Saving files Firefox extensions can’t write directly to a folder of your choice. Files are saved to your Downloads folder, inside a subfolder you can name in the settings. Choose “Ask each time” to get a Save As dialog. To save into Documents, set Firefox’s download folder to Documents in its settings.

Is Writer Studio 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.
Low risk impactLow risk impact

Writer Studio requires very minimum permissions.

Risk impact analysis details
  • Medium Allows management of download operations but generally doesn't severely affect security unless misused.
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.
High risk likelihoodHigh risk likelihood

Writer Studio is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
