UPDATE (Aug 19, 2015):


If you wish to donate something (and some have asked) here is my Bitcoin address if you are so inclined:





UPDATE: I’ve upped compatibility for this to 4.0.* in CheckFox 0.9.2. I’ve also put the source into GitHub. The XPI is also checked in over there and can be installed from there:

I will submit this to Mozilla. I’ve found in the past that can take days, sometimes weeks. In the meantime, feel free to get it from GitHub, and sorry for such a long, long delay! Work and home life have kept me very busy in recent months.


What does CheckFox do? It allows a way to select an area of a page that contains checkboxes, and check/uncheck them. Seeing some images of it in action can explain it best, though.

With this in mind, this image shows a selected set of checkboxes that are all unchecked. A right-click shows “Check” as an option to check them all…

As another example, this image shows a selected set of all checkboxes that are all checked. A right-click shows “Uncheck” as an option to uncheck them all.

If the selection contains a mixture of both checked and unchecked checkboxes, both Check and Uncheck should show up in the context menu:

The site used as an example is Pull up main page, then click the “Create a Group” link.

CheckFox 0.9.2 is now available from CheckFox project at GitHub.

    I got Checkfox 0.9.1 this morning, from the extensions tab, when looking for updates. Perfect.

    Thanks for this extension, I use it a lot for forum moderation (where there is no “check all” link in interface, for example.

    How do I download and use this program on a MacBook Pro? This appears to only work with Windows. I really need this program to work with some Twitter websites, such as untweeps. Thank you.

    It doesn’t work very well for me on Linux: it takes 2 min 48 s to check 81 boxes, using FF 3.6.12, Ubuntu 9.10 (works well with Windows XP in the same case).

    This addon saves my life (well at least this christmas)!

    Just visited from the addons site to say thank you, this extension will save me ~5 minutes every time I need to copy a large group of pages in our cms (no need to click each of the check boxes for ~200 odd pages).

    First class, thank you for your time and effort!

  6. This is so fantastic and easy to use – just like Micro$oft not to put a Select All button on Outlook Web Access – with this addon it doesn’t matter.

    Except that I just installed FireFox 4.0. Can’t wait for this to be available on the new FF.

    Thanks for a great plugin, looking forward to using it again …

    Hi there –

    Simple, but great add-on. Any chance you’re going to update it to 4.x? I was looking for the XPI file to change it myself but couldn’t find it.
