Compatibility

Content protection script successfully tested on following browsers:

• Safari
• Mozilla Firefox
• Google Chrome
• Chromium
• Yandex Browser
• Opera and IE has some issues described below.

Opera: adding link in the beggining of content not working properly. With parameter "first: true" text in Opera Browser will not be copied.

Internet Explorer: has the same issue as Opera (using first: true disabled coping proccess). Also if user clicks Ctrl+C 2 or more times it gets 2 or more additional text/link in buffer. So using "first" parameter not recommended if you audience mainly use IE browser.
