QuickTime X opens up previous session's videos at startup.

I've emptied "Recently Opened" but there are two videos that automatically start up with Quicktime.
Help?

I can't believe so many people are experiencing this and Apple haven't come up with a solution yet. When I find out how top delete Quicktime without affecting itunes I will.
You can't delete QT without corrupting your operating system since it is a structure embedded in the OS and is utilized by virtually all applications in one way or another. You can, however, delete the QT X Player app without adversely affecting your Mac if you so choose. Most serious QT users install the QT 7 Player app and make it their default player since, when keyed for "Pro" use is more feature rich and, thanks to third-party codec components, is more compatible with legacy file containers/compression formats.
This is very poor and very microsoft... I'm so disappointed in Apple, the support people want me to pay to get a solution to this.. I've got my amazing iMac on my desktop and my video's won't play properly in the standard player. Absolute rubbish. It's all going down hill for Apple... they've taken away frontrow as well!! Stupid decision! pointless having a remote now.
Somewhat confused by the point you are trying to make here. If referring to the original topic title of this discussion, then tell the support people to turn off the "Restore windows when quitting and re-opening apps" System Preference option. If referring to an inability to play legacy files—especially those for which active support was dropped by the originator more than a decade ago, remember that QT X is supposed to be "new generation" software that will likely be under developement for at least the next decade and which specifically targets more modern, highly scalable compression formats used by today's mobile and HD devices. I personally use VLC, MPEG Streamclip, HandBrake, QT 7 Pro, and QT X.1 depending on the requirements of the particular workflow for the given project in which I am currently engaged.

Firefox will not open my previous session

Firefox 4 will not open any previous session once I shut down. I can have say 5 tabs open, close firefox, and reopen it and the session was saved. If I have those same 5 tabs open and shut down, then turn on my computer the next day, I can click on firefox, it will highlight the icon, and the highlight will disappear after about 5 seconds, and then I have to click it again, and it will open a totally new session. How do I fix this?

Make sure that you do not use [[Clear Recent History]] to clear the "Browsing History" if Firefox is closed.

HELP! Can I retrieve my previous session? I only just ticked the "open with previous session" preference but it seems too late! Can I still get the old pages/tabs I had open?

That could be a problem, unfortunately.
But most likely the pages you were on are stored in the History list. Try pressing Cmd+Shift+H to get the History window.
To help prevent this from happening to you again in the future, I can recommend the extension [https://addons.mozilla.org/en-US/firefox/addon/2324/ Session Manager]. It is quite powerful but may not be able to help you any more than the History at this point.
Please let us know how above works out, and if we can be of further assistance. Detailed feedback is appreciated and helps us to help more users with similar problems.

Even though I have FF set to "Show my windows and tabs from last time" every time I open FF it just opens the home page. Why won't it open my previous session like it use to, even if I have that selected as the default state?

Nothing more to provide. Simple problem not opening previous session tabs when browser is opened after being closed. Was working fine until the upgrade to 7.0.1.

Make sure that you do not use "Clear Recent History" to clear the "Browsing History" when Firefox is closed because that prevails and prevents Firefox from opening tabs from the previous session.

Is there any way to do a manual session restore if Firefox doesn't open your previous session - and doesn't give you that option?

I've got Firefox configured correctly and it always opens my last session. However, sometimes when the computer crashes and a second Firefox window is open (this time it was either a pop-up window or the Firefox update window), Firefox only recognizes that window as the "last session," and it loses the most recent multi-tab session. (Hmm, maybe what I need is "re-open recent sessionS" or "last multi-tab session" ?!)
Anyway ... is there any way I can retrieve yesterday's open tabs without picking through my history and finding them one-by-one?

The presence of a sessionstore file with a number (sessionstore-1.js) indicates that at one time there has been a problem with accessing sessionstore.js and that Firefox wasn't able to rename sessionstore-1.js to sessionstore.js
You can see by the file date of sessionstore-1.js when that has happened and if it an old file then you can remove it or you can try to copy that file to sessionstore.js to see which session it brings back.
Make a backup copy of all sessionstore.* files elsewhere to be sure that you do not lose a session before doing that.

Firefox will not open with previous session. Option automatically resets to default.

I set options to: "Show my windows and tabs from last time". But, when I start Firefox, it does not save this option and reverts to the default option. I've tired disabling add-ons and refreshing Firefox, but the problem still occurs.

After reading several posts in the Support Forum I tried a solution. I deleted the "sessionstore-backups" folder.
Please try this: click the menu button ≡ and then click help ? > troubleshooting information > profile folder - "show folder". Then a new window will open up. In this window look out for a folder named "sessionstore-backups", delete this folder and restart firefox afterwards.
The problem was resolved.

Firefox opens the old browsing window (previous session) every time i try and open a new window, how do I change this back?

Every time I go to open a new window, the old one will come up instead. For a while it was working fine, then I kept needing the old window and would use the 'restore previous session' feature to access this. However, even after I didn't need it anymore (and without me selecting the feature, it would still open the previous session.

It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
Delete the files sessionstore.js [2] and sessionstore.bak in the Firefox Profile Folder.
* Help > Troubleshooting Information > Profile Directory: Open Containing Folder
* http://kb.mozillazine.org/Profile_folder_-_Firefox
If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.<br />
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).

