You can also create a new profile as a test to check if your current profile is causing the problems. 
That will allow you to revert to the original profile if it didn't help or you are able to identify the cause.
See "Creating a profile":

If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.

Since updating last time Firefox will not open new tabs unless I right click on a link. It won't open them via file or the tab at the top of the brwoser. Anyone know how to fix this?

Since updating last time Firefox will not open new tabs unless I right click on a link. It won't open them via file or the tab at the top of the brwoser or usinf ctrl + t. Anyone know how to fix this?

I can press ctrl for a new tab but otherwise a new tab does not open. I actually need help regarding this new Synch which apparently will be in Firefox automatically in an upcoming version so I am asking how that will synch with people who use LastPass-of course because I use this very successfully and really am not eager to change the set up that I have in place at this time.
I have read through endless FAQ trying to find anyone else who has this question or concern but have found nothing. Can you please tell me how that service will get along with LastPass which does basically the same thing as Synch-it is probably spelled wrong as it looks wrong to me but if I click back to where this issue began, I will lose all of this question so please respond for the upcoming service synch.

I have a new MacBook Pro. I am using firefox, but my homepage is set to google. Firefox constantly keeps opening new tabs to its own homepage by itself. How can I disable this feature?

I have a new MacBook Pro. I am using firefox version 7.0.1, but my homepage is set to google. Firefox constantly keeps opening new tabs to its own homepage by itself. How can I disable this feature.

Hi [email protected]
If you have set Google to be your homepage, that should be the first one to appear. Are you seeing the Firefox home page when you open new tabs? New tabs should be blank by default. The only reason I've seen Firefox open new tabs with Firefox data on it is after an upgrade of the product.

I just reinstalled firefox, when I open new tabs it opens internet explorer, but the firefox ICON is in the top left

Do you have an extension like IE View or IE Tab that opens pages in Firefox sing IE as the rendering engine?

I installed the latest version of Firefox and it opens to google. I would like to use my old Sbcyahoo home page as the default page. How do I change

I installed the latest version of Firefox. The home page is now a google search box. I would like to use my old sbcyahoo desktop with its icons. I am unable to make the change.

Oops. I could have been more clear, sorry.
TOOLS > OPTIONS > GENERAL tab
Under Start-up at the top of GENERAL, you have an option to type in the url or use the tabs to set your homepage to the current page.
Go to your chosen site, open OPTIONS and click 'Use current page.'
Sorry for the shorthand version previously. I blame the cat.

Firefox does not open new tab

I have been using Firefox 3.6 and it works quite well, except that a week ago it stopped opening new tabs (when you click on the + sign for new tabs). Cannot find any help in the Firefox help pages.
(Before you tell me to upgrade to 4.0, I did that and it crashes at least once a day, which practically never happened with 3.6.)
I'm using a Lenovo T510t and Windows 7

Un-install the '''''Ask Toolbar''''' until Ask fixes the problem with their toolbar that is causing that issue.

Firefox will not open new 'tabs', not sure if its disabled, but does anyone know how to enable the use of my tabs?

Firefox will not open any tabs on my browser. I've tried using all alternatives to open a new tab - using the 'plus' (+) button doesn't work, 'control + T' doesn't work, going to File and clicking 'new tab' doesn't work either? Help please!

Your suggestion worked! Thanks!

How can I get Firefox 8 to open new tabs at the end?

Hi,
I know there's a way to make Firefox open new tabs at the end instead of this really annoying forced 'open new tabs next to open tab behaviour'. Can anyone help me find it?
Thanks!
Evan

You can set the pref browser.tabs.insertRelatedAfterCurrent to false on the about:config page.
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website. 
If you see a warning then you can confirm that you want to access that page. 
*Use the Filter bar at to top of the about:config page to locate a preference more easily.
*Preferences that have been modified show as bold (user set).
*Preferences can be reset to the default via the right-click context menu if they are user set
*Preferences can be changed via the right-click context menu: Modify (String or Integer) or Toggle (Boolean)

Firefox won't open new tab, have to open new window for any link.

New tab won't open both when attempting to do it by clicking on "cross" in the tabbar or from File >> new tab.
Thanks

Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe Mode start window.

Firefox won't open new tabs when I click, also he doesn't open new tabs when I use CTRL+T. Any solutions?

When I want to open a new tab, firefox doesn't do it. The problem is the same when I use CTRL+T. So I can't open any new tabs.
Nothing seems to work: restart the pc, closing firefox,...

Uninstall the '''''Ask Toolbar'''''. It can cause that problem.

Firefox won't open new tab

Firefox won't open a new tab. It opens links on a new tab but if I try to open a new tab manually it does nothing. It was fine yesterday but not today.

That can a problem with the Ask.com toolbar (Tools > Add-ons > Extensions)

Firefox crashes when opening new tab

Crash-ID: bp-681f1751-fc5b-4f14-a30b-f93ed2150407
I have tryed:
Clean install (with removing of C:prog..\mozilla)
Uninstalling and deleting extensions
Restarted Firefox in safe mode without addons/extensions.
Uninstalling/updating flash/adobe
I can start firefox, but when i press the "+" to open a new tab Firefox closes and "Mozilla Crash-report" window opens.
It seems like firefox it self can open a tab. For example when i do a fresh installation, Firefox opens with 2 tabs.
But when i want to open one it fails and Firefox shuts down. Its really wierd because i have never run in to this kind of problem before and i dont recall installing anything new before this problem showed up.

What is the setting of the new tab page?
You can check the browser.newtab.url pref on the about:config page.
You can open the about:config page via the location/address bar.
You can accept the warning and click "I'll be careful" to continue.

Thx! For some reason the string was set to "about:newtab" or something like that. Changed the name to my default homepage and the problem was fixed. Any ideas on why this happend? I didn't change it myself.
Never the less! Thank you for saving my haircolour from turning gray of frustration. Was worried i had to turn to Chrome or.... IE....

Why won't Firefox let me open new tabs?

When I click on "open a new tab" nothing happens. It was working one day and stopped the next(??). I have tried the settings, re-downloading, nothing seems to help. Thank you.

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).

My firefox won't open new tabs with the button or when I press CTRL+t, what is the problem?

I can't open any new tabs what so ever. I tried uninstalling and re-installing, and there was no change.

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.

Why does Firefox keep on opening new tabs when I log in to my Facebook account? It only stops when I cancel 4 or 5 tabs already opened.

I just opened my Facebook account today. It happened again i.e. several window tabs opened showing the same first page of my opened Facebook account. This is very annoying.
