When I start Firefox I get an ad to fix my PC

Every time I start Firefox, a pop up ad about fixing my PC appears. I want to get rid of it.

hello ram085, there's a user.js file present in your profile folder, which is often used by adware to override your custom preferences.
in order to fix that go to ''firefox > help > troubleshooting information > profile folder'' - "show folder", then a new window will open up. in this window look out for a file named '''user.js''', in case it is present , delete or rename this file and restart firefox afterwards.
 [[How to fix preferences that won't save]]
finally you can install the search reset addon which will revert the most common changes by adware programs in firefox: https://addons.mozilla.org/firefox/addon/searchreset/

Lyall,
I have seen this before, a long time ago (several years), and I cannot
remember how/if we resolved it.
If this is an impotant issue to you, I suggest that you open a case with
BEA support.

Peter.

This is a rather important issue, I have seen another post with a similar problem.
While not being a show-stopper it certainly raises concerns.
The application works ok until the application exits (in both development and
executable form)
Apparently this did not happen with Tux 7.1
It does with 8, I do not have 7.1 so I have no workaround.

It is possible that your anti-virus software is corrupting the downloaded files or otherwise interfering with downloading files by Firefox.
Try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.

My toolbar is missing and there is a button where it used to be that says "Please re-install the Toolbar" but when I click on it nothing happens? Also when I start Firefox I get a script running error how do I solve these issues?

My toolbar is missing and there is a button at the top left that asks me to "Please re-install the Toolbar" but when I click on it nothing happens???
Then when I start Mozilla I get a long delay before it launches and a script running error "A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.
Script: chrome://tavgp/content/libs/include.js:595"
How do I solve these issues???

No idea - and you provide no clues
what version of iPHoto do you have? Of the OS? is the iPhoto icon you are speaking of in the Dock?
re-read your post and try to provide information using standard Mac terms since we can not see you or your computer and only have your worrds to let us try to help you
Somehow my "IPhoto" icon now says "Preview". When I click on "Preview" nothing opens up except the bar says Preview. When I click on the Preview on the bar, a box opens up with different items, except when I click on any of them, there is nothing there. The only thing that work is the "quit preview". However, it is still there where my IPhoto icon should be. I can't get into my IPhoto. How do I get rid of this "Preview" and how did it end up taking over the IPhoto icon???
If you go to your Applications folder and double click on iPhoto what happen?

Just updated to v5.0 and now when I start Firefox I get a pop-up that says checking compatability of add ons and the the Welcome to Firefox page and my home page appears. Can't get rid of the pop up or welcome page.

Above question covers it. I've tried reinstalling Firefox, clearing cache, history, etc. but still happens. I've created app tabs and when I restart Firefox, they are gone. Running Windows XP.

It is probably because you are not properly closing Firefox. Restarting your system would make sure that Firefox had terminated, but you do not have to do that.
To properly close Firefox on Windows systems, use
:File > Exit or "Firefox:" button > Exit
When you get the message "Firefox is already running" it is too late, and you must force termination of Firefox through the Windows Task Manager before restarting Firefox. Windows 7 has a keyboard shortcut to save you a step "Ctrl+Shift+Esc" then on "Processes" tab, select "firefox.exe" and use the "End Process" button. More thorough would be to right-click on the "firefox.exec" and choose "End Process Tree".
You would find firefox.exe in a Mozilla folder in your program files, but y0u would not want to delete it there, you would need to use the Control Panel which you have already identified and do it from there -- but generally you would not need to do that, and there is nothing in what you have posted to indicate that you should. But if you did do that, then don't let the install start Firefox for you as you would want to use you existing desktop icon or method of starting Firefox, and should decline having Firefox install start Firefox for you. When the install starts then invoke Firefox in your normal manner. This should eliminate problems of creating a new profile rather than using your old profile.

When I start Firefox, I get this alert message "[JavaScript Application] XML tag name mismatch (expected META)". What is this message?

My firefox updated today automatically, and then when it started up, it displayed this alert message:
"[JavaScript Application] XML tag name mismatch (expected META)"
I can press OK and my browser then works just fine and I can go to websites and what-not. I have not run across any problems or anything. I am just wondering what this alert message means and if I should fix it?
I tried closing the browser and pulling it back up, and the same message was displayed. Also, if I open a new window the same message is displayed. But it is only displayed right when I open the browser, and does not show up anytime while using the browser.

If you click the Home button from another page, does the error repeat? If so, what is your home page?
When Firefox starts, it fires up a lot of add-ons. A standard diagnostic for add-on issues is to try Firefox's Safe Mode.
First, I recommend backing up your Firefox settings in case something goes wrong. See [[Backing up your information]]. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)
Next, restart Firefox in Firefox's Safe Mode ([[Safe Mode]]) using
Help > Restart with Add-ons Disabled
In the Safe Mode dialog, do not check any boxes, just click "Continue in Safe Mode."
Do you still get the message? If not, one of your add-ons might not be fully compatible with Firefox 14 or might need an update.

