Mark as Read από Dallog Fheir

Mark as Read is a simple Firefox extension to mark webpages as read.

It applies CSS style to all links pointing to those webpages so that you know which ones you've already read.

Customization options include:

• CSS style for read links
• URL preprocessor JavaScript function (for example, to ignore search
  parameters in URLs)
  

All read webpages can be exported in JSON format, with exact timestamps when they were marked as read. They can also be imported back.

Needed permissions are:

• access to all websites – for the content script to apply CSS to links
• storage – to store settings
• script-src 'self' 'unsafe-eval' content security policy – to execute the URL
  preprocessor
