Firefox29 cannot close or switch tabs on OSX10

clicking on a tab no longer switches to corresponding tab window
no way to close tab; the 'x' is gone and right clicking the tab just shows the customize menu for the browser
this rendered it unusable for me and I had to switch back to FF 28

Problem with frozen / unselectable tabs applies to PCs as well, the extension that was affected by Firefox 29 is
 '''[https://addons.mozilla.org/firefox/addon/how-many-times-can-i-back/ How Many Times Can I Back?]''' :: Add-ons for Firefox
You will have to disable the extension for now. I see you went back to Firefox 28 (a lot easier on your health). It was really a pain trying to switch tabs strictly through the "List all tabs" drop-down, and use Ctrl+T, and Ctrl+W (or for you with the Mac Cmd key ⌘ ).
I had the same problem, it is now reported in
 [http://kb.mozillazine.org/index.php?title=Problematic_extensions Problematic extensions - MozillaZine Knowledge Base]
Firefox 29 made changes to Tabs, and removal of the Addons Bar. since you also show Status-4-Evar in your "MORE SYSTEM DETAILS" you use the Addons bar and have a problem there as well. You also have another extension one with the word "tab" in it "Old Firefox Tab 1.0" which could be affected as well.
Either of these extensions will restore the addons bar, I prefer
[https://addons.mozilla.org/firefox/addon/the-addon-bar/ The Addon Bar (restored)] which I prefer because I have tabs on the bottom.
Those who can stand tabs on top and the hugh Firefox button may prefer [https://addons.mozilla.org/en-US/firefox/addon/classicthemerestorer/ Classic Theme Restorer (Customize Australis) :: Add-ons for Firefox]
 I see you did try that when you were on Firefox 29.
Both extensions preserve "Ctrl+/" shortcut to toggle the Add-ons bar.
To restore Tabs on the bottom (in Firefox 29)
 [https://addons.mozilla.org/en-US/firefox/addon/fdgueux-tabs-on-bottom/ Tabs on Bottom (Australis) :: Add-ons for Firefox]
If you look in your "'''MORE SYSTEM DETAILS'''" in the right hand panel you can see what see of the extensions and plugins that you have. For instance
 '''How Many Times Can I Back?''' 0.2.2011012001 ([email protected])
 '''Old Firefox Tab 1.0''' ({b4b3e886-52d2-11e3-b4ad-f2ea6188709b})
 '''Status-4-Evar''' 2013.10.31.22 ([email protected])
I'm working through my own problems and will be able to use Firefox 29 even though some of my toolbar buttons are almost invisible (only my own styles are affected by that).

I CANNOT CLOSE THE FIRST TAB WHEN I SEARCH FOR SOMETHING AND CLOSE A SECOND TAB IT WILL NOT LET ME CLOSE THE FIRST TAB

I CANNOT CLOSE THE FIRST TAB AFTER I TYPE IN A SEARCH
== This happened ==
Every time Firefox opened
== I UPGRADED TO 3.6

I have the same problem and tested it in Safe Mode, and did the disable the add-ons thing. Everything went OK, even up to the last add-on. There wasn't a hint of the problem anymore, so I went back to regular use of FF (3.6.12) again. WELL, THE SAME THING HAPPENED AGAIN!!! I agree with the person who said that your supposed troubleshooting is B.S. You blame the user instead of saying something useful like "OK, we heard you (and over two dozen others) and we know it's not your doing, and it's OUR PROBLEM, and we're going to look into it and figure out how to fix it, AND we'll get back to you when we do and tell you how to fix it too." THAT's the kind of answer we FF users want to hear, not some claptrap about how WE the users didn't try hard enough to fix it on our own!

Cannot close or open tabs successively by one middle click

Hello,
I cannot close, or open tabs by just one middle click on every tab. It is like if there is a timeout before it opens or close a new tab again, or I have to double click with middle button.
I have taken a look in about:config but found nothing that indicates such a feature.
Thank you

