is there anyway I can use helvetica family again?
In other applications, yes. You can apply a user style in Firefox that substitutes Helvetica with another font. My style uses [https://fedorahosted.org/liberation-fonts/ Liberation Sans] but you can replace that with Arial or some other font.
# Install Stylish and restart Firefox when prompted.
#* https://addons.mozilla.org/firefox/addon/stylish/
# Click the ≡ Menu Button and choose Add-ons.
# In the Add-ons Manager, click User Styles on the left.
# Click the Write New Style button at the top. Paste the following in the text box, give the style a name, then click the Save button.
<pre><nowiki>
@-moz-document url-prefix("http://"), url-prefix("https://") {
@font-face {
font-family: Helvetica;
src: local("Liberation Sans");
@font-face {
font-family: "Helvetica Neue";
src: local("Liberation Sans");
</nowiki></pre>
If you don't want to install an add-on, you can use the ''userContent.css'' file instead, but I don't recommend it.

Is that bug in firefox? or is there something wrong with that font famliy?
On a Mac, Helvetica is included with the operating system and there shouldn't be any issues. Firefox has trouble rendering this font on Windows, perhaps because people tend to install one of the many illegal copies floating around the web.
If you want to troubleshoot the issue,
# Start Firefox in a new profile.
#* [[Use the Profile Manager to create and remove Firefox profiles]]
# If you have the same problem with the font, post a comment on the following bug report.
