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.

I can´t restore my tabs (and I´ve already checked the History-Recently Closed Tabs)

If, by accident, I click on the bottom part of Firefox (above Windows´ taskbar) the browser sort of minimizes and I can´t reopen it, I have to cancel everything I´m doing. As I usually work with many tabs, a pop-up asks me if I want Firefox to save my tabs for next start, and I click on "Yes", but then, when I open it, I can´t restore them at all, even if I go to History-> Recently Closed tabs...
How can I solve this???
Please, I´d really appreciate it if you could help me, because this is so annoying, and makes me waste a lot of time!

Hi Morbus,
Thanks for your quick response. I set Tools>Options>General>Show my windows and tabs from last time as you told me, but it didn´t work. I also disabled add ons and ran the Safe Mode, though I still got no solution, so this is my Troubleshooting Info:

Where is the 'History Recently Closed Tabs' menu in Firefox 29

There used to be a 'Recently Closed Tabs' in the old orange Firefox 28 menu. Now it seems version 29 only has a 'Restore Closed Tabs' menu item in its 'History menu'. There seems to be no option to restore individually closed tabs. I'm always closing a tab by accident, and the old method was very fast and easy.
Another person asked about this, but it seems his only solution was the 'Undo Closed Tabs Button' Add-On:
https://support.mozilla.org/en-US/questions/997285?esab=a&as=aaq
In the old menu, you had access to your recent history, 'Clear Recent History', 'Restore Previous Session', 'Recently Closed Tabs', and 'Recently Closed Windows' in one easy to access spot. Now all that is buried, or doesn't seem to exist anymore.
Is there any way to re-configure the new menu to include at least the 'Recently Closed Tab's menu again?

You can click History in the 3-bar Firefox menu button on the Navigation Toolbar to see the sections for recently closed tabs and recently closed windows.
You can also unhide the menu bar and open the History menu.
*Press the F10 key or tap the Alt key to bring up the hidden Menu bar.

CTRL+SHIFT+EJC doesn't work anymore

On my MacBook Pro, the above no longer works to turn the screen off. How do I enable it again?

Yeah I had that issue too i had to hit Command+Q a couple times then do the CTRL+OPTN+ESC or CTRL+SHIFT+EJC.
Good Luck; Hope this Helps -

Ctrl + Shift + T doesn't work

I am using the new Firefox Developer Edition as a stand-alone on Ubuntu, so I can still use the "old" version, too.
Everything seems to be working fine, as in I am logged in and setup sync.
However, I cannot re-open a closed tab with the keyboard shortcut Ctrl + Shift + T, nothing happens when I try.
When I click on "About Firefox Developer Edition", it shows these details:
Firefox
Developer Edition
36.0a2 (2014-12-09)
Firefox Developer Edition is up to date
You are currently on the aurora update channel.
There is already a question just like this one
https://support.mozilla.org/en-US/questions/1022757#question-reply
but the only answer does not solve it.
"browser.sessionstore.max_tabs_undo" is set to 10
"browser.sessionstore.max_windows_undo" is set to 3

Yeah I had that issue too i had to hit Command+Q a couple times then do the CTRL+OPTN+ESC or CTRL+SHIFT+EJC.

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 <b>about:config</b> page.
*http://kb.mozillazine.org/about:config
What is the value of the browser.sessionstore.max_tabs_undo pref?
* http://kb.mozillazine.org/browser.sessionstore.max_tabs_undo
* http://kb.mozillazine.org/browser.sessionstore.max_windows_undo

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.

[LAVA Cross Post] CTRL+SHIFT+ Shortcuts sometimes not working in LabVIEW

Cross-post from LAVA: http://lavag.org/topic/15619-ctrlshift-shortcuts-sometimes-not-working-in-labview/
See the above post for more information - here's a synopsis:
CTRL+SHIFT modifiers are not working while running LabVIEW in a Parallels 7 virtual machine. This problem affects both LV2011 and LV2012. I'm not certain that this is a LabVIEW bug - could be an issue with my virtual machine environment or it's configuration - except that CTRL+SHIFT modifiers work in other applications on the affected VMs. It's just LabVIEW that appears to ignore shortcuts with the CTRL+SHIFT modifiers.
Any ideas?

