i'm getting this in the browser console when Firefox 59.0.2 on Fedora is syncing:

1526076217390 addons.xpi WARN Failed to start download for addon https://addons.mozilla.org/firefox/downloads/file/951074/session_sync-3.0.2-an+fx-linux.xpi?src=sync: [Exception...

I am the owner of the my home directory and permissions on mozilla directory tree are 755.

It appears that this error is also affecting regular downloads from all websites. I have treid creating a new, empty profile and still get the error.

All i get is this message in a popup:

"[null] could not be saved, because an unknown error occurred.

Try saving to a different location."

Did you get a segmentation fault? and as a freebsd user im embarrassed to ask what 755 mod is, what access level is this, isnt 777 a global rwx ?

more options

no segmentation fault. it just silently stops. it doesn't sync anything (i'm only syncing prefs and add-ons) but it doesn't provide any information that it didn't sync.

755 is rwx for user, rx for group and rx for others

would you come to #sumo on irc.mozilla.org tomorrow around 11am EST, i think i can better assist if we talk live.

if you are awake now, have you tried compiling the source code in a directory in ~/ ?
