TagVision per Santa Tollimus

TagVision (TV) adds advanced tag filtering to Twitch category directories.
Twitch normally allows only one tag filter at a time and does not provide a way to exclude streams by tag.
TagVision adds those missing controls directly to Twitch.
Click any visible stream tag and choose:
Green - required tags.
Red - excluded tags.
Clear - clear all existing tags.

TagVision also improves directory browsing by displaying streams in a compact one-column layout and allowing full stream titles instead of being truncated.
Filters persist while browsing between Twitch categories.
TagVision stores filter preferences locally in Firefox. It does not collect analytics, transmit browsing data, require a Twitch login, or communicate with an external server.
