It uses the Android webview to render websites

So, Chrome-based.

It uses Android Web view which is essentially just Chrome without the interface, and is entirely proprietary. It suffers from all the drawbacks of Chrome based browsers with the added problem of being an Android component so out of much, if any, control of the developers.

This app should not be a serious consideration for anyone who is privacy or security focused. The very first thing a secure browser should be providing is it's own rendering engine. Even providing it's own chrome based rendering engine would be more secure than this.

Also in terms of extensions, as it is Chrome based it's extensions such as uBlock will have the same privacy breaking restrictions as the rest of the chrome ecosystem with manifest v3 which favours Google's advertising business over user security and privacy.

"Not chrome" ... uses blink engine...

Uses AdBlock not Ublock Origin...

Ty but I am fine with IronFox

I tend to turn off JavaScript for most sites and I found enabling and disabling it on this browser to be a pain. Has that changed?

Also, it is webview, so you cannot harden it unless you root and download a hardened webview.

Can you use ublock? built in. Im going to give it a go.

I've seen this when bopping around in the F-Droid catalogue. Never took it seriously because it didn't seem to communicate well what it was doing.

In general; I usually dislike using Chrome anyways....so much so that I hard disable Chrome on my device, oftentimes via ADB, and download a wide range of alternatives; Kiwi (Plugin enabled), Hermit ([Closed source] Forced Isolation of all domains/sites along a side of ad-blocking and web-app caching baked into the app wrapping it's renderer; which is, of course System Webview. Unfortunately this one is not open source, so I do not often recommend it here and while I trust it; your decisions may be different.) and Firefox (Plugins installed, seems to be replacing Kiwi because it's likely a dead/gone/depreciated/archived project.) I even use URLCheck from F-Droid itself as my "Default Browser" so that I have the power to review each URL and open it in a browser I feel is most appropriate to the context of my browsing and choose the browser I feel can best protect my privacy for a given site. One-off visits often go to Hermit; which promptly isolates away and forgets I ever visited the site while blocking ads with a lighter touch than most plugins I've seen that exist. If a site often breaks in Hermit; usually due to ad-blocking hostile scripts; I kick it over to Firefox where I have extensive plug-in tooling to defang the beast...including tools like JShelter, Canvas Blocker, LocalCDN, Chameleon, Decentraleyes and uBlock Origin.

What I do know is that Android System Webview is far more configurable than you might realize; and that it is absolutely possible to build a browser on top of it. Most importantly; Android System Webview IS NOT Chrome! Yes, it is extremely similar and it behaves mostly the same; but it is based on the Chromium project; which is basically what Chrome is before Google applies all of its own Branding, Customization, Policies and Application touches on it. Does Chromium project mirror what Chrome needs? Absolutely yes, but it does not follow Chrome exactly. In general; Android System Webview is a Web rendering component that other applications can call on and wrap their own code around. This means you are basically free to implement whatever other features you want around the webview; including adding plugins and other things like ad-blocking. My favorite closed-source lite-app browser Hermit does this; and I'm not seeing any significant privacy concerns with that one.
