User Reviews

Users like Notes by Firefox for being simple, intuitive and useful as a distraction‑free desktop/sidebar note tool. Major recurring complaints: the sync feature was removed, the add‑on is no longer maintained (no Android/mobile support), and there are visual/theme issues such as a buggy dark mode. Overall: good for local desktop use but missing sync, mobile access, and recent updates.

Pros

Simple, intuitive and easy to use for quick notes
Works well as a desktop/sidebar note-taking tool
Minimal, distraction-free interface favored by users

Cons

Sync feature was removed or no longer works; users repeatedly ask for it to be restored
No mobile/Android access; extension appears unsupported or abandoned
Not updated/maintained for years
Visual/theme problems: dark mode is buggy and the add-on often ignores browser theme colors

Recent reviews

It's the best I could find. Pastes rich text but not links or images. Well laid out with headings list page clicking to open the edit page and arrow back.

Is Notes by Firefox 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.

Notes by Firefox does not require any sensitive permissions.

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.

Notes by Firefox has earned a fairly good reputation and likely can be trusted.
