It didn’t do it by default, but it looks like if you grant Camera permission (Settings:Apps:App Management:Fennec:Permissions), at least “Ask Every Time”, then when I choose an image to upload I use “Media Picker”, then the three dot menu, then Browse, then my file manager app, I can browse the filesystem.
If the Camera permission is set to “Don’t Allow”, then the three dot menu is not present.
I normally just use the Eternity client for lemmy, rather than Firefox Fennec, though.
I’m able to do so in Firefox Fennec 138.0.0.
