SelectionSK

SelectionSK is an extension which automatically pops up user menu with useful tools (copy, search, translation, etc.) when text is selected with the mouse.
The idea beyond the extension is that text is always selected with the purpose, so it is more convenient to automatically popup the menu on selection rather than do it in two steps (select and right mouse click).
It's easy and extremely convenient. Give it a try!
Note: WebExtensions API doesn't provide access to search engines, so during initialization addon will create 'SelectionSK' bookmark folder under 'Other Bookmarks' and populate it with search and translation urls. Please modify this folder according to your needs.

Functions:

Copy selection to the clipboard in various ways (standard copy, copy as plain text, copy as html). In addition, selection can be copied to clipboard automatically.
Send selected text to pre-configured bookmark urls. There are default search\translate\dictionary urls, in addition you can create your own.
Phrase search supported by using right mouse button, see support site for details.
Open text as URL. Text will be validating for URL in a smart way – in addition to well-formed URLs, extension will check broken URLs (for instance, without http prefix) and href attribute. Obfuscated URLs and email addresses like "hxxp://website(dot)name(dot)com" or "mail(at)provider(dot)com" will be detected and de-obfuscated.
Highlight all occurrences of the selected text.
Panel mode: small panel with icons only will appear instead of popup menu.
Send selection to the mail recipient. New email window will be opened using mailto: protocol, selected text will be added as email body. In addition, selection will be copied to the clipboard, which allows to insert it to the email from the clipboard (useful if selection has images or rich html).
Toolbar icons provides a shortcuts to enable\disable addon or to preferences.
