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?

Hello,

I used unsigned extension at Firefox ESR, according to the this page: https://support.mozilla.org/en-US/kb/add-on-signing-in-firefox I toggled the setting about signature to false. At the previous revision (I don't know the exact revision, but it might be this year), it works well and an unsigned extension was installed well.

I updated the browser and re-installed the unsigned extension to update. To install the unsigned extension, i tried to drag-and-drop the .zip file (extension) at 'about:addon', but error occurs, saying "이 부가 기능은 손상된 것 같으므로 설치할 수 없습니다." (I think, this is translation of the following:"This add-on could not be installed because it appears to be corrupt.") So I added the unsigned extension through 'about:debugging#/runtime/this-firefox'. Then the unsigned extension is installed, but it is deleted when I close firefox.

Could you let me know how to install the unsigned extension?

My extension is enabled but site data permissions for its target websites are turned off by default for some users.

This causes the extension to silently do nothing on those sites until the user manually grants permissions..

I would like to allow or block extension for certain site.

What i need is: 1) Turn on extension on specific sites (like for government) 2) Do not load extension on specific sites

So there should be Order Allow,Deny and reverse Order Deny,Allow And two rules Deny *://example.com/* Allow *://example.com/some/*
