Hello: I use firefox browser only occasionally, because Pale Moon fits my requirements much better. Unfortunately Pale Moon is becoming unusable for a number of web sites, including youtube. Therefore I installed the newest ESR version of firefox, 78.10.x esr. Apart from that I don't like it very much it loads youtube and some other sites smoother than Pale Moon. But there are some "features" I cannot accomodate to, and would like to change if possible. 1. How could I restore the old selection behavior in the url bar, that is: one click inserts the cursor into the url, two clicks selects all. I don't want to use three clicks. I found a hack here: https://blog.tusooa.xyz/2020/10/01/Fix-firefox-address-bar-clickSelectsAll-b... I applied it to my omni.ja, and it changes selection behavior except the selected by double click text is not put in the primary selection list, and can not be pasted with the middle mouse click. I would appreciate if someone could help me to restore that behavior too. 2. I really miss a button that clears the url bar, so that I could use a middle click to paste text into the address bar without selecting and deleting before pasting. 3. Is it possible to restore multiple tab rows while they remain rearrangeable? I found some css hacks to restore multi row tab bar, but then the tabs cannot be rearranged. 4. How could I get rid of the annoying update notification popup? I do know these are not opensuse specific questions, but this list has experienced users who might help solve these issues. Thank you in advance, Istvan
