I've started contributing to Mozilla in 2003, mostly filing bugs in bugzilla.mozilla.org. Since then I got to triaging bugs and finally I now code patches for the Thunderbird email client.
Use this query to see what I am working on: https://bugzilla.mozilla.org/buglist.cgi?f1=OP&f0=OP&emailtype1=exact&f4=CP&query_format=advanced&emailassigned_to1=1&j1=OR&f3=CP&email1=acelists%40atlas.sk
My focus of work is filters UI, account manager UI and small tweaks everywhere around the tree.