Any news on that?

Left shift key doesn't work on some characters

In some applications, such as Excel and AOL, my left shift key doesn't work on some letters. Consequently, when I'm typing I get lower case letters when I've typed shift plus the letter to get a cap. Right shift works OK, but I'm not used to using it. It happens on i, t, and p, I've noticed so far. I don't know if it's the keyboard or the application. Word seems to work fine.
Would welcome any ideas on what is causing this and how to fix it.

Is it possible that you have inadvertently switched to a different keyboard layout? Open System Preferences, then click on the Language & Text preferences. Within the Language & Text preferences click on the 'Input Sources'. You should see a long list of languages representing the various keyboard layouts that are available. Make sure that only the keyboard language you use is selected. If there are multiple languages selected then de-select the extras.
If you continue to have problems then check the 'Show input menu in menu bar' checkbox in the lower section of the preference pane. This will place an icon in the upper right menu bar (it looks like a flag representing the language you have chosen for your input device) that provides additional options. I suggest selecing the 'Show Keyboard Viewer' option and then try pressing the keys that you are having problems with to see how they show up on the keyboard viewer graphic. If you've set the correct language for your keyboard and the key sequences still don't match, then you may need to take your keyboard in for service. Better yet, borrow another keyboard to confirm that the keyboard is the issue.

I updated to maverick, and maybe it's a coincidence but my left shift key doesn't work unless i really press it down. Is there any way to fix this without bringing it into the Genius Bar?

Plugins usually are installed externally to Firefox. However, you can disable them in Firefox so that Firefox does not use them.
SearchReset is supposed to automate the task of resetting certain preferences, but you still can edit them manually if necessary.
'''''Address Bar Search'''''
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the filter box, type or paste '''keyword''' and pause while the list is filtered
(3) Right-click '''keyword.URL''' and choose Reset. This should restore Google as the default for address bar search.
Does that work?
'''''Search Box'''''
Usually it works to choose your preferred search engine from the drop-down. To remove an unwanted search engine plugin, usually the Manage Search Engines... choice at the bottom of the drop-down takes care of it.
Do either of those work?
There might be another way to hijack that search box; I think some of the other frequent responders probably are more familiar with it than I am.

Suddenly with version 9 and 10 i cant use the shortcut command of ctrl+shift+t to open the most recently closed tab. a feature used several times a day, previously.

Hi,
Please check if this happens in [https://support.mozilla.com/en-US/kb/Safe%20Mode Safe Mode.] This is a temporary diagnostic session and you can exit anytime and start Firefox normally again. This session disables all the '''Extensions''', themes ('''Appearance''') and '''Plugins''' in '''Tools''' ('''Alt''' + '''T''') > '''Add-ons'''.

Install update to 3.6.16. New version lost tab history, "Recently closed windows" is inactive.

I downloaded and installed the update to Firefox 3.6.16. When the new version opened, my browsing history from previous use had disappeared, only one tab was present. The [History/Recently Closed Windows] was grayed, so not accessible. Is there any way to restore my previous browsing history from a file?

Uninstall the Ask toolbar and it should work again. There is a compatibility issue with the Ask toolbar and Firefox that prevents new tabs from being opened.
There are a couple of places to check for the Ask toolbar:
* Check the Windows Control panel for the Ask Toolbar - http://about.ask.com/apn/toolbar/docs/default/faq/en/ff/index.html#na4
* Also check your list of extensions, you may be able to uninstall it from there - https://support.mozilla.com/kb/Uninstalling+add-ons

What happened to the recent history with recently closed tabs pulldown that was next to the back/forward buttons in version 5??

I noticed that i cannot access my recent history or recently closed tabs via the pulldown menu next to the forward/back buttons in the version 5 firefox. How do i do this in this new version?

Click-hold the unified Back / Forward button, or right-click it to get the Back / Forward history for that tab.
Or install this extension to get the old "drop-marker" button restored. <br />

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