So I just tried logging into etrade and the moment I put the cursor in the username field this page renders: "Due to the presence of characters known to be used in Cross Site Scripting attacks, access is forbidden. This web site does not allow Urls which might include embedded HTML tags." I did a Malwarebytes scan and no pups came up. I was using Cyberfox so I'll try IE and see if that makes any difference. Then I'll CClean. I'm grateful for the extra protection, however, I do need to be able to log in sometime! Thank you! So sure enough, I could log on from IE but can't from Ffox or Cybfox. So I enabled Private Browsing and I can get in. I'm assuming etrade changed their security policy since I never changed anything!
Check for injections, and HTML rewrite type of hijacks. I've seen financial sites deny when they pick this up. Reset Firefox, then try. (Help/About, then Restart without addons) to try to isolate it. Could be a plugin too.
Thank you for this! Indeed, with both Ff and Cf in their safe mode (without addons) I could login. Will disabling one by one work or do I have to remove them? Thank you!
Mayahana and fax, thank you so much! It was Shumway, an HTML5 technology experiment that explores building a faithful and efficient renderer for the SWF.
