Why does Firefox not pop up when I hit F12?

I'm using Windows Vista on a PC.
I usually have FF and IE open and minimized while working, and if I choose preview in IE it pops rigtht up ready for duty with the page loaded. But if I try the same with FF it loads the page but stays minimized.
Anyone else experience this? It's a pain in the @ss.

Hi Bopjo,
Please follow the instructions mention below.
1.) Open Adobe Dreamweaver CS5.
2.) Click on Edit menu.
3.) Click on Preferences.
4.) Select Preview in brower option.
5.) From the browser list select Firefox and select and check Primary browser option.
6.) Click on OK.
7.) Close Adobe Dreamweaver CS5.
8.) Open any html page and press F12 to check which web browser is coming up.

Put movies in itunes on one computer why does it not show up when i access itunes from other computers or ipad2?

put movies in itunes on one computer why does it not show up when i access itunes from other computers or ipad2?

i just purchased a file that had videos in it. i put them in the itunes library on my pc where i first downloaded them. i was able to transfer them to my other pc, a laptop, through my home network. i am now trying to get them on my mac pro desktop and my ipad2. my mac pro can see the other computers on my home network but i cannot get it to connect to them. i know the operating systems are different but was hoping i could transfer pictures and files from pc to mac this way. haven't been able to get it to work yet. the videos i am trying to get my mac to see came in a folder with both mac and pc versions. i thought if i got the videos i purchased into itunes that i would then be able to get them to my mac pro and my ipad2. i am new to mac/apple and have always been pc-centric so trying to marry it all has been difficult. i speak pc pretty well but am just learning apple. am i trying to do things that are not possible? i sure could use a knowledgable friendly soul to walk me through my issues of having pc and mac on the same network. i have been able to get all computers and ipad to print on my network. thanks.

Want new tab to open to home page and why does firefox not have a simple check box in the options because I can't keep going through a long procedure each time

I want new tab to open to home page and why does firefox not have a simple check box in the options because I can't keep going through the long tedious procedure each time I install firefox. It is something that should be in the options tab , and I want to know why it isn't. I am totally frustrated with firefox and getting ready to switch.

You can use the SearchReset extension to reset some preferences to the default values.
*https://addons.mozilla.org/firefox/addon/searchreset/
Note that the SearchReset extension only runs once and then uninstalls automatically, so it won't show on the "Firefox > Add-ons" page (about:addons).
If you do not keep changes after a restart or otherwise have problems with preferences, see:

Why does Firefox not work here in China anymore, since January of 2015?

I have used Firefox for years, as the fastest and most reliable browser for me, esp in China... not anymore! Last month (unknown to me) a hijacker called Vosteran took over my Firefox browser. I finally realized it and got it cleaned up using Malwarebytes anti-malware, and downloaded a new Firefox... now SAME problem exists, even with Vosteran removed!
Firefox will not allow me into ANY normal sites, saying they don't have the proper security code. This includes my Yahoo front page, email account, ESPN and other common sites that are certainly NOT dangerous. So, WHY does Firefox not work anymore? It is useless to me here in China the way it works now.

hello rickinchina, first please make sure that the '''date, time & timezone''' are set correctly on your system and that firefox is set to directly connect to the internet (that's the "'''no proxy'''" setting in the firefox ''menu ≡ > options > advanced > network > connection - settings...'').
if this doesn't solve the issue (or it is already set properly), a possible solution depends on different factors:
* what is the '''error code''' shown under ''technical details'' on the error page?
in case the error code equals ''sec_error_unknown_issuer'', please attempt to add an exception on the bottom of the error page (but don't do it for real) and inspect the certificate (see the screenshot attached for instructions):
* which '''issuer information''' does the certificate contain?
please report back with those two pieces of information. thank you!

Why does Firefox not launch after safe boot?

Folks:
I've been using ML for several months, no particular issues, yesterday as part of the monthly maintenance I did a safe boot, and after that firefox will not launch. Other 3rd party apps will launch, and of course Safari will . . . but, any thoughts as to why FF would go "limp"? When I click on it in the dock the icon bounces but then returns to the dock . . . I tried to launch it from the application folder and from the "previous application" launcher . . . . I tried it in a "guest" account that is never used . . . no difference. I did try to do something in the Terminal, but since I'm thinking that very soon I'm switching up to Mav, I haven't bothered to figure out how to add my regular user account to the sudoers list. But, I did try to launch FF in my admin account by the regular methods yesterday, no luck. Any ideas why this is happening . . . to me? Solutions are better, but, conspiracy theories also accepted . . . . =8 - 0
e.e.p.

Ran "Repair Permissions" several times . . . seems to be fixed.

Why does Firefox not allow me to go to Facebook, consistently says "untrusted connection"??

I have read through all of the responses to this exact questions posed by other users and nothing is working. What is the most frustrating is that this is not a constant issue. One minute I will be logged onto Facebook and when I try to visit a friends page or post something it will freeze, then the "untrusted connection" comes up. Or it will be working fine for a couple hours and I will log off of Facebook, when I come back a few hours later, or even a few minutes later I get the "untrusted connection" warning again. This has happened more now that Firefox has been updated and it is also happening to my roommate. She will be logged onto Facebook and I will try and get the warning, or vice versa. We are in the same room on separate computers. This problem does not occur on Google Chrome or Internet Explorer. This is an issue with Firefox, not my computers. We have four computers (2 Desktops, 2 Laptops) in our home, my boyfriend works in IT. We have done everything suggested by the people here and nothing works. I would understand if it was happening to one computer constantly and you tried to tell me it was my computer, but that is not the case. This happens with all four computers at different times. How can one person be logged on to Facebook and another isn't, then an hour later it will work on the latter computer and not the one it was working on previously. This is very frustrating. I love using Firefox over Internet Explorer and Google Chrome, I trust it more. But this is getting ridiculous. It has been happening for a long time, it just got worse with the update. Please help. It happens with Google and other popular sites as well.

