When I go to Tools Add-ons, nothings shows under Add-ons, Extensions, etc.

The only clickable item there is "check for updates." My add-ons are all working, but none show up. Same for Extensions, Appearance, Plugins, Services.
I don't know how long it's been this way, because I've had no need to check until last Friday, when I picked up some malware that slides open a tab from the right-hand side of my screen with "Hot Deals" on it.
Firefox's "Automatically add" option tells me that listed below are my add-ons (though I can't see them in my own Add-ons tab). There are several there I don't recognize at all, but I have no idea how I can remove them without that page properly loading.

Thanks for any help you can offer.

If it works in Safe Mode and in normal mode with all extensions (Firefox/Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit)
*If you have many extensions then first enable half of the extensions to test which half has the problem.
*Continue to divide the bad half that still has the issue until you find which one is causing it.

When I click on tools/add-ons, add-ons will not come up so it cannot be accessed.

I am trying to uninstall extensions that I think are causing problems with Firefox but I cannot get to add-ons. When I click on tools/add-0ns there is a brief flash and then nothing.

You can delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini, extensions.sqlite) 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 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.

The add-ons window does not appear when I go to Tool Add-ons.

A notice says: "A running script is insufficient...." often appears and I can not open my add-ons when I go to: Tool>Add-ons

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

Hi bluefleetwood, the options on this site are Mozilla's current support options for Firefox.
Try the addons site again in case it was a temporary problem, or if it's an SSL certificate problem, please indicate what the page says about the certificate.
You have a serif font for most of your Firefox UI. Can you let us know what font that is? Most likely it was selected in your Windows display settings (right-click Desktop, then Properties) and appears on many of your applications. It appears to be the same one for Menu text and Message Box text.

Firefox locks up then crashes when I open the Tools-Add Ons page

Hi - Just updated today with automatic 6.0.1 update and once I did, Firefox killed Adobe Reader. I fixed that but then found that opening the Tools, Add-Ons page locks up Firefox for a few minutes, then crashes it.

Hello Ted.
Although possibly not related to your problem, I will remind you that the version of Firefox you are using at the moment has been discontinued and is no longer supported. Furthermore, it has known bugs and security problems. I urge you to update to the latest version of Firefox, for maximum stability, performance, security and usability. You can get it for free, as always, at [http://www.getfirefox.com getfirefox.com].
As for your problem, you may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
If you want support for one of your add-ons, you'll need to contact its author.

How can I quickly and easily make Firefox on my newest computer the same as all my others (add-ons, extensions, etc.) without individually adding each one?

I have several computers throughout my house and work, but mainly use my "Desktop-MAIN. " I frequently add different add-ons, scripts, extensions, etc. as the need for one arises. When the time comes that I am using my laptop in bed, or my sons computer in the den (whatever) I find that they are missing many of the cute doodads I have become accustomed to on MY desktop computer. In Firefox I used FEBE backup, which would backup EVERYTHING, including extensions, add-ons, etc. I just had to take it to my other computers and run FEBE, import the backup file and "whala!" My browser had all of the add-ons and things that my main computer had - w/o having to manually add each one.

Just connect the new iPod to your computer and setup the iPod via iTunes (instead of via wifi).
If you want to copy all the infor from an old iPod touch to the inew iPod see:

My Tools Option will not show, clear all, cancel, apply etc. Every Tab under Options is blank except "General"

When I click on Tools, then Option, the pages are all blank. The only one that works is the General Tab. At the same time, the two options on the bottom of the General tab do not have text, just empty buttons. I first realized this when I tried to clear history and Cookies after I have been un able to SIGN OUT of my hotmail account on Fire Fox. Everytime I sign out, it signs me back in when I hit Hotmail
== User Agent ==
Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; GTB6.4; AskTB5.4; BO1IE8_v1;ENUS)

Do you have that problem when running in the Firefox SafeMode?

While updating Ipod we now have a blank screen and when connecting to itunes the ipod is not showing under devices

While updating ipod touch we now have a blank screen. I have updated itunes but am unable to sync because the ipod does not show under devices. I have tried shuttng down and restarting but only have a blank screen or ap0ple logo. Sometimes the screen shows connect to itunes but that has been it.

I have the same problem, after upgrading my itouch to iOS6, it doesNOT respond to anything, apple logo stays on the screen all the time and does NOTHING! restore does not work either.... i hope we can get an answer from someone soon... apple support did not have an asnwer.

I can't get firefox (Linux) to use flashplayer. I've installed a dozen times but it doesn't show up in tools/add-ons.

I've tried installing flash player a dozen times, with both the instructions on the adobe page and the mozilla page. I'm running Fedora Core 11 with Mozilla 3.5.9. I've gotten "libflashplayer.so" and copied it to every "mozilla/plugins" directory on the drive. It does not work and is not listed when I bring up "tools/add-ons." One instruction said to copy "flashplayer.xpt" to the "mozilla/commponents" directory, but the download included no such file and I have no such directory. (Probably pertains to an older version.) I've tried downloading it with the .tar, .gzip, and yum; all with the same result. It doesn't work online and doesn't show up in my plug-ins.
== This happened ==
Every time Firefox opened
== Only time I've tried to install it.

I had a problem with Fedora 15-64bit + Firefox 64bit + flash player plugins. I finally found that the plugins must be put in: /usr/lib64/mozilla/plugins.
I downloaded the 64-bit version of the flash plugins at : http://labs.adobe.com/downloads/flashplayer10_square.html Decompressed it and move the file libflashplayer.so to /usr/lib64/mozilla/plugins (you need to be super user to do that). Restarted Firefox and it worked ! My guess is that if you use 32-bit plugins then you must put them in /usr/lib64/mozilla/plugins-wrapped but I didn't try.
Arg ! It took me the whole evening to find that !

