The past, Current and future

Friday, October 10th, 2014

– The past –
I’m now about a year member of the A-Team (Automation and Tools Team) and also Fulltime Sheriff.

It was the end of a lot of changes personal and job wise. I moved from the Alps to the Munich Area to the City of Freising and (and NO i was not at the Beer Oktoberfest 😉 and working as Fulltime Sheriff after my QA/Partner Build and Releng Duties.

Its awesome to be part of the Sheriff Team and was also awesome to get so much help from the Team like from Ed, Wes and Ryan to get started.

At one time i took over the Sheriff-Duty for my European Timezone and it was quite challenging having the responsible for all the Code Trees with Backouts etc and also later checkin-neededs 🙂 What i really like as Sheriff is the work across the different Divisions at Mozilla and its exciting to work as Mozilla Sheriff too 🙂

One of main contribution beside getting started was helping creating some How-To Articles at . I hope that will help also others to get involved into sheriffing.

– Current –

We just switched over to use Treeherder as new tool for Sheriffing.

Its quite new and so it feels (as everything like a new car there are this questions like how i do things i used to do in my old car etc) and there are still some bugs and things we can improve but we will get there. Also its a ideal time for getting involved into sheriffing like with hammering on Treeherder.

and that leads into ….:)

– The Future is You – !

As every Open Source Project Mozilla is heavily depended on Community Members like you and there is even the oppourtunity beside all the other Areas at Mozilla to work as Community Sheriff.So let us know if you want to be involved as Community-Sheriff. You are always welcome. You can find us in the #ateam Channel on

For myself i’m planning to work beside my other tasks more in Community Building like blogging about Sheriffing and also taking more part in the Open Source Meetings in Munich.

Getting started in the Community… -> Today! :)

Monday, October 21st, 2013


i’m now over 10 Years a Mozillian and Part of the Mozilla Community (and now about over 6 years employee at Mozilla) and it still rocks.

I’m sure everyone involved into Mozilla has his own story how he/she got involved and here i my story:

How i got involved:

First, i never actively planned to join the Mozilla Community it just happened 🙂 I worked back in 2001 at a German Email Provider as 2nd Level Support Engineer and as part of my Job (and also to Support Customers) we used different Email Programm’s to find out how to set-up the Programm and so.

Some Friends already involved into OpenSource (the Linux Community) pointed me to this Mozilla Programm (at that time M1 or so) and i liked the Idea with this “Nightly”. Having everyday a brand new Program was something really cool and so started my way into the Community without even knowing that i’m now Part of the Community.

So over the years with Mozilla i finally filed my first bug and and was scared like hell (all this new fields in a non-native language) and not really knowing what i signed up when i clicked up this “submit” button in bugzillla 🙂 (was not even sure if i’m NOW supposed to fix the bug 🙂

So over the years with more involved into Mozilla and (in my case) with QA and Testing i got the offer to work at my favorite OpenSource Project and Browser in Full-time. And still super excited to work as part of this super great team.

And its still great to show new Community Members how to got involved

What i learned

Being a Community Member at Mozilla is something very special. Even from the first more active days in the QA Community i felt more than welcome and people are very thankful and helpful to show you the way and how stuff works.

I was never planning or hoping to get rewards etc when getting started, but contributing to a OpenSource Project like Mozilla is no one-way thing where you donate something to the Project. You get a lot back like interacting with a lot of people from different locations and maybe from around the world.

Also i learned a lot about Software Engineering like how stuff works and also about Teamwork and Co-working and also somehow improved my language skills a lot 🙂 Also you meet and work at least online with a lot of new friends. Thats all something you never get at one place in your normal day job (at least was my experience)

Lessons learned.

The most important lesson i learned over the years is “never afraid to ask questions”. Nobody is expecting you that you know everything. So never afraid to ask questions – its much better to ask someone instead of getting stuck on something where the answer might be a “mouse-click away” on IRC 🙂 Also this might also result in new insights into the Problem and Solution and maybe result in a way better solution than you were thinking.

Learn to accept that there will be mistakes – nobody is perfect – and there might be situations where you are on the wrong track or you made an error/ mistake. Happened as example to me too when i was verifying a bug wrongly in a Firefox Release that caused in the End a Re-Release of a Firefox Version. I can tell you i was super sad that day when i realized that i could have catched the Regression if i were digging deeper and with more testing etc…So yeah was a super bad feeling but then someone i got of motivation from other Team Members telling me that Errors can happen and thats its not the end of the world. So yeah that was super great at that day and reminded me that Mozilla is also not a one-man show its TEAMWORK!

We need YOU!

Open-Source lives from Contribution to the Project by the Community. So its never too late or bad timing to join the Project. There is always a place for you to join the Mozilla and also its a super great place to do you very own impact to make the web a better place to everyone. You don’t need to be a super code expert, there are a lot of Areas at Mozilla where you can contribute.

So yeah get started today!

What i do currently:

Like i said i started in QA and now working as Sheriff at Mozilla. Its part of the Auto Tools Team at Mozilla.

The primary responsibility of the Sheriffs is and will always be to aid developers to easily, quickly, and seamlessly land their code in the proper location(s) and ensure that code does not break our automated tests. In the service of this objective, the Sheriffs work closely with the larger engineering organization to create and enforce landing policies that increase productivity while maintaining an efficient and robust automated testing system. Beyond the policy role, they have also become shepherds of automation quality by monitoring intermittent failures, performing uplifts and merges, and identifying poorly performing automation machines.

And we are also looking for new Community Members!

Why not Community Sheriff 🙂

A Community Sheriff is working the other Sheriffs to keep the Code-Trees in a good shape and also working with Developers and also filing bugs for failing tests etc.

We are working currently on creating documentation to get new Community Members. So when you are interested in becoming a Community Sheriff let us know in the #ateam Channel on IRC (

Deutsche Firefox ESR Seiten und Mailinglisten online

Tuesday, March 20th, 2012


seit gestern sind die deutschsprachigen Seiten zum Firefox ESR online.

Firefox ESR richtet sich an Gruppen, die die Desktop-Umgebung in großen Organisationen wie Universitäten und anderen Lehreinrichtungen, Kreistagen oder Stadträten und Betrieben flächendeckend installieren und warten.

Neben der Webseite gibt es nun auch eine deutschsprachige Enterprise Mailinglist. Die EWG-Liste ist ein hervorragender Ort, um die flächendeckende Installation von Firefox mit anderen Mitgliedern der Gemeinschaft zu diskutieren und wird auch die einzige Möglichkeit sein, regelmäßige Mitteilungen zu Produkt-Updates und Hilfestellung zu erhalten.

Bisher gab und gibt es eine englischsprachige Liste und die deutsche Liste soll dazu beitragen, Fragen und Anregungen rund um Anwendung/Verteilung der Firefox ESR Version zu diskutieren und Erfahrungen auszutauschen.

Das Anmeldeformular fuer die Mailingliste ist hier.

Vielen Dank an alle die beim Uebersetzen geholfen haben.
