Hi, If have 1 program and it gets updated it's updated regardless if have 1 or more Profiles.

You can use the Developer Edition which is a Beta and always will be updating to newer version every other couple of days in Compatibility mode with a older version of Firefox.

It shares your bookmarks and more. So always :

Please let us know if this solved your issue or if need further assistance.

Note: Windows users should download the ActiveX for Internet Explorer. and the plugin for Plugin-based browsers (like Firefox).

Note: Windows 8 and Windows 10 have built-in flash players and Adobe will cause a conflict. Install the plugin only. Not the ActiveX.

You would have to install the two different Firefox versions you want to use via a custom install in their own Firefox program folder to have them distinct.

Firefox 52.7.3 ESR:

Firefox 59.0.2 release:

• https://www.mozilla.org/en-US/firefox/all/
• https://www.mozilla.org/en-US/firefox/59.0.2/releasenotes/

You need to make sure to start each version with its own profile. Then you can set the update settings of each version like you desire in Options/Preferences. Keep in mind that 64-bit Firefox versions only support the Shockwave Flash plugin.
