npapi

I need to write some Google Chrome extension. The problem is that Chrome JavaScript APIs don't give me enough power - I need to use native code. I thought about writing a NPAPI plug-in that will provide the extension some custom JS APIs. Is it possible to package the extension, plus the custom NPAPI plugin inside a .crx, and then upload it to the Chrome Extensions Store ? Another issue with this method is that the NPAPI plugin will have many versions: Linux, Windows, OS X, x86, x86-64, etc. Is it possible to package all these in the crx and use the best version? Thanks. EDIT: After reading

We have written a document management system and would like to digitally sign documents using the web client. Our Java client application is already able to apply and check digital signature, but we would like to make signature even with our web client. This is written in GWT and so, when run on the client side, it is a JavaScript application. We not want to create a Java applet and download it on the client and execute it. We would like to use the browser security device or the browser API in order to sign a document. We would also like to keep the complete document server side, and move to

I'm curious as to the procedure for writing browser plugins for browsers like Chrome, Safari, and Opera. I'm thinking specifically of Windows here and would prefer working with C++. Are there any tools or tutorials that detail the process? Note : I am not referring to extensions or 'addons'. I'm referring to a plugin similar to how Flash and Adobe Reader have plugins to handle specific content-types. As others point out, plugins for those browser are written using the NPAPI . Note: Both Firefox and Chrome will default most plugins to click-to-play soon , with Chrome planning to phase out NPAPI
