We have several users whose AppData\Roaming\Mozilla\Firefox\Profiles\xxxxx.default\storage\default folder has grown to over 1 GB. Is there a way to limit the size of this folder. These users are in a VDI environment and these files get merged into their VDI desktop which greatly increases their logon times.

I'm not aware of a way to do this in Firefox. You would have to set the quota in the Windows OS settings and possibly cleanup this folder. Storage is part of the cookies, but you would probably have to remove all cookies to include local storage or do this manually in "Options/Preferences -> Privacy & Security -> Clear Data or Manage Data".

I think it might be helpful to look in more detail at where the big files are. For example, there are folders for:

  • websites -- folder names typically start with http
  • extensions -- folder names typically start with moz-extension
  • built-in pages -- folder names typically start with about

Within the folders, the idb folder indicates database storage. Some extensions may build very large databases and you might have a policy about such extensions.

Most of it is in built-in pages. Below is one example.

about+home - 478 MB about+new - 705 MB moz-safe-about+home - 364 MB
