If you use this kind of functionality very frequently something like Pick Browser may be the way to go. I was looking for a way to come up with my own "default browser intercept" mechanism. I didn't like the Registry mess involved so I took a different approach.
It's not strictly for browsers but a launcher that passes selected text to an application during launch. You can add browsers just by dragging the shortcut to the Popup Window.
Say for example you an in Chromium but you see that page would work better in Firefox. Highlight the address and hit the hotkey. Double click Firefox in the listbox. Firefox opens to the page.
Or if you are using a text editor that does not have link launch feature the way EditPad does. Select the url text in the editor. Hit the hotkey, select the browser from the list.
You can add any shortcut, not just browsers.
Here's a screen shot:
It's also an alternative to SendTo since you can select a file in Explorer and hit the hotkey to pass that filename to any program in the list.
Edit: another cool thing you can do with it(that I often forget to use myself and just remembered) is select 2 folders in Explorer, hit the hotkey, launch FreeCommander or another file manager that accepts folders on the command line, it will open with a folder in each pane.
Edit2: afa using with FreeCommander it's ok if neither folder has a space in the path. It's really designed to pass one command line arg. Has a go with "" to double quote the arg in case of spaces. To pick off folders from Explorer to use with FreeCommander or Q-Dir HalfShell
is better. It passes up to 4 folders to an alternate file manager, wrapping those with spaces with double quotes. Once set up all you need to do is hit Shift-Enter hotkey.
Selector is better for picking stuff out of text or a browser's address bar as noted earlier.
