User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36 Steps to reproduce: * open https://code.visualstudio.com/docs/getstarted/tips-and-tricks#vscode with Firefox 63.0a1 on Manjaro Linux 17.1.11 * For comparison, open the same web page with chrome 67 stable. * open htop in terminal, check the CPU usage of firefox and chrome * Switch from Manjaro to Ubuntu 18.04, do the same test. * Switch to Windows 10 1803, do the same test. Actual results: Firefox 63.0a1 takes about 40% cpu while chrome takes only 0.6% on both Manjaro and Ubuntu. While on Windows, Firefox is fine. I have put the screenshot of htop in the attached files. Expected results: Firefox 63.0a1 should take no more than 5% cpu, I guess.

I found the reason for the high cpu usage. It's just a [extension](https://addons.mozilla.org/en-US/firefox/addon/%E7%BF%BB%E8%AF%91%E4%BE%A0-translate-man/?src=search) causing this problem. People have the same problem should avoid it. Sorry for the bothering. I did read the documentation on Firefox Support site, but I just didn't figure out at that time. Since this problem is resolved, I will come back to the joyful Firefox. Cheers!
