How do I stop Firefox from opening old tabs/windows after a crash?

whenever it crashes and i try to reopen the program, it opens all my old tabs and windows. often these are videos which all start playing at once. or worse, it opens the page that made it crash in the first place and crashes again.
how do i stop this annoying feature?
if there's no way to stop it, can you recommend a simple browser that doesn't try to think for you?

hello, enter '''about:config''' into the firefox address bar (confirm the info message in case it shows up) & search for the preference named '''browser.sessionstore.resume_from_crash'''. double-click it and change its value to '''false'''.

How do I stop Firefox from opening a new window when I go to a search item?

When I do a search, and click on a topic, Firefox opens a new window on the tool bar at the bottom of my screen. How can I stop this from happening?

I'm guessing you use Google for search. There is a setting in Google search to open each result in a new window. (When you use tabbed browsing, that means each result opens in a new tab.) You can check on whether you have that setting turned on as follows:
On a Google results page, click the button on the right side with the "gear" icon, then click Search Settings from the drop-down list. At the bottom of the page is the setting to open results in a new window.
Is that the culprit?

How do I stop firefox from opening a seperate window whenever I click on a link to log into a different website with my social network account?

Whenever I try to log into a website (i.e. King of the Web.com,etc.) with my facebook account, a new window will appear behind my current window and when I click on it, it never shows up even when I minimize the current website, how do I get the new window to show so I can log in and vote for Tre Melvin? (P.S. vote for Tre!)

I think Facebook uses its facebook.net domain for this function. When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.
1. Clear Firefox's Cache
orange Firefox button ''or'' Tools menu > Options > Advanced
On the Network mini-tab > Offline Storage : "Clear Now"
2. If needed, delete the site's cookies here
Right-click this page and choose View Page Info > Security > "View Cookies"
In the search box at the top of that dialog, change the domain to facebook.net and remove the site's cookies.
Then try using the login with FB feature again. Does it work?

How can I stop Firefox from opening (to "File Not Found") when opening my Opera browser?

Ever since I installed Opera 10.61 on my new computer (Windows 7 Ultimate operating system), whenever I open Opera, Firefox opens one second later with the following error message:
'''File not found '''
Firefox can't find the file at /C:/Users/Nasheed/AppData/Local/Opera/Opera/temporary_downloads/client-en.xml.
* Check the file name for capitalization or other typing errors.
* Check to see if the file was moved, renamed or deleted.
TRY AGAIN.

This happens EVERY TIME I OPEN THE OPERA BROWSER. How can I stop this from happening? I'm stumped.
[EXTRA INFO - I was unable to enable Firefox to access my previous profile on the new computer (despite putting the old profile in the appropriate Mozilla Firefox folder. So, there are now two profiles in that location.
After reading the answer to another forum member's question, I attempted to resolve the problem using Profile Manager, but I was unable to locate the Profile Manager. The Windows "Search" feature is not enabled on my new computer (nor can it be enabled from the Customize Start Menu options).]

Thank you for your response, Cor-el.
I had Opera set as my default browser since this began happening. I changed my default browser back to Firefox mainly because having Firefox open one or two seconds every time I open Opera was/is such a nuisance.
I believe this problem began because I attempted to manually transfer the files from my old computer to the new one (via the backed up files in my external drive). I was unfamiliar with Windows 7 when I did this. Microsoft changed the file set up from what I had been used to in Windows XP. I used XP for six years before being exposed to Windows 7 (I never had Vista).
I'm almost sure this problem has something to do with where I placed the application data when I was trying to reestablish the program set up on the new computer.

How do I stop Firefox from opening its own homepage tab on top of my homepage?

Firefox keeps opening up its own website in my browser on top of my own home page even though I have reset the home page numerous times. Everytime I open firefox I have to reset my home page which works for a half-day or so and then ... we're back to the Firefox homepage. How do I keep Firefox from hijacking my browser?
P.S. I've tried all the stuff that's recommended -- resetting my homepage, etc ... and I'm just getting tired of having to do this. This is getting so irritating I'm going to stop using Firefox and start using another browser.

I am having a similar problem, I'm using "Show my home page" on start-up but firefox decides to always open to the last page visited regardless. I also generally close Firefox using the red X or with alt+f4. This problem is especially annoying when the last page 'visited' is an annoying pop-up ad that wasn't been caught by the pop-up blocker.

Check to make sure that mailto has not been set to open Firefox.
To do that open the Preferences dialog by selecting "Firefox > Preferences". In the Preferences dialog go to the Applications panel.

You can have infinite tabs opening if you have selected Firefox as the application to handle a file if you get an ''Open with'' download window. 
Firefox should not be selected as the application to handle a file and you have to remove the action that is associated with that file type. 
You can delete [http://kb.mozillazine.org/mimeTypes.rdf mimeTypes.rdf] in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder] to reset all actions or set the offending action in Tools > Options > Applications to 'Always Ask' 
See http://kb.mozillazine.org/File_types_and_download_actions ("File handling in Firefox 3 and SeaMonkey 2" and "Reset Download Actions")

How do I stop finder from opening a new window every time I download an image (drag and drop)?

Before I updated my computer I could drag and drop a new image from the internet to wherever I wanted on the desktop.

How do I stop it from doing both of these things?

How do I stop Firefox from opening unwanted sites or (inescapable) dialogs

My Firefox, as soon as I open a web page opens either (1) an overlying dialog typically flashing saying I am the 1000000th person or my computer is slow or buy this or (2) another unwanted site in another tab typically trying to sell something. Cases of type (2) are annoying but at least the tab can be deleted but cases of type (1) prevent me from using Firefox at all because the dialog does not have an exit button so I have to stop Firefox to get rid of it. This problem only happens with Firefox - IE never has these problems. I have scanned for malware using 3 different programs and I have tried deleting Firefox and re-installing it (keeping my profile) but the problem is still there. If I knew what the process was I could at least delete the process.
I love my Firefox - please help!

You can check for recently installed suspicious or unknown extensions.
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.
