How can one allow XSS in local HTML files?
I have two files on my computer, in the same folder. Let's say that they are "PageOne.html" and "PageTwo.html". Now, PageOne has an IFrame which contains PageTwo. I want PageTwo to be able to access something from PageOne using Javascript, but XSS security in Firefox prevents me from doing that. I want my local project to stay local, but I also want to find a way to securely have both HTML documents access each others' elements. Is there a script I can use on my computer that will securely verify these in my web browser and permit XSS access? Or, since this is only on my computer and I don't plan on releasing it to the web, should I just try to bypass the restriction from within Firefox - and if this is the case, how do I do that with local files only? I do not want to make myself vulnerable, nor am I trying to hack some other site. I just want my local project to work.
