User Reviews

Works with dual sidebars in Waterfox Classic 2019.10. Impressive. I'll keep in mind the invitation to add sites.

I like the idea, but I need this for ALL tabs, not just for particular websites.

Is Ideal Size 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.

Ideal Size does not require any sensitive permissions.

Risk impact analysis details
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.

Ideal Size has earned a fairly good reputation and likely can be trusted.
