I find it very frustrating that firefox quantum no longer allows the add-on Change Bookmark Recent Folder List Length to be used.
Is there some method to increase the folder location drop down list

With the release of Firefox Quantum (Firefox 56) all extensions that did not use the Webextensions API were discontinued. This provided a number of performance and security improvements, plus extensions are now much easier for developers to create and maintain.
The people who answer questions here, for the most part, are other Firefox users volunteering their time (like me), not Mozilla employees or Firefox developers.
