Recently we had some users report that their emails were not showing up after sending them. After troubleshooting and talking with the users they confirmed they used Dark Reader. The emails records did have the text they typed in the TEXT Body Field, but the HTML Body Field was blank. I saw the HTML tags when I exported the field via a SOQL query and inspected the page rendering the message. This happened after Dark Reader's last update on Jan. 9,2023. I'm curious to know if any of you experience something similar. I have directed the users to use the Salesforce Dark Mode extension by Salesforceblue.
If your users have access to Firefox, they can simply force change the background color in the browser settings. This of course affects any and all pages visited, but in my experience, most people who prefer dark mode prefer it everywhere. At least that way you don't have to worry about security issues from random extensions.
