I'm a sys admin and security researcher and I'm not a programmer by any stretch of the word. Nor do I have a CS related college degree. I'm an anomaly in the tech world. ;)
I found an OpenSSL bug which was assigned CVE-2015-0208 (details forthcoming). I feel like that is a good achievement. Follows on the heels of the PHP5 bug I found in December(CVE-2014-9427).
1) open about:config 2) set gfx.webrender.enabled to true 3) restart Nightly
For the even more adventurous:
1) open about:config 2) set gfx.webrender.enabled to true 3) set gfx.webrendest.enabled to true 4) restart Nightly
