Firefox Community Forum

I just accepted a FireFox update and now it will not load any new pages. In your previous update it no longer loads the popular page previews either. I am on windows 10 for now and will be installing Windows 11 in the next two days.

I have been a great supporter of FireFox and Mozilla and must say you guys are dropping the ball. Less and less clients are building stuff to work with your browser. Its making it difficult.

One recent example is Google Meets ( I hate it, but others use it) It wont run on your browser. Job applications often fail on your browser too.

The Bitwarden extension no longer works

If there is anything you can do today to get your browser to work again, Ill continue using it. But unfortunately I can no longer spend time troubleshooting it.

Not able to upload my password files. I get an error message that states: Unable to Read File Firefox does not have permission to read the file. Try changing the file permissions. How do I change the file permission?

I have an internal site that now gives

Not Found HTTP Error 404. The requested resource is not found.

It started on 9/19/25. It's not the site. In fact I did a refresh on Firefox and it work. However if i I turn on the Menu bar and restart Firefox it's broke again.

Whenever I try to open Github specifically I get:

Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for github.com. The certificate is only valid for the following names: cloudflare-dns.com, *.cloudflare-dns.com, one.one.one.one

Error code: SSL_ERROR_BAD_CERT_DOMAIN

I spent time looking into this, used a new IP address and tried updating the certificate for github, however I'm not particularly skilled when it comes to this, so any assistance would be much appreciated.

I've been trying to get Firefox to save cookies for a few desired websites (bank, investment accounts website, Sync... and of course Firefox/Mozilla itself) so I don't have to constantly use the 2FAs for those accounts. Firefox refuses to keep me logged in to my Mozilla/Firefox account. Every few hours -- or at the very least, after a machine shut-down -- I have to re-login if I re-start Firefox.

I do not use the Firefox Password Manager; it's unchecked in Settings. Nor do I use the Autofill options in Settings. I use the Bitwarden Extension (set to Never for locking/logout -- because this is a home computer) for Firefox to log in to my sites, with a separate authenticator app, Authy.

The Firefox Privacy & Security Settings for tracking cookie blocking are the Standard ones; I haven't done anything to customize them. Further down on that page, I've tried leaving the box blank for clearing cookies on exit. I've tried checking the box and setting up exceptions for those few sites I'd like to login to without having to go through the 2FA rigamarole. I've done multiple Refreshes, clearing of History, uninstall/reinstalls including deletion of every Firefox profile and anything hinting at a connection to Mozilla or Firefox in all Users on the computer, including all the AppData folders. A few days ago, I even deleted the Mozilla/Firefox account and set up a new one with a different email address.

Nothing seems to work. Most recently, Firefox still had all the relevant cookies after the computer was shut down overnight, but an hour into my day's work, after closing Firefox and re-opening it a short while later, all the cookies are gone once again!

None of this was an issue about three months ago. I could save the desired cookies, get rid of other ones, use private browsing, etc. etc., with basically the same set-up and with the Mozilla/Firefox account I had had for years. Now, I've had to delete that account in an apparently vain effort to try to clear out anything "Mozilla" from this computer -- and it didn't work anyhow.

(I posted about this same issue a week or so ago, but didn't receive any responses and have now deleted that Mozilla/Firefox account -- see above -- so this message is an update.)

Здавствуйте. Играю в браузерную игру в Мозила фаерфокс и все еще наблюдаю проблему самовольной перезагрузки вкладок. Я уже писал и описывал эту проблему но вы так ничего и не исправили. И вот сейчас я обновил Фаерфокс и снова эта проблема. Поблема вот в чем: Я играю в игру в полноэкранном режиме где идут или выполняются активные игровые действия, так же я делаю активные действия мышью. И вдруг браузер САМ выводит меня из полноэкранного режима, начинает обновлять вкладку с игрой. Из за этого весь игровой процесс прерывается и мне снова загружает игру! Честно сказать это уже надоело. Не возможно играть нормально, в любую минуту браузер начинает сам обновлять вкладки. Пишу вам второй раз, исправьте это. Скриншот с игрой я вам приложу, а так же опишу название и айди игры на платформе соцсети Вконтакте. Игра "Клондайк - Пропавшая экспедиция" Номер игры App3083242. Или ссылка на игру https://vk.com/app3083242

Надеюсь вы исправите наконец эту проблему!

The Firefox Icon in the top left now has taken more space below it next to the bookmarks, and after closing and opening the browser, the Icon is now sharing space with my tabs. Not sure what caused it, disabling all extensions and themes did nothing. If I can't figure anything out from here I may try to reinstall Firefox entirely, would just rather not have to go through that and have to set everything up again.

The last two updates have destroyed Firefox on my M3 Pro Macbook Pro running Sequoia 15.3.1. Freezes video, then freezes the program. Have to bail out with Force Quit. How do I go back to one that works?

I can't login to my AARP.org account using Firefox, even after clearing cookies and site data. However I can login using Chrome. What is the fix for this?

I noticed that on that exact day of the update Audible books will not play as they did previously on the same day prior to update. They play on every other browser but firefox.

For past few weeks, Whenever I try to update FFX on windows 11, it fails. It takes me to another screen and tells me to download Firefox. When I try to download it , it aborts with this message.

"download.mozilla.org has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site."

To download Firefox with new version I have to use another browser but no choice. Then with new version of Firefox, I have faced the same issue of update and used same approach to update firefox to a newer version.

This error appears for some google sites as well but the same occurring for firefox download site itself is not understood.
