Not exactly the same but as a fellow Firefox user here is one of my workflows (some practical stuff at the end):
- research one topic, using a Firefox instance with Tree Style Tabs, ctrl clicking each link I follow thereby opening it in a new leaf-branch, producing a tree of tabs documenting where I have been.
- research another topic... and another and then a few more.
- realizing after a few days I have more than 600 tabs open just in my research browser (I have one reserved for customer systems and mail, and on that I use mostly only Bitwarden, uBlock Origin and container tabs).
- I select one or more trees from my research browser, export them to markdown and get a nice indented markdown list of everything, copy those into Joplin, go back to Firefox and right click to close all selected tabs.
- that's it.
Hints: For this to work you need Firefox, the Tree Style Tabs (TST) Firefox extension as well as one or two TST extensions. Yes, on Firefox extensions can have extensions, and no, it doesn't bog down my browsers to any significant degree. The relevant TST extensions can be found linked from the TST addon page, yes they are also Firefox extensions but they won't help much without TST I think.
