When opening firefox appears blekko page

I am a Mozilla Firefox 4.0 user in Linux/Ubuntu. Since some weeks ago ( I dont know what I did) when I try to open the Firefox browser, instead of the classic Mozilla page, appears the blekko page with "BLEKKO /SLASHTAG SEARCH MOZILLA FIREFOX" as title. ( I had downloaded blekko one year ago and never used it but I can`t uninstall it).
What do I have to do in order to get rid of blekko and use firefox?
Many thanks/ Regards

When opening Firefox, I also get a popup page thanking me for installing AOL Toolbar.

Frequently, when opening Firefox 7.0.1 I get a popup page over the home page. The popup page is a Thank You for installing AOL Toolbar. I do not have the toolbar, though I might have in the past. I do not like AOL and want to stop the popup page but have not been able to. I do use Winamp's Toolbar and this could be the source of the problem. If Winamp Toolbar is the problem, I will uninstall it if there is no way to turn off the popup from there. Please assist.

There is some anecdotal evidence that the scripts on the Apple site that are supposed to detect the version of Windows you are running may fail for some users - jumping straight to the "Thank you for downloading ..." page with the installer not having been downloaded. As an alternative, you can go directly to the relevant downloads:
iTunes 12.1.0.71 for Windows (32-bit) - itunessetup.exe
iTunes 12.1.0.71 for Windows (64-bit) - itunes6464setup.exe
There is an alternative downloader for 64-bit editions of Windows here:
iTunes 12.1 for Windows (64-bit — for older video cards)
that seems to address many of the playback issues that some users have been reporting with the full 64-bit version (the alternative installer here is the same architecture as most previous "64-bit" versions of iTunes, i.e., a 32-bit application with a 64-bit installer). The "for older video cards" reference does not seem to fully define the scope of systems for which this alternative works better.
See turingtest2's notes on Troubleshooting issues with iTunes for Windows updates for more details if you're still having problems with installation. This also includes links to the iTunes 12.0 installers if the issues reported with 12.1 suggest it safer to use the previous version.

Avast detects URL:MAL when opening firefox.No issue with IE or Chrome,after troubleshooting realized problem is NoScript addon.Can it have been infected?

avast -network shield
Infection Details
URL: http://188.24.140.190/
Process: C:\Program Files (x86)\Mozilla Firefox\firefox.exe
Infection: URL:Mal

Hi Tyler,
Thanks for quick reply
Initially after some troubleshooting I noticed that I could make infection pop up disappear:
From Configure how firefox connects to the internet -> changed from "use system proxy settings" to "auto-detect proxy settings" or "no proxy"
With this option modified, the pop up from avast didn't appear any longer when opening Firefox.
However I noticed that both Chrome and IE were set to work on the same "use system proxy settings" and they weren't causing problems...so I assumed the problem still has to be with firefox.
After changing back the option in firefox to "use system proxy" I got again the notice, but saw that when opening firefox in safe mode the issue was gone again.
I tracked it to the no script addon, after removing it, the issue disappear regardless of proxy config settings...when I reinstall it, it appears again.
I am now running in depth virus scans to see were the actual infection is.
It seems to me it is expoiting a vulnerability in this addon, I will try the reset also.

I lost the Google main screen when I upgraded my firefox on one computer, but not on the other one. How do I make google my default desktop when opening Firefox?

Used to have Google come up as the search box and main page when opening Firefox. Now I get an error message, or sometimes I get Inbox. How do I switch back to Google?

When opening Firefox 6 I receive 2 JavaScript Application errors; the 1st is "TypeError: Component.classes[TvtPwmComponent_CID] is undefined". The 2nd error is; "TypeError:Components.classes[componentid] is undefined." How can I correct these errors?

When opening Firefox 6 I receive 2 JavaScript Application errors; the 1st is "TypeError: Component.classes['''TvtPwmComponent_CID'''] is undefined". The 2nd error is; "TypeError:Components.classes['''componentid'''] is undefined." and upon closing Firefox 6 I receive the following JavaScript error; "ReferenceError:'''M_caFxTBobj''' is not defined."

