Chrome extensions for Reddit threads and Bluesky lists
Reddit keeps half a thread folded behind "more replies" and shows you the same posts twice. Bluesky blocks one account at a time. These are small single-site tools for the parts of a social platform that never got fixed.
3 of 4 are live on a store.
Bluesky Bulk Block & Mute - List CleanerBlock or mute everyone on a Bluesky followers, following or list page at once, using your own session. Two-step confirm.
Hide Seen Reddit Posts - Auto Dim & ScrollHide seen Reddit posts as you scroll: already-viewed posts get dimmed or hidden so your feed stops showing the same ones.
Search Reddit Comments - In-Thread FindSearch Reddit comments across a whole thread, including collapsed ones, then jump between highlighted matches like Ctrl+F.
Reddit Load All Comments - One ClickNot published yetReddit load all comments automatically: expand every more replies, view more comments and continue thread with one click.
What to look for
A single-site tool should declare a single site
The three Reddit tools here match reddit.com and nothing else, and Bluesky Bulk Block matches bsky.app, bsky.social and the bsky.network hosts. Two of them declare no browser permissions at all beyond that. If something billed as a Reddit enhancer wants access to every site, that is the question to settle before installing.
Bulk actions are fast in one direction only
A bulk block works through your own logged-in session, calling the same endpoints your client calls, one account after another. Undoing several hundred means unblocking them in the platform's own moderation settings. Read the list page before you run it, and treat the two-step confirm as the pause it is meant to be.
Check which front-end it supports
Reddit runs several layouts at once: shreddit, old.reddit.com, the older React redesign, plus subdomains and locale variants. A thread or feed tool written for one layout will simply do nothing on another, with no error to tell you why. Search Reddit Comments and Hide Seen Reddit Posts state which layouts they cover — match that against the one you browse.
Local state is per-browser
A seen-post list, or your dim-versus-hide choice, sits in chrome.storage.local. That is why nothing follows you to another machine, and clearing site data can take it with it. Fine for a feed preference; worth knowing before you treat it as a reading history.
Questions people ask
Why doesn't Ctrl+F find every comment in a Reddit thread?
Because the browser's Find only matches text that is currently in the page, and long threads keep most replies collapsed or unloaded. Search Reddit Comments scans the whole thread including collapsed comments, expands the one holding a match, and steps through hits with its own shortcut so native Find keeps working.
How do I expand all comments on Reddit at once?
Either click every "more replies" link yourself or let an extension walk them. Reddit Load All Comments expands more replies, view more comments and continue thread in one pass, which is what you want before searching a big thread or reading it end to end. Very large threads take a while, since every folded branch still has to load.
Can I stop seeing Reddit posts I already scrolled past?
Yes. Hide Seen Reddit Posts marks a post seen when you click it or after it stays on screen for about a second, then dims it or removes it from the feed once it scrolls out of view, so the page never jumps while you are reading. You switch between dim and hide, or clear the history, from the toolbar popup.
Is it safe to let an extension act on my Bluesky account?
Look at what it declares. Bluesky Bulk Block requests no browser permissions and is limited to Bluesky's own domains; it acts through the session you are already signed into rather than asking for a password, and blocks stay reversible from Bluesky's moderation settings.
