I don't think "Tabs" is the right topic, but maybe it's the best of the choices since "Other" isn't an option. I have an email with a link to a monthly newsletter, which should take me to February's issue. When I click on, or copy/paste, the link, I end up with the January issue. When I copy/paste in Chrome and Safari, I get the February issue. The newsletter people suggested clearing my cache/cookies in Firefox, but that didn't help. No matter how I try to navigate to the newsletter in Firefox, I get to January. I have tried everything I can think of, and still get the January issue in Firefox, while that same link gets me the February issue in Safari and Chrome. I'm using Firefox 122.0.1, on a MacBook Pro (Sonoma 14.2.1). I'd appreciate any ideas you might have! /edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have <b>macOS</b>.
