Same error as in #27291 (moved) but on debian buster 32bit instead of Windows.

Appears opening new tabs:

JavaScript error: chrome://global/content/browser-child.js, line 359: NS_ERROR_NOT_AVAILABLE: Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIWebNavigation.loadURIWithOptions]

Did not see it in the Browser Console of ff 60.2.0esr. There i only see

[NoScript] Cannot collect noscript activity data Error: Could not establish connection. Receiving end does not exist. Stack trace: send@moz-extension://cbbb5823-ce8f-4641-9fbe-7172852975b4/lib/Messages.js:43:22 Could not establish connection.
