FireFox is getting slower and slower

I have been using fireFox for several years. i have a new Dell running Win 7 64bit. My ISP is Hughesnet satillite w/ downoad at 1Mbps. I have the latest update.
The last few days pages have been loading slower and slower. As a matter of fact I'm forced to use IE9 to contact you.
IE9 and Chrome load pages at the expected speed

Hello,
Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
More information about reinstalling Firefox can be found [https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems?esab=a&s=troubleshooting&r=3&as=s#w_5-reinstall-firefox here].
WARNING: Do not run Firefox's uninstaller or use a third party remover as part of this process, because that could permanently delete your Firefox data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. These cannot be recovered unless they have been backed up to an external device!
Please report back to see if this helped you!
Thank you.

Firefox keeps getting slower and slower as the day goes on

It's exactly as the title suggests - it works fine first thing in the morning, then gradually gets slower as the day goes on. Last night, for example, I couldn't get on any sites for love nor money - all it kept saying was 'transferring to...' 'loading...' whatever site I was going on, YouTube videos keep freezing etc (I have to keep pausing and waiting for the little grey bar to extend a little; such a trivial thing, yet so annoying! I also unchecked the 'Use hardware acceleration where possible' thing in 'Options', to no avail).
I've done all the usual tests (scan, virus checks etc), all of which have come back perfectly clear. I used Internet Explorer, yet that works perfectly OK, aside from a little slowness in getting a page to load, but I think I'm using a rather dated version of IE (I got my computer September 2012, and this version of IE was already installed on there!), so maybe that's to blame.
I've reset Firefox, to no avail. It's getting on my nerves!! The YouTube part of my problem only started Wednesday night, and the slowness of Firefox started yesterday. As bizarre as it may seem, may the weather be causing the Internet to go slow, as it is unbelievably hot and humid here in the UK at the moment! I remember my Mum saying she had the same problem around this time last year when it was boiling hot!
Any help is greatly appreciated.

'''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Start Firefox in Safe Mode]''' {web link}
While you are in safe mode;
Press the '''Alt''' or '''F10''' key to bring up the tool bar.
Followed by;
Windows; '''Tools > Options'''

Then '''Advanced > General.'''
Look for and turn off '''Use Hardware Acceleration'''.
Poke around safe web sites. Are there any problems?. Then restart.

Everytime I open a new tab, the firefox window gets smaller and smaller.

Every since I updated my Firefox, I have had issues. I love firefox so I would like to have this fixed please :) Well, everytime I open a new window or tab, the Firefox window gets smaller. Kind of like I hit the button by the close screen button. I have to actually hit that button to minimize the screen and hit it again to maximize it. It is sort of annoying. Is there something I can do?

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 that 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.

I want to know how to enable the links that are sent in an email, with each upgrade of Firefox it gets harder and harder to do so. What is the trick to this?

With each upgrade of Firefox, I have a harder and harder time, getting to the links provided in my emails. Some times I am able to trick the link into working, if I continue to to try every link in the email, but most of the time, I just have to give up. I know that I need to change something, maybe in the settings, but I don't know what.
Please help me. I am considering just going back to Internet Explorer.

This did not solve my problem. I can sometimes click on a link (word) provided in an email, that leads to a site, but it does not list the website address!! It works sometimes, providing me with a chance to enable links for this address or enable link (I think basically for just that one time).

When I hit the minimize button on Firefox to use the side by side view with Excel in Windows 7, my Firefox window gets larger and won't give me an arrow in the corner to reduce the frame size.

I can't find a menu to resize my minimized window as it is actually larger than the normal window. The frame of firefox goes right off the screen and will not give me a corner arrow to drag it down to size. Normal window view is just fine. How do I correct this?

It is possible that the screen is too wide or too high and that the scroll bars fall off. 
Open the system menu via Alt+Space and see if you can resize that window. 
If that works then close Firefox to save that setting.

Window sizes and positions are stored in [http://kb.mozillazine.org/localstore.rdf localstore.rdf] in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder].
Delete localstore.rdf or rename the file to localstore.rdf.sav in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder] to test if the file is corrupted.

(caution: do not delete the localstore.rdf file in the Firefox program installation folder)
Note: 
Deleting the file [http://kb.mozillazine.org/localstore.rdf localstore.rdf] will reset the customizations of the toolbars to the defaults. 
You can rename "localstore.rdf" to "localstore.rdf.sav" to test if that solves it. 
Then you can restore the customization by copying "localstore.rdf.sav" to "localstore.rdf" if it didn't work.

When is Firefox Mobile getting mp3 and aac html5 support?

I want to be able to use Firefox for Android to listen to music through Grooveshark's html5 website. From what information I've been able to gather Firefox for Android must still only have ogg hmtl5 support and I don't want to have to use Chrome or the built-in browser just for Grooveshark.

Yes Firefox should be able to play back those files on Android. It is likely that the site is doing user agent sniffing instead of feature detection. You can try the phony extension to pretend to be other browsers. It may allow SoundCloud to work. http://addons.mozilla.org/en-US/android/addon/phony/
If Phony does help then it is an issue with SoundCloud's website.

When I open Firefox I get text and no graphics - how do I fix this?

Graphics are fine on web pages, but I see only text on the home page.

