User Reviews

This seemed like the perfect extension for cataloging offline web pages until... After saving around 100 pages, every attempted save thereafter results in: "Error: The snapshot has been made, but it could not be stored in this extension's storage. Just saving it among your downloads instead.." Apparently this extension doesn't invoke Mozilla's "unlimitedStorage" permission and therefore only 2GB of snapshots can be made. After that limit, snapshots are saved in the system's default downloads directory, but cannot be searched via the extension. What a buzzkill.

I don't know if it supports cloud, like Dropbox, or anything else like Gdrive, etc. If it doesn't support any cloud (I don't use Webdav), could you add this feature please?

Is WebMemex 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.

WebMemex requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

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.

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