Firefox Community Forum

On the latest update to firefox, the browser now has a vetical tab in addition to the horizontal ones. I want to remove the vertical tabs, and ideally for it to never come back. I've searched the settings as well as the support features and can't find a way to turn it off. I am legitimately not going to use firefox at all until this issue is resolved.

Thