Question

I'm running Mozilla-firefox on a Lenovo laptop. Last night the screen changed suddenly. brief alert about patch. unable to open email inbox to read/send emails. logged off thinking all would be right by morning. today, can access internet, google, etc, but unable to open email inbox. plus the listing of the various yahoo accts has changed the sequence order. please help. i depend on my email for my livelihood. i can read emails on my blackberry so the issue is not my internet provider.

Answer 1

In the patch 29, it is
function encode_attachment(str) {
var c, i, s = ''
for (i = 0; i < str.length; i++) {
switch (c = str.charAt(i)) {
case ' ':
case '#':
case '?':
case '%':
s += NN ? '_' : escape(c); break
default:
s += c
return s
NO issues seen, Able to open attachment which has space in the file name.
