I use Firefox 134.0.2 (64-bit) on Ubuntu 24.04.

Some (not all) web sites show up only after a delay of exactly 30 seconds. The attached screenshot shows that this delay is due to DNS resolution. This behavior is reproducible by simply closing Firefox, opening it again and entering the same web site once more. Once this initial delay of 30 seconds for DNS resolving has passed the web site can be browsed normally.

Using Google Chrome, Opera or even the Tor Browser on the same system works without any significant delay. Also a DNS lookup from the console returns data almost immediately.

As the delay is always exactly 30 seconds this looks like some DNS resolver timeout only showing up when using Firefox.

Neither starting Firefox in Troubleshoot Mode nor (as often suggested) disabling IPV6 for DNS by setting network.dns.disableIPv6 to true did help.

Any idea how to fix this 30 seconds delay?

Many thanks for any help, Felix

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.

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.

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.

If I go on any website using OSM data (including OpenStreetMap itself) on Firefox logged into my account, I experience a lot of slowdown. This doesn't happen when I use incognito mode or when I use another browser, so I'm pretty sure there's some kind of cache or something that's connected to my Mozilla account that slows down OSM massively. I've tried clearing all cache and all cookies. I've even refreshed Firefox using the installer and it's still slow. I don't want to bother with deleting my account and creating a new one. What should I do to try and return back to normalcy on OSM?

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"

I am having a lot of difficulty opening websites ( NYtimes, Washington Post) they takes minutes to open. Sometimes minutes more to open article. ATT says line service is fine. NYT says it service is fine and it works on EDGE Any thoughts?

Hi, I'm having some issues with Firefox. I'm opening a website (which I usually visit) even slower than with Tor at the same time. I'd love to know why and how to fix it.

When I try to download anything Firefox Caps my download speed at 10MB/s Other browsers don't. I tried, Edge, Chrome, Etc... they all give me access to my full Gigabit speed. I've attached 2 screenshots with a SpeedTest comparison.

Firefox: 90mbps Edge: 630mbps

Hi to all.

when i try to open an https link firefox show only a white page instead of the document from the link.

I make refresh without fix anything I totally remove firefox and delete also the registry entries and after make a new installation without fix anything.

Any suggestion?

Thanks and regards

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

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.

updated to latest firefox 136.0.1 today and several web pages will not load on first attempt. yahoo.com, google along others indicate that page is preventing this site from loading. I have not encountered any issue with Chrome. Have not encountered this issue with firefox previously but very frustrated user. I any attempted to start firefox in debug mode without any extensions or tools and firefox still encountered the same issue. Any recommendation would be appreciated.

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.

There is a gap between firefox and the frame of the window. There is also a inconsistency at the bottom of the browser where it meets the window. Issue persists in safe-mode and all other firefox channels. Albeit, there is no gap or issue with firefox ESR.

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.

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.
