How to set Javascript settings in Abrowser?

I don't know the answer to your question. But after I had some trouble with Abrowser recently (discussed in other threads) I started using Icecat 60.3.0 and it's going well. This version of Icecat has that configuration screen you're looking for. So I thought I would recommend it in case your problem isn't easily resolved. Good luck.

Yes I'm using it. Works allright. Most of the addons don't work however, because of the patch IceCat is. Also some site stop working just using one of the security/privacy settings that's on the front page.

The page you see when you open a new tab is called about:home (you can
also get to it by entering "about:home" into the URL bar. The current
about:home in Abrowser is Firefox's default. Abrowser used to have
checkboxes for various privacy settings at the top off about:home.

The site recommendations were always there, you just had to scroll down
to see them because the checkboxes were at the top.

The reason that the checkboxes are gone in Abrowser is that Mozilla
broke them by removing the API that it relied on. This happened after
the release of Icecat 60, so Icecat is unaffected, but Icecat 68 will
have the same issue.

However, it sounds like quidam is hoping to reimplement the api in
order to retain the checkboxes in Icecat 68, at which point the same
code can be used to bring the checkboxes back in Abrowser. From last
week's Freedom Friday meeting:

The "Preferences Menu" (about:preferences) exposes only a subset of
Abrowser's settings. You can see the complete list of settings by going
to about:config. All of the settings that used to be controlled by
checkboxes are in there. The JavaScript one is called
"javascript.enabled". You might also consider NoScript or LibreJS.

Flidas ISO has Abrowser 59.0.2. After updates, Abrowser's customized tab is gone.
