import and export don't work if password contain "&"
Export: passwords that contain the character & are ignored
Import: Parsing error if an .xml file contains the character &
I just tested this issue in a new/fresh Pale Moon 27.6 (32bit) profile. (Win 7 x64) Tested it by changing my github password to a password with the & and also ~!@#$%^&*.
Export: passwords that contain the character & are ignored
Then I used to extension to export to an xml file. "&" and "%" were saved as "%26" and "%25" respectively to my xml file. Removed all my passwords, cookies and cache. Then imported successfully the xml file. Then signed-in again to github without having to type the password.
Still BEWARE !! - NOT everything is OK - see the issue when one of fields contains characters outside of ANSI table- https://github.com/fligtar/password-exporter/issues/45#issuecomment-343693396

Pale Moon has its own fork of this add-on - Password Backup Tool, where all these issues have been fixed.
