Features & Capabilities

Every tool on toolz.dev, one keystroke from wherever you are.

Press Alt+T, type three letters, hit Enter. No aiming at a toolbar icon, no tab full of bookmarks, no remembering which site had the JSON formatter.

RUNS IN THE POPUP, OFFLINE Five tools work without opening a tab and without a network connection:

• Base64 encode and decode, Unicode-safe • JSON format and minify, with the parse error if there is one • URL encode and decode, both encodeURIComponent and encodeURI • SHA-256, SHA-384 and SHA-512 hashing • Case conversion: camelCase, PascalCase, snake_case, kebab-case, CONSTANT

Whatever you paste is transformed in the popup on your own machine. It is never uploaded, never logged, and never leaves the browser.

FINDS THE REST Search the whole catalogue by name, keyword or category, or browse 28 categories: PDF, image, data, CSS, SEO, security, converters, calculators and more. Favorite the ones you use and they stay at the top.

Type "tz" in the address bar to search without opening the popup at all.

WHAT IT ASKS FOR One permission: storage, to remember your favorites on this device.

No account. No host permissions, so it cannot read or change the pages you visit. No content scripts. No analytics, no tracking, no profile. Your favorites are stored on your device and are never sent anywhere.

Is Toolz.dev - Developer Tools 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.

Toolz.dev - Developer Tools does not require any sensitive permissions.

Risk impact analysis details

Low Allows usage of omnibox input, negligible risk as it pertains largely to user input enhancements.

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.

Toolz.dev - Developer Tools is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
