Once the user clicks an anchor tag I need to open a page in Firefox.
Example:
<!-- Currently the anchor tag is displaying in any of following browsers:
Internet Explorer, Opera, Safari, and Chrome -->
<a href="sample.html">Sample link to open in Firefox</a>
Once the user clicks the link, I need to open file sample.html in Firefox. Impossible is nothing. But I don’t know how to do this.
Is there is an option to do this in JavaScript, jQuery, or PHP?
You cannot, from a given web-page, specify in which software a link should be opened.
At best, if your anchor points to a specific kind of file (like a .doc), the system will know that it must use some other software than the browser (like MS Word — or ask the user which software he wants to use). But, for an HTML page, the browser will be used.
And your website has no control over this.