Ran the 'Refresh' mode, now nothing is compatible with my version of firefox? No Add-ons, Extensions or Themes. Please help me get back to what I had.

I opened Firefox, and I had a bar along the bottom saying it needed to be optimized, so I could refresh Firefox. I understood that it would take it back to its original state, but I thought that I could add things that I wanted. But when it was "Refreshed", I could not add anything. Themes are "Not compatible with my version of Firefox". Add-ons do download, but I cannot install them. It takes me to a page that is too confusing for a non-tech person like me (a windows page that wants me to find the program that will install it). So I gave up (I also don't have alot of time to fix this). I checked for "updates" hoping that I could update the version and then add a theme, add-ons, extensions, etc. But it is up-to-date. Thank you for your help.

Normally, when you try to install an extension from the Mozilla Add-ons site, you get a progress bar that drops down temporarily from the address bar, and then a pop-up dialog asking you to approve the installation. Do you get either of those or just nothing happens?
As an example: https://addons.mozilla.org/firefox/addon/adblock-plus/
Could you test with the avast! extension disabled in case it is blocking these normal actions? You can do that on the Add-ons page. Either:
* Ctrl+Shift+a
* "3-bar" menu button (or Tools menu) > Add-ons
In the left column, click Extensions. Then find avast! on the right side and click Disable.
Often a link will appear above a disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.
Any difference? Are other sites still a problem?

My McAfee SiteAdvisor add-on is activated in the Tool-Add-on menu but doesn't appear in the Add-on Bar.

My McAfee SiteAdvisors is activated but doesnt show in the add-on bar. I double checked the situation under « Tool, Add-on, Extensions » and the add-on is enable. Also the « Add-on bar » is activated.The green McAfee SiteAdvisor button dissapeared after firefox update 16.02. I updated to 17 in case it would resolve the problem with no success. McAfee is still working by giving a warning page if I try to go on a suspiscious site.
Also in google search result I no longer get the little McAfee evaluation icones.

suggest you to re-install siteadvisor pluggin or u can find it under customize toolbar options...

An unknown website just appeared in my 'exceptions' list (Tools Options Security "warn me when sites try to install add-ons"-how could this happen?

downloaded Firefox onto friends' laptop last night. Found it necessary to place two websites in the (afore-mentioned) "Exceptions" category. shut down/re-booted three-four times over the next few hours before shutting down the laptop and going to bed. Booted up this am and, WHOA!-suddenly my menu/toolbars have new, undesired toolbars(?) search boxes(?): the search box, if I remember right, was labeled "My Web Search sponsored by iwon!" Whilst eliminating the intruders I became aware that by some unknown means I had fetched up on some webpage I've never heard of and had no reason to go to-( the very top of my display (above the menu and address bar) read: 'reason upgrade Search' (separated by a line symbol I can't reproduce here), then 'Musician's Friend' ....HUH? (feeling like Dorothy w/o a tornado transport). So I finish getting rid of the invaders and check out my History to try to figure out how I wound up at this website. my history indicates the last site I visited before going to bed, then 'aclk' (www.google/aclk? followed by a string of mixed symbols letters etc. Then 'redirect' (www.rkdms.com/redirect?c=....and a string of numbers and letters. Then the website"reason upgrade Search (?) Musician's Friend " then 'redirect.jhtml' (www.search.mywebsearch.com/mywe.........) Them 'Firefox Web Browser& Thunder....' still no clue how or why I wound up at that site..didn't go there, (not of my volition, anyways!!) so im checking my security settings and in Tools>options>Security>advanced> in the "Exceptions" category of "Warn me when sites try to install add-ons" is a website I've never heard of (getpersonas.com) and DID NOT enter!!!!!!!.Need to know how this could happen, how to prevent recurrence and how hard should I hit the panic button because right now I'm totally freaked!
== today

These prefs get set to an empty String once the sites have been added to the whitelist if the pref is not empty if you open the exception window.
Tools > Options > Security : "Warn me when sites try to install add-ons": Exceptions
You can reset these prefs on the about:config page.
xpinstall.whitelist.add - addons.mozilla.org
xpinstall.whitelist.add.36 - getpersonas.com
To open the ''about:config'' page, type '''about:config''' in the location (address) bar and press the Enter key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.

Nothing shows when going to Tools Add-ons Extensions to delete Yahoo Toolbar.

When going to check my extensions, nothing shows up. All i want to do is delete these crappy toolbars ie/yahoo, vuze.
Nothing seems to be disabled, no recent updates changed anything, but for some reason, I'm just thinking i will have to reinstall Firefox, enable my IE again, and re-download firefox.

Reinstalling Firefox most likely won't help if there is a problem with the current profile.
See:
*http://kb.mozillazine.org/Uninstalling_toolbars
*http://kb.mozillazine.org/Uninstalling_add-ons
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.
See:
*http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox

I updated Adobe flash and when I re-opened firefox all of my bookmarks, add-ons, extensions, history were gone. How do I retrieve?

When updated Adobe flash, I was asked to close the browser window. I complied and when I re-opened, firefox was different and all of my stuff was gone.

go to Tools Menu -> Add-ons -> Extensions section -> Disable and Remove the add-ons that look unwanted or suspicious -> Enable trustworthy add-ons -> Restart Firefox.

When I go to Tools Add-ons, nothings shows under Add-ons, Extensions, etc.