When I start firefox I get a jarva script error component classes (cid) is unidentified

the above message appears in a pop-up box and when I click the OK button firefox opens fine

This issue can be caused by an extension that isn't working properly. 
Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes). 
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. 
You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions. 
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

When I start Firefox I get an error message

When I go to start Firefox I double-click the icon and it says 'Windows cannot find X:/lib/deploy/jqs/ff/../../../../bin/jqsnotify.exe' with X being the letter of the hard drive.
Also as a quick side note: whenever I try to use a web page that uses java (ej: RuneScape) Firefox will automatically crash without warning.
I would be grateful to receive an answer to both of these questions.
Thanks,
Daniel
P.S. I noticed that I am asked to 'Enter the text from the Tools > Addons > Extensions panel' and when I click on 'Add-ons' Firefox will crash.
== This happened ==
Every time Firefox opened
== I cant remember

Hi Daniel,
Sounds like you have a broken install of Java. Try uninstalling all versions of Java from Control Panel -> Add / Remove Programs, and then installing Java again.
Try disabling the Java Quick Starter in Tools -> Add-ons -> Extensions / Plug-ins. (If still crashing, try doing it in [[Safe Mode]])
Do you see a Mozilla Crash Reporter dialog when you crash?
For us to see your crash report that you have submitted:
#Go to '''about:crashes''' in the Location Bar.
#Copy the blue links (beginning with bp-) and paste them here.
Finally, for further info, see [[Using the Java plugin with Firefox]].

When I start Firefox I get this error: [JavaScript Application] Exc in ev handl: TypeError: this.oRoot.enable is not a function. How can I fix this?

This problem started suddenly, and I need to close the error message window so Firefox Browser can start.
I have the latest JavaScript version.

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).

Can't restore session always shows up when I start firefox.... how to fix this?

Every time I open firefox I get the "Well, this is embarrassing...." message. I have read everything on the support site that seems to pertain and have tried adjusting settings, but to no avail. The CAN'T RESTORE still pops up. This is not happening as the result of a crash. I have FIREFOX WILL: set to open home page.

hello, this is currently a problem in firefox when you first close all open firefox windows and then close the application afterwards - the bug should be addressed in a later version of firefox.
as a workaround in the meanwhile you could close firefox (through firefox > quit) while the browser window is still running or try this: enter about:config into the firefox location 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'''.

When I start Firefox, I get msg that it is in "offline mode" and need to "try again" to get online. Started after latest update 10.0.1

When I click onto the Mozilla Firefox icon and open the browser up, it doesn't automatically connect to the online server. Instead, a message appears that it is in offline mode. If I want to go online, I am instructed to click a "Retry" button. This then initiates the online mode.
It doesn't happen all the time but most often first thing in the morning and/or if Firefox has not been opened for a few hours.
Is there something I need to change in the Firefox Preferences under Network/Connection/ Settings?

None of these "fixes" seem apply to Mac OSX10.6.8 . Since I installed the latest update for Firefox I, too, am getting this offline mode and retry message every time I open the browser.
I am not a programmer, so will appreciate a fix I can understand and safely execute to make this terribly annoying message go away.
Work Offline is NOT checked but does appear under the file menu.

When I start Firefox I get a menu box asking me to agree to let Firefox make changes to my computer. I click yes and the program opens and goes to my homepage. See Details below.

When I attempt to open Firefox from my desktop icon a menu box appears and backscreen grays out and I can't access anything else except this menu box. top of menu box says User Account Control. Next line says: Do you want to allow Firefox to make changes to this computer? I can click Yes (Firefox opens) No (menu box closes Firefox doesn't open) A link I can click says "change when these notifications appear" When I click it the menu box closes, Firefox doesn't open & link does not take me to where I can change my user account controls. Annoying, I just want Firefox to open directly to my home page like it did in prior versions.

Do a clean reinstall.
* Download a fresh Firefox copy and save the file to the desktop.
* Firefox 7.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Uninstall your current Firefox version.
* Do not remove personal data when you uninstall the current version or you lose your bookmarks and other data in the profile folder.
* Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

When I start Firefox, I get a blank white screen.

Only rebooting helps. I will reboot, it will be okay for a while, then the problem will come back. I have the same problem with SeaMonkey.

A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process.

When I start Firefox, I get an error message instead of my home page: Server not found Firefox ca

The error message is: Server not found
Firefox can't find the server at co108w.col108.mail.live.com.
If I then hit "Home" it goes to the home page. Changing the home page hasn't helped. Resetting Firefox hasn't helped. This just started today. Restarting the computer didn't help.
I'm using Firefox 18.0.2 and Windows 7.
Thanks.

When i Start Firefox I get the following error message: Could not initiate the application's secutity component. Then I am unable to open any websites.

It says the mostly likely cause is problems with files in your application's profile directory.

Hi,
Please try this: '''Help''' ('''Alt''' + '''H''') > '''Troubleshooting Information''', click '''Open Containing Folder'''. This opens your [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder & Files]. Exit Firefox and rename '''cert8.db''', '''secmod.db''' and '''key3.db''' in the profile folder. You can delete them later.
