@adambowles thanks for the prompt response, is #670 also an issue too?

[jonathanKingston]

Oh wait... is this the intended change we made to the + button? It is now a long click instead of a hover?

[adambowles]

...Yep it's a long click

Also FYI my extensions.webextensions.remote is false

[jonathanKingston]

@adambowles thanks! Yeah I think this is only a default on Nightly Windows at the moment. Currently debugging that however I don't think it is fixable without landing my Web Extensions only patch which is huge and untested :(.

Will leave this open for @niteshkumar96 to respond if the issue is the same.

[jonathanKingston]

Closing as no feedback. Please let me know if you see further issues. Thanks for all the help.

[William-H-M]

Hi, I'm currently trying to do it with the long click still it does not appear, not sure if I have to enabled something else.
Currently using FF 54.0.1 (32-bit)
Can you guys guide me through this?
Thanks.
