Also, I learned about the changed 'r' and 'shift + r' keyboard shortcuts, but I am also hoping to get help with the menu buttons for the not so computer savvy coworkers who also look at a lot of pdfs throughout the day. I looked at the Adobe Acrobat preferences in the program on my computer and also tried to find a place for preferences through the Adobe Acrobat extension through Mozilla. I searched all over to see if there was an option to show more buttons but was unsuccessful. This sounds like it is not that big of a deal but when you have to view pdfs through the mozilla extension all day for your work tasks, the extra time it takes adds up. Now, you have to click on the double arrow all the way on the right and then move your mouse down the menu to rotate the pages.

Select Open with and choose the PDF viewer you'd prefer. When you're in the Downloads folder, right-click on the file. Choose Open Containing Folder from the drop-down menu. Before the rotate buttons were at the top. Right-click on the folder icon of the PDF file you'd want to open. To use it just click the Reader icon on Firefox add-on bar.

Select and Read Reader lets you select any portion of the web page and read it by choosing Read in Reader option in the context menu. I have it set up so that the menu bar is at the top by default by unchecking the 'display in read mode by default' option in the preferences menu of the Adobe Acrobat program on my computer. Reader provides Auto Scroll functionality so that you can read your web pages in a steady pace. It seems there was an update over the weekend that affected the location of the Rotate Clockwise and Rotate Counterclockwise buttons on Adobe Acrobat menu bar within the Mozilla extension.
