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

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?

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! ;)

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...

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.

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...

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.

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.

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

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.

my firefox is taking forever to load any type of page, and in addiition the thunderbird is also slow. I re-downloaded mozilla, but it is still downloading so skow. just last two days, and when I say slow like 2 minutes to open a page. HELP

OS: Windows 10 Pro 64-bit with all the latest Windows updates installed; running Windows version 23H2. Firefox release I'm having problems with: 137.0.2.

Just upgraded to release/version 137.0.2. The first time I open Firefox each day it takes about 2 to 3 minutes for ANY website to load. Sometimes when a web page does eventually load none of the images display.

I have tried same websites using Google Chrome AND Microsoft Edge. Websites don't have problems loading using either of those 2 browsers unless I have Firefox open in another window. If they load slowly, as soon as I close Firefox, web page load quickly in Chrome or Msoft Edge.

Not a RAM problem because I typically have around 20% of my RAM being used.

Did not have any of these problems using Firefox version 137.0.1.

UPDATE: Thought maybe it was one of my add-on/extensions so I checked for updates. Four needed updating. Made the updates and website still no loading properly.

Hello,

I have problem with some specific web pages like below that keeps loading and refreshing again and again until account gets lock.
