Best thing since sliced bread! Has worked flawlessly for me for years now, I have over 4K fics marked and it takes a long time to load the page, but it does load.

It's so helpful!! I can know which fics I've read as I'm scrolling through tags or author's pages, and which ones I might want to reread (based on the star rating I gave it).

I also am using this on 3 different devices, and the sync is a bit tricky at first, but works great once you've set it up initially.

I was using this for chrome for a while and it was absolutely perfect. No complaints. But I recently switched to firefox bc chrome shit the bed, and i can't figure out how to work this extension the same. i can rate individual fics on the ao3 website, but i can't get to the page where i can blacklist tags, which is a real shame bc i used the hell out of that feature. if anyone could help it would be appreciated.

What happened???! I lost all my ratings! Thousands of them! I'm heartbroken. When you read this much fanfic, the only way to save yourself from getting halfway through a fic and realizing you've already read it, is something like this. But only if it works!!!

I have the AO3 Savior as well as AO3 Kudosed and Seen History scripts in GreaseMonkey installed, but I use this add-on on top of all that because I really love the ability to rate fics for my own organizational uses based on how well I liked it (ranging from great to UGH, RUN!) and the kudos feature doesn't do much besides say "I liked it." I also like how the rated fics are organized based off the rating and if something is rated low enough it's hidden entirely.

I haven't used it for much else because of my other scripts, but I still use it extensively.

EDIT 11/30/20: So I've been using this add on for three years now and my previous review still stands, though now I genuinely love this extension and can't imagine navigating AO3 without it. It's a perfect way to hide fics I absolutely hate (without insulting any authors) or marking which fics I absolutely adored and it's perfect for helping me identify which stories I've already read.

My only issue is that, while this still works on Firefox, the search feature and the sorting feature inside the add-on itself are both broken. When I try searching for fics I've already rated or I try sorting by rating/name/author/etc. nothing happens. I've tried testing out the extension on Chrome and it works perfectly, so it's a browser specific issue.

this thing is usually a lifesaver except for one small issue i've run into three times now
it resets itself. occasionally i refresh ao3 to discover nothing blocked, nothing bookmarked, and go to look at the addon to see it completely blank. i don't clear my browser cookies or data and it seems to happen randomly
it's really fucking irritating and i'm uninstalling it now because i am so tired of redoing my admittedly large blacklist
sync tokens don't help, they just save the bookmarked stuff which i guess is nice but nothing else. silly me thinking it would work like that i guess

This is pretty useful for someone who doesn't already have Greasemonkey (Tampermonkey on Chrome) + the AO3 Savior script installed. It does a lot of what AO3 Savior does without the need to monkey around (ha ha) with userscripts. A solid extension all around for people who don't want to bother with userscripts.

Thanks, darthkrallt2.

This is super helpful, but is there any way it could also work in private browsing?

Thank you!

the worst things in life is when you go to read a fanfic about your OTP but AO3 is like here we'll include onesided!! and then ur NOTP is the main ship god bless u im saved yvy
