However, from the answer on this question on SE Android, I learned that
about:config is no longer accessible on the stable version of Firefox for Android.
I have the following constraints in roughly the order of decreasing concern. Please keep these constraints in consideration while answering the question, but I am still welcome to learn about solutions that violate some of these constraints.
- I do not want to use nightly or beta versions. They might have security vulnerabilities or unexpected behavior.
- I do not want to change any Firefox configuration files on the file system, unless from within Firefox. I don't know much about Android application and I am afraid I might break something while messing with files.
- I do not want to install any add-on on Firefox unless it is opensource or is widely known to be trustworthy.
