General browsing in Firefox
Even with "When you open a link in a new tab, switch to it immediately" unticked, any link I click while holding down the Control key (win 10 64bit, FF81.0.1) will result in me jumping to that tab. No biggie, but something to fix in a next release, maybe. Otherwise a great browser in combo with Duckduckgo search plug in, away from Google's hegemony. Cheers, PIM.
