Are there any good websites for instructing how to write browser addon for IE, firefox, chrome and Safari?
Not sure whether writing there is some frameworks which can be used to write addon for all major browsers such that one sourcecode for all major browsers.
Thanks.
IE and Firefox have very different plug-in models. IE supports binary helper objects (your native code running in IE's processes). Here’s how you can build one: http://blogs.msdn.com/b/ie/archive/2008/04/04/designing-for-add-on-performance.aspx,
here’s why you should spend as little of your users’ time as possible in your code: http://blogs.msdn.com/b/ie/archive/2011/03/23/updates-to-add-on-performance-advisor.aspx

I am well into building an single page application using nodejs and the http2 module. The client end is using Polymer and is a progressive web app, with a fairly minimal index.html. I have been doing most of the development in chrome, and am reasonably happy, since this is an intranet application and I can dictate the brower.
I would like to support the ipad, albeit perhaps at lesser performance. I have to borrow my wife's if want to try anything, and I couldn't get it to work at all. I do have a mac laptop and tried accessing my (in development) site using safari on that (I also have chrome on it and that works fine). With Safari it doesn't get anywhere. In fact with the web inspector open it doesn't even appear to have loaded the basic index.html file.
I am assuming that safari doesn't support http2. I am not sure what I should do about it through. How do you gracefully fall back to something else?
Safari does support http/2. Test your site at https://www.ssllabs.com/ssltest/ and see if you've a cipher config that safari supports.
I have been developing Chrome extensions and as I have already mentioned in a question on SO, I have problems paying that starting charge witch Google asks. So I quit wasting my time developing extensions for a company that has no respect for developers and I'm starting to develop Firefox add-ons. So I'm a total newbie in this area.
First of all I have to mention that I am NOT looking for an automatic functionality/way to convert them. I have noticed that one difference between Firefox add-ons and Chrome extensions is that there is not such a thing as popup.html in Firefox (maybe I'm wrong).
How can I find other main differences so that I can convert my extensions to Firefox add-on?
Firefox addons do have a popup paneil in their SDK available to use(https://addons.mozilla.org/en-US/developers/docs/sdk/latest/modules/sdk/panel.html).
I'm developing a Firefox addon right now and I can tell you that their actual SDK and the develop environments are great, cfx to work offline or the online builder, both are powerful and easy.
Regarding the differences that you ask, besides a few structure differences and of course Chrome or Firefox specific code that is not going to work in the other platform, I think that it should be easy port an addon from one platform to another, no automatic but pretty straightforward.
I want to create a new application (which I will sell) that uses web browser control to automatically post things on the internet etc.
I did some research, and it looks like the primary choice for most people is .NET webbrowser control (via an instance of IE).
I don't want to do this because I want customers that own a Mac and Linux to be able to use my software.
With that said, are there any web browser control classes or toolkits available that can work on all OSes (e.g. something that uses Java?)
Thanks in advance!
UPDATE:
Web browser control is basically the ability for a program to act like a human and open a web browser and go to websites, fill out forms, check email (lol) etc.
Firefox, Chrome, Safari. I think virutally everything but IE works on all the OS's. Not suprising really when you think it's made by microsoft.
Selenium libraries let you create scripts (with a GUI or one of the supported languages [it has got most of the popular ones like Java, Python etc.]) for browser automation on all popular browsers (including chrome, which works on all OSes like mentioned by other answers).
I would like to use this JS plugin to use the CSS template layout :
http://code.google.com/p/css-template-layout/
But I know that it is recommended to first have a website working without JS. So, my project consist in doing a tourism website...will I lose a lot of 'potential user' if JS is required to visit my website ?
Tkx,
About 4% of my visitors don't have javascript support includes bots though, that would explain quite a few percent. There are a few classes of browser that won't run your javascript as intended:
Screen readers/accessible browsers (like for blind people)
Mobile browsers
Console-based browsers (Used sometimes by sysadmins from servers with no gui installed)
Off-brand browsers or older browsers with buggy javascript engines
Search Engines (Google)
I don't think that many people just turn javascript off anymore. However, things like NoScript --where javascript is disabled for a site initially and must be explicitly enabled-- are becoming more popular.
The problem is more apparent on mobile browsers, but you will likely serve different content to them anyway.
What technologies are used to power Quake Live?
Specifically, how do you create a web application that makes such extensive use of 3D in the browser? The service requires you to download and install a plug-in in order to play. How do you create such a plug-in, and how does it interact with the web site?
Browser programs are very simply, programs. They are given an interface to interact with the browser, but beyond that, they can do anything a normal native application can do, like use DirectX or OpenGL.
Internet Explorer registers plugins using ActiveX. Firefox, Chrome, Safari and most other browsers use Netscape's NSPlugin API.
The MDC has plenty of documentation on writing plugins for Firefox.
There is also a question on SO about writing plugins for IE.
