After travelling back in Firefox history, JavaScript won't run
firefox, javascript
Solution
Set an empty function to be called on window.onunload:
window.onunload = function(){};
e.g.
<html><body>
<script type="text/javascript">
window.onload = function() { alert('window.onload alert'); };
window.onunload = function(){};
alert('inline alert');
</script>
<a href="1.html">Click Me!</a>
</body></html>

Problem
When I use the back button on Firefox to reach a previously visited page, scripts on that page won't run again. Is there any fix/workaround to have the scripts execute again when viewing the page the second time? Please note that I have tested the same pages on Google Chrome and Internet Explorer and they work as intended. Here are the files and the steps I used to test the problem: (navigate to 0.html, click to get to 1.html, back button) 0.html ``` <html><body> <script> window.onload = function() { alert('window.onload alert'); }; alert('inline alert'); </script> <a href="1.html">Click Me!</a> </body></html> ``` 1.html ``` <html><body> <p>Go BACK!</p> </body></html> ```
