(*)Detect whether the tab was restored: when onActivated, read the tab setting. If it is not undefined (i.e. true or false), then re-apply, rather than applying the current default.(**)Apply default setting, and store it in the tab setting, if tab.url==='about:blank' - a newly opened tab.
For maintainer: If you change the above, also update scripts/background.js -> function apply().
Some websites disable this add-on. addons.mozilla.org is one of them - hence, don't test hide/show buttons on (the content of) addons.mozilla.org.
Beware some LibreOffice versions are sick. 1:5.3.1-0ubuntu2 on Ubuntu 17.04 exported to SVG well, but 1:5.4.1-0ubuntu1 on Unbuntu 17.10 didn't. 5.4.3.2 for Windows x64 exported well.
LibreOffice Draw > select all elements > menu File > Export > checkbox 'Selection' > as .svg.
