Firefox Community Forum

Firefox runs some sites slows on one of my Windows 10 computers.

I'm running Firefox on 4 Windows PCs and 3 of the 4 work just fine using the same synced profile.

Fidelity.com and Amazon.com are 2 of the sites that are very slow to load. They will eventually load, but clicking on any links causes another slow load.

The same web sites are fast when I use MS Edge.

Troubleshooting steps I've taken (none of which have worked):

• Refreshed Firefox
• Created a new profile
• Uninstalled Firefox leaving my old profile
• Completely uninstalled Firefox and deleted my profile

Any thoughts on troubleshooting steps to take?

Hi to all.

Any suggestion?

Thanks and regards

Hi! I’ve noticed that the site with Slider Revolution installed opens quite slowly in my browser. Do you have any idea what this might be related to? In other browsers, it seems to load just fine. Thanks in advance for your help! Link: https://kasiinod-ee.ee/

I am having a lot of difficulty opening websites ( NYtimes, Washington Post) they takes minutes to open. Sometimes minutes more to open article. ATT says line service is fine. NYT says it service is fine and it works on EDGE Any thoughts?

updated to latest firefox 136.0.1 today and several web pages will not load on first attempt. yahoo.com, google along others indicate that page is preventing this site from loading. I have not encountered any issue with Chrome. Have not encountered this issue with firefox previously but very frustrated user. I any attempted to start firefox in debug mode without any extensions or tools and firefox still encountered the same issue. Any recommendation would be appreciated.

Good day. I'm thinking of deleting Firefox. It's simply impossible to use it on some sites. For example, I can't write a comment on YouTube because the browser freezes. Page scrolling and controls also freeze. I turned off browser extensions, but it doesn't help. I have 48GB of DDR5 memory and one of the best processors available today...

My browser worked fine until a few weeks ago. It then slowed considerably in serving pages. Instead of a few seconds, it would take 30 seconds. It has done this consistently since then. I don't recall installing new extensions. My other browsers work normally at normal page speed. The Windows OS seems to work fine as well.

Can anyone think what might be causing this & how to fix it?

When I try to download anything Firefox Caps my download speed at 10MB/s Other browsers don't. I tried, Edge, Chrome, Etc... they all give me access to my full Gigabit speed. I've attached 2 screenshots with a SpeedTest comparison.

Firefox: 90mbps Edge: 630mbps

Am not being hyperbole but I swear to God I love Firefox more than anything. Okay, let's get to the main topic. I have a problem with Firefox on my pc, whenever I open Firefox one of my CPU thread is dying and its causes brutally lags. I know I have a potato rig but at least fix this browser as smooth as before. After I having a problem with dying threads whenever I open a tab and going to a website I desire it took so long isgt. I thought my pc was the problem one and I think "Ah I should upgrade my pc, but I still in debt" and it turns out the Firefox was the main problem.

Please Firefox fix this for me, don't suffer me more. I'm migrating to Chrome for a while cuz the Chrome didn't kill my CPU thread (I tested it for almost 2 weeks).

I attached you images from time to time, hope you could understand it! ;)

Windows11，firefox版本149.0，增强型跟踪保护设置为标准，基于 HTTPS 的 DNS”启用策略为默认保护，扩展全关。在我打开www.douyin.com的标签页时，通常要加载5秒钟甚至10秒钟，视频才会播放（如图）。作为对比，我在edge浏览器上登陆了同一个抖音账号，打开同样的书签页面，edge并未出现明显加载画面，在chrome上打开未登陆的抖音标签页也未出现明显加载画面。这个情况也许是从近期firefox自动更新后出现的？请问如何解决

I'm having trouble signing into to some online news sites especially videos. The screen shows activity without actually loading a video or website site. I can't connect, it just keeps spinning.

WTF IS WRONG WITH MOZILLA?

So, I'm browsing a website (shopping), going back and forth through its menus/categories and also opening tabs in the background, then every few minutes the whole browser goes blank/grey and the tabs "dead"... they're not closed just blank and I cannot go backwards or refresh... I have to close the tab and reopen it from history...

Did I explain this clearly? I've been putting up with this for 2 weeks, but now I've had it... I'm staring at a blank tab I cannot revive - refresh or back button don't work, AND another tab which is displaying a "Loading wheel" and also frozen...

I've only recently started using Firefox (I use 2 other browsers above this - each with a distinct purpose, and also started giving-in to Edge as a 4th, despite being opposed to everything Microsoft for 20y).

If I continue to experience this in the next couple of weeks, bye bye Mozilla...

Hi everyone,

I am facing a strange issue with web browsers on my HP system after a recent Windows update. No matter which browser I use Chrome, Firefox, or even Edge webpages take much longer to load than usual. The connection itself is stable because downloads and streaming work without any problem, but normal browsing feels unusually slow.

I have already cleared the cache, disabled extensions, reset the DNS settings, and restarted the router. The issue still appears across all browsers. This started immediately after the last Windows update, so I am unsure whether this is a compatibility issue, a driver problem, or something in the network configuration.

If anyone has seen this behavior before or knows what additional steps I should check, I would really appreciate your guidance.

Thank you.
