Help and fixes

• No Block channel button
• Extension switched off
• Lists not saving
• Forgotten PIN
• Where it works

The Block channel button is missing, or videos still show

YouTube builds its pages bit by bit and changes the layout every so often. A tab that was open before you installed or updated the extension, or right after a YouTube update, may not be connected yet.

1. Reload the YouTube tab: Ctrl+R, or Cmd+R on a Mac.
2. Check the address. Channel and word filters run on www.youtube.com, not on m.youtube.com, music.youtube.com or YouTube Kids.
3. Open the panel from the red icon and check that the main switch at the top is on, along with the feature you expect.
4. If one kind of card keeps getting through, write to info@blockchannel.one and say where it was (Home, search, Up next, Subscriptions). We'll fix it in the next version.

The extension switched itself off

Browsers sometimes turn off extensions loaded in developer mode, for example after a click on Disable in the developer mode warning, or when the folder was moved or renamed.

1. Open chrome://extensions (or edge://extensions, brave://extensions, opera://extensions).
2. Find Block YouTube Channels and switch it back on. If it complains about missing files, the folder has moved: put it back, or load it again with Load unpacked as on the install page.
3. Reload your YouTube tabs.

New channels or words don't stick

Your lists live in the browser's sync storage, and the browser caps how much it holds. When the cap is reached the extension moves to storage on this computer only. The lists keep working there, they just stop syncing between computers.

• Clear out channels and words you don't need any more, long phrases first.
• Use Export in the settings to save your lists as a file, and Import to bring them to another computer.
• Added something on another computer a moment ago? Give browser sync a minute, then reload YouTube.

I forgot my PIN

The PIN guards the settings, and nobody can recover it for you. Only a scrambled version is stored, in your browser, and we never receive it. Starting over means resetting the extension:

1. On the extensions page press Remove on the extension.
2. Load the folder again with Load unpacked. It starts with empty lists and no PIN.

If the old PIN comes back, browser sync restored your old settings. Turn off syncing of extensions in the browser's sync settings, do the two steps again, then turn sync back on. Resetting also clears your channels and words, so import your exported file afterwards if you have one.
