Firefox Community Forum

Hi Mozilla Community,

I run a food-focused website that showcases restaurant menus, and I’m currently having trouble with one specific page—https://olive-garden-menu-with-prices.us/—which loads significantly slower in Firefox compared to other browsers like Chrome or Edge.

The page is mainly text and optimized images, and I’ve minimized scripts as much as possible. Still, Firefox seems to hang while rendering or takes a long time to fully display content. Could this be due to any specific Firefox rendering behavior, caching issues, or something I may be overlooking?

Any tips on how to debug or optimize page performance specifically for Firefox would be really appreciated. Thank you!

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.

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"

The server at 192.168.1.1 is taking too long to respond.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

How do I change the time out to a longer time?

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.

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?

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.

some times the Youtube video's won't load i thought that it's my network glitch but my network is good only in this browser the videos won't load sometimes and some website's like amazon also won't load some times it keeps on loading but nothing will be loaded . i need to restart the whole browser to make it work please fix it Zen browser .

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.

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

WTF IS WRONG WITH MOZILLA?

So, I'm browsing a website (shopping), going back and forth through its menus/categories and also opening tabs in the background, then every few minutes the whole browser goes blank/grey and the tabs "dead"... they're not closed just blank and I cannot go backwards or refresh... I have to close the tab and reopen it from history...

Did I explain this clearly? I've been putting up with this for 2 weeks, but now I've had it... I'm staring at a blank tab I cannot revive - refresh or back button don't work, AND another tab which is displaying a "Loading wheel" and also frozen...

I've only recently started using Firefox (I use 2 other browsers above this - each with a distinct purpose, and also started giving-in to Edge as a 4th, despite being opposed to everything Microsoft for 20y).

If I continue to experience this in the next couple of weeks, bye bye Mozilla...

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

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.
