I guess the Build ID property should point to the folder in the https://ftp.mozilla.org/pub/firefox/nightly/ subtree. And there is only the folder with name 2017-05-04-10-55-26-mozilla-release-l10n which doesn’t have en-US installer (and it’s not Nightly).
So could someone point me to the right direction in this investigation.
Thanks.
Thanks. I added my About window above. It says it’s nightly but 53.0.2. Besides it allows me to install unsigned local addons which a release version doesn’t allow.
The mozregression tool doesn’t find anything Nightly with that version at the end of 2016, start of 2017. And according to the Build ID: 20170504105526 it should be (I suppose) in a folder/date 2017-05-04 but there is a 54.0a1 or something similar at that date range.
I suggest that you uninstall and reinstall your Firefox. I don’t know how you ended up with the install you have, but it’s not the build we ship for sure, and all kinds of things might be mixed in there. After uninstalling, make sure that the directory that used to have Firefox is actually gone.
Your profile is installed elsewhere on your machine, so you won’t loose your data.
