Works very well except for pretending to be FirefoxOS by UA (I documented the issue on GitHub), maybe it's time for KaiOS?

Is Open in Sidebar 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.

Open in Sidebar requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

High Allows the extension to observe and analyze traffic in flight for the selected hosts.

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.

Open in Sidebar has earned a fairly good reputation and likely can be trusted.
