Sorry but the instructions to are not even clear at all, so i can not even use it due to terrible instructions.

The instructions say:

"You find the extension in the drop-down menu of the bookmarks/history sidebar. (Ctrl/CMD + B toggles the sidebar)"

What do i press?? I cant find a "CMD" key on my keyboard? what does this mean?? do i need to hold down control + cmd + B? Or does it mean either ctrl or CMD + b? Either way i couldn't find CMD button so that never worked and when i tried just Cntrl + B that opened a side bar but there was nothing in that side bar that i could find that said anything like checkmarks.. love to use it but the instructions are so terrible i couldn't i tried for a half an hour.....

UPDATE:
Ok After looking deeper I have actually figured this out and will give proper instructions to others having this issue, as i read through the comments and noticed others had issues getting it working as well but none of their instructions were clear enough for me either.

Here is good clear instructions that work:

1) Install checkmarks addon to firefox

2) Ensure you have the "menu bar" enabled in firefox. (To enable this menu bar right click on the "white space" around address bar ... a small menu will pop up and make sure you have a checkmark beside "menu bar")

3) On firefox browser Open View/sidebar/checkmarks this will open a sidebar on the left side of your screen

4) On the left of your screen directly under "checkmarks" is a little arrow facing right with a circle around it (also known as a play button) click the play button for it to refresh your icons 5 at a time.

5) optional: disable menu bar again if you want it off by doing exactly same thing as step 2 just this time uncheck "menu bar"


With proper instructions this addon is great but since I had to basically figure this all out on my own after wasting an hour + of my day

3 star.

Fix the instructions, and this would be a great addon. Just such unclear instructions im surprised anyone could get this working.
