[tor-talk] "Your Firefox is out of date"

[Random User]

Thank you very much for the prompt and helpful response. One question,
concerning the instruction:

> As a workaround one can either install a new Tor
> Browser 6.0.3 version from our website or set
> `extensions.systemAddon.update.url` to `""` which should get rid of the
> out-of-date-extension the next time an extension update check gets
> performed. 

Is that  to place two quotation marks (") into the field for the URL
string?
