Hello, (I am for the first time here (as I am by no means a software developer, but a Web & graphic designer), so please, be forgiving!:-) I am a Firefox user since v. 0.8 or 0.9, don't remember well (right after I switched from Mozilla 1.7.x). I enjoy this browser ever since! The problem with the warning dialog on close is a serious one (for me). Of course, I can revert back to FF 2.0.x, but I prefer FF 3.0, because it has a lot of nice new features and improvements! Yes, I do understand the point that 'If the session with opened tabs & windows will be restored automatically next time FF is started, then no need to warn to user he/she closes all of the tabs' sounds kinda logical; but consider this scenario: 1) You close FF by accident - clicked on 'close' button by accident, or some kbd shortcut which closes the app window; anyway, FF is closed. If I had 50 tabs opened, I'll have to wait some time, before FF opens again. Also, if I was filling some form over https, its content will be lost, etc. So some trouble (and data loss) can be a result of my accidental FF closing! In Firefox 2, no problems with that - select 'Warn when closing multiple tabs', and you're done! Every time you close Firefox, it asks 'yes/no'! (And no accidental closings! And this wasn't dependent on if the user have set up the session to be restored next time.) 2) At the same time, I want Firefox to remember and re-open automatically all of my opened tabs, next time I start it! I do not want to manually select 'Yes, restore my tabs'/'No, do not restore them next time' every time I have to quit Firefox! I want this setting permanent, automatic, as I always need my tabs restored! 3) So, finally, as I wish at the same time to be able to close all of the opened tabs (windows) *after* confirmation (warning); and to have my Session automatically restored all of the times, as well, it looks like this cannot be achieved by no means in FF 3.0, which is a major problem for me (and looks like, not only for me). What options do I have? Wait for Firefox developers to change the behaviour back to '2.0', so FF will ask 'Are you sure you want to close all of your tabs?' on close, no matter Session Save is set to active or no? Or I could try to dive into the code and fix things at least for me... Well, I wouldn't write here if I knew how I could fix ('hack') the code:-) I see 3 proposed patches attached to this bug, but I do not know how I could copy-paste the code from them to the relevant file in my Firefox installations, so I can get again 'Warn on closing multiple tabs' feature working, *no matter* if I have set next time Firefox starts to show my homepage, blank page or all of my windows and tabs I have closed last time... So, if someone can help me in this, I will very much appreciate it!! :) Just a hint or two, how I could make things work for me, please? :-) Or, better yet, please consider reverting back to FF 2.0 behaviour in this matter. Some users will be happy not to be asked each time they close Firefox 'Are you sure?...'; but this dialog can be dismissed ["don't show again"], right? And for others, it is important not to be able to close FF by accident AND have at the same time have set up in preferences "Automatically restore opened tabs/windows next time I start FF". Maybe someone could write an extension, I don't know... Thanks for all the help and for listening to my arguments! :-)
