When i start fire fox it immediately opens 10 additional versions in the background which I can see in task manager and they take up a lot off memory. If i end task them they immediately come back. This only started recently. I noticed it because now when i open say a youtube video it shows it as number 4. This never happened before unless I had the same video open more than once.

If I can not stop this I will have to uninstall.

When I go to another app, and back, tabs have to reload, often loosing what was done in the page. I have set Firefox as "No restrictions" on my Xiaomi 15 Ultra (HyperOS 3, Android 16), but Firefox still seems to unload memory very frequently.

So either firefox or android (probably firefox) just updated, and it's made a mess of the browser. First of all, the layout of everything has changed - the traffic light menu's at the bottom of th e screen now, completely different, there's a pull bar to see stuff that was previously readily available, the tab icons are longer for some reason but I think they're also skinnier? The hell? It's just generally worse than what it was before. I hate every part of it and want it rolled back on that basis alone, because I actually liked how it worked before, and if I want to change how my phone works I'll do it myself. Stop messing with my stuff, mozilla, I don't come into your house and start moving all your furniture around and putting your cutlery in the wrong drawers, and I'd appreciate it if you returned the courtesy.

But, as annoying - read, infuriating and unnecessary - as that is, that's not the real problem. Oh no. No, that's a personal issue, I'd either learn to live with it or I'd find a modification workaround to get my old UI back. No, the problem is that my previously smooth tab screen - you know, the one where you can see all your tabs open - now lags. Noticeably. How do you mess that up? Seriously, what did you do? It freezes when I'm scrolling up and down! How! How do you do that!

In summary, update bad for UI reasons (please stop moving things for no reason, or at least give us an option to move it back, some of us hate that Really Quite A Lot, to the point where we left chrome over it) but also for previously-nonexistent latency where there absolutely should not be any. I'm on a Fairphone 5, this isn't an ancient brick that barely runs. How do you update something to be actively less functional? Please just roll it back. And if you only take one bit of feedback from me ever, stop touching the UI. It's really annoying. Please. Just don't.

Even with just 1 tab open, Firefox is killing my laptop battery.

Win 11 PC laptop.

In background, it is using 40% to 50% of the laptop battery. I need much better performance from it. I have already turned off any settings I can find regarding Firefox's background functions. When I quit Firefox I want it completely off.

How can I do that?

STOP STOP STOP STOP STOP STOP STOP page reloads after losing and regaining focus! This bug makes it impossible to use FF for any tasks that require external authentication and is simply incredibly annoying!

A couple days ago, some weird issues have started:

• All my bookmarks are gone
• Any of the buttons in the UI that open a smaller UI do not work (such as the 3 bar menu)
• Similarly, right clicking to open a menu (such as "Save Image") also does not work
• Any dropdown menus in websites seem to also not work. For example, in this very support page, I could not select an option in the "Which topic best describes your question?".

I can't restart and troubleshoot Firefox since I can't access the 3 bar menu.

So out of nowhere, I can't use the back button, or delete pages by clicking the 'x. I can't even click on the settings icon, or any icon on the menu bar. When I hover over any web page title, it shows a small window of it, but I can't get rid of it. I didn't change anything, so what's going on?

Dear Firefox Support Team,

I am writing to report an issue I’ve been experiencing with Firefox on my MacBook Air (M3, 8GB RAM). Recently, Firefox has been becoming unresponsive quite often, and the Activity Monitor shows significantly high memory usage. For context, I typically have two Firefox windows running simultaneously, with approximately 5 tabs open in each window (10 tabs total). This is when I notice the performance degradation and high memory usage.

To help you investigate, I’ve attached:

• A screenshot of the memory usage in Activity Monitor when Firefox is running.
• A screenshot of the extensions currently enabled in Firefox.

I am open to suggestions, such as disabling or removing certain extensions if they might be causing conflicts. However, I wanted to report this issue first to understand if this is a known problem or if there are optimizations planned for Firefox on Apple Silicon Macs.

Let me know if you need additional details, such as Firefox version, macOS version, or specific steps to reproduce the issue. I’d be happy to provide any information that can help resolve this.

Thank you for your time and assistance. I look forward to your response.

Best regards, Hemant

The minimize, maximize, close line at the top of the screen is missing when Firefox opens. If I click the Firefox icon in the task manager to minimize it and click it again to maximize it, then the missing line at the top appears. This has been an ongoing glitch for a week or more. Perhaps you can fix this minor problem?

Having heard the news that Firefox's latest CEO wants to turn it into yet another AI-slop browser, I came to this forum to give feedback as an avid Firefox user over the last 4-5 years. I can see I'm not alone either; there are tons of other users who seem to feel the same way I do.

This is a very, VERY bad decision. So far, every "AI update" that has already hit Firefox has done nothing but make the browser worse and more inefficient. A few months ago, Mozilla was getting hit by complaints from desktop users about memory usage skyrocketing due to the implementation of an AI chatbot into Firefox. Now they've added AI search engines among other things. And surprise, surprise--no one seems to actually want to use these features. Why should we, if all it does is make computers run slower, overheat, and doesn't actually answer any useful questions or contribute anything meaningful?

I'm baffled at Mr. Enzor-DeMeo saying he wants to go all-in on making Firefox an "AI browser" with his whole chest in the SAME week that Microsoft has had to lower their growth targets for AI-related sales, some of them up to 50%, because NO ONE seems to actually be buying AI products. You know, on account of (you guessed it) not finding them very useful.

Other people have already mentioned the myriad of other problems with AI too, so I won't touch on those too much, other than to agree that AI is a plagiarism machine that's doing serious environmental damage. What I WILL say is that I personally have been using Firefox all this time specifically because it's avoided the AI craze as much as other browsers, or at the very least, avoided making it "opt-out" instead of "opt-in" to the same degree. But if this changes in the near future and Firefox does become yet another inefficient AI slopfest of a browser, I may seriously rethink my loyalty to Firefox and switch back to Chrome instead. After all, there would be functionally no difference between the two browsers anyway!

Please rethink this decision and consider actually listening to user feedback going forward. If Mozilla actually wants to retain their userbase, I'm sure I'm not the only person thinking about dropping Firefox for Chrome in the future.

Please stop adding AI to your browser. It is making it slower and is a data privacy concern for me as well as many others. If you do not remove them I will be switching browsers. AI is not only bad for the environment, it does not even do the features you want it to do correctly. Please remove AI from firefox, i have been using this browser for years and would hate to leave because you refuse to remove AI features nobody asked for.

I can complete the sign in and enter my password, and then I get a spinning wheel and can no longer click on the tabs or minimize the window. I have to force close it and it shows as not signed it. I've also tried signing in using my phone and the QR code, same thing. This happens with or without 2FA, I turned it off and the issue persists. Everything else about the browser works completely but I can't sync across devices without the Mozilla login working.

What causes Firefox to freeze when two video windows are opened, i.e. in a new tab, the video windows immediately start to freeze? I use Windows 11. Other browsers work fine, only Firefox freezes with two windows open.
