Firefox Back button not working as expected: javascript displayed instead of html

Question

I am using History.js to make my ajax pages bookmarkable and to have the expected back/forward browser button experience. In Safari all works great but in Firefox 6 if I leave my site and then go back using hte back button I get the javascript instead of the page:

go to mysite.com/user/1/post_board
click on post filter, address changes to mysite.com/user/1/post_board?filter=one
enter google.com in address bar
push the back button
I see the javascript loaded at step 2

What is going? What I am doing wrong?

Here is the code:

// Bind to StateChange Event History.Adapter.bind(window,'statechange',function(e) { var state = History.getState(); eval(state.data.function_rest + "("+JSON.stringify(state)+");"); History.log(state); }); $('.message_filter').bind('click', function() { History.pushState({"function_rest":"restore_post_board_widget"}, document.title, this.href); return false }); function restore_post_board_widget(state) { $.getScript(state.url); }

Thanks for any help.

Does the url mysite.com/user/1/post_board?filter=one always return HTML? Or does it sometimes return JavaScript? — Boris Zbarsky

@Shef: I am open to suggestion on how to handle the history management. Using eval allows quite a bit of flexibility but again I am a total newbie to Javascript: stackoverflow.com/questions/7340906/… — Matteo Melani

just add:

window.onunload = function(){};

this is where I got the answer:

After travelling back in Firefox history, JavaScript won't run

That's the worst solution to your problem, it degrades browser performance. See stackoverflow.com/questions/7194095/… for the other options.

Thanks for pointing that out but even after reading the question you pointed to I do not see any other alternative. Can you point me in the right direction? Thanks.
