I'm using FFQ on my MacBook Pro - OS X machine running High Sierra, and when I open a webpage in a new tab (background or not), my CPU usage spikes through the roof and the entire computers slows way down. I watched the activity monitor to see what was going and most of the processes are idling kind of high (about 22%), but there's one process that is definitely the one causing issues. On a new tab being opened, the "Firefox Developer EditionCP Web Content" process spikes as high as 115%.

Is there a way to fix this, or at least make it not-as-bad? I love FFQ on my Windows machine, but it's making my Mac nearly unusable.

i, maybe need to swap what your doing on each system.

Windows instructions as is all I have, due to lack of Support making documents compatible to any version. : To be Checked and turned off unless needed for accessibility : Please : go to the Firefox 3 Bar Menu --> Options --> Privacy & Security panel and under Permissions check (put a tick in the box) the setting to Prevent Accessibility Services from accessing your browser.

Multi-Processor Support : Go to the 3 Bar Menu then Options --> General --> Performance and untick everything. change the recommended size lower then see how it runs. Note: 1 = No Multiprocessor = slow again. Try 2 Restart Firefox after making these changes please. Note : Hardware Acceleration is for Video Card, Monitor to see if remain off or to turn back on.

Only Disable as last resort.

Multi-processor Can completely disable it this way in about:config : dom.ipc.processCount set to 1 browser.tabs.remote.autostart = false browser.tabs.remote.autostart.2 = false
