If your browser doesn't work with the script in
>>1, try the following:
1. Change the @run-at from document-end to document-body or document-idle. Your browser may sequence things differently from chromium.
2. Try another script monkey plugin. I know of Greasemonkey and Violentmonkey, but there may be others I don't know about. There are non-cosmetic differences between the various script monkey plugins that may affect how the script behaves in different browsers.
3: Use
this version of the script. It will break any other scripts you have for the site, but it will work in your favorite browser.
