I noticed this week subtle, quirky changes in the Dumpshock interface when using Firefox after upgrading to v17.0. Javascript popups no longer appearing or being embedded in the page. Testing with Chrome, expected functionality occurred.
So, if you are using Firefox and things are not working as expected, I would suggest using another browser. Firefox is my primary browser, so I'll continue testing, but I don't expect we'll be making any changes based upon changes in one browser.
