Following video of thelinuxexperiment and all the news against mozilla.
I finally switched to librewolf completely.
I exported and imported all kind of data too.

But I want to use ffsync only to keep my mobile (android) in sync with my pc (want to sync history also so flocuss etc will not work)
So I want to enable ffsync in librewolf

I have seen faq but as mozilla recently introduced their terms of usage (and all the hate against it)
Is it still private enough to use ffsync? what can be downsides?

I want to use an electron based app named trilium notes on my system.
I got wayland/niri on nixos
I installed trilium by writing it in configuration.nix and rebuilt system but after starting trillium it gives following error

[7292:0311/205146.782132:ERROR:ozone_platform_x11.cc(240)] Missing X server or $DISPLAY
[7292:0311/205146.782227:ERROR:env.cc(255)] The platform failed to initialize. Exiting.
The futex facility returned an unexpected error code.
Aborted (core dumped)

I tried setting ELECTRON_OZONE_PLATFORM_HINT=auto and DISPLAY=:0 in all three combinations.
This is all I got from internet.
And nothing worked.

So basically I need help from community
Thanks

Is there any solution to configure termux to use system default theme instead of what i setup using termux styling app? Even a basic option to set different themes for different modes will help l, so that i can configure it to switch to zenburn when system is in Dark mode and Google light when in light mode.
