Why not make an autorun binary that registers Mozilla Portable as a default browser?

i also have an issue a few have raised here already, but there’s still no resolution to it… after following the listed steps to make firefox portable the default browser, it now works fine if and only if it’s not running. that is, if one clicks on a link while firefox portable is not running, it starts and loads the clicked link as one would expect, but if firefox portable is already running, then you get the message “firefox is already running but is not responding. to open a new window you must first close” instead of simply opening a new tab for the clicked link. any help would be appreciated.

Thanks! That worked perfectly.

My system became very messed up after having Firefox full install then a /Firefoxportable and then switching to/Firefox folder due to wanting to make the profile correctly integrated into the portable from the full.

It kept wanting to create a new profile in “C:\. . .\Application Data” every time I clicked on a link in another program. Ten seconds with this little download and everything is working perfectly again.

Thanks! Much appreciated!

Works nicely for me (XP SP3). One issue it doesn’t fix is opening PDF links with the default browser, not IE. (I’m still using Adobe Reader 6, no need to change it)

1-) If I running only one instance of firefox portable, how do I to open a webpage in a new tab? (Avoid Firefox is running… message)

2-) Windows Live Messenger still opens pages in IE…

What happens when you unplug the USB which has Portable Firefox? Does it switch back to the earlier browser?

Worked for me just fine with Firefox Portable and XP. I am not using FF from a USB drive though so not sure if that might be the difference?

Not working for me either. Running google desktop and asking it for an index status still tries to open IE.
