Recently Closed Tabs is not working for me

Recently closed tabs is not working for me. Whenever I go to History -> recently closed tabs is not available and the shortcut does not work. It happened a few weeks ago and when it first happened, the shortcut would open tabs from weeks earlier. I can't find any information on this and would like to see it fixed.

There are other things that need your attention regarding modified prefs that show in your system details list.
Reset the general.useragent.compatMode.firefox to false and all network.http prefs on the about:config page.

I have updated latest version 29.0 firefox in windows 7 machine. All the UI looks fine. Undo close tab is not working for me. Is that not been addressed?

Undo Close tab is not working in windows 7 for firefox latest version 29.0

You can do this via CTRL + SHIFT +T as well.
Can you try to start Firefox in Safe Mode to see if Firefox works properly with no error? You can start Firefox in Safe Mode below:
*'''Windows/Mac''': Go to Help > Restart with add-ons disabled
*'''Linux''': Run ''firefox -safe-mode'' in the Terminal/Konsole
If Firefox opens up fine with no problems, it's probably one of your extensions that's causing the issue. You can re-enable your add-ons one by one until you find the one that causes the issue upon being re-enabled.

Alt + Tab macro not working for Sculpt Comfort Mouse in Windows 8.1

Hi,
I cant get a macro working in Keyboard and Mouse Centre for the Alt+Tab action. I've created the macro previously on windows 7 and all fine, but will not work on 8.1
Alt(press) delay(10ms) Tab delay(10ms) Alt(release)
I have a sculpt comfort mouse, though I don't think that is a culprit, as the macro itself does not work.
Alt+tab works fine on the keyboard, no problems at all.
Please help as this is spoiling my interactions with my OS, which I use almost all day most days.
Thanks,
Paul

Hi,
The macro you mean is Macro Recoder, isn't it? As far as I know, this product may be not compatible with Windows 8.1. I found the link below show its system requirements:

In addition, it would be better to contact Macro Recoder support for further assistance:

I don't want my recently closed tabs to be saved... Any way to prevent this?

It has been a long time since I have used Firefox (got a Macbook, and for some reason just used Safari for a long time), so please forgive me if I am just missing something in the Firefox settings.
Anywho, I have Firefox set up to not remember my history because I like the privacy it offers. I think it is odd that I have it set up to delete my history, yet when you go to "History", it keeps a list of all my closed tabs... Doesn't that kind of defeat the purpose of having the browser not save my history?
Is there a way to prevent Firefox from keeping this list of my recently closed tabs?

Note that Firefox keeps a list of one closed window even with browser.sessionstore.max_windows_undo set to 0, so you may have to open another window with one tab and close this window to purge websites from this list.
See also the browser.tabs.closeWindowWithLastTab pref on the about:config page.

Ctrl + Shift + T doesn't work anymore. History -- Recently Closed Tabs still works. Other hotkeys still work.

I am using Nightly-Elm 21.0a1 Recently Ctrl + Shift + T stopped working. History --> Recently Closed Tabs still works. Other hotkeys also still work.
I already tried Safe Mode, didn't work. In a new profile it does work.
This guy (https://support.mozilla.org/en-US/questions/853883) seemed to have the same problem. The solution offered was to transfer some files from a fresh profile. I am not sure what files to transfer. I tried the prefs.js, but that didn't help.

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.

Closed all firefox windows by clicking the x 'cancel', then 'close tabs'. After reboot, couldn't recover open tabs, (options were not highlighted under History , i.e. Recently Closed Tabs or Recently Closed Windows). Why couldn't I recover my tabs?

When rebooting mac, I closed all firefox windows by clicking the cancel "x" and then clicked "close tabs". After rebooting I could not recover my open tabs, as none of the options were highlighted under History , i.e. Recently Closed Tabs or Recently Closed Windows.

I have a licensed copy of Adobe Acrobat X Pro for Windows. I recently switched over to MAC OS and would like to move my Adobe X Pro over but the CD will not work for Mac OS? Can anyone assist me with this conversion? Best, James.

Best,

you cannot use your pc license to install on a mac. you would need a separate license (and serial number) for that.
adobe allows platform swaps, but only with the latest (xi) version, Order product | Platform, language swap
your option to use acrobat on a mac are to upgrade to acrobat pro xi and change platforms, use a windows emulator (parallels/boot camp etc) on your mac or swap with a third party.

