You just need to rebuild resp. reinstall libpdfium-nojs. It is a package with a dynamic version number, which means that it pulls the latest source code and determines the version number out of source code. Which is a higher version number than what you see in AUR.
Example:
AUR has aur/libpdfium-nojs 5060.r1.558516c323-1
But the version I have istalled is libpdfium-nojs 5249.r4.c5f61025a7-1
And that happened simply by reinstalling libpdfium-nojs
I downloaded the package build with "paru -G megasync " and edited the PKGBUILD file to pull version 4.7.2.0
But version 4.6.8.0-2 is also working just fine
Would you consider flatpak? Don’t know if that would work for your intent. I also had a AUR package I couldn’t build yesterday, installing the flatpak took me 1 min.
I just realized that too. I didnt use this extension for a while. But it does not show up for me either.
Looks like the nautilus integration is not working anymore with gnome 43:
Fair enough. Perhaps it maybe and option if you can’t build it via AUR package. I have very few packages outside the Arch repo, flatpaks are containerized and should technically be safe to use. But digging into the weeds may indicate otherwise, as would using any proprietary software. Here I mean in the context of where and what a given flatpak installs things on my system.
Edit: but if it requires a gnome extension, might have to wait the fix for 43
