Firefox 社群討論區

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 !!!!!!!!

On macOS, I set System Settings -> Desktop & Dock -> "Double-click a window's title bar" to "Fill".

In Firefox, double-clicking the window title bar does nothing. If I change the macOS setting to "Zoom", double-click works correctly in Firefox doing Zoom effect.

I confirmed that other applications respond correctly to the "Fill" setting.

Environment: - macOS version: 26.3 - Firefox version: 147.0.4 (aarch64)

for about 8 years now, on and off, on hundreds of OS-es, clean installs of firefox etc. sometimes - not always - typing into the firefox search bar and pressing enter does nothing

i have bit-warden, u-block-origin and stylus installed (but they shouldn't be running on the 'new-tab-page' - is my firefox sync-profile containing some firefox-breaking-errors? (latest Win-11)

On outlook.com sign in with password does not work. It gives "Please retry with a different device or other authentication method to sign in." Works fine in edge.

I just had a firefox tab with a pop up asking me to try ai features... my options were "yes" or "maybe later". How do I stop the slop sales? I want ZERO pop ups... from Mozilla or anyone else! I didnt see settings that would disable mozilla sales pop ups - is there some way to turn these off permanently? I have already turned off the ai features. Really appreciate any suggestions!

Spectrum recently updated their email systems and Firefox can no longer be used to check Spectrum webmail email accounts. I used to be able to go directly to the webmail but now they make you log into your Spectrum account to get to the email accounts and there is something about Firefox that is not up to their security standards. I am running Windows 7 with the latest Firefox that will work in 7. I am also running the Brave browser on Windows 7 and that works with the new Spectrum system. I prefer using Firefox over Brave so could you please correct whatever deficiency exists in Firefox to make it compatible with Spectrum webmail?

FYI, Firefox on my Windows 10 machine has the same issue.

Error Message: We're sorry, something didn't work quite right. Please try again from home or contact us for assistance. IDID-4049.

Thank You
