Whenever I shop online, when I start to input my credit card number at checkout, the last 4 digits of every credit card I've ever used comes up in Autofill. All I have to do is select one, then select its exp date, and it fills in the slots automatically. I find this very convenient, and I trust that it's secure as long as the site itself is. BUT by now, several of the cards that come up have either expired or are no longer in use. HOW DO I DELETE THEM FROM FIREFOX' AUTOFILL LIST? Please help--I've been unable to find the answer to this Q, though I've thoroughly searched. I'm losing patience. I don't want a lot of unused/expired cards on your Autofill. Thank you!

I need to udate my current version of Firefox, however, my MAC is so old that it wont run the most currnet version of Firefox. Can anyone tell me which version will run on my MAC Sierra version 10.12.6 Thank you.

I have downloaded Firefox ESR and think it has been installed on my masOS version 10.12.1 and am wondering if I can use it on this version after reading your warning about support. Perhaps I have not installed it properly as I have just used what I think was the previous version since it has all the oldsaved sites.

For some reason, though I have changed absolutely nothing with my browser, now any time a link is supposed to open automatically in a new tab, it opens in an entire new window. My mouse only has two buttons (Magic Mouse on Mac), so there is no way at all for this to be user error in that regard. The best example is in Gmail when you have multiple accounts signed in, you click the profile picture in the upper right and select a different account which then opens in a new tab. I notice that when I use a fresh profile the issue goes away, and migrating a copy of my existing profile between different Firefox versions (this profile I use in 115 ESR exclusively, I don't use it with more than one version, I just mean for testing purposes here), including forks like Waterfox, all are affected by this issue. Is there something in about:config I should look for to change?
