1. When we press Home button in the app toolbar, It opens a new tab and sends the active tab in background instead of closing the tab. The correct working of Home button is to show Homepage in current tab. For opening new tab, we can use "New Tab" option. Because of this all tabs keep getting stored in background and it's quote irritating. 2. Same for back swipe gesture, the tab gets stored in background instead of closing. For example, I clicked on an Article in Google Feed, it redirects to Firefox, now after reading the article, I swiped back to go back to Google Feed. Now swiping back gesture doesn't close the active tab, instead it stored the tab in background. Because of this too much tabs gets stored in background and need manual effort to remove the tabs. So, Fix these two features.
