How to write a plugin for the browser? Greasemonkey or native plugin?

Question

Browsers

Task: to create the most cross-browser plug-in to control visited pages.
Features:
1. allow/blocklist
2. keyword search
3. session control time (internet time)

After searching the net, I found several ways to create plugins.

Method 1: Userscripts (userscripts.org)

Description of the method: writing a Greasemonkey script, java-script code that is inserted into the browser as an application.

Supported by:

By Firefox using Greasemonkey
By IE with its own version of Greasemonkey
Natively (soon) by Google Chrome (start from v.4)
Natively by Opera
And even by Safari

As a summary, I came to the conclusion that this is a fairly optimal / economical way to write a plugin - it comes down to writing a JS script. But there may be limitations on interaction with the browser.

Method 2: writing a native plugin

There are various open-source frameworks muffin.doit.org/ , proximodo.sourceforge.net/ based on which you can write your own browser extension.

developer.mozilla.org/En/Plugins :_The_first_install_problem - also a good description of an article on how to create an extension for Gecko browsers.

This method seemed more difficult to me. I did not find any advantages, maybe I was looking in the wrong place.

Q: Are there other ways to write browser plugins? Which one is the most efficient?

Answer 1

I don't like the idea of ​​your plugin.

Answer 2

there are frameworks that allow you to write plugins / extensions for all or most browsers
