Needed: a Firefox extension/script to filter out unwanted content (all GET requests including those done through redirects: documents, scripts, iframes, pictures, any MIME type, actually).
Already checked out Schuzak's SilentBlock - not really working, cumbersome editing without a GUI.
- Open source
- No 'dial home' features
- Reliable work under Linux and Android
- A simple GUI allowing adding new/editing existing regex'es in the browser
- A list of sample regexes to filter out common ads.
- Whitelist regexes.
- Ability to fire certain blacklist/whitelist regexes based on the main document's address (e.g. allowing Google APIs on one site and disallowing it on others).
Note: ideally, the extension should prevent the browser from accessing the blocked resource.
