add log time not working properly on firefox

add log time not working properly on firefox

Hi, before last update, with firefox I could do this:

open a task
go to the time log tab
add as many log time as I wanted by clicking on the blue button 'add log time'

After the update:
 - If I open the task with chrome, I can still add as many log as I want
 - If I open the task with firefox, I click on the blue button but nothing happens.

Can you replicate it?
