Web browsers are one area where the wisdom of the crowd does not apply. In the old days, the crowd used Internet Explorer, now it's Google's Chrome browser. Don't use either one. The bottom half of this page has many articles that make the case against the Chrome browser. I would also avoid the Edge browser for two reasons. First, it is popular and thus a high value target. Second, I don't trust Microsoft.
Brave has ad blocking and tracker blocking built in, it is based on Chrome, supports all Chrome extensions. It also runs on Android and iOS.
The Mullvad browser is based on Firefox and the Tor browser (which is also based on Firefox). It was first released in April 2023 and I have been using it since the initial release. It seems to be locked down, security-wise, even more than Brave. For example, it gets an excellent rating at the Cover York Tracks tester from the EFF. It is locked down so tight that some websites do not work, or some functions on a website may not work. Still, it is my first choice. Mullvad is a very trustworthy software provider and, despite being a VPN company, the browser does not require the use of any VPN. On Windows, the software is portable and it self-updates automatically. It also runs on macOS and Linux. It has been actively maintained in the 6 months that I have been using it.
I would also consider the Vivaldi and DuckDuckGo browsers on the OSs where they are available.
USING A BROWSER
Web browser extensions are a double-edged sword. If you let them, they can read and modify the contents of every displayed page. This is necessary, for example, with an ad blocking extension. However, it can be abused too. The security around browser extensions is miserable, so I suggest a default posture of installing as few as possible. A very reasonable stance is to only install uBlock Origin and nothing else.
May 2023: I have been very impressed with the DuckDuckGo Privacy browser. As a browser it does a great job of telling what trackers it has blocked on each web page. In addition, it can do tracker blocking system-wide. Like many such apps, it does this by installing a fake VPN. The downside is that the blocking feature can not be enabled while there is an active VPN connection. The tracker blocking feature is currently in BETA but it seemed to work very well when I tried it. It even tells you the type of data that each app was trying to collect.

Section Last updated: September 2022 with Firefox 104 on Windows.
The first thing I do with a newly installed copy of Firefox is to make the Menu Bar visible. One way is to right click on the tab/toolbar and turn on the check for Menu Bar in the window that pops up. Or, you can press the Alt key, then View, then Toolbars and finally, turn on the Menu Bar.
Review the Enhanced Tracking Protection (about:preferences#privacy) settings which offers defense against trackers and more. As of version 104, the choices are Standard, Strict and Custom. See the documentation on this.
Mozilla also has a Facebook Container extension that blocks Facebook from tracking you around the web.
In the Forms and Autofill section (Settings -> Privacy & Security), I suggest disabling the auto-filling of addresses and credit cards.
In the Address Bar - Firefox Suggest section (Settings -> Privacy & Security), I would turn off "Suggestions from web", "Suggestions from sponsors" and "Improve the Firefox Suggest experience".
In the Firefox Data Collection and Use section (Settings -> Privacy & Security), I would turn off all four options: "Allow Firefox to send technical and interaction data to Mozilla", "Allow Firefox to make personalized extension recommendations", "Allow Firefox to install and run studies" and "Allow Firefox to send backlogged crash reports on your behalf".
In the Files and Applications section (Settings -> General) I suggest turning on "Always ask you where to save files"
Secure encrypted DNS is configured at Settings -> General -> Network Settings -> Settings button -> Enable DNS over HTTPS. The options are Cloudflare, NextDNS and Custom. My first choice would be NextDNS for its ad/tracker blocking, but Cloudflare is fine too. By default, Cloudflare does not block ads/trackers. If you have a NextDNS account, then use the Custom option. To use one of the Cloudflare blocking options also requires choosing Custom here.
The Disable HTML5 Autoplay extension by Afnan Khan can stop many self-starting videos.
You can customize the look of the toolbar by right clicking anywhere on it and then selecting "Customize toolbar".
Take a look at about:telemetry which "shows the information about performance, hardware, usage and customizations collected by Telemetry. This information is submitted to Mozilla to help improve Mozilla Firefox". It can be intimidating, but look to see that "upload is disabled".
Another useful "about:" URL is about:performance which invokes the Firefox Task Manager. Somewhat akin to the Windows Task Manager, this shows CPU and storage usage for each tab. It can also be invoked with: Hamburger menu -> More Tools -> Task Manager. Read about it here: Task Manager - see what tabs or extensions are slowing down Firefox.
Root Certificate Authorities: These are companies that vouch for the identity of websites. The browser lock icon exists because some company, called a Certificate Authority, issued a file (called a certificate) that says the website is legit. The problem with this scheme is that there are bad Certificate Authorities (CAs). This can result your browser displaying (for ex) citi.com with a lock icon and, still, you are not at the real Citibank website. There are different lists of trusted Certificate Authorities. Firefox has its own list, many other browsers rely on the list created by the operating system. When you hear about a bad Certificate Authority, Firefox users can delete the company from the trusted list. This November 2022 article in the Washington Post, Mysterious company with government ties plays key internet role, basically says the TrustCor should not be trusted. When I checked Firefox 106 on Windows, there were three entries in the trusted list for TrustCor. To remove them: Settings -> Privacy and Security -> View Certificates button -> Authorities tab -> Pick an entry -> Delete or Distrust button. See a screen shot. In my experience, the button only does Delete, there was no option to Distrust. While you are at it, consider deleting the Chinese Certificate Authorities.

