Userscripts are Greasemonkey scripts that run in the web browser, making on-the-fly local changes to specific web pages. In this context, they generally augment MusicBrainz pages and/or facilitate editing. You will usually need to install both a userscript runner (e.g., Greasemonkey for Firefox, Tampermonkey for Chrome/Chromium/Safari/Opera Next) and also to install the scripts themselves in your browser before they will work.
Note: A lot of the userscripts listed here will not work properly in Chrome/Chromium without Tampermonkey.
Could not edit MB without these:
|INLINE STUFF||musicbrainz.org release page: Inline recording names, comments, ISRC, PUID and AcoustID. Highlights duplicates in releases and edits.||Install|
These make MB much easier to edit
|Power Vote 1.0||Adds some buttons to check all unvoted edits (Yes/No/Abs/None) at once in the edit search page. You can also collapse/expand (all) edits for clarity. A handy reset votes button is also available + Double click radio to vote single edit + range click with shift to vote a series of edits. , Hidden (collapsed) edits will never be voted (even if range click or shift+click force vote).||Install|
|Funkey Illustrated Records||CAA front cover art archive pictures/images (release groups and releases) Big illustrated discography and/or inline everywhere possible without cluttering the pages||Install|
|mb. TAGGER LINKS NOW||Quickly show or update "TAGGER" links with desired port||Install|

|Link work to recordings||Batch linking a work to recordings||N/A|
|Extra MusicBrainz/AcoustID integration||Display additional AcoustID data on MusicBrainz mostly icons on tracks which have acoustIDs. Would be better if it did this anywhere a recording appeared, and maybe indicated how many acoustIDs there were.||N/A|
