User Reviews

UI is super confusing. What's the rules for page name? Is the time limit in seconds? minutes? What does the R button do? Why is it an overlay that's constantly on the screen? It should be, like every other addon I use that's pinned in my firefox toolbar, a window that only appears when I click the extension icon. I'm not speedrunning web browsing, I don't need a timer constantly showing. The page time limit and break length only show if I manually extend the popup horizontally? The extension technically does what it's advertised so I'm not giving 1 star, but the fact it's constantly on screen is annoying.

The configurability is amazing! You can set a limit for Firefox, each individual website, or for all websites. You can also whitelist some websites to not have a time limit. It's great for productivity!

Is Time Limiter 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.

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

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.

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