Diễn đàn hỗ trợ Firefox

After I use a cleaning tool to clean out cookies and activity and whatnot. (I'm using 'Wise Disk Cleaner') I am no longer logged into my mozilla account. (which is expected)

This is where my trouble begins. When click the profile icon and click 'Account disconnected' I am taken to a settings panel with "You are signed out of {my account} There is a shortcut there that take me to accounts.firefox.com and I am greeted with a flashing infinite loop that says "Local storage and cookies are required"

I end up having to go to the "Settings/Privacy and Security" and clear all my browsing data and cookies. Then I can try to login and the actual login screen appears

My second issue is... this login screen seems to be specifically designed to prevent password managers. Once there I need to enter my code for 2ndfactor...

All this to say... is there an easier solution? Normally I just click 'login', swipe my finger on my finger print reader and my password manager enters the information and I am logged in.

(And all this just so I can sync a few dozen bookmarks)

I can't download some pdfs, notably my bank statements. I CAN download some pdfs. Eg, I can download my car manual (although it's a process of downloading it to my Google Drive). However, trying to download my bank statements, Firefox gives me no options at all, and, indeed, I get an error message. Yet I CAN download my bank statements using Google Chrome! I've carefully checked all my Firefox settings, but nothing seems to address this problem. I've spoken to my bank, and they don't know why I can't download them either. When I try to download the statements, I get a screen saying it can't give me a 'Preview' (see attached screenshot), but there's a 'Download button. When I click that I get a white screen with the 'error' message:

"No API key found in request. request_id: d52e0732a3d10a75b1ec58534845c15c"

(2nd attached screenshot.)

I have asked about this before on this forum, but to no avail.

On two different Windows machines, current Firefox (153.0.1), the alt-d shortcut stops working: it does nothing until I restart Firefox. Then it works again for a while. I've tried about:keyboard and it's not reset there. I tried all combinations: Clear, Reset, setting it to alt-d explicitly. None of those worked. But when I set it to alt-a, that worked--but then resetting back to alt-d again didn't work. That shortcut is muscle memory at this point, so it's quite distressing. Not sure what diagnostics might be available to help here, happy to try anything.

Full disclosure: Both machines are Windows 10 but since that's stable, I find it hard to believe that's related.

I have completely cleared relevant history. I am in the UK, so only use Amazon UK. Yet, even within a day of removing all trace of amazon.com, it shows up again in the list of top sites on a blank tab's address bar suggestions. (.com is not in bookmarks, shortcuts, or recent searches, which are the only other selections)

The only explanation I have for this is that amazon.co.uk is making back-end calls to amazon.com and polluting whatever mechanism is used for this list – even though the browsing history as I can see and manage it does not include any references to amazon.com whatsoever.

Please, either:

• tell me how to get the browsing history as shown in the new tab's suggestions to respect the browsing history as recorded and manageable, or
• tell me how I can have control to blacklist certain sites that contaminate the list despite there being no record of them within my browsing history

The only other detail that may play into this; the first time this appeared out of nowhere I suspect was also the point at which the Suggestions from sponsors magically appeared in settings, and was on by default. Ever since then, getting rid of amazon.com has been a Sisyphean struggle, as though unchecking the sponsors option were being ignored.

Not 100% sure if the topic is the right one, but here we go - I use a Macbook with Firefox 153.0.3, UK Keyboard (QWERTY) It's about the command + ` (the key in the left upper corner below the esc key, I made the ` bold so it's easier to see)

Sometimes, but only sometimes, the keyboard shortcut command + ` to cycle through open windows in Firefox does not work.

For example, I have two windows open (W1 and W2). If I'm in W1 I can use the command and it will cycle to W2. But using the same shortcut, I can't navigate back to W1. But if I use command+ SHIFT+ ` it works. This changes from day to day, sometimes it's command +` and sometimes it's command+ shift+`

This only affects Firefox, in all other programmes, the shortcut works as it should Can't find rhyme or reason- does anyone have an idea?

