Important Notes for Manifest V3

1. Resource Types Valid resource types in Manifest V3 are:

   • main_frame, sub_frame
   • script, stylesheet
   • image, font
   • xmlhttprequest
   • object, media
   • ping, csp_report
   • websocket, webtransport, webbundle

2. Pattern Types

   • Wildcard: Uses * for capturing. Access captures with $1, $2, etc.
   • Regex: Uses standard regex. Access captures with $1, $2, etc.

3. Best Practices

   • Always specify appropriate resource types
   • Use ^ and $ in regex patterns for exact matches
   • Escape special characters properly (. becomes \.)
   • Include exclude patterns to prevent redirect loops
   • Test patterns thoroughly before deploying
   • Start with rules disabled for safety

Dark Theme

If you are a Firefox user and use a dark theme, you can add these lines to your userChrome.css file to make Redirector's extension button more visible:

/* Redirector button for dark Firefox themes */
toolbarbutton#toggle-button--redirectoreinaregilssoncom-redirector[image*="active"] { filter: invert(1) brightness(6); }
toolbarbutton#toggle-button--redirectoreinaregilssoncom-redirector[image*="disabled"] { filter: invert(1) brightness(2.5); }

If you don't know what the userChrome.css file is, or how to edit it, please look it up on a Firefox forum instead of asking about it in this repository. Thanks!
