Rated 4 out of 5 stars

It makes me sad that I can't write a five star review. I have been using this program for years, and I have never had an issue. The export/import has been changed (ironically at the same time I upgraded to Windows 8), and I have lost all my connections I have been gathering for years. I noted the removal of the %, and I did that, and it didn't fix it. You can't change export/import routines after years of creating a standard! At least write in a backwards compatibility module. Well, what am I to do now? I'm depending on a standard that is in flux for my development. FTP is crucial, and if the standard for backing up and restoring sites is in flux, you can't count on the program anymore.

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).

The same applies for the files you're trying to import. If you have further issues, email me mimecuvalo@gmail.com and I'll help further.

Again, sorry for the inconvenience,
Mime

This is the primary reason I am faithful to FireFox. I have been using it for a few years, and this is by far the best addon FireFox has to offer (there are several good ones out there, but this one takes the cake). The only thing I have ever found wrong with it is it asks me for a username and password twice sometimes when I'm connecting (specifically to a FileZilla server), just hit cancel and all is well. Outstanding plugin!

This review is for a previous version of the add-on (1.99.2.1-signed).
