Thanks for writing a bug report but it's not very useful. We need some steps to reproduce the issue (URL e.g.) and a crash report you can find in about:crashes.

Without more details, this bug report will be closed as incomplete.

I can't reproduce it as it arrives at random
Hi bugzzz,

I see from your User Agent that you use Firefox 45.0, is the ESR version or the release version? You can verify this in about Firefox by clicking the menu, then the question mark and choose "About Firefox" option.

If is Firefox release version, can you please update the browser to the latest (49.0.2) version and see if this issue is still reproducible? You can download it from here:

If is still reproducible it will be helpful if you can provide a crash report like Loic suggested in comment 1.

I changed the version to 49.0.2 and have to wait for the bug to happen.
Hi bugzzzz,

Is this still reproducible on your end using Firefox 49.0.2? If is still reproducible, can you please provide a crash report? 
However, Firefox 50.0 just landed and you can update your browser.

Hi bugzzz,

Thanks for the crash report. I have tried to reproduce this issue on Ubuntu 15.04 but the browser didn't crashd. I have also installed the add-ons provided in "about:support" attached file in comment 7, but still the browser didn't crashed.

It will be very helpful if you can find some steps to reproduce. Maybe a website you've visited when the browser crashed.

However, based on your provided crash report I am assigning a component to this issue in order to involve the development team and get an opinion on this.
Crash Signature: [@ js::GCMarker::markAndScan<T> ]
Component: Untriaged → JavaScript: GC
Product: Firefox → Core

bp-e9ce4a67-4b14-433f-870e-8610a2161120 appears to be the only crash report submitted with the reporter's email address, so it's unclear what "regularly" means. Without more info this is incomplete

I haven't had a crash since January.  Now, two days in a row, I get two, and they both point here.

They both happened while perusing one feed,'s RSS feed:

in The Old Reader:

I reload after the crash, and all seems to be fine.  I'll make the comment that this feed always brings my speed way down, always causing Firefox to go 25% (quadcore CPU), and it has to be javascript that is making Firefox go nuts.  Not that I know how to read the HTML generated, since it's all generated by anyway.

I don't know if this is enough to open this back up or not, but to make it repeatable, I'd create a new TOR account (a free one should work, just as well), add the feed, wait a few days to build some posts up, and then, just start scrolling down...
