Thanks for your quick response.

For this run here, I only had Gnome + Terminal (bash+top only) + Firefox (blogger only) running.

At first, on loading the page, firefox-bin went to about 50%, then this:

  PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
 8691 root 20 0 70908 14m 6932 R 78.8 3.8 0:11.12 Xorg
 9034 fr 20 0 174m 47m 23m S 7.6 12.6 0:08.12 firefox-bin

Then Xorg started going from about 50% to about 90% while firefox-bin remained constant:

  PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
 8691 root 20 0 71644 14m 7184 R 89.8 3.9 0:37.35 Xorg
 9034 fr 20 0 175m 48m 23m S 8.0 12.8 0:12.59 firefox-bin

This is with https://www.blogger.com/start on the visible tab. As soon as I open another tab in Firefox, e.g. by typing Ctrl-T to open a new tab, the CPU is immediately freed from the heavy Xorg load and I can work normally:

  PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
 9034 fr 20 0 176m 49m 23m S 8.0 13.1 0:35.62 firefox-bin
 8691 root 20 0 71900 15m 7352 S 4.0 4.0 1:42.45 Xorg
