I very often bookmark pages in Firefox in a 'Read later' folder.
This takes 3 actions:
- Hit Ctrl-D
- Pull open the Folder dropdown containing the last folders used
- Click on the 'Read later' folder
This assumes that the 'Read later' folder is in the last five folders used. If not, I have a lot more browsing to do.
I would love a (free) add-on that lets me save a bookmark to a pre-defined folder with one key combination.
