[Question] Is this web extension respect privacy if I use it in Tor-Browser???

[amalgame21]

I noticed that the 'cli' version it has a --browser-args flag which seems can be used to specify socks5 proxy in tor.

Is using this plugin in Tor-Browser automatically do it?

Also, if I use it in Tor-Browser, will it leak some of the anonymous information to the internet?

Thanks

From my point of view, it should be fine to use SingleFile in Tor-Browser regarding the proxy issue. If an extension was able to circumvent the proxy without doing it on purpose, that would be a bug in Tor-Browser.
SingleFile can be detected. As far as I know, only this information can leak on the websites you are browsing. It means that a website (or an embedded third-party resource like an ad) might be able to detect that you used SingleFile to save a page on that site and when you did it. It would have to be done on purpose though. So far, I have never heard of this kind of "attack", which remains quite minor IMHO.

Thanks for your answer!
Since you mentioned they might be able to detect I use SingleFile, I am wondering if I just enable the extension and do not save the page by pressing the button, are they still have a chance to detect it?
If yes, I may just keep the extension disable before using it.

Unfortunately yes, because of some limitations in the Web Extension API. For example, this code will display a log in the console if SingleFile is simply enabled:

addEventListener("single-file-new-font-face", () => console.log("SingleFile detected"));
new FontFace("", "");

Of course, disabling SingleFile fortunately fixes this problem.
