Steps to Reproduce:
1. Save the following simplified HTML as a file and open it by Firefox.
2. Click "Refresh" button on the toolbar of Firefox.
var btn = document.createElement('button');
btn.disabled = true;
btn.innerHTML = "dynamic";
Both buttons are disabled after Step 2.
The static button is enabled and the dynamic button is disabled.
We have been fighting against this issue for whole day long and eventually we think it's a bug in Firefox. This happens only when you click the "Refresh" button of Firefox. Pressing Enter within the URL field refreshes the whole page and there's no such problem.
This issue has caused severe problem for our project and we need to forfeit a whole solution. Feedback are welcome.
We can reproduce the problem with the latest Firefox 3.5.3, as well as 3.0.13 and 3.0.14, on windows XP.
This bug is reproducible on Windows Vista with latest trunk, not with Firefox 2.

The bug still exists on Firefox 3.5.4 on Windows Vista and OSX.
If bug 654072 is fixed, we won't attempt to restore the disabled state, so I guess this will be fixed as well.

I have tested this issue on the latest Firefox (47.0) release and latest Nightly (50.0a1) build and is no longer reproducible. I have opened the provided test case and after page refresh the "dynamic" button is disabled and the "static" button is active.
I can confirm that this issue is reproducible on a older version of Firefox (3.5). After page refresh the both buttons are disabled.
Considering this, I will mark this as Resolved-Worksforme. If anyone can still reproduce it, feel free to reopen the issue and provide more information.
