Salve!  I, too, am very interested in this.  I use two firefox profiles - one for browsing and one for development.  And I use the addon called "ProfileSwitcher" in both profiles.  What that does is that it always pops up firefox's "choose profile" dialog that asks me which profile I want to launch.  It also gives me a toolbar button to allow me to launch another profile - but it doesn't do anything at all about which instance is the "default browser".

Now, whichever profile I launch FIRST on the system - that one will be the default "Firefox".  And if you go to settings and tell ANY Firefox instance to check whether it is the default browser, each and every one will say that it is already default.  The system's "default browser" is only for the browser, not the instance.

This may be a useful link for this thread as it refers to some registry settings.


So I would like to choose which instance of Firefox is the "default browser" via this nice Browser Tray Switch.

I created a thread for this at SuperUser.  We'll see if anyone comes up with an answer!

[I originally posted here, but nobody ever answered... I guess the thread was too old].

Also, it seems that the "default instance" is controlled by Firefox in Application Data\Firefox\profiles.ini.  There is an ini entry there for "default=1".  Problem is that you seem to have to restart all instances of Firefox...

[edit] I know I posted in on a new thread, but the topic is the same.  Is anybody out there?

Skwire,  It happened again, and this time, I did some testing and narrowed it down to the point where I can successively reproduce the failure.

The GUI is fine as long as it is running, but if there are too many characters in clip.txt when ClipTrap starts up, the GUI fails to load completely - the application starts, and it still captures, but GUI doesn't function right.  (I have some screenshots I can email to you if you like).

So, to reproduce the GUI failure, close ClipTrap, create an empty clip.txt file, and paste "some string in this here line" (without the quotes) till you have 14922 lines of that phrase.  ClipTrap will start okay with this.  Now close ClipTrap and add one more line to the clip.txt.  When you restart ClipTrap, the error should happen. 

Now, I don't think it has to do with the number of lines - that is, the number of carriage return/line feeds.  Because, if you take those 14922 lines + 1 and join them so that you only have one line, ClipTrap will start okay - but if you duplicate that really long line so that you have two lines, ClipTrap *won't* start.

So, it is just the GUI that has issues when it starts.  If it is already started, you can have millions of lines in your clip.text and it is okay.

Anyway, there are a few ideas to play around with.
