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.

How do I escalate the presence of a malicious extension for removal from the store?

[Coupongogo: Automatic Coupons & Cashback](https://addons.mozilla.org/en-US/firefox/addon/coupongogo-automatic-coupons/) is a malicious extension programed with a command and control server located in China.

Despite [Firefox user reports](https://www.reddit.com/r/firefox/comments/1pl0u6m/malicious_addon_does_not_get_taken_down/), the extension remains available on the Mozilla addon store.

A [rastersec.com contributor explains](https://www.rastersec.com/blog/coupongogo-cryptostealer),

>\[Coupongogo\] operates as a remote-controlled time bomb, utilizing a dynamic configuration system to evade detection, hijack all search and browsing traffic, and wait for a server command to activate its dormant theft capabilities targeting major cryptocurrency exchanges.

Given the lack of success at securing the privacy and security of users by using the standard addon reporting tool, how can I escalate this matter to a responsible Mozilla party for triage?

I have no idea where the ad blocker is here on Firefox and cannot turn it off when I need to. It is crazy that it is so difficult to find AD BLOCKER - I find articles that say how to do it but they make no sense because I try to follow and it still does not work. I need to know how to turn off the ad blocker - especially when I want to use Rakuten - I cannot never use it because I cannot manage my ad blocker when I need to

Hi! I've tried everything, from refreshing to troubleshoot mode, but it says the same thing, that every installation I try has been adborted due to it being corrupt. It even deleted my previous theme. I'm very stressed, could someone please help? I use Nobara Linux and will include screenshots of the following: My browser is also completely up to date, I just reinstalled. I also followed the guide it said for this issue and deleted extensions.json but couldn't find the others.

It also disappears when I download extensions after verifying and when I click to install again the button won't move before going to the actual add-ons area. Thanks!

Recently, LastPass has been sending me messages that it's no longer supporting browsing through Firefox. Is there a new extension I can add? The notes suggest switching to Safari, but I prefer Firefox. What is the reality here? Do I really need to switch or give up LastPass. I value both and don't want to have to quit either. Thanks!
