#17 Plugin Load Error in Windows Firefox 2.0

[Joerg Mehring]

After installing the tclplugin31-win32-ix86.xpi in Mozilla Firefox 2.0.0.6 and loading a web page with an embedded tclet I get an error:

[NpInitInterp] Failed to initialize Tcl!

After confirming the dialog box I get a subsequent error:

[PANIC] could not find token "npInstance" in RegisterToken

After confirming this dialog box the browser terminates with a runtime error.

Running the plugin in Internet Explorer 7 works fine. Also running the Linux plugin in Firefox 2.0.0.5 works great!

Any suggestion? Does the plugin work with the windows version of Mozilla Firefox? Has anyone tested this?

Thank you in advance.

The log from the plugin shows that the bug relies on an error comparing the variable tcl_version with a constant. But why does is appear only in Firefox and not in Internet Explorer?
Here is the log:

I've received multiple reports on this now, and I believe the issue is one of locale. If you use a numeric comma (where 1 == 1,0), then that is getting improperly propagated to us by FF, but not by IE.

I support your hypothesis, Jeff: just tested it on WinXP Pro (SP2) Russian and FireFox 2.0.0.12 -- it has "," as the decimal separator in the system locale settings and firefox crashes as reported. If I change it to ".", all works OK.
