autoscout24 is a website which seems to not be thoroughly tested in Firefox in general.

It makes the Browser unusable and makes it impossible to remote debug and diagnose
and eventually it after a while it just crash the browser.

I tried to record a more meaningful profile but I failed. The site is crashing the browser.

It takes sometimes 10 minutes before crashing.

I'm moving this core performance, so we can try to discover why it is crashing the full browser.
My crashes are on a Pixel 2 with Firefox Nightly latest version.

Let me try to reproduce this and capture more profiles.

Comment 3

[Andrew Creskey [:acreskey]]

Locally, on a Pixel 2 with the latest Fenix Nightly (firefox96) this site is loading quite reasonably for me.
Using the url from comment 1,
https://www.autoscout24.com/lst/renault/express?sort=standard&desc=0&ustate=N%2CU&size=20&page=1&fregfrom=1991&atype=C&

There are a couple of seconds of jank during the load. They are caused by longer running JS scripts.
https://share.firefox.dev/3GpqBPv

The site is not crashing for me after extended use.

Maybe someone who can reproduce the crash can capture logs through adb?

Comment 4

[Alex Thayer [:alexical] (she/her)]

Hey Karl - does this perform worse for you on Firefox than on Chrome? It performs poorly for me on both browsers on Android. The crash is a problem (though I can't reproduce this), but I don't think this belongs in performance unless it's perceivably worse for us than it is for Chrome.

Comment 5

[Bas Schouten (:bas.schouten)]

Crashes do not belong in Core::Performance. Closing this bug as wfm since we don't seem to be able to reproduce the crash.
