• After Firefox upgraded to version 6, just now, my Add-ons Manager crashes constantly when I try to access it. How to solve this problem or downgrade to version 5?

  During the update process, it said an add-on, java console, was not compatible and would be disabled.

  It is a common problem caused by a bug in the process of updating Firefox 6. Fortunately, you should be able to solve it by clicking one of the tabs on the left side of the Add-ons Manager (Add - ons get, appearance, Plugins...).

• How can I get the tab of the Add-ons Manager to stop when I go to my home page of opening? (I hate that!)

  When I go to my home page by clicking the home page (more convenient way to access my most frequently used page), the Add-ons Manager will open in its own tab. I don't like this at all. How can I get him to stop?

  Looks like maybe your homepage has been accidentally updated to include several pages, including the Add-ons Manager. Try to open the Firefox options window and paste the address of just your page field "Home Page".

• Why don't security browser Avira displayed when I search modules in the Add-ons Manager page?

  Why don't security browser Avira displayed when I search modules in the Add-ons Manager page?

  If I search in google, it appears in the list of results, and it displays a add to Firefox"" button.

  However when I click on the "Add to Firefox" button, I get a message "Firefox prevented this site from asking you to install software on your computer" with the button authorize. Why is this and is - it safe to click the allow to install this extension?

  Hi Roberto2525, through the Manager of addons you will only find extensions that their developer chooses to host with mozilla / addons.mozilla.org, addons not they want to distribute themselves.

  the warning message you are seeing is normal and is displayed before the installation of each addon. as the firefox addons are always free to do almost everything that is possible, you must install the addons which authors you trust (extensions hosted on addons.mozilla.org are carefully controlled until they are published).

  from 41 firefox, firefox will require that hosted also outwardly need addons must be signed by mozilla, after what they've been through a few basic checks. so, if you install the extension avira and it says something like "could not be verified for use in firefox," then if please contact avira as well and ask them to get their signed addon: signature of the add-on in Firefox

• Add-ons Manager crashes Firefox when I open it.

  I use Linux Mint 10 and Firefox 4b11pre, although this has happened since at least b9pre. I'm under Fx in my home folder as it is downloaded from Mozilla, not a PAL. This happens on 'stable' beta versions, but also the "pre" versions I used to be able to "suck" the databases with Bleachbit program and the problem should go away... for a while. Now it's more emotional.

  In addition, and I think it's important, all of THE modules are working properly. Everything works except that I can't open the crib of the add-on.

  The add-on Manager (huge, heavy and unresponsive) new simply stops working. He does not or partially loads and darkens in the browser, which means a program is not Linux. I then have to force to leave Firefox.

  If I crash reporting active I am never asked to submit a report.

  In this case completely at random. It is not associated with any particular add-on I can say. I spent several hours trying to diagnose this problem without success.

  Things I've done:

  1 build a completely fresh profile. I did it many times combining many different situations, and the problem still happens. It happens with the default settings when I change only the settings of the Preferences dialog box, and when I change the settings via subject: config. I also used the switch to safe mode to reset all settings, but it still happens. Similarly, I have re-downloaded Firefox itself, 'pre' and 'stable' for fear of corruption by updates, that's already happened, but this does nothing either.

  2 safe mode. If I chose to disable all modules in the safe mode dialog box, restart Firefox Add-ons Manager work. At some point, I have approximately 30 active modules, mainly the standard (Adblock, No Script, etc.) and although I am simply playing with.

  Now, when I start to activate the Add-ons, the Add-ons Manager work. I can turn on, say, 5 at a time, completely at random, and it will continue to work until I get to about 25, then it dies. I deleted all modules except those approved by Mozilla Add-ons Web site out there. Then with approved all the Add-ons (and still a manager does not) I disabled all add-ons, restarted and activated one by one. Enable, restart. Enable, restart. Then, randomly, it just stopped working and freezes. I made this several times and totally random orders. He's not on any Add on specific and it always happens between 21 and 27 active cases. You can imagine how frustrating it is, because the Add-ons Manager has no way to activate the mass, or the number of Add-ons.

  Finally, I don't receive any red flags in the error console and has exhausted my knowledge of debugging in Firefox. I get no error when running the terminal either. As I said, all the modules are working properly. I did the other combinations of things, if it's a logical off shoot of what I mentioned above, then I probably did. I've looked everywhere, Bugzilla, Google, Add on bugs, etc. anything.

  Sorry it was so long, if I can't manage my Add-ons there is simply no reason to continue to use Firefox, but as is normally the best browser autour, I don't want to deal with this option. Any help would be greatly appreciated.

