User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20160407164938

Steps to reproduce:

Going to https://zbigz.com/ with Firefox causes huge memory usage spikes. Does not do this in  Opera. Tried another Firefox instance on another computer, same issue. I made a video to demonstrate:
https://dl.dropboxusercontent.com/u/63231818/firefoxbug.mp4



Actual results:

Firefox allocates huge amounts of memory, causing the Windows system to slow down.


Expected results:

A web page should not be able to cause Firefox to do this.

Could you test:

1) in safe mode:
https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode

2) with a fresh profile:
https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles

Same memory use?

Hi.

Still does it in safe mode with a brand new profile:

https://dl.dropboxusercontent.com/u/63231818/firefoxbug2.mp4

Seems to do it when you type.

Regression from 41. We are unlikely to fix this in 46 but could still take a patch on other branches.

I took a look at this. The website is making a 40000x40000 box shadow along with a 40000x40000 border-radius. At least on my machines, we can't create a surface that big and don't draw the box shadow as well. Safari does this also.

Chrome / Edge do something special to draw box shadows along rounded rects, which I'm not sure how they do this. I also took a look at ESR 38 and it should suffer the same problem. I'm not sure this is a real regression.

We should stop tracking.

The site is using this gigantic box-shadow/border-radius to achieve a kind of neat design element: https://cloudup.com/cJ4fxYCALPN.

That said, I think we should just ask them to consider other ways, such as SVG or a static graphic given that Firefox and Safari struggle with it.

Their last tweet is on  9 nov. 2015 and before that may 2015, with no interactions with users. So I guess not a good fit for contacting them.

Zbigz has so many bugs not only this firefox memory leak. Hence I recommend you to use zbigz alternative sites https://techspree.net/5-best-zbigz-alternatives-june-2013/
