to fix autofill:
either swith to the KDE5-Version of the Plugin OR
use the KDE5 Version of the method searchLogins inside KDEWalletStorage and compile the plugin yourself.

URL to KF5-Version of the method:
https://addons.mozilla.org/de/firefox/files/browse/521991/file/components/KDE5WalletStorage.js#L224

to fix sync:
- disable KDE wallet and restart FF
- setup sync and use copy the credentials from the internal password manger
- open kwalletmanager and paste the content to the key [email protected],,Firefox Accounts credentials,chrome://FirefoxAccounts and the field password
- enable KDE wallet and restart FF

the credentials should look like:
{"version":1,"accountData":{"kA":"somedata","kB":"somedata"}}

i really like this plugin, but the sync problem is really annoying. However, i can confirm that the workaround below is working for me. (copying the password field from build in password manager)

I also get an error message on the terminal at firefox start that might be related to this problem:

Crashes are still threre for me with 2.2 and 2.3 (homepage of developer).
However, i was able to get rid of them by compiling the plugin myself form svn. The crucial step seems to be, that you build libkdewallet.so so please first build this liib with the provided cmake file and pack the plugin afterwards.

I do not need to disable any jit-compiler in FF or any other special settings.

&gt; I do compile each of the libraries before packing, If you only do that and it works for you it's just luck. We have an open bug on moz-dev about this, the problem is still pointing to a bug in the new JIT compiler, or at least, some incompatibility with it and foreign libraries."

In reply to your comment:
- with "you" i didn't mean the developer, i was guessing that you are building the library before packing. It was ment as a tip for peaple wich want to fix the bug for themselves.
- a littel background information:
-&gt; i am using gentoo and compiled firefox from the sources on my own. Maybe there is a incompatibility beween my compiler / optimization settings and your ones? i use the gcc-4.7.3 with CXXFLAGS=CFLAGS="-march=native -O2 -pipe -ggdb" and kde 4.13.3
-&gt; the recompilation solved teh bug for 5 diffrernt machines (all with gentoo). So the fix seem reliable ti me.

This review is for a previous version of the add-on (2.2.1-signed.1-signed).
