This happens on a regular basis for me. Once or twice an hour. I think it's happened for several versions. My first memory of the crash was a year or so ago, I think. I just chalked it up to an unstable custom ROM. This was captured on my stock Pixel 2 with the latest updates.
Confirming since I see crashes on both new pixel devices (Pixel 2 and Pixel XL) on 57 as well as 58. ni on Ioana to see if they have one of those devices to test.

Some comments:

*randomly scrolling on page when it went blank and then the crash happened 
*crashed when returning to the home page 
*I was reading something page by page when it froze.

Does it happen without uBlock installed?
Flags: needinfo?(landon)
Tried reproducing this using a Pixel (Android 8.1.0) with and without uBlock installed, but everything worked fine on the device. We do not have a Pixel 2 or Pixel XL here on hand to verify on any of those devices, will wait to see if Ioana can reproduce.

I've uninstalled uBlock. I will let you know what happens.

I'm convinced it's uBlock now.
So based on Comment 6, you didn't have any more crashes after uninstalling uBlock?

Although I cannot seem to get overall correlations, some of the individual reports I clicked on for 58 had no extensions installed.

I personally have not had crashes after uninstalling the plug-in. Should I report on the plug-in?

We can reach out to the addon author, but as I noted both signatures have users crashing without any extensions. 

The lion's share of crashes on signature are Pixel, Pixel 2 and Nexus 6P.

Trying an alternate ni to see if this can be reproduced.

I have been testing with a Nexus 6P running Android 8.1.0 and was still not able to reproduce a crash in any of the scenarios that I have tried, regardless of the fact that there were or weren't any addons installed. I will continue testing throughout the day and come back with further details if I find any relevant information or STR. NI-ing Ninu as well to look over this.

Could it have to do with the process being started through the URI handler? I'm frequently on Reddit and AFAIK, it could only happen when opening pages that way.

To clarify, I use the app "Reddit is Fun"

Thanks Marcia, indeed the other mail is not used. 
I spend the last two days trying with different addons in and also with reddit. As Bogdan said I am not seeing any blockers. 
Device: Android 8.1.0 Pixel 2

Just to make sure, Landon - is the app still crashing for you now again if u used the handler like in reddit?

Ioana, I do not know if that's what causes the crashes. I just know that probably 95% of the websites I visit are from other apps.
