Thunderbird for RSS?

Am I the only one using Thunderbird strictly as an RSS client? I've seen countless RSS clients recommended here over the years but none ever have the features to make me switch, mainly due to lacking extension support (for things like uBlock Origin and Bypass Paywalls) or privacy concerns from not running on a local Linux desktop. (I haven't heavily used the e-mail functionality in Thunderbird in over two decades. I haven't tried the Chat or any other functionality at all.)

Is there something I'm missing out on? Is there a client with all the same features and then some that I just haven't found yet? I've looked at Feedly, Inoreader, and many others through the years but none have risen to the level of replacement. It's not broken so I'm not looking to fix it but I'm open to hearing how others manage their feeds to see if there's any possible improvements I've overlooked.

Full disclosure: I've donated in the past to Thunderbird/Mozilla, including company matches.
