A week ago I lost the ability to log in to my banking site (BBVA Compass). After submitting my username, it USED to then ask for my password on the subsequent screen. Now, it dies with a screen that shows "please wait", never gets beyond that. Looking in the error panel I see countless error messages for "error in parsing value" "declaration dropped", concerning a host of variables in CSS, such as radius, background, background image, etc. I CAN log in easily with MSIE. I have killed cookies and history, deleted and reinstalled FF, disabled the few add-ons I use, no joy. I have searched on these terms in "FF Help" and found some comments about these, but nothing that resolves the problem. This happens on several sites, I am including one.

  • Did you also clear the browser cache? This sometimes is needed when website have made update, to clear mismatched files.

orange Firefox button or Tools menu > Options > Advanced

On the Network mini-tab > Offline Storage : "Clear Now"


  • Do you have Firefox enter the password for you? In that case, you may want to clear the passwords for affected sites here:

orange Firefox button or Tools menu > Options > Security > "Saved Passwords" button


  • Are there other sites with a problem that don't require a login? We could visit the URLs and see whether we see an issue.
  • Regarding the Error Console (Ctrl+Shift+j), if you filter the list by clicking the Errors button at the top, you can isolate the most critical ones. A lot of the style warnings have no effect on functionality, just appearance.

You can ignore (CSS) errors in the Tools > Error Console.
Those errors are only useful if you develop websites and want to check the HTML/CSS and JavaScript code for errors.
Most errors are code for other browsers like IE or browsers on other platforms or just typos or the result of bad coding.


Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
