I cannot close a tab by clicking on the "x" - nor can I open a tab from the tab bar

On the tab bar, FF opens multiple "new tab" tabs. No matter what I do I cannot close these tabs, or any other tab, by clicking on the "x". Also, I cannot access these tabs by clicking on them.

Note that the X is a close button and that the new tab button is styled as a plus (+) sign.
You can find the New Tab button showing as a '+' on the Tab bar. 
You can open the Customize window and drag the New Tab button that shows as a plus sign (+) from the Tab bar on another toolbar and it will become a regular toolbar New Tab button. 
If you can't find the New Tab button then click the "Restore Default Set" button in the Customize window. 
If you want the New Tab button at the far right end of the Tab bar then place a flexible space to the left of it. 
You can check for problems with the localstore.rdf file.

When alt + tab between applications firefox freezes to a black blank screen and will not move. The only response it will allow is the close option after right clicking on the task bar in English

I normally have several applications running at the same time, some of them are running 24/7/365.
When accessing the applications its easier to alt+tab between them. On the occasions that I can actually get Firefox to open and stay open it always freezes and remains immovable on the screen after switching to another program.
Firefox goes black except for the border and the close button at the top right. The other buttons disappear. Even after waiting for a period of time it does not clear.
The freeze can occur either on the first switch or second switch. However, it always happens.

Have also since found out that to start FF4 in safe mode you just hold shift whilst double-clicking the icon. We only find these things out after the event, murphy's law!

Firefox either closes suddenly when I click on the address bar after startup or it hangs and also blocks internet explorer from loading

On my Windows XP sp3 system the current the last two releases of Firefox both exhibit the same behavior. When I launch Firefox it will either shutdown within seconds with no crash reporter or other error logged or it will hang completely and indefinitely. When it hangs it also blocks internet explorer 8 from loading. I have tried and followed all the steps in the crashing FAQ including safe mode, uninstalls, re-installs, profile deletes (even the profile dialog closed suddenly). I use Norton Internet Security version 18.6.0.29. A full virus scan does not find any problems. I have disabled all toolbars, plugins and addons and the problem persists. Google Chrome, Internet Explorer and Opera all work fine. Only occasionally does Firefox load and keep running. It's as if it is failing on some check at startup and either crashes or hangs most of the time.

That is a Flash Player that plays an MP3 file.

Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

Cannot close my tab, everything run well but closing my tab

Suddenly I cannot close firefox tabs, I opened some tabs and click red X button but nothing happened. I can click menu, it run well, download, it run well, back button it works, bookmark button, it works. But one thing I can't do, it's closing tabs, all tabs.

Thanks guigs2. I knew closing firefox is the only way. but it's annoying if i should close firefox everytime it happen.... ):

Cannot close first tab (LH end one) with other open ones are closeable.

Cannot close first tab (LH end one) but others are closeable. Downloading indicator on tab continues to rotate indefinitely - windows under all tabs operate normally.
Opening an additional Firefox copy allows all tabs to work normally within that copy

I had this same problem for some time now. In another Mozilla Firefox forum page related to this search one user said to disable the add on "Invisible Hand". I did that and rebooted and have multiple pages open now with multiple tabs and I could shut down the first tab on all the open windows. I think the "Invisible Hand" add-on s the culprit, at least in my case.

All of a sudden I can no longer open tabs by clicking "+" or right clicking on the tool bar. To open a new page, I have to open a whole newFirefox window. How can I fix this?

Also, Firefox crashes frequently. Is there a fix for this also?

Uninstall the Ask toolbar and it should work again. There is a compatibility issue with the Ask toolbar and Firefox 3.6 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
For the second issue, the [[Firefox crashes]] support article may help.

HT4710 iphoto will not close down when i click on the red X button

iphoto will not close down when i click on the red X button

Right (Command) click on the iPhoto icon in the Dock and see if you can select Quit there or if you get an iPhoto not responding message. If you do get that message you'll have to the the  ➙ Force Quit... menu option then figure out why iPhoto is stalled.

How to I stop safari from automatically resizing the bookmark bar when I click on the search bar?

there is probably an eloquent way to ask this but I don't even know what the feature is called.
Here is what it's doing:
I'm using safari in landscape mode on my iPad.
I click on the search bar and then the bookmarks come up below.
It takes a second to automatically resize to a size that make no sense, usually cutting off bookmark titles...and the delay of it resizes drives me nuts.
Safari did not used to do this until I guess ios 8. Any ideas how to stop this annoying "feature"??

Try deleting the Cache.db...
Quit Safari.
Go to ~/Library/Caches/com.apple.Safari/Cache.db
Move the Cache.db file from the com.apple.Safari folder to the Trash.
Relaunch Safari ...
You may want to try the Safari Reading List as an alternative to tabs.
Click the eyeglass icon just to the left of the Bookmarks icon top left side of the Safari window.
Drag the url to the window or click Add Page

Why can't I click on the window bar in quicktime X windows?

For some reason, I can't click on the window bar at the top of movie windows in Quicktime X. When I do so, it acts as if I'd clicked on whatever was behind the movie window. This means that I have to close windows with the keyboard rather than clicking, for example.
This started happening before I upgraded to Mavericks, and continued after. Reinstalling the OS did nothing.

Did you use the Migration Assistant updater before you installed Mavericks?
I ask as a resident problem that follows one across a system upgrade usually comes on the heels of a data migration. (I was vexed right up through 10.6 by a migration of data from Panther!)
If so, backup all your files and do a clean install. It would be easier to walk you through if I knew the configuration of your Mac and whether or not you have a bootable optical disk or an image on a USB thumb drive.

I keep multiple windows opened and minimized. Sometimes when I click on the task bar to Restore, it apparently "disappears" out of view past the upper left corner. From then on, it can only be seen by using Maximize. What can be done to move it back?

I keep multiple windows opened and minimized. Sometimes when I click on the task bar to restore one, it apparently "disappears" out of view beyond the upper left corner of the screen. From then on, it can only be seen by using Maximize in the task bar. When Restore/Move/Size are clicked, the pointer just goes to the upper left corner of the screen with all combinations of clicking/dragging having no success. What causes this, and what can be done to move it back?

If a window disappear then using the system menu can make it reappear or make it possible to move that window in view. I don't know what causes it to make the window disappear in your case if it does work correctly if you start Firefox.
You can check the browser.link.open_newwindow prefs on the about:config page if you want to open all links in tabs in the current window.

This is iweb development where after publishing, things look different in IE than other browsers. U r correct that this is due to IE software but is iWeb related. After all, one uses iweb not to just publish in Safari but for all browsers.
Which means that you are only considering half of the problem, but that's your choice.

I can't scroll by hitting the space bar, or clicking on the scroll bar itself, or even use the scroll arrows- how do I make them work again?

I wake up, unhibernate my laptop and suddenly I can't scroll by hitting the space bar, or clicking on the scroll bar itself, or even use the scroll arrows. In other programs it works fine. What happened and how do I fix this?

When I click on the address bar to search for a site I have already been to, the address back quickly flickers so I can't pick an address. What can I do to fix?

When I click on the address bar it quickly flicks on and off. Same happens if I click on a password or username field.

Usually the Window menu allows you to adjust window placement in Microsoft Office products.
If not, connect an external display or projector and change the resolution to the maximum.
Save the document with the window residing on the main screen with the Dock.
That will force it to open on the main screen in the future.
