Firefox 社群討論區

I recently got a new laptop with Windows 11 Pro. I installed Firefox from the Mozilla site. When I click to open Firefox, it takes a long time - 41 seconds to be exact. I uninstalled, reinstalled and restarted my computer. I cleared the cache. I tried to run as administrator. Not sure what else to try. As I wait for it to open, it reads "not responding" in the search bar area. Any ideas?

I use Brave, Firefox, Firefox Developer Edition and Thunderbird. Brave: 600mb Firefox Dev: 600mb Thunderbird: 200mb Firefox: 800mb Why is Firefox using too much memory? Especially as I am running Firefox Dev as a direct comparison. I don't have any plugins on Firefox. Firefox Dev has uBlock Origin alone. Brave has a few plugins.

On my Windows 11 IOT Enterprise LTSC system firefox does not entirely close. After I installed my professional tax software from Drake Software LLC the following happens repeatedly: I open Firefox, look at a page, close Firefox, the screen clears and when I try to REOPEN firefox a popup says that it is still running and offers close or cancel. Neither button opens,closes or cancels Firefox. I have to reboot to make Firefox (147.02 64bit) close. This happens every time I open Firefox.

In Firefox's Task Manager, how do I know which tab is using which subframe(s) process?

For example, let's say I open Firefox and with only one single tab open, I open the following web page: https://audioplugin.deals/product/best-of-zampler-collection/

That page apparently includes content from several third-party websites because when I open it, Firefox's Task Manger shows processes for the following:

https://audioplugin.deals https://cloudflare.com https://google.com https://hcaptcha.com https://soundcloud.com https://stripe.com https://stripe.network https://stripecdn.com

The process for "https://audioplugin.deals" is the only process with a tab. All of the other processes are subframe(s) only, with no mention of which tab is using them.

With only one tab open, I intuitively know that all of these processes must be used by that one tab. But like most people, I browse using multiple tabs, and once you open multiple tabs, it becomes (as far as I can tell) impossible to determine which subframe(s) process is used by which tab. This makes it impossible to determine which tab is behaving improperly or erratically when there are issues (for example, when one of those subframe(s) processes is consuming an unreasonably large amount of memory or CPU cycles).

Recently I've had this issue (on reddit) where after I expand a video in the feed, and start scrolling, all the visuals freeze.

I know it's only the visuals, because I can still interact with the website (usually unexpand the video, or pause it) with the image still frozen and audio still playing.

I can fix it by tabbing firefox down, and then up again. While researching I found the profiler, and finally managed to capture the moment it happened.

I'm no stranger to technical stuff but it's a loooot of data to process, I did a "clean" profile recording as well where I did the same action and where it didn't freeze, and I can't really make heads or tails out of what the issue is.

The recording managed to capture the phenomenon and I only clicked twice during that period, to expand two reddit expando videos, the second one is what caused the issue when scrolling. The only thing I see is a spike in memory usage

Not sure if I can (or should) upload the profile recording here or what, but it's been bugging me a lot.

It's pretty tricky to replicate because it seems to be random when and what triggers it, even expanding the same videos doesn't replicate it. Sometimes I go days without it happening, sometimes it happens 6 times in a single session.

I've added some screenshots of various views of the profiler/stack data.

I have an Nvidia RTX 5070ti GPU, hardware acceleration is on, AMD Ryzen 7 9800X3D processor.

I think I might have enabled some rendering settings in about:config, maybe it's related to that but I don't remember exactly what.

Maybe it's due to some windows "game optimisation" or the GPU and CPU-GPU fighting?

I have no problems watching videos while playing games or anything though.

Up until maybe mid last year, I had an RX580 8gb. I was able to game on my main screen and watch videos on my second screen with no issues. Then I upgraded to a 2080 and now a 3070. When I switched to the 2080 I ran DDU. But ever since switching to NVIDIA whenever I game and watch videos, mainly twitch, the framerate on my game and twitch tanks. Sometimes it even causes a timeout or causes the video to corrupt, then I have to close and reopen the tab. From what I can see in Task Manager, the video decode just starts dying. Sometimes if I pause my game and then pause the video the frame rates will return to normal. If I'm watching something on YouTube, I'll instead get audio issues where the sound on the video will lower if the sound on the game gets louder. I've tried reinstalling Firefox, but that didn't help. I've tried messing around with my internet settings, resetting my modem, that hasn't helped either. Drivers are all up to date. My specs are:

- Gigabyte 3070 oc 8 GB - 16 gb ram - ryzen 3600 - X570 Steel Legend (non-wifi) - Windows 11 pro

