Hello all Please someone kindly help me: I need to customize the lovely Firefox for our environment, I'm making a list to do it once and make a backup to mass restore to all PCs, so I need description of these commands to set in "about:config": 1st is there a full description list of config commands inside "about:config"? 2nd, I only have SSDs and don't want FF to cache any file on disk, need to cache them all on memory (have 64GB of 3200 MHz memory, so faster to store on RAM and save SSDs from intensive read/writes, what items shall I set in "about:config"? 3rd I found an article on howtogeek to make the privacy settings safe, setting all items here are safe? devtools.onboarding.telemetry.logged = false toolkit.telemetry.updatePing.enabled = false browser.newtabpage.activity-stream.feeds.telemetry = false browser.newtabpage.activity-stream.telemetry = false browser.ping-centre.telemetry = false toolkit.telemetry.bhrPing.enabled = false toolkit.telemetry.enabled = false toolkit.telemetry.firstShutdownPing.enabled = false toolkit.telemetry.hybridContent.enabled = false toolkit.telemetry.newProfilePing.enabled = false toolkit.telemetry.reportingpolicy.firstRun = false toolkit.telemetry.shutdownPingSender.enabled = false toolkit.telemetry.unified = false toolkit.telemetry.updatePing.enabled = false toolkit.telemetry.reportingpolicy.firstRun = false toolkit.telemetry.unified = false toolkit.telemetry.archive.enabled = false devtools.onboarding.telemetry.logged = false toolkit.telemetry.bhrPing.enabled = false datareporting.healthreport.uploadEnabled = false datareporting.policy.dataSubmissionEnabled = false datareporting.sessions.current.clean = true datareporting.healthreport.uploadEnabled = false datareporting.policy.dataSubmissionEnabled = false datareporting.sessions.current.clean = true Thanks all
