High CPU and memory usage with latest Firefox
User Agent: Mozilla/5.0 (Windows NT 6.3; rv:54.0) Gecko/20100101 Firefox/54.0 Build ID: 20170628075643 Steps to reproduce: Browsing with latest Firefox (version 54), 5 to 7 tabs opened. Actual results: High CPU and memory usage with Firefox, due to this machine is became hang stage. Expected results: Normal browsing need to be happened.
User Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:56.0) Gecko/20100101 Firefox/56.0 Build ID: 20170720030203 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

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

Hi! I made some crashes by hands (crashfirefox.exe) in Windows 7 and in Unix through kill -ABRT What are the symptoms? In random moments the Firefox v56.* has only-one core CPU 100% eating.

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  to see if you still have problems and if that fixes things a Firefox refresh  might help. Let's followup in the new bug though.  https://support.mozilla.org/kb/troubleshoot-and-diagnose-firefox-problems#w_3-restart-firefox-in-safe-mode  https://support.mozilla.org/kb/refresh-firefox-reset-add-ons-and-settings
