The main issue people may encounter with Firefox 48.0 is with using older Extensions that have not been signed.

Make sure you have the latest versions of the extensions. https://addons.mozilla.org/firefox/addon/noscript/versions/ https://addons.mozilla.org/firefox/addon/ghostery/versions/ https://addons.mozilla.org/firefox/addon/https-everywhere/versions/

The support forum for NoScript at https://forums.informaction.com shows no indication that Firefox 48.0 including the official builds from Mozilla.org/firefox/all/ is breaking NoScript.

However on Fx48 Noscript may block any rss feeds you have unless you allow the feed's parent site in NoScript.

I have my extensions on automatic update so this shouldn't be an issue. I assume noscript was itself in the noscript whitelist since I have gotten their upgrades in the past.

I cannot even uninstall noscript. It simply sits there when I try.

I did notice an error message when invoking firefox from the command line. Perhaps someone can interpret it for me:

OK I went to check and noscript is at 2.9.0.4 which is not the most recent, 2.9.0.14. I don't know why these stopped updating; again it is set for them to automatically update. Anyway now I am stuck and I don't know how to proceed.

For what it's worth, when I try checking for updates, these errors come out at the command line:

When I look at the "staged" directory it lists as follows: drwx------ 2 root root 4096 Mar 18 20:41 staged

Inside the "staged" directory it has this: drwx------ 2 root root 4096 Mar 18 20:41 . drwxrwxr-x 5 paul paul 4096 Mar 18 20:41 .. -rw-r--r-- 1 root root 4803 Mar 18 20:41 {73a6fe31-595d-460b-a920-fcc0f8843232}.json -rw------- 1 root root 562656 Mar 18 20:41 {73a6fe31-595d-460b-a920-fcc0f8843232}.xpi

It's odd these are owned by root:root, is that normal? Seems like it should be paul:paul, like the rest. I wonder how they got changed.

I changed the ownership of these files and now the updates happen.
