Stop yourself from spending too much time on websites your know you shouldn't be. Set limits, automatically track your time, and block websites after reaching your limit.

Features & Capabilities

Disappointment. And a bit of Guilt. Two feelings I experience after spending mindless hours on the internet. It's a common story for me, and maybe for you. The story goes something like this for me: I get on youtube and tell myself "I'll just watch a few videos" or "I'll just watch one", but it's not long before I've spent a few hours and I'm watching "Seal farts after looking directly at me" and "Trump mistakenly calls Lil Pump "Little Pimp" at last rally". This happens all over the internet for me, but especially on popular websites: Facebook, Twitter, Reddit, etc. It happens because these websites are all built to keep me on them, and I think I have the self control to stop anytime, which obviously isn't the case, because I'm endlessly browsing.

After my last binge-spree I got sick of feeling disappointed in myself and spending hours of my life on mindless entertainment. That's why I made Cap, to stop the endless browsing.

Cap stops you from spending too much time in places you know you shouldn't. Here's what it can do for you:

  • Cap gives you the ability to set time limits on websites or categories of websites, and automatically keep track of how much time you've spent on each one. Once you reach your limit Cap will completely block you from the websites. When I say block I mean block. You're not going to be able to view it for 5 more minutes or anything like that.
    • E.g. I want to only allow myself 30 minutes on my social media websites every day. So I would create a category called "Social Media" and put my websites under it: Twitter, Reddit, Facebook. After I've spent 30 minutes total on these websites Cap will block me from visiting any of them.
  • Optionally allows you to set a bed time for yourself. When you set a bed time all websites become blocked after that time.
    • E.g. I have a bad problem with surfing Youtube when I'm suppose to be sleeping, so I set my bed time for 10pm, and Cap blocks me from watching those Youtube videos.

Is Cap 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.

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

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • Critical ****** ****** ** ******* ***** ***** *** ** **** ** ***** **** ******** ****** *** ******** ********** * ******* ********
  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
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.

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

Risk likelihood analysis details
