Some websites change my browser how do I stop this

When I updated firefox the delta search was installed in spite of my attempts to block it. It changed the browser to this from google.

delete the user.js file and use the search reset tool.

Whenever I open a new Firefox Browser, the other Firefox Browsers that I have minimized to the bottom of the screen all restore, (reopen up) onto the screen with the new opened Firefox Browser, how do I stop this? Just want the new one to open on screen

Whenever I open a new Firefox Browser, the other Firefox Browsers that I have minimized to the bottom of the screen all restore, (reopen up) onto the screen with the new opened Firefox Browser, how do I stop this? Just want the new one to open on screen and the existing stay minimized.
== This happened ==
Every time Firefox opened
== I think when a I updated or downloaded a newer version of FireFox at Firefox's suggestion.

Hmm that does sound a bit strange - I use a system quite similar to yours (XP, FF 3.6.3), and don't see this behaviour.
I would recommend trying to start Firefox in Firefox [[Safe Mode]] (make sure you close '''all''' running Firefox instances first), and see if this problem persists.
If not, it could be some add-on causing this behaviour - restart Firefox in Safe Mode, disable all add-ons, and enable them one by one to find the guilty one.
If it still happens in Firefox Safe Mode, some other program (or something in Windows itself) most likely is the cause. We may be able to help with this too, so let us know what works and provide as much additional information as possible to let us help you solve this.

I used Iolo to "clean" my hard drive, and now I can't access some websites, including facebook. How can I fix this? I get what looks like a root directory.

Since using Iolo yesterday, I can't bring up the full front page of some websites, including Bing. Bing is a grey, blank screen. Lumosity looks like part of a root directory. How can I fix this? I'm trying to use IE instead, and having problems with that, too, and I don't like it anyway.

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.

Extra home page opens when I click on links in websites or emails. How can I stop this?

With Firefox running or not running, whenever I click on a link on a web page or in an email, two Firefox pages open: the page in the link, and my home page. How can I stop the extra home page from opening?

closed firefox, then did yum reinstall firefox
didn't help, same problem

Firefox opens a dialog box when I use the browser, "Checking add-ons for compatibility..." then open the Firefox start page along with my homepage. I do not want the Firefox page when I open the browser. how do I stop this?

Since Firefox updated it checks add-ons every time I open Firefox. The Firefox homepage then opens along with my home page, two tabs. I want the checking to stop. This has not happened before--only with this update.

This question was reposted and replied to here:

Firefox keeps opening up a new window with "index of file///c /program files/mozila firefox" as I'm browsing, how do I stop this?

every time I open firefox after about 2 minutes a new window pops up with 2 tabs, one saying problem loading page, the other shows a list of program files, thier size and when the were last modified. When I close it, it pops back up again in a few minutes.

If you get a program called malware bytes it blocks that window from popping up. Hope that helps :)

When I upgraded from v4 to v5 my bookmarks was lost. I do have the one that is in the firefox toolbar. Apparently I had a bookmarks add-on. V5 changed my browser how can I determine what the program was and if the bookmarks are still there?

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).

I use Firefox as my default browser but, on any site, keep getting some words underlined in green from which an ad pops up. Really peeing me off! Doesn't happen on IE or Chrome. How can I stop this?

From what you have described, I don't think you are ever going to pick that up as malware at all. But I did look at the site you mentioned in Google Chrome, and in IE9. First thought was maybe Chrome suppresses it, but that would be contrary to trying to convince you that their AdSense or IntelliTXT is "helping" you.
What I did find in Chrome was
"Google Chrome's connection attempt to ad-apac.doubleclick.net was rejected. The website may be down, or your network may not be properly configured."
Since I don't have ad blockers in Chrome or IE, that tells me that my hosts file is doing its job, you can draw you own conclusions. There is something similar displayed in IE, but I can't read what was there because the font-size was too big. for the space. In Firefox with "Adblock Plus" extension it is all wiped out. The hosts file works across the entire system but is directed at blocking malware sites more than advertising. "Adblock Plus" is very good at blocking ads and can do its blocking with more generic filters, and can block a lot of malware from coming in but it can't block at the system level that a hosts file can.
In IE although I can only see "It appea" because the font is too large and text does not wrap it does actually say "It appears you are connected to the Internet, but you might want to try to reconnect to the Internet."
I would certainly suggest installing "Adblock Plus" extension and the "Easylist (USA)" filter subscription -- links are in the links previously provided, and installing the hosts file as well also in the links.
It takes a bit more work to install and maintain a hosts file but the directions should be clear enough.

