I'm experiencing an issue with the latest Firefox update. If I refresh a link/page the browser "spins out" in a rapid endless refresh cycle. In some cases, I receive an error message, "too many requests," and in other cases, the browser "locks up" and quits responding at all.

Is this a known issue?

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

Kubuntu 24.04 with various Firefox iterations including 149.0.2. It happens on stand alone, snap and flatpak versions. I do not know what triggers this problem. As far as can tell it only occurs on Wayland and not on 'X'. .... After using Firefox normally for a while I first notice the problem when I can't click into the separate search box on the toolbar, then I find I can't drag the tabs around as per usual. Then, if I click on a toolbar icon it does not respond. In summary, the toolbar becomes inoperative. I do have 9 pinned tabs but I can often have many more standard tabs up before I ever notice the problem and, today, when it occurred I only had 3 additional tabs up. So, I can't tie the problem to the number of tabs.

After the version 149, a very strange issue happens to me with Firefox. When I try to log in to some services (Google account, WhatsApp, Mozilla account) the browser freezes. That does not happen if I turn the hardware acceleration off so I essentially thought there is some issue with my graphics drivers which I then updated (Nvidia 580.142 drivers for Geforce GTX 960). But what is very strange is that the issue isn't present when I use Firefox in private mode! That means: Normal mode, HW acceleration on -- freezing Normal mode, HW acceleration off -- not freezing Private mode, HW acceleration on -- not freezing I switched to the ESR version now which works fine too. Still, I am curious about what is going on and I would like to find a solution. My system is fully updated Arch Linux. I cannot share my data since I can't log in to my Mozilla account. Thanks in advance!

Have used Firefox for years, always do current updates. Still using Win10. After browsing for a few minutes, hard drive activity increases and the mouse and keyboard become unresponsive, returning very briefly for a second or two, before once again being unresponsive. After 10 min. or so, system returns to normal. This only happens while using Firefox. MS Edge, with all the same extensions, has no problem. Have searched many times, but no useful help is found. Have already un-checked hardware acceleration, and cleared caches, Am ready to give up and switch to Edge. Any help?

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

Is anyone looking into this? I found an article that told me to remove some cash files and it seemed to fix the issue but it continues to reoccur. Some apps such as MS360 Outlook seem to trigger it, but if it was truly just a corrupt cache issue then cleaning the cash/profile once should have fixed the issue. Instead its become a constant pain in the *** and I'm tempted to find another browser. Seems very recent as well as I've never had issues with firefox before.

Ubuntu 24 Mozilla Firefox 151.0.3

Lately I can not click all of my browser tabs, only some of them unless I do not have the browser maximized on the screen. If I make is smaller then I can click all of the tabs. Since the recent Firefox update I can't find a hardware acceleration setting to toggle off to see if it helps.

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.

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.

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.)

I've just upgraded to V149 and, when using NordVPN, Firefox is now taking at least 30secs to startup. If NordVPN is off startup is instant. Prior to V149, Firefox startup was instant, both with and without NordVPN.

I get REAL tired by the amount of resources Firefox eats up with each open window. For whatever reason, having multiple windows open prevents Facebook from loading. I'll get 1 story and a "shorts" bar but THAT'S IT. Even clicking the story to rate or comment does nothing. If I start to delete windows; it will decrease the memory usage and then it will open.

However, I DO NOT WANT TO CLOSE MY WINDOWS IN ORDER TO OPEN FACEBOOK! Firefox should not be eating up that many resources. The open windows are of text and/or picture archives. There is no sound or video playing in the multiple windows open. My system literally has 128 gigs of ram memory so it seems very odd to me that Firefox is using between 11-13% with nothing running in the 15 windows I have open.

1. There used to be a choice in settings for Firefix mouse control to be optional. It is no longer available and apparently FF has created default mouse behavior.

The mouse behavior has become errant in a variety of ways. It interferes with everything online and started doing the same on the desktop.

The wheel is configured for three lines at a time on desktop. I do not want the mouse wheel to be doing anything else. I want either or both mouse buttons to open menus and function normally with links, copy and paste.

When looking in about:config the extensive number of configured mouse defaults is shocking. it is impossible to determine how to disable or delete any of them.

It has become impossible to scroll with the wheel and the scrollbar because the mouse jumps all over the page as if possessed.

It is impossible to scroll 3 lines at a time with the wheel, instead the mouse goes up and down and jumps to the top. Changing the number of scrolling lines on Desktop and in about: config so they are both 3 did not solve the problem. Tried changing both to 5 . . . no joy.

Expandable menus no longer open on some websites.

It has also become impossible to us the scrollbar effectively, instead the same behavior manifests as it does with the wheel - the mouse is jerky, going up and down and jumping to the top of the page, unpredictably.

Either way the mouse gets stuck moving up and down. After having successfully scrolled past where it was previously it returns, repeatedly, to the same previous lines each time I try to scroll further - in an endless loop.

If the mouse does functional, briefly, then half way down the page it starts misbehaving again. I already replaced the mouse several months back when the problem started, however, it was not constant. Then it started again with the new (usb) mouse. (Yes, I've cleaned it. No it is not worn out yet.)

2. Via a search I did find a list of adjustments to make in about:config while learning unexpected mouse behavior had become a common problem. I made at least 20 adjustments, and amazingly, there was no longer a problem! Smooth scrolling, no problems. However, after using the browser, closing and opening it numerous times, the errant behavior returned.

3. If there is no way to completely turn off FF mouse control, or use about:config to disable it entirely, then what is the last FF version that allowed saying "no" to what used to be optional mouse control, so it is possible to change back to it? If there is no other way to solve the problem, that should do it.

Any suggestions or solutions appreciated.

16 GB memory, 500 GB SSD. (chose to not install Windows 11 version 23 onward - so in the 22 gray zone that is both a windows 10 install and a windows 11 install - this is the windows 11 install).

My mouse (wheel) only works on the portion of the page that is currently visible; it will not scroll down the rest of the page. This problem began after 151.0.1 update just a few days ago. It works correctly in other applications such as word or excel. It also works correctly with other browsers, so it is definitely something in Firefox. Any ideas?

I've done recent updates (May 2026) and after having 3 updates in recent months, I still have difficulties with my video programs (both Zoom and "One-click) slowing down during my work which is 100% virtual. How can I revert to an earlier version where this was resolved, please!!??
