Firefox Community Forum

I have used Fire fox with https://www.lloydsbank.com/ for s few years without issue. This morning when I go to the website I select Log In > Personal and get the erro "403 Forbidden" this happen on my linux laptop and windows 11 pro pc

Brave browser on the linux pc work and I can log into the website successfully.

I have repeatedly removed/cleared browsing data for the specific site, made an exception for that site too but there is no change. This is obviously a firefox problem as the same error occurs on windows.

I have also disabled my extensions on the linux laptop firefox. My firefox version is 158.0.1 64 bit.

help would be very much appreciated. thank you

Updated Firefox browser for desktop on Mac to 158.0 on 10/15/26

On 10/14/26 using previous Firefox version 157.0 on Amazon.com Prime Video section, pages would load properly and videos could be played properly.

10/15/26 using updated version on Amazon.com Prime Video section, page would initially load properly only to later freeze. Videos could not be played. And freezing could not be corrected unless closing the tab on the browser.

10/15/26 using Safari browser on Amazon.com Prime video section, pages loaded properly and videos played properly.

Clearing cache and site data on updated version of Firefox did not have any effect. Pages continued to freeze and videos unplayable when starting over and navigating to the relevant pages.

Steps to reproduce:

go to amazon.com login to account go to prime video page

expected results video selection appears and user can select and play videos

actual result video selection appear but freezes after a second or two,. videos cannot be played

Repro rate 5/5

Environment Variables Firefox 158.0 Mac OS GoldenGate 27.0.1

Other information Other amazon pages like whole foods and home page and Subscribe & save not affected Just Prime Video page affected

I sometimes experience issues when accessing web-based email services through Firefox and want to understand whether browser settings or extensions could affect them. When using a bulk email service provider such as iDealSMTP, what Firefox settings should users check to troubleshoot email-related issues? Have you experienced similar problems when accessing a bulk email service provider through Firefox?

Today, 2026-10-24, it appears google is blocking me from using most tabs in Firefox. Versions are 115.18.0esr (64-bit) and 100.0b7 (64-bit). Worked fine yesterday. I have various Win 7 versions on my three machines. I've been getting warning messages from google for some time about stopping support for Firefox and I contacted them to get a date, but never received a reply. On one machine, when I start Firefox, it immediately dies. On the other two machines, it only lets some websites run, but not my personal gmail or my HSU student gmail. I was planning to install Win 11 on at least one machine, just have done so yet. I could try upgrading to 115.43.1esr. Yes. I am a bit of a Luddite; I started working in computers in 1977.

I have no issues on other sites, even sites with embedded video content.

YouTube, however, performs extremely poorly whenever it is the active tab. Page loading is extremely slow visually - the page itself appears to be loaded, but elements haven't appeared, and some elements that should disappear when video playback begins (the YouTube logo, or the play/pause icons) persist on top of the video. Buttons and icons on the page are extremely slow to respond, even scrolling is very slow, and sometimes even mouse movement is slow - clicks take anything up to 15 seconds to register, and it takes several seconds for hover highlighting to appear.

Video playback, when it starts, may not actually be shown - that is, the audio plays, but nothing happens on-screen. Pressing pause often takes several seconds.

And, closing and reloading the tab often takes far too long as well - as in, the time between when I actually click the reload or close, and Firefox actually responds.

Sometimes, I will get the warning banner that the site is slow, but not always. If the banner appears, as long as the video is already playing clicking 'Stop' on the banner seems to resolve the issues (but, I can't use functions like the comment box, 'like' button, search bar, etc). If I do this without the video playing, I can't start the video - the playback controls no longer work.

I am reluctant to turn off uBlockOrigin or Disconnect to use YouTube. I've tried disabling other extensions to see if it makes any difference, and I've also tried switching off hardware acceleration and using the recommended performance settings instead. I haven't found any way to force YouTube to only show videos at 720p at most, but I've tried switching videos to 720p (and where I can, away from 60FPS). It makes no difference.

