You can't the .net code runs serverside and starts a client side process.

the code i write above is generated by windows application(c#) and need to open the browser as i said above

In that case you need to get the active window of the current Firefox/browser process and target that with the new location.

Your code is doing what it says, and starting a new process.

i need to open the new location in the active window in the same tab or same active tab...the code above every time i called generate new tab...i need one tab only for this code ..every time i called open location on active tab not new tab

Opening a new tab IS the firefox default action for links or actions that would normally open a new window or a new browser instance.

You will need to find some method of getting the active tab from the Firefox process, which may of course NOT be an exposed method to avoid possible exploits/hijacking.

in this time i'm not thinking about exploits/hijacking but i need this method to solve my problem.

YOU may not be!

BUT the developers of Firefox were (are) when they decided what methods should be exposed. Their intention was to make their browser secure from third party hijacking, so some methods are not public

It may be that you will have to write an extension (javascript) that the end user can install as a communication interface between the browser and your application.

and this javascript were i will apply.
