WebMemex v0.3.3
This extension takes a step towards turning the browser into an offline-first knowledge management tool. It can store snapshots of web pages you visit on your computer by 'freeze-drying' them: removing scripts and thus most interactive behaviour, but inlining all images and stylesheets to let you save the page exactly the way you saw it.
Usage
To store a page, press the extension's button (usually found next to the address bar). To view all pages you stored and search through them, open the overview; either from the button's popup, or by pressing Ctrl+Y (if it works on your system, shortcuts seem to be a bit flaky).
Privacy perfect
This extension is completely local, it never sends or contacts anything. Snapshotted pages are stored inside the extension (you can also save them as html files). When viewed, such a stored page does not make any connections or execute any scripts.
