xpinstall.signature.Required false but firefox is still blocking the pentadactyl plugin to be installed

Hello everyone, I have ' tries to install the plugin pentadactyl (Ref: http://5digits.org/nightlies) , but Firefox keeps blocking because it is not signed. About: config variable xpinstall.signatures.required is set to False, what else am I missing?

Thank you very much

Addon signature is applied in firefox since version 48 release - mentioned preference is no longer in use: https://wiki.mozilla.org/Addons/Extension_Signing

If you want to run unsigned addons please use rather developer edition of firefox: https://developer.mozilla.org/en-US/Firefox/Developer_Edition

  • Firefox could not download the search plugin from

    I installed Firefox 24.0 recently and I am trying to install open www.youtube.com youtube Search Engine by clicking on Add "YouTube Video Search" in the search bar, but I get the following error message:

    Download error
    Firefox could not download the search plugin from:
    http://www.YouTube.com/OpenSearch?locale=en_GB

    What is a Firefox problem, or a youtube error?

    Thank you for your response.

    I don't want to install addon for youtube search. I just wanted to know if I can install the search engine for youtube as before.

    After a few readings on the internet I found that the search engine is described by a small XML file which is available through a link on the page. All other pages with operation generates the search engines like Wikipedia or IMDb content is XML refers to XML file. But the link to youtube opensearch descriptor points to an opensearch.osdx file.

    I don't know if it's the extension, or if he did not support tag inside but Firefox is not prepared to handle it and add youtube to search engines.

    I found this page: http://www.tobtu.com/customsearch.php I copied the relevant tags in the fields of seizure and added YouTube video Srearch. Now, it works fine.

    But the question remains: is it Firefox that can not handle the descriptor of opensearch sandard of youtube or youtube.com which provides a defective descriptor?

  • Smartphones from blackBerry Bold 9900 stole, but it does not block the service provider

    Hello

    My phone got stolen, but it does not block the service provider. All they did was disable the sim card.

    BlackBerry protect now cant work because the phone cannot connect to the network.

    Don't know what else to do

    It is each carrier as they will blacklist the device or simply to block the SIM card.  The good news is that no one can rack up charges on your account using your old phone.  Now when you get a new, open a BlackBerry Protect session and cancel the old phone.  You can then connect your new phone and restore your contacts.

    I hope that helps you.

  • Installed CC Cleaner. It screwed up my Firefox. I have removed CC Cleaner, but Firefox is still screwed. Cannot make hotmail or gmail in Firefox

    I installed CC Cleaner and ran cleaner and registry.

    Now I can't use firefox on a variety of sites. They can do, but they do not work properly. I left all the javascripts, but I can still see my destination page (for example can connect to hotmail), but cannot go further (for example, cannot enter the Inbox)

    I uninstalled CC Cleaner, but problems remain.

    Should what settings change back? System Restore does not apply, and I can read my mail in IE (which I despise do), so how can I reset or correct my Firefox settings? I tried, but failed. Thank you!!

    You are welcome

  • My iMac freezes, but I can still move the mouse

    My iMac (3.06 GHz Intel Core 2 Duo, new HDD 4 TB, 12 GB of memory running 10.9.5) freezes randomly just straight up. I can't tell you how or when this happens. There is no model it. I can move the mouse, but click on anything. I am usually under Safari and Firefox when this happens, and I have a few windows/tabs open. I'm also in Word when this happens sometimes. But really, I don't test the limits of this computer so I can't understand why it would freeze upwards. I got it in the store four times and this is my third hard drive. I am currently using about 1 TB or less than my 4 to drive, it's not a question of space. Guys my computer store say it might be a software problem, but I don't see how that nothing is added or downloaded since it began. My old computer died in February, so I got an iMac refurbished with a brand new HD and the new ram. That's when the problems started. I replaced the computer with this one (another refurbished with a brand new HD) and still had the problem. Now I just got a new 4 TB HD hybrid (I love, BTW.) (Very fast), and the problem persists. Any ideas? Thank you. My computer guy say that their only idea is to wipe the drive clean and manually put items on one by one. Sounds expensive and has not guaranteed to solve the problem.

    A question, if your 'computer' man an authorized Apple service provider. If it is not you, please, do not take the computer to him. Find an Apple authorized Service provider in your area, and from there take someone who is well trained and certified by Apple. If you don't know any, click Apple authorized Service Provider Locator

  • Some of my favorites live reloading is no more, manually or automatically. I tried safe mode and reset Firefox and still have the problem. Repairable?

    I subscribe to 19 Articles in the form of live bookmarks. A few months ago, one of the blogs started not refresh the list of messages. Now a second blog is no longer updated. I tried the dynamic 'Charging bookmark' option (from the book live mark dropdown and since the "Show all bookmarks" menu and it will refresh the list.) If I visit the blog, I get the last commit, but he never shown in the RSS feed. I tried to open Firefox in safe mode to see if the modules are at the origin of the problem and there is no change in the behavior of the stream. I also tried to reset Firefox and it does not work. What else can I try?

    Live bookmarks magically started working again! Had to be something with the blog I was following how I've changed anything recently.

  • ICS Android on Galaxy note, tap the link in a Web site, but firefox has only highlighted the link but did not open this link

    When I was with android 2.3.5 I have no problem with the Web page that has links that I touch just the link on the screen and it goes.

    However, upgraded to ics, when I tried to touch the link on the same Web page, the link highlighted in yellow, but firefox do not go to this link page.

    I tried to touch the same link to many times and suddenly firefox grabs my statement and it is up to the page of the link.

    It is very annoying that I have to repeat touch not knowing when firefox detects my entry and removal.

  • Facebook blocked, but it's still in the reports?

    I have blocked Facebook of my children's accounts using parental controls, but it still shows up in reports as the most used website.  When I try to access Facebook from their accounts, it is effectively blocked.  I also have PC in the family estate and they don't go on Facebook - or they have an account.  Why the reports tell me they use Facebook when it is blocked and they do not use it?

    Hi Tim,.

    We are happy to help you on your question. I understand that Facebook always shows in the activity reports, even if it is blocked.

    Safe family activity reports will include sites that are visited but blocked. Also, sites that was redirected from other sites, or use a feature of this site (such as the Facebook Like function and share) will add also upward to the activity report.

    Please let us know if you have any inquiries.

    Thank you!

  • My HP laptop says it is not connected to the internet, but I can still surf the web very well.

    All windows applications claim that I am not connected to the internet. So I can't change all the details such as my password or an image.

I tried many things to fix it, I'm not connected to a proxy, I've had this laptop for about a month and he began to do about two weeks ago.

    Hello

    Thanks for posting your query in Microsoft Community.

    According to the description, I understand that you are facing inconvenience when you install Windows store applications.

    Please follow the methods below to solve the problem:

    Method 1: Reset the store of widows.
    This command resets the store Windows without changing account settings or remove installed apps. WSReset.exe is usually located in the folder %%SYSTEM.

    I suggest you perform the steps below to reset the Windows store.
    (1) key press"Windows + R"on the keyboard to open the run window.
    (2) in the run window, type "wsreset. exe«and then click on the button ok . » It will clear all hide all Windows store.

    Follow the method if the problem still persists below.

    Method 2: Temporarily disable all security software, then check to see if that solves the problem.
    Temporarily disable anti-virus software or other security software installed on your computer.

    Warning: security software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.

    Method 3: Run the network troubleshooter

    I suggest you follow the link to perform network troubleshooting.
