Hi add an image

Repeat this is firefox with Kantu installed with addons from mozilla, after installation give these errors (kantu still has not been used)

I tested on Win 10 and Win 7 in Firefox 66 and could not see this issue.

Is anyone else having this issue?

Any special Firefox settings?

I have not any special settings on firefox, with firefox 66 i see other problems of compatibility, frequent freezes, macro do not start after launched via command line, test case after some macro stucked (but macro works well individually), run command with shared variable see more errors, now i use firefox ESR 60 (quantum too) and kantu works better I’m having fewer problems.

With firefox 66 I could not work with kantu because of too many problems showed me and they seem random.

Can you please retest this with V5.0? Thanks!
