cubicweb #5555603 tests from web/test/test_jscript.py fail with a timeout [open]

I get for instance: RuntimeError: /home/dlaxalde/src/cw/cubicweb/web/test/jstests/test_ajax.js inactivity timeout (10s). 0 test results received

Apparently because there's no firefox available on the machine.

Tests should be skipped (or fail faster).
