p.s. Restarted Firefox in Safe mode, same problem.

Please try opening the site in Private Browser Windows

This helped but only off-and-on.

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You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.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 for websites that cause problems via the "3-bar" Firefox menu button (Options/Preferences).

"Remove the Cookies" for 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

I have the problem with logging into RBC. Opening in a private window did not help. The problem arose last weekend (Jan. 18/19) after many years of using Firefox to log into my RBC account.

RBC posted a note that they are working on the problem. From the timing i think it was triggered by a recent Firefox release. As of yesterday the problem seemed partly resolved, but still there.

Having the same problem. Tried private page still will not load as of Jan. 22, 2020. I am hoping this will get resolved soon, I real don't want to use a different browser.

Still an issue today, sometimes works and sometimes not. Usually not. RBC still recommends using a different browser. I've reluctantly had to go back to Chrome to get predictable access, and have had no problems with it.

I encountered the problem today. I was able to sign in with Firefox 72.0.2 in the morning okay, but later all I got was a blank page with a feedback tab on the right. Private window doesn't help. Chrome works, but I'm not interested in workarounds. Is RBC and/or Mozilla working on this?

I had this problem a week ago, it seemed resolved for a couple of days this weekend, and now it is back. I have Firefox 72.0.2. Safari works fine but that is just skirting the issue. RBC seems to be passing the buck; they point you to seek help from Firefox. I wish someone would accept responsibility for diagnosing this and fixing it! -- John

I just managed to sign in normally. Hopefully the bug is fixed,

It's not fixed. I just tried to sign on a few times and failed each time even in a Private Browser Window. The funny thing is that I tried Chrome as well just after my first failed attempt using FireFox and Chrome failed as well. I believe that the problem is with RBC rather than any particular browser but Firefox may exhibit the issue more than the others due to a timing differences between the browsers.

Yes, perhaps I spoke too soon. I went to sign in about 20 minutes ago and again got a blank page. I clicked my bookmark again and was able to sign in. So it's not properly fixed yet.

I found a maybe similar issue with a different site today. http://www.londonrvshow.com/coupon/ lets you print a coupon for admission reduction to the London Ont RV show. Firefox would not show the necessary sign-up form though, but it worked fine using Chrome. Maybe there's some extra-security setting in Firefox that's stopping this type of thing,maybe related to the RBC issue?

This morning I could not sign in with Firefox 72.0.2 at all no matter how many times I tried.

Accessing RBC banking problems started Feb 3. I can access with Chrome and using Private Windows. So, the problem has not been corrected and is obviously a Mozilla issue. I use Windows 7 so any thought of a Win 10 connection problem is not correct.

This thread started January 15 with someone using Firefox release 72.0.1. I noticed it Feb.3 with version 72.0.2 which was released Jan. 20, but I don't remember when my FF updated. We'll just have to wait and see if the next release fixes it.

3 weeks for some and the problem still exists. Poor. I am setting my browser default to Chrome because I access RBC a number of times every day.

I had Chrome fail on me to log in the other day so I'm not sure Chrome is viable longer term solution.

I have the same problem using Firefox but Safari works just fine. I hope that someone finds a solution to this soon.
