47 sourcesIt's a shame Firefox on iOS has failed/refused to support third-party content filters [1] since 2019. Just because they can't bring Gecko doesn't mean they shouldn't try to gain mindshare for the Mozilla Firefox brand on one of the biggest platforms, yet they refuse to put in the resources.

In Mozilla removes ad-tracking code from FirefoxHere's the code, for those interested in finding the bug: https://github.com/mozilla-mobile/firefox-ios/tree/main/Brow...
In How to waste bandwidth, battery power, and annoy sysadminsWhy the “complex” qualifier? The code responsible for the incorrect favicon URL bug is very simple, and part of the Firefox codebase not WebKit:
https://github.com/mozilla-mobile/firefox-ios/blob/bd589c194...
Firefox on iOS has about 200k lines of Swift. As a rough rule of thumb, everything that isn’t directly related to rendering something within the page or executing JavaScript is Firefox code not WebKit code. So bookmarks, syncing, tabs, etc.
In How to waste bandwidth, battery power, and annoy sysadminsIt's an open source project, with a good discussion of the technical issues on GitHub[1]. Probably linked to certain user behaviors, like having hundreds of tabs open, but surely also contingent on the complexity of wedging a browser in iOS. Like maneuvering an excavator into a sandbox.

In How to waste bandwidth, battery power, and annoy sysadminsYeah, Orion's support for Firefox extensions is a big red flag. These 2 issues on the Firefox-iOS tracker[0,1] around extensions and content blockers have long mentioned Orion, but there's no response from Mozilla.

In Platform TiltFirefox on iOS randomly changes the order of new bookmarks, adding new ones to either the top or the bottom of the list. I assume they're assuming ordering in some underlying platform data structure that doesn't support it?
EDIT: I guess it was this, though I think it's been broken again more recently? https://github.com/mozilla-mobile/firefox-ios/pull/11895
At any rate I've found Firefox on iOS/iPadOS to be surprisingly buggy.. tabs hang and need to be closed, not all bookmarks are synced and/or the ordering changing per above, showing sponsored ads in the new tab shortcuts list and needing a force-close until they go away after being disabled, etc. etc.
In Firefox Sync actually worksFixing weird bugs like not loading cookies for a ~minute whenever the app needs to launch (as opposed to restore from background) would be a win too [1]
I switched to Safari on iPhone because I was always logged out of stuff on first load, super annoying. I miss the syncing, but not that much.

In Firefox on the brink?Meanwhile, on the iOS version, they can't even support the OS-provided content blocker API, meaning Safari has better support for privacy-related add-ons than Firefox.
https://github.com/mozilla-mobile/firefox-ios/issues/7374
In Firefox desktop extensions coming soon for the upcoming Android releaseWell, some bugs actively hurt their ecosystem, like the bug in Firefox for iOS that sends corrupt or missing cookies after the application has been tombstoned and is launched again[0]. This will cause you to get logged out of many sites, which in turn makes you use a different browser and at that point you might as well use Chromium on your desktop as well.

In SVG Chromium bug is more than 10 years old> in iOS, firefox really don't have any choice as they can't even use their own engine due to Apple egregious appstore policy.
Funny you said that, out of the top of my head:
- Brave have a full featured adblock built in on iOS;
- Edge(!) have adblock plus extension built in as well;
- iCab have adblock capabilities built
As you can see, there's plenty of options even with Apple engine restriction. They just don't care enough to give iOS users a good experience, see the frustration on these threads[1][2]. It's all fair, I just gave up using Firefox on iOS and stopped caring about Firefox as well. Surfing the web without a proper adblock is just a rollercoast of frustration.

In Firefox Beta for Android now supports custom add-on collectionsI'm fine with calling Blink based browsers "Chrome skins" and WebKit based browsers "Safari skins" but only if we all understand that "skin" isn't just a cosmetic thing. Firefox on iOS has its own features, settings, history, bookmarks, sync system, and other stuff that can create real, noticeable differences. Even if you assume "skin" means just the UI behavior, wouldn't it make sense that there could be a Firefox-specific bug with the URL bar?
To answer the GP's question, this does sound like a known Awesomebar issue that might be improved with a future update to the Places database: https://github.com/mozilla-mobile/firefox-ios/issues/11775
In Improving Firefox Responsiveness on macOSI'm not sure if it's a policy issue here, there's an existing browser[0] that seems to support them.
