Firefox Community Forum

I use nyt.com to assess my account with Firefox. lately, it has been very slow to load and when i click on an article, it is very slow to load.

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.

Mozilla firefox browser is SOOOOOO SLOOWOWOWWWWW loading and working. Takes literally minutes after clicking open the browser for it to even finally eventually load the tabs - pages. Then it often lags, slows way down. Making it useless for people who value our time and life. 133.03 version. says its current up to date.

Please fix it so it works correctly efficiently.

Hi,

I know that Google's doing everything to push everyone to use their spy software Chrome, but now youtube is really slow (15 seconds to stop a video when I click on the video, same to start it, 10 seconds to open a new dongle for youtube, and roughly 5 seconds waiting in others services).

Also, some others website work very badly or sometime not working at all with Firefox, why ? I have Ublock on Firefox too

I came back to Firefox for my privacy but if 35% of websites not work with it, not great. Have you an idea how to solve this problem ?

Thank you,

Matt

I have to resort to using Chrome (yuck) when using Fedex.com. Please fix issues with Firefox and Fedex.com (very, very slow loading) thank you

I know Firefox is slow when opening Facebook. It's busy blocking all their crap. But recently it's been super slow and non-connective to many sites I visit often. I've Ookla checked my connectivity and their excellent. Logging into sites I've visited before is now taking a long time some having to be resent. IE: www.clevelandclinic.org, local government sites etc.

For days I have been seeing Firefox be very slow to load a page (as in minutes) or stop working entirely. At the same time Chrome works fine. Mac Mail has become intermittent as well. I have uninstalled Norton products and changed Network proxy settings many times. Nothing helps. I have created new profiles. I switch between profiles. I have hacked into my WiFi router. Nothing, nothing helps. Safari hangs up too. Firefox on my android phone continues to work properly when using my Wifi router -the same router my Mac Studio connects to the internet with. I can access my third party mail service via Firefox on my android phone. Both FireTV devices work. I am at my wit's end. At this point I have shifted all of my work over to Chrome.

I have cleared caches. I have gotten rid of all cookies. I have restarted Firefox and rebooted my computer countless times.

Mac OS Sequoia 15.5 Firefox 138.04

Hello! After a clean install of Windows 11 24h2 Pro, Mozilla Firefox is unusable. It takes about 2 minutes to load a page which is abnormal. I remember I had the same issue when I first installed Windows 11 23H2 Pro and that was resolved somehow but it was 2 or 3 years ago and I've no idea what the solution was back then. I've tried some basic stuff including Test suggestion which of course didn't resolve anything as almost all of them are referring to cleaning cache, reinstall Firefox etc and it literally has nothing to do with my situation. Any solutions?

The server at iso.scanfor.scanfor.be is taking too long to respond. iso.scanfor.scanfor.be is an unsecure (http) INTRANET site not publicly acessible (local server). At same time other browsers are perfectly able to access the site! So there is NO connection issue... This problem happens mostly in the morning, and solves itself during the course of the day  :)

Anyone any idea where to look for an issue???

A business website has a page that allows me to see items scanned to their server for the last 90 days. The server hosting this page takes more than 1 minute to begin loading to the browser - the back and forth symbol in the browser.

I timed this event today, and Firefox times out after 1 minute. My work around is to use Chrome with the same webpage and it took more than 4 minutes before images started to arrive.

It would be handy to have the timeout adjustable in the settings tab of Firefox. If I choose to sit on what I know is a very slow website for 5 minutes so be it.

Let me know what adjustments I can make - 400mb internet, 5ghz hard wired to the router. This is the slowest site we ever access.

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! ;)

Why does it take up to an hour for apps like facebook or youtube and others to open after firefox updates. What can I do to fix this? I'm very tempted to delete firefox altogether and will if this issue can't be solved.

For the last few months I've been getting slow responses with online applications. When I switch to chrome, it all runs at a normal pace. Specifically with " The Customer Factor"
