Captcha issue on page creation

I cant save page I just created. I press "Im not a robot" checkbox and successfully pass the verification, but green tick resets to empty checkbox again and it is impossible to save changes.


I`m using Firefox 84.0 64-bit (only AdBlock plugin installed) on Linux Mint 20 64-bit.

Update 1: I do not have this issue, using code editor instead.

I imagine that the AdBlock plugin breaks the CAPTCHA, especially if the AdBlock plugin also has a tracking protection. The current CAPTCHA tries to track you to judge if you are a legitimate user. There are multiple tickets regarding the use of CAPTCHA in the wiki: Your case sounds similar to #449.

I will try to disable AdBlock on osm wiki.
