Addons don't works

[bigkrp]

I tried use addons WindowSizer and Window Resizer and both don't work.

Here errors:

JavaScript error: resource://gre/modules/ExtensionUtils.jsm, line 0: Error: An unexpected error occurred
JavaScript error: resource://gre/modules/ExtensionUtils.jsm, line 0: Error: An unexpected error occurred
JavaScript error: resource://gre/modules/XULStore.jsm, line 66: Error: Can't find profile directory.
JavaScript error: resource://gre/modules/XULStore.jsm, line 66: Error: Can't find profile directory.

And at start FirerfoxDevEdition was some errors:

JavaScript error: resource://gre/modules/XULStore.jsm, line 66: Error: Can't find profile directory.

Did you try using them on the Official stable Flatpak? The Firefox from your distro's repo?
