User Reviews

thank you so much for this extension. I've been using it for a long time. I like customizing my pc a LOT and I love analog stuff like this, it's pretty well made and helps with time awareness and time blindness. I want to get more coding experience to try to make it into a windows software!! thanks again :]

just installed it Jan 2026. Love it! Exactly what I needed to remind me to stand up and get some water periodically. Works well. I wasn't expecting to get the full clock sound AND a number of chimes for every hour like a real church bell, but it's easy to just click the clock icon to acknowledge it and stop the continued dongs. If I may suggest: a grandfather clock option with only the first chime without the extra sounds for the hour number? Not a big deal but would be a nice option to have built-in.

Is Grandfather Clock 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.

Grandfather Clock 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.

Grandfather Clock is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
