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.

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...

Good day. I'm thinking of deleting Firefox. It's simply impossible to use it on some sites. For example, I can't write a comment on YouTube because the browser freezes. Page scrolling and controls also freeze. I turned off browser extensions, but it doesn't help. I have 48GB of DDR5 memory and one of the best processors available today...

Hi,

I know that Google's doing everything to push everyone to use their spy software Chrome, but now youtube is really slow (15 seconds to stop a video when I click on the video, same to start it, 10 seconds to open a new dongle for youtube, and roughly 5 seconds waiting in others services).

Also, some others website work very badly or sometime not working at all with Firefox, why ? I have Ublock on Firefox too

I came back to Firefox for my privacy but if 35% of websites not work with it, not great. Have you an idea how to solve this problem ?

Thank you,

Matt

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.

firefox has always opened instantly when i click it, but within the past few weeks it takes 10 to 15 seconds to get going. computer restarts don't seem to make any difference. any thoughts?

I'm trying to log into this page: https://accounts.firefox.com

The sign up or sign in button doesn't work. The first time I click it, it immediately refreshes. I click again and nothing. On the 3rd click, it just spins for 30 seconds then goes back to being blue. This continues every time I attempt to click further.

I can login on this page just fine using Firefox on my android phone. I can also login using the Edge browser. Matter of fact, I had to use Edge so I could post this issue.

This is a completely fresh install of Firefox, on a completely fresh install of Windows.

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.

So, I'm trying to sign in to D&D Beyond with my google account. It works fine on my phone but when I try to do it on my desktop it just endlessly loads. I've already tried turning my pc off and on again and clearing cookies. Has anyone else had a similar problem.

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.

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

I've been having a problem with FF for the last two weeks. At times downloads accessing web sites are slow or even get hung up. Usually reloading or refreshing the page fixes the problem. I tried a FF safe boot and things seemed to work better. I have had the same four extensions for quite awhile. Are there any reports of UBO causing issues?

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

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?

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

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.
