Status: RESOLVED DUPLICATE of bug 193887

(Core :: DOM: Navigation, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3b) Gecko/20030124

Javascript links that declare variables causes back button failure.  This bug
affects both in-page links and bookmarks, and breaks many "bookmarklettes".

eg. 
  javascript:var darrenVar='test'; location.href='http://mozilla.org';

Reproducible: Always

Steps to Reproduce:
1. Paste the following into the URL bar: javascript:var darrenVar='test';
location.href='http://mozilla.org';
2. Click through any link on the mozilla.org page
3. Use back button to return to mozilla.org

Actual Results:  
Back button does nothing but produce javascript error.

Expected Results:  
Return to mozilla.org page.

At step 3, the back button causes the following js error: uncaught exception:
Permission denied to set property Window.darrenVar

I think this broke right around the time that 'location.href="URL"' started
displaying the URL in the content window, before navigation.

to session history; we're going back the the "javascript:" url and it's failing
miserably....
