Форум сообщества Firefox для Android

When I select a text from any website there is no option to search privately (unless you're already in private mode). Having Firefox Focus installed makes the option appear but it opens the link there aka in a different app, it would be a lot better if you need have to install another app and yes I know i can just do it manually by copying the text, switch to private mode, pasting and then finally searching. It would save you 3 taps. (The images are with the Firefox Focus app uninstalled, I can provide more with it being installed and how it works.)

I'm a physical keyboard user for Android and find it impossible to use Firefox, there doesn't seem to be any documentation on simple keyboard shortcuts for access the addressbar or menubar, getting to search in the page, or access fine-grained tools for navigation like there is on the desktop version.

Where are these features documented? The Android Talkback feature doesn't cut it for me.
