I just got a new Dell Windows 11 desktop PC to replace my old Dell Windows 10 PC. Since switching, there are three sites that will absolutely not load the homepage: Paypal, Venmo, and Common Dreams (which is a news site). The same sites continue to load instantly on my old Windows 10 PC in Firefox, and on the new Windows 11 PC on Edge. Firefox is the only browser I use, I just use Edge to test sites, I uninstalled Chrome because of Google's privacy and AI issues.

In the lower left corner of the window for these three sites are the following messages, for the three respective sites:

• Waiting for www.paypalobjects.com...

• Sending request to jssdks.mparticle.com...

• Waiting for www.commondreams.org...

What's going on here? Seems strange that Firefox continues to behave normally on Windows 11 for all sites except these three, and works perfectly for these three sites on my Windows 10 PC. How can I further troubleshoot and fix this? I don't want to have to use Edge to visit these three sites, esp. Paypal and Venmo.

I'm guessing it has something to do with cache or history but am not sure how to proceed...

I am using Windows 11 on a Dell laptop. I have the latest version of Firefox installed. I have used Firefox as my default browser on this machine and O/S for the last year with no problems. I can use Firefox to get to other websites without issue, using either a 5G cellular connection or a WiFi connection direct from the Dell laptop. I DO NOT use password vaults or any kind of automated password entry, and I do not have any bio-metric access functions activated on the laptop; I enter usernames and passwords manually, as needed. I have accessed my Outlook Hotmail account using Firefox without problem up until about 4 weeks ago. Now, I can enter my username successfully, but when I then enter my password I get a rejection screen response from Microsoft (clicking on it, I then get a "help" screen about what to do after getting a 404 message). After navigating through a maze of screens from Microsoft I will get an opportunity to verify my identity by using my cell phone and entering a 6-digit code (essentially a form of "2 factor" identification) and then I will get access to Outlook on the Firefox browser. I should mention here, that I don't use 2 factor ID on my email or with Outlook, and after entering my password, I would have been connected to my email directly. I do NOT have this issue when I try logging in to Outlook using Chrome or Edge on the same machine. I have: rebooted my machine, reinstalled the latest version of Firefox, cleared cache, used Firefox in Safe Mode, cleared cookies and browser history, turned off tracking protection, cleared URLs from tracking protection exceptions, and tried various combinations of all of the above. I also ran "scannow" and "DISM" functions to make sure Windows is not corrupted. Nothing has fixed the problem, and, Microsoft Support claims that since the other browsers work, the problem must originate with Firefox (surprise, surprise! ...). Any assistance in what steps to take to get Outlook to accept passwords that are sent through Firefox would be greatly appreciated!

Every day, I get the same reminders about new Firefox features. Every day, there's one about tab groups. I get daily reminders to sync my bookmarks. I do not need this every single day.

How do we turn off the reminders? Why do they not stop appearing after an update, the way they normally do?

Thanks!

Since I upgraded from FF128-esr to FF140-esr I always get the "Firefox is being updated by another instance" This is really driving me crazy, as I checked / did / .... everything (and even more) I found on the internet related to that.

Nothing helps !

Creating and using a new default profile didn't help

Finally I ended up uninstalling FF completely (making sure no -zero- leftovers remained in ProgramFiles, AppData a.s.o.), and reinstalled FF140.7.0-esr freshly. After installation I started FF immediately with the created default profile (only existing one) --> SAME THING : "Firefox is being updated by another instance"

And this is really a FF140 thing, when I go back to FF128, on the same computer, same profiles, ...., the problem is gone.

I would like to know in detail what checks are really done by FF to decide to give that "Firefox is being updated by another instance"

Firefox 147.0.4 on macOS 26.3 does not work via SOCKS proxy.

Firefox 147.0.4 on Windows 11 x64 works fine via the same intranet SOCKS proxy, with exactly the same settings.

The advantage of Firefox is its flexibility. It supports its own SOCKS proxy settings, independent of systems-wide ones. Unfortunately, it seems this Firefox feature is broken on macOS (but Windows version works perfectly).

Safari 26.3 (21623.2.7.11.6) and DuckDuckGo 1.177.0 (625) web-browsers that use system-wide macOS SOCKS proxy settings also works fine with this intranet proxy server. So it seems SOCKS proxy server itself is OK, and the problem is confined to Firefox on macOS.

Has anyone seen Firefox 147 on macOS work via SOCKS proxy? Is there a principal difference between how Firefox handles SOCKS proxy on macOS vs. Windows? What might be the best way to address the problem on macOS?

Thanks!

I am only able to shut off these new tones Firefox makes in Windows 11 Volume control center by muting Firefox. Then if I do, I am forced to return to that button to unmute if I want to listen to a YouTube video etc.

I've never had this issue with Firefox until 2026. I'd like to find a setting within the Firefox Settings, but there is nothing. No other browser does this. Only Firefix.

It's annoying. I'm going to have to start putting Firefox aside and stop using it. It's too much of a nuisance.

Firefox has no customer support. Only a Community Forum. So, I don't think they'll miss me.

After the most recent upgrades (both MacOS to 26.4 beta and Firefox 147.0.4), Firefox is giving me this message: Hmm. We’re having trouble finding that site. Any suggestions?

I cannot find how to add a New Bookmark to an existing bookmark folder from the screen when I am visiting a Website I wish to Bookmark. Should be simple, but I cannot find out how to do it. There is no simple drop down menu that says ADD BOOKMARK and give you a choice of what folder to save it in. HELP !!!!!!!!
