@BlackSheepNY, for what it's worth, I had the same issue as you today using Firefox.
I always use Firefox too, but today for some reason, I wasn't getting a pop-up after entering the CAPTCHA, and Toluna never loaded. A dump of cache and cookies and a reboot didn't resolve the issue.
I played around to see if maybe it was one of my addons causing grief, so I disabled all of the addons with the exception of flash, and even that didn't resolve it.
I used Chrome and it worked fine.
We'll see what happens tomorrow morning.
Maybe Firefox had an update, and something in the update is causing the glitch? Right now I'm on Firefox 25.0.1
Thanks for this post! It's nice to know I wasn't alone, LOL. My version of Firefox is the same as yours (25.0.1). Firefox hasn't updated lately, so I can't say it was the browser (since it's what I use 110% of the time). I thought maybe it was my OS (being Windows 8.1), but not sure about that, either. I've even been having problems with some of the surveys crediting on Firefox (where I never had a problem before). Obviously, something's changed - but where, I can't say.
For the time being, since everything seems to be working fine with it, I'll stick to doing Fusion Cash on IE 11 (even though I can't stand Internet Explorer). I was even able to complete an AMPSurvey and get credit for it RIGHT AWAY (which I've had many problems with getting credit on Firefox. I actually lost 3 credits and that's a lot of money.).
As far as the PTC goes, IE 11 seems to be working for that, too.
I read Admin's post and I'm glad he looked in to it.
Again, thanks to both of you for your posts.
