A few days ago, I fired up the Firefox Development browser on my desktop, as I was working on a tutorial about CSS Grid. I may have had my regular Firefox Quantum browser open at the time. It's supposed to be connected to my Firefox Synch account, which has been doing a bang up job of synching my laptop browser with my desktop browser.

When I exited out of the browsers and fired up the regular Firefox Quantum browser, I found that it had gone to a default "factory settings" look, but also had my recent browsing history from my Developer session. I tried to synch with the Firefox Synch account. That didn't restore my regular set up, Restarting the browser also didn't reset anything.

Hi, yes they do share and it should be told .

https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data See if you have anything in your Standard version Profile left of use or if there is a 2nd Profile made.

I have 2 Profiles in here : C:\Users\(REPLACE NAME)\AppData\Roaming\Mozilla\Firefox\Profiles 1 is Standard, 1 is Developer

Note that you should always make sure to start a Firefox version with a desktop shortcut that specifies the profile folder in the target line (-P "<profile name>") if you use multiple Firefox versions to avoid profiles getting corrupted.
