Why when you click on the extensions button (jigsaw puzzle icon) in the toolbar to open the extensions panel the “Personalize Your Firefox” screen appears ???

When you right click a gear icon in a particular extension, the drop down menu has no "pin to tool bar" option, it only shows "copy/select all/print..." options ???

Thnak you.

Yahoo Mail won't open. Saved Yahoo Mail at bottom of page says "No internet connection" but work even though other apps and bookmarks open and recent Yahoo Mail saved at bottom of page opens when I click on it. Have most recent version Version 115.18.0esr 64-bit? Restarted Firefox but still won't open Yahoo mail bookmark.

Why are there 20 to 30 instances of firefox in my task manager when I have just 2 tabs open? It is bogging down my old laptop. I got directions to fix it from Mozilla Support, by turning off recommended performance settings and lowering content limit from 8 to 4 [although directions said I could do that right there, but I couldn't and had to go to config.] After a restart, I currently have just one tab, and there's 12 firefox, and it had gone up over 30 originally. I did a whole bunch of end tasks, but they keep coming back. Why can't I force it to only open 1 firefox for each tab? I don't want all that extra crap!

please forgive me for asking again, but I REALLY need my addons to work. Firefox disabled my addons, forcing me to upgrade to a version of firefox that I don't need, since the old one was working just fine. The new version does not seem to appear to have downloaded properly, and neither version is allowing my addons to work or be re-installed. Please explain it to me like I am 5 years old, and help me to get this fixed without losing any of my info that might be stored in the addons.

 Thank you.

Firefox is not accepting any addresses:

Hello, I have the following problem.

First, Firefox wouldn't start at all. Then I undertook the following repair attempts:

Uninstalled and reinstalled Firefox, keeping the profiles during installation - still won't start. Uninstalled and reinstalled Firefox, not keeping the profiles during installation - still won't start. Uninstalled Firefox and deleted the entire AppData\Roaming\Mozilla folder (backed up first) - it starts. I have always uninstalled via the Windows Control Panel and downloaded (multiple times) and installed the latest version of Mozilla.

Now Firefox is not accepting any addresses. Additionally, it doesn't respond to any commands in the upper area: plugins, settings, etc. do not respond when clicked.

I uninstalled Bitdefender and also turned off the firewall, but it didn't help. I don't know what to do anymore. Can someone please help me?

Specifications:

Processor: Intel(R) Xeon(R) CPU E31245 @ 3.30GHz RAM: 16.0 GB System Type: 64 Bit Windows 10 Pro Version: 22H2 OS Build: 19045.5011

All my other browsers work fine but since April 4, 2025 Firefox won’t work at all. Websites won’t load. I have tried to clear my cache & cookies, I have checked my connection settings, I have checked for malware, I have turned off all my extensions and I have completely restarted my computer several times now, nothing has worked. I also did trouble shoot mode & reinstalled Firefox (though I will admit I maybe didn’t do this step properly). I refreshed Firefox. Why is it not working? What happened? I don’t know what to do as I don’t want to lose all my bookmarks and passwords that I have yet to move over to my password manager. Please help.

As of the lastest Firefox upgrade Pinterest is completely broken. When I log in the home page loads, but all instead of pictures I see colored boxes. The only images I see are the animated ads, they show fine. In other words, the opposite of what I want. I am only using adblock origin as an extension. I have cleared website data, clicked the shield to stop blocking, and rebooted firefox in safe mode yet the problem persists. Every other browser I have can show pinterest just fine. Safari and Chrome have no issues, only Firefox. I am using Firefox 131.0.3 on MacOS Sonoma 14.7.

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 need to revert to the prior version - my Firefox updated automatically and now there's a bunch of stuff that make using it very hard for me.

Background - I have a TBI that limits my ability to process input. This new version has dropdowns on tabs that are useless and extraneous and make it hard for me to find what I need. I want the old version back so I don't get confused.

I got one response to my prior inquiry with some words and stuff that didn't make sense and when I tried to follow the "directions" what the response said would happen didn't. I tried to restart the search for how to fix this so I can function but it's been ignored for 5 days now.

CAN SOMEONE PLEASE TELL ME HOW TO GO BACK TO THE PRIOR VERSION which was working just fine PLEASE???

Since the recent update to Firefox 131, I can no longer use the Billpay option of my TD Bank account. I am able to log into my account without any problems and use all of the options except for Billpay. I want to add that I know I am not alone with this problem as I have seen several others with the same problem but with different banks. It is the Billpay option which no longer works.

As I said, the bank site is fine until I click on "Billpay", Then I get this: begin quote: "Why can't I access Bill Pay?

Здравствуйте. Что произошло с браузером. Почему не загружаются страницы, а открываются те, которые открывались когда-то раньше? Мне сейчас постоянно жать на кнопку обновить страницу? Что вы сделали с браузером???

Used to be able to access my Xfinity account on FireFox. Now, when I try to log in (after I type in User Name and Password and hit "Enter",) I get a blank screen except for the words: "a rendering error occurred: ." in the upper lefthand corner of the screen.

I am using a MacBook Air running Monterey 12.7.6.
