If I'm viewing a pdf in firefox, and I search for a word using ctrl+F, the viewer should jump to the location of the word. But recently for me the viewer is showing the wrong spot in the document. This happens for all pdfs. For example, if a pdf has the word "fox" on page 4, when I use ctrl+F to search for "fox", firefox will jump to page 3 of the document, not page 4. I have to scroll around searching for the word. Any suggestions? Thanks!
