Can a user force multiprocessing OFF in Firefox Quantum?

I'd like to see if this helps with the slowness experienced on some pages when Quantum is used together with the NVDA screen reader. (See https://www.nvaccess.org/post/in-process-halloween-2017-edition/ regarding that problem).

Quantum+NVDA is so slow with some pages that I had to kill some other processes first, in order to be able to kill the Firefox process tree.

Thanks.

P.S. - I tried to "Automatically add" my "Troubleshooting Information" but that gave me a "We're sorry, but we can't find what you're looking for." error. URL: https://addons.mozilla.org/firefox/downloads/latest/troubleshooter/addon-426841-latest.xpi. See attached screenshot.) Perhaps that's not compatible with Quantum.

To disable e10s/multiprocess go to about:config by typing it in your URL bar. Search for browser.tabs.remote.autostart using the search box on about:config. There may be multiple results. Set them all to false and restart the browser.

Thanks. Mkll. As verified by Task Manager, that successfully causes FF 57 to work in single process mode. And so far, NVDA seems to be behaving much better with the change.

Thank you.
