Web based feed readers are kind of a pain to use. They often implement changes that you don't want, while taking away features that you like.  Local readers are much better when it comes to this, because you can revert to an older version in case of adverse changes.

Smart RSS Reader is a feed reader extension for Firefox and Chrome that I have been using for a week; I am quite impressed by it so far.

Install the add-on and click its toolbar icon to open a new tab with the extension's RSS reader. It has three panes, each of which has a toolbar at the top. The left pane is the feeds pane and lists all RSS feeds that you're subscribed too. Selecting a feed displays the title of the articles published by the site in the center pane. It also displays the author's name and the date when the article went live.

The New Orleans Saints have cut three-time Pro Bowl right guard Larry Warford, whose three-year run as a starter was cast into doubt by the club's selection of interior lineman Cesar Ruiz in the first round of the NFL draft. Warford, whose termination was announced Friday by general manager Mickey Loomis, started all 44 games in which he played for New Orleans since signing a four-year, $34 million contract in 2017. The 6-foot-3, 317-pound Warford also was named to the Pro Bowl for a third straight season in 2019, when he started 15 games.
