@Chi-oma
Your concerns regarding malware is we well founded however I would like to mention that the general rule applied to most extention/store sites for new additions is that they inspect and QA the package before including. I know in the past generally only developers utilized extensions so this was unnecessarily but times have changed.
I would encourage the addition of this feature for Android, as mentioned Edge and Firefox have already made available.
Just my 2c.
Thanx
PS apologies for resurrecting an old post.
