After every restart, all passwords are gone and I have to re-import them from a file. What's that about? It happens after every Firefox update. So I have to quit Firefox and reinstall it.

Mozilla Firefox. I had to upgrade on my Wi-Fi box to connect to my TV and it says that my browser is not communicating with the Wi-Fi box and I needed to communicate in order to activate the TV. The box is fine if someone could please tell me how or show me how to enable the browser in Mozilla Firefox so I can do this I would really appreciate it. It's been 3 days and I've been trying to get this to work but it's not working and it's also a 50-in Roku TV but roku's website is out and I can't get an activation code from them so I don't know what to do. But I would like for this problem to be solved

Since a few days, Firefox started crashing each time I receive a notification.

For example, with this notifications test website: https://www.bennish.net/web-notifications.html

Each time I click on the "Show" button to display a notification, Firefox becomes completely unresponsive: the content of the window is completely frozen and I can't click on anything. I must close it and restart it to make it work again. When I restart it, a dialog displays:

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

In both applications, the notification is never shown: the freeze occurs before.

I tried the following changes but they did not stop the issue from occuring:

- Deactivating hardware acceleration - Troubleshooting mode - Deactivating firefox notifications in Windows - Deactivating `alerts.useSystemBackend` and `alerts.useSystemBackend.windows.notificationserver.enabled` in `about:config`

At the same time, I noticed that Thunderbird (v144.0.1, 64bits) started having the same issue. It haappens each time I receive a new message in the background and a notification should appear. Maybe this is related?

Hello,

I have a problem with YouTube videos not playing on any website when using Mozilla Firefox. Whenever a site (like zamunda.net or other forums) embeds a YouTube video, I get the following message:

“Error 153 – video player configuration error” or sometimes “For your protection, this page will not allow Firefox to display the embedded content. To view this page, you must open it in a new window.”

If I open the same video directly on YouTube (youtube.com), it plays fine. This issue happens on all websites that have embedded YouTube videos, not just one.

Windows 11 25H2

Firefox Last Version

Could this be related to codec support (H.264 / MSE) or a security restriction with embedded frames? Any suggestions on how to fix or debug this would be appreciated.

Thank you, Panche

Good morning,

Mozilla has installed a kelkoo web app as a shortcut in windows start menu without my permission. I don't see any Kelkoo app installed in windows "Control Panel > Programs > Programs and Features" or in "Start > Settings > Apps > Apps & features". So, it appears to be just a shortcut. Can i delete it?

I am using Windows 10, version 21H2 and my Mozilla version is the 144.0.2 (64-bit).

Kind regards.

I am running the latest version of Firefox, using Last Pass extension, and signing into Bank of America US website. I've done this for years. I use a FIDO device to authenticate transactions but now I am no longer able to do that. Each time the system asks me to use my device, I get an error message saying if failed (even before pressing the device) and my only way to get out is to force quit Firefox. I am able to execute the transactions successfully using Safari as my browser with Lasspass and the Fido device.

I have called the bank and they cannot see any issues on their side.

I'm working on a Macbook running Sonoma 14.7, I have firefox on autoupdate. I do not have any passphrases saved for Bank of America.

Hello, I would like my Firefox opening to be full screen automatically. Now it opens on half screen and I have to manually expand it to full page. Can you help me? Thanks

My firefox tried to install an update. It was unable to do so twice in a row (it couldn't even download an update, was stuck on 0kb). I tried to install it manually but the installer had the same problem and was stuck on nothing I then foolishly tried to install an older version that worked for the time but seems to have f-ed everything up in the long run I uninstalled firefox and tried to reinstall it. Now I simply can't open https://download.mozilla.org/?product=firefox-stub&os=win&lang=ru

Is this something connected to my country? To my pc?

And I ran the disk scan check. It found something and repaired it. My install still doesnt work

So Every time I delete bookmarks they not only come back but they come back with a few extra of the same thing, I have Sync completely off and its still doing it. Please can someone help guide me in the right direction to get this to stop, I can Leave them alone and it now just keep adding them, so i have 5 or 6 of the same bookmarks I deleted an hour ago, a few days later it will add 2 more.

Thank you in advance!

The launch of Firefox Profiles seems to have obliterated everything in my account: bookmarks, history, open tabs, and extensions are all gone completely. I have an option to import files from another browser, but not from my own past firefox. I logged into my Mozilla account, but I didn't have any other devices so I think it was still unable to recover the data? Is there anything I can do about this, or is all of my data truly gone?

First off, apologies - I don't know if this is a YouTube problem, a Steam Deck problem or a Firefox problem. I haven't been able to figure out the cause of this problem for months so I'm trying you guys because you're more responsive than YouTube has been so I'm really hoping it's a Firefox problem.

Basically since early June I've been getting "an error occurred" errors for YouTube videos of approximately an hour. Longer videos and shorter videos tend to play fine, but I get the issue with videos under ten minutes sometimes as well.

This only occurs in Firefox on my Steam Deck (SteamOS). Other browsers and other devices are fine.

I have cleared my cache, cleared cookies, disabled extensions and logged in and out of YouTube to no avail. The problem still occurs in troubleshoot mode and updating Firefox hasn't fixed it.

Would appreciate any troubleshooting tips and again, apologies if this ends up not being a Firefox problem, I just don't know what else to try at this point.

When i sort bookmarks by 'added' in the bookmark library, the most recent bookmark that shows in the list is almost two years old. However the missing bookmarks are there, but it seems i can only find a newer (than 2 years) one if i know a word that is associated with it. Is there a way to fix the bookmarks library so the last two years of my bookmarks actually display in the library?

The latest update kicked me out of all the web pages I was logged into.

For most of those pages this is a minor inconvenience. For Deviant Art this caused an existential crises. My user name includes uppercase letters. Firefox password manager saved it in all lower case for some odd reason. And to make things even more frustrating, the username and password fields do not seem to recognize the auto fill. By the time I've realized what's going on, DA has locked me out from logging in or even attempting to recover my username and password until I clear the cache for another go... which means having to do the rounds of logging back into my e-mail and other accounts. Hopefully I've fixed the user name entry in the password file...

On the one hand, yes I'm frustrated, on the other, is there some way to fix the DA log in issue?

..and can we please not log people out of webpages when the browser updates? If that's at all possible? 

Heck, I'd settle for an easy way to clear site specific cookies. And it needs to be something I'm not going to have to search for the next time I'm booted out of a finicky website.

While I do find the AI Chat option in the sidebar useful, I don't really like that, since I've opened it, it will always be open when I launch a new window.

Is there a way for the side-bar to remember it's state, so that if I close it, before closing the browser, that it won't open when I launch a new window?

If not a state recall, how about an explicit setting? It's a bit irritating to have to close the sidebar every time I want launch firefox.
