Well, I cannot compile the current version, nor install the deb. Using latest Linux Mint. It took some effort getting all the dependencies right, and it wasn't clear that I had to install the httpseverywhere plugin also provided on your Github account :)

While building, I get the following error that I cannot seem to solve:

CMakeFiles/rainbow-lollipop.dir/src/config_dialog.c.o: In function `rainbow_lollipop_config_dialog_construct': config_dialog.c:(.text+0x265e): undefined reference to `gtk_switch_set_state'
