A community-driven, unofficial Reddit browser plugin is called Reddit Enhancement Suite. 

RES was created expressly to function on OLD Reddit. Most features of the new version won’t operate.

Reddit Enhancement Suite is independently created and is not associated with or formally approved by Reddit.

RES is totally free, much like open-source software, beer, and everything else.

The new release of RES

“Hey everyone, sorry, we could have conveyed this better. We didn’t anticipate it would automatically disable the extension for people upon release, and they’d get this big terrifying notice about it. Although it appears quite strange, it is legitimate and okay.” read a statement on the Reddit website. 

Although RES requires communication with Twitter when you are on Reddit (to support Twitter growth inline), it does not really execute while you are on Twitter.

RES is still free, open source, and not sold to a shady data miner, despite the countless offers that still periodically arrive.

The user claimed that the site was disabled

According to the user, ‘the website was inaccessible. I received news that Reddit Enhancement Suite is deactivated, and one user inquired. It seeks entry to an arbitrary convoluted onion site. I find this to be rather fishy. It’s time, in my opinion, to uninstall the application and file a Chrome Store abuse report. What exactly am I misinterpreting?’

‘It’s the address for Reddit’s onion service on Tor,’ according to one of the replies.
