All my addons disappeared and I can't download new ones
Last night, I found out that all of my add-ons have been deleted except Nuke Anything. When I tried to re-download some of the add-ons that I lost, I received this message: "Download failed. Please check your connection." Assuming it meant my WiFi, I did. My WiFi is fine, but I was still very confused. After checking the support forums, several others had a similar problem, but theirs was related to study: hotfix-reset-xpi-verification-timestamp-1548973 . Here are some of the add-ons that I lost: Vivaldi Firefox, uBlock Origin, LeechBlock NG, Better OneTab, Privacy Badger, Dark Mode, and Youtube Enhancer. There may be others, but those are the ones I remember. After checking my about:preferences, I find that not only did that study not exist in my past studies, but the option to allow Firefox to run studies on my account has been disabled.

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. See Add-ons disabled or fail to install on Firefox for more information.
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:
- Click the menu
button at the top right of the Firefox window.
- Click on Options (Windows) or Preferences (Mac and Linux).
- Select the Privacy & Security panel and scroll down to the Firefox Data Collection and Use section.
- 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.
- 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.