This is what it says, every time for me
''''''''This Connection is Untrusted''''''''
You have asked Firefox to connect securely to www.facebook.com, but we can't confirm that your connection is secure.
Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.
What Should I Do?
If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.
''''''Technical Details''''''
www.facebook.com uses an invalid security certificate. The certificate is only valid for the following names: *.akamaihd.net, *.akamaihd-staging.net, a248.e.akamai.net (Error code: ssl_error_bad_cert_domain)

Why does Illustrator not remember filepaths when saving ??

Hi,
I'm finding it really frustrating that Illustrator 10 (on iMac G5 OS 10.3.9) does not remember filepaths when saving.
Perhaps I've overlooked a setting somewhere.
Does anyone know how I can rectify so Illustrator defaults to the last used filepath (as does almost every other program on earth) ??
I'd be very grateful for any help.
Thanks in advance.

Can anyone tell me why this is happening? Am I not saving this correctly?
Well, to what format are you saving? The native AI format should always retain layers. Other formats such as EPS or older PDF Levels may indeed enforce flattening. also make sure you are not confusing layers with groups/ objects. There's a crucial difference between the two.
And even more important, is there any way of restoring the different layers once this has happened?
Well, you can manually add new layers and drag&drop your objects and groups into the new layers in the layers panel, but if you save it again to the wrong file format, that is wasted effort, so for the life of it make sure you get that figured out first.

Why does Firefox freeze my computer when I click on an email address or link to a page that asks for contact information?

when i click on an email link, my computer freezes and firefox will open new tabs until i force quit the application. i downloaded the latest version of firefox for a mac, but it did not help. how do i correct this problem?

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.14) Gecko/20110218 Firefox/3.6.14
When I click on a mailto: link, Firefox freezes. This is new for me as of 3.6.14 (not sure if it existed in prior versions because I hadn't clicked a mailto: in a while).

Why does Firefox not scroll the page when selecting & the cursor reaches the bottom of the screen

When selecting text on a screen page, when the cursor reached the bottom edge of the screen Firefox (9.0.1) does not scroll. Other programs (including IE) do so, so it does not appear to be a local computer problem.
I cannot see a setting on the options page that enables/disables this so what is the solution?

Enable the Add-ons bar (Firefox > Options or View > Toolbars; Ctrl+/) or the Find bar (Ctrl+F) to make Firefox scroll the page while selecting text.

When I Log Out why does Firefox not save ALL my Inbox as before?

Why does Firefox not respond to any commands (it wouldn't even want to close) when I try to watch a stremline video from a webpage although all video-plugins are updated? The problem occured spontaneously, no changes were made to the system/settings.

Firefox does not crash but it 'freezes'. I cannot do anything with it then (it may be closed only from the task manager). Upon each subsequent opening the problem reappears (the fourth day in a row).

Haroon mentions two solutions. I used the easier one, which is to start the Apache webserver already in Mountain Lion and to enable the php already in Mountain Lion. It worked. I see the file correctly displayed with html, css, and php. I see the page by using Firefox. I enter an address in the address bar. For example, the address might be "localhost/example/example.php". I cannot see the page by using Firefox's "Open File ..." menu option or by dragging the file's icon onto Firefox's icon. I tried using your solution also but was unable to find the specific preference to modify. I found the page of preferences which may be modified but I could not find the one I need. I found a list of descriptions of the preferences at http://kb.mozillazine.org/Firefox_:_FAQs_:_About:config_Entries
but I could not find the specific preference which I need.
By the way, to enable loading the php module, one uncomments a line of code by deleting the initial "#" character, and one does that by pressing control key and "P" key while the cursor is over the "#" character.
Also by the way, when I use Firefox or Safari to look at the Apache web directory in which my files are, the files are listed case sensitively. For example, the files are listed: Ace, Zygote, bar. This is because lower case follows upper case. THis annoys me. I prefer case insensitive listing. When I llok directly athe directory without using a browser, the files are listed case insensitively. For example, they are listed: Ace, bar, Zygote. I guess taht Apache is doing this.

Why does firefox update itself even when i tell it not to? Everytime it updates itself it messes up and crashes, make it stop. I like firefox but if I keep having to unistall and reinstall it ever month to every other month I am going to be done with it

Fire Fox updates itself even after I tell it not to. The new version it updates to crashes, adobe flash player doesn't work on it and it takes forever to load when it does work. I have used fire fox for years now but if this keeps up I will find something else to use.
== This happened ==
A few times a week
== When you came out with fire fox 6.6 or whatever

I also have this problem of Firefox updating by itself even when I turn off auto-update.
For whatever reason, there are situations where you do not want to update or download a large file, because you're working offline, have a slow connection, or have a very low download allowance etc. Usually the update doesn't work and cause Firefox to crash. After that it cannot be started again. This is with Firefox Portable but I think I've had this problem the normal Firefox. With the portable version I can just back up a single folder but it is still time wasting and annoying.
I've noticed that when I start Firefox with auto-update turned off, it changes the options to auto-update, it also does this periodically. So every time I start Firefox I have to turn off auto-update, and I have to do this from to time because Firefox will by itself turn back on the auto-update.
