Hello, for some time now I've been experiencing a number of problems with the latest Firefox updates.

Today I have version 152.0 (64-bit), which was updated again this morning. I restarted my mid-2015 MacBook Pro Retina. I have fiber optic internet, which is very high speed.

I've been using Firefox for over two years.

1) For the past eight days, I've been experiencing many problems with Google Meet; I get freezes, audio and video dropouts...

2) For the past three days, I haven't been able to log in to this website: https://creators.spotify.com/pod/login

3) For about ten days, I've been having trouble logging into my Stripe dashboard, with significant slowness and/or crashes.

4) In Notion, I'm also experiencing significant slowness, with pages taking a long time to load.

In short, several problems that I didn't have at all a month ago or before.

But now it's a nightmare.

I don't have any of these problems in Safari or Google Chrome.

So what's going on in Firefox?

Why is it such a hassle?

Thanks for your feedback.

Firefox has just updated on my Windows 11 PC at around 1100 17/06/2026 and now I cannot access my Spanish banking online with Banco Sabadell.

When I try to log in I get a message saying 'the process cannot proceed because of security issues.'

I could log in prior to the update and I can still log in using Brave.

By process of elimination I deduced that it must be something to do with the update.

There was nothing wrong everything was running perfect and smooth but then out of nowhere my youtube froze and I couldn't press anything on youtube tab, I could still close it or press the buttons on the sides/corners but on the youtube, it also doesn't refresh, this only happens on youtube and only on firefox when on other browsers, yes I unchecked hardware acceleration, I restarted my firefox many times, I cleared the cache, today I turned my adblockers too, i thought it turned into how it was before but then it froze again and now I couldn't even see youtube it was just black screen on that tab, like what do I do here, do I switch browsers? It eventually starts playing again after I wait for some minutes but I don't want that, I want it to work like how it did before this happened. Why did it even happen?!

Just enquiring if anyone else is experiencing problems upload things through Firefox Nightly. I first noticed it around a week ago. I was using ChatGPT and uploading images, drag and drop, and I could get one or two to work, after that, the uploading buffer wheel would freeze. Completley clearing the cache would fox the issue, but it would reappear after one or two uploads again. Same issue, uploading to Grok. Today I tried uploading a couple of images to the The Movie Database, and again, same issue. If I switch to Chrome, no problems. If I use Edge, No problems. Funnily enough, when the issue presented today and I tried to post here, I got locked on the Fastly Client Challenge and had to use Chrome to post here. (I don't know if thats related, but squirrely either way) I have reported the issue on Bugzilla, but just wanted to know if anyone else has this issue. Thanks in Advance. Oz.

Over the past week or so, I've been finding that Youtube videos don't start from the very beginning - the very opening is missing.

So as examples, you're playing a song that you know starts directly on a beat, but that first beat gets missed, or there will be an opening sentence such as "Everybody is talking about the latest... " and what you hear is more like "Vrybody" - you can clearly hear that It's slightly off.

This relates to Firefox in three ways.

My initial thought was that there is some conflict with using an Adblocker (uBlock in my case) as Youtube is trying to force a pre-video ad that won't play, but even with the adblocker disabled the problem persists.

I then cleared my Firefox Youtube history so it loads as a completely fresh version - but the problem is still there.

Finally, I tried the same video on Chrome to see if this is definitely a Youtube issue...and it plays correctly without a problem.

Therefore, the problem seems confined to Firefox but I am unsure where - what setting needs to get tweaked to sort this out?

Windows 10, Firefox v152.0: I'm logged in to my account with fidelity.com and visiting a page to get information about an ETF: https://digital.fidelity.com/prgw/digital/research/quote/dashboard/composition?symbol=XXXX (XXXX being any valid ticker symbol; makes no difference what) The information is organized within the page with a set of sub-tabs (?): Overview Chart+ Composition .... (+ 6 more) Much of the information displays normally, EXCEPT: Under "Composition": "not currently available" Under "Distributions & Expenses": "not currently available" Under "Performance & Risk": there are two sections, but only one of them displays normally Under "Statistics": three sections, only one displays normally; the other two "not currently available" (see attached image) I've checked with Fidelity support, and they verified no issues at their end--identified as a browser issue since the site doesn't have this problem using MS Edge I've cleared the cache, I've turned off enhanced tracking protection, I've temporarily enabled all scripts (NoScript extension)... none of these actions helps FWIW, I also enable Privacy Badger and Malwarebytes Browser Guard, but neither claims to be blocking anything

Firefox 152.0, latest Windows 11 25H2 update on HP TP01-1036. I have tried just about all the AI fix suggestions but nothing works to fix the following problem:

