I’m a user of Sync for Reddit Pro. I hope we can have more price options to remove the ads starting from a lower amount. Let’s say, $5, $10, $20, $30 and maybe a custom amount (>$5). In this case those who are willing to pay $20 can remain to do so or even more but others can now support the developer by the amount they feel fit.
Container in Firefox is better IMO. Use this addon to enable the feature https://addons.mozilla.org/en-US/firefox/addon/multi-account-containers/
