With version 2.0.7, the name of the file to be saved in the firefox profile was stylish.sqlite. With version 3, the stylish.sqlite file is no longer recognized (the import does not take it into account). What is the name of the file?
Another point: when I click on "Save installed styles", firefox opens a window with a different name each time and without extension (xzZrb2e5 or +u+RoxP_ or something else). Is this normal?
