Firefox Community Forum

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

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 have tried several online suggestions to speed up page load on my Firefox browser. None have improved my situation. I can start a web page load on Firefox while simultaneously working from another browser. The other browsers load and I am able to complete my business before Firefox even loads. I am quite frustrated by this as I have used Firefox for as long as I can remember.

I am using Windows 11

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???

I use Yahoo as my homepage and access it through Mozilla. Normally it loads in mere seconds. Last night and today it is taking extremely long to load and in some cases it has timed out. When it does load, all the pictures and other features are not included and either don't load or load much later.

I tried to load Yahoo from MIcrosoft Edge and it loaded perfectly. I am assuming there is an issue with Mozilla?

Thanks for looking into this matter and letting me know.

Trying to browse ebay using Firefox. The pages have become really slow when loading.When scrolling down the page is blank then slowly populates as I scroll down the page. I've just tried microsoft edge and there is no problem.

Hello, recently I have done in-place upgrade of windows 10 to 11. From that time loading of some pages in Firefox was very slow. For example www.google.com was loaded for about 90seconds. But next loading of the same page before Firefox restart was fast. So I had suspicion to Dns. But when I disabled DoH (Dns over HTTPs) nothing changed. What helped was to set the problematic page to DoH exceptions. So seems, that disabling of DoH is not really disabling, minimally on Windows 11. For sure during troubleshooting I tried it with disabled extensions, new profile, ... But nothing worked. Is there any other way how to disable DoH completely in Firefox? Setting network.trr.mode checked and was set to 5, which should be disabling.

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"

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.

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.

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! ;)

Ok, this is a weird one.

I can't load https://duckduckgo.com. It breaks search in a new tab, but I also can't visit it directly from the url. The tab simply does not load.

I've cleared cache, cookies, and extensions. I've refreshed Firefox more than once.

I can visit https://html.duckduckgo.com. I can visit https://lite.duckduckgo.com.

However! In a private window, I can visit https://duckduckgo.com It still breaks in a secondary normal window.

No other site appears to be broken.

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/

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 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.
