Good and useful extension, but lately it shows the alt text tooltip on many (but not all) images regardless of whether that behavior is toggled on or off. Restarting Firefox doesn't alter that, nor does disabling and re-enabling the extension.

very good add-on, it's great to have options ! I thought of two things that could be great to add : a button in the pop-up to just toggle the whole thing on or off, and an option to copy the alt text to the clipboard (maybe in the right-click context menu)

Is AltVision: Image Alt Text Viewer 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.

AltVision: Image Alt Text Viewer requires a few sensitive permissions. Exercise caution before installing.

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.

AltVision: Image Alt Text Viewer may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
