Why is my FireFox browser application either taking multiple attempts to open or not opening at all?

When I click the FireFox icon, the application will not readily open. I usually have to go into Task Manager and delete the process and I must do this several times. At times the application does not open at all and I just have to wait after shutting the computer off. I removed FireFox and re-downloaded the most recent version. It did not help. I clean the cache/defragment and have malware detection software. I check updates. Please advise.

Photoshop Elements 1.0.1 seems like very old software 2001 I believe. Try asking in the Elements maybe someone there will be able to answer your question. Photoshop Elements

My firefox browser no longer closes, minimizes, or restore up or down the window, all of them are grayed out

Whenever I have Firefox browser window open, and then select to open a private browsing window, the open Firefox browser red X close button grays out and does not close, minimize, or restore up or down. This happens to both the regular Firefox browser window and the private browsing window.
Sometimes, this occurs when only the regular Firefox browser is open and not any private browsing windows.

Hi CoolDave,
Thank you for posting your question. I understand that when you have both a private window open and a regular window open, sometimes the window will not minimize or restore, and that the buttons at the top of the screen are greyed out.
In order to better investigate this issue, can you please try the following:
* Does this happen in Safe Mode? '''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.''
*Is this the only program this is happening to? And if you use the short cuts to minimize and maximize the windows, does the window respond to these? [https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly#w_windows-tabs]
* These were some workarounds for windows 7 [http://annoyances-resolved.blogspot.com/2009/12/firefox-unresponsive-workaround-7-for.html]
We look forward to your reply!

Each time I open my Firefox browser, the tab from the last time opens. I have the browser set to open on my home page, not to the tab from the last time. I keep trying to save the setting for the browser to open on my home page but it doesn't.

Try to create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
*https://support.mozilla.org/kb/Basic+Troubleshooting#w_8-make-a-new-profile
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If the new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

Why is my Firefox browser slow all of a sudden?

All of a sudden, my Firefox browser is extremely slow. I did not change anything nor did I download any software.
It takes me some time to go to web pages and such. What can i do?

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.
*https://support.mozilla.org/kb/Safe+Mode
*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 internet for Firefox and the plugin-container process and the updater process.

Why does the first Firefox browser takes more than ten seconds to open?

Once my laptop is logged into, Firefox's initial browser takes more than 10 seconds to open. The subsequent windows take less than two seconds. Much more complex programmes like photoshop open in next to no time. Is Firefox a 'heavy' programme to start?
== This happened ==
Every time Firefox opened
== I shifted to Firefox Windows IE two weeks ago. Eversince.

Somedays firefox crashes 10+ times within minutes, other day it does not crash at all. It will crash when opening, in email, or just on any web site. No rime or reason! Why?

I am not technical at all. I just want to know why somedays my system crashes over and over again, and other days all is well. Each time it crashes I get a "crash report" option, and I always send in said report, but I do not think anyone is checking those!
This has become a real issue and I am very tired of it.

Firefox Browser Outlook SkyDrive playing m4v file with sound but not video

Firefox Browser Outlook SkyDrive playing the m4v file. I have sound but not the video. Sound and video play ok with IE10.

I'm amazed that each time these type of problems arise we get the same advice time-and-again to go through this exceedingly manual process of due-diligence checks-and-balances to figure out what it is that we have as ad-ons that supposedly now clash with changes that FF have made to the browser.
Everything is provided to FF with the post yet we are expected to check in SafeMode everything that was passed compatible when FF was updated.
It all comes across a bit lazy I have to say - no disrespect intended to some at FF who will no doubt come back to "slap my wrist", telling me not to be "rude", "refrain from using so many ????? together", telling me yet again "the problem is with your plugins" - especially when history shows us that such checks I'm asked to make "after the event" often do not resolve the problem, more so given that the last FF Update validated all of them, switch off those that weren't and checks on them since show that all are the latest up-to-date without any changes being made to them by me . Then the problem gets resolved by someone else on the forum basically beta testing what should have been checked-out thoroughly by FF in the first place.
Sorry to go on a bit of a rant-and-rage B-U-T we are not getting these repeated problems withe other browsers which we are getting more and more frequently with FF.
Never mind. I'll go through this rigmarole of checks yet AGAIN, no doubt then having to put up with the same sequence of threads from the likes of Morbus re the Plugin-container fiasco "Nothing to do with this [whatever we put forward it might be]. Try flash [or this or that or something else]. Uninstall it and reinstall it. Make sure it's up to date too.", like we're a bunch of morans who don't have the dummy sense to check these things out thoroughly before we go asking for help on the FF Forum.
"Let's blame the add-ons that have nothing to do with FF" Nowt has changed on that front since 08/2010.
Still, what can we really expect from a free browser? A browser that works?????
I hate IE --- but at least it isn't failling over with hardware acceleration issues every few updates!!!!!

Ff6 beta is taking a very long time or not loading at all sites from links or bookmarksmarks

firefox 6 beta auto updated now when I click on links or book marks site either take a very long time to load or do not load at all.When I tried to log into my back acct. it never loaded.

No clue why the final processes have suddenly started to take so long. Two things I'd try: a) capture from an older tape to see if some problem with the new tape is at fault. And b) check the health of your RAM and the hard drive.
The red frame sounds a bit like a glitch we used to have in OnLocation (actually in its predecessor HDV Rack) which was caused by a partial GOP. But that was a product of HDV Rack recording from the live video stream. It turned out that HDV cameras intentionally interrupt the data stream for an instant upon starting to record--specifically to avoid recording a partial GOP to tape. So my gut says that the tape has partial GOPs at the points where you stopped/started recording.

Why does my firefox browser closes often without warning or any pattern.

I'm not sure what details I can provide. This has been happening for a little while but seems to be increasing in frequency. I have not made any recent changes to my system which might have created the issue.
Basically, the browser simply shuts down and disappears. There is no patter to what I am doing, or to specific pages that are opened. It happens on pages that I have used often and, in some cases, even pages I created myself.
When I reopen Firefox, it gives me the option to reload the page(s) that were closed or to start over. I have tried both options and had the results either way, which is basically a recontinuation of the problem, especially if I try to return to the page I was on.
My version of Firefox is completely up to date.

If you made changes to your system, then you may have corrupted Firefox files.
What I suggest you do in these circumstances is to reinstall Firefox. This is perfectly safe and you won't lose any data. To proceed, do the following. 
#Use Internet Explorer to download Firefox 5.0.1 from this link: [http://www.mozilla.com/en-US/firefox/fx/?ref=logo Download Firefox 5.0.1] and choose "'''Save'''" when you see the prompt. Then save it to your desktop. ''Do not choose "Run"''. 
#Then go to Add/Remove Programs in Control Panel, scroll down to "'''Mozilla Firefox'''" and remove it, choosing to keep your bookmarks, customizations etc., (''don't checkmark the box''). 
#Then reboot and delete the folder called "'''Mozilla Firefox'''" at this location: ''C:\Program Files\Mozilla Firefox'' 
#Finally run the installation file you downloaded to the desktop earlier. 
Your bookmarks, customizations etc., are maintained in a different location and will become available to you again once you complete the installation. 
If this suggestion fixes the problem for you, please click the '''Solved it''' button ''next to this post'' after you log in into the forum. This will help others searching for a solution to the same subject.
Thanks.

Why is the Firefox browser not recognizing ANY Flash player add-on?

I recently updgraded to Flash 17.0 and find that the browser often doesn't recognize my Flash player add-on. The crazy thing is that it's available in my list of add-ons, but whenever I enable and disable it, Firefox never recognizes that it's present when I go to sites that use the add-on.
I recently uninstalled the latest version of Flash and went back to an older version (10.3 I believe), and that still didn't change anything. I even did the little trick where you go into your "help", "Troubleshooting information" and "show folder" to delete "pluginreg" DAT, but it seems you have to do this EVERY new session on Firefox.
This is ridiculous. Flash is so often used on websites that I can't believe Firefox would upgrade its browser and not have something as essential as its compatibility with Flash all ironed out prior to the upgrade. I've read through the other answers to similar questions on here, and NONE of them offer any kind of permanent fixes. It'll all crap that you have to do manually every time you start a session on the browser.

Nope. I tried both things, and neither worked. I went through the work of downloading and installing both ActiveX version and the plug-in version. I then delete the plugin.dat after I closed out of my last season of Firefox.
It seems to work immediately after I do this, but if I disable Flash, at all, as I often do during most of my browsing and then enable it before I go to youtube, youtube still doesn't recognize the plugin and tells me I need to go download it.
It looks like I'm going to have to go and reset my plug-ins, but I REALLY don't want to do this. This is ''insane''.

Why does the firefox browser show information that is not normal
