I love it!

Especially for copying whole trees of tabs from treestyletabs into my todo lists, to keep them from living in my browser.

Works extremely well, thank you.

Piro has made yet another amazing addon-on for Firefox! Tree Style Tabs is the #1 reason I'm still using Firefox instead of Chrome. There is NO good similar add-on for Chrome.

This addon will copy TST's structure as Markdown list which lets you paste directly into a Mindmap application which is GREAT for using Mindmaps as bookmarks.

20220822Mon Update:
For about a month now it's been badly interacting with Firefox and Windows AV to cause prolong freezing of all FF windows upon copying either URL or URL+TITLE. There is another less popular plug in that only freezes for an instant. This one has been taking a loooooong time - over 5 minutes if the free Memory is running low, requiring a restart of FF. I'm happy I found the culprit. Now I hope the coder can find and resolve.

I've used the Kung Fu out of this thing for a year or two and I missed it. Ah foun u!

It is able to copy Tree Style Tabs tab's structure (Markdown list) ! Great addon thx!

Great addon. Could you please provide us with the source code? I would like to see how its programmed. EDIT: Nevermind, I found it. https://github.com/piroor/copy-selected-tabs-to-clipboard

Is there a possibility to use a "hard (carriage) return" instead of the EOL (End Of Line) character? When I paste Title+URL in LibreOffice this would be handy regarding formatting of the pasted text. Thanks!

This used to be part of Multiple Tab Handler which was not only programmed to allow multiple tab selections, but had directions for other extensions to be able to tie into it for functionality.

Now that Firefox itself and other browsers can select multiple tabs, it is obvious that this addon is specifically for copying information from the tabs Title and Url along with Metadata such as Description and Author for each selected Tab. Wished I had noticed the %RT% years before which means it can be pasted into RTF areas as well as Text areas. Don't forget the config setting. This definition was and still is one my favorites (and now that I know about the %RT% so much the better)

can't paste code, but
HTML Link with &Desc [LI]

would include target="_blank" and href="%URL_HTML%" and title="%DESC_HTML%" within the anchor, then enclosed within list (LI and /LI) then followed by %RT%

Firefox extensions make more use of context menus, and this one is no exception. No need to have the addon icon on the toolbar. Will just be using the tab context menu and because of that having 21 or more patterns to choose from is not a problem. 5 STARS.

ty, very useful!
feature request: keyboard shortcut:
current workaround:
1. In about:addons, extensions, Copy Selected Tabs to Clipboard, Options, Enable : "Show context menu item in the context menu on the content area"
2. use ahk to make a hotkey: (this is for urls)
$^+c:: ; {ctrl} + {shift} + c
Send, +{f10} ; send {shit} + {f10}
sleep, 50 ;wait 50 miliseconds
send, yl
return
