New clear profile every time after Firefox update

more options

Hello.

In organization we like to use Firefox as default browser. But we have a every day problem with profiles.

After update, Firefox create new profile and not copy user data to it. So user lost hes tabs, extensions, history and e.t.c. We can see two or more profiles for one user.

For example user logon to computer with Firefox version 68.0.1. Firefox automatically update to 68.0.2, and user now have new profile without custom data.

profiles.ini looks like:

[Install308046B0AF4A39CB] Default=Profiles/6qa5a710.default-release Locked=1

[Profile1] Name=default-release IsRelative=1 Path=Profiles/6qa5a710.default-release

[Profile0] Name=default IsRelative=1 Path=Profiles/xu3ic03g.default-1561039332923 Default=1

[General] StartWithLastProfile=1 Version=2

We create powershell script for workaround issue. Script copy files from privies profile: $profileCurrent\*.sqlite" $profileCurrent\sessionstore.jsonlz4" $profileCurrent\extensions\*.*" $profileCurrent\*.json"

You mast know that in organization we user roaming profile and ue-v, so users can logon on any computer. Some computers can be with older Firefox version like 68.0.1 or new one like 68.0.2.

Please help find solution for this issues. Can Firefox account help with this? Or we mast create some more clever script?

Thank you.

Do`s it help me? -allow-downgrade

Firefox 67's Downgrade Protection prevents accidentally starting Firefox in a profile running a later version of Firefox. Depending on changes between the two versions, some files in a profile may not be downwards compatible. Adding this option bypasses Downgrade Protection.

The new upgrade should use the existing profile. Not create a new one unless something goes wrong.

Are you saying the original profile is not there, or not accessed?


Not there) Look on your desktop. Do you see a folder called; Old Firefox? Look inside. Look for the folder with the latest creation date.

Not accessed) You may have a corrupt profiles.ini file. Close Firefox. Open your file browser to this hidden location:

  • Mac: *~/Library/Application Support/Firefox/
  • Linux: *~/.mozilla/firefox/
  • Windows: %AppData%\Mozilla\Firefox\
  • *C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\

Locate the profiles.ini file. Then rename or delete it.

Firefox should create a new profile.

Safest would be to only use a profile with the preferred .default-release file extension because in some cases Firefox prefers such a profile. A profile with a time stamp appended (I see: 1561039332923) is created as the result of a refresh.

Installs.ini stores data that is used to lock a profile against a specific installation folder.

It seems that the problem occurs if a user with a new profile starts Firefox with an older version.

So user select create new profile.

Who force update before start up Firefox?

Hmmm, -allow-downgrade works perfect! :)

Also I want to reconfigure UE-V template and sync only this files:

$profileCurrent\*.sqlite" $profileCurrent\*.jsonlz4 $profileCurrent\extensions\*.* $profileCurrent\*.json"

That's all, nothing else. What do you think about this?
