Okay, I have this same problem and am NOT happy, like the rest of you. Dx I will try the whole removing all add-on's and then re-adding them. But otherwise I have figured out two other ways around it, and they are not fun. o.o
First is to click that big red X and Stop loading the page, right before it starts to redirect you. I have done this by rapidly clicking it once the red X SEEMS to go away, but it comes right back.
But the best thing I have discovered, either open a tab (I am talking firefox now) and let the gaia page you are on load for 10-20 seconds while you are off on a different tab, probably on a different website. When you go back, amusingly enough, you won't get directed! You could also just open EVERY thing you click on gaia in a new tab (right click every link, this is pretty much everything for navigating gaia. XD ) And after you give it a bit to load, close the old tabs. Spend your time waiting in a different tab basically, no matter what.
Its just a PAIN!! XD
My biggest observation: for me, it only seems to redirect if it is loading and I am actually on that page. If it loads and finishes fully while I am in another tab. This is odd. I have no idea what that could mean, but thats a piece of info no one else seems to have noted. So hopefully it helps. ^_^
