Firefox browser site compatibility issues

I’ve encountered 2 annoying issues and am wondering if this is a Fx issue of site issues. Both sites work fine (of course) with Chromium/Chrome.

First, Paypal - if you try to manage automatic payments, the screen quickly flashes the correct format for the display and then all the payment accounts show up greatly enlarged, so it’s not even usable.

Second, Costco Warehouse Rx service just doesn’t work at all. If just shows a blank screen when you try to select prescriptions.

I’m sure there are other instances, I’ve luckily not yet encountered them.

What addons do you have active (Noscript, adblocker, Privacy Badger)?

Any clues you can give us from the Firefox console output (F12) when you see these problems?

Thanks for the nudge. I started in troubleshooting mode and this issue went away, so obviously I have an extension doing something bad. Now I just need to find it by process of elimination.

Well, this isn’t good… of all things that could cause the issue it is apparently Bitwarden. ugh…

Looks like you might not be the only one, ref: Reviews for Bitwarden Password Manager – Add-ons for Firefox (en-US)

I sent them an email explaining the issue. Hopefully they will fix it. If not, I’ll have to start looking for another password manager, and I really don’t want to do that.

Understandable. There are others out there. I use KeePassXC, personally, and haven’t had these issues with Firefox, but I hope Bitwarden is able to get this patched soon!

Thanks I’ll attach a sample so you can see what is happening with Paypal. Costco just shows a blank screen.

You should report it in Firefox:

It’s not only a problem with Paypal, but also Costco - and it disappears when I disable the Bitwarden extension. That being the case, I’ll let the Bitwarden folks figure it out. If they believe it is a Fx issue, they will advise.
