Hmm, you do have quite a few extensions that might be actively blocking things the page requires. Usually they have toolbar buttons to manage their behavior, for example, allowing the Capitol One site to run unimpeded. However, I haven't tried most of them myself. * AdBlock * Adblock Plus * DuckDuckGo Privacy Essentials * Ghostery You also could experiment with only using one or two of those at a time. I don't know whether "Hoxx VPN Proxy" is compatible with the site. Some sites are suspicious of indirect connections. The "Safe Search powered by Yahoo" extension (GUID {fd299ce1-1602-4490-b659-f45504f9324c}) was apparently blocked by Mozilla a few months ago, but seems to still be active on your Firefox. Maybe there is a glitch with the extension block list? You might want to disable that one. Of course, you can still use Yahoo if you prefer it by installing a search engine directly from their site. See the "Add a search engine from the address bar" section of this article: [[Add or remove a search engine in Firefox]].
