Hello,

I'm troubleshooting a Firefox Desktop issue that I haven't been able to reproduce consistently in other browsers.

I use a browser-based precious metal calculator that performs calculations instantly using JavaScript. The page loads correctly, but after changing several input values and navigating between tabs, Firefox occasionally continues displaying an older calculated result until I perform a hard refresh (Ctrl + F5).

I've been able to reproduce the issue consistently using this scrap calculator scrap calculator. The page loads normally, but Firefox sometimes continues displaying an older calculated value until a hard refresh is performed.

The page itself loads normally, and there are no visible JavaScript errors in the Browser Console. However, the displayed value sometimes does not update immediately after changing the weight or purity inputs.

So far I have tested:

• Firefox Troubleshoot Mode
• Disabled all extensions
• Cleared cache and cookies
• Tested a new Firefox profile
• Disabled Enhanced Tracking Protection for the site

The issue appears only in Firefox Desktop. Chrome and Edge update the calculation instantly under the same conditions.

Has anyone encountered similar behavior involving JavaScript-driven calculations, form inputs, or page caching in Firefox?

Are there specific Firefox settings or diagnostic tools I should check to determine whether this is related to caching, page state restoration, or another browser feature?

Thank you for any guidance.

Здравствуйте. Я установил сертификаты по инструкции, которая лежит на s.sber.ru/70VQ2B . После этого в мозилле не прогружается полностью окно входа на online.sberbank.ru, не видно содержимого фреймов (сейчас попробую сделать скриншот). В Microsoft Edge работа нормальная. Удаление сертификатов, перезапуск браузера и компьютера не помогли. На других компьютерах ещё не проверял. Посоветуйте, пожалуйста, что можно сделать. Windows 10, Firefox 153.0.3 (64-разрядный).

Russian language Уважаемые господа, мне нужна помощь в удалении моего эккаунта mazur.farmamed@gmail.com. По рекомендации, я создал еще один эккаунт, моей жены getochka.mazur@gmail,com, регистрация прошла успешно, к нему я попытался подключить дополнительный эккаунт mazur.farmamed@gmail.com, но ничего не получилось, так как к моему эккаунту привязана возможность вторичной авторизации и изменить пароль и ввести 6-значный код я не могу. Поэтому самым простым способом, я прошу удалить мой эккаунт mazur.farmamed@gmail.com. Я его заново создам и определю вторичную авторизацию к моему телефону +79184844844. Электронная почта у меня работает постоянно и мне хотелось бы продолжать пользоваться эккаунтом firefox с именем моей почты mazur.farmamed@gmail.com , а не моей жены getochka.mazur@gmail.com. Прошу ответить на мой e-mail: mazur.farmamed@gmail.com. Надеюсь на Вашу помощь, С уважением, Андрей Мазур, +79184844844, e-mail: mazur.farmamed@gmail.com 09.08.2026 г.

After the last update, Firefox won't open. Instead, I get this message:

"Firefox is already running but is not responding. The old Firefox process must be closed to open a new window."

I have closed it within the error message but the error message comes back each time I try to open Firefox.

Please help, Deb

MY FIREFOX IS HAVING AUDIO ISSUES. THE VOLUME INCREASES BY ITSELF IT HAPPENS USUALLY IF I ENTER OR EXIT FULL SCREEN MODE, OR IF THE VIDEO OR MOVIE STOPS TO BUFFER FOR A MOMENT IT WILL COME BACK ON AT 3 OR 4 TIMES THE VOLUME. ITS A IRRITATING REGULAR OCCURRENCE. IVE TRIED SETTINGS, AND UPDATES BUT NOTHING SEEMS TO FIX IT. IT SEEMS TO HAPPEN ON ANY WEBSITE I USE. (YOUTUBE, SEVERAL MOVIE WEBSITES AND CARTOON WEBSITES. ITS BEEN GOING ON FOR A COUPLE OF YEARS AND ITS VERY FRUSTRATING. I HAVE TO CONSTANTLY READJUST IT IN AND OUT OF ALMOST EVERYTHING I WATCH. HOW DO I FIX THIS ?

It was working just fine, and suddenly it stopped working. I hadn't rebooted my computer for over a month, and accidentally popped the circuit breaker the computer was connected to, so it rebooted for the first time in a long time. No other issues except Firefox will not connect to the internet when Proton VPN is running, but Firefox works just fine when the VPN is turned off.

