We stumbled upon this while testing a simple CSS scale transition for a new item: worked as expected with all major browsers but epic fail with Firefox. (image jumping to another position)
After a medium-to-long wtf-ing session, we were able to create a test case on jsfiddle and conclude this is a browser bug, here’s the test link:
Please check and post here if the bug is happening for you as well + your Firefox version as we’d like to file a bug report with Mozilla for this issue.
Looks like a bug, yes. I found one in Firefox myself while developing an item, it triggers the transitions on mouse over, while they should only be triggered on :target.
Yes this is definitely a bug. Testing this in Firefox 10.0.2 on OSX Snow Leopard.
I also have found another bug in Firefox for Windows (maybe only Windows 7), and that is Canvas shadows do not work there. The shadows show up fine in Firefox for Mac.
