On the second site you listed, you can subscribe to the RSS feed from the Bookmarks menu. If you prefer to have a toolbar icon, you can find one in the Customize dialog. You can get there using either:

• View menu > Toolbars > Customize
• right-click (or equivalent) and blank area of the tab bar > Customize

Drag the icon to a convenient location and drop it there.

On the first site, I can't figure out where the feed is. ??

The ohsheglows.com website shows a feed item available for me, but the www.stayathomechef.com site doesn't offer a feed in Firefox and in Google Chrome.

Did you place the RSS feed icon on a toolbar?

Otherwise you need to use the Bookmarks Menu to subscribe to a feed.

Use Toolbar Layout (Customize) to open the Customize window and set which toolbar items to display.

• View > Toolbars > Customize (press F10 to display the menu bar)
• Right-click empty toolbar area

Thanks! I didn't even know about the option from the Bookmarks menu. Instead, I worked around it by using the add content from feedly (the reader I'm using). It was just weird, cause I could see the buttons using Safari for both of these sites, but they just aren't there in firefox for me.
