Userscripts run in the web browser and make on-the-fly local changes to specific web pages. They generally change MusicBrainz pages to facilitate editing.
Note: A number of popular userscripts for MusicBrainz no longer work on Firefox 57+ and Greasemonkey 4+. See Greasemonkey#GreaseMonkey 4 incompatibility. Use Violentmonkey or Tampermonkey on Firefox instead.
To run userscripts, you need to install userscripts and an in-browser userscript manager to run them. Although Chrome/Chromium can run userscripts without installing a userscript manager extension, many userscripts will not work properly. It is recommended that you install a userscript manager.
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|
