advice you’re unlikely to need
If you happen to want to install Firefox on Amazon Linux, say, so you can set up a continuous integration server that needs to run Selenium tests:
- Grab the binary package from Mozilla. Don’t try to be clever and use the one in the CentOS repositories; it segfaults.
- yum install dejavu-sans-fonts dejavu-serif-fonts, or you will get little boxes instead of letters when starting up.
