There's quite a bit of macOS that's open source. The author links to source code in Firefox, and that source code has links to Apple's source code:

To quote some relevant comments on other threads here:
> If you could grab a profile of the problem with the Firefox profiler and file a bug it would be greatly appreciated. From the sounds of it it's probably an edge-case we're not aware of where Firefox performs very poorly. The problem with this kind of things in Mozilla is that we're often blind until someone brings up the issue and notifies us.

You're confusing general purpose locks with special-purpose ones used in the memory allocator. Firefox has its own GP locks, you can find them here: https://searchfox.org/mozilla-central/search?q=&path=xpcom%2...*
However those are not suitable for use in the memory allocator, and neither are WebKit's. WebKit uses os_unfair_lock within its memory allocator:
https://github.com/WebKit/WebKit/blob/520379e30f3b2b6d4de995...
And so does Chromium:
https://source.chromium.org/chromium/chromium/src/+/main:bas...
Last commit was earlier this year for a Monterey release: https://github.com/apple-oss-distributions/xnu. The next one will almost certainly be for the first build of Ventura. Here is the header for the (private) function os_unfair_lock_lock_with_options: https://github.com/apple-oss-distributions/libplatform/blob/.... Synchronization primitives happen to be one of the things Apple is pretty good about releasing the source to.
I finally got time to try https://github.com/onemen/TabMixPlus and it worked! Thank you for the suggestion.
When was the last time you needed to read assembly code to debug a kernel-level issue in FOSS software? There's a lot of software you can use to profile the entire kernel and userspace[0], or explore the stack trace[1] of your software. If you're not using those and instead debugging your software by counting SIMD calls in the Ghidra editor, you're wasting an unconscionable amount of time.

Do you mean uBlock Origin is no longer being maintained?
https://github.com/gorhill/uBlock/releases shows many recent releases?
I'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 seem to be a known issue that might be improved with a future update to the Places database: https://github.com/mozilla-mobile/firefox-ios/issues/11775
Are there reasons that the "Simple Tab Groups" extension isn't suitable for you? It seems to be well-maintained, cleverly uses Firefox's "hide tabs" API to keep a single window behind-the-scenes, and has integration with lots of other features like Firefox's containers. I think it's an indirect descendent of the old Tab Groups extension when it was spun out of Firefox.

Google is dominating, pushing through Android and via Googles-Webservices and Microsoft is using it now. A reason to worry because developing new web-engine requires an big effort. For instance Microsoft only allows usage of Microsoft Teams Web with a webbrowser based upon Blink. So were back in 2002?
WebKit features also WebKit2Gtk (Epiphany) and Qt5-webkit (Otter) with native integration. They use the native toolkits, which is an advantage! Interaction with the open-source community around WebKit seems rather good and the engine is integrated by others. Gecko seem not to be integrated by others, but by forks only? You remember when Chrome was considered slick and fast? Originally Google used the native toolkit on every platform but know they use an own solution on every platform, like Firefox.
Maybe there is a new kid on the block:
