Firefox won't let me log into my online banking.
I bank with a major bank (TD) and today, trying to log into my online banking, I get this:
Did Not Connect: Potential Security Issue
Firefox detected a potential security threat and did not continue to easyweb.td.com because this website requires a secure connection.
What can you do about it?
easyweb.td.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.
I just want to add that I have tried all of the "turn it on and off again" kinds of things - disabling addons, rebooting, etc. Still the same error.
The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.
This seems to be a permanent thing. Firefox will not let me log into my online banking site. I have never had this problem before and I have been logging into my online banking using Firefox for decades. What gives?
PS: Did all of the basic things like disabling addons, rebooting, clearing cache, etc.

Hi, when I try your link, the site redirects me to
Are you having the problem on that server, or was it before the redirect kicked in? Or perhaps the redirect itself wasn't allowed.
Is this the only secure site -- HTTPS address -- giving you problems?
If I follow your link, it loads fine, but if I go to their site myself by typing it in or clicking on a google search result, it loads only their main page, no secure pages on their site only. But this does not appear to be a Firefox issue, because the same thing happens in Chrome. I am updating Windows right now, that should prob fix it.
I truly wish I had not updated to the current version. I've had so many problems. The most important one being trying to get into my TD account. I go to sign in and for a brief moment I'm in my account and then suddenly the screen goes blank.
I haven't found a place for this comment yet so I'll leave it here. I absolutely hate the new look of Firefox. It no longer looker comfortable or friendly, just grey and blank with ugly industrial looking Windows and Tabs. As a Mac user I have been using Firefox on my Mac and all my devices. I'm going to change to something more inviting. This looks like something that we had in the late 80s.
Hi shelley.mycan, regarding grayness, Firefox's Default theme tries to integrate with your system theme. If that doesn't look good, try one of the other themes: Built-in themes in Firefox - alternative to complete themes. Changing from squared-off tabs to curvier tabs is a bigger project that probably is best discussed in a new thread.
Regarding website problems: if a site is generally known to work in Firefox, these are standard suggestions to try when it stops working normally:
Double-check content blockers: Firefox's Content Blocking feature and extensions that counter ads and tracking may break websites that embed third party content (meaning, from a secondary server).
(A) Do you see a shield icon toward the left end of the address bar, near the lock icon? More info on managing the Tracking Protection feature in this article: Content blocking.
(B) Extensions such as Adblock Plus, Blur, Disconnect, Ghostery, NoScript, Privacy Badger, uBlock Origin or uMatrix should provide toolbar buttons to manage blocked content in a page. There may or may not be a number on the icon indicating the number of blocked items; you may need to click the button to see what's going on and test whether you need to make an exception for this site.
Cache and Cookies: When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
(1) Clear Firefox's Cache
If you have a large hard drive, this might take a few minutes.
(2) Remove the site's cookies (save any pending work first). While viewing a page on the site, try either:
- right-click (on Mac Ctrl+click) a blank area of the page and choose View Page Info > Security > "Clear Cookies and Site Data"
- (menu bar) Tools > Page Info > Security > "Clear Cookies and Site Data"
- click the padlock or "i" icon in the address bar, then the ">" button, then More Information, and finally the "Clear Cookies and Site Data" button
In the dialog that opens, you will see one or more matches to the current address so you can remove the site's cookies individually without affecting other sites.
Then try reloading the page. Does that help?
Testing in Firefox's Safe Mode: In its Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, and some other advanced features to help you assess whether these are causing the problem.
If Firefox is not running: Hold down the option/alt key when starting Firefox. (On Windows, hold down the Shift key instead of the option/alt key .)
If Firefox is running: You can restart Firefox in Safe Mode using either:
- "3-bar" menu button > "?" Help > Restart with Add-ons Disabled
- (menu bar) Help menu > Restart with Add-ons Disabled
and OK the restart.
Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).
