Firefox Community Forum

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.

When I startup FireFox, it takes ~15 seconds to show me an page. After loading, it works normal and loads pages within a second, until I completely close the browser, and then the first page again takes ~15 seconds. I've been having this issue for the past few months.

- I tried disabling all my addons - Launched FireFox in troubleshoot mode - Deleted everything in DataReporting\Archived folder - Cleaned out History/Cookies and site data/Temporary cached files and pages - Tried both Default and Max protection for DNS over HTTPS - FireFox is allowed in Windows Defender firewall - Tried setting 'browser.cache.disk.enable' to FALSE - Tried changing 'Enable HTTPS-Only Mode in all windows' to 'Don’t enable HTTPS-Only Mode' - Windows and FireFox are up-to-date

None of the above saw any improvement in loading time.

There is a website https //secure.exeloncorp.com/login that will not load using FireFox. It will load using Google Chrome. Is this a function of the Website or FireFox? Is there a setting in FireFox that will fix it?

Hi, It is not a question but a bug report. From the version 131 up today the Nightly stopped to initialize quickly as before. Certainly, it is not the windows 10 21H2, the antivirus, the firewall or anything other similar internal problem, just because the Edge and the Opera are working fine and they are four times more rapid than the Nightly. It is just to say, that your procedures to improve the security is transforming the Firefox in a mirror of the usefulness Chrome. I take the time to open the home page of Firefox = 9 seconds, against 0.28 s of the Opera. So, I think you should rethink the security and other hidden setting options of the Nightly, because as is, it is very bad. The big thing that the Geeks from silicon Valley did not have in mind is: There are lot of people that need to find extremely fast a configuration, like to export/import passwords from older browsers, or computers, without need to replace one by one. There are many other things that you decided to hide, but I don't know why. Anyway, I will try to update one more time, then, unfortunately I could not use the Firefox anymore. Further, I want a few add-ons, either if there is any percentage of insecurity. A few times we need afford risks to understand and discovery other problems in the web. We cannot do it anymore with the Nightly.

Unable to use Firefox to access Youtube. Problem started either late last night or early this morning. Whether using a bookmark or entering "Youtube.com" manually, the browser window merely acts as if I'm not even connected to the internet before finally just giving up.

Have tried using both 115.17.0esr (64-bit) and 132.0.2 (aarch64) versions of Firefox (each using a different computer), but YouTube refuses to load.

By contrast, YouTube has absolutely no problem loading using other browsers, the site loads almost instantly.

This happened too much, like 6 times when using firefox in this month. I dont want to shut the program because I got unsaved notes in it. I was listening to music and it just began to play it non stop. and it dont respond.

please help, a million thanks!

I try to restart network or suspend the process nothing works. If I could make firefox reopen to it's original state+ cookies; no site reloaded and get back my incogico it would be much appreaciated. ALso everything was saved in firefox since I did not end the task, I dont want to lose those.

Hi,

I cannot seem to close a tab, usually the last one I opened, in my browser window. It remains at the upper left hand corner of the browser. Please note the tab in the attached image.

How do I close this window and prevent this behavior again?

Many thanks,

Lisa D

When I type in the search bar, for example, 3+3 (also tried 3 + 3), when I enter, it will give me this "3 3" and will just show results instead of the calculator.

It, however, still work normally if I were to write "3 plus 3"

Firefox has stopped obeying target="_blank"

Started a month or so ago.

Take a look at Firefox target="_blank" problem for details.

There is not a topic in the dropdown list that remotely addresses this issue so I just selected Performance and Connectivity for the hell of it.

Hi!

I've noticed dropped frames in videos for a while now, but only recently tested the issue. Using youtubes stats for nerds, I found that when videos have a small viewport resolution, it starts to drop frames. (I would test with other sites but only know of youtubes stats for nerds system to detect issues like this) For example a viewport resolution of 1250x703 does not drop frames, however by unmaximising the screen and the viewport resolution drops to 681x383, it begins dropping frames.

Using my 2nd monitor which has a smaller actual resolution, the video drops frames unless fullscreened, see recordings below. Test A | Firefox Maximised but video not fullscreen Test B | Firefox Maximised and video fullscreen This issue also occurs with picture-in-picture mode.

