User reviews

Users appreciate the add-on’s ability to handle large JSON files and provide robust editing features like formatting, sorting, and collapsing JSON structures. However, multiple reviews highlight its lack of proper Firefox integration, requiring manual copy-paste to load/save JSON data. The UI suffers from very light, small text without customization options, leading to poor readability and awkward usability. Overall, while it is a valuable tool for developers needing editing capabilities beyond Firefox's native viewer, its user experience and integration limitations reduce its convenience.

Pros

Can open and edit large JSON files that Firefox's internal viewer cannot handle.
Provides features like formatting, sorting, and presenting JSON data in a readable manner.
Includes collapse/expand all options for easier navigation of JSON structures.
Serves as both a JSON beautifier and editor, offering editing functionality beyond simple viewing.

Cons

Lacks integration with Firefox's native JSON viewer; cannot open JSON files directly from Firefox without copying and pasting.
Does not support loading or saving JSON files directly; users must manually copy and paste JSON data in and out of the editor.
User interface issues such as very light text colors and small font size, with no options to customize colors or zoom for better readability.
Has an awkward or less intuitive user experience, making it difficult for some users to use effectively.

It works... Not as expected, but it works... I expected it to be integrated with Firefox, opening a JSON file directly from it, or entering edit mode on an open JSON (since Firefox 53, JSON files are natively viewable in it, so there's no need for JSON viewer extensions.) Long story short, it doesn't. Not only that, but it also cannot load or save JSON, it literally is a JSON editor, ONLY an editor, without any other functionality, not even load/save! The JSON data must be copied and pasted into the editor window and, after any editing is done, the code copied and pasted back out into a JSON file. The editor is awkward to use (at least, it has collapse/expand all options).

Extension safety

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.

JSON Beautifier & Editor requires a few sensitive permissions. 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.
High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****

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 Browser Add-ons, 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.

JSON Beautifier & Editor is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
