iMAboud/iMSteam ? reverse-engineered prompt

Build me a browser extension for Steam that shows extra alternative site links on each game page, right under the game name, so I can quickly open the related search page on different sites. It should work in Chromium and Firefox, and also as a userscript for Tampermonkey.

I want a simple way to add, remove, and reorder sites, plus customize the icons or labels if I right click them. The search should handle game names with or without special characters, and there should be support for a few common game search sites out of the box, with the option to add new ones by pasting in a search URL pattern.

Make it feel clean and easy to use on Steam, with the links appearing in a neat list and not getting in the way. If you need to look up current browser extension docs online, go ahead.
