This uses the currently supported WebKit GTK, which is more up to date but also fatter.
|
||
|
|
|
||
|
|
WebKit is a huge mess and leaks all over the place. I'm not even sure about anything that's going on. Resources are taken up but only loosely released. You can start with as low as a 50MB memory load, but you will never go back to that. There's no apparent way to run JavaScript garbage collection, and I doubt it would help. -- Par of the course for JavaScript supporting browsers.
|
||
|
|
|
||
|
|
Good: This is a little less fat than Chrome, probably.. maybe.. at least at first
|
||
|
|
Bad: It still sucks
|
||

|
Prerequisites (Debian and cousins):
|
||
|
|
sudo apt install python3-gi python3-gi-cairo gir1.2-gtk-3.0 gir1.2-webkit2-4.0
|
||
|
|
|
||
|
|
Below "# Script start" you can find a setting for software mode, which you should use if you're experiencing trouble with the viewport not showing up or freezing.
