Can no longer open a new tab for one window browsing

I used to be able to open a new tab without having to open a new firefox window. I can no longer do this. My Firefox version is:
3.6.73

Start Firefox in [[Safe Mode]] to check if one of the add-ons (Ask.com toolbar) is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.
See:
* [[Troubleshooting extensions and themes]]

All of a sudden I can no longer open a new tab using either the icon on the tab bar, the keyboard short cut or the File menu option. I can open a new tab ONLY by clicking on a bookmark or link.

I can no longer open a new tab by clicking on it or by using file and new tab menu, so what do I change or reset for new tabs to work?

The tabs were working fine, but now tabs will not open when I click on the 'open a new tab + ' button, or if I go to 'file, new tab'. A new tab only opens when I click a link, but I cannot open a tab at will to start a new page. I used your troubleshooting data, but it did not help. I checked tabs settings in Options and all is checked, and I even reinstalled firefox. What do I do to reset or change settings so the tabs will open?

There is a reported incompatibility between the Ask Toolbar and Firefox 3.6.13 that causes new tabs to not open. This problem needs to be fixed by Ask; they need to update their toolbar add-on for Firefox. Until the incompatibility is fixed by Ask, you can disable the Ask Toolbar or un-install it from your system.

I can no longer open a new tab either by clicking on it or using the File/New tab command.

I used to be able to open a new tab by clicking on the plus sign to the right of already open tabs. For some reason this function has stopped working. I have also tried "File/New tab" with equal lack of success.

Try uninstalling 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.

I can no longer open a new tab in firefox

I cannot open a new tab in firefox. If I click on a link, a new tab opens, but if I use the new tab button or control t nothing happens. I used to be able to open multiple tabs, but suddenly this changed. Can you tell my why?

Why can't I open a new tab for the same website? Want to disable 'switch to tab'.

I used to be able to open multiple tabs for the same website on Firefox 3.xx. I could download files from one tab and work from another. How can I disable the 'switch to tab' function?

You can disable it by using the Switch to Tab no more add-on - https://addons.mozilla.org/firefox/addon/switch-to-tab-no-more

I can no longer open a new tab by clicking on the next one to the right?

I was always able to do this until today. I rebooted the computer, now I can't. Why

The Ask Toolbar is causing that in the Firefox 3.6.13+ versions. Uninstall that extension.
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

Since the last two Firefox updates, I can no longer open a new tab by clicking on it or using the options under file (new tab). Nothing works. Please help!

Control T doesn't work either.

Can no longer move a new tab into Pinned App section in FF17

After the update to FF17 I can no longer move a new tab into the Pin As App section without first pinning the tab. I liked how it worked before, where if you put it to the front or between 2 pinned tabs it would just pin itself and place it where you told it to... Is there an option to restore this? If not, no big deal, more of a minor annoyance really.

hello andvarix, the drag&drop behaviour for tabs has changed in firefox 17 - they now move within the tab strip while being dragged. unfortunately the behaviour that you're now observing seems to be a somewhat intentional by-product of this change, it is unlikey that this will be fixed soon. you'd have to resort to the usual method of right-clicking a tab & select to pin it as app tab.
for reference see [https://bugzilla.mozilla.org/show_bug.cgi?id=787897 bug #787897] (please don't post in bug reports).

Can no longer open two Firefox tabs at the same time. Will disappear from screen but won't close - have to go to Task Bar/ Processes to close it, some links won't activate on websites. As suggested in the support area I have gone through the process of backing up my profile, deleted existing profile, removed firefox from computer, reinstalled profile in fresh folder, reinstalled firefox 6. I have done this twice for no effect - may work as it used to for a while (30mins) then gets back to its old tricks.
It is a bit irritating.

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
You can try these free programs to scan for malware, which work with your existing antivirus software:

* [http://www.surfright.nl/en/hitmanpro/ Hitman Pro]
* [http://www.eset.com/us/online-scanner/ ESET Online Scanner]
[http://windows.microsoft.com/MSE Microsoft Security Essentials] is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.

How do I get a link within a PDF to open a new tab in a web browser?

How do I get a link within a PDF to open a new tab in a web browser? Previous forums (for earlier versions of InDesign and Acrobat) mention something about JavaScript, but I'm using InDesign CC and Adobe Acrobat Pro CC
Thanks.

When you're looking at the PDF that's on your site, is it opened in the browser or directly i Acrobat/Reader? If in the borwser, do you know if it's being viewed in the browser's default PDF viewer or Acrobat/Reader? It probably won't work in non-Adobe PDF viewers.
Are you saying that when you click the link that two new browser tabs are opened with the same URL, instead of just one as you'd expect, or something else?

Firefox is adding advertising links to certain words on my website cornish-surfing.co.uk, and when I open a new tab an additional window opens with unwanted sites.
1. How can I stop these things from happening?
2. Why is it happening?
These things only happen when I’m using the Firefox browser. I use Sophos antivirus and firewall and the scans indicate my system is clean. So I’m assuming that it’s built into Firefox or there’s a security flaw with Firefox.
Can you let me know which and how I can stop it from happening?
Graham Jappé

hello, this sounds like a problem possibly caused by adware on your pc (certainly nothing that is shipping with a plain official firefox build).
please go to ''firefox > addons > extensions'' & remove any suspicious entries (toolbars, things that you have not installed intentionally, don't know what purpose they serve, etc). also go to the windows control panel / programs and remove all toolbars or potentially unwanted software from there and run a full scan of your system with the security software that you have in place and different other tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] & [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner].

I can no longer open a new browser tab by either clicking the + at the end of the last browser or by using the Ctrl key + T, how do I fix this?

I have uninstalled firefox and reinstalled firefox to try and solve this
issue, but it has not fixed the issue. To open a new tab I must right click
any current page link to get a new browser tab and then navigate to a new web address. This is a recent issue that just started happening and I can't figure out what happened or what got disabled. Please help me fix this.

Try uninstalling 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.

Why can't I open a new Tab with the "Plus" sign or "Command-T"?

If I want to open a New Tab, I either press "Command T" or select "New Tab" from the File menu, or click the little "plus" sign in my Tabs bar - - - right? None of them work. What am I missing?

This problem in is Firefox on your Mac?
May users have discovered this problem is caused by Conduit add-ons, such as a Conduit plugin and/or a "Community Toolbar" extension.
You can check for and disable extensions on the Add-ons page. Either:
* Command+Shift+a
* "3-bar" menu button (or Tools menu) > Add-ons
In the left column, click Extensions. Then, if in doubt, disable.
Often a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.
Does that help with the "+" button? If so, could you name the specific extension that caused the problem?
You might also check the Plugins section of the Add-ons page. You can use "Never Activate" to disable plugins that you don't ordinarily use.
