My issue (https://support.mozilla.org/en-US/questions/1258165?page=1) was closed before I could respond! So, I am following up here.... (and I could post this follow up there -if you want to re-open that thread, for continuity of the issue?)
I tried your solution to update the certificate, but it did not work.
Note, I could not figure out where to check the certificate was updated (as you posted in the screen capture of image #2).
The first step seemed to work (clicking on your link and clicking OK on the popup to download the certificate).
The RESET of the lastupdate value also seemed to work, and after restarting Firefox it now shows VALUE of 1557118303.
But the adblcok plus stll not working.
Note, I tried to download the certificate using step 1 again, and that time an ALERT said CERTIFACATE ALREADY INSTALLED...
What can I do now?
FYI: Your instruction in the OTHER THREAD was:
Hi Matt, I was able to start testing in Firefox 52 ESR. When I install the hotfix extension, nothing happens, other than showing up on the Extensions panel of the Add-ons page. In the Browser Console, I see this message: TypeError: browser.experiments is undefined That means the main command of the extension doesn't run, so it's a dead end.
(1) Install the certificate the hotfix would have installed (2) Trigger Firefox to re-verify your extensions (3) Wait until it is back to normal
(1) Install certificate
I extracted the certificate from my Firefox 66 and saved it on my webserver. Obviously if you don't trust me, you should not install it.
Two possible methods: click to download through the certificate installer, or right-click > Save Link As to save a local copy and then import it.
Screenshot #1 shows the download method. Don't check any of the boxes, just click OK.
To import instead:
Go to the Options/Preferences page, Advanced section, Certificates panel, then click Certificate Manager. Make sure the Authorities tab is selected, then click Import. Find the file you downloaded and open it, then you should get the same dialog as in Screenshot #1, don't check any of the boxes, just click OK. Then you should see the new cert in the list in the Certificate Manager, as shown in Screenshot #2.
(2) Clear the time Firefox last re-verified
This will set Firefox up to check much sooner than it otherwise would check.
(A) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful or accepting the risk.
(B) In the search box above the list, type or paste xpi- and pause while the list is filtered
(C) Right-click the app.update.lastUpdateTime.xpi-signature-verification preference and click Reset on the context menu
Screenshot #3 illustrates the expected result.
(3) Restart Firefox
You can exit Firefox normally, then start it up again. In my tests, it took less than 60 seconds for Firefox to verify my extensions. Screenshot #4 is "before" and Screenshot #5 is "after."
Hopefully that will work for you.
