I know a lot of work has been done, and some patches added recently to help with this crashing, so wanted to see how this bug fits in.

Hello! In order to reproduce the issue could you provide some answers to the following questions?

1. Could you provide some steps on how you managed to reproduce the crash?
2. Does this issue also occur in safe mode with the add-ons disabled?

Thank you

I tried to reproduce this issue using the above mentioned add-ons but without success, I switched the Status to NEW by accident, this issue is still unconfirmed by the QA team, maybe someone from the dev team can move it back to new because of the large number of reports? Maybe if we can get a reduced case it might help us reproduce this crash on our side.

Wayne can you take a look at this?

Thank you!

I don't see this as being a 64bit issue, so -64bit.

I don't have cycles to look at it, but there are many other crash reports with OOM | small, including those reported by the user, like bug 1673778

I've encountered this crash today, on RC 89.1.0 build with Samsung Galaxy Tab A6 (Android 5.1.1). The scenario was:

1. I had about 14 tabs opened.
2. uBlock Origin installed and enabled.
3. Opened a yelp.com page that the uBlock blocked: moz-extension://591d5e78-ce3b-4449-9613-6b1ed269bddd/document-blocked.html?details=%7B%22url%22%3A%22https%3A%2F%2Fapp.adjust.com%2F9ib7e21%3Fadgroup%3Dsearch.fs_second_page%257Cforce_click.all_sessions%26campaign%3Dmobile.app_pitch.bunsen.growth_acq_m_site_experiment_slots%26creative%3Dreferrer%253Ayelp%26deeplink%3Dhttps%253A%252F%252Fm.yelp.com%252Fsearch%253Fcan_modify_open_behavior%253DTrue%26engagement_type%3Dfallback_click%26label%3DFB42DB4256260686%252CNone%252C5e4003fb9915f722%22%2C%22hn%22%3A%22app.adjust.com%22%2C%22dn%22%3A%22adjust.com%22%2C%22fs%22%3A%22%7C%7Cadjust.com%5E%22%7D
4. Tapped on "Go back" button from the page from step 3, and Fenix crashed.

I can't say, as I do not recall it happening the same since. There are many similar crashes, but it is hard to tell the difference. I am doing this as a volunteer, not as primary job, so can't put a lot of time into researching these. If there is something specific to try, please let me know. Even disabling add-ons would be fruitless if it doesn't reproduce with them.

Can confirm this is also happening on firefox 92 now

But your crash doesn't have the same stack
