Hi, I’m facing an issue with Mozilla Firefox where some websites load very slowly, and sometimes pages don’t open completely or show loading forever.

I’ve already tried restarting the browser and checking my internet connection, but the problem still happens randomly. Other browsers seem to work fine on the same network.

Can anyone guide me on what could be causing this issue? Are there any Firefox settings, cache options, or add-ons I should check to fix this problem?

Thanks in advance.

Recently I’ve had a few Firefox problems on my W11 desktop. Sometimes when I try to load a website, nothing appears until several seconds (30 or more) have passed. During that time, the bottom of the screen shows the message Transferring data. Then, after that long wait, very often only a top piece (1/3 to ½) of the page appears. If I wait long enough (a minute or two), the rest of the page appears. Another problem is illustrated in the two images. When I go to AARP, I get the first image. T then press the Reload button and the second image appears. This problem is fairly recent. Previously, the first image always loaded with not problem. Any ideas of what’s happening and, even more importantly, how it can be fixed? Thanks.

I’m noticing a strange performance issue with my website: Wildiferemovalpro

On Chrome and Safari, it loads perfectly fine. However, when I try to open it in Firefox, the loading spinner just keeps going, and the "Time to Interactive" feels significantly longer.

I’ve already tried:

Clearing my Firefox cache.

Disabling my extensions.

Checking on different machines.

Is anyone else seeing this? I suspect it might be a script or a specific CSS rendering issue unique to the Gecko engine. Would love it if someone could take a quick look and let me know if they see any red flags in the console.

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???

For the past few days, DDG search has been slow. I'm using Firefox version 146.0.1 on Windows 11. Disabling extensions didn't help, but clearing the cache had an effect: The first search after clearing cache is fast (about 1 second), but subsequent searches are slow (about 15 seconds). I was able to repeat this sequence several times. I also cleared cookies, but that didn't seem to have any effect. DDG Search works fine in a Private window. I'm stumped!

Hi, I've noticed that web pages load slower recently. As all of the recent updates seem to be about adding AI features to the browser, I can only assume that this is the problem. I have disabled the .ml. settings and saw an improvement in performance, but performance is still degrading over time as new updates release, so I'm guessing that I missed something in the settings.

I'm also concerned about privacy. As these AI features make use of tools that cannot always be run completely locally, it increases vulnerability to provide very little value, if any at all. I would argue that it makes the browser worse rather than better, so that's not worth any level of risk to me.

If these features continue to be expanded then I will look for an alternative browser. I know that it is tough to find browsers which aren't Chromium-based these days, but it's not impossible. Firefox is not the only choice.

About a third of the time when I go to a new site I have to "reload tab" once or twice. Sometimes it will open the site and then stall and I have to "refresh". You keep upgrading so I assume my software is up to date.

Hi,

Any suggestions for Firefox being really slow? Slow loading webpages. This has been going on for about a month. Maybe longer. I have the same issue in Troubleshoooting mode. Firefox is updated. Cleared cache and cookies. Rebooted. On a Mac laptop.

I keep using Safari and I'm about to more over permanently.

Thanks!

My fire fox which I have used for years is loading page very slowly and then freezes some times but just tried my Edge Browser and its as fast as my fire fox years ago. what can I do to speed it up

My "Email Link" suddenly quit working about a week ago. I use this every day and often. I have made no changes nor am aware of any other. Online I see many people have this problem and in different browsers. Suggestions I see are irrelevant or beyond my understanding even though I am an experienced user, but no pocket protectors. Also since I got Windows 11/new computer over a month ago, some pages take forever to load. I see all kinds of computer handshakes, looking up, google this-that and so on in the bottom left corner above the Windows icon. Have never seen that stuff before. Is this a clue re: my "Email Link" problem?

Help would be much appreciated.

I have this new issue, that Firefox needs like 3-4 seconds, before loading a page. It stays blank until then. Why has the Performance decreased so much?

Reinstall didnt help

Greetings, I have a problem with Firefox taking too long to load websites after login, while Edge loads websites immediately. It happens every time I lift the laptop lid and login. I have restarted Windows 11 and tested the load times of Firefox and Edge a while ago by going to Google. Edge loaded Google after 5 seconds, while Firefox 3 minutes and 25 seconds. That's long. Sometimes Firefox loads a webpage 10 minutes after login.

What could be the issue here and how do I fix it? I have the following extensions and I'm sure that they do not hinder Firefox.

Hello,

I’m reaching out because I’ve been experiencing persistent loading delays on Firefox across all websites. Pages eventually load, but it consistently takes longer than it should or don't load at all, can't even log in on some sites such as Twitch. At first, I thought the issue was only on YouTube, but I’ve confirmed it affects all websites.

I’ve already gone through extensive troubleshooting steps, including: Clearing cookies and cache Changing DNS providers (tried both Cloudflare and Google DNS) Using the Firefox Refresh option Fully reinstalling Firefox Scanning my system for malware (none detected) Verifying that no extensions or add-ons are installed Confirming my internet connection and speed are stable Testing the same sites in Chrome, where everything loads smoothly Despite all of this, the problem persists only in Firefox. Thank you in advance for your support!

Since the 145.0.2 update web pages are loading very sloooooooow. Also, images are loading very slowly, if they load at all. At the start pages would not load at all then about a week they started loading but very slow as mentioned. Any ideas/help will be very much appreciated. I am using Windows 11.
