You can also do that with reynard [0], and eventually firefox itself [1], if you just move to the EU or Japan.
Or switch to android, an operating system that didn't need government intervention to let you install a browser engine.
While Apple has technically permitted third party browser engines in the EU, they have made it so onerous and expensive that no company is likely to build one. Apple remains the gatekeeper and will likely deny any builds for many years while they abuse the EU courts in delay tactics.
The EU has been fumbling the application of the Digital Markets Act. They have been sitting on a judgement of non-compliance regarding third party stores for literally years now. By now they could have moved to forced compliance and huge fines. It's not clear if there is some kind of hidden diplomacy happening, a desire to not anger Trump, or sheer incompetence. Either way, I have lost hope that the EU bureaucratic engine will ever do anything to help ordinary people. Their only function now appears to hurt the very weakest in society, because they can't fight back.

Do we have a timeline for when proper firefox will be available on iOS?
I’m in Japan and my App Store is set to Japan, but if I try to install ublock origin
“Add-ons are not compatible with Firefox for iOS. Try installing them on Firefox for desktop.“
Just so you know, "move to Europe" is pretty complicated inside Apple ecosystem. You can't move your App Store account from one country to another while you have any subscriptions active. You cancel them, wait for them to expire, and only then you can switch. So, for example, if you subscribed to an app yearly in January, and then cancelled your subscription in May, you still have to wait until January of next year. Very annoying in practice.
