I suggest creating a new bookmark folder and store such links in it.

Hi rjk, I'm not sure what you are saving. ''<p>RJK7 [[#question-1287160|said]]</p>'' <blockquote> I need to save many '''shortcuts''' for medical research. The ability of saving numerous '''single files in a folder''' is absolutely essential to my work. ... Saving to '''a hidden sidebar''' is not the answer and not a helpful solution. </blockquote> I can think of two things: '''''Bookmarks''''' You can bookmark a page to any folder, and as many as you like in a single folder. You do not need to create new folders for each bookmark. If your Firefox is not showing the New Bookmark drop-down to let you choose a folder when you click the star or press Ctrl+d, there's a checkbox for that (info to be provided if needed), and if you want to pre-set a different default folder, there's an add-on for that. The only time I can think of that Firefox suggests creating a new folder for bookmarks is if you have selected multiple tabs or select Bookmark All Tabs (Ctrl+Shift+d). Is that the scenario: you want to create bookmarks for multiple tabs at once in an existing folder? '''''Saving Webpages to Disk''''' When you use Save Page As... => Web page, Complete Firefox creates a main HTML file and a companion folder with all the files used in the page. This is a classic approach used for decades that all browsers offer. If you want to save the page as one single file with everything rolled into it, here are a couple add-ons you could consider: * SingleFile: https://addons.mozilla.org/firefox/addon/single-file/ * Save Page WE: https://addons.mozilla.org/firefox/addon/save-page-we/
