Lastpass does not log out when I close Firefox. I have no other browsers open, and have checked the box in Extension Settings, Security to Log Out when all browsers are closed. Every time I close Firefox, and relaunch it, I am already signed in to LastPass through the Firefox browser extension.

This does not happen with the Edge browser, just with Firefox. And it does not happen on my wife's laptop. We both are running Windows 11, and Windows & Firefox are both up to date.

HELP, please! This is a serious security problem, and if there is not a fix I will have to remove Firefox and use Edge.

Hi,

I’m working on a website ( https://greenleavesnursery.com/ ) and I’ve added JSON-LD structured data to improve SEO. I know Google Search Console can test it, but I want to verify directly in Firefox.

Is there a way to see if the JSON-LD is being parsed correctly in the browser? Any recommended Firefox developer tools or extensions for checking structured data or meta tags? Are there browser-specific issues I should be aware of with dynamically-injected metadata via JavaScript?

I’m trying to debug and make sure my pages work correctly across modern browsers before submitting them to search engines.

When I'm watching videos on twitch, ads are still playing even though I have ad blockers on. The blockers will work for about a day, but then the next it just doesn't block any ads anymore.

I keep getting this plug for Capital One shopping add-on. I keep rejecting it, but keeps coming back. I do have Capital One card - but not sure how connected those two are.

Let me know if you have good experience with this thing. Thanks.

Hello, I’m here to ask, how do I install extensions? I have the Firefox app downloaded but when I try to install BTRoblox, Roblox+, and etc. It shows me an “Download Firefox and get the extension”. Now, I think there’s an issue with the add-ons memory card. Because it would take me to a page of mozilla.org. And there the only thing it’s says is “Almost there! Now finish installing Firefox.” Even if I have the app downloaded, I’m on an iPad and I need multiple extensions to download. How do I fix this?

Hello!

I first installed Video Download Helper several weeks ago and it worked fine. However, since the update of 04 March, 2026, it no longer works with YouTube. (It does, however, still work with Instagram.) Having checked all of the settings (which I had/have not changed), I uninstalled it today and then re-installed it. This hasn't helped. With YouTube, the Downloader icon (pinned to toolbar) simply remains grey and does not show any videos when opened. I am using the latest, fully updated version of Firefox with Windows 10.

Can anyone help, please?

Many thanks,

Stuart.

I've been using alt+a to open new tabs in a multi account container for a long time. Recently that shortcut stopped working possibly with the update to v148 as indicated in this reddit thread.

alt+a is not listed as a shortcut in about:keyboard or in about:addons > manage extension shortcuts or in my ubuntu shortcuts nor in any software I can think of thats running. I've disabled all add-ons except multi account containers and it still does not work. Changing the shortcut to another works fine.

Why would just that shortcut stop working? What else can I do to diagnose the problem?

I can't do a review or get in contact with the developer of "Watchmarker for Youtube. I can read 145 reviews, but I can't actually write one.
