Infrequently. Sometimes like 5 euros. Could do more but I am not fully reliant on open source. I wish ublock origin accepted donations though.
What I will say is that if you donate small amounts, saving up is better if possible. I know some charities I donate to mentioned transaction charges could be 1 or 2 euros per transaction. So donating a low amount could really eat into your donation.



I am European but it really depends in what service they use for the automation.
