Features & Capabilities

Kosher Browser turns your browser into a focused, intentional space. Decide what you don't want to see, and it stays out of the way.

Blocking • Category presets with 410 ready-made domains — adult content, social, video, news, shopping, gambling. One toggle each, ranked by real traffic rather than listed alphabetically. • Custom blocklist — any domain you choose, subdomains included. • Whitelist mode — block the entire web except sites you explicitly allow. • SafeSearch enforced on Google, Bing and DuckDuckGo.

Ads and tracking (optional, off by default) • Ads only — 105 advertising networks blocked, measurement left working, least disruption. • Ads and tracking — a further 45 analytics hosts. • Per-site exceptions for sites you want to support.

YouTube (optional, off by default) • Four modes: no limits, block entirely, block Shorts only, or allow only channels you approve. • Approved channels only: add channels such as @nickjr and nothing else will play. • YouTube ad blocking, independent of the mode you choose.

Discipline • Focus timer — 15 / 25 / 45 / 60 / 120 minutes or any duration; the countdown survives a restart. • Schedule — specific days and time windows, enforced even when categories are off. • Password lock, and strict mode which locks the off switch itself.

Privacy: nothing leaves your computer. No accounts, no analytics, no servers. The only two features that read anything from a page are the optional YouTube ones, and they compare it on your device and discard it.

Is Kosher Browser Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Kosher Browser requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Kosher Browser is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
