Constant Crashes on GrapheneOS

[secretmango]

When visiting a website I get these soft crashes. Once it works normally, then freezes, after that I constantly get "Mull does not react" messages. They only give logs on the first opening.

This potentially indicates a GPU hang.

How often? Just some websites? or many websites? How many extensions do you have?

[secretmango]

I have this issue every few days.

I have a looot of extensions and should probably try to reproduce without them :/

As it is happening so rarely, this is pretty annoying but I can try.

Extensions:

UBlock Origin
NoScript
Firefox Translate
Audiocontext Fingerprint Defender
Canvas Fingerprint Defender
Font Fingerprint Defender
WebGL fingeprint defender
Bypass Paywalls Clean (D)
Cookie Autodelete
Download all images
IPvFoo
"Enable Read mode"
LibRedirect
Offline QR Code
SingleFile
Tomato Clock
Wayback machine
Old Reddit Redirect
ETag Stoppa

I will try to remove the nonessential ones first.

[secretmango]

I was able to reproduce without any addons.

Specifically using the website bike-discount.de

When adding things to the cart (writing cookies?) It constantly crashed.

I have 2 logs, can I send them to you personally? Not sure if they include sensitive details

[SkewedZeppelin]

Please try to reproduce on official Firefox for Android and report to Mozilla here if it happens: https://bugzilla.mozilla.org/home

[secretmango]

True, I will do that.

I sent the crash logs every time, where do they end up?

I tried on latest Firefox, opened a bunch of tabs, used the same website, was not able to reproduce at all.

Even did the Web Basemark, it just doesnt crash.

[SkewedZeppelin]

I sent the crash logs every time, where do they end up?

In Mull? They don't go anywhere.

[secretmango]

Lol thats not good.

Anyways here are some logs.

Mull-crash-no-addons.txt

An older log

Mull log e5211f169708.txt

These were generated by GrapheneOS/Android.

I am currently unable to reproduce on the same site. This may be a memory leak or oom issue. I closed all my previous apps before.

Maybe there is a memory management issue and firefox crashes. I have 91 open tabs but they should not be in RAM.

Maybe this happens with over 100 tabs?

Did you wrongly try to enable Fission via about:config?
