It does not sync, I tried everything I added our corporate certificate, I can browse but It does not sync. All my other devices are ok.

-Added corp certificate and verified: http://ip.zscaler.com/ -use system proxy settings

I attached about:sync-log

update: it synced when I changed the Firefox network settings to :"Auto-detect proxy settings for this network". But then I cannot open any website.

I switched back to "Use system proxy settings", it opens everything but it wouldn't sync.

When I typed our proxy ip in 'Manual proxy configuration', it wouldn't sync and it wouldn't open any page

Happens to me too, my company uses Zscaler for proxy.

I think this started to fail around the same time I noticed firefox started to display the "You must log in to this network before you can access the internet" banner. (attache screen shot)


I don't know if FF Sync rotates logs, but the earliest failure on my machine was on 10/27/2019.


I'm adding a smaller log file to aid others when searching for the same issue.
