Firefox on my 2018 MacBook Pro started having issues downloading all file types after I disconnected Dropbox sync and backup. Each time I try to download a file, a failed message is displayed below the file name and type. The browser was using the downloads folder that was synced with Dropbox. After disconnecting Dropbox, I tried changing the downloads location, but the "Choose" button does not display a window. The result is the same whether the ''Always ask you where to save files'' is checked or not. I have gone through the following steps trying to resolve this issue with no success. # I have reset/cleared any configuration setting found using '''about:config''' and '''browser.download'''. # I have launched Firefox in troubleshoot mode and tested downloads with no resolution. # I have uninstalled Firefox and installed a fresh copy from mozilla.org with no resolution. # I have set the downloads folder in Safari, but this did not provide a resolution. Downloads work as expected in Brave and Safari. The current downloads location is the '''Downloads''' directory on my '''iCloud Drive'''. The second screenshot with the error attached in still referencing the Dropbox-connected Downloads folder. No other browsers are using this folder and the Dropbox app has been completely removed from my laptop. I use Firefox for web development and need to be able to download various files throughout the day, so this has become very frustrating. Any help is greatly appreciated. Cheers,
