Description of problem: Can all single-bug-related script URLs (such as process_bug.cgi and attachment.cgi) take the bug ID as a parameter (even if it doesn't use it in the script)? If my browser, desktop or computer crashes with a URL pointing to one of these pages then when the browser is restarted it will just go to process_bug.cgi or attachment.cgi and the bug I was on will be lost - which can be inconvenient. Similarly, I occasionally manage to set a bookmark on a bug without realising I'm on a URL that doesn't have the bug ID in the URL - then when I come back to it, I've lost the data.
If your browser supports history.replaceState (FF 4+, C 5+) and you have Javascript enabled, this automatically happens. Once the page is loaded, the URL will change to https://bugzilla.redhat.com/show_bug.cgi?id=X (where X is the bug number). I am also assuming your preferences is to reload the existing bug (which is the default for Red Hat Bugzilla). -- simon
