I wish to disable support for JavaScript embedded in HTML-formatted emails in Thunderbird. What is the recommended way of doing this?
In case no one else has this issue, I've been using Thunderbird since the elder days, when it was called Netscape Mail & Newsgroups, and upgrading it all this time; I think JavaScript in email may have been enabled by default way back then.
I found the about:config
screen from the Advanced tab in Preferences. There's a very obvious-looking option called javascript.enabled
currently set to true
. Does this option control running embedded JavaScript in email, and nothing else? In other words, if I disable it, will embedded JavaScript not run, and/or will certain Thunderbird features suddenly stop working? (I'm afraid to try it, because for all I know, the about:config
screen is implemented in JavaScript, and there might be no way to return to the screen if I turn it off.)
