Manuel, you have created a wonderful addon, thank you! I have a suggestion for development. Manuel, please add the ability to change the icon and text in the context menu in the add-on settings interface. Changing the text is needed to adapt to the localization of my country.
To adapt for your localization, the proper way would be to do a full addon translation. https://lusito.github.io/web-ext-translator/?gh=https://github.com/M-Reimer/undoclosetab/ Would be great if you could do a translation and then use the "Submit changes to the developers" button in this online translation tool (github account required).
