Firefox Community Forum

like the title says, usually at least once a day firefox will just stop loading web pages entirely. more specifically, it gets stuck loading any page infinitely. occasionally if i wait long enough things will start loading again, but usually that time never comes and i have to restart the browser. i'm kind of a tab hoarder so restarting the browser can be annoying in itself, since i have to wait for the browser to load. i'm not really sure how to troubleshoot this with extensions and the like since i haven't noticed any trend in when the problem occurs. weirdly enough, it happened while i was typing this and while every other website fails to load, the mozilla support site is consistently fine. any ideas or suggestions would be greatly appreciated.

everytime I do an update it takes forever for the tabs to load and open....if I did the vpn will my passwords also be saved and top sites be saved as I can not do fire fox top sites so have a different top site

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

Hello Mozilla Support Team,

I’ve noticed that my website, https://firehousesubs-menue.com/, is loading significantly slower on Firefox compared to other browsers like Chrome and Edge. It takes noticeably more time to fully render pages.

Could you please guide me on how to identify what might be causing this issue in Firefox specifically? Are there any known compatibility or performance issues I should be aware of, or tools within Firefox to help me debug the problem?

Thanks in advance for your support!

Muy problem is ony desktop.. A few days ago I started having the problem that when I click on a link, a new tab opens but it does not load any content. The little dots on the tab go back and forth but nothing loads. My home page always opens and I can open articles on that page, but new links do not open. I restarted the computer and it seemed that the problem had corrected, and I was able to open a couple of links but then nothing more would open.

Bonjour, Depuis 1 semaine à 10 jours, il m'est impossible de naviguer avec Firefox. La lenteur est exécrable. J'ai dû mettre 1 heure à pouvoir afficher cette page, incluant tout ce que vous faites pour décourager les gens de vous écrire. Votre dernière MAJ doit être ratée. Avec Edge, je n'ai pas ce problème. La navigation est fluide. Je vais aussi tester Chrome. Cordialement,

Hi all! Happy Firefox user for over 20 years here. Recently I've had to switch to Chrome for one of my use cases, Google Cloud Monitoring dashboards. They're evidently JS- and data-heavy, and they're often unusably slow in Firefox. I often see delays of 10s or seconds when clicking any button or link, rendering data, or doing anything else. They also seem to get slower the longer their tab is open in the browser. They're way more usable in Chrome; maybe not perfect, but drastically better.

Any thoughts?

I've used about:performance to take a profile on https://profiler.firefox.com/, and uploaded it to share.firefox.dev , and I know it claims to sanitize personal info, but I'm still a bit leery of posting the link publicly. Happy to share it with a Mozilla employee if that would help.

As the Subject line says, Firefox will act like it's working normally for a little bit but shortly after using it websites stop loading and no new websites can be accessed. Usually after about 10 minutes. Closing and reopening Firefox restarts the cycle. Works for a bit, then stops. Other browsers like Microsoft Edge and Google Chrome work fine.

I've checked my Firewall, deleted and re-added Firefox, made sure it had both Public and Private Network access. Also tried using Firefox in Troubleshoot mode and tried resetting Firefox. Same behavior, made no difference.

I don't see any error messages when this happens. Tabs just spin and load indefinitely with nothing ever appearing in the window. Anyone have any ideas?

I am having issues with sites, where I can access main page but then when i try to move onto another area of the site I just get spinning. I have had this on different sites, from Amazon, Disney. I have tried clearing cache, i have made sure Firefox up to date but can be very sporadic.

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?

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.

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.
