 2022 ('Send feedback' 'report a problem') the banner displays with selection items but no content is displayed. This has been a problem for several months (years maybe). I now have a problem that I cannot solve and I need to report it and I cannot if content is not displayed.

Hello,

My password saved are deleted every time I close FF. It used to be manageable because Google and other sites didn't require me to fill my passwords (cookies did the trick I suppose) but now I also loose access to gmail and Youtube every time I close FF. It's annoying to have to use 2FA every damn time. And keeping the passwords available.

I've tried every answer I found by looking around :

- tried to start in safe mode - disable hardware acceleration - I have no extensions

FF saves the passwords correctly (at least they appear in the saved password tab) but they are erased every time I restart FF. The cookies aren't automatically deleted (FF remembers my browsing history) but I need to relog into Google.

I getting frustrated.

Hi,

If I have an unloaded tab on right of the current tab and I close the current one, instead of going to the right tab, which is the unloaded one, it jumps to another tab which I'm not sure has what relation to it, it certainly is not the tab that opened it.

I removed every modified entry of "Browser.tab" in About:Config, installed "Select After Closing Tab", no result.

Thanks

Greetings, every so often I'm having an issue loading pages for certain sites that aren't sketchy at all. The most recent one is TireRack.com. I'm shopping for tires for my car and Firefox is loading all the other sites I've visited but it won't load any page from TireRack. They are a legitimate shopping site. It happens from results of a Google search but I've also tried typing the main page of the site's address into the address bar, clicking various other links that display below the actual search result that go to other pages within the site, etc. The site loads fine in both Chrome and Edge. This happens every so often and it's always a legitimate site and the exact same behavior. I can't recall any other specific sites at the moment but it's enough to have me pretty irritated today as when I'm shopping I like to have multiple tabs open with all my options for comparison and price considerations and today I have to have one of them open in a different browser which makes it much more difficult to keep tabs on especially where I'm used to only having one browser open for all instead of having to remember that one of my options is open in another browser. I have glanced through my browser setting as well as my windows security settings but I could spend hours in there trying to figure out things and potentially breaking other things myself, which I don't like doing. Any suggestions or other info on what could be going on will be much appreciated, and thanks in advance.

Ray.

Hello,

I have created a webpage with a canvas element that allows the user to draw an irregular path by pressing down the mouse, similar to the free drawing of a paint application. The issue is that the very first time that the user presses the mouse, the line stops abruptly, while the next times the lines are drawn correctly. The events seem to fire correctly and the page works fine at Chromium, so it seems to be a Firefox issue. You can find the html page below. I am curious, what could be the problem?

<!DOCTYPE html>
<html lang="el">

<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Canvas</title>
  <style>
    #canvas {
      background-color: whitesmoke;
      border: solid 2px brown;
    }
  </style>
</head>

<body>
  <canvas id="canvas"></canvas>

  <script>
    function startDrawing(e) {
      isDrawing = true;
      context.beginPath();
      context.moveTo(e.offsetX, e.offsetY);
    }

    function draw(e) {
      if (isDrawing) {
        context.lineTo(e.offsetX, e.offsetY);
        context.stroke();
      }
    }

    function stopDrawing(e) {
      console.log("stopped drawing")
      isDrawing = false;
    }

    const canvas = document.getElementById('canvas');
    const context = canvas.getContext('2d');
    var isDrawing = false;
    canvas.width = 1000;
    canvas.height = 1000;
    context.strokeStyle = "#913d88";
    context.lineWidth = 2;
    canvas.onmousedown = startDrawing;
    canvas.onmouseup = stopDrawing;
    canvas.onmousemove = draw;

I have to install firefox new everyday on a library computer, (short answer mine was stolen and I can't replace it for now).

Anyway used to have no problem I would go in install firefox sign in and my bookmarks were repopulated. Today I installed firefox and nothing. No bookmarks, no add ons nothing its like a blank install with new profile.

I do not have a backup saved profile on this computer as it is a virtual machine and each day when it shuts down it wipes the programs and data installed. Because firefox repopulated the bookmarks each day when I re-installed it I was not aware I needed to create my own backup I assumed that it was just something in firefox that worked well and another reason why I prefere to use it.

Until today it was not an issue once I signed in everything would re appear but today its all gone. Is there anyway to recover this as it is very important that I do. I use these bookmarks a lot.
