Not sure how I missed this post when looking before making my own. Apologies. I'm going to copy my posts over to here. 1/2
The raindrop.io bookmark manager lets you highlight text on web pages and it saves these highlights (see below for intended behavior). In Orion, the highlights aren't shown, and I tried both the firefox and chrome extensions.

- Install the Raindrop.io extension
- Click the extension in the toolbar and log-in with google or similar.
- Select some text on the page example page and select "Save highlights"
. It may request additional permissions at this point.
- See that the highlights are not being persisted.
Note: I have trouble enabling/allowing the Raindrop extension with compatibility mode on, so I was not able to test that way. I did however test with a new profile and faced the same issue.
Expected Behavior (Safari/Firefox)

We see the highlights in Safari.

We see the highlights in Firefox.
