Computer question. Anyone using Firefox (mine's for Mac, if that makes a difference) and have the most recent update where all the tabs are black with gray text? Is there a way to change the color of them? It's driving me crazy because it's more difficult for me to read. (I tried looking in a few locations, like View and Preferences, but am not finding an option to change it.)

ETA: Also, the little thing you could click on in the toolbar to refresh or stop loading seems to have gone away. Why do they have to keep changing stuff???
