I agree with the below review by Fernando.
I used to use this extension on Chrome, but recently switched to Firefox.
I couldn't upload my downloaded data from Chrome.

"Time Tracker - Web Habit Builder by zhy" is the way to go. Can accept data from Webtime Tracker and has way more free features

Cannot recommend this one, just lost all my data that I had backed up, tried to restore after and it simply does not work anymore.

Restore functionality is very limited even when it works, it just overwrites all data, doesn't give any options to keep the current data or anything.

Also only shows the history of the previous 3 days, if you want more you have to pay.

There's a far better option: Web Habit Builder

ayy, this was exactly what I'm looking for! Thank you for making this. On a side note, I've spent 2 full days on Wikipedia over the last year and a half... I'm becoming a nerd hehe

Weird tracking behaviour for 8 minutes of a website it only recorded 3. Maybe inactivity dunno doesnt work for me

Exactly what I needed – the time tracker for each site in the icon. Thank you.

Warning: this is not actually completely free. You need to pay to see more than 3 days of detailed history. I wouldn't mind if this was clearly written in the description, but this is conveniently not mentionned anywhere, not even on the homepage!

nice. but I found another alternative called Web Habit Builder. If you finish the features that one has, I will reinstall webtime tracker again

Can you make this opensource? Thank you

Exactly what i'm looking for - thanks
