User Reviews
Pros
- Useful and recommended by multiple users for everyday captures
- Easy to learn and use; straightforward interface
- Produces well-formatted results and includes basic editing/annotation features
Cons
- Full‑page/scrolling capture often fails or only captures the first view
- Visual glitches, cropping or ‘folded’ images reported on newer Windows systems (Windows 10/11) when making large/full screenshots
- Struggles with dynamic or protected content (React sites, ChatGPT dialogues, protected PDFs)

For some inexplicable reason this extension causes backtick characters in Markdown text entry boxes on GitHub.com to display incorrectly: rather than just being displayed as backticks, they're displayed as accents on the following characters.
There's no reason why anything this extension does would require it to change how text is displayed in textboxes on websites. This behavior is therefore somewhat suspicious.

DO NOT SIGN UP FOR A PAID PLAN! Nimbus was a fantastic extension when it was originally released. Unfortunately, I made the mistake of registering for an annual plan and now I'm trapped because there is no option to cancel the auto-renewal on their website (I think it may have been lost when the service transitioned to being Fusebase). Simply horrible experience in spite of it being a nice extension.

Is Nimbus Screen Capture: Screenshot, Edit, Annotate 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.
Nimbus Screen Capture: Screenshot, Edit, Annotate requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