You should absolutely never get a pop-up for The Safe Mac or the AdwareMedic websites.s.
Tom,
After reading through what I presume is your website, which is highly informative and very well written by the way, I come away with the impression that you really have a firm understanding of the dirty things that can go on inside your machine and how they manage to exploit certain vulnerabilities.
With respect to pop-up ads and Safari, I have a question that you may able to answer. Three parts:
(1) How are they managing to get around all reasonable methods to block pop-up ad scripts? One would think that your browser ought not perform automatic script functions (like opening a new page ... or several) without your doing anything.
By example, I'm on several forums and if I am sent a PM a notification pop-up will appear. Since I have Adblock software enabled, clicking OK will not send me directly to my inbox or open a new page as it would normally. In other words the software is actively blocking the re-direct script. Perfect. But if I go to some random website, especially ones that stream out of market Sports telecasts, it turns into a pop-up festival.
(2) Not even blacklisting certain URLs in AdBlock or trying to wildcard a URL in the blacklist stops them. Is there another method or tool you recommend?
(3) What is MacKeeper and why does 2 out of every 5 pop-up ads ask me to try MacKeeper. I swear, I'm surprised someone hasn't tired DDoS attack their website out of frustration from the way they invade your web experience.
Sidenote: Thank you creating AdWareMedic. I installed it this morning and ran a scan. Fortunately the report was clean, but I'll be adding this to my monthly system health check and clean-up.

If I cannot "go back" when using a website I cannot close that specific tab and have to close them all. I have had to restart from scratch several times today . Having a choice of closing the last tab only would be very useful. Why can't I?

After I browsed a page in a websit, I could not close that page by using the X in the rt. hand top corner as when I did this Firefox told me that it would close all tabs. It was the only way out so I closed them and started from scratch.

mratlasdreamz,
which app are you running when you get the annoying chime as you try to correct a typo?
If you’re sure that you have a 2.4 GHz Core 2 Duo CPU and 2 GB of 667 MHz RAM, then what you have is not a MacBook Pro, but an Early 2008 MacBook (did it really cost £2000 then?) — and with that model of MacBook, you could upgrade to Lion. Whether you stay with Snow Leopard or upgrade to Lion, you might find that upgrading your RAM from 2 GB to 4 GB could be helpful.
You can confirm which model you have by selecting About This Mac on the Apple menu, clicking the “More Info…” button, then clicking on the “System Report…” button, and looking at the “Model Identifier” value in the Hardware Overview section. If you have an Early 2008 MacBook, then the model identifier will say “MacBook4,1”. If it gives a different model identifier, then include that model identifier in your reply, and we can determine which model you have, and which CPU and speed of RAM it uses.
Note that Firefox 26 still supports Snow Leopard, and that Mozilla makes no CPU recommendations for Firefox on OS X other than “an Intel x86 processor”.

How can I close the current tab in Firefox v 17.0.1?

I have used Firefox for years and have always used Tabs instead of opening new windows. I have always been able to click the little "X" on the right side of the tab to close it. I am finding now that I cannot close the current tab by doing this. I have to click on another open tab and then click on the other tab I wanted to close.
I have looked through the Options many times trying to see if there is a setting I need to change, but have not found anything.
Is it possible in this version of Firefox (v17.0.1) to close the current tab?

I started Firefox in SAFE MODE and the problem went away. I checked for updates and all were up to date. I then restarted Firefox and it worked fine. Since I didn't really do anything, I am curious as to why it is now working as expected. I am glad, but still curious.
Thank you.

Close the last tab without closing the firefox app

greetings!
1.I would like to close the last tab without closing the app. The behaviour I expect is the app to open a new blank tab when I close the last tab. Currently I cannot close the last tab which already has some website opened in it.
2. When I open a new tab, i'm forced to enter a website address. I expect to the app to simply open a blank new tab & leave it to me whether to enter a address or not.
Thanks for your support. I love firefox for Android.

well, I would prefer to leave it to the end user whether he wants the awesome screen while pressing a new tab button/ or open a simple blank page. Let him choose it in the config.
regards,

Firefox keeps locking up. Whatever tab I'm in says "Connecting" with the circle rotating. Cannot switch tabs, close tabs or close Firefox. Must kill with taskmg

Problem looking likely to be malware.
I have asked this question before. I thought it was tied to the website of my local newspaper since that seemed to be where it happened all the time. Tonight I was not on that site. I was in Tools>Add-ons, trying to switch from Plugins to Extensions when it locked up. Symptoms are the current tab will scroll up and down but no links work. No other tabs can be accessed. Tab cannot be closed. Tab shows "Connecting" with rotating busy icon. Firefox must be killed with the task manager. People have suggested deleting cookies and history - no effect unless I'm supposed to perform that action every few seconds in which case it's useless. Another suggestion was to deselect "Use hardware acceleration" in Tools>Options. Also no apparent effect. I thought it might be related to Flash because I was getting a lot of messages about a plugin container not working for that. I disabled Flash and got the "Video without flash" add-on (what a POS!) which doesn't appear to work at all. Any help would be appreciated. I'm getting tired of killing Firefox a dozen times (or more) per day and may have to investigate another browser (Ugh!).

After posting this question I went back to what I had long thought to be the problem website ( www.denverpost.com ) and was looking at the comics when it locked up again. HELP!

