They use firefox as main browser, but for using DRM content I found Chrome to be the easier solution.
They worked their way to LibreOffice, but regarding spell- and grammar-checking LibreOffice really sucks. As my dad does professional writing it was just not enough.
One thing to keep in mind about running Office on Wine (especially a version as old as 2007) is that the software has a number of known vulnerabilities, and the Wine installation breaks Microsoft's patching system(s). All patches have to be installed manually (unless there's a good script for this that I'm not aware of). Fortunately, most of the exploits will be designed to attack a Windows system, but it's still dangerous to leave it unpatched.
I don't remember details but I also had major problems there, must have been two years ago, in the summer. Updating the needed plugins stopped working for some reason. Can't comment on current state as I haven't used Netflix on Linux for quite a while.
