The problem of hanging on specific web pages but not always in the same place greatly increased 11/22/2026 running Firefox 115.38ESR under Windows 7 so I suspect that it is due to some widespread update and a new esr update is needed. 115.43.1esr did not help. Sometimes it happens while loading a page, sometimes when attempting to scroll the page and sometimes when entering data into a field.

Recommend fixes for Firefox freezes.crashes on Amazon Prime Video page (Mac Sequoia 15.8.1)

Running Mac Sequoia 15.8.1 I launch Firefox, login to Amazon Prime and when I get to Amazon Prime Video page, Firefox freezes, won't respond at all, and play button shows a rotating circle (see attached). Firefox -does- play video on Youtube and other video websites. Safari on this same laptop plays Amazon Prime Video just fine. All other computers/browsers in my household utilize Firefox to play Amazon Prime Video just fine, so it's something out of whack on this MacBook pro. I have uninstalled and reinstalled Firefox several times with full reboots each time but to no avail. Please provide any other options.

My Macbook Air (M1, 2020) has be moving slowly recently. I wondered if how I'm using Firefox could be contributing. I typically have two Firefox browser windows open, with 5 or 6 tab groups each with several tabs.

In addition and more specifically, I'm wondering if closing (collapsing) a tab group means those tabs won't be contributing to my computer's CPU load. Thank you.

If my Macbook Air Activity Monitor shows that Firefox GPU Helper is using most of the memory, could that be what is slowing my Mac down?

Hi. My Macbook Air (M1, 2020) has been performing slowly in recent days. I'm not playing video games or watching videos, just mostly working on many tabs in Firefox (157.0.1). I looked in my Mac's Activity Monitor, which shows that Firefox GPU Helper is using about 5.75 GB of memory. The next few highest users say "Firefox Isolated Web Content." Could any of these be what is slowing my Mac down? I'll attach a screenshot of my Activity Monitor. I also clicked "Share Data" below. I would say that my Macbook is working at a fine speed at the moment, so perhaps the screenshot and data are not so helpful. Let me know if I can add something later in a reply, when my Mac is moving slowly, that would be helpful. Thanks.

Firefox's performance keeps getting worse. I have to clear the startup cache several times a day just to get any sort of decent performance! Reinstalling hasn't helped, and disabling add-ons hasn't provided a solution either. Has anyone else experienced this, and/or does anyone have a solution to the problem?

I started noticing that Firefox was giving me a lot of "not responding" freezes the past couple of weeks. The past couple of days I basically cannot access Firefox at all - constant, immediate freezing. I have tried uninstalling/reinstalling (multiple times), disabling hardware acceleration, running troubleshooter mode (still freezes! if it opens at all!), deleting profiles, restarting my computer, etc. I've done just about everything I can find online about this issue. Nothing has worked. I have no issues with Chrome or Edge.

Any suggestions??

I browse exclusively with Firefox on a Windows desktop. Edge is installed but unused. Even so, Firefox unpredictably starts as many as seven Edge Webview2 processes, which invariably bog the computer down. (Webview2 pops up only when I use Firefox and usually when nothing else of consequence is running; so Firefox seems the likeliest culprit.) Microsoft says that trying to uproot Webview2 will disable many apps and may end civilization. How can I prevent Firefox from invoking Webview2?

When starting Firefox after a PC startup or restart in Windows 10, Firefox will lockup and exhibit a "Not Responding" message. Windows will then show a "Close Program" or "Wait for the program to respond" choice. This happens on any of my machines, Windows 10 and 11. It's to the point of wanting to uninstall it. After it finally loads the first time it loads fine on subsequent loads.

Ever since the update to 157 I have been having issues when running firefox. Youtube is non functional on the browser. It is using a large amount of memory (consistently at 41-45% according to the task manager). Gmail takes a long time to load, in fact every page takes a long time to load if at all.

I run it in troubleshooting mode and functionality returns... I don't want to run firefox with all my extensions disabled they are there for a reason.

This update seems to be inherently unstable and is causing issues for lot's of folks.

So just to summarize, the update to 157 has not worked. It is using a disproportional amount of memory, that the previous version did not. It is causing my entire system to downgrade and run significantly slower. Pages will not load properly and I am now using a different browser as a work around.

Essentially it is a huge failure and I wish you would have tested more thoroughly. My experiences are not uncommon... You guys released a garbage upgrade to the browser that has catastrophically under performed.

I do not recollect any update in the past that functioned as poorly as this. Congratulations for completely screwing this up.

When will you guys get this working properly?
