I remember it was a basic feature in firefox. I never understood why they removed it. Thank you for bring it back. Would be nice to have back also the option in bookmarks to open a link by default in sidebar (could you make it? maybe using bookmark tags? when you tag it "sidebar", you open this way?)

Thank you for the great job!

works exactly as expected. Perfectly minimal

I there a way to prevent links from other domains to open in a new tab so I can fluently navigate always inside the sidebar?

fuckin love this extension. extremely useful for some stuff, haven't had a complaint yet. Insane how few downloads it has.

How to make side panel resizable:
Updated instructions for Feb 2024 (I'm on Firefox version 123)

- Go to about:support
- in Application Basics section find row called Profile Directory, click on Open Directory button
- Close all firefox running instances
- In that folder, find xulstore.json and open it with a text editor
- Find where it says "sidebar-box":{
- inside those brackets look for "style":
- inside this find width: and replace with the following:
width: 50%; max-width: none !important; min-width: 0px !important;

- if you did it correctly it should look like this: "style":"-moz-box-ordinal-group: 3; order: 1; width: 50%; max-width: none !important; min-width: 0px !important;","checked":"true"

- save the file and close, open Firefox and enjoy!

wish i knew about this 4 years ago, id love it to get merged with the main app its very good

Thank you for the development of this add-on on Friefox. It's handy. Besides, is it possible to allow user to save shortcuts and open website directly in Sidebar? Thank you.

[Feature Request] Add also search highlighted text search on sidebar(maybe by the default search engine?)? That would be very convenient.
