Hi nokudoku, 
Thanks for reporting this! I tried your steps, but I cannot reproduce this issue with FF 54 (e10s enabled) on Win 10. Do you think you could try to see how it goes with all addons disabled or with a new firefox profile  (referring to [1])? Thank you again.

Hi! So far it seems that after doing a cold reboot the issue for now seems to have been faded away.

Thanks nokudoku for checking this again. Per comment 3, I am going to close this as WFM. Do feel free to reopen if you still see this.
