Firefox freezes when I access my add-ons page.

Firefox freezes when I access my add-ons page. I must use Task Manager to unfreeze it. Some add-ons (AdBlock) still work. Others (NetVideoHunter) don't. I would like to remove all the add-ons and start fresh, see if it makes a difference, but when I access my add-ons page to press the "Remove" button, FireFox freezes--so what am I supposed to do? I like Firefox because it's simple and generally glitch-free--until now.

hey furdeal - if you'd like a fresh start, you can simply [[Reset Firefox – easily fix most problems|reset firefox]]. this will keep your bookmarks, passwords & history but will remove all extensions and custom preferences...

When I update to the latest version I cannot access the add-ons page or request help because neither page will load. My Weather channel add-on was NOT piced up when updating to the latest version. Why problems with improved latest version?

I have twice downloaded the latest version in the last month. Each time I encountered the same problems. the Weather Channel add-on I have did NOT appear in the latest version. When I tried to access the Add-Ons page under the Tools header it would not load. When I tried to contact Mozilla from the Help header it would not load
When I open a web page from Bookmarks it is painfully slow to load.
This is NOT an improved version. I have been using Firefox for years without problems; I prefer it to Internet Explorer. However the latest 'improved' version may change my mind.

The problem is that the Add-ons Manager tab when opened the first time, is on "Get Add-ons" section and that must be downloaded from the Add-ons server which might be overburdened.

Firefox crashes when I click on "Add-Ons" from menu tab

Every time I click on "Tools" in the menu bar and then click on the "Add-ons" tab, Firefox immediately crashes and a crash report shows up asking if I want to submit the report. This only started happening after I recently installed a bunch of add-ons to my browser. I want to uninstall some of the add-ons but unfortunately I cannot even view the "Add-ons" page now because it keeps crashing every time I try. I have tried restarting my browser as well as my computer many times and still get the same crash error.

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.

This can be a problem with the file(s) that store the extensions registry.
Delete the files extensions.* (extensions.sqlite, extensions.ini, extensions.cache, extensions.rdf) and compatibility.ini in the Firefox [[Profiles|profile folder]] to reset the extensions registry. 
New files will be created when required.
See "Corrupt extension files":
* http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the Tools button at the left side of the Search Bar (or click the "Find Updates" button in older Firefox versions) to do a compatibility check or see if there is an update.

I keep getting a Yahoo DNS error handler page, and can't even access the add-ons page to disable it because it redirects me to the Yahoo DNS page immediately

I have already seen some suggested solutions to the problem of this extremely annoying Yahoo DNS error solutions page, but they involve going to the add-ons page of firefox and disabling various add-ons. The issue is that even when I try to go to the add-ons page I get immediately redirected to the Yahoo DNS solutions page again.
I have cleared my browser history and cache, hoping it would help, but nothing. Extremely annoying as I never installed anything - it simply started after a Firefox upgrade.
Any help much appreciated.

Open the Help menu and choose Restart Firefox with Add-ons Disabled. Remove any offending extensions. For details, see the "Uninstall from Firefox Safe Mode" section of the following article.

When i open the add ons page in firefox the pages do not display correctly the pages only show text and are in lists

when i click on the add ons tab the page does not show correctly. There are no graphics just text. It is difficult to view the page details. If you click on a link within the page the next page opens with exactly the same problem. All other tabs and pages open and display correctly

Hi,
If you're using a theme you can try to temporarily switch to the '''Default''' theme in Tools > Add-ons > Appearance. If the problem persists, please check if this happens in [https://support.mozilla.com/en-US/kb/Safe%20Mode Safe Mode]. Safe mode disables the installed '''Extensions''', and themes ('''Appearance''') in '''Tools''' ('''Alt''' + '''T''') > '''Add-ons'''. Hardware acceleration is also temporarily disabled - the manual setting is '''Tools''' > '''Options''' > '''Advanced''' > '''General''' > [https://support.mozilla.org/en-US/kb/Options%20window%20-%20Advanced%20panel?as=u '''Use hardware acceleration when available''']. All these settings/options/add-ons can also be individually or collectively disabled/enabled/changed in Firefox normal mode to check if an extension, theme, option or hardware acceleration is causing issues. Disabling/enabling hardware acceleration, and some types of add-ons in normal mode may require a Firefox restart.

Have you read the [[Firefox crashes when viewing Youtube videos]] article?

I want to completely remove the advert ban application. Even though I have the latest Firefox version I cannot access my add-ons. How do I resolve these issues?

I have Firefox version 7.01.

