=============================================================
crashes with this signature on windows 7 & upwards are continually rising since mid-december - currently there is a volume of around 100 daily crash reports. 

correlations from 51.0.1 indicate that this may related to one of mcafees update to the addon (versions 5.0.360.0 & 5.0.432.0 look affected):

Comment 1

[Jorge Villalobos [:jorgev] (he/him)]

Various updates seem to have gone out since. Are the crashes significant in number?

Comment 2

[[:philipp]]

their updates haven't made much of a difference to the better it appears.
 
by volume this crash is ~0.13% of all browser crashes on 51.0.1 in the past 7 days, which i'd say is mid- to low-level, but not totally insignificant.

Too late for firefox 52, mass-wontfix.

Comment 4

[Marco Castelluccio [:marco]]

[Tracking Requested - why for this release]: Top crasher in 55.0b.

We could consider blocklisting the DLL.

Comment 5

[Julien Cristau [:jcristau]]

Tracking the increased crashes in 55beta in bug 1376514.

Comment 6

[Chris Peterson [:cpeterson]]

I don't see any crash reports in 57 or 58. The crash reports had "McAfee SiteAdvisor" legacy add-on {4ED1F68A-5463-4931-9384-8FFF5ED91D92} installed. Let's wait and see that these crashes should go away in 57.

Comment 7

[Marco Castelluccio [:marco]]

If I remember correctly, they are switching to a WebExtension and they are no longer going to load the DLL.
