Firefox Support Forum

As of 2024 06 20 there are many websites that I cannot login anymore one being Facebook with this message:Update Your Browser You’re using a web browser that isn’t supported by Facebook.

Hello Mozilla community,

I'm encountering a perplexing issue with Mozilla Firefox that I hope someone here can shed some light on. Whenever I set Mozilla Firefox as my default browser, I experience difficulties accessing my website. The site continuously buffers but never fully loads, leaving me unable to view its content.

However, when I switch to a different browser as my default, such as Google Chrome or Microsoft Edge, the website loads without any issues moreover my website is related to Picoworker which runs smoothly on other browsers (Screenshot is also attached). This leads me to believe that the problem might be specific to Mozilla Firefox.

I've tried troubleshooting by clearing the browser cache, disabling extensions, and even reinstalling Firefox, but the problem persists. I've also checked for any errors in the browser console, but nothing seems out of the ordinary.

Could there be any compatibility issues between my website and Mozilla Firefox that are causing this problem? Or is there something else I should investigate to resolve this issue?

Any insights or suggestions would be greatly appreciated. Thank you in advance for your assistance!

I've recently had trouble logging in to some websites but not others, most recent example is Bandcamp. My login credentials are correct and work on mobile and other browsers. I have tried deleting my cache and cookies to no improvement.

I'm a long-time Firefox user (I probably came here straight from Netscape!) but lately, I'm starting to see tons of issues, often after every update.

Things that might help: 1. I'm mostly a Windows user, although I have a Mac. I have a LOT of Windows boxes (don't ask) - a couple of work laptops, some private laptops, a couple of micro-desktops that are connected to TVs and so on. This might be relevant, because they're all synced.

2. My profile is pretty old - over 10 years.

3. I've entirely disabled any ad-blockers or add-ons.

So issues happening on multiple machines in the last 24 hours: eBay. Over the last few days, when logging into eBay, if I do a search, I can't change any of the filters along the top Condition, Location, Sort: Best Match etc. I can click on them, but nothing happens.

GoFundMe. I tried to donate tonight and when it toddled off to Paypal, it came up with some kind of Localhost error after I clicked on Submit. Did it on Chrome, and it worked perfectly. Fortunately, the money didn't come out multiple times.

Oracle E-business. I'm sure many of you use this at work. I genuinely can't login to this using Firefox unless I use a private window. I've cleared my ENTIRE cache. Even went into the Folder and manually cleared it all out. If I try and login without being in a private window, I get "Your session is no longer valid or your logon information could not be reestablished from your session."

This is all since the last update to 127.0

Hello!

Started up Firefox today and these whited out boxes started appearing over my search bars and random part of the screen, such as the descriptions of different articles on my home pages, extension and theme information in my settings, and different tabs (see pictures 1 and 2). The text is also white, making it almost impossible for me to see what I'm typing or selecting in the search bar (picture 3).

I've already tried some tips that I found on the forums such as changing the hardware accelerator, making sure my extensions and add-ons were up to date, etc. When I go into troubleshooting mode, the boxes disappear and Firefox functions normally, but when I tried turning off all my add-ons and themes on the regular browser, the problem still wasn't fixed. I did a full refresh of the browser, hoping that would help to reset whatever was causing the issue, but that didn't help either.

Any advice or troubleshooting tips would be greatly appreciated!

Hi, I have applied the latest updates on my Zimbra server (Ubuntu 20.04) last week and since then the emails contents are not displayed anymore in the classic web client, they are displayed only in the modern web client, I will attach same email in both clients to compare. In using Google Chrome there is no such issue

Over the past week or so, Youtube videos take a while to start, and will at times just stop and buffer. I turned off uBlock Origin for Youtube, and I have Youtube Premium, but this issue is still happening. Ookla speed test is 569.32 Mbps download, and 23.50 Mbps upload. My Firefox is set to automatically update. Current version is 127.0.1

wise.com is a site I've used for a long time with Firefox. Now I can't log in. Access is still available from the Chrome browser, but I prefer Firefox

Twitch shows error 2000 when I'm trying to watch a video on it. When I watch lives, no ploblems happen. It loads the videos with VPN on. Also other browsers like Edge load videos without VPN.

Hi,

am running firefox 127.0.1 on a windows 11 desktop. Numerous sites that use a captcha to login fail. In other words, the captcha never loads and I cannot login to those sites. Such sites include teamfaderpro, Coursera, and bandcamp. All logins fail as the captcha is required to be passed prior to logging in, but the captcha never appears and so when I try to log in, nothing happens and I cannot login.

