FireFTP has suddenly decided to freeze on opening - with the message: "A script on this page may be busy, or it may have stopped responding. You can open the script in the debugger, or let the script continue. Script: chrome://fireftp/content/js/local/localTree.js:301" I'm running the latest FF and FireFTP, and even after uninstalling and reinstalling FF and FireFTP, I still get the message. This is similar to this two-year-old issue: https://support.mozilla.org/en-US/questions/911978 I cleaned out config or preferences folders for fireFTP between re-installs. Can anyone shed light, please? I love it and miss it.
