Issues with built-in PDF reader
I've been using the built-in PDF reader in version 5.0.97-beta.57+07df7d0de and am experiencing some minor issues:
1. How does one set the zoom level to "fit to page"? The "Resize automatically" option doesn't always work. It appears to work on my larger 24 inch (2560x1440) monitor. However, on smaller screens (14 in 1920x1024 laptop screen), it is still zoomed in too much for a US letter size page.
2. When "Resize automatically" does work, I can use the left and right arrow keys to navigate the pages one page at a time. However, if I use PgDn and PgUp, it advances slightly less than one page, making the document slowly slide down the screen as the page isn't fit to the screen anymore. Does anyone else experience the same behavior?
3. I have a PDF (presentation) whose pages are landscape US letter. Is there a way to only show a single page at a time? Currently, I always see one page together with part of the following page.
This could be related to question 1 above.

You can change the PDF's zoom level in Zotero through the "View" menu or by using a keyboard shortcut. For example, use Ctrl/Cmd+0 for "Automatic Zoom":
https://github.com/zotero/zotero/issues/1986#issuecomment-877064552 In Firefox, "Page Fit" can be selected through the zoom menu in the PDF viewer, but this option is currently missing in Zotero's View menu. Note that there's no "Page Fit" shortcut nor a "Page Fit" button in Firefox's PDF viewer. The latter is explained here: https://github.com/mozilla/pdf.js/issues/14286. It seems to me that there're only "continuous" (or "scrolling") modes in the default pdf.js viewer. "Page Fit" might result in a single page being shown, but you can scroll it. In Firefox, you can get a proper single-page view if you enter the presentation mode, Ctrl+Alt+P. The presentation mode seems to be disabled in Zotero, though.