I have tried the above same sites on the Edge browser and have no such issue, the captcha shows and I can login.

Just FYI, the agent switcher setting change recommended by others previously is not suitable. When I tried that fix I was unable to access a considerable percentage of the internet due to some cloudflare issue, so the agent switcher setting is not an option. So far, I have tried all recommended settings to fix this issue and nothing has worked.

I am surprised no one else is having this issue.

Any help is appreciated, or at least inform google/mozilla about this issue as it has been ongoing (on and off) for me for many months. And yes, this problem is persistent for me at the moment, it remains despite rebooting windows, despite clearing cookies and cache (which I have set to automatically delete when exiting firefox).

Hi there! I've been having problems with youtube not working in firefox lately. It's ONLY in firefox that it does this issue in, I've tried it in other browsers. Youtube tends to just....stop buffering in firefox for some reason? My internet connection is not the issue so I'm not sure what I could do to mess with it, I've done a fresh install of firefox, I've cleared cache and cookies. I'm genuinely at a loss.

It takes FOREVER for it to actually s tart up in the video too. The video plays fine until it just...stops buffering and takes 5-10 minutes to load. As mentioned before this is only an issue in firefox.

I am using Firefox version 126.0.1 (64-bit) on MacOS Ventura 13.0. I cannot interact with any Nature journal webpages (https://www.nature.com/ , https://www.nature.com/neuro/ , etc). I can only scroll, no clicking on links, highlighting or anything else you might expect. Not sure if this is specific to my computer/browser/extensions or if others are experiencing this and what steps I might take to resolve?

Upgraded to version 127.01 and can not use it to log into some important (to me) websites. I can use Microsoft Edge without problems. Tried disabling VPN, clearing cache, rebooting, etc. without resolution. Similar problem in the past that somehow resolved spontaneously after several days (not sure why).

I'm having problems logging into any/all Wordpress dashboards following the latest Firefox (V127) update. The 'verifying' screen continues to cycle but doesn't produce the login screen. I can get them to work in Troubleshooting Mode. This also works when the 'New Tab Override' Add-on is disabled too. I've tried ALL of the recommended custom tab plugins with the same results, so it suggests a common incompatibility.

Have cleared cookies and browser cache. WP login works on all other browsers.

Would be grateful for any help and/or suggestions.

To whom it may concern, Hi, I haven't been able to access this website for a couple of weeks and have never had any problems opening it in the past. Have contacted the bus company and they do not have any issues at their end. This is the error message I still continue to receive and don't know how to correct:

Unable to connect An error occurred during a connection to www.premierillawarra.com.au. • 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.

Hope to hear from you soon

I using an ASIS Latop model X756U running the Windows 10 Operating System. Firefox is my default browser.

I installed the Opt-Out Google Analytics Extension on 9 June 2024. The intent was identify which of my applications are using Google Analytics by testing them and seeing which ones were broken.

Having done that I removed the Opt-Out Google Analytics Extension from the Firefox Extension list.

Unfortunately the extension remains active and continues to disrupt my browsing experience.

How do I remove this extension permanently?

Hello there,

I am using WordPress, and the Video Player Element does not display on Firefox, although in HTML code is visible. The same problem appears in Firefox troubleshooting mode if it helps.

Do you have any idea what causes it, and how can I solve it?

I use Firefox (currently on version 127.0) and starting this weekend I noticed a strange behavior. When I initially go to the NPR.org site (and only that site) everything works fine, but once I scroll down past the first two articles all of the links on the page stop working. The cursor that usually changes from an arrow to a finger does not change, the links do not change color as they should.

This only happens on NPR.org, and it only happens with Firefox (I can use Chrome at the site works fine.) Therefore I assumed that something changed at NPR.org so have reached out to them, however, I thought I would ask your team if they knew of anything going on?

Thank you tom balent

Youtube audio is extremely slow, I reckon at 10%, but the video is fine and can be sped up or down. The problem persists even in troubleshooting mode, after cache clearing, hardware acceleration turned off, enabled DRM and widevine, driver updates, in private mode or not, logged in or not, firefox restarts, computer restarts.

But Youtube plays fine in Chrome and Edge.

I dont think I didnt anything drastically different, or updated win10 or firefox, or messed with anything. It was working fine a day ago.

Is there any way to reset something?
