One issue that comes up frequently is that you're unable to 'click' the slots when booking a job.
This is easily solved by changing one of the core settings in your browser.

In the search field type in 'touch'.
On the "Touch Events API" change it from automatic to disabled
Click on 'Relaunch Now' down the bottom right
Firefox
Copy and paste about:config into Firefox
A warning will appear:
Click on the 'I accept the risk!' button
In the search bar type in 'Touch'.
Find 'dom.w3c_touch_events.enabled'
Click on it and a dialog box will appear that allows you to change the value of the setting.
