Did Firefox disable yesterday about one-third of the extensions?

At least that's how many of my add-ons were disabled. Some of them are from highly "suspicious" developers, such as, Capital One, Rakuten and American Airlines, so I can see why.

I tried reinstalling one and it wouldn't work.

I see now that this was probably a glitch. But, as FF says, if "extensions are apps for your browser", what would happen to Google if it disabled one-third of the Play Store?

Late on Friday May 3rd, we became aware of an issue with Firefox that prevented existing and new add-ons from running or being installed. We are very sorry for the inconvenience caused to people who use Firefox.

We rolled-out a fix for release, beta and nightly users on Desktop. The fix will be automatically applied in the background within the next few hours, you don’t need to take active steps.

In order to be able to provide this fix on short notice, we are using the Studies system. You can check if you have studies enabled as follows:

  1. Click the menu Fx57Menu button at the top right of the Firefox window.
  2. Click on Options (Windows) or Preferences (Mac and Linux).
  3. Select the Privacy & Security panel and scroll down to the Firefox Data Collection and Use section.
  4. The box next to Allow Firefox to install and run studies should be checked.
    • If the box is not checked, click it to check mark the setting.

You can disable studies again, if you wish, after your add-ons have been re-enabled. See About Studies for more information.

Please do not delete your add-ons as an attempt to fix. You will lose any data related to the add-on. Disabled add-ons will not lose any data.

There are a number of work-arounds being discussed in the community. These are not recommended as they may conflict with fixes we are deploying. We’ll let you know when further updates are available that we recommend, and appreciate your patience.

There is no fix available for Android at this time. The team is working on it.

Thanks, I saw that. One thing that doesn't say is which versions support "Studies". I don't have it on mine.

I find it curious that reinstalling an add-on (where presumably I lost the data on it) does not work. It's as if it's being blocked.

In any event, was this human error or a technical glitch? I think people would like to know who and what manages their browser and data.
