Twitter x.com List Member Extractor от Zashiwaki

How to use:
1. Open your Twitter list so that you see the pop-up with "List members" title.
2. Click on the extension icon and select "Get Members"
3. Do not close the tab and wait for a few moments (depending on how many members your list has).
You can safely click out of the extension window or open something else on your computer, but the tab needs to be kept open.
4. Done :) You'll see a list of list member names and profile URLs in the extension window.
It'll stay there until you click "Clear Stored Members" or clear your browser cache.

Hope this is as useful to you, as it was for me ^_^
