FWIW I opened a PR some time ago [1] that would run all the tests on 
each commit to master in Firefox and Chrome nightly on Taskcluster [2]. 
We could certainly also use it (with a little effort) to run some per-PR 
jobs.

Obviously as a system TC isn't perfect, but it does have a number of 
advantages over Travis that could make it a good complementary system:

* Much higher available capacity
* Docker-based for greater flexibility and ease of debugging
* Possible to write a "decision task" that programmatically schedules 
jobs based on the changeset or anything else.

(Some of the most obvious disadvantages include:
* Not as widely used
* More effort to get the jobs running since docker requires setup and 
the configuration is more transparently a shell script rather than the 
travis thing of a .yml file that is converted to shell commands 
providing high-level features)
