I'll carry on giving tips on how to make better bug reports but I would like to ask your participation at the bug squashing week which will start tomorrow and will last 7 days.
What is it? The aim is to detect and triage the more bugs possible so that the next beta already will benefit of an improved quality.
How? If you can install the beta, you have 2 possibilities: either run it in any possible way and report all the bugs you find. Or help triage and reproduce the bugs already reported.
