Unable to install any addon

Hi.

Basically, I cannot install any addon. When I hit "Add to Firefox", a popup showing permissions appears, but the "add" and "cancel" does not work at all.

I tried downloading the xpi file and installing by opening it or clicking "Install add-on from file" in the Add-On manager but to no avail.

I also don't remember when I first got the problem. Maybe it was after updating to a newer version. I hesitated in asking for support, because it's such a pain to have to migrate everything manually. I used to use FEBE before. If there's no way for an easy migration to a new profile or easy fix, I rather stay as it is.

Thank you.

Possibly just a single file has become locked or corrupted; you may not need to do much more than remove that file and let Firefox regenerate it. Unfortunately, there's no way to know without trying.

Before getting into that:

(1) Does your current profile contain any files copied from other profiles?

(2) Does the Add-ons page, Extensions panel, work normally or is that broken in some way(s) as well?

Thank you for replying.

1. The only file I copied from another profile is the "userChrome.css" inside the chrome folder.

2. The Add-On page work just fine. I can change addons settings, activate/deactivate them. Themes too.

Hi agent666,

We're very sorry for the inconvenience here.

There has been a technical issue with Add-ons that the Firefox team is working on urgently (it affects in the installation of new add-ons and usage of installed add-ons). You can expect a resolution soon.

Sorry again, George

Hi geroter,

Thanks but the recent issue is not related to my problem. At least, mine's dated back for about 2 to 4 months ago.