• Why nothing appears when I select "extensions" in the Add-ons Manager?

  Somehow, an extension/app called Coupon Saver (which I never did and which is really annoying) has been installed. I've uninstalled it on my laptop, but it must also be removed from FireFox. However, whenever I'm in the 'Extensions' Panel in the Add-ons Manager, nothing comes at all. It shows all the tabs on the right with "Extensions" highlighted, but beside that is nothing else than a blue screen. Why is this and how can I fix this so I can removed the form for adding offending my browser? Thank you for your time.

  It is possible that there is a problem with the files that store the registry extensions.

  Delete the files (extensions.sqlite, extensions.ini) extensions.* and compatibility.ini in the profile folder of Firefox to reset the extensions registry.

  • https://support.Mozilla.org/KB/profiles

  New files will be created if necessary.

  See "extension corrupted files:

  • http://KB.mozillazine.org/Unable_to_install_themes_or_extensions
  • https://support.Mozilla.org/KB/unable+to+install+add-ons

  If you see disabled extensions or is not compatible in ' Firefox/tools > Modules > Extensions ' and then click the Tools button, on the side of the left end of the search bar to check if there is an update available compatibility.

  If this did not help, then also delete the addons.sqlite file.

• I have install an add-on for Firefox, but it does not appear in my list of Add-ons Manager, and after I restarted Firefox, it went.

  I try to install 1-Click Youtube Video dDownloader, which is supposed to add a download button to Yuotube video pages. I go here:

  https://addons.Mozilla.org/en-us/Firefox/addon/1-click-YouTube-video-download/

  and I click 'add to Firefox '. It gives me the window "install now". I click on 'Install now' and it is said that Firefox has to restart and it will be installed when Firefox opens again. If I click "Restart now" and restart Firefox. Then I go on Youtube, but no button. I check the page of the Add-ons Manager, and I see that it is installed in the extensions. So, if I go to the page and click 'Add to Firefox' once again and restart once again, go to Youtube, the download button IS there, and it works perfectly. But if I exit and restart Firefox, the download button is once again absent, but the extension is always installed. Why this extension works only when I restart twice, and then it disappears again?

  When the button does not appear, but the extension is marked as active, try to reload the page to Youtube without using the cache by pressing command + shift + r to see if that triggers the extension to insert the button.

  If it remains inconsistent, I would like to ask the developer to Add on to their Contact page: http://www.clickvideodownload.com/contact.php

• Added Yahoo Toolbar and Add-ons Manager no longer shows the extensions one I can't access the function "get addons".

  I added a Yahoo toolbar for Firefox that has been customized for Frontier Communications. I Ghostery installed as an add-on, and she flashed a message that Yahoo toolbar confused its effective functioning and I would like to disable or uninstall the toolbar. I open the Add-ons Manager to do and much to my surprise he now showed no extension at all, but they all seemed still works! All my plug-ins appear when I look on the Add-ons Manager. I checked the "Get function modules and it tries to load but does not succeed." I am running Firefox 10.0.2.

  Please also try to delete the extensions.* files in the right out of the Firefox profile folder. Firefox will recreate the files and information. Please note that at the next startup, Firefox can request permissions, opening several tabs with each tab corresponds to a detected extension. Select allow the installation, click continue, but click on restart only on the last tab. You can also try to leave out the suspects without selecting modules and continue. I hope it will solve the problem.

  Files & Firefox profile folder

  Another way would be to try a new profile. Firefox stores the data from profile/personal separately from its installation folder. If the new profile is correct, you can later copy/replace files of the old profile in it, for example. the places.sqlite who holds history + information of favorites, the folder of bookmarks which has backups dated only bookmarks, signons3.txt + signons.sqlite which are necessary to restore successfully a saved website names to user/passwords etc. Please note that in this case, although it is also possible to copy the extensions it may be preferable to install again via Tools > Modules search box or AMO.

• Add-ons Manager keeps loading

  When I try to use the Add-ons Manager in the browser, I can never progress beyond the stage of "Loading"... ». I still have the download, search for them and the Options available. I waited 5-10 minutes to see if the loading ends. So far, he has not.
  I don't remember what theme I am running. Add-ons only I remember are NoScript, KeyScrambler and Privacychoice. All my modules and must be current as of 31/08/2011.

  By default the "Get Add-ons" tab is selected if you open the topic: addons page (Firefox/tools > Add-ons).
  
  This page tries to load content from the Mozilla server and that can take some time especially if the Mozilla servers are busy.
  
  You can click on the tab 'Extensions' to see the installed extensions or one of the other tabs to see other add-ons installed.
