I know it's not FSM as I am having problems connecting with other websites. (but not all)
All of a sudden I can't connect to FSM and many other sites from one of my two computers using FF.
Ergo the problem has to lie with your firefox as your internet connection works on the other computer. Perhaps that imageresize is a plugin of sorts on FF? Or it could be a malware infection redirecting your browser, I would run a scan to be certain and see if that helps. Or re-install FF.
I'm thinking it might be an add-on issue. Or a conflict when I installed FF Developers edition. Though these problems are happening on one computer and not both. And I installed FF Developers on both. BTW I am answering this on the "troubled" computer via FF Developers browser. Just can't access this page via regular FF.
Edit: Thanks for putting me in the right direction. I turned off all my add-ons and now the site is back! So I just got to figure out which one is the issue.
Edit 2: It was some add-on called "searchme". I have no idea why that was installed. I didn't even know what it did. Weird. But that fixed the issue.
