Features & Capabilities

A helper to copy link title, "alt" image description, full timestamp, etc.

Developer tools are certainly more powerful when some text can not be selected directly but they are less convenient in some frequent cases. In addition to "title" and "alt" attributes, the following properties are tried:

chosen option of <select> element,
value of <input> form element that is suitable for date, time, color, range, etc. or its placeholder,
text of an element when selection is suppressed through CSS,
selected text, link target, or image source if nothing "better" is available.

Grant the notification permission in the add-on manager to be aware of failures to extract or to copy text.

The clipboard permission in add-on preferences makes copy action more reliable in Firefox-102 ESR,

Due to the browser security policy the add-on features are rather limited on privileged sites including addons.mozilla.org, for PDF files, etc.

See the project page for more details.

User Reviews

Simple, clean, does exactly what I wanted. I always write alt-texts for my illustrations, and when I have to share the same across multiple platforms, it's nice to be able to easily copy the alt-text.

Is AltCopy 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.

AltCopy 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.

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