Can you attach a screenshot?
*http://en.wikipedia.org/wiki/Screenshot
*https://support.mozilla.org/kb/how-do-i-create-screenshot-my-problem
Use a compressed image type like PNG or JPG to save the screenshot.
If images are missing then check that you aren't blocking images from some domains.
*Press the F10 key or tap the Alt key to bring up the hidden "Menu Bar" temporarily.
*Check the permissions for the domain in the currently selected tab in "Tools > Page Info > Permissions"
*Check "Tools > Page Info > Media" for blocked images
*Select the first image link and use the cursor Down key to scroll through the list.
*If an image in the list is grayed and "Block Images from..." has a check-mark then remove this check-mark to unblock images from this domain.
Make sure that you do not block (third-party) images, the permissions.default.image pref on the about:config page should be 1.
Make sure that you haven't enabled a High Contrast theme in the Windows/Mac Accessibility settings.
Make sure that you allow pages to choose their own colors.
*Tools > Options > Content : Fonts & Colors > Colors : [X] "Allow pages to choose their own colors, instead of my selections above"
Note that these settings affect background images.
See also:
*http://kb.mozillazine.org/Website_colors_are_wrong
There are extensions like Adblock Plus (Firefox/Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images and other content.

Whenever I use Firefox, I get dozens and dozens of additional junk emails. I don't have this problem with IE8. Do I need to make a setting change to Firefox?

I mainly use IE8 so that I don't have the junk mail problem. I use yahoo mail.

Which problems do you have on that website?
Clear the cache and the cookies from sites that cause problems.
"Clear the Cache":
* Tools > Options > Advanced > Network > Offline Storage (Cache): "Clear Now"
"Remove Cookies" from sites causing problems:
* Tools > Options > Privacy > Cookies: "Show Cookies"
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).
* Don't make any changes on the Safe mode start window.

Hello,
Some problems with Flash video playback can be resolved by disabling hardware acceleration in your Flash Player settings. (See [[Flash Plugin - Keep it up to date and troubleshoot problems|this article]] for more information on using the Flash plugin in Firefox).
To disable hardware acceleration in Flash Player:
#Go to this [http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues Adobe Flash Player Help page].
#Right-click on the Flash Player logo on that page.
#Click on '''Settings''' in the context menu. The Adobe Flash Player Settings screen will open.
# Click on the icon at the bottom-left of the Adobe Flash Player Settings window to open the Display panel. [[Image:fpSettings1.PNG]] 
# Remove the check mark from '''Enable hardware acceleration'''.
# Click '''Close''' to close the Adobe Flash Player Settings Window.
# Restart Firefox.
This [http://www.macromedia.com/support/documentation/en/flashplayer/help/help01.html Flash Player Help - Display Settings page] has more information on Flash Player hardware acceleration, if you're interested.
Does this solve the problem? Let us know.
</blockquote>
thank you for responding.
this does not solve my problem, as i mentioned the problem is with the HTML5 player, i've been using flash player since forever and used to open up to 50 tabs without having any problems, with the new default html5 thingy i cannot open a couple of tabs without the browser dying slowly.. my original question was how can i disable the HTML5 player and make the flash player be the default player

You can check for problems caused by recent Flash updates and try these:
*disable protected mode in Flash 11.3 and later
*disable hardware acceleration in the Flash plugin

Firefox gets slower and slower over time.

I have been using firefox for some time, Like it better than Safari generally, but I've noticed (and it has gotten worse with 3.6.x) that if you leave FF running for extended periods of time it gets slower and slower, does not seem to matter if add-ons are installed or not, and it gets REALLY bad after going in and out of flash based apps/games a couple times. It is not just a mac problem as this behaviour also happens on windows xp or newer, but windows OS needs to be rebooted daily anyways so most people won't notice.

Proceed with [[Basic Troubleshooting]] first of all.
You could also try running Firefox in [[Safe Mode]]. If it functions properly in that configuration, then one of your add-ons is the culprit.

When I first open firefox it is fast but as I surf it gets slower and slower them stops, I have to close it and restart. what do I need to do to fix this?

I start of using Firefox 7, as I surf or stumble it gets slower and slower loading pages till it just starts to freeze up. I have to shut down firefox and restart. This only happens after 3 or 4 web pages.

As suggested I went to Control Panel & chose Add/Remove Pgms. Now, near the bottom was Windows iLivid Toolbar. I then hi-lighted it & removed it. The date it was last used seemed to be when my problem started. I am not a big user of toolbars (except the main ones); so I had no issues about deleting one that I did not recognize.
Then I opened up Mozilla again & changed my Home Page, using Tools then Options. I closed out Mozilla, then brought it up again & my new Home Page was showing just fine. Wow! What a relief it worked. I hope it lasts. Thanx Firefox !

Firefox getting slower and slower

firefox has been working great all of a sudden pages are taking longer and longer to load and unable to load search engines,in firefox or explorer. search engines work fine on second computer.

I am having the same problem as GTA_doum. Firefox gets slower and slower if left open for a day or two, and then when I restart Firefox it's fine for a day or two and then gets slower and slower. Help!

Firefox gets slow after awhile and also hangs and sometimes i get plugin-container.exe error

Hello, it's a while that Firefox gets slow and also hangs and sometimes i get plugin-container.exe error...
I'm not sure but maybe it often happens after monitor goes to Screen Saver or after it turns off...
Error signature
AppName: plugin-container.exe AppVer:1.2.9.3951
ModVer: 5.1.2600.5512 Offset:0000100b

You can run Java in Firefox.exe instead of plugin-container.exe, but I'm not sure that actually would be better than where you are now.
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the filter box, type or paste '''java''' and pause while the list is filtered
(3) If '''dom.ipc.plugins.java.enabled''' is true (bolded), right-click it and choose Reset (or double-click it to toggle).
If that value already is false, you might be having a problem with another common plugin such as Flash.
