Hi. I have two versions of firefox on my Win 7 PC. Both are portable. First is ESR 52.3 with alot of enterprise tweaks, and some features locked. The second is Quantum portable. I have it set so i can launch and run either alone, or both in parallel. The only problem i run iinto is when i try to click a link in an email (outlook 2016), it defaults to the ESR 52.3 version, if that is open, and if its not open, i get an error message, "firefox cannot find your profile, its missing.." I would like to set it so that clicking links within an email will open the relevant pages in newer, Quantum firefox. I tried setting the Quantum version options to "this is my default browser" but it did not help. Thanks
