Updated Firefox

[midnight]

to the latest version and I no longer have any extensions, no avast online security, no plugins and when I search for extensions it shows loading but it doesn't do anything.  How can I get the Avast Online Security extension?

hi midnight,

You've got firefox version 46.0?  If you did a clean install of Firefox could be the way you lost your extensions, plugins, and AOS.  Please recall that AOS needs to be digitally signed for Firefox to run it; if it is an older version Firefox will not run it.  You've still got all your bookmarks in place?

Finally, did you do a disk image before you updated Firefox?

I updated to firefox 46.0 from the Help - About Firefox option on both systems and add-ons remain as they were prior to the update.

The avast AOS add-on has been digitally signed (a couple of FF updates ago) as far as I'm aware.

@DavidR,

That's the way I updated and up until yesterday it showed all of my add-ons after updating.  Rebooted my computer, checked the add-ons and they were all there.

Thanks for letting us know.  Mayhaps one may need to reboot system to get the old add-ons to show again after an update from now on?

Here is the full offline executable to update as here:  https://www.mozilla.org/en-US/firefox/all/

I didn't have to reboot to see all of the add-ons, I just did as Firefox said, restart Firefox.

Not signed perhaps ?
I think it was around this FF version number that unsigned add-ons were finally going to be blocked. As had been mooted from around FF 42.0 version.

Firefox add-on signing is enforced in Firefox 46 on the Stable or Beta channels but not mandatory. Mozilla plans to make it mandatory with the release of Firefox 47.
If you are using Firefox 46.0, in about:config toggle preference 'xpinstall.signatures.required'

I already have that user set to false in preparation, but even that option to change the about:config is also going to be killed off as far as I'm aware.

it doesnt work because it uses javascript array comprehension for hash calculation. it is a mass image saver addon called Bazzacuda. I view and download alot of images from currently open tabs, but sadly there are no alternate addons i can find anywhere.
