问题
It's odd, I really don't know what else to check... I'm using this code for linkifying URLs...
And the URLs with a hash like Twitter http://twitter.com/#!/username/status/1234567890
Firefox shows this on the href: http://twitter.com/#%21/username/status/1234567890
The link works, but unfortunately, this brokes the Embedly plugin to auto-embed Tweets. In Chrome and Safari both, the Link and the autoEmbed are working fine. I checked on Firefox with an url without the "#!" and it works too...
So, I need to get Firefox to use "!" instead of "%21" (or any other special character for that matter)
Any clue on how to fix this?
Here is my .linkify code:
