You can check if you can start Firefox in [[Safe Mode|Safe Mode]] by holding down the Shift/Options key.
*https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
It is possible that your security software (firewall, anti-virus) 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 and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to install for Firefox and the plugin-container process and the updater process.

Why is Mozilla Firefox so slow? It drives me nuts.

Why is Mozilla Firefox sooooo slow? It's driving me nuts.
And why can’t it ever connect me to my email on the first try?
And why does Firefox need to be rebooted so often?
It's all very frustrating.
Please respond.
Thanks

I took my computer in for cleanup yesterday and the tech told me not to resort to using safe mode, he uses Chrome and said all the features in these files need to stay there. He says he thinks Firefox needs to do some tweeking on their end because he's had so many people complaining of how slow it is. The newer the version, the slower it gets. Maybe if they quit adding so much junk you don't need, like the earlier versions, but can't download them anymore. So I'm doing like my technician and jakfak are doing, NOT using Firefox until they fix it. Chrome is my baby now.

Why does Mozilla Firefox use Google as their web search if Google stores everything we search?

Why does Mozilla Firefox use Google as their search engine if Google stores everything you search and track what you do online? I've got nothing against Firefox, I'm just wondering why.

I just figured they wouldn't have since they don't track what people do. I figured they were against that.

From what I understand RAW photos are supposed to open in raw in photoshop CC. I don't understand why my RAW photos don't open in RAW in photoshop CC or Lightroom 5

From what I understand RAW photos are supposed to open in raw in photoshop CC. I don't understand why my RAW photos don't open in RAW in photoshop CC or Lightroom 5

Has the behavior changed compared to how it used to open ? If so, do you refer to the Camera RAW window similar to this: http://screenshots.en.sftcdn.net/en/scrn/78000/78026/adobe-camera-raw-22.jpg
What is the file extension of your photos ?
In Lightroom, there is no special way of opening a RAW file vs. JPEG. They all open the same. What is the Lightroom behavior ? Can you post a screenshot ?

Why is mozilla firefox not opening after updating?

Why does Mozilla Firefox open to a previous session?

Whenever I launch Mozilla Firefox, a session from a little more than a week ago opens up. Usually it opens up to my homepage. Now, it opens up with 8 tabs. They are: my Yahoo mail, my Gmail, 4 other Google sites, and an Amazon site.
How can I put a stop to this?
Thank you to any and everyone with a suggestion.

It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
Delete the sessionstore.js [2] file and possible sessionstore-##.js [3] files with a number and sessionstore.bak in the Firefox Profile Folder.
* Help > Troubleshooting Information > Profile Directory: Open Containing Folder
* http://kb.mozillazine.org/Profile_folder_-_Firefox
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).

How can I make the initial "Meet Mozilla Firefox" window stop opening?

I update to Firefox 8 today and now every time I go into Firefox I keep getting the "Meet Mozilla Firefox" window. How can I make that window not open again?

It sounds like maybe your home page was accidentally set to include multiple pages, including the add-on manager. Try opening the Firefox options window and pasting the address of just your desired page in the "Home Page" field.
For more details, see: '''[[How to set the home page]]'''

How do I stop the "Meet Mozilla Firefox" page from opening in a second tab when I launch my browser?

Since the latest update, every time I open my Firefox browser, it opens two tabs. The first tab is a "Meet Mozilla Firefox" tab and the second is my Yahoo! homepage. How do I stop the meet mozilla tab from opening and only have my yahoo homepage open?

Refer to this help article on [https://support.mozilla.com/en-US/kb/How%20to%20set%20the%20home%20page?s=home+page&r=0&as=s How to Setup the Home Page].
If this still doesn't work, do the following:
* in the address bar type "'''about:config'''";
* click the button "I'll be careful I promise";
* in the bar type "'''browser.startup.page'''";
* right-click on it, and change the value to "'''0'''";
* re-start your browser.
Hope this helps.
Edit: just changed formatting.

How do I stop the "Getting Started with Mozilla Firefox" tab from opening every time I open FF?

Every time I open FF, the "Getting Started with Mozilla Firefox" tab opens. I have checked and it's not in my homepage list.
If I open any additional windows, it doesn't open.
But, once I close all of them and reopen it again, the tab opens.
I've had a similar problem with a couple addons (ietab) doing the same thing.

about:config is typed into the address bar as if you were going to a web page.
It will popup a message warning you that you are messing with important stuff.
Just agree.

Why does Mozilla Firefox Yahoo permit Astromenda to attack PC's

Every time I download Firefox, I get this viral adware malware on my PC. And I spend hours getting rid of it. Why doesn't someone stop it?

Why are you using Mozilla Firefox Yahoo, rather than the official version of Firefox which is available directly from Mozilla?

Mozilla-firefox can't open

I've upgraded mozilla-firefox to 0.9-1 and I can't open it now. Am I the only one?

I upgraded both firefox and thunderbird and had no problems. firefox asked me first time I opened it, if I wanted to copy over my .8 configuration. I said ok and everything still worked great, even all the plugins (mplayer, flash, java).

Why does mozilla firefox randomly launch by its self in windows 7

When the PC is idle Mozilla Firefox suddenly opens with me clicking on anything. The operating system is Windows 7

Are web pages opened when this happens?
Does this also happen when you set another browser as the default browser or is the other browser that is set as default browser opened instead?
Do a malware check with several malware scanning programs on the Windows computer.
Please scan with all programs because each program detects different malware.
All these programs have free versions.
Make sure that you update each program to get the latest version of their databases before doing a scan.

I don't know why but suddenly Firefox won't open anymore. I discovered that it will open again as long as MSIE is running. Why and how can I fix this?

I've been using Firefox no problem for a long time but suddenly it stopped running today. I click on the icon and nothing happens. I updated to the most recent (just in case) and it still isn't loading up. Out of frustration I opened MSIE to search for this problem and I noticed that Firefox was working again. But, when I closed out of MSIE I couldn't get Firefox to work.

Not sure what you mean then. Is QuickTime still open and playing the video? If so, do you mean you can't even get back to QT to shut it down?
Check the Dock for the QT logo. Click it to bring that app to the foreground. The menu bar then should say QuickTIme Player next to the Apple logo. Close the app and the video will shut down with it.
