Hello, as of recently Firefox got the new tool to highlight text in the native PDF viewer, and I really enjoyed using it. As of today, I had not updated or changed versions, but I suddenly lost access to the highlight tool option. Refreshing the page didn't work, downloading a new PDF and opening it didn't work, restarting Firefox didn't work, and I haven't seen anybody else have this issue.


Firefox Version> Firefox Developer Edition 125.0 Beta 8 (20240403091602) OS> Windows 11

I don't know if this is just an issue due to it being in beta, or it being on beta 7 but not 8, but either way any solution is appreciated!

The PDF highlight tool is currently limited to early beta which ended with 125.0b7, you can enable it by changing pdfjs.enableHighlightEditor to true in about:config.
