Thanks for the advice, I've never met this link.

Well some other info according to this:
- CPU usage stuck on 25% (this computer virtually has 4 cores, so one core is on 100%)
- Nothing else runs wildly (some percents to task manager, when viewing)
- I waited as long as I could, Windows finally (I think after 30-60s) asked mi if I want to close the process or wait

I'm sorry, but I'm unable to give a crash report, I don't know if it's generated.

Is it reproducible with a fresh profile?

Try to store 1 or 2 passowrds an make your test.

Tested on two independent computers before.
Now as you adviced I created a new profile, and tried it. The result was the same

I see the issue in Fx44.0 & Fx44.0.2 on Win10, it seems works fine in Fx45.0b5 & 46.0a2 (2016-02-13) & 47.0a1 (2016-02-16). Also occur in 43.0.4 & 43.0 x64. Works fine in esr38.6.0.
