I am not sure if you have herd this or not since the newest Firefox update everything is very slow. takes forever to get anything on Firefox especially with extensions enabled. Especially Facebook . Now i am not sure if this is Facebook's fault or if it is Firefox Iam using this version149.0 64 bit. if it is not Firefox have you hear d or seen yourselves about Facebook not loading correctly . Please if anyone knows of either problem feel free to contact me

Previously, had no problem loading YouTube videos in multiple tabs, switching between them and them playing their videos with no freezing , pausing or buffering. Since the last upgrade loading a single YouTube video causes it to freeze and continually buffer. And Firefox is spawning multile copies of itself in task manager. (One instance had 15 copies.)

Hello all,

I've been a long time Firefox user and recently (starting about 2 months ago) started seeing some irritating behavior while browsing. Firefox will at random intervals "gray out" either while interacting with specific webpage elements, or browsing specific websites. An example of this "gray out" condition is included as a screenshot. The browser will flicker between this "gray out" condition and the webpage, occasionally staying in the "gray out" state for 3-6 seconds. As you can see in the screenshot all Firefox UI elements are also missing, so this seems to be broader application issue. I've noticed this particular issue repeatedly on Amazon.com while moused over product photos.

I consider myself a power user. As for my PC, it is running Windows 10. All graphics drivers are up to date. Other apps run normally. I've never had any problem browsing/interacting with similar web content in Microsoft Edge... but I heavily prefer to use FireFox. Has anyone else encountered an issue like this?

just agreed to the new update for firefox and now my scroll bars will not work properly. they keep jumping to the far right hand side of page and when moving the scroll bar to the left so I can view the whole thing it will not stay. it jumps back to the right side.

Hello

I have a 2021 IMAC desktop OS 13.7.8 In the last few days I have updated to Firefox 150.0 since then, my computer will not sleep if Firefox is open even if I select the Apple menu---sleep to manually make it sleep, it goes dark and comes back awake within 5-10 seconds. I CANNOT get it to sleep with Firefox open. If I close FIrefox, then I can get it to sleep. ANy windows that I keep open are windows I have had open for weeks and this did not affect the IMAC;s ability to sleep in the previous version of FIrefox. The only thing that has changed is FIrefox so I am telling you there is a problem...PLEASE fix it asap.

YES.....I have , as suggested in help sources.....done these..... 1)Settings > Privacy & Security > Autoplay and set it to "Block Audio and Video" 2)about:config in the address bar, search for media.video-wakelock, and set it to false

im playing farmville 2 in zynga games online but it plays very slow ans keeps freezing. ive done what was recommened but there is no change to the game, i was wondering if you could help by telling me if there is anything i need to do in the browser to get this game working better

Good morning. I don't know how to describe it well much less grab a screenshot as it happens so quickly. Occasionally when I open Firefox which is always full screen a blank/black smaller browser window opens/appears for a second or so and then the browser opens as normal. It does not happen every single time. It's like on the way to opening the browser takes a step and then activates. The browser is up to date and seems to be working fine. I am attempting to catch a screenshot but as I said it is so quick. I don't know how to describe it any better. If anyone can help I would certainly appreciate it. I have run multiple antivirus, malware and spyware programs and found no issues.

Youtube playback causes Firefox to freeze up. Just the tab that is playing, not the entire browser. I have reinstalled firefox, used recommended settings and I have no addons or extensions. Other browsers work fine and there is nothing wrong with my computer. It is only firefox. This has been happening for about a month now.

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.

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.

When watching twitch and I open another tab, the new tab is very slow to open a web page and sometimes wont open at all just keeps scrolling. Any suggestions how to solve this problem?? I tried with Opera and it doesnt have that problem?? Dont want to give up on Firefox as I like it the most. Any help much appreciated.

everytime I try to get to my sites its very slow and it says mozilla firefox not responding If I wait for a while it will finally allow me to get to my site but it takes a long time

I recently (within the last month) gotten an update in windows 11 and all of a sudden firefox slows way down and eventually stops doing anything...Any ideas what I can do to get firefox to actually work all the time??? I am using firefox 149.0 and it says it is up to date...

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.

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.
