Hi

Thank you for your question and thank you for beta testing the next release of Firefox.

I am using a version a couple ahead of the one you are testing and I am not seeing this issue, but that does not mean that what are are seeing is not important. I recommend that you file a bug at Bugzilla and we can make sure that this is fixed prior to that version of Firefox being finally released.

Thanks for your help.

This bug was caused by this setting, normaly set to 1 : user_pref("dom.ipc.processCount", 16);

VIEW_SOURCE in WORKING EDITOR I use Firefox offline to manage personal files in html, pdf, txt, etc. They never go on-line. I used to use "view source" on these pages to activate a working text editor which allowed me to edit HTML or text without going to the source folder. Your "view source" function no longer allows active editing of the displayed file. Can you please continue the capability to have "view source" open a working editor. Choosing an editor with "about:config doesn't seem to work any more.

view_source.editor.external boolean False by default - (True) and view_source.editor.path string the user needs to add the path to the editor

are still present in about:config .

Have you tried setting them both at the same time?
