Sync pulled in settings from a government managed computer into my personal computer. HOW DO i DISABLE THIS AT HOME?
Logged into Sync on my work computer to share website saved links, but it pushed the managed computer settings for the browser back to my personal computer. Logging out of my personal computer does not allow me to change back to self managed setting at home. How do I reset the browser to remove the work computer settings from my personal computers?
Yes, that is the manner in which Sync works; selected data types per device are synchronized on both directions to & from the Sync server when a 'new device' is connected to Sync. Then when other devices open Firefox the synchronization process continues to 'that device'. Other than selected data types and on/off there are no "user controls" with Sync. The undo for Sync for a particular device was removed from Firefox a few versions in the past; evidently it was a temporarily added feature for Sync (maybe for 'testing' and was enabled for just a few versions) and I guess that "it didn't cut the mustard", so it got axed due to complaints and at least one Bugzilla report.
There is no "reset" for user saved data beyond creating a new Profile and starting from scratch. The "Refresh" procedure would save specific user data (bookmarks and logins data) to a "refreshed Profile". All user customizations would be gone.
As far as bookmark backups goes, Firefox does save 15 backups of the users bookmarks (only); restoring a bookmarkbackup file would delete saved browsing history, AFAIK. That's not something I have ever had the need to do; restoring a bookmarksbackup.