This issue can be caused by an extension that isn't working properly.
Start Firefox in [[Safe Mode]] to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

I Hate Bing and when I click on a Firefox NEW Tab and search I keep getting Bing results, I used to get Google which I would like back, my homepage when opening Firefox is not Bing but all tab searches retrieve Bing results.

My homepage when opening Firefox is not Bing, yet for some reason today it started using Bing instead of Google for my NEW tab search results. I already deleted Bing from the search bar, no results. Deleted Bing from my computer's control panel. I just want to be able to click a new tab and have my results in google as I always have.

hello, you have a malicious addon present on your pc. please go to ''firefox > addons > extensions'' & remove ''LyricsParty''.
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].

When opening Firefox I get a Java Scripts error message and Firefox will not always open

When opening Firefox browser I get an error message from JavaScript Application: "TypeError:components{cid} is undefined. Sometimes the Firefox browser will not open; sometimes it does. Very annoying!!
Richard

This can be caused by an add-on that says it is compatible with Firefox 4 but isn't quite compatible. This thread has more information: [https://support.mozilla.com/en-US/questions/729606 Javascript pop errors stating: TypeError: Components.classes[cid] is undefined | Firefox Support Forum | Firefox Help].
Does that help?

Not responding when opening FireFox 4.0b7

Hi there,
When opening FireFox 4.0b7 the browser hangs for about a minute and I get (Not Responding). If I use FireFox 3.6.13 I have no problems at all or if I use any of the other browsers, link IE9 Beta. What is going on?
The opening webpage we use is: www.tlc-online.co.uk/ I have changed the opening homepage to www.bbc.co.uk/ and the same thing happens.
Thanks for reading and any help you can give.

This will most likely due to hardware acceleration. There are a number of bug reports that are still being worked on to improve startup times with hardware acceleration turned on.
You can turn off hardware acceleration to improve startup times. To do that in the Tools menu select Options to open the options dialog. Select the Advanced panel, and then the General tab. Uncheck the setting "Use hardware acceleration when available".

How do I have my bookmarks appear within my home page when opening firefox

Dear Firefox,
After an embarrassing amount of frustration, I was able to sync my bookmarks from my desk top PC, to my new MacbookAir...so proud of me :) All of my 690 bookmarks are on my Macbook.
On my desk top PC, when I open Firefox, all of my bookmarks are immediately visible on the left side of my Firefox homepage which is yahoo.com. I would LOVE to have this identical manner of opening Firefox on my Macbook and seeing the bookmarks in their various folders, all on the left side of my opening homepage. As of now, I have to go to the top of my Firefox homepage and tap on "bookmarks"....I'm glad they are all there, but it would be awesome to have them displayed without the extra step. My thanks are yours,
Jeff

Thank you mha007, your suggestion has always been my "go to" when I was using my PC. Maybe I'm too "green" when it comes to my first Apple lap top....It didn't work for me when I clicked ....but here's what I ended up doing...I played....on my Macbook, I simply went to the very top Firefox bar. I went to "View", and scrolled to "Sidebar". Within "Sidebar", I clicked on "bookmarks"....and voila, it worked like a charm.
P.S. Guess what! Because of you I just tried something. On my Macbook, there is no CTRL button....there is a button that says the full word "control", and that's what I used along with "B"....it doesn't work. I just tried my Macbook button that says "command", and then tried the "B"....WOW, how easy was that....it worked! Thank you for responding to my post.

When opening Firefox my default home page is google, and it is now defaulting to Brazilian. How do I change it back to English

As noted, about a week ago when I open firefox the google home page is opening up in Brazilian instead of English.

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

When opening firefox, a banner saying downloading the latest applications appears but nothing happens.

Starting today, when I open Firefox a blue banner just under the toolbar pops up saying "Downloading the latest applications". Nothing is downloaded. I'm not sure if this is a function of Firefox or my default page Google. I tried to reload the latest version of Firefox and the problems persists.

== This happened ==
Every time Firefox opened

The code is not working because you made a mistake somewhere, duh! So figure out what (hint: firefox javascript console, it's your friend) and fix it!
And next time when you post code: use the [ code ] tags to pretty format your code, as it is now it's unreadable.
