When attempting to access gmail on my new (2023) iMac running Sonoma 14.5, Firefox 115.12.0esr freezes and must be force-quit. I've seen similar issues on this and the Apple forum, but not this particular problem. Any suggestions? Thank you.

Hello everyone,

I have a problem. I have seen that there have been discussions about this in the past. Unfortunately I have not found a solution and the discussions are all archived.

Now to the problem: Various pages have no favicon in Firefox when I drag them into the bookmark bar as a bookmark. However, when the page is active in the tab, a favicon is visible there.

The problem does not seem to be unique to me. Several people have tested it. It also seems to be a problem in Firefox only. In other browsers, this problem does not occur.

What can website owners do to fix this problem?

Here is an example of a site where I have the problem. www.organspende-register.de

Many thanks in advance. Best regards

I can open links in tabs and those can be foreground or background but I cannot find a way to open a link in a new private window that doesn't require the context menu. Does it not exist?

I don't want to use passkeys, and it seems that every site is checking browser support and wasting my time with passkey prompts before allowing me to log in with a password. How do I disable passkey support in Firefox?

I can no longer use Duolingo (macOS Monterey 12.7.5) because the pages get stuck loading. I've cleared the cache and cookies for it and it still doesn't work. In addition, I've submitted multiple bug reports to Duolingo. Apparently the developers there pay zero attention to these. I want to use Duolingo on my iMac and I love using Firefox as my browser. WHAT is the problem and how can I fix it???

Hello,

I just found out I cannot longer drag an icon from the search bar to the my bookmark toolbar. I loved this feature because it would let me organize my bookmarks with just icons, and have them readily available. But now, I can't do it, not even dragging the URL across the toolbar! Why? Is there a way to fix this? Any help would be greatly appreciated!

I am using Firefox version 126.0.1 (64-bit) on MacOS Ventura 13.0. I cannot interact with any Nature journal webpages (https://www.nature.com/ , https://www.nature.com/neuro/ , etc). I can only scroll, no clicking on links, highlighting or anything else you might expect. Not sure if this is specific to my computer/browser/extensions or if others are experiencing this and what steps I might take to resolve?

I have noticed a few websites will go to blank pages. Today, while trying to log into my Microsoft account, I was able to enter the login id and then the password, but when I went to enter the website I arrived at a blank page. I tried the control-shift-R fix, from this website, but it was of no value.

Firefox 126.0.1 displays a very long name of a container completely in the URL bar.

Firefox 127.0 truncates container names

AWS long account and role names make keeping the long name very convenient (works with the 'AWS SSO Containers' Add-On

When I try to login to my Social Security account after pulling up the Soc Sec site (ssa.gov), I get this message:

"Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit."

I tried waiting a couple of days and attempting a login again. I also tried turning off my VPN, using a new tab, refreshing the site and restarting my laptop. I do not get this message when I use Safari to login, but I want to use Firefox.

Thanks for your help in fixing this problem.
