Why lightning installed through Firefox Add - ons official was supposed to be unsigned.

When I'm gone on the official Web site of Firefox Add-on (https://addons.mozilla.org/en-US/seamonkey/addon/lightning/) & tried to install Lightning in Firefox 49.01.1 I received a message that Firefox prevented this site to install an unverified add-on. As a result, I realized that Firefox would not an add-on not verified or not signed to be published on the official website.

As the description says lightning is only for Thunderbird and SeaMonkey (as it is an e-mail client built into the suite) it's a calendar.

https://addons.Mozilla.org/SeaMonkey/addon/lightning/versions/ Works with SeaMonkey 2, 42-2, 42. *, Thunderbird 45.0 - 45.*

Section for desktop Firefox is https://addons.mozilla.org/firefox/ you were in the section of SeaMonkey.

  • Firefox Add - ons in any way interfere with a VPN?

    I recently ordered a VPN. Itgood, but has its ups and downs. I asked the same question people VPN Firefox Add-ons. They said that he "may" impede the VPN. Laughing out loud. Nothing says confidence like the word 'power '! It doesn't seem to work perfectly. Here's what I think in very basic terms. The VPN uses encrypted tunnel of . Do Add-ons in fact drag these companies, they block, in the tunnel with the Firefox browser I use? Because the Add-ons are still show the number of companies they are blocked even if I'm in an encrypted tunnel . He looks like the tunnel needs block all businesses before that add-ons a chance to see them. And I have to start all VPN, tunnel, process on my desk before even entering the browser. I know I could start the browser with Add-ons disabled. I don't know if somehow they could work even n or if they work against each other. With or without the Add - ons Firefox remains my main browser! You guys and girls are great! Keep up the good work! Nice day.

    Firefox sends the exact same claims, but now, they go through the tunnel.

    Don't think that the VPN as a filter, think of it as a carrier.

    Instead of thinking of Web sites of your web requests from your home through your internet service provider, websites they will perceive as coming from the location of your VPN service using their internet service provider. If you visit sites that try to guess your location, you should see that they are now guess somewhere completely different. (If the sites stored cookies with your old location, then you probably still will see that.)

    With this in mind, it is logical that websites always pull in all the same ads and other things. To prevent that from happening, you will still need the modules.

    As to whether they will all work together perfectly, I don't know. Each user creates a unique mix, so there is probably no one in the world who can test it better that you can.

  • Read my version of Firefox Add - ons incorrectly

    I just upgraded to Version 7 of Firefox 3.0.11. I wanted to add some add-ons, but the Add-ons page won't let me download any of the new stuff because it says that I'm still in Version 3.0.11. To help title > tab on Firefox, it says that I am, indeed, Version 7.0 and that it's up-to-date.

    I tried to restart Firefox and even restart my computer. Also, I have re-downloaded Firefox Version 7. Nothing has worked.

    Your string UserAgent in Firefox is probably messed up by another program that you have installed, and it says that you run Firefox 3.0.11.

    type of topic: config in the URL bar and press ENTER.

    If you see the warning, you can confirm that you want to access this page.

  • Slower due to the Firefox Add-ons.

    This isn't a specific question, as this is more a general frustration with Firefox. I notice that Firefox is much faster if I turn off modules I have installed over the years. It seems that Firefox gets a bad wrap because some add-ons slow down Firefox. Are there no comparative analysis of the tools available to show before and after the results of the use of an add-on? I use 5 of 19 modules at the moment and the performance is much faster. All this time, I just thought that Firefox sucked while disabling modules leads me to believe that the person in charge of this slowdown is due to an add-on.

    In any case, I think that if Mozilla wants to protect their reputation more, comparative analysis tools should be a tool, a user can interact with.

    This thread is 12 months old. Mozilla has recently worked on this issue of modules.

    Test modules for startup, start with performance performance.

  • How does remove is - a 'In - Box '? (I was in Firefox "Add-ons" and FAQ without result).

