I can't install add-ons; get "connection failed"
My add-ons disappeared suddenly and I can't install new ones. I get "Download failed. Please check your connection." My connection is fine.
I've tried disabling my anti-virus, getting off VPN, getting back on VPN, starting FF in safe mode -- nothing's working. I installed 66.0.3 on April 12 and everything was fine until tonight. What can I do to get my add-ons back?
Additional System Details
- Shockwave Flash 32.0 r0
- User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:66.0) Gecko/20100101 Firefox/66.0
This issue is currently being worked. We apologize for any inconvenience this has caused. https://discourse.mozilla.org/t/certificate-issue-causing-add-ons-to-be-disabled-or-fail-to-install/39047
Work around :
1) Right - Click on install add-on button. 2) Save add-on as file : file should have xpi extension. 3) Go to the add-on fire fox menu. 4) Click on gear looking icon. 5) Click on DEBUG add-on. 6) This will load add-on.
Addition: 5.1) After clicking DEBUG click on "Load Temporary Add-on..." 5.2) Select downloaded file. (should have xpi extension)
Mozilla has rolled-out a fix for this. 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, they are using the Studies system. You can check if you have studies enabled
- Go to [=] > Options > Privacy & Security.
- Make sure Allow Firefox to install and run studies is check marked.
I you had it disabled, you can disable studies again after your add-ons have been re-enabled.
They are working on a general fix that doesn't need to rely on this and will keep you updated.
I turned on Studies ... no change. Also checked about:studies.
Is this temporary fix working for others yet?
Update: I thought "no action needed" meant no action needed if "Studies" was enabled.
Instead, I tried installing a new version of one add-on and that worked. So if someone is finding that the fix isn't being applied, try installing the add-on.
There was a Bug-A-Boo with a Certificate Expiration Date dealing with the Add-ons. There's a new FF Version with the main Fix, 66.0.4.
Mozilla Blog Post Update:
A Firefox release has been pushed — version 66.0.4 on Desktop and Android, and version 60.6.2 for ESR. This release repairs the certificate chain to re-enable web extensions, themes, search engines, and language packs that had been disabled (Bug 1549061).
There are remaining issues that we are actively working to resolve, but we wanted to get this fix out before Monday to lessen the impact of disabled add-ons before the start of the week. More information about the remaining issues can be found by clicking on the links to the release notes above.
