Describe the bug
Classic 2020.03.1 [edit: also affects 2020-04 through 2020-06] has not automatically updated itself to the latest 2020.05, and is now months out of date. The "about Waterfox" window says "Waterfox is up to date".
To Reproduce

Expected behavior
It should update to and/or show availability of the latest version, 2020.05
My configuration
theres also been issues since that month where the update.mar fails to update the installation on the next start leading to waterfox not loading at all.
I manually updated to 2020.05. I just saw that 2020.06 came out more than a week ago, but it's still saying it's "up to date". This is worrisome, there are going to be a lot of people with outdated and potentially insecure installations of Waterfox.
Seems that it's still not working, 2020.06 says "up to date", but 2020.07 was released almost a week ago.
This has been fixed. 2020.07.2 is now available, auto-updates being pushed out tomorrow :-)
