Oh, I forgot: You can add the Usersnap widget even to your live website, so your customers can leave feedback without installing a chrome extension :-)
You're right - every user action / step is hard for support.
We tackled this problem with Usersnap (https://usersnap.com ) - devs will get accurate information (Browser + OS version and a screenshot) directly with the bug report!
The creation part of snapbugz is just not ready for mobile/touch usage as UX patterns on the annotation part are different. However, the result / collaboration part is already finished: http://www.snapbugz.com/p/88a7a69a
Creating on mobile is on our agenda for the next week.
In the meantime, have a look at the result page for mobiles please: http://www.snapbugz.com/p/88a7a69a
You can extend the storage time by inviting others to discuss - 1day per invite. (If you already have sth like a bug tracker / pm in place - look at https://usersnap.com ).
For full HTTPS / IP-Restriction / Auth / external bug tracker support, please have a look at https://usersnap.com - this could fit your professional requirements.
