Obscure canvas rendering issue

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;
  </script>
</body>

</html>

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.

I have used Firefox for Windows for many years and have had no problems until recently. I have been unable to print my emails: when I click on the printer icon in the upper right corner of an email nothing happens. I was wondering if there was something in the settings that was causing this problem. Thank you!

I cannot begin to express how frustrating this change is... and I struggle to comprehend why anyone would introduce this by writing it into software, but I'm sure it has something to do with money and profits.

There was a time when you could do a search and get a list of results, and then view a specific listing, and then return to your search page and view another listing. however, those days are evidently gone, as now when you return to your search page, it's slightly different results in a different order. Most are there, but some are missing entirely, and the ones that remain are varied slightly. Whaaaat for!? It is truly a form of torture.

Now in fairness I can't tell if it's the browser (Firefox), or the search engine (Duck Duck Go), because I am unfortunately not a developer. However, whatever is causing it should be fixed out of a sense of social responsibility to the greater good.

If anyone knows why this happens and knows how to fix it, I would be sincerely grateful if you shared the solution.

I am using latest of Firefox and DuckDuckGo. When I type something in the main search bar (in the middle of screen) the text moves to the search field in the toolbar area. I find this annoying. I want to text to remain in the main search bar (middle of screen). Any solution?

For months now I can't cut and paste if I use Firefox. I am not remotely interested is uninstalling a heap of adds in a vain attempt to fix the issue. I can use Google chrome and Wonderfox which don't suffer this issue. I fail to understand why Firefox is alone in this problem. I would switch to Wonderfox as a default but it only works on SSL sites. Please stop ignoring this issue and fix it. Running Windows 11 fully updated on an AMD cpu.
