Firefox-Hilfeforum

I'm using Firefox 124.0.2 (64 bit) on Windows, and every few days I get the error about using an older version of Firefox, with Exit or Create New Profile options. I then run "firefox -allow-downgrade" from the command prompt and everything works fine... for a few days, when it happens all over again. This only started happening a couple of weeks ago, but it's getting really annoying. How do I stop it (short of using something like Waterfox or Brave).

I reset a computer, deleting all my files. I want to use, as I do elsewhere, Firefox as my browser. And though I signed into Firefox using my old credentials, none of my bookmarks are there. How do I complete this setup?

So I'm having issues playing 4K videos fully on one YouTube channel: https://www.youtube.com/@ClearviewDriving

For some reason anything above 1080p gives me bad stuttering but on other channels videos don't stutter or freeze when playing 1440p or 4K quality.

Firefox is updated, I don't use Extensions other than Ad Blocker and I have that off on YouTube anyway. Seems strange that it'd only affect one specific channel.

I have a very good gaming PC too so the hardware isn't the issue.

My laptop lost power mid-session and since then Firefox hangs after opening and becomes unresponsive. Can’t do anything on it. Troubleshoot mode does the same. Booted up my computer in safe mode, no change.

I’m guessing a reinstall would fix it but I had a bunch of tabs open that I’m really trying not to lose. And I didn’t have an account to save them, I’ll rectify that after this.

I've recently started using the Tree Style Tab extension, and I'm finding it useful, but I'd like it if the list of tabs could be automatically hidden when only one tab is open (and automatically shown when more than one tab is open).

I hoped to write an extension to do this, but opening the sidebar from an extension requires a user gesture, so I suspect I'll have to use a userchrome.js script.

From a "userchrome.js"-like environment (i.e. unsandboxed AutoConfig), I can hide and show the sidebar with `SidebarUI.hide()` and `SidebarUI.show("treestyletab_piro_sakura_ne_jp-sidebar-action")`, and I can examine the tabs open in the current window via `gBrowser.tabs`, but I can't see how to get notified when the number of tabs changes (replacing `gBrowser.tabs` with a proxy doesn't work, for example). I suppose I could just check every few seconds? That feels like a bit of a cop-out, though, and gets more and more inefficient the more windows are open.

There's an API for extensions to receive events when tabs open and close, so clearly this is possible. Where should I be looking for this functionality?

(I also don't know how I would go about unregistering an event listener (or cancelling a setInterval call!) when the window closes, assuming that's necessary to avoid leaking resources – is there an event like `chrome-document-global-created` I could listen for, but that fires during teardown of the window rather than when one is created?)

How do I turn off those annoying "update available" notifications/reminders that keep popping up? I've gone into Settings, and in the Updates section firefox only let's me select auto updates or check for updates. I searched online but couldn't seem to find anything about how to disable the notifications all together with the newer version of FF. It's driving me crazy, thinking of switching browsers because of this. Thanks in advance!

Firefox 125.0.2 on Mac

When I press shift+cmd+D to bookmark all open tabs, instead of the links being saved to the designated folder, they are all saved to "Bookmarks Menu". The designated folder itself also appears with these links but it itself is empty.

I would expect shift+cmd+D to bookmark all links in the folder and the folder to appear in "Bookmarks Menu". This is what use to happen ages ago. I'm not sure what caused the change in behavior. Anyone have any ideas on fixing this?

Recently a popup notification came up when I opened firefox on my mac. Its been awhile since I opened it and without thinking I clicked : o ~ Now I worry if it'ss ledgit? Does Firefox give a popup box in top right corner when it needs an update? I wasn't on any strange website or anything but I'm always concerned and dont remember seeing that before.

My firefox now says its up to date after it restarted ~ it's running 125.0.3

Any advise is appreciated.

I just migrated to iMac 2019 27" with Venture OS from imac with Yosamanite. Firefox looked weird with TINY tabs and search window, Too much space. I've tried updating and restarting Mac but no change. Same with themes. You can see the screen with open Firefox.

Hey,

I use a personal firewall. Every unknown program that attempts to access the network triggers a popup message requesting permission.

Right after the installation, Firefox.exe initiated a message, stating the following path: "C:\Program Files\Mozilla Firefox\firefox.exe". I granted access.

However, weeks after the installation, the updater.exe asked for permission, stating a very unusual path of itself. The path is "\device\harddiskvolume3\Program Files (x86)\Mozilla Maintenance Service\update\updater.exe".

This seems unusual to me, since apps normally use 'C:\' to refer to harddiskdrive0. It is also suspect, since there are only two drives connected and the Disk Management tool (as an admin) indicates, that there are harddiskdrive0 and harddiskdrive1. There are no hard disk drives 2 or 3.

I also wondering about the fact, that the about firefox screen states, that firefox is up to date - even I did not granted access for the updater.exe in the past. There has never been a firwall rule to grant access for the updater.exe - how did it update in the past?

Does anybody have an idea what is happening?

Best regards, André

Using Linux Mint, Firefox 125.0.2

Why is Firefox autofilling the address bar with URLS I've never visited? There is a question on this from 5 years ago, with lots of suggestions. My problem is that Firefox is autofilling with sites that contain confidential login information.

In Firefox the date format is set at „month, day, year“, but I need „day, month, year“.

I tried all the solutions, I even installed Firefox - English (British) version, but nothing changes.

Can you also implement an alternative, to be able to choose between the 2 options?

Thank you very much.

Whenever I type in a website URL in the search-bar, first of all, the drop-down menu of related searches and websites does not show up. When I press enter to confirm that's where I want to go, nothing happens. The URL just kinda sits there, no loading circle or anything... Just a blank page. Only two of the icons on my toolbar works. The "Account" icon, which takes me to my Firefox settings. And my Extensions icon. Clicking the three little lines does nothing. The only websites i have been able to get to work at all are the settings page, and the Firefox troubleshooting page. I'm using Version 125.0.3, I tried using the browser both with and without hardware acceleration with results being unremarkably the same. I restarted Firefox and my computer multiple times to no avail, and the only thing I could find out of the ordinary was an error with Importing data from Microsoft Edge, which was not something I consciously wanted to do, but there was an error that popped up regarding that when i went to the settings page.

All that being said, I'm confused and at a loss for options, and could really use a Mozilla Staff member or someone who knows what they're doing to work me through this.

My primary/default browser is Firefox on Sonoma 14.4.1, and recently I'm unable to use the inputs of my audio interface for google hangouts. The relevant output is correct, and my system audio would be the same.

Dear All

We have recently found out that Firefox doesn't sync with Google My Business listings as when you search for “Saffery Geneva” on Firefox it brings up “Saffery Champness SA”, while on Google it correctly appears as Saffery (Suisse) SA as per attached print screen.

Any idea why Firefox is not syncing with Google with respect to this listing?

Many thanks.

On every new release of an update for Firefox, the update process deletes all of my saved cookies that I have established an exception for. I do this so that I don't have to continually enter my user name and password for sites that I visit regularly. The developers must change the updates so that the exceptions carryover to the new version of Firefox.