Are there more fine-grained performance settings that I'm missing? Is there something obvious I'm missing? It seems that it's literally only YouTube that performs this badly, and only for about the last two weeks.

Until a week or two ago, Amazon Prime Video worked without a problem in my Firefox browser. Now I cannot get Prime Video to open any show (the play button keeps spinning and is not clickable). The website is unresponsive as well, although it loads. Here is what I have already done for troubleshooting.

1. Updated Firefox to latest version. 2. Cleared cache and cookies. 3. Checked for hardware acceleration issues. 4. Disabled IPv6. 5. Tested in Private mode with all add-ons disabled. 6. Disabled Enhanced tracking protection.

This is an issue with Firefox since Prime Video works fine on other browsers.

If I load multiple tabs of this site it is really slow or keeps spinning. Then all of a sudden it will load fast. It runs good on Chrome but I don't want to switch to Chrome.

After the recent Firefox upgrade a couple of days ago, I am unable to get to my Questrade login page. I click login, I get a white page with a message in bottom left hand corner "transferring data from login.questrade.com..." and no further response. I am able to login with MS Edge, and Firefox is able to access all my other websites except this one.

I have run through all the things to try in the Firefox support article "Firefox can't load websites but other browsers can" to no effect.

• cleared cookies & cache
• cleared recent history
• turned off DNS over HTTPS
• Disable IPv6- changed to true
• changed Proxy settings to No Proxy

I've turned off Bitdefender firewall and antivirus apps to no effect and ran a full system scan with Bitdefender. I really don't want to have to use a different browser each time I want to access questrade site. I would really appreciate any advice as to what else I could try to resolve this issue. Thanks so much!

I tried to share my screen for my test at web https://my.codingolympiad.org/compatibility-test but it always says Screen sharing: Error occurred: getDisplayMedia requires transient activation from a user gesture. I need help with this

Using Firefox browser is resulting in a message that states that Firefox is not operable with mail.fcconnexion.net. Your info is stating that there is a problem with the website. If that is the case then why using Microsoft Edge or Chrome allows access?

Ever since I downloaded the latest version of Firefox on my iMac, the Amazon Prime Video website is broken. I want you to un-break it. Stop changing things that work and make them not work.Stop changing things that work and make them not work.

Hi,

I'm using Firefox on a Mac, and I'm having trouble dragging screenshots from my desktop into ChatGPT. I can upload images using the "+" button. Dragging and dropping images works in other browsers. In Firefox, dragging images into ChatGPT is unreliable or stops working. I have tried restarting Firefox and disabling add-ons, but the problem persists. I also tested a private window.

Could you help me identify the cause and suggest a solution?

Thank you!

From one day to another the website I use stopped working and can't figure out why. I can access the website from Microsoft Edge so I know it's not the website. I pressed F12 and got this info:

Just started happening a few days ago. On Lifepoints (lifepointspanel.com) , surveys used to be accessible for one to do. Starting a few days ago , that changed and all now come back with "Try a different survey". No changes on my end. Support at the site indicates it is a browser issue. Any clues? Been using FF all along and it is up to date.

Hello,

For some inexplicable reason, when I visit any Wikipedia page (as of Thursday 8th October 2026), the pages display with a huge oversized font that also impacts the format and layout of the page in my browser. I have not made any adjustments on my PC to increase font display size. Wikipedia is the ONLY website that displays in this manner.

I am running Firefox 115.42.0esr (64-bit), which appears to indicate Firefox is up-to-date on my Windows 8.1 desktop PC. Please note that I am still running Windows 8.1 on this device out of choice.

I reported the fault initially to Wikipedia itself, and the response is that any fault is at my end. I have visited the same Wikipedia pages via Chrome Version 109.0.5414.168 (Official Build) (64-bit) and the pages display normally.

I have attached a sample screenshot to illustrate.

Any ideas how I can resolve this issue please?

Many thanks - Dean

Why have amazon prime videos stopped working with firefox and how can I fix it?. It was working last week and suddenly stopped. Now all attempts to play videos are met with a permanent Amazon hourglass.
