It does its job!! Thank you for creating this
However, for some reason when I change anything it puts it entirely in bold?? (Ex. Y/N to idk Jessica becomes JESSICA) Could you fix that? Is it a problem on my end?

I'm giving this 1 star because I had to download and try it to find it doesn't work on normal web pages - just to alert other addon searchers.
It looks really good - better than FoxReplace because it has both find case and preserve case options.
Would definitely be 5/5 if it could be applied to general web pages (I wanted it for substack edits).
Or if the addon clarifies it doesn't work on any other pages. ✔

Is AO3 Word Replacer Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
AO3 Word Replacer requires very minimum permissions.
