Hi, Not sure if this is the right place but here goes:

Firefox keeps increasing it's tab RAM usage when I change the "src" property of an image programmatically for extended periods of time (1 hour or so).

I created a dummy project here: https://github.com/mvandermade/example-base64-image-memory-high-native

The code above swaps out the image "src" 20 times a second. However I seen buildups with lower frequencies but bigger images too...

Here some measurement of tab RAM usage:

Measurements Windows 10: Firefox 131 00.00h 37MB 01.15h 127MB 03.00h 228MB

Edge (latest) 00.00h 28MB 01.15h 30MB 03.00h 33MB

(Edge seems to have no memory buildup as much)

Here is a copy of the code if the repo ever goes down:

<html>
    <head>
        <script>
        function generateRandomBase64Image() {
            // Create a canvas element
            const canvas = document.createElement('canvas');
            const ctx = canvas.getContext('2d');

            // Set canvas dimensions
            canvas.width = 200;
            canvas.height = 200;

            if(ctx == null) return ""

            // Fill the canvas with a random color
            ctx.fillStyle = `#${Math.floor(Math.random() * 16777215).toString(16)}`;
            ctx.fillRect(0, 0, canvas.width, canvas.height);

            // Draw some random shapes
            for (let i = 0; i < 10; i++) {
                ctx.fillStyle = `#${Math.floor(Math.random() * 16777215).toString(16)}`;
                ctx.beginPath();
                ctx.arc(
                    Math.random() * canvas.width,
                    Math.random() * canvas.height,
                    Math.random() * 50,
                    0,
                    Math.PI * 2
                );
                ctx.fill();
            }

            // Convert the canvas to a Base64 string
            return canvas.toDataURL('image/png');
        }

        setInterval(() => {
            document.getElementById("swapper").src=generateRandomBase64Image()
        }, 50)

        </script>
    </head>
    <body>
        <img src="" id="swapper"/>
    </body>
</html>

Just a observation from my side, if I can help improve things please let me know!

Greetings,

Martijn

p.s. I also created a project in React which gives similar results: https://github.com/mvandermade/example-base64-image-memory-high

I use Internet Bill Pay through my bank, and it has always worked correctly with Firefox. I have enhanced tracking protection turned off for the site secureinternetbank.com and I have cookies authorized in my exceptions list. Today I got this message:

Why can't I access Bill Pay?

You might have cookies blocked or cross-site tracking prevented. Depending on what browser you're using, check your settings for these terms:

Bank says it hasn't changed anything, and no tweaks I tried on privacy settings fixed it. I believe it's an issue with the new version. Can you tell me how to fix it or let me know when Firefox will fix it? The site works fine in Microsoft Edge, but I'd like to avoid using Edge.

Thanks.

I only opened 5 pages (fixed tabs), and only enabled two plug-ins, Proxy SwitchyOmega and AdGuard AdBlocker. The browser was always open, and the pages were static, and nothing was playing. The strange thing is that it didn't take up much memory at the beginning, but it took up more and more memory over time. Today the system got stuck and couldn't respond (it might be that the system used virtual memory).

I used the browser's task manager, which showed that the Shared Web Process memory of several pages was very high, some as high as 4G, and the GPU memory was also higher than before.

I think this is very strange. Why does the memory usage increase exponentially after the webpage has been there for a while?

My settings and usage habits have basically not changed. I didn't have this problem before, but it has appeared in the past six months. I have updated many versions, but the problem still exists. I have always used Firefox. If it continues like this, I will be very disappointed and have to make changes.

I've been using Firefox and Gmail on my PC and android phone for years. Today I can't log into my gmail account on my PC and instead it redirects to google support and goes on about clearing cache etc etc. I have cleared the cache but no different. I have restarted my pc and no different. PC is Windows 10.

I can log in to gmail using Google Chrome so I can't see that it is a Google problem. I can also log in ok on my Android phone.

Is this a Firefox issue?

As the subject says Firefox very suddenly started giving me terrible loading times, despite all the sites working perfectly fine on other devices and browsers. Issue continued with troubleshooting mode, not sure where to go from here. I will open youtube, it won't load about 5 thumbnails, I click on a video and it sets it to 140p and then it still lags the entire video as if I was using 1kbps internet. I tested my wifi connection and its having no problems. Something similar happened when I used to use Opera GX, it was fine for a long time and then one day terrible performance. Please let me know where to go from here. Windows 11 Pro.

Hello dear community! My firefox keeps crashing when trying to open a tab or close a tab. I can't replicate it since it happens on random tab-closing and tab-opening. I think it's just crashing when doing something like clicking anywhere and NOT when doing nothing while the system is idling. Thank you for your help! Here's a link of the crash report: https://crash-stats.mozilla.org/report/index/8ba8940e-954c-4e92-9153-0313d0241001

There's one specific field I fill in very often and for some reason Firefox is really keen on suggesting me two searches that I looked up more than a couple months ago, on a totally different site. I can't even remove these suggestions or add new ones. When I used Vivaldi, it'd learn what I insert (even if it'd end up suggesting tens and tens of options), while Firefox doesn't learn at all.

For sake of an example, let's say that the word I use every day in this field is XYZ. Not even once was it suggested to me, I've only ever gotten the two in the screenshot below instead. And I can't remove them using the Delete key as some other article suggested.

Speaking of which, I just noticed the same thing happen to the subject line in this form 🙃

My Firefox now only opens to a partial page size, not full, even though I click to a full page and then close out.

Opening again just goes to a reduced size page.

I have backed up my profile, uninstalled Firefox and reinstalled and brought my profile back in.

Still the same problem.

I think there is a file that controls this that is corrupted.

Need help.

So, today i opened up my firefox and loaded up youtube; it didn't load. I tried to check my wifi speed on speedtest by ookla...the website didnt work. Then i went to reddit to see if this was a bug affecting everyone anddd that also did not work. So, basically half of the websites that i use do not work right now and i can't figure out why. Everything was fine till yestderday and i havent changed any settings. Also, Wifi speed is not the problem here as i opened up ms edge and everything works.

Please help! Here's a reference image of how websites look ( imgur ) Funnily enough, imgur also did not work of mozilla.
