Firefox Community Forum

About a week ago, my Firefox browser started being extremely slow to load. It loaded the shortcuts but the page full of news things to click on never loaded. Instead, the rectangles where they would go were just illuminated from left to right with a gray sweep light to dark over and over. I left it going and hours later it was still doing it. I clicked on some of the shortcuts and some came up and others did not, at least during the time I was willing to wait. I went to Google Chrome and it was slower than usual but eventually I was able to get to my email, ebay, etc. I spent hours on the phone with Xfinity/Comcast and they ran tests and said everything was ok. I checked and found that I have the latest version of Firefox. Is it possible that an update caused this? If not, what is going on?

Apologies in advance if I use terminology incorrectly.

I've had this strange but intermittent issue for a while (through multiple Firefox versions) where pages will take a long time to load. I haven't timed loads exactly but I can confidently say it's a minimum of 10 seconds. The problem with diagnosing this issue is it's very intermittent; I can go hours or on a rare occassion days without it happening (I think, maybe I've just not registered some of the times it's happened). I have yet to try disabling all addons because of this.

Random quirks about the issue:

• It only happens on navigation to a new domain (or to a domain from a new tab). Once a domain has loaded, I don't have an issue on said domain for a while.
• It isn't tab specific. I can open a new tab in the same window and they will both take the same amount of time to load, often finishing at the exact same time.
• While waiting for a page to load, I can open a Private Browsing window, paste the URL, and the page will load immediately without issue in the Private Browsing window. This does not affect the page being loaded in the main window.
• I believe it has occurred immediately after a system restart, thus I don't believe it is related to long-running sessions.

The addons I have that don't also run in Private Browsing are:

• Augmented Steam
• BetterTTV
• Enhancer for Youtube (I can't find the addon store link?)
• Firefox Multi-Account Containers
• PocketTube
• Return YouTube Dislike
• SponsorBlock
• The Camelizer
• Youtube High Definition

since the uptate to version 144.0.2 I have two problems. the first one is async streaming on platforms eg. youtube or netflix. The videos take a very long time to load. Even if a video has already preloaded and I skip to that area, the video takes an extremely long time to load again. The 2nd problem i have in livestreams eg. live-TV or twitch. The loading time is very long. It is so long that many livestreams are doesn't even able to start. So, it is no longer possible for me to watch livestreams on Firefox. what i've done to fix it: - I deactivated all Add-on's and deleted all browser Data - I made a new profile and deleted the old ones - I reinstalled Firefox

Nothing worked. so pls can you help me that I can use Firefox normally as usual? (sorry for my bad english, I'm from Germany)

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.

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/

Since the last Firefox update, normally used web pages load very slowly or time out. When clicking on a bookmark the page loads very slow so I stop the page from loading and hit refresh and it loads almost instantly like it normally used to do. Any fixes available? Thank you, Dan.

I've had Firefox as my main browser on my Macbooks for over 20 years. It is becoming increasingly frustrating working on something and realizing the computer is slowing down when loading websites, only to realize there is yet another update that requires the restarting of the browser. This is especially annoying when on a Zoom meeting for instance, and trying to open a website.

I usually have 80+ tabs open across 4-5 windows. When restarting the browser, I now have to open each tab to log into whatever site I was in.

Why does Firefox have to do SOOOOOOO many frequent updates that require restarting the browser, and why does it have to slow down your computer when there is an update?

It's like you have no choice but to update it. Would it be possible to NOT slow down your computer, but give some kind of notification, say by email, when there is an important update?

SUPER FRUSTRATING!!!!!!!!!!!!!!!

Slow website loading (30+ seconds) on some websites (the same ones) for over a week now. Have tried MANY things. No issues with MS Edge loading the same sites. Using Windows 10. Data copied. Help please.

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.

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

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"

My network is pretty fast -

• Download Speed - 76.30 mbps
• Upload Speed - 113.13 mbps
• Idle Latency - 61 ms
• Download Latency - 59 ms
• Upload Latency - 18 ms

Even though this is a pretty fast network connection, my websites on firefox take a long time to load, for example youtube takes like 2 seconds to load, and sometimes some elements of the website do not even load. This is a very annoying problem which I would like a solution for.

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?

Going to ANY website, it takes "forever" to load, but after loading normal speed is experienced. One way to get a website to initially load more quickly is to click the "X" which the spinner is going endlessly, then refresh the page, whereupon it will usually load instantly.

The problem is experienced with any and every website. This problem does not occur with Chrome or Edge:

Windows 11, Firefox 142.0.1 64 bit.
