Failed to launch Tamper

Which sites? Maybe it's due to another Chrome Extension. See #199 for example.

Yes, chrome.google.com is not allowed to have chrome extensions :-(

Like youtube.com. I've read that related issue, but I can't identify which extension has an enterprise policy.

Workaround

Browse to chrome://policy, see which extensions have enterprise policies, uninstall them (GNOME Shell integration in my case), finally restarting Chrome. It should be working!

UPDATE:

If the extension cannot be disabled or removed, then you have to delete the extensions folder in the Chrome profile.
Usually, it's on (to make sure, check your profile path at chrome://version):

$HOME/.config/google-chrome/Default/Extensions/:extension-id
$HOME/.config/google-chrome/Default/Local\ Extension\ Settings/:extension-id
$HOME/.config/google-chrome/Default/Sync\ Extension\ Settings/:extension-id
