ProxyMaster 제작자: mikecoding

A rule‑based proxy switcher for Firefox. Set per‑site proxy rules, toggle global proxy, and get smart prompts when sites or resources load slowly or fail.

Key features:
- One‑click add/remove current site (exact or wildcard).
- Global proxy toggle.
- Rule types: domain, domain‑suffix, keyword, regex (proxy/direct/block).
- Auto prompts for slow/failed domains, including cross‑site requests.
- Optional community rule sync (fetch; upload only if you opt in).
- Import/export settings, rule sources, debug logs, and proxy status.

Works with local HTTP/HTTPS/SOCKS5 proxies (e.g., Clash at 127.0.0.1:7890). Not affiliated with Clash.

Privacy:
- No browsing history is uploaded.
- Rule sync upload is opt‑in and sends rule metadata only (domain, match type, action).

根据域名决定tab是否使用代理，支持自定义规则源、自动更新、全局代理与按域名代理，网页加载失败/过慢时自动提示是否走代理。