Disabling hardware acceleration fixes this issue but for some reason only affects firefox, using MS Edge with "graphics acceleration" enabled does not result in this issue. Is this potentially an issue specifically with how firefox handles hardware acceleration? Also since I require hardware acceleration to be enabled for 3D model work in my browser, is there something I'm missing here that would allow me to keep hardware acceleration on but not have this issue?

Any help is much appreciated, thanks!

this is supposed to have a QR code, but it does not load. I have attached a still screenshot below.

I also cannot upload images using Firefox to Messenger. The large purple image is a result of an upload, but it should be a picture of a woman saved from Krita.

I tried a setting called "Refresh Firefox" and that fixed it but only for less than a day. whats going on?

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.

Hi, Nvidia RTX Video HDR and Super Resolution works fine when I open a link. But if I scroll the page it turn off. The video still play but the colors changes, I can see that RTX enhencement is then inactive on the nvidia panel. Sometime immediately sometimes after more scrolling. Same on Youtube and Twitch. Any Idea ?

After upgrading to FIREFOX 133 everything became a mess !!

Most pages will RANDOMLY not load and show “Security Connection Failed” message, indicating mostly one of this two errors Error code: PR_END_OF_FILE_ERROR Error code: SSL_ERROR_RX_RECORD_TOO_LONG Additionally and consistently trying to access Amazon makes it think I am a Robot, and shows a page with a Captcha but the images do not load (Image attached) 1Password fails in some pages (Such as CNN), the page shows an error message when userid & password are filled in, rendering it useless. NONE of this happen on previous versions of Firefox or on EDGE with the updated Norton360

I have tried: - Uninstalling, deleting all files and re-installing both Firefox and Norton 360 - Deleting the Firefox profile and starting from zero - Using Firefox without any Extension, it works for a while but then fails (memory overlay issue ?) - Loading a few extensions, again works for a while but then fails. If more trhan 4 or 5 extensions are loaded the problem is immediate (memory overlay issue ?) - Turning off Norton sometimes helps get to a page, and when turning it back on keeps working … Sometimes it does not - - Checked all indicaytions on support article https://support.mozilla.org/en-US/kb/secure-connection-failed-firefox-did-not-connect without any luck WHAT TO DO ?

I have reinstalled Firefox on my Mac many times, completely removed all files using app cleaner, and reset Firefox by holding shift and option on start. Despite this, the app is very slow to launch, and when it does no pages load or render. Opening a new tab freezes the entire app for 15-30 seconds, and when the tab opens it is completely blank. Attempting to browse to a URL does nothing, and the address bar just returns to being empty. Attempting to open settings does nothing, although parts of the app that open separate windows such as the about version info and bookmarks work fine. The only thing I haven't done at this point is completely reinstalling macOS, so maybe there is something wrong with my system config. I first noticed this issue when using the early macOS Sequoia betas, and assumed the app wasn't updated to support it yet. However after updating macOS and completely removing and reinstalling all traces of Firefox, it still doesn't work. I am currently using macOS 15.1 beta, however the issue also persisted on 15.0.

Recently starting having the issue where some whites and the tab icons appear washed out and even glitched out and pink when using my PC. I haven't made any significant changes to my system as far as I recall.

Colours in other browsers and applications are effected. Going to the same webpage on both Brave and Edge shows the whites correctly. On all the games on my PC there are no glitches in colours.

I have tried a few fixes already: -Removing and re-downloading GPU drivers - Fixes the issue temporarily. After about 1 day the issue comes back. -Re-seating the GPU - No fix. -Turning off colour override in Firefox - No fix. -Uninstalling and reinstalling Firefox - No fix.

If anyone has an idea or knows the setting that may be causing this problem I would really appreciate it.

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.

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

The thumbnails can be momentarily seen but within less than a second they disappear. Not happening in edge so doesn't seem to be a computer setting. Cleared all cookies and cache in firefox. No different. The attached image shows the pictures that are missing in firefox. Image taken from an Edge search.

Thank you in anticipation. Steve Balderson
