Hello Will

Thanks for your quick reply to my mail. Much appreciated down here.

Will ask ops people to give it a try and see what happen. Will also find out on which operating system(s) Windows7 / Windows10 problems are reported as we are also in the Difficult Journey from Seven to Ten ...

Will let you know about results

Bien Cordialement / Best Regards

We're currently migrating to Windows 10, and we've noticed this behaviour on the Windows 10 machines.  If you set the Firefox Network Settings to "Auto-detect", it seems to solve the issue.  The problem obviously remains, because that's actually what the Windows 10 system settings are, but we haven't had the spare resource to investigate if the issue is with Windows 10, our proxy, or Firefox.

Regards

Will

Subject: [Mozilla Enterprise] [FF ESR 60.2.0] very frequent "Hmm. We're having trouble finding that site" warning message

Hello,

We are in the process of rolling out the 60.2.0 esr (64 bits) version of FF on our  +/- 100.000 workstations.
To do so we have used a combination of a SCCM package and GPO thanks to the FF ESR ADMX provided. As you can imagine this is our first experience with FF ESR GPO

So far we are observing a PILOT Phase and have an installed base of a couple thousands of  60.2.0esr (64 bits) and we have been asked to slow down because users report they "quite often" get this warning message when they have "multiple" FF tabs opened at the same time.
This is something we never experienced or at least we never experienced without being able to explain it before while using FF ESR 52.x or earlier releases.
Our proxy settings have not changed either.
This does not happen when users only have a couple Tabs opened at the same time.

Does this ring a bell to you ?
Any idea on how we should conduct troubleshooting sessions to try to establish the root cause of this ? Anything we can try to log in the software program ?

Thanks a lot