    The 'Modules' of Firefox tab displays not the "In-Box" as an add-on.
    I couldn't find the solution in the associated articles.
    Please notify.
    Tom

    The Add-ons page is divided into several categories. As mentioned in ComputerWhiz, who is the most relevant is the category of Extensions.

    If you prefer to copy and paste rather than creating a screenshot, you can use the second big box on this page:

    Help > troubleshooting information

    It will look messy, but...

    In fact, the button-top "copy text to the Clipboard" - works fine.

  • I just downloaded the latest version of firefox, and apparently it was supposed to replace my old version, why can I still access the old version of my icon in the dock.

    I'm using mac os x version 10.7.4 and I try to update Firefox 3.5.5 version to the latest version. The Firefox icon in my doc still persists and leads me to the old version of Firefox. If it's supposed to happen?

    Some Firefox problems can be solved by performing a clean reinstall. This means that you remove Firefox program files, and then reinstall Firefox. Please follow these steps:

    Note: You can print these steps or consult them in another browser.

    1. Download the latest version of Firefox from http://www.mozilla.org office and save the installer to your computer.
    2. Once the download is complete, close all Firefox Windows (click on quit in the file menu or Firefox).
    3. Remove the Firefox installation folder, which is located in one of these locations, by default:
      • Windows:

        • C:\Program Files\Mozilla Firefox
        • C:\Program Files (x 86) \Mozilla Firefox
      • Mac: Delete Firefox in the Applications folder.
      • Linux: If you have installed Firefox with the distribution-based package manager, you must use the same way to uninstall: see Install Firefox on Linux. If you have downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
    4. Now, go ahead and reinstall Firefox:
      1. Double-click on the downloaded Setup file and go through the steps in the installation wizard.
      2. Once the wizard is completed, click to open Firefox directly after clicking the Finish button.

    Please report back to see if this helped you!

  • Facebook and Firefox does not recognize Firefox as my browser. Cannot install Firefox Add-ons.

    This all happened all of a sudden in itself. I have not installed new programs or software of any kind. I have Norton Security software, but it was installed on my PC for 6 months without any problem. I uninstalled Firefox3.6, 10. And reinstalled it, but this does not solve the problems.

  • Crash 24 Firefox Add - ons due to recent changes to the JSAPI

    We are facing problems with our modules support for FireFox 24. Firefox crashes. In the previous approach we was using 'JS_GetGlobalObject' to get the overall purpose of docShell.
    https://developer.Mozilla.org/en-us/docs/Mozilla/projects/SpiderMonkey/JSAPI_reference/JS_GetGlobalObject?redirectlocale=en-us & redirectslug = % 2FJSAPI_Reference % 2FJS_GetGlobalObject SpiderMonkey

    As per data link above - should I use use JS_GetGlobalForObject or JS_GetGlobalForScopeChain instead of JS_GetGlobalObject. I tried both of them and plus I tried GetNativeGlobal(), GetGlobalJSObject(). but none of them worked. Firefox crashes in all cases.

  • Update of the extension did not start more and why disappeared my (still works) add-ons/extensions in the add-it-manager?

    I use ff4 beta3 on a Win7 PC, this problem appeared in the beta 2 release.

    Some extensions still work very well: Adblock plus, NoScript,.

    Others appear in the menu of the hull, but aimless: video download helper, Ubiquity (a small rectangle behind the arrow in the menu right-click) and no longer work.

    Updated extensions via the button in the gui management either dosen't work.

    This problem is permanent. I don't think that there is a problem with some extension, but I could be wrong. I had installed about 30 extensions, many have been disabled.

    Thank you very much

    Andi

    Beta 4 is already available (24 August): http://www.mozilla.com/en-US/firefox/all-beta.html

    Beta 5 will probably be released next week: https://wiki.mozilla.org/Releases/Firefox_4.0b5

    You can delete the files (extensions.sqlite, extensions.rdf, extensions.cache, extensions.ini) extensions.* and compatibility.ini in the Firefox profile folder to reset the extensions registry. New files will be created if necessary.

    See "extension corrupted files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions

    If you see disabled extensions are not compatible on the next departure in "tools > Modules > Extensions" and then click "Find updates" to do a compatibility check.
