Browser Extrension / Plugin - repost

I need a browser plug that will do the following: 1. I should be able to highlight a text on a webpage 2. The plugin should be a toolbar button located next to the address bar of the browser. When i click on the button, it should show a menu option that shows "Find" 3. When find is clicked, it should show a text box with the value from the highlighted text. The interface should also show find all button, when i press this button it should highlight all the instances of the highlighted text on the webpage i'm looking at. 4. If the page refreshes, it should keep the highlighted text that is in the text box of the find menu. This should be compatible for all browsers: all versions of ie, chrome, firefox, and safari. i want use html / java to create this plugin if possible. so basically when i click the find button, under the find button it should have a textbox with the value set to the whatever text i've selected in the webpage. beside find button, should be a find all button, which will highlight all instances of the text on the webpage that is currently in the textbox
