I use MyYahoo as a start page and Firefox as my default browser. Have done this for years. Today, my bookmarks at this page started loading differently in the afternoon with errors in the names and taking up a lot more screen real estate. Also, the punctuation for names of bookmarks is now defiled. The page doesn't allow me to edit them either. I thought it was a Yahoo problem, but apparently not, since everything loads normally using Chrome.

Solutions?
