Disable addonlists_show_addon_version_number.css by default for FF60

Disable addonlists_show_addon_version_number.css by default as it doesn't work anymore in FF60 and prevents the addonlist to be displayed

Maybe you also disable location bars classic autocomplete popup from #43
I don't use it and couldn't find it. Don't know if it has negative impact if it stays activated in FF60.

The version number in add-on lists works fine up to Firefox 62 for me.
Are you using the latest files from this project?

I excluded the two lined autocomplete popup option from default enabled settings a while ago, because it was incompatible to popups search features. It still works fine, if you ignore the search stuff.

Please run tests with projects latest files on a clean browser profile before assuming they don't work. No need for an immediate commit. ;-)

Sorry, I'll retest again.
Everytime I enable addonlists_show_addon_version_number.css I got an empty "list". Maybe something went wrong with my update.

And I just made the PR for you to have an easy one-click solution. Accept or deny :-)
I'm not angry for denial if there is a hint why.

Can you confirm that you are using the latest files?

[stonecrusher]

Latest, yes.
But after some debugging I've found out xml folder wasn't recopied properly (folder was there but files not copied because of different fileextension).
My fault.
