Firefox Community Forum

I got this new Chromebook, and now I'm having issues using YouTube. When I select a video to watch, a message pops up at the top saying "To play video, you may need to install the required video codecs." I am able to watch the video I selected anyhow, with some minor issues with the picture and its frames I believe, however, when I try to watch a different video, it does not work. Sometimes it will play for a short bit, but will then stop, and start buffering. When I then refresh the page, the video will not play and will only buffer. I am not sure what to do, and if this is an issue with the browser, or the device itself, please help?

There is no option to save addresses in my Autofill settings as the help article says there should be. I have signed into my Mozilla account and no difference. Credit cards working fine. What's going on?

My Firefox browser has been crashing for a while now (Years). It's fine playing YouTube and BBC iPlayer but when I advance the time marker to a different part of the stream or video, it crashes. It also has a problem when playing slots. It seems to crash a lot making it impossible to play.

I have tried using Firefox in Troubleshooting Mode but the same things happen.

Here's the crash report ID

Many thanks in anticipation and I hope someone can help me fix these issues.

I decided to download Firefox and make it my default browser, so I downloaded it and followed some recommendations I found online for configuring security settings...but for the life of me I can't remember what those are.

Weeks later, I decide to watch Peacock, but the error message says I need to disable my ad blocker. I search for an ad blocker in the extensions but can't find one, so I start disabling other extensions like Facebook Container...but to now avail. I follow all the usual online steps--clearing my cache, restarting the application, restarting my computer, etc--but nothing works. I have the same error with Netflix, and switching to another browser yields the same result. So it must be something wrong with my system.

Can you help?

When typing in my email address, Firefox automatically completes the name. My name was mispelled once and now it appears every day. How do I delete this?

Thank you.

This is an exact copy of a question with the same title by Steve Ediger, of August 2022, now archived.

Firefox has my credit card information and it shows up in a window when I go to pay for something, but when I click on the credit card I want to pay with, the details appear on the form but get removed almost instantly.

I am in UK. It was working until recently.

None of the earlier answers have helped.

I went to a new website it asked me to put in an email address, Upon starting to type I saw I had 10 or 11 things to choose from. I want to edit these out one by one, is there a procedure to do that? Thank you.

I have tried to set this up and have filled in and saved details for two credit cards using Firefox.

When I access the payment screen for payment - (in this case for VTTA membership) and click on the credit card number I can see a hover screen with ****1234 or ***5678 indicating my saved cards. When I press return for either card no details are filled in. When I key in the details manually for either card I get a red highlight for all fields and the payment is not processed. Does anyone know what I may have done to cause this?

I would like to be able to restrict autofill of my name, address, phone number, ect to only (1 or 2) certain websites. I don't want it to be available for all other websites. Can this be done?

When I try and log into a website (lets take a signup page for example) FF will offer me a dropdown of my common usernames and emails, but also the email of my wife.

The thing is, in the privacy settings, there is not username section, only passwords and within that list her email doesn't come up once.

I have no idea how to remove this autofill but there are a bunch of old emails and usernames etc in there that are just in the way and I'd like to get rid of. Anyone any idea how to fix?
