Public bug reported:
After installing Firefox 55 the browser generates huge cpu load, startup
is extremely slow (it takes > 10s for the taskbar to accept entries
after launch (this is new to 55)
Due to high cpu load the computer tends to overheat, ventilation jumps
in making the machine extremely loud.
Using Chromium does not show these symptoms (on the same page).
