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?

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.

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?

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 have an old credit card somewhere in the firefox memory that I want to delete, where is it located and I will need step by step instructions (WIN 11) to find it and delete it so it stops showing up as a payment option.

There used to be dozens of video downloaders. Now, none of them work except for one that requires a ridiculous fee. Are there still youtube video downloaders that still work

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.

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?

Audio doesn't work with Firefox. This appears to be ONLY a Firefox problem. Headphones work with Edge. Computer speakers work. In Windows settings, testing audio works. But when I attempt to listen to something in Firefox, there is no sound at all.
