Since I updated Firefox a couple months ago (cannot recall exactly what version) when I try to log-in to the t-mobile website it loads the home page and asks for log-in info. When I enter it it then displays the t-mobile logo with dots on either side that swing back and forth and will just do that indefinitely. When I try to log into the CapitalOne website the home page comes up, I enter my log-in info, it goes to page https://myaccounts.capitalone.com/#/welcome and then should redirect to https://myaccounts.capitalone.com/welcome, but does not and it loads a blank page. This may have started about time they updated thier website but I cannot be sure. There have been a couple of other sites as well but cannot recall at the moment which ones. IE works fine, and Firefox 52.9.0esr on my old XP computer works fine (but of course is not secure).

Dear Simon,

There are two options (where I can get up with).

The first one is to contact T-mobile if this is a known problem at the moment.

The second option is to downgrade Firefox to check if it works. (Dont wait to long with upgrading it again ofcourse) See this link below:

https://support.mozilla.org/en-US/kb/install-older-version-of-firefox

Since IE does work, and XP also (which does not get updates anymore) it has probably something to do with the last update.

Please let us know!! :-)

You can try these steps in case of issues with web pages:

You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

  • hold down the Shift key and left-click the Reload button
  • press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
  • press "Command + Shift + R" (Mac)

Clear the Cache and remove the Cookies from websites that cause problems via the "3-bar" Firefox menu button (Options/Preferences).

"Remove the Cookies" from websites that cause problems:

  • Options/Preferences -> Privacy & Security
    Cookies and Site Data -> Manage Data

"Clear the Cache":

  • Options/Preferences -> Privacy & Security
    Cookies and Site Data -> Clear Data -> Cached Web Content: Clear

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window