I've noticed in the last few days that I'm periodically losing keyboard character input on sites following the update to the latest version - 148.0 (64-bit) I thought it might be a power issue with my WiFi keyboard and swapped out the batteries but the issue has persisted and I haven't experienced it when testing in Edge and nor have I seen it when using Excel or Notepad++ which I use regularly. Keyboard input actually froze for 4-5 seconds in inputting the last sentence. The problem is presenting on a number of sites - e.g. Reddit and YouTube. I do use the Ublock Origin extension but have been doing so for quite some time. I did report an issue with the mid screen search bar a few days ago and believe that is to be corrected in the update of 10th March. Is this also a known issue with the update?

If I am on a website that is still loading in Firefox and want to change to another URL, then Firefox does not stop loading the old page. Once I click the "X", then it loads the new URL webpage. Shouldn't it stop getting data from the old URL the instant I load a new URL?

Firefox has definitely gone downhill imho. Too many very frequent updates after browser slows down to a virtual standstill. I have seriously been looking at other browsers. What's the story?

Hello Community,

I have been experiencing significant issues with Firefox for the past couple of months. The main concern is high CPU and RAM consumption during video playback, especially on YouTube.

This issue started appearing only for the past month or two; it was never present before on the same system, and no significant hardware changes have been made.

Crucially, this problem is exclusive to Firefox. I have tested video playback on other browsers such as Google Chrome, Brave, and Microsoft Edge, and do not face any similar performance issues with them.

Your assistance in resolving this is greatly appreciated.

Thank you.

When I log into Google, my browser freezes. I can't close the browser, can't even restart the computer — and this happens every single time I try to sign into my account, making the browser essentially unusable.

I have recently begun to have hard 'hangs' while attempting to view a video on a site I'm already connected to. I've tried to overcome these hangs, but they continue to happen even after firefox has been in use for a short time. I have to restart my computer, since the hang is locking up all control input.

For the past 15-16 days, Firefox has been consuming extremely high memory.

The problem: - When Firefox first opens, it starts normally at around 300-400 MB - But after using it for about 1 hour, a single Firefox window grows to 1-2 GB of RAM - This keeps increasing the longer I use it (memory leak behavior) - Currently Firefox (41 processes) is using over 5,131 MB total memory on my system it's normal but after 1 hour a single firefox window grows to 1-2 GB of RAM

What I have tried: - The issue happens consistently every day for the past 15-16 days - Other browsers like Chrome and Chromium use much less memory in comparison

System info: - OS: Windows 11 - Firefox version: latest version 148.0.0.0

Please help me fix this memory leak issue. It is making my system very slow.

Roblox was blocked on my device and I wanted to get it unblocked and play it on Infrexa with Firefox. I already followed steps mentioned on the official webpage: https://www.infrexa.com/now-gg-roblox-login-and-play-roblox-unblocked-on-your-browser so please don't advise similar troubleshooting methods.

Now I am able to play roblox but the problem is that when I play the Roblox through "Mozilla Firefox" it shows an error "Firefox is already running but is not responding" and then becomes unresponsive when pressing refresh button, the fan gets faster and device heats up with too much hanging. But when I open the Roblox through "Chrome" it comparatively works good and asks for login details and after redirection it allows me to play Roblox Unblocked without any issue. "Roblox unblocked" here simply means a technical sense, meaning “not crashing” or “free from software or network errors and or browser malfunction".

I have been using Firefox for a long time and my passwords and user ids are saved in the browser so I want to continue using "Firefox" as default browser but I am having the issue in playing roblox unblocked and other games through Firefox browser. I think the current issue that I have started facing is especially after a recent windows update.

I also tried many other gaming platforms like Official Roblox.com, Now.gg Roblox, easyfun.gg and web.cloudmoonapp.com but all of them faced same issues on Firefox while running ok on Chrome.

I am currently running Windows 11 (25H2 Licensed version). I want to play roblox unblocked on my device using Firefox (updated). My parents have already allowed me to play Roblox and I am playing it on my own device and internet connection. Please fix the browser issue and unblock Roblox for me. Please also check my browser version against Windows 11 compatibility if possible.

If you fix this issue for me, I will be grateful to you.

is there a way to revert the changes that have been made on ver 149 regarding the scrolling? I'm trying to scroll some really long sites and when I just touch either my magic mouse or my macbook trackpad scrolling jumps to the end. Up to version 148.02 there was no problem. I've check it on 2 machines with macos sequoia and the problem is valid.
