two excellent functions:
1. short cut
2. custom format
Therefore I can quickly copy url into emacs.

Works for multiple selected tabs!
However, you have to enable that under Manage Extension > Extended mode (beta) > Enable multiple selection tabs.
toshi, please enable this major feature by default. It's the primary reason I went for this extension, is advertised as being supported (but isn't really by default and without instructions of how to enable) and is it's major benefit over others, and is very hidden in non-intuitive location. Thanks for such an excellent extension!

Perfect - couldn't be any better...

Functional. This extension can put the URL, title, or both into the clipboard for a single tab, all tabs in the current window, or all tabs in all windows.

This extension does not support multiple selected tabs (introduced in Firefox 64).

Thank you so much!

Work's fine but it will be better if it execute action without opening new tab

please add empty lines in "Copy the title and URL of all tabs" between lists, because each list composed of 2 lines.

Could you add a tooltip that shows the URL when you hover over the tab?

能支持多个自定义格式吗？如 “格式1”，“格式2” 这样。

Simple, very useful. Thanks toshi !

Perfect. The best one so far.

Few recommendations:
• add an optional checkbox to insert a newline between title and url of each tab (for both Current Window and All Windows). This just makes reading more pleasant.

• try to have two quick access click buttons so users can set
1 button for Current window's title and URL of all tabs OR
1 button for All windows' title and URL of all tabs OR
1 button for any customized style.
This can be handy because users do not have to go through the context menu, and then select an item--- which requires 2 clicks, and efforts to navigate on the right menu items.
Try not to use keybindings because that may conflict with other programs. Or, if you will do that, please leave that as an optional checkbox.

• the "format" option is somewhat confusing for the first time user. It should be called something like Customized style or Customized format, and should be grouped into the 1-click button as an option.

• the format does not allow a user to insert a newline between title and url (if you do have this feature, please provide a side note something like the ${\n} or \n so that we can use this customized format:
${title}${url}\n

• a great add-on deserves a great icon.

Good work. Keep it up.
Yours truly,
