Hi pjules.

The preferences in the Configuration Editor for Firefox you should look for are browser.sessionstore.restore_on_demand and browser.sessionstore.restore_pinned_tabs_on_demand.

However be careful when changing them. The configuration editor is a dangerous place in general, unless you really know it. Also when you have many tabs open, restoring the previous session and loading all the tabs may take a while.

Hello - I referenced this article: http://mzl.la/1TQpHlj in trying to solve this problem, and did not find it to address this issue. I don't know if anyone has asked this question coherently enough - I cannot find another area in support where this is answered. When I open Firefox (Quantum), I do see all the tabs from my prior session, as I've selected in General settings. However, none of these tabs reloads until selected, unless I right-click a tab and select Reload All Tabs from the context menu. Is there a way to enable every tab restored to load in the background on launch, so that the first time I select a particular tab, I don't need to wait for it to load? I'm switching all my devices from Chrome to Firefox today and I really hope I can find a way to enable this behavior. Thanks, pjules

Thanks Michael! This worked for me by marking both of these values "false." I'm sure this would make it problematic / impractical in terms of loading for folks with many tabs open; I'm pretty light as that goes, with usually 5 or 6 open, and only rarely higher, maxing out around 20.

For background, I usually leave a few articles / Amazon / desktop texting sites open, and routinely switch between a couple gmail accounts, and those are the ones that I wanted to ensure would load in the background so they were ready for me as soon as I switched.

Again, thanks!
