Tabs List by Violgamba

It's pretty simple. It's just a textbox filled with a list of the window's current tab urls. You can copy this list into a document, an email, etc. Alternately, you can paste a url list into this textbox to reopen the urls into new tabs.

This add-on is useful for keeping tab collections in textfiles, sending tab collections to other people and computers, using tab collections in software projects, etc.

To this end, you can work with lists using a few different styles:

• Line Separated - Each url is on it's own line: a vertical list of urls.
• JSON / JavaScript - Urls are posted as strings in a JSON array. Useful for software projects.
• Space Separated - All urls are on the same line with a space character to separate each one. Useful if newlines are not desired.

HOW TO USE:
After the addon is installed, a new icon labeled "Tabs List" is added to your Firefox browser's title bar. It's on the right side, beside any other addons (as seen in the first screenshot). Click on that icon to open the interface for working with this addon.
