I have tested your issue on latest Nightly build and could not reproduce it. I have opened multiple tabs but the memory usage is in range. From what i can see, e10s is not enabled on your browser.

Can you please retest this using latest Nightly build (https://nightly.mozilla.org/) and report back the results ? When doing this, please use a new clean Firefox profile, maybe even safe mode, to eliminate custom settings as a possible cause (https://goo.gl/AR5o9d).

I have also tested the same issue with Firefox Nightly 56.0a1, and it is happening again. Already attached the screenshot with Three tabs, please the attachment- firefox-nightly.JPG

Were you able to reproduce in safe mode [1]? Can you also provide the list of extension you're using from about:support?

Dear developers of Firefox,

I have 55.* version of Firefox at work and at home
At work i have Windows 7 OS, at home the Ubuntu 16.04 LTE
I have my own synced profile. I don't have problem with syncing...

In both OSes i regulary and every day i see the situation when after few work time (may be even after 1-5 minutes) of Firefox i see the CPU 100% of Firefox and the Firefox hangs up after... Only one way i have for repairing of this: "killall -HUP firefox" command at Ubuntu and "End Task" in Windows.

In both cases i have turned on option about "report health" and about "reports to Mozilla". I know about the page "about:crashes" and regulary to see there. The main problem is there: this hangings up cases are not generated there. When i killed the Firefox and restarted its i didn't see fresh some reports in "about:crashes". I tried to tun on safe mode too. In safe mode the Firefox has same buggy behaviour - after some minutes it starts to eat 100% of CPU and no responding after... And again in "about:crashes" doesn't have there any fresh generated reports (about:crashes sometime has reports there which were created by other situation - may be by like "segmentation faults" errors).

I conclude that this "CPU bug" is not reported to you in many user cases! And i conclude that this is global problem (some OSes) not related with hardware and plugins.

I don't know how to report about this to you. I love your browser but your last version (55.0.2 & 55.0.3) are very very buggy. This is very annoying!

Best regards, Alexey

Alexey, thank you for the crash reports. This bug is closed, can you file a new bug for your issue and CC me on it? It looks like you might have a sqlite issue. You could try running in safe mode [1] to see if you still have problems and if that fixes things a Firefox refresh [2] might help.

Let's followup in the new bug though.