The multi-tabs is not working all the time. Windows7 Firefox 4.0.1 I have the correct opetions set for multi-tabs.

The multi-tabs is not working. I have the correct options set for multi-tabs. But when I open Firefox and try to add a site from Bookmarks it uses the same tab that is opened.

Right click a tab and you will get the option to bookmark all tabs. Or use keyboard '''Alt + B''' which opens the old style menu. You can make changes to Firefox, as explained in this post: [/questions/799856#answer-155765]

The new version has made it hard to easily view recently closed tabs. Is there a way to restore that part/function of the browser?

In the older version (do not know which number), there was an easy way to view all the recently closed tabs from a drop-down menu, which could be accessed from the top-left of the browser.
Now, you have to go to History>View History Sidebar. And even then, there is no view for the recently closed tabs.
I liked the simplicity of being able to see the last tab that had been closed, and the one before that, and the one before that — all in chronological order. Now, there is no way to tell which tabs/links were closed when.
I hope this makes sense. ... I even installed a few add-ons to help me with this issue, but they didn't do the job quickly and easily.

That's not bad, but it does not give me control over opening the exact tab I need. I assume this opens all tabs that were closed in any given session? That could be a lot of tabs. I do miss the fine-grained control and convenience of the older version. Sorry, I sound picky, but this issue has really affected my browsing and working experience quite a bit.
Anyway, thank you for your time and help, Philipp.
Hopefully the developers will put it back in at some point.

When Firefox crashes, tabs aren't saved, and Recently Closed Tabs/Windows are grayed-out

Although I had "Show My Windows and Tabs from Last Time" set in Options, my tabs aren't being restored after a crash. I also had my Home Page set to my Yahoo Mail page upon opening a new session. I then changed my Home Page to a blank page, but that hasn't worked to restore my open tabs after a crash. To make matters worse, under History,Recently Closed Tabs and Recently Closed Windows stay gray, so I can't restore the open tabs from there, either.

Make sure that you not run Firefox in [[Private Browsing]] mode.
In Private Browsing mode some menu items are disabled (grayed) and some features like visited links and others are disabled and not working.
You are in Private Browsing mode if you see "Tools > Stop Private Browsing".
See [[Private Browsing]] and http://kb.mozillazine.org/Issues_related_to_Private_Browsing
You enter Private Browsing mode if you select: Tools > Options > Privacy > History: Firefox will: "Never Remember History"
To see all History settings, choose: Tools > Options > Privacy, choose the setting '''Firefox will: Use custom settings for history'''
UnCheck: [[ ] "Automatically start Firefox in a private browsing session"

Wake on Demand: Not working for some services, others OK

I haven't been able to figure this problem out... Wake on Demand for a previous generation Mac mini running Snow Leopard 10.6.8 works for things like a CrashPlan automated backup but does not work for things like remote SSH login or Screen Sharing. In all cases, the services are being originated on a latest generation iMac running Mac OS X Lion (10.7.2).
While it's not an earth-shattering event to get off my backside and walk over to the Mac mini across the house to press its Shift key to waken the thing, it gets rather old to have to keep doing so, especially since CrashPlan automated backups are taking place while the Mac mini is otherwise asleep (the sleep indicator is slowly pulsing).
I've been through the Apple tech notes regarding Wake on Demand for Snow Leopard 10.6 and have ensured that AirPort and its network are at the top-most position in their respective lists. Other than that, I'm not sure what else I can do. Wake on Network is enabled in the Snow Leopard Mac mini's network System Preferences and there doesn't seem to be any on/off option in the AirPort Extreme base station (just recently updated to 7.6 firmware).
Any thoughts... hints... suggestions?
One final note: this Mac mini is new as of July 2011; just days before the latest generation of Mac mini came out. It came pre-installed with Snow Leopard and, as soon as the users of this mini find software replacements for the old PPC style applicaitons they're used to using, will be upgraded to Lion. However, I feel a bit unsettled in making the move to Lion if I can't get a Snow Leopard feature to work properly. There's no telling if the Lion upgrade will actually fix this behavior or make it worse.
Thanks in advance.

I don't think you can wake on network with a closed lid. Try keeping the lid open and putting the machine to sleep. Does it work?

When I close a tab, and I go through my history of "Recently Closed Tabs" or press Ctrl+Shift+T, my recently closed tab doesn't open and it doesn't get saved in the "Recently Closed Tabs" options under history. What do you think happened?