What happened to the Bookmark all Tabs/Save and Exit/Open previous session feature in 4.0? If this has been taken out then 4.0 is of no use to me. I'll have to go back to 3.6

In 3.6 when ever I closed the browser with multi tabs open it would give me the option to Save and Exit. Then when I reopened the browser it would give me the option to open the previous session. I could also bookmark all open tabs. All of these features appear to no longer be present in 4.0. If this is the case I will be forced to uninstall and reinstall 3.6.

Bookmark All Tabs - you can get it when you right-click on a tab, or use keyboard shortcut Control+Shift+D.
Firefox now always stores the old session, and you can access it by going to the History menu and selecting "Restore Previous Session"
If you want Firefox to display the message to save the session, it can be turned back on by changing some preferences.
# Type '''about:config''' into the location bar and press enter
# Accept the warning message that appears, you will be taken to a list of preferences
# Locate the preference '''browser.tabs.warnOnClose''', if its value is set to '''false''', double-click on it to change its value to '''true'''
# Repeat this for these 3 preferences '''browser.warnOnQuit''', '''browser.warnOnRestart''' and '''browser.showQuitWarning'''
If you always open the last set of tabs, an alternative approach is this:
# Click the orange Firefox button, then select options to open the options window
# Go to the General panel
# Change the setting "When Firefox starts" to "Show my windows and tabs from last time"

Launching Quicktime always opens multiple files

After upgrading to Lion, Quicktime always re-opens all of the movies I've opened in previous sessions. For instance, if Quicktime has already opened 15 movies, it will re-open those 15 plus the new one. The only way I've found to open a single file when launching QT is to manually close each file I've opened and clear the 'Open Recent' list before quitting the porevious QT session. If the 'Open Recent' list is empty upon launch, it doesn't open the previous movies. It is happening with every file type, including WMV via flip4mac. And it's happening on all three of my Macs !!! I did uninstall flip4mac and SliverLight but QT still behaves this way. Seems to be a problem with QT itself. QT isnlt having problems playing the files, though. It's working fine in that regard, including playing WMV files via flip4mac (which I reinstalled). VLC and other media players still open files at they should. I'm quite surprised to not see any discussion on this anywhere so maybe it's a problem unique to my Macs. Anyone have any ideas? What am I missing here? Thanks, folks.

Is there some way to prevent this stupid prctise?
There may or may not be. If there is, I have yet to find it. (I'm still in the "familiarization" stage.) If there isn't, it would make a good enhancement request, especially if it could be turned off/on by application.
I often open several files, then quit the app rather than closing each individual file. This is counter-productive.
I tend to close players after use, so this doesn't really bother me. (On the other hand, I make a lot "what if" saves and am not really fornd of the idea of a new "auto-save" feature confusing me between my project saves and its saves.)
Oh, well... To each his (or her) own.

Is it possible to show previous sessions tabs AND homepages on startup?

Hi :)
I'm wondering if it's possible to open all the previous session's tabs at startup and also open the homepage(s) at the same time? I've tried fiddling with everything in the general tab but with no success. I couldn't find any solutions on the net either so here I am.
Incase there are other ways to do what I want; the reason I want it is so I can force myself to at least look at the news everyday without losing my previous session's tabs. Silly I know but seems like a simple feature that I might be missing somehow - it would also be useful to always open email etc. that folk tend to open as soon as the browser starts anyway.
If it does exist - how please? xD And if not I might pop it in the suggestions box.
Thanks very much,
Mossy

That isn't possible AFAIK.<br />
Only if all open tabs are pinned then you get one new normal tab with the startup page.
A possibility is to open the home page in a new tab with a middle-click in the toolbar Home button.

Previous Session

Despite setting to keep previous tabs open, on each close and re-open of Firefox, all tabs are closed and only the homepage tab is open in new session.
Happening on multiple Mac computers. If Force Closed, option to restore previous session is available. But not had success in closing Firefox normally and re-opening with previous session tabs.
Is there a bug?

Make sure that you do not close all open windows, but close the Firefox application (Firefox > Qui) while the window(s) are still open.
In case you use "Clear history when Firefox closes" :
*do not clear the Browsing History
*Firefox > Preferences > Privacy > Firefox will: "Use custom settings for history": [X] "Clear history when Firefox closes" > Settings
Make sure that you do not run Firefox in permanent Private Browsing mode (Never remember history).
*https://support.mozilla.org/kb/Private+Browsing
*Firefox > Preferences > Privacy > Firefox will: "Use custom settings for history"
*Deselect: [ ] "Always use Private Browsing mode"

My browser won't remember my tabs, even using restore previous session;how do I fix this?

Opening the browser, it goes straight to my home page even though it's set to open the previous session, the restore previous session in the history menu is greyed out. I cannot even look in recent tabs or windows because those are empty too.

My settings have been set to reopen tabs from previous session. y privacy is set to remember history, and the browser remembers site history just fine. The browser simply loses my tabs.

Every time I launch Firefox 4 it opens 3 or 4 blank windows, no longer opens the tabs from the previous session and does not show my bookmarks sidebar.

I have to manually close the extra windows and restore the tabs from the previous session, and reopen the sidebar. In disgust I uninstalled Firefox 4 and reinstalled 3.6. Everything works fine in 3.6. Looks to me like Firefox 4 has many major bugs and is not yet ready for prime time. I'll stay with 3.6 for now.
