OpenH264 is unimportant compared to off-main-thread compositing (OMTC).
The off-main-thread compositing (OMTC) feature will allow for a fluent experience on less powerful hardware.
Make a world of difference.
OpenH264 supports, as was mentioned, baseline profile only. Most videos on webpages will be main or high profile, so OpenH264 can't decode them. But even if the video was baseline profile, it'd be accompanied by AAC audio, so you still wouldn't be able to watch it (because there's no OpenAAC).
What's the use of OpenH264 then? WebRTC. However, all browsers that support WebRTC have built-in VP8, and the two browsers that might not have built-in VP8 (IE and Safari) don't have WebRTC yet. As a result, all WebRTC communication is done with VP8, so OpenH264 won't get used even there.
To play H264 video on the web (along with AAC audio) Firefox will use Gstreamer, but it can also interface with ffmpeg directly, so you do not necessarily need Gstreamer for h264/aac HTML5 videos.

Mozilla needs to put more effort in Linux. But i don't think they care so much.
And it would be nice if they were putting some resources to Thunderbird also.

On their wiki it says the OMTC support is almost ready for linux too:
Current status
Shipped on all platforms except Linux (almost there on Linux as of Oct 6th 2014).
Linux
bug 722012 Mostly works, one reftest failure to figure out before we can enable OMTC and async-video (work in progress). Linux will use basic layers by default at least for some time, the GL backend can be enabled through a pref.

It's not only OMTC. There are many things. Notifications (without using an extension), MSE, gtk3, wayland, webgl with open drivers etc. Not all those are Mozilla problems/faults but are annoyances.
