Hi all,

I explain how important the plugin is to us.

The plugin is based on  detection of internet security.

There are tons of users use our product, including the plugin(great FF).

We hope the problem can be fixed in time before version 45 releases, or we cannot commit user to provide a secure surfing environment on the internet.

Our plugin is to observe any url changed/opened and then analyze if the url is risk/dangerous. Give a warning to users etc.

The manner to observe url changed/opened is implemented in main process using xul overlay launching NPAPI plugin.

So is there an alternative way interaction with NPAPI plugin receiving url changed/opend ?

Thanks a million in advance.

Hi all,

Sorry for disturbing you again.

I have a few questions.

1.       On what version does the e10s will be turned on by default?
2.       When does  the native messaging of web extension will be ready?
3.       Is any suggestion on NPAPI plugin not working? How to get through  the transition of wen extension ready(especially on native messaging).

Bug 1237402 adds some code to make this work. I just checked it in today so it will be available on Firefox Nightly (version 47) in a few days. To use it, you need to set the pref "plugin.load_in_parent_process.<your-plugin-MIME-type>" to true. Then it can be loaded in the main process (and not in the content process). I hope this works for you.

hi bill,

I try it out, but this nightly build in 47.a01 still doesn't work for me.

The following is my step:
1. input cabout:config
2. create a new pref named 'plugin.load_in_parent_process.application/x-nptswp'
3. set the pref to true
4. restart FF, the plugin not loaded in plugin-container.exe

Did I miss something?

As I said, it won't be available in Nightly for a few days. Try again on February 1st.
