Answer 3

Deprecated means that the object or method is put of date/old fashioned/or dangerous to implement and there is a good alternative available. Simply type the deprecation warning in google and you will get the things to get .

If you are using an external library then go to their website or forum and ask or search this

Answer 4

Offhand I believe the message you mention is technically a warning not an error. This should be gone in an update.

Even the newest versions of Firefox show it, even tho it shouldn't be shown as an error more as a warning.
