Not able to install noscript

[Jeanette]

Hi!

I've tried 6 times to install Noscript with no luck. I allowed the "noscript.net" page, I set the value to true in "about:config" and it still doesn't work. I'm not getting an error message or anything, it just says that I have to restart firefox to complete the installation, and when I do, nothing happens. Firefox just won't install it. My virus program is also not blocking it, so I have no idea why it doesn't work.

Where are you getting NoScript from?
What value did you set to "true"?
After you restart, what are you expecting to happen?

Does Error Console show any related messages?

I have a similar problem. I just recently installed Win7 64 bit and Firefox 3.5.4 and can't install noscript. When I try to do that, I get the error: "Firefox could not install the file at: https://addons.mozilla.org/en-US/firefo ... ddondetail". I can install it in the Win7 XPMode Firefox just fine. So it seems to be related to 64bit Win7 somehow. Any help? Thanks.

I got it from this page: http://noscript.net/faq

What value did you set to "true"?

I did what it said in this guide:

"If Firefox still refuses to install the xpi,

1. Open about:config in your address bar (like it was a normal web site address)
2. Find the xpinstall.enabled preference and set it to true
3. Retry installation"

After you restart, what are you expecting to happen?

Well, I expect the installation to be complete, like it says right before I restart. When I open firefox again, I'm supposed to have the addon installed, but it 's not.

Does Error Console show any related messages?

No, I don't get any error message.

Hi, Jeanette. Try installing it from the Mozilla add-ons site instead. https://addons.mozilla.org/en-US/firefox/addon/722

Edit: If NoScript still doesn't install, then It sounds like one or more of your Add-Ons Manager files is corrupted. Could you try to follow the steps outlined in this article?

Allen Baxter-Thanks!!!!!!! It worked for me. By deleting the extensions.ini, extensions.cache, and extensions.rdf files Firefox recreated them and No Script works great. Thanks again - you are a marvel.

Great, Stan. Thank you for letting me know. I hope it works for Jeanette too.

Perhaps this will help someone in a similar situation: if your NoScript just won't install due to signing errors, just download the .xpi and remove the zigbert.* files from it.

I have been using mostly the same non-default Firefox profile for some time. Since it is extensively customized I've been unwilling to whack it and create a new one. However I have noticed that, for some time (approximately the 3.5 era?) I've been able to update the extensions in my default profile but not in my most-used profile. As a result, e.g., that profile's NoScript was stuck @ version=1.9.5 for awhile.

I tried the usual suggestions (delete the profile_directory/extensions.* files (but not the profile_directory/extensions/ directory), twiddle about:config, etc) but nothing worked. Eventually I deleted and reinstalled my other extensions (other than NoScript--more below), and they're now up-to-date. (They also kept their configurations, which was nice: I backed up the profile_directory/extensions/ directory but would not have wanted to figure out what files to copy.)

This worked fine for all my extensions except NoScript, which stubbornly refused to install due to signing errors, even when I downloaded the .xpi and drag-dropped into the Extensions Manager. Figuring there had to be some kinda certificate in the .xpi, I opened noscript-1.9.9.14.xpi in emacs, which has transparent zip support. I noticed

-rw-rw-rw- 1935 28-Oct-2009 00:53:00 META-INF/zigbert.rsa

referred (internally) to a certifier (usertrust.com), so I deleted both zigbert.rsa and

-rw-rw-rw- 1538 28-Oct-2009 00:53:00 META-INF/zigbert.sf

from the .xpi. I was then able to install NoScript by drag-drop-ing the modified .xpi into the Extensions Manager.
