  "c:\Program Files\Mozilla Firefox\firefox.exe"    file:\\c:\workspace\test.html

Answer 1

If you are only using vi(m) in the console, this will work but you will have to hit enter once to get back to the html document within the editor:

nnoremap <F4> :exe '!"c:\Program Files\Mozilla Firefox\firefox.exe" %'<CR>

If you are using gvim, this will avoid having to hit enter that extra time:

nnoremap <F4> :exe ':silent !"c:\Program Files\Mozilla Firefox\firefox.exe" %'<CR>

Answer 2

Your mapping:

:map <F4> :w !"c:\Program Files\Mozilla Firefox\firefox.exe"<cr> 

translates to (english): "write the content of this file to the stdin of this firefox program" which is most likely not what you wanted to do here.

What you want to do is:

1. Save the current file.
2. Run firefox with the name of the current file as its argument.

The path to firefox and the file name must both be shellescape()ed to deal with the possible spaces in the path names.

This mapping should do what you want:

:map <F4> :w\|exec '!' shellescape("c:/Program Files/Mozilla Firefox/firefox.exe") shellescape(expand(%))<cr>

The question you are looking for:

Open current file in web browser in Vim

This is exactly your issue.
