i don’t like gnome/gtk/libadwaita ui components, they are extremely unpleasant to use, but i especially do not like the gnome/gtk file selector, it is almost unusable, so normally, when using firefox or a firefox-based browser, i change these settings in about:config shown in the screenshot to force the browser to use the xdg desktop portal file selector, which is usually either the lxqt one or the kde one depending on which desktop i’m using
however, i recently updated to librewolf 152, and despite my about:config not changing, librewolf is now using the gnome file selector both when downloading a file and when selecting files to upload somewhere
how should i fix this? i have tried changing these values from 1 to 2 and to 0, nothing changed. other programs use desktop portals just fine, so i’m not sure what is causing this
i dont see any relevant messages in stderr of the terminal i opened librewolf from, not sure if there is a log file i should be checking instead or something
@kemona_halftau im on kde, and since an update on librewolf a few months ago, it uses kde's file picker instead of gnome's, and i didnt change anything in about:config
maybe reinstalling or deleting all its user profile data would help?
also, if you are using the flatpak, that might also be the cause, probably. I use the debian package and it's fine here

@Sorro i’m using librewolf-bin form the aur
@kemona_halftau well, looking at their website, librewolf-bin on the aur seems like an officially supported thing, so i doubt that's the issue (unless the code differs from the debian package somehow, which i doubt because why would it)
so yeah, deleting librewolf's data is the only option i can think of. Though, maybe the flatpak is fine? idk this seems like a weird bug 
@kemona_halftau
Set “widget.use-xdg-desktop-portal.file-picker” to “1”.
Ensure you have “xdg-desktop-portal” and “xdg-desktop-portal-kde” installed.
