Xubuntu 19.04, x86_64 system Since the upgrade to 67.0 (currently I have 67.0.1), Firefox has asked me to select a profile (of which I have only one) every time it starts and every time it opens an external link (such as the one in the e-mail to verify my e-mail address when I signed up to post here), even though I check the box to use that profile by default. I do not have a user.js file and have write permission to my prefs.js file.
