I understand where you're coming from, but I honestly find Firefox Preview's built-in tracking protection blocks enough ads on its own. I'd encourage you to give it a shot. (Though, to reassure you: proper adblocking is on the roadmap.)

On the other hand, QR code scanning is necessary for a good Firefox Sync setup experience, and that genuinely seems crucial to the MVP: we don't want your data stranded on one device unless that's explicitly what you want.

Any idea why after sync I can see history from my desktop browser, but no bookmarks? There are only 3 clean folders on Firefox Preview.

That's upsetting. Please do report bugs. We do fix them. Bookmark sync had been working in Nightly for weeks, so I'm really surprised. I imagine it's hitting some kind of exception on your bookmarks.

Done https://github.com/mozilla-mobile/fenix/issues/3774 :)

It looks like that should have been resolved a month ago with build 1.0.1921 (https://github.com/mozilla-mobile/fenix/issues/2252)... are you sure your bookmarks are set to sync (check in about:preferences on desktop)? If so, try forcing a new sync Firefox Preview by hitting Settings -> Sync -> Sync Now.

Yes, the only thing I'm not syncing are passwords. Are those 3 folders under "Desktop Bookmarks" visible in clean install before syncing? https://imgur.com/q1W7GgZ Maybe it's synced somehow only partially? All those folders are empty. And also on my desktop browser I can't see bookmarks I created in FP. I tried hitting "Sync Now" multiple times since yesterday, it always looks like it's working, after a second there's "Last synced: 0 minutes ago"

And I don't see FP under devices in https://accounts.firefox.com/settings/clients?service=sync&c....

for passwords you can just use the firefox lockwise app

I removed FP and installed it again, this time with pairing through QR code, it again looks like it's working perfectly, but I can't see bookmarks, only history. And there is no mobile session under devices in https://accounts.firefox.com/

I'm not sure if it's prioritization so much as just Reader mode being easier because it doesn't need that much from the extension API. Adblockers need to do more browser-level things like intercept HTTP requests, while Reader mode can be done with just DOM/CSS manipulation.

Also, reader mode is the only way non-mobile websites are readable on my phone. I left chrome on my phone for it (now I use Firefox Focus as my primary mobile browser for the vastly better privacy, but very much miss that it seems to have no reader mode). If this has reader mode I am absolutely going to use it as my backup for when Focus breaks a site over Chrome.

When it came out I considered reader mode a killer feature, and coincidentally it also tends to remove the ads. Or at least the ones not embedded in an article, which is good enough for me as long as they remain stationary.

When Chrome first came out I stopped using it cause it didnt have adblock. Then when it did it was still crippled and I realized Google is in the Ad business so I never used Chrome since. This is very correct adblocking is a necessity, if they even include a Mozilla Adblocking DNS server for the browser thats fine to me. As long as I dont see ads.

I wont give up on Firefox anytime soon. I would love to see some serious competitors though.

I don't want my browser ignoring my DNS settings!

I would assume it would be opt-in if they went with this.

Everyone switched to ublock once adblock+ starting taking payments to not block certain ads.

Most people who care about adblocking will choose whatever browser suppoerts adblocking over anything else honestly.
