Countdown Timer Firefox

Countdown Timer

Counts down until a specified date and time of your choice.

Features & Capabilities

Countdown Timer is a lightweight Chrome extension that lets you create unlimited countdowns to dates you choose. Click the extension icon, enter a date, and watch the timer count down to the start of that day; each timer is displayed as a simple pie-chart on the icon for quick progress checks.

You can manage as many timers as you want. Completed timers auto-delete after finishing to keep clutter down. When no timers exist, the extension defaults to counting down to the next year, and dates in the past are automatically cleared to ensure meaningful countdowns.

Is Countdown Timer 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.

Countdown Timer 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.

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