[Bug-gnuzilla] IceCat 60.3.0 Searxe's blocker causes crashes more often then before

[znavko]

Hello! I am using GuixSD, IceCat 60.3.0 on laptop Lenovo G50-30. I have a problem on this system (hardware or drivers): notebook freezes suddenly without no any key, mouse motion possibility.

Freezing was once per two days when I had previous version of IceCat, Searxe's blocker absented there. 

But on an IceCat 60.3.0 with only Searxe's blocker and Tor enabled I have 3-4 freezings a day.

So I think Searxe's blocker works badly.

I disabled this Addon in IceCat 60.3.0 and the situation got better. So I think there is a bug. Have no idea how to catch my laptop problem.

Freezing occurs in any page I'm reading, sometimes without high cpu usage (without media pages).

I had inserted cpu fan on Lenovo G50-30 that basically had passive cooling. Also I've inserted 8Gb DDR3L Ram, so these only changes.

I think drivers are bad too. Your options of how to track this issue in my pc are welcome.

Notable is that Searxe's hosting was hacked here https://searxes.danwin1210.me

Sorry, this is kind of dubious software source.
