Firefox Android peg̃uarã Tekoha Aty

I keep getting Japanese language on searches. This started while I was in Australia in October. If I'm on WiFi it searches English but on cellular it searches Japanese the tries to translate to English.

I removed and reinstalled, all my settings are set to English. This is the only app doing this. I'm currently not using any VPN either

I like mozilla browsers like Firefox, Firefox Focus and Other version like Fennec(F-Droid) ( I think it's not maintained by Mozilla, anyways leave it)

My default browser in settings is Firefox Focus and even after keeping it as default I got a prompt to choose between different browsers and I have choosen Firefox Focus again for Always but I don't understand why Firefox(Release/Stable version) kept overriding the default settings by itself without my permission, I don't understand how it can make itself as default browser engine? I want Firefox Focus to be default but Firefox kept on annoying me by making itself default, so I just deleted Firefox(Release) and Downloaded Fennec(F-Droid version), it's not causing this problem.

I hope, I have explained my problem as clearly as possible and I had downloaded that Firefox browser from Play Store and not anywhere else also it's the latest version. So it's not tampered and if you guys want details about my mobile

Device: Huawei's Honor 9 Lite LLD-AL10 Model, Android version 9 and EMUI version 9.1.0.

I haven't tested this bug or issue from other devices yet because currently I don't have anything else.

So Mozilla Support team members. Kindly solve this issue please, Thank you....

Firefox browser for Android is my favorite, but it still has many shortcomings, like you cannot use private DNS in it, there is no option of bookmark import export, you cannot move bookmarks up and down and create a group of tabs and you cannot use themes, and there is no Hindi language in the inbuilt translate, and the speed of the browser is also low and not smooth, I request you to work on whatever I have told you and implement it in the browser, thanks

How do I turn off swipe to delete a link in collections? If I'm scrolling through the links and my finger a millimeter or two to the left the link slides and is gone with no recover option. Ive lost so many important links this way.

As the pic shows, firefox android has a terrible performance on android to show the code with Chinese characters using its default mono font. (It seems that the default mono font doesn't contains Chinese and therefore it fallback with what system intended defaultly)

So, what should i do to change the font settings? I've.explorered for the anawer and none of them could work...

So I've tried everything I've looked through all of the different forms talking about language and changing it on your phone to English and then changing it on settings to English that's not working I've deleted the data and the app and read downloaded it and it's still stuck in Japanese nothing I do it's changing it back to English. In the dumbest thing is there is no translate for Japanese on Firefox yet on the mobile app it says it's not supported. So how on Earth am I supposed to change it back to English if I already have the device and the app both set to English?

Firefox doesnt even enter passwords for Firefox. HOW DO I DESIGNATE FIREFOX AS DEFAULT SEARCH ENGINE AND PREVENT IT BEING CHANGED. the directions how to add a search engine are indecipherable and dont work.

when I click a link, always a pop up comes up asking to which app the link should use to open.. Let's say I have another app as default but when I browse in Firefox it's always asking for which application it should open.. when I click firefox it's always opening a new tab to open the link. it's keep opening a new tab everytime
