This brought up several options and I changed these options to this configuration:
View_source.editor.args user set string -u
View_source.editor.external user set boolean true
View_source.editor.path user set string /opt/kde3/bin/kate
After doing that Firefox and Kate worked exactly like you want.
I tried those settings. No luck. I also tried --use in View_source.editor.args. No luck. I'm using FF 3.6.24.
I personally don't want to have the web page appear in a kate instance that I am already working in, so after testing I removed the -u
I understand. And thanks. I just want FF and kate to work the way I want. :)
After a lot of hammering, screaming and kicking I got it to work the way I wanted. Now that sessions work "my way" I use sessions heavily and like them a lot. So please don't make them go away...
Yes, a lot of hammering, screaming and kicking, which is absurd. No software should be that cantankerous or difficult to configure. I am using the --use parameter in all shortcuts and *.desktop files, and like you, eventually tamed kate to my liking. Yet I can't get FF to use the same window that is already open.
