NOTES

Note 1. The DuckDuckGo browser claims to be private. However, in May 2022, security researchers discovered the DuckDuckGo browser was secretly NOT blocking Microsoft trackers on third-party websites. See for example reviewgeek. Due to that grotesque duplicity by DuckDuckGo, I have lost all interest in the DuckDuckGo browser. I do not expect to test it regularly. FAIL.

NOTES

Note 1. I am only testing the major versions. That is because the version numbers are so long that an ordinary person would not bother to compare minor version numbers.

Note 2. Microsoft recently removed the “reset sync” button that deletes your data from Microsoft Servers. Now there is no way to remove your Edge browsing data from Microsoft’s cloud. This is a privacy nightmare. For that reason I will not use the Edge browser. I do not expect to test it with any regularity. FAILED.

Note 3. Starting in version 120, the Edge browser now includes an AI function called Copilot. It slurps up your every inquiry and action into itself, with no option to opt-out. This is a privacy nightmare. FAILED.

Note 4. On 2024-02-07, Microsoft released version 121.2277.107 of the Edge browser. In this version, the Copilot AI cannot be deactivated. This is a formidable invasion of telemetry harvesting and a profound violation of privacy. For that reason, I expect to no longer use, or even test, the Edge browser. The only possibility is to turn off the displaying of the Copilot button. However, that does not deactivate the Copilot AI. It is still running behind the scenes, harvesting telemetry and violating privacy. FAIL.

NOTES

Note 1. Since early 2022, the Firefox browser automatically opens the keyboard whenever I open a tab. This bug is annoying and wastes time. This bug was reported to Mozilla back in March 2022. FAIL.

Note 2. The Firefox browser claims to be private. However, in 2024, security researchers discovered the parent company Mozilla had secretly installed ad-tracking code in the mobile versions of the Firefox browser. Apparently they removed it after they were caught. This is a terrible violation of trust. References: Techzine Global and AdGuard. FAIL.

NOTES

Note 1. All scores rounded to the nearest whole number.

Note 2. My understanding is that JavaScript performance is rather hardware-dependent. For that reason, I expect a newer device will have a better score.

Note 3. In every case, the operating system and all apps were updated to current.

Note 4. All testing was done at BrowserBench » Jetstream.

Note 5. In 2023 and 2024 I tested the iCab Mobile browser. However, on December 14, 2021, using the new Privacy Report in iOS, I learned the iCab Mobile app was secretly sending my private data to more than 20 data brokers. iCab Mobile was doing that without my consent and without forthrightly disclosing it. I removed the iCab Mobile app from all my devices.

Note 6. These are my own test results. Your results may vary.

Note 7. Ashley Belanger, writing at Tech Crunch, lists additional privacy-focused browsers for iOS:

Aloha browser from Cyprus
Vivaldi browser from Norway
Opera browser from Norway
Ecosia browser from Germany

Note 8. In April 2019, BrowserBench updated their JavaScript test to version 2. The scores from JetStream 2 are not comparable to the scores from version 1.

Note 9. The Onion Browser is the most secure browser available for iOS. For that excellent reason, the Onion Browser does not do well in performance tests. So concerning performance, I don’t test the Onion Browser. I respect it.
