I've noticed that opening home.mendix.com for the first time in my browser, takes very long. Especially in FF it takes 15 seconds to load the page and before I see any content, the loading icon keeps loading :) In IE(it's unbelievable I know) and Google Chrome the page loads 3 times faster. I'm using version 27.0.1 of FF. Is it FF related or my own configuration?
We just found the issue, a patch will (most probably) releases next thursday. Thanks for the patience, it was a really tricky timing issue in combination with slightly different DOM api behavior compared to other browsers.
My Firefox loads in about 2 seconds, version 27.0.1 as well. Does it help to disable some plugins?
