Cleans web pages of all unnecessary visual elements, retains only the essential content: text, illustrations and images; layout and typography are customizable. In addition, this tool manages a bibliographic database, a persistent offline annotation.

Features & Capabilities

NOTE for Firefox mobile : As of today, you will be able to install any extension listed on addons.mozilla.org in Firefox Nightly ONLY. To that end, follow this procedure https://blog.mozilla.org/addons/2020/09/29/expanded-extension-support-in-firefox-for-android-nightly/


Besides rendering a reader mode, this tool can also persistently store data:

Two kinds of data are implemented: notes (collection named 'publist') and the rendered page with/without highlighted notes (collection named 'offlinepages'):

Proceed as follow: - 'publist': select some text (this will be transformed as an annotation), click the 'publist' icon, fill the predfined entries or add your owns tags. ++Most of the entries are editable on the fly at various step.

Also authors or tags must be separated by a comma (this will allow a search by author or tag)
++To allow some rich output, each "author" may be rewritten like this:	author<url@location> where location is a an address or something else

'publist' notes may be exported as json|csv|html file or import some data (csv file) to that collection.

++Using this tool on a page already saved in 'offlinepages' collection will reload its annotations too, provided urls are exactly the same.

       Save your offlinepage when you are finished with notes;

User Reviews

Beautiful and efficient! I cannot imagine reading an online article without this add-on. Once you click on this extension, all the rubbish from the web page miraculously disappears. You only have a beautifully formatted text for easy reading. No doubt, this add-on is a winner. However, the only problem is that it was updated 6 years ago. However, I don't care so much about it as long as it works. I hope that the developer is still alive. If yes, cheers, mate! 🍻
