Reinstall the latest version. Even if you have the latest version, just reinstall, a file within may have become corrupted. If issue persist... find the folder its in and erase the WHOLE thing. Backup your bookmarks first.
For me, it's the BRAVE BROWSER. The best internet browser. I even download the BRAVE BROWSER on my phone, tablet, laptop, and desktop because the BRAVE BROWSER DEVELOPMENT TEAM is so friendly and more than willing to oblige.
One time I asked for 3 ads to be blocked and they blocked three. I said, "Wow, three for free!" and the nice friendly BRAVE worker laughed and said, "I'm going to call you 3-for-free!".
Now the BRAVE BROWSER greets me with "hey it's 3-for-free!" and ALWAYS blocks every ad, cookie, and tracker. It's such a fun and cool atmosphere with my BRAVE BROWSER, I use it at least 7 times a week for my daily browsing needs which include work, pornography, school, and stalking my whore ex wife on facebook.
I even use my BRAVE BROWSER to browse Read It, it's amazing! What a great BRAVE BROWSER.
