I know that the default browser check is intentionally disabled in the portable version of firefox. Neverthless I would like to enable this check.
The reason: I do use the portable firefox located on a normal HD of my PC. The advantage is, that I can run it in several different OS- Installations. So I do have usually 3 or more installations of Windows on my PC that reside on different partitions. With Portable Firefox I won't have to configure the whole bookmarks etc. after a fresh install but can use immedately the familiar Firefox.
But I'm tired of setting firefox manually several times as default browser after some testings or Updates when IE has set itself to the standard browser again.
How can I achieve this?