Cannot switch tabs past a tab viewing a PDF

When I have a tab open with a PDF in it (using Adobe Acrobat 9.3.0.148 plugin) I cannot switch tabs using Ctrl-Tab and Ctrl-Shift-Tab past that particular tab. Ctrl-W won't close the tab with the PDF in it either. It looks like if you dont click within the PDF document or one of the viewer plugin toolbars etc it will let you tab past, as soon as you click within the PDF it no longer works, even if you change to a different tab and then try going past it again. Using the mouse scroll wheel to scroll through the document does not cause this behaviour to kick in either. Also in this state you cannot use Ctrl-F when you tab onto the PDF tab unless you click on the PDF itself (same goes for cursor keys and page up/down keys). FF2 used to allow you to tab past the PDFs without any issue, i noticed this on 3.5.1 while upgrading to 3.6.3. So its like keyboard focus is lost somewhere between FF and the PDF plugin.
I remember in FF2 you used to get a faint rectanglular highlight within the tab so you could tell the focus was on the tab not within the page. Thats also gone now.
I havent been able to find an existing bug specificaly on this issue, or any other potential work arounds. So just want to check before i log a bug, of course this could be an Adobe plugin issue, although it does appear to be linked with how the focus is maintained on components within FF.

Crashes on Tab Switch, Tab Close, or Quit

I've been working with STP for a few months at my school and I really like it, but recently I'm having a real pain of a problem with some of my STMP files.
Whenever I open multiple tabs, whether double-clicking on an audio file in the multitrack editor or just opening a new tab, if I try to close the new tab or switch to another tab or even if I try to quit the program, I get the beachball of death. It doesn't matter what I do in the new tab...in fact, even if I do nothing at all to it, just open then try to close, it crashes. I have to force quit every time and it's very frustrating.
I've tried deleting (app, prefs, any file labeled with STP in its name) and reinstalling, repairing disk permissions, but nothing works. Again, this doesn't happen with all my STMP files, but a lot of them have this problem. Can anyone offer some advice on this?

Hi Arklop,
Hmm I'm not seeing this.
Just to check, are you definitely running the Universal Binary version of Soundtrack Pro? Also, how much memory do you have?
Where is the app crashing? Why don't you post the crashlog on this forum--maybe someone on the forum will have an idea what's going on.
What audio device are you using? Do you get the same results if you just use the built-in audio interface?

Cannot Close Tabs in Minefield That's Running Flash

Just wanted to report a bug I've been noticing. I'm using Minefield (64-bit) prerelease 4.0b7pre and when I have a tab open that has 64-bit flash running in it, I cannot close the tab anymore. I need to close the entire browser instead. This is repeatable regardless of the websites I visit, e.g. Stormpulse.com, Weather.com, Youtube.com.
Thanks,
Cythth

Press apple shift and delete
If that does not work try this:
click on Finder in the lower left corner.
Then, in the top left corner click on the word finder
Scroll down to "Secure Empty Trash"
This will delete any file that may be open.

On a Mac, how do I close tabs or windows where dialogs have popped up trying to download malware and you cannot close them?

On a Mac, how do I close tabs or windows where dialogs have popped up trying to download malware and you cannot close them? I think it's Ctrl+F4 on a PC. I would like to close just these tabs or windows instead of having to quit the whole firefox program.

The equivalent of Control+F4 is Command+W, I have not tried it but you may still get the alert boxes when closing a tab using this method.
The AlertCheck add-on can be used to block the infinite loops such as this - https://addons.mozilla.org/firefox/addon/alertcheck - This functionality is built into Firefox 4.
An alternative method in Firefox 3.6.* is to temporarily turn off JavaScript. Open the Firefox preferences window, go to the Content panel and de-select the setting "Enable JavaScript" then click OK. You will then be able to close the tab, and can then re-enable JavaScript.

After a crash all open tabs disappeared - but in the background one website with audio is open. I cannot close it, because it appears as if no tabs are open.

My browser froze & reopened with all tabs closed. I couldn't restore the tabs. Since then, when I open the browser, one tab I had with a video keeps playing - but I cannot see & therefore cannot close it.
I have tried restarting my laptop & I deleted all history/cookies/..., but nothing helped yet.
This is very annoy, please help!

Cannot close multible tabs, system freezes and have to close firefox, but when i have multible tabs open ,cannot close individual tabs.

after Firefox is loaded and open ,I open another tab. I can view the site but when finished I cannot close the tab and if I open other tabs I cannot close them either when finished, I have to close Firefox and reopen Firefox.

hi thanks for that info,but I tried the first help email I received and that one did the trick.Tahanks again for your in put.

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.