You should be able to see the add-ons and plugins by using
* '''Tools -> Add-ons''' (Or you may use keyboard shortcut '''Ctrl + Shift + A''' )
** then once in Add-ons Manager select the tab '''|extensions|''' or '''| plugins|'''
What is the ''advert ban application'' that you refer to ? this may be some program that was installed on Windows XP and may need to be removed from the control panel of XP, or is it part of a security suite ?

Why did I download FireFox 11, when none of the add-ons work on it?

I was using Google Chrome to use on Facebook. I had problems with it and multiple users told me the way to go was to switch to Firefox. I downloaded it and while reviewing the get aquainted information, it seems most of the add-ons say" Not available with Firefox11. Why did I bother if their newest product does not support their own add-ons?

Why start out as a new Firefox user with a '''''Beta''''' version that is still two weeks away from being released?

Firefox freezes when going to a site or page that requires Flash Player, such as YouTube. I have the most updated version of Flash. Is there a solution to this problem?

I'm having trouble visiting sites or pages that require Flash Player, Firefox will just freeze when they're partially loaded and it will stay frozen until I close Firefox. This will happen with any page that uses flash player. I can disable it, but then I can't access the content which requires Flash Player, have to use a different browser and I'd rather just use Firefox.

Hello,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
Did this fix your problems? Please report back to us!
Thank you.

Firefox crashes when trying to open Add-Ons menu

Firstly the search bar that s part of the Google toolbar would not search what i typed in it, it would simply do nothing. After I discovered this I decided to go look at the add-on or something in the add-on menu under tools. When I clicked "Add-On" firefox froze and has continued to do so everytime I click that option resulting in me having to force the program to close.

I have successfully disabled the addons by going this route;

Firefox freezes when attempting to interact with a page.

Whenever I start up Firefox (4beta7 portable) it acts normally. I can visit web sites without a problem. However as soon as I click on any page (including about: pages) it freezes forever. I have to use Windows to manually close it with the program is not responding box. I have a feeling that it might be related to one of the plugins I installed immediately before restarting

Unable to access Add-Ons Page after Firefox Security Update.

When I click the add-ons page (after installing the latest Firefox security update) (6.0.1 I think) I get a message that Firefox would show me nifty add-ons IF I WERE CONNECTED TO THE INTERNET. I am connected. Only Firefox pages won't connect.

Hi
such things are often due to cookies - you can either clear all cookies, or use the filter/search to find 'live' and/or 'hotmail' ones - via Safari-Preferences-Security-Show Cookies.
Then quit safari & check again.

When I try to access my add-ons, firefox freezes and I have to shut it down

I never used to have any problems but started getting script errors. I have repaired this but now I cannot access my add-ons. Every time I click on it in the Tools menu, Firefox completely freezes and I have to shut it down.

Do you have the Personas Plus 1.6 extension? If you do that one is known to conflict with Google Toolbar and cause the sort of problems that you are having.
Try starting Firefox in [[safe mode]] to see if you can access the add-ons manager. If you can and have Persona Plus, try disabling/uninstalling it whilst in safe mode. If you do not have that add-on, another one may be causing problems, to try to track down which one see [[Troubleshooting extensions and themes]].
Another thing you can try is deleting the files that store details on installed add-ons, if one of them is corrupt it can cause problems. To do that first open your profile folder, for how to do that see the [[profiles]] article.
After you have opened the profile folder, close Firefox and delete extensions.cache, extensions.rdf, extensions.ini and compatibility.ini. When you re-start Firefox those files will be re-created.

None of my addons or extentions work any more since installing 3.6.6. When I go Tools/Add-ons it just goes 'ding' [makes an error noise] when I click on any oth the options and then firefox freezes up.

Delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini) and compatibility.ini in the Firefox [[Profiles|profile folder]] to reset the extensions registry.
See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
If you see disabled extensions that are not compatible on the next start in "Tools > Add-ons > Extensions" then click the "Find Updates" button to do a compatibility check.

A site I need for consulting purposes requires an add-on known as "Intranet for Firefox". When one accepts the add-on installation, a return message is displayed claiming that it cannot be found. At this point, I have to use IE to access the site.

A site I need for consulting purposes (http://www.aegtelecom.com.pt/) requires an add-on known as “Intranet for Firefox”. When one accepts the add-on installation, a return message is displayed claiming that it cannot be found. At this point, I have to use IE to access the site. However, being a steadfast Firefox user, I would prefer to use Firefox for this purpose.

http://www.aegtelecom.com.pt/contactos 
Have you tried contacting that web site's support department for help with that issue? 
If that web site can't find the add-on it says is needed, they need to fix that problem with their servers.
Or you can try using IE Tab2 to run IE in a Firefox tab.
