I’ll also piggyback onto Jason’s question. We might be in the same boat with the same end goal in mind. I apologize if that’s not the case.
What’s the best way to set up Firefox in a user environment where we have thousands of Windows devices with Windows user profiles that are transient in the first place (student computer labs, non-persistent VDI, etc.) so that these background auto-downloads of safe browsing databases/blocklists, GMPs, and so on aren’t taxing on WAN links? We do have some type of network caching appliances in our environment… but nothing enforcing browser traffic to use them or other proxies though. I don’t know if you call this ‘out of band’ caching. Without seeking feedback from our networking folks, I have no idea if these appliances are helping with these kinds of Firefox background downloads. Does Firefox (or any other browser for that matter) allow these kinds of background downloads to be cached by an enterprise server… in the same way that enterprise on-prem antivirus servers cache the latest defs for all clients? -- Scott Copus, Lab Systems Engineer Academic Technology | Western Kentucky University From: Enterprise [mailto:[email protected]] On Behalf Of Jason Jackson Sent: Thursday, June 28, 2018 3:22 PM To: [email protected] Subject: Re: [Mozilla Enterprise] Profile Update Intervals That’s an excellent guide, but the only one that I noticed mentioning the trigger (i.e. first interval) is the OpenH264 codec. I realized I could test this myself by opening Firefox with a blank home page on a new profile without an internet connection, then again with an internet connection, and comparing the profile folders. This is my unverified observations: · The “safebrowsing” folder was the only significant amount of data downloaded immediately. It was several files totalling 4.7MB and happens within seconds of opening Firefox for the first time. · After about 10 minutes the blocklists were downloaded, and total less than a megabyte. · After about 20 minutes the GMPs (WebRTC and Widevine) showed up, and are several megabytes. · There were other tiny things such as certs, but these are in the kilobytes. · The default new tab page will trigger downloads too, but we will be stripping it down to just “top sites” anyway. Does anyone know how to delay safebrowsing for a few minutes? ----------------------------------------- Jason Jackson Computer Systems Technician North Vancouver School District From: Enterprise [mailto:[email protected]] On Behalf Of Klaus Hartnegg Sent: June 28, 2018 10:33 AM Cc: [email protected]<mailto:[email protected]> Subject: Re: [Mozilla Enterprise] Profile Update Intervals On 28.
