I got this crash now 2 times in last week with Firefox 56 Beta: https://crash-stats.mozilla.com/report/index/256464d3-4834-47bb-bd9e-333c50170830
I can fairly regularly reproduce this issue when I have large GitHub issue pages open.
(In reply to Josh Triplett from comment #4) > I can fairly regularly reproduce this issue when I have large GitHub issue > pages open. Can you provide example pages, and what you're doing to trigger the crash? Or is loading the page sufficient?
Loading a github issue page and waiting, that's it. Often, I'll use the session restore mechanism after the crash, and a minute or so later it'll crash again, without interacting with it at all. In case it matters, I'm logged into Github. (Which changes some of the UI elements present on the page.)
Thanks for the information. I'll try leaving the Github issues pages for Angular and Bootstrap open and see if it crashes.
I'm still encountering this, dozens of times every day, on two different systems. I've submitted numerous crash reports; look for those that have github.com URLs.

A NodeJS pull request, one that 404s (presumably from a private repo) and some .md file. I'll leave those two open, along with the other ones. Could you post the crash id from about:crashes? Also, does this reproduce in safe mode (maybe an addon is causing this somehow)? Thanks. Hmm, I thought I'd added an annotation for the object that is crashing, but I guess that's for another place. I'll file a bug for that.
Here are 7 from today: bp-d4b1a90b-60a3-4526-b8f4-31ce61170915 bp-54787d18-17c8-474c-853c-112551170915 bp-2114558b-4119-42e7-9f31-6b4e01170915 bp-09fccf4e-86e1-44d5-8fe3-208a91170915 bp-080e2d20-0465-421f-ba1a-ba9101170915 bp-c9dac141-b7e7-4cc8-b6b3-c6c8f1170915 bp-020990de-4b97-4163-8f6e-7a4f51170915
I'm not sure, but I think I might have a hypothesis here. I disabled the It's All Text extension, and I have yet to reproduce this issue again. Github issue pages have a huge number of "hidden" textareas, all of which trigger some handling from It's All Text. I'm wondering if something It's All Text is doing makes the problem much more likely to occur. And that would be consistent with longer issues (more comments) seeming to trigger this more often. Perhaps installing It's All Text and then waiting around on a large GitHub issue page (hundreds of comments) might reproduce the issue more quickly?
I left It's All Text disabled, and I still haven't reproduced this problem. Considering that it previously happened many times per day, that seems rather definitive.

Thanks for checking. Olli, could you take a look at this? I'm going on PTO for a few weeks and I won't have a chance to look at this before that. It would be good to understand what is going wrong here.
Hmm, "It's All Text" is not compatible with current beta/nightly releases. I guess I'll need to build FF56. Unfortunately the crash reports in comment 10 don't seem to have symbols

oh, the addon is up to FF49 only. But ok, I'll force enable it.
In case it helps, I'm using the version packaged in Debian's "xul-ext-itsalltext" package, version 1.9.3-1, which seems compatible with Firefox 55.
Josh, any example links where this has happened most often? So far I haven't managed to reproduce with It's All Text
Wait, are you not using Firefox from Mozilla, but Debian version of it?

Ok, can you test mozilla provided build. I don't know what all changes Debian has made to their release.