I have changed my Apple ID from an old email to a new one. But It keeps coming up with my old email and asking for my old password. How do i stop this from happening and get it onto my new one?

I have changed my Apple ID from an old email to a new one. But It keeps coming up with my old email and asking for my old password. How do i stop this from happening and get it onto my new one? Its on my Ipad and iphone 5, please help as its doing my head it

Every single website, or link within a website page is being added to my location bar/address bar drop down menu. How can I stop this? This just started happening.

Every single website url address, or url address within a website page is being added to my location bar/address bar drop down menu.
I don't want everything added or saved in the location bar. Only urls that I used a lot used to be saved there but now every single url (and url within a url)I visit is being added to it.

I'm sure it's a simple browser setting but I've checked and nothing gives an option to control this.

A possibility is to open the links via the right-click context menu or a middle-click in a new tab to make sure that Firefox sees them as regular links.

All the pages I visit are being bookmarked under Unsorted bookmarks. This is a breach of privacy since anyone can check my browsing history. How do I stop this?

Firefox doesn't bookmark pages automatically to the Unsorted folder unless you click the star on the location bar.
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).

Hi dfrost10,
I wouldn't be surprised if you were hit with some [https://support.mozilla.org/en-US/kb/Is%20my%20Firefox%20problem%20a%20result%20of%20malware?s=malware&r=0&e=sph&as=s#w_how-do-i-get-rid-of-malware Malware]. I'd probably investigate that first.
If that isn't the case, you should take a look at the Knowledge Base article [[How to set the home page]]. Your homepage might have been changed by a particular site. Sites like MSN, Yahoo, etc have been know to ask to become your homepage.
There are steps in that article to reset your homepage preferences to default. I would try that first to clear out any strangeness. If that works, you can try setting your homepage again to your personal preference.
If that doesn't work you should look at the article [http://kb.mozillazine.org/Preferences_not_saved Preferences not saved].
Hopefully this helps!

The website recommending that I download Codec Performer opens in a new window about every 10 seconds. How can I stop this?

A website recommending that I install Codec Performer opens a new window about every 10 seconds. How can I stop this?

One potential cause of this is an unwanted extension. Try disabling ALL nonessential or unrecognized extensions on the Add-ons page. Either:
* Ctrl+Shift+a
* orange Firefox button (or Tools menu) > Add-ons
In the left column, click Extensions. Then, if in doubt, disable.
Usually 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.
If you are adventurous about installing software from various websites, you may have loaded a bundle that contains some, well, crap. To review recent additions, go to your Windows Control Panel, Uninstall a Program, and click the "Installed on" column heading to bring the most recent items to the top. Remove anything unexpected or unwanted.
Success?

I just started getting the error message below - when I drag a file to TRASH, I get the message "Finder wants to make changes. Type in your password to allow this. Why ? and how to to stop this request ?

There should be nothing native to the OS X which would ask for a password
or other information on a restart, unless accompanied by the traditional login
box with your user name.
There are adware or marginal products that could be called malware (bad)
that would impose their presence and some items that could have been
downloaded by accident or through some corrupted free software site; of
those some could ask for and gain permission to go through your Mac
and maybe even run in the background to do other nefarious misdeeds.
You could see if startup in SafeBoot allows you access past that the Completer.
Since I don't have a pile of helpful article links on how to resolve various issues
I'd be looking them up one way or another.
There are some helpful items in the site http://thesafemac.com - see Tech Guides
listed (adware, malware, & performance) plus a link to the adwaremedic page.
Also, Apple support has a helpful page on how to remove adware and other bits:
•Remove unwanted adware that displays pop-up ads and graphics on your Mac - Apple Support
Hopefully this helps somewhat.
Good luck & happy computing!

Each time I start FF tabs from previously visited websites automatically propagate. How do I keep this from happening?
