Emails used to display the sender's names but stopped displaying sender's name, happens in all email accounts viewed in Firefox. Once the emails are marked as Unread, the names are displayed as should be. Have cleared cookies and searched preferences for something to change. Mac OS 10.10.5, Firefox 63.0.

I found the problem, appears to be the AdBlock extension I have. When I disabled it, the sender's name appeared as they should when the emails are unread. I enabled AdBlock again and it worked until I visited a site that requested AdBlock to be activated and after that, the sender's names disappeared again. Disabled AdBlock again and sender's names appear. Thanks for replying.

Hi Dasman, when you use Firefox to view email, the columns available/displayed in your Inbox and other folders are determined by the email website you are viewing. Do you want to mention what site it is (e.g., Outlook, Gmail, Yahoo, etc.)?

Hmm, good sleuthing. Ad blocking extensions use a huge collection of rules to identify ads on pages. Sounds like one of those rules is mistakenly hiding part of your message list. Not sure where you can report that to get it fixed.

Hi Dasman:

Please tell if it's ok with you to share:

1. What adblock extension did you disable to make this work?

2. Which email service are you using? Gmail? Something else?

Cheers!