When viewing the Yahoo.com News page, I scroll vertically down to see each article...one after the other. When I come to an article I want to read, I left click it. The article opens within the present tab and is closed by clicking the red "X " at the upper right hand corner of the article; which in turn, returns me to were I was before opening the article. However, eventually, after a few articles are read, when closing an article, the cursor will jump back to the page's first article instead of bringing me back to where I left off on vertical arrangement of the news articles'? This has been happening for around the last one to two weeks. Nothing else seems to be out of wack.

on some sites, when I try to sign in I have entered my login information, but when I hit enter or submit for instance bigfishgames.com nothing happens. When I am on my Drs portal after I have entered pages of information and hit submit, again it does not get accepted. Soooo, I have to leave firefox and go to a different browser. Any help would be greatly appreciated, it is very frustrating when this happens. It is so frustrating that even though I have been on Firefox for many years I am thinking about using a different browser.

recent firefox update can no longer copy and paste when creating a blog post in Squarespace, I have been using squarespace for around 15 years for my websites and I have never seen this issue, Firefox 15.1 installed and all of a sudden when trying to create a blog post in Squarespace, when I right click a text box pop up and it no longer says paste so I can no longer copy and paste text - this is more than a little annoying, you will not be surprised to know that I am now using Chrome to create my posts, there is no issue in chrome. I am a firefox geek! how can i solve this problem, I just did another update from Firefox, the issue remains I have been using computers for 40 year so I am not a novice but software glitches, I am lost

If I upload a jpg image via the + in the Gemini prompt it fails with an ! or doesn't give the (up pointing arrow) execute option prompt. Do usual things and even clean installed Firefox. Same on 3 windows 11 PCs 2 of which not my own hence not configured the same. All did work until latest updates. No browser extensions antivirus temporarily turned off. Same in, private and safe mode. All work fine on Chrome or Edge (sorry to swear at you) A work around is to load them via Google Drive or Photo and pull them from Google platform.

Unable to upload any images to Gemini. Working fine on all other browsers. Images always fail unless security levels set at lowest. When the do upload the action button does not become active

Content Security policy blocks essential scripts no matter what I do.

It's new Firefox installation, Troubleshoot mode, Enhanced tracking disabled, I'm not on VPN, can log into X.com in another browser just fine.

It's the reason #1 I don't use Firefox. I thought the issue would be fixed but it has been like this for long time.

Yet whatever I do, whatever I turn off this pops up:

Content-Security-Policy: The page’s settings blocked the loading of a resource (default-src) at https://abs.twimg.com/responsive-web/client-web/bundle.Conversation.721fc4aa.js because it violates the following directive: “default-src 'self'”

The screenshot is from Zen, but it uses Firefox and the issue is the same in Firefox.

In Firefox, a lot of my pages are not loading at all...the tab just shows that the website page is loading but it never does. The menus of the website will appear, but pages are not loading. This is not happening in MS Edge. I prefer Firefox, but lately have had to go to MS Edge to load pages. What could be happening?

Hi,

I’m facing an issue with my website’s fine checking tool on Mozilla Firefox. My website is evgfinescheck.com , and the tool works fine in some browsers, but on Firefox it doesn’t load properly and sometimes shows an error.

I am already using the latest (updated) version of Firefox, so the issue is not due to an outdated browser. The tool either fails to fetch data or doesn’t respond as expected when users try to check fines.

I’ve checked basic things like internet connection and browser updates, but the problem still persists specifically on Firefox.

Can anyone guide me on:

What could be causing this compatibility issue? Are there any common JavaScript, API, or CORS-related problems specific to Firefox? How can I debug or fix this issue?

Any help would be appreciated. Thanks!

Hi Everyone,

I've been having this problem for a wee while when I'm browsing facebook (which works better in Chrome) the site on firefox and as well as messenger is really laggy and I'm wondering if there is a hidden setting that I should change to improve this?

I only have adblock addon installed and I cleaned out the history and browser cookies ect but the problem still remains.

Any ideas? Thanks Rob

For a while firefox has been having issues where on youtube in particular when tabs are closed they will continue to play audio for a bit after they are closed. More recently I have closed tabs and the audio keeps on going indefinitely after the tab has been closed. This is on the latest firefox (151.0.4 64 bit) on windows 11.

This only seems to happen with youtube and in general youtube playback is buggy, slow, and lags the whole browser taking several seconds to switch tabs to or from a youtube tab or even close it.

Hi, I have tried all the changes to settings etc but still cannot load certain web pages, i just get a white screen, The pages I cannot load are things like: Facebook Discord Amazon Seller Central Payment screens

This is just a couple I can remember, I have tried other platforms like edge and these sites work fine. Please advise as I would rather use Firefox Thanks Tony
