Hi. Strange request I know because Firefox is working perfectly but Google has failed me.

We have a printer/copier in our small club. The IP address assigned is 192.168.1.125. Typing this into a browser should bring up the copier admin dashboard.

When I do this using Firefox everything works fine, BUT when I use any other browser such as Chrome, Edge or Opera I get the "Cannot connect" "Error connecting" etc message.

I removed Bitdefender antivirus and disabled Windows Defender but it's still the same.

Any network people who can point me in the right place as to where to look or report to the correct forum.

Apologies for posting in here when it's not a FF problem.

Thanks in advance TQO

My Firefox can only be shut down by TaskManager, or by clicking on the three horizontal bars and then dropping to exit.

So I can't close any single tab 'without closing them all', that's the real annoyance. I also can't close any individual windows I opened instead of a new tab, without closing all tabs and windows. Finally the classic windows ALT+F4 closure that's built into Windows doesn't close Firefox, and if it did I suspect ALT+F4 would close them all. Bottom line Firefox is seriously close-resistant.

What precipitated this was I allowed a previous Firefox update to download-install, and it tanked my performance, I figured your team would fix that issue, but in the meantime what I did was uninstall that version and reinstall the version I had been running before that update. Tilt! That action resulted in the close windows or tabs problem.

Summary: I am using the latest version now, but with it came this "can't close any individual tab without closing them all, and can only close even then except by Taskmanager or by clicking the 3 horizontal bars then dropping to Exit which also closes all Firefox tabs and Windows. This problem has surfaced before in this support, and none of the solutions worked, probably because I got to this place uniquely. I did read before submitting this.

Hello, I'm using samsung odyssey g7 32' monitor connected to my laptop with a rtx 2060. The monitor is connected with a minidisplay port to display port cable. The problem doesn't occur on the laptop screen but it does on the samsung screen. The flickering stops when i make the window a little smaller. I am using KDE plasma 6.0.3 but the problem was also present when i was using Hyprland as my desktop enviroment. I tried troubleshoot mode but nothing changed. I am seeking help. Thanks.

I sent an email to the support email given for this add-on but didn't get a response, so maybe others can help:

I'm using the 'Simple Tab Groups' add-on on my Mac computer and am happy with it but I have one question. When I click on a web link in an email (I use the native Apple Mail), it of course takes me to my default browser which is Firefox, and then within Firefox to the simple tab group that I had open in Firefox before clicking the link. Logically I guess that's reasonable behavior but typically that's not necessarily what I want; I'd rather it open the web page in my 'main' tab group.

Is there a configuration option to say: "When clicking on a web link in an email, open to this xxxxxx default tab group"?

I cannot remove "Your browser is being managed by your organisation" and seems to be stopping the home settings saving. They simply revert back to the default (see image) when I restart Firefox. Not sure what is meant by "your organisation" as I am a personal user, not organisation. I'm the single user of the browser (e.g. just one user on my PC, which is me) and also Admisitrator. Can someone help me remove this. Thanks John

Sometimes all add-ons / extensions break randomly and are disabled (the icon of the extensions is also broken under "Manage Your Extensions").

The extensions are visible under "about:addons", but the slider is turned off and the icon in front of each extension is broken / empty.

It seems that deleting these 2 files- compatibility.ini and extensions.json inside the firefox profile folder, usually fixes the issue. Only these 2 files though, don't delete anything else.

No need to mess around with the ff profiles or anything else, just deleting those 2 files and restarting the firefox usually fixes the issue with the "unregistered" addons.

This thread is for the search function, as I found some VERY old and outdated suggestions for the aforementioned issue using the search function.

I wonder what causes the extensions to "unregister" randomly.

Hey all, as of the past few days when I get the prompt to enter my password on Outlook.com (And microsoft.com) and hit 'sign in' the page just reloads and nothing happens. There is no failed login message, the page just reloads like I didn't hit sign in. I have disabled all of my extensions, cleared cookies and cache, ETP... with no luck.

Works fine on Chrome for android...

I'd really like to stay with Firefox so all help seriously appreciated

Whenever I select tab and then start typing in the page search box it automatically jumps to the URL/Address bar. This is not only annoying but it makes it difficult for me to see what I'm typing, and it often results in unwanted typing errors. I have yet to encounter a single longtime Firefox user who thinks this is a good idea, but I have met several who've decided to drop Firefox and start using Chrome just to be done with it. I've been using Firefox since early 2005 and I've mostly been happy with it but this is just to annoying to continue. I'm complaining because the feature exits, I'm complaining because there's no option to opt for those of us who find it annoying and will never become comfortable with it.

If there is a working fix that I've been unable to find, then please point me to where or what it is so that I can apply it.
