It doesn't work more, just stopped. :/

Just installed, doesn't work, doesn't show or record any time.

Doesn't seem to work. Icon visible but no time. Summary page is blank & menu doesn't work. Ironic that an add-on designed to stop wasting time actually does the opposite.

It doesn't work. That didn't timed anything.

Unable to get the add-on to work. The hourglass is there in the menu bar where it should be, but it's not possible to turn the timer on.

i really wanted to like this add-on, but it simply does not work at ALL for me :(

I've just installed this addon, but it doesn't work (running Firefox 63). A shame, because it was exactly what I was looking for.
Currently, the toolbar button flashes for like 1/10th of a second when loading each page and is disabled right after. Clicking on it when it's lighted up still gives access to the summary, which shows no time has been counted whatsoever.

Keeps counting when my computer goes into sleep mode. Please fix it.

Unfortunally the Add-On doesn't work anymore. I can't access the summary page and the timer doesn't count anymore. I loved that function
