Why does firefox keep changing colors?

Suddenly the Firefox background color keeps changing (blue, tan, gray) I would like to keep it one constant color. How/ why did this happen today when I changed nothing, and how do I fix this?

Are you using Firefox theme and choose Random theme option?
'''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that turns off some settings and disables most add-ons (extensions and themes).
''(If you're using an added theme, switch to the Default theme.)''
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu by clicking on the '''Restart with Add-ons Disabled...''' menu item: 
[[Image:FirefoxSafeMode|width=520]] 
If Firefox is not running, you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac: Hold the '''option''' key while starting Firefox.
* On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
''Once you get the pop-up, just select "'Start in Safe Mode"''
[[Image:Safe Mode Fx 15 - Win]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
When you figure out what's causing your issues, please let us know. It might help others with the same problem.
Thank you.

Why does firefox keep changing things up with new versions?

It really bothers me that Firefox keeps changing things, namely the user interface with new versions. They move buttons around like the back / forward, and refresh button. If I don't have the latest version I get prompted to download it each time I open my web browser. Now with this latest update I got a good inch and a half at the top of my screen that should be gray but is transparent and shows my desktop background. Also, I like to right click and 'open link in new' tab a lot, I thought it used to be 'open link in new window' first than 'open link in new tab' second. They switched them around now I'm opening new windows instead of tabs from clicking the second option by habit. Its not that big of a deal but why keep changing it up when I'm comfortable with what I know.

You can use Themes or Personas to change the display of Firefox browser.
* https://addons.mozilla.org/en-US/firefox/themes/
* https://addons.mozilla.org/en-US/firefox/personas/
You can Middle-click a link using Mouse or use '''CTRL + Left-click''' shortkeys to open a link in a New Tab. See these articles:
* [[Mouse shortcuts]]
* [[Keyboard shortcuts]]
Check and tell if its working.
Not related to your problem but some of your Firefox Plugins are out-dated, so you need to Update them.
-> Update All your Firefox Plugins by visiting the following link:

Why does FireFox keep changing the window when clicking on another program??

I upgraded to FF 8 recently. When I start it and go to, say, Gmail (in window A) then open another browser window (window B) to go to, say, Facebook, if I click on another program such as Live Messenger or even a reduced window of another program the window in FF always changes. I.E., I look at window A while B is open. I click on the message box from Live and the window changes to B. I click on A to get back to that window then click on the Live box again and B pops back up. I can't get it to stay on A no matter how many times I try.

Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

Why does Firefox keep hanging, crashing, sulking, dying when internet connection behaves?

Why does Firefox keep hanging, crashing, sulking, dying when internet connection behaves? Once it renders the page it should forget about the page. Why does it behave when some link is clicked when there is no internet? It should just say internet not available or some crap. Why die, sulk, crash?? I don't get it! 3 series was much much much better!

I should add, I've re-downloaded Firefox, but that doesn't look like it has helped any. Still get seemingly inexplicable crashes.

You need Flash Player or DivX Player. Both of these programs are used everywhere online; their size is small and will not harm your computer. You should download them from here:

Why does Firefox keep opening 3 random tabs while browsing different websites?

Just to clarify: They are never spam websites. They may be 3 of the same website, but it is always random. I only browse safe websites. This usually happens while Stumbling (StumbleUpon).
For example:
StumbleUpon brought me to this website:
[[http://www.thecreatorsproject.com/blog/5000-fiber-optic-flowers-invade-museum-grounds-in-ifield-of-lighti]]
Then it also opened three of this webpage:
[[https://en.wikipedia.org/wiki/First_Earth_Battalion]]
They have nothing to do with each other. Why does this keep happening? I searched with Anti-Malwarebytes, SuperAntiSpyware and Microsoft Security Essentials. No viruses.
I have Windows Vista Home Basics 32-bit. And is running Firefox 8.0. (This problem existed in 7.0 and previous as well.

I've already done this, and it says nothing is wrong with my system.

From IMessage to normal text. Why does it keep changing?

I am messaging and texting a friend who also has an iPhone. Now All it will come up with the green text but in some rare cases it will randomly turn to iMessage.
Why does it randomly change without me doing anything?

Why does firefox keep crashing? I ran a scan and there was no spyware or malware. I uninstalled and reinstalled firefox. It doesn't happen in safe mode.

For some unknown reason firefox keeps crashing on my laptop computer. I mostly just use the internet for surfing and for emailing. It is very frustrating when I am trying to write an email and firefox crashes. I have unistalled and reinstalled firefox. I ran a McAfee scan on the computer and it has no problems with spyware or malware. It doesn't crash in safemode either. I am in safe mode now otherwise it would have crashed multiple times while getting to this page and typing this message.

