Frequently Asked Questions

I'm using the extension on Firefox/Safari. Is there a way to make it permanent?

Firefox: You can install it permanently using Firefox Developer Edition or Firefox Nightly by following the instructions in the Installation Help section above. This involves disabling signature verification, which allows unsigned extensions to remain installed.

Safari: Currently, Safari requires extensions to be signed and distributed through the App Store for permanent installation. The "Allow Unsigned Extensions" option only provides temporary installation that resets on restart. For users with an Apple Developer account, it may be possible to self-sign the extension, though this is not officially supported.

We plan to publish the extension on the Chrome Web Store, Firefox Add-ons, and Safari App Store. Once approved, you'll be able to install it permanently through official channels.

Is it possible to use the extension anonymously?

Currently, we require a Kagi Search account (even on the free plan) solely to prevent abuse. Since it's not feasible to show CAPTCHA challenges within the extension context, account authentication helps us maintain service quality and prevent misuse.

Your privacy is protected: Kagi Translate respects your privacy. Your translations remain private and we don't track or store your translation content, even on the free plan.

We understand that some users prefer not to use an account at all, and we're exploring alternative solutions that would enable truly anonymous usage while still preventing abuse.

Is Privacy Pass supported with the extension?

Privacy Pass is currently not compatible with the Kagi Translate extension. When using Privacy Pass, the authentication tokens provide anonymity by design - the server cannot determine which user is making the request. This prevents us from verifying your subscription status and translation limits when requests are made through the extension.

For the extension to work properly, we need to validate your account permissions in real-time, which isn't possible with Privacy Pass's anonymous token system. If you want to use the extension, please ensure Privacy Pass is disabled.

We're exploring solutions to make Privacy Pass work with the extension without reducing the privacy guarantees it provides.
