Very effective ! Worked to download thousands presets on a bad website GUI.
Thanks

A bit cumbersome process selecting hundreds of checkboxes at dropbox, but unlike some other add-ons like Drag Select Checkbox, CheckThemAll works all the way. Saved my day. Thank you!

Extremely intuitive and works perfectly!

.

Great help! Please add an option to check all boxes on a page without having to select all text on the whole page.

It works great! Thanks!

easy to use and does it's job. thank you

This add-on is really good.

Hey this addon works great but do you have a version that doesn't require selecting all the boxes first? I would like to be able to check all the boxes on a webpage without having to specify which ones. Perhaps that's not programmatically possible?
Thanks!

It may work fine for certain applications, but not in my situation (Firefox v84.0.2 with Salesforce). Too bad, cause I need to turn off sh*tloads of checkboxes sometimes. These checkboxes are simply sitting inside an html-table, nothing fancy or unusual. Still looking for a working alternative.

I have been using this for ages. It is very useful in online education where I have to check a lot of boxes to change dates or send email to students. It works perfectly.

I only wish that there were an option to "check every other one" (or check ever Xth one with a drop down menu for X) to allow me to send email to every other (or every Xth) student. Then I could do the same and invert the selection and send email to the other students.

Not working currently.

Wow, where is this all of my life?
Glad I've found this. Though sometimes I don't know how much/less I should highlight.

This is exactly what I needed. I work in PeopleSoft over Firefox and one of the modifications we have is a directory where we can upload/download files. That page was modified so files can be deleted by the user. A checkbox is checked and then you can click Delete Selected Files. However, when there are many files to delete, clicking the boxes one by one was infuriating. This addon saved my sanity.

THANK YOU! Works great

I badly needed it and it works beautifully.
Thank you!!

This does not work at all for me in Quickbooks Online.

Thanks for the replacement for CheckFox. Working with Permission-Checkboxes on Drupal is a PITA otherwise.
