Rated 3 out of 5 stars

Today FireFTP "lost" or hid all my connections/accounts.

Firefox 15.0.1.
I tried FireFTP 2.0.7, 2.0.6, 2.0.5 with uninstal between versions.
All my accounts are still invisible.
Any options other than further downgrading and waiting for updates?

This review is for a previous version of the add-on (2.0.7.1-signed). 

Sorry that you've run into this issue. The new version of FireFTP is doing migration of an old account format to a new one. Unfortunately, there are some illegal characters that make it difficult to upgrade to the new format that Mozilla now requires. (specifically, the combination of trying to convert international characters and the '%' character creates problems).

If 2.0.7 isn't working for you, you can try the following:
- find your profile folder, here are instructions: http://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data (if you're on a Mac it'll be under: ~/Library/Application Support/Firefox/Profiles)
- find the file in your profile folder called fireFTPsites.dat
- remove the '%' characters found in the file.
- install version 2.0.7 and readd the % characters back in later as needed. (not directly into the file, but via the regular FireFTP interface).

Again, sorry for the inconvenience,
Mime
