The Aloha browser is one of the smaller players in the browser field. There's not a lot of news surrounding it.
It's probably safe. There hasn't been a major report of the browser doing anything nefarious, like with how the Brave browser had the DNS leak when on the Onion network.
That said, I would not trust it 100% when it comes to privacy just because they're very small and not a lot is known about them. They say on their privacy policy that they do not collect any personal information but I would still be very wary.
Regarding #2, https://adblockplus.org/subscriptions ABP supports a configurable list of filter subscriptions. My questio is exactly which ones does Aloha use and are there plans to allow us to configure this?
Can you provide more detail? I use both Aloha and Nord VPN. Do you use the Wire Guard Protocol on Nord?
Also Aloha servers have been some of the best I’ve found other than Mullvad and Nord and sometime better than both. Speed and utility wise.
