Nearly Perfect Performance

Aside from 1 or 2 Quirks, Firefox Focus Runs Smoothly. i Do Note a Bug with Sharing YouTube Links.
Unless you go Directly To the Video you wish to share, Much Of the Time, it will Simply Share the YouTube home page instead.

While i experienced 1 or 2 similar instances on other sites, it was Mainly YouTube where that Was most Noticeable.

[August 2026 Update]
I REALLY, REALLY Wish They Would Put The “Trash Button” Back Where It WAS.
They Swapped The Location Of The “Reload Page” Button & “Trash Button”

Or AT LEAST Give Us The Option To Customize The In-App Interface.

Avoid at any cost.

Firefox Focus and its Safari extension are disappointing for users who already use a reputable privacy and security solution with system-wide ad, tracker, and malware blocking. (Read, for example, a good VPN).

Focus mainly adds another overlapping layer of content blocking while still lacking the feature I actually want: a proper HTTPS-Only mode that automatically upgrades HTTP connections to HTTPS or blocks insecure HTTP. Its protection is limited to supported browser content and cannot guarantee that all ads and trackers are removed.

For users without any other protection, Focus may offer some useful tracker blocking. But for people who already have comprehensive device-wide security and privacy filtering, it feels largely redundant and not worth the extra app, configuration, and potential website breakage.

Mozilla should provide meaningful HTTPS enforcement and functionality that complements existing security tools instead of duplicating them. Until then, I cannot recommend Firefox Focus or its Safari extension, and I’ll be warning others about these limitations.