ARTICLES SUGGESTING NOT TO USE CHROME
Opinion: it is time to switch from Chrome to another browser by Martin Brinkmann for GHacks (Sept 2022). His reasons: Chrome is a powerful data gathering tool, Chrome's dominance gives Google a lot of weight when it comes to establishing new web standards, the move to Manifest V3 makes it more difficult to run content blockers and privacy extensions in Chrome.
8 reasons to quit Chrome and switch to Firefox by Alaina Yee for PCWorld (May 2022)

Why You Should Delete Google Chrome On Your Phone by Zak Doffman in Forbes (Nov 2021).
Jan 7, 2021: Today I stumbled across another reason not to use the Chrome browser. I was using Chrome version 87 on Windows 10. In Settings -> Autofill a particular website (x.com for the sake of example) was set to never save the password. It had been configured this way for a while. I opened an Incognito window and went to the x.com website. When I went to login and clicked in the UserID box, what showed up? My userid for x.com. There is no way to tell Chrome not to save the userid. And what is the use of incognito mode anyway, if it has access to the userid of what I consider a sensitive website?
A Long List of Ways Brave Goes Beyond Other Browsers to Protect Your Privacy. Written by Brave. No date.
We're suing Google for harvesting our personal info even though we opted out of Chrome sync - netizens by Thomas Claburn of The Register (July 2020). The lawsuit claims that although Google promises that Chrome users can opt out of surveillance by not providing personal information and by not synching their data, people get spied on anyway.
Google sued for at least $5 billion over claimed Incognito mode grab of potentially embarrassing browsing data by Ethan Baron (June 2020). A new incognito page does not warn that Google knows what you do. It does warn that websites you visit and your ISP know what you do, even with private browsing mode.
Incognito mode detection still works in Chrome despite promise to fix by Catalin Cimpanu for ZDNet (June 2020). Google said last year that it would fix a bug that allowed sites to detect incognito mode, but no fix ever came.
Both Firefox and Brave have defenses against browser fingerprinting that Chrome does not have.
Still another reason not to use Chrome: Google: You know we said that Chrome tracker contained no personally identifiable info? Forget we ever said that by Thomas Claburn of The Register (March 2020)
From ProtonMail: Most secure browser for your privacy in 2020 (Dec 2019). In brief: Chrome is bad. Firefox, Brave, Tor and DuckDuckGo (mobile only) are good.

uBlock Origin works best on Firefox where it can undo CNAME Cloaking. See If you run uBlock Origin, use the Firefox version as it offers better protection by Martin Brinkmann (Feb 2020).
Study finds Brave to be the most private browser by Martin Brinkmann (Feb 2020). Only default browser configurations were tested.
Germany's cyber-security agency recommends Firefox as most secure browser by Catalin Cimpanu (Oct 2019). Firefox was tested against Chrome, Internet Explorer and Edge. Not tested were Safari, Brave, Opera, or Vivaldi. The big finding, to me, was that Chrome, IE and Edge have no option to block telemetry.
It's Time to Switch to a Privacy Browser by David Nield in Wired (June 2019). Good article that covers the DuckDuckGo browser (iOS, Android and an extension), the Ghostery browser, Brave, Tor and much more.
Google Chrome has become surveillance software. It’s time to switch. by Geoffrey Fowler in the Washington Post (June 2019) has a great quote: "having the world's biggest advertising company make the most popular Web browser was about as smart as letting kids run a candy shop." Alternate link
There is a whole website (NoToChrome.org) devoted to the bad stuff about the Chrome browser.

How I'm locking down my cyber-life by Larry Sanger Jan. 2019
Why I'm done with Chrome by Matthew Green (Sept 2018). Paraphrasing: I've loved Chrome in the past, but, due to Chrome's new user-unfriendly forced login policy, I won't be using it going forward.
Bye, Chrome: Why I'm switching to Firefox and you should too by Katharine Schwab (May 2018). Quoting: "I can't even remember why I decided to use Chrome in the first place. The browser has become such a default for American internet users that I never even questioned it."
Then too, there is the issue of certificate revocation. It is a poorly designed system and does not work very well. But all browsers support it - except Chrome. Chrome does its own thing in this regard and their system only works with a very small number of websites. In contrast, Cloudflare is working to improve this with OCSP Stapling.
