Thanks, but that didn’t work. Log says “invalid url”.
Firefox documentation has this example:
firefox://open-url?url=https://www.google.com/search%3Fq%3Dfirefox%2520for%2520ios which works.
But when I try this action firefox://open-url?url=https://www.google.com/search%3Fq%3D%[[selection]]
I get
firefox://open-url?url=https://www.google.com/search%3Fq%3DFirefox%20for%20iOS
The example seems to encode space as %2520 instead of just %20. How can I accomplish that?
