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.

When loading webpages, it will often take 60-90 seconds to load the page. I've only seen this happen when loading the page for the first time, once it loads navigating through subpages is seamless. It doesn't seem to be tied to any particular domain, I've had it happen randomly on gaming websites, tech websites, even google searches. The most notable coincidence is that in the networking tab of the developer console, it always(?) takes almost exactly 30 seconds on DNS resolution, 30 seconds on Connecting, sometimes a 30s Blocking element, and then the remainder is near instantaneous; screenshot attached. My network is fine, I'm able to play low-latency games without issue, and Chrome is not exhibiting the same behaviour.

Things I've tried to resolve:

• Restarting computer -- issue has been persisting for months
• Created a new Firefox profile -- still showing the same behaviour
• Disabling all addons/testing Troubleshoot Mode
• Proxy settings in Firefox -- No Proxy and System proxy settings are both showing the behaviour
• Disabling DNS over HTTPS

Any help would be greatly appreciated.

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

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 .

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.

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! ;)

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.

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.

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?

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.

Seems I've noticed an issue with playing of YouTube videos the last few days. It seems that either the video(s) is slower to load and/or is slower to play. While it's not terribly slower in human time it's slower than normal in computer time. I'm not having this problem in Chrome. Cookies and cache are cleaned multiple times a day. So, I'm a little stumped as to why I'm having this issue. Any comments would be appreciated. Thanks

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?

When I open any stream, it takes about 2.5 seconds from the start of the page loading to the appearance of the stream image and playback. For comparison, in version 137 it took about 1.0 seconds.

I tried to launch the browser (Firefox 138.0.1) in troubleshooting mode, and also created a new profile, but the problem remained.

I also downloaded portable versions: 137.0.1 - everything is fine. 138.0 and 140.0a1 - slow loading.

I also have Zen Browser installed (the latest version is based on 138.0.1) - everything is fine.

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.

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.

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...
