★★★☆☆ sana · 18 Sep 2026 · v2.2.0was probably good in 2020 when it was released, but at this point it doesn't even block anything on ebay, much less anywhere else. seems your battle has been won

★★★★★ kaliam · 12 Sep 2026 · v2.2.0лёгкое и незаметное, но очень помогает каждый день

★★★★★ anon098714509 · 24 Aug 2026 · v2.2.0Blocks Intel from providing drivers. That to me is a sign that this plug-in works.

★★★★☆ zekromVale · 24 Jun 2026 · v2.2.0Please remove blocking local IP addresses, had enough issues setting up Mainsail. Or just add wildcard supports. Like 10.*.*.* or *.*.lan. Otherwise it's a fine extension unless your a tinkerer.

★★★★★ Ábel Póta · 14 May 2026 · v2.2.0Great extension that you just install and forget about while it still protects you against port scanning without breaking anything.

★★☆☆☆ Forrest Aldrich · 1 Feb 2026 · v2.2.0The extension eats a lot of resources and slows down, or interferes with the browsing experience. Such that I had to disable it. Now, this may mean there should be refinements or other adjustments -- this is just my longer term experience, and I had to disable it. The extension does expose an area that I feel Firefox should protect against natively, however.
