User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:54.0) Gecko/20100101 Firefox/54.0
Build ID: 20170628075643

Steps to reproduce:

This link causes FF (54.0.1) to hang and consume all memory fairly quickly.  I came across it by chance.  I do not know much about the site, nor what may be causing the problem.

Actual results:

my machine has 32GB and all was consumed within 5 minutes or so


Expected results:

Chrome does not seem to have the problem
Hi Dave,

I tested this issue with FF Release 54.0.1 on Win 10 x86 and could not reproduce it.

Could you please capture a gecko profile using the steps from here: https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Reporting_a_Performance_Problem

Please let us know the results.

Thank you!

OK, I am sorry but I want to keep this machine 'clean' so I won't be installing nightly or add-ons.  But if there is other info that I can extract from my setup, please specify.
I confirm that the problem still occurs.

Could you please try to Run Firefox in Safe mode and see if you encounter the same behavior?

Sure: in safe mode the problem still occurs, but does not seem to consume memory quite so quickly. Nevertheless FF consumed 8GB in 30 mins and no sign of stopping.  Did I say before that FF is *unresponsive* all the while (after clicking that link) ?

Are you able to update to a newer version of Firefox? Like current release (55)? Or do you need to stay on 54?

Sorry for my slow reply  - no, I am now on ESR 52 because I don't want my addons to break.  When that happens (silly decision by firefox) I will review which browser to use. A shame after 15 years.

Meanwhile ... well this is exciting ... I tried my 'failing' link on ESR 52 and it FAILS here too, even with Firefox restarted in SAFE mode. Memory gets gobbled up and Firefox goes unresponsive.  I had to kill it.

So maybe I can help further if you have diagnostic tools that work with ESR 52.

Hi Dave,

When this happens, could you please enter the address "about:memory?verbose" in the address bar and attach (using the "Attach File" link above) the output here.

Thanks