Does anyone else have this problem? It's in my history, but not under "Recently Closed Tabs".

Make sure that session restore is enabled and working properly.

Undoing 'Recently Closed Tabs' no longer available - please help!

I find myself unable to access the 'undo closed tab' option, which I have previously found so useful. When I go to History > Recently Closed Tabs, the Recent Closed Tabs entries are greyed-out. How can I reactivate this essential functionality please?

-> Tap '''ALT''' key or press '''F10''' to show the Menu Bar
-> go to Help Menu -> select '''Restart with Add-ons Disabled'''
Firefox will close then it will open up with just basic Firefox. Now do this:
-> Update Firefox to the latest version by going to Help Menu -> About Firefox -> click '''Check for Updates''' -> if an updated version is found then download the latest version and install it. After that follow these steps:
-> go to View Menu -> Toolbars -> unselect All Unwanted toolbars
-> click the Favicon on SearchBar -> click '''Manage Search Engines''' -> select all Unwanted Search Engines and click '''Remove''' -> click OK
-> go to Tools Menu -> Add-ons -> Extensions section -> REMOVE All Unwanted/Suspicious Extensions (Add-ons) -> Restart Firefox
You can enable your Known & Trustworthy Add-ons later. Check and tell if its working.

SPSecurity.RunWithElevatedPrivileges Not Working for Read Only Permissions Users

I have the following code in a method that generates tabbed web parts on any page in SharePoint 2010.
The problem is that it will not work for users who have Read access only on a SharePoint site. It will work when those users have Contribute access.
So even though I have elevated permissions in the code it does not actually elevate the permissions at the point where it is needed.
if (panel != null)
try
using (SPLimitedWebPartManager wpManager = SPContext.Current.Web.GetLimitedWebPartManager(HttpContext.Current.Request.Url.ToString(), PersonalizationScope.Shared))
try
// Elevated previleges required for EXPORT and IMPORT. Else Users with normal read access will get errors.
SPSecurity.RunWithElevatedPrivileges(delegate()
// Retrieve the web part titles in the ConfigureTabs XML string for this tab.
var webPartTitles = from t in xDocument.Descendants("webPart")
where (string)t.Parent.Attribute("name") == (string)e.Item.DataItem
select (string)t.Attribute("title");
foreach (string wpTitle in webPartTitles)
foreach (System.Web.UI.WebControls.WebParts.WebPart webPart in wpManager.WebParts)
// Find the matched closed web part in WebParts collection
if (webPart.Title == wpTitle && webPart.IsClosed == true)
string errorMessage;
//ADD EXPORT PROPERTY
webPart.ExportMode = WebPartExportMode.All;
MemoryStream stream = new MemoryStream();
XmlTextWriter writer = new XmlTextWriter(stream, System.Text.Encoding.UTF8);
// Export the closed webpart to a memory stream.
wpManager.ExportWebPart(webPart, writer);
writer.Flush();
stream.Position = 0;
XmlTextReader reader = new XmlTextReader(stream);
// Import the exported webpart.
System.Web.UI.WebControls.WebParts.WebPart newWebPart = wpManager.ImportWebPart(reader, out errorMessage);
reader.Close();
writer.Close();
// Show the imported webpart.
panel.Controls.Add(newWebPart);
break;
catch (Exception ex)
// For debugging use only.
Label label = new Label();
label.Text = "Please check your XML configuration for error. " + Environment.NewLine + ex.Message;
panel.Controls.Add(label);
catch (Exception ex)
// For debugging use only.
Label label = new Label();
label.Text = "Please Check SPContext.Current.Web is not null. " + Environment.NewLine + ex.Message;
panel.Controls.Add(label);
This snippet of code was originally pulled from a microsoft technet article on creating Tabbed web parts "the correct way" but it doesn't work in all scenarios.
Is there a way to get this code working for Read/Visitors to a SharePoint site?

From initial observation what I see is that your SPLimitedWebPartManager is not created from an elevated web. Try like below
SPSecurity.RunWithElevatedPrivileges(delegate()
using(SPSite elevatedSite = new SPSite(SPContext.Current.Site.ID))
using(SPWeb elevatedWeb = elevatedSite.OpenWeb())
using (SPLimitedWebPartManager wpManager = elevatedWeb.GetLimitedWebPartManager(HttpContext.Current.Request.Url.ToString(), PersonalizationScope.Shared))
{ //Rest of your code
