Does not work: when opening a local json file ending with .json the extension does nothing.

Please roll back, the new version is undoubtedly a negative optimization

IDK what is wrong i checked every setting but this extension only works when it wants. I go to an endpoint and this extesion doesnt do anything. Really, it doesn't show me json at all. It worked a couple of times at the beginning of the installation & has not worked ever since. Machine: Macbook Pro Max M3.

When printing an object with id value like 149883901923910003 it truncates the last digit and it showed 149883901923910000 which is incorrect. It gave me a hard time trying to find the error until I disabled this extension, so keep an eye in the return values.

I can't find any explanation on this topic. https://github.com/rbrahul/Awesome-JSON-Viewer/pull/67

Can't trust the developer anymore. The original extension was marked as malicious(had malware) by Google. Even though the developer has a cover story stating that the extension was sold, not sure how much I trust that at this point. The developer disabled issues in his github repo after the issue blew up and deleted the issues (https://github.com/rbrahul/Awesome-JSON-Viewer/issues/60 and https://github.com/rbrahul/Awesome-JSON-Viewer/issues/64) that mentioned the exploit.

Do not trust author! Malware was added to the last JSON viewer extension he controlled.

If response headers the content-type is not application/json, it won't parse. I hope it could automatically parse when it detects the page content is JSON, regardless of the content-type header.

I love the ability to customize CSS but I have a bug to report: neither the light theme nor any of the custom CSS works, except on the most recently refreshed browser tab. All other tabs revert to default, and after clicking "Save changes", if the Light theme is chosen and custom CSS defined, all tabs show default dark theme with no custom CSS.

Very beautiful and helpful extend, but has a bug. For example: { "success": { "message": "Welcome to JSON Viewer Pro", "status_code": 198210283098489151 } } Serilize this json, this extend will change the status_code to { "success": { "message": "Welcome to JSON Viewer Pro", "status_code": 198210283098489150 } } I don't know why this will change my data, is this a bug?

Its good but the only draw back is that it does not capture json response unless the json header is set in the response header

when response's type is " Content-Type: text/javascript;charset=UTF-8 " and this plugin doesn't work.
