Rated 5 out of 5 stars
This goes for both, Firefox, and Thunderbird 54 beta.
In the Add-Ons Manager - Extensions:
entering an add-on in the search box, e.g. enigmail
There are multiple hits in the search results, and for each hit the 'Last Updated' column shows 'January 1, 1970'.
This doesn't happen when disabling the add-on.
Otherwise a great add-on.
I'm still seeing this with a new profile. And it also happens with FF53.
Success. Using 1.4.1b1 the problem is gone. Tested w/ FF 54.0b9 on both, Linux and Windows.
Thanks for the quick fix.
this looks like a server issue with Mozilla servers. Time stamps are correct in my tests.
Please test on a new Firefox/Thunderbird profile.
This happens on Linux, but not on Windows. Not sure why yet. I will look into it.
Install and test this beta:
Make sure you restart after installing 1.4.1b1, even if this is a restartless add-on.
