Firefox Community Forum

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.

Chase Bank says I can't view my accounts online because I need to upgrade to Firefox 128 or higher. How do I do this so they can support this information on my MAC computer

I'm trying to log into Peacock tv and i'm getting a message that my browser is not supported. It was working for months and I'm suddently getting this error message.

Your system has now blocked me from accessing Jacquie Larson e-card site to receive or send e-cards. Today it blocked me from opening my statement from Edward Jones. Both of these are sites I have used for years and do not pose a threat to my computer. How do I get rid of this aggressive blocking and get back to reaching these websites?

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?
