One thing to remember, especially when considering the discussion of C++ at Netscape, it took awhile for most compilers to implement a consistent set of the C++ features. Netscape was being built across a dozen or so platforms and this was a major concern. If you have built Mozilla recently, the process to do so is not a couple of click action it is somewhat involved. It was worse way back when.
I've used C++ at the last for companies I have been involved with. The only consistency has been that no place used the same subset of C++ features. It usually boils down to what subset the team members are comfortable with. Variations have included exceptions or not, whether or not to use multiple inheritance, STL or Boost (yes, boost isn't really part of the C++ standard, but things like shared ptrs are in TR1), whether or not to use TR1, etc.
I personally don't have a strong opinion, but there are people that abuse C++ in ways that produce lousy code -- classes as a way to have nearly global variables, the whole C with classes approach, etc.
You really should use the right language for what you are working on and that plays well with any libraries you may want to use.
For curious folks, here is Mozilla's C++ Portability Guide (last updated July 2010, so it is still pretty recent). It is not a style guide. It contains some good lessons about writing portable code for "25 different machines and at least a dozen different C++ compilers."
