With regard to Wayfarer's (v7.7 & v7.8) issue (seemingly) with reCAPTCHA, if you have to use the reCAPTCHA protocol/utility/challenge more than twice, then Wayfarer seems to indicate that it's "had enough of that" and just offers the initial stage of reCAPTCHA - the "revolving blue arc" and you get nowhere further to completing the challenge. So, you have to reboot if you want to try again, which seems annoying and weird!

Also, if I use v7.5 of Wayfarer then I can resend/complete the reCAPTCHA challenge numerous times without the issue/behaviour that v7.7 and v7.8 seem to exhibit - preventing the challenge from being completed. So, it does seem to be isolated to these last 2 versions of Wayfarer with regard to reCAPTCHA, from my use of the various versions of Wayfarer I have tested so far.
