Hi, if you want Firefox to ignore the Initial View option in the PDF for Bookmarks Panel + Page and show only Page, you could try the following. It will also ignore other sidebars that may be set to open in the document. (1) In a new tab, type or paste '''about:config''' in the address bar and press Enter/Return. Click the button accepting the risk. ''More info on about:config:'' [[Configuration Editor for Firefox]]. ''The moderators would like us to remind you that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future.'' (2) In the search box in the page, type or paste '''onload''' and pause while the list is filtered - Firefox should display about five preferences starting with "pdfjs" (3) Double-click the '''sidebarViewOnLoad''' preference to display an editing field, and change the value to '''0''' then press Enter or click the blue check mark button to save the change. The different values for this preference mean the following: * -1 = UNKNOWN [tries to honor the setting in the file] * 0 = NONE * 1 = THUMBS * 2 = OUTLINE * 3 = ATTACHMENTS * 4 = LAYERS What do you think?