I updated to the latest version of Firefox, so I assume that's the same thing as reinstalling it.

Proton VPN allows you to do what they call "split tunneling", where some browsers are excluded from the VPN (Firefox) and other browsers are always behind the VPN (everything else). I use Firefox as a secondary backup browser when the VPN is a problem and I don't want to turn it off.

I ran the Firefox "Safe Mode" and that failed to connect as well. I don't think it's the VPN? But maybe?

Any help appreciated, and thanks in advance.

currently running 153.0.1, in Windows 10 I started having trouble with web pages not working (I have auto-tab discard, so after a while the pages go dormant and when I go pack in they have to refresh) only they wouldn't refresh

I'd hit refresh and it would stay blank but if I opened it in a new tab it opened fine (noted this first in tumblr and youtube - probably since previous to last update) also opening links from an 'affected' (youtube video page that stops working) will also have those new tabs blank and eternally trying to load

then yesterday the problems ramped up; other pages start not working, not when I refresh, not when I open a new page. youtube videos will just stop loading, yahoo's inbox displays "no internet connection" warning (even when I can scroll tumblr, but the links still break) I can access those same pages and others normally in other browsers

also if I just keep working in the still half broken pages it gets to a point firefox simply stops allowing me to do anything on new tabs, it gets slower and slower, taking up to a minute to open one page (internet fine in other browsers). eternally frozen in loading pages do not allow me to access settings or react to pressing Alt, or pressing "stop loading"

I tried deactivating all extensions, I tried (and am currently writing this in troubleshoot mode) it still happens

if I restart firefox it works for a bit, and then starts breaking, timing seems rather random, (once it happened with one youtube video and one mail tab open, other time's i've opened several youtube videos a couple tumblr pages and one mail tabs (easiest to notice the "no internet connection in the mail tab)

hope this info helps

Hello,

I'm seeking support to try to resolve an issue that has recently started happening. I can't be the only one who is experiencing this, so if this is resolved others can benefit too. I'm not a complete novice, but neither do I claim to be an I.T. expert.

I use my ISP's webmail service to access my emails. I'm aware I could use an email client, but I prefer to access via a web browser and have done so for many years. About a week ago, I was no longer able to sign in to my webmail. I thought it may be a problem with my provider, so I checked using other web browsers - Safari on iOS which worked and Microsoft Edge (using the same internet connection, same desktop PC) which also worked and continues to work without issue. I can only think it must be something wrong with Firefox? I can access the sign in page as normal using Firefox and select my email address, but after attempting to login I always get the same error message:

Sorry, we can't sign you in just now

Don't worry, it's just a quick pause to help keep your account safe.

Instead:

   Use a device you've signed in on before
   Try again from a familiar connection
   If you're on a VPN, switch it off and have another go 

Still stuck? If this keeps happening, get in touch with us (quoting reference IDF-12B) and we'll help sort it.

I have 2 extensions installed in Firefox - Adblock Plus and Ghostery. I have already added the specific URLs to the allowed websites list (first is the sign in page, second is what it redirects to):

mail2.virginmedia.com oauth.virginmediao2.co.uk

I have searched around for possible solutions, to no avail. Virgin Media advise only signing in on their main home page, but I've never done this as its just another step and extra unnecessary clicks. I don’t want to constantly be bombarded with news, offers and promotions every time I want to check my email, so I only use the direct webmail sign in.

I have tried clearing cache, cookies, etc. Then I tried to refresh Firefox, none of which worked. I also tried uninstalling Firefox, then using CCleaner to perform a clean up and registry scan to fix any possible issues, followed by a clean installation. To my surprise, I was able to sign in to webmail OK. However, the next morning, I got the same error. The only other settings I have tried tweaking is adding exceptions to turn off "Enhanced Tracking Protection" and "Block pop-ups and third-part redirects" on those 2 web addresses.

Any suggestions or options to try would be appreciated.

Dozens of reboots every day due to video seizures only with Firefox. Tab crashes causes those I am ordered to support to LOSE WORK. After a tab crash and restore the FF interface is frozen -- no type of input from peripherals possible. This is all supposed to be solved by Monday. If I am out of luck with FF -- just tell me. That's very simple. New machines, new OS and it's worse than under the legacy systems we support after moving up from Win 7 Pro.
