I tried to reproduce this issue with Firefox 57.0b12 on macOS with,, and master, and in all three cases it worked fine.

Ross, could you try again with the latest build and, if possible, on both macOS and Windows?

Ross mentioned already that this doesn't seem to be reproducible reliably. Also, I have a strong suspicion that this is a Windows-only issue like #5817. At least I wasn't able to reproduce on Linux.

windows tests FF 57, ABP

  1. click subscribe a list (on this page)
  2. options page is opened, no confirmation dialogue
  3. stay on options page and click again the subscribing link ==> now the confirmation dialogue is opened.
  4. if I click again subscribing for the same list => the addon does not warning the list is already subscribed.

However, I get no error in console.

Reproduced steps mapx has added. If the options page is not already open, the dialog does not appear. If the options page is already open it does. There is also no warning about adding a duplicate subscriptions.

I've also noticed that the subscription is added before the confirmation dialog is answered, and if the user chooses "no" (via the top right X) the subscription is still present.

ABP 3.0.1

While I am still unable to reproduce this issue using these steps, I'm fairly certain that it is the same issue as in #5817 - the message sent to the options page arrives before the page is ready. So it's not a UI issue but rather still Platform.

comment:11 Changed 2 weeks ago by trev

Actually - no, the code seems to wait for the page to be ready already.

I've not been able to reproduce this on Debian Buster with Firefox 57.0b9, I'll have a try with Windows 10 when I get a chance.

comment:13 Changed 13 days ago by kzar

I can reproduce this with Alockplus 3.0.1 on Firefox 57.0 and Windows 10.

Going to stop soon but I'll investigate further next week.

comment:15 Changed 12 days ago by kzar

The message responder for "subscriptions.add" calls showOptions, but the callback for showOptions is not being made. It seems that's because findOptionsTab in lib/options.js is returning undefined, despite searching for the correct URL for the options page.

It seems this is because the tab Object that browser.tabs.query is returning for the options page has a url of "about:blank" (but a title containing the URL we were expecting). I'll attached a screenshot to show what I mean.