Wäre es nicht Sinn voller mal Firefox so zu Optimieren das er nicht gleich 50% des Arbeitsspeicher belegt. Ich beobachte schon länger das wenn Firefox eine weile Läuft sehr viel Ram braucht. Da gibts andere Browser wie Brave die viel weniger Ram belegen als Firefox.

Könnt ihr da nicht mal ansetzten und was Optimieren Bei den Ram Preisen Aktuell kauft man sich ja kein neuen RAM.

I can not log in to home depot website because it won't send me the verification code. No other website gives me this problem and I can log in with Chrome.

How can I fix this?

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.

Hi, I was a heavy user of the multi-account containers extension. Since FF now has that functionality built in I disabled the extension recently (more than a week ago). My company keeps FF up to date - currently on 153.0.3 aarch64

All tests have been performed with other extensions (ublock origin and auto-reader view) disabled.

Since the last update (last wednesday I think, 5th. Aug.) I've been unable to access the AWS or Azure portals from a container tab, though it works correctly from the 'bare' browser.

I've cleared cookies and site data for the whole browser (made no difference)

I've cleared cookies and site data for the container tab - this now allows me to sign into Azure (which is a prerequisite to signing into AWS), but AWS is still blocked with a microsoft message "We cannot sign you in, try a different user name"

If I use the bare browser, no container, I can sign into the AWS SSO portal correctly.

What can I check to help diagnose this? MacOS Tahoe 26.6.1 Firefox 153.0.3

regards

Chris

Hello, I've been using Firefox for years, but last couple months or so - it's been losing Internet connection - I have to stop and restart it and all ok - somtimes for 5 mins - sometimes for 15 or so - but it's doing my head in :) Any help appreciated - Thanks

I want to make the switch from Chrome to FF (to continue using UBO), and a problem I keep running into is media not displaying in Twitter(X)'s DMs while using Private Browsing mode. It only comes up as a gray block that says "Failed to Load" with "Retry" under it, but it never loads. It also asks that I re-enter my DM password every time the page reloads.

Everything works fine in a regular browser tab, the issues only occur in Private Browsing.

I have tried disabling UBO, disabling Enhanced Tracking Protection, and clicking the little shield icon in the URL and turning that off, too. Looking this up really didn't give me any results that actually helped, either.

Help would be much appreciated! This really is the last big hang-up I have to not switch.

Hi. Every time I go into youtube, the sound cuts out after about an hour. I then have to go to settings, volume mixer and Mozilla Firefox and click on the X to get the sound back. Youtube has assured me this is not their problem, but a Mozilla one. I've been with Firefox for many many years and have never had this problem. Could you please advise me as to what to do about this ? Thank you.

Hello, i recently upgraded from a 4k monitor to a dual 4k ultrawide monitor, and have been having visual issues specifically on firefox and no other applications. when firefox is out of focus and i have a different window selected, the text in the firefox window becomes blurry

It seems to be related to video playback but not sure. It was happening while a video was playing full screen, and also after stopping playing/hiding a non-full-screen video.

To catch the issue had to screen record at 240fps. I used Nvidia Overlay to record the issue, but was happening before the overlay was even enabled.

Disabled all addons, made no difference. HW acceleration on or off, still happened.

I tried turning on logs, and this always seemed to show up with the flash: ``` 2026-08-09 06:19:44.048000 UTC - [Parent 8388: Main Thread]: D/Widget GetWorkspaceId - calling AsyncUpdateWorkspaceID() 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget calling GetWindowDesktopId 2026-08-09 06:19:44.048000 UTC - [Parent 8388: Main Thread]: D/Widget GetWorkspaceId - calling AsyncUpdateWorkspaceID() 2026-08-09 06:19:44.048000 UTC - [Parent 8388: Main Thread]: D/Widget GetWorkspaceId - calling AsyncUpdateWorkspaceID() 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget called GetWindowDesktopId, hr=00000000 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget calling GetWindowDesktopId 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget called GetWindowDesktopId, hr=00000000 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget calling GetWindowDesktopId 2026-08-09 06:19:44.048000 UTC - [Parent 8388: BackgroundThreadPool #276]: D/Widget called GetWindowDesktopId, hr=00000000 ```
