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

Firefox (152.0.4, 64-Bit) security settings – whether intended or not – are blocking work on the Internet. For example, loading Amazon takes forever until it’s unreachable, and further browsing (scrolling often not possible). The same with Edge works without any problems. What do I need to do to work quickly without constant blocks? Is there a zero setting? With simple security settings? The issue seems related to https to http as well. Also, opening a private new window once works, but a second window is blocked.

Since the last upgrade Firefox is running very slowly. Many sites that I use daily either take so long to open or don't open at all. I have to open MS EDGE which opens up these sites within microseconds.

I prefer using Mozilla, but unfortunately looks like I may have to move as Firefox is now almost useless for me.

Can anyone suggest anything I could try.

thanks

Chrome user returning to Firefox here; I'm experiencing an issue where most pages would take at least 4 to 6 seconds to load, especially for heavy media sites like YouTube which could take 6 seconds for it to be barely usable, and 10 or 13 seconds for it to finish loading. My internet speed is 1gb at most and 800 Mbps at the least.

It loads sites like Reddit pretty fast, like 3-5 seconds interestingly. It's largely YouTube and other sites where the pages load infuriatingly slowly, and Chrome Mask did not helped with this.

Here are the things I did: Refreshed Firefox, started in Troubleshoot mode, installed Chrome Mask for YouTube (Did not work), disabled DNS, closed all foreground apps except Firefox, used a different profile and enabled/disabled hardware acceleration.

Specs: CPU: i5-3570k GPU: GTX 1070 Ti RAM: 16gb DDR3 OS: Windows 10 Hard Drive type: SSD

Final notes, it says I use Microsoft Defender Antivirus but I am actually using Malwarebytes. I also use uBlock Origin which is the entire reason why I permanently switched from Chrome to Firefox.

Firefox ver 152.01 64 bit on win 11 recently very slow to load tabs, and if on you tube very slow to show pictures of the video's, also in Task manager with two tabs open shows 1,154 MB and in the App's section show 14 Firefox open. If I use Edge they open very fast, and & have now stopped using Firefox for this reason. I have been using Firefox for many years without any problems but now not really usable any more, unless this can be fixed. John

Firefox stops loading pages. I try to browse a webpage and it just keeps loading, but nothing happens (black screen). I open chrome, request the same webpage, it loads immediately. In Firefox, it keeps loading. Sometimes it loads it after 1-2 minutes. Sometimes not. Problem is fixed after restarting firefox, but comes back again after some time.

Hi hi, I just did a complete reset to factory settings of my laptop (MSI), and a wipe of my hard drives too. After reinstalling Firefox (literally the first thing I did after setting up windows), it runs more slowly than before the reset (even for a basic search on Google/Duckduckgo). I am also unable to load any pages under the domain discussions.unity.com : the page loads forever, it's impossible to click on anything (even the hovering styles don't work), and I get a banner at the top of the screen that says "This page is slowing down Firefox. To speed up your browser, stop this page.". Also the memory usage for this page skyrockets (gone up to 4000MB??). I've disabled the 2 extensions I have (Dark Reader and Adblock Plus), restarted Firefox, restarted the computer, cleared the cache, even turned off the mozilla syncing, nothing worked. Any idea on what could be happening here? It's the first time in using Firefox for over 15 years that I've seen this happened.

Thank you for your time and attention <3

Ever since the last update or two when I click on links to open websites, it renders a white screen and I see waiting at the bottom. It takes forever for websites to open. I have toggled acceleration on and off, disabled Windows 11 Efficiency Mode and nothing is working. I am a web developer and I really need websites to open. They open quickly in Chrome but not Firefox after the update and I may need to start using Chrome.

Although I am using the latest firefox update and have cleared all firefox data and cookies it can take up to 30 minutes for facebook and instagram to load. When I switch to Google Chrome both facebook and instagram load instantly. What might be causing this? Thank you.

I use several browsers and when it comes to functionality I consider FFox to be the best however with 1 major drawback - it's speed / lag issues which is why I stopped using it as my primary browser and only as secondary one

I can have 2 different Chromium based browsers open simultaneously and while this impacts the performance somewhat if I open Firefox and another browser responsiveness grinds to a halt (sometimes even crashes)

Even just starting Firefox by itself takes 5x as long as other browsers

So I'm wondering is Firefox just more resource intensive or is there something wrong with my setup?

The main difference between my Firefox install and my other browsers is the number of Bookmarks (10000s) due to me having it installed for much longer so is it possible for a large number of Bookmarks to slow the browser down even when not open ?

Other possible causes I read elsewhere are 'Cookies and site data' (currently around 50mb)

I clear the 'Temporary cached files' & 'Browsing history' on regular basis so they shouldn't be an issue

The add-ons I have installed are NoScript , Ublock Origin & Firefox Color

In regards to troubleshooting is it possible to install a 2nd install on the same system simultaneously without overwriting the current one ?

Thanks

I have been user of Firefox for many years now, always setting up as default browser and in early times even uninstalling Edge, but within the last year i see more and more websites getting sluggish in firefox, Sites that dont fihish to load, blank pages, opening links taking long time. Facebook, ebay, amazon and many online stores are getting worse by the day

At the same time i open Edge and it fly, no sluggish nor blank pages, no delays

I dont like edge, i am not interested in using it

Is there a bunch of settings i can tweak to make Firefox more fluid in those websites?

Thank you Frank
