icons buttons don't work in Netsurf browser when I click reply or new thread
 

The icons that appear when you click reply to post or start a new thread, like the quotes, attachment, url hypherlink etc that appear in message typing section when you click reply to thread don't seems to activate or work when click within Netsurf browser. Netsurf 3.10

All I can say is try using the tab to highlight the tab and hit enter key on keyboard.

It's in french . Best I can do for now.

Tab didn't get a response

NetSurf doesn't support Java Script so the editor buttons can't automatically insert markdown into the text field.

edit>prefrences>content
has a check box called Enable Javascript.

After enabling it, some of the icons in reply to thread apear to be inserting themselves (working) which is what I was seeking .I am not able to see an inserted cursor when I type to a reply, it's invisible.
