User Stylesheet to only view replies on your Bluesky notification page (no follows, likes, reposts)

bluesky-replies-only.css

/* 
This stylesheet can be used to hide all but reply notifications on your Bluesky notifications page (https://bsky.app/notifications)
 
You'll generally need a plugin such as https://addons.mozilla.org/en-US/firefox/addon/styl-us/ on firefox - 
  other plugins or ways of adding a user stylesheet are available for other browers.
You'll probably only want to enable it on the one page, and you'll have to turn it off to see any other notification types.

This stylesheet will work until something critical changes on the Bluesky notifications page. 
If it breaks, the [data-testid="notificationsScreen"] line is the most likely culprit - you can just remove it & the matching {}s
 */

[data-testid="notificationsScreen"] {
    [aria-label*=' followed '] {
        display: none;
    }

    [aria-label*=' liked '] {
        display: none;
    }

    [aria-label*=' reposted '] {
        display: none;
    }
}

If you don't want this to be always-on, you can also set your stylesheet plugin to only show it on a URL of https://bsky.app/notifications?commentOnly=true - then bookmark that page for a compact view.