If Firefox crashes frequently but stops crashing when you are in Safe Mode that is a pretty sure sign that there is something wrong with your individual setup of Firefox on your Windows 7 machine.
(The 99 others claiming to have the same problem this week probably have their own distinct and separate problems - if you are one of those 99 it may make sense to start your own questions about your problems, if you do not see suitable answers).
Many malware problems would continue even in Firefox's [[safe mode]], so the good news is that malware may not be your problem.
Note that safe mode does not disable plugins, you may wish to consider testing with your plugins disabled, just in case they are interacting with something. To temporarily disable plugins use
* '''Firefox button -> Add-ons -> |Plugins|'''
You do not list the Firefox extensions that are in use, maybe one of them is a problem. I suggest you try Firefox with half of them disabled, if that solves the problem, the troublesome add-on may be in the other half, disable them all and then try with half of the other half enabled. (If you have more than a handful of add-ons it is faster testing like that than enabling or disabling one at a time)
One very important question is how do you know Firefox is crashing ? will you please explain exactly what happens, and what if any error messages you are seeing. (If firefox freezes/hangs that may be different from Firefox or the OS crashing, and require different solutions).
On a general note the following articles may help with troubleshooting:
* [[basic troubleshooting]]
* [[troubleshooting extensions and themes]]
* [[http://kb.mozillazine.org/Standard_diagnostic_%28Firefox%29]]
and if the problem is a true crash

Why does Firefox 31 change all PDF icons and opening in browser, require a fix using REGEDIT to fix for ALL USERS on a computer?

The solution to use REGEDIT in the question linked below almost fixed my trouble with PDF files on over 30 computers, with several users on each computer:
https://support.mozilla.org/en-US/questions/1013642
But I needed to fix it for ALL users on a computer, without logging onto each account, on each computer. My fix was to logon as administrator and change the following system-global key instead:
HKEY_LOCAL_MACHINE\Software\Classes\.pdf
Name: Default
Type: Reg_SZ
Data: FirefoxHtm
Changed the data from FirefoxHtm to AcroExch.Document.11
I use Adobe Reader XI on Win7 Pro, 64-bit machines.
The problem started when I ran a downloaded file to install the new version of Firefox on the computers.
Why would Firefox require me to use REGEDIT in this manner to fix the problem?

This only happens when you set Firefox as the default browser and Firefox thinks that there is currently no application the handles PDF files.

Why does Firefox keep defaulting to Yahoo search instead of Google regardless of correcting the preference?

Not much more to say really, started a week ago so i changed my home page pref's etc and it just goes back to yahoo.
deleted firefox and reinstalled version 17 same problem?

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).

Why does iCal keep changing to colour of one of my calendars?

For some reason, every time I open my iCal the colour of my "work" calendar is changed from Green to pink(one of the create your own colours). I keep changing it back to green and it keeps going back to pink. I am incredibly frustrated.
Any suggestions?

Okay,
Kind of got a fix for this or at least it seems to have worked for me. *Knock on Wood*. It will take some time and patience.
I right clicked on my "Work" calendar and exported it to the desktop. Then imported it as a new calendar under a different name "0 - Work". (It may import it as "Work 2")
Now you have your original "Work" calendar, in the annoying pink colour, and a new "0 - Work" calendar.
Change the colour of this new calendar to whatever you like. Delete the original "Work" calendar and then wait about 10 minutes. This seems to allow the iCloud and whatever else to finish its "Updating".
Then rename "0 - Work" to just "Work". Again wait about 10 minutes. It's best not to sit there and watch as the updating processes will sometimes change it back to pink or bring back the original "Work" calendar before finally settling on your new changes.
In the end, or at least for me, things are back to normal. I have left it open for about a half hour, turned it on and off and no pink has reemerged.
Good luck!

Why does Firefox keep crashing with Mavericks?

I don't want any answers on this, but I would strongly suggest that people should not download Mavericks. I did so today, March 22, and since then Firefox keeps crashing or going into the spinning wheel mode. Once it actually shut down my domputer. Clearly Apple updates are becoming as worthless as windows updates.

I haven't had any issues with Firefox and Mavericks. The only issues I've had have been minor.
I suggest you test in a new User. This will quickly tell you if the problem is system wide or if it's your User's folder that contains the problem.
CREATE A NEW USER
Go to System Preferences --> Create a New User in Accounts. Switch to the New User by logging out/in or use Fast User Switching
Do you still see the issue?
If yes, then the problem is with your base files.
If no, then the problem is in your User's folder.
Download EtreCheck. It will display the important details of your system configuration and highlight old files you still might have around that will affect Mavericks. If you need help with the results, you can copy the results to the Clipboard. and paste on the fourm.

I get notifications of changes for radiowmpcoregecko7.dll. It is indicated that it is from Firefox. What is this file for and why does it keep changing.

About once a week to two weeks I receive notification through my anti-virus that this file has been changed. It appears to be part of Firefox. What is it and what does it do?
Thank you.

Why does firefox keep making it my default browser when I keep changing it to IE it changes back to firefox

So every time I go to firefox it makes it my default broser but I dont want it to i changed it to IE but it changes back to firefox again. And I dont want firefox as default.
== This happened ==
Every time Firefox opened
== about a week or so ago ==
== User Agent ==

Hello Mandy.
I can't think of a scenario where Firefox would make itself the default browser against the user's consent. Still, go into Tools > Options > Advanced > General > System defaults and untick that small box at the bottom of the window that talks about Firefox asking you each time it starts.
Hopefully that will fix the issue.

Why does Firefox keep opening new Windows rather than a new Tab in the current window?

I have " Open a new Tab in the current Window" select in Preferences.
Why then does this version (Version 4) keep opening new Windows, rather than new Tabs in the current Window.
This feature worked fine in 3.6.1.3, but in Version 4, it is a frigging pain in the rigging!
C'mon, Mozilla - time for an URGENT update ...

That issue can be caused by an extension that isn't working properly.
