Archive Page by John Navas

Adds a button to the Mozilla Firefox toolbar. When clicked, it sends the URL of the current tab to archive.today to preserve a snapshot of the page, and opens the result in a new tab.
Also includes Link context menu to Archive or Search, Page context menu to Search.
Archive URL can be bookmarked for future reference, shared, whatever. Uses HTTPS for security.
For similar functionality on Android, check out Share2Archive in the Play Store.

PRIVACY: This extension does not collect user information. It only sends a URL to archive.today in response to user command. The privacy policy of archive.today (as of this writing): Source IP is not disclosed, "but take in mind that when you archive a page, your IP is being sent to the the website you archive as though you are using a proxy (in X-Forwarded-For header). This feature allows websites (e.g shops or the sites with weather forecast) target your region, not mine."

NOTES:
1. If you get an error, try again or try later. It's NOT an extension issue—archive.today sometimes gets overwhelmed.
2. CloudFlare DNS may not resolve archive.today, so if you experience DNS errors, try a different DNS service.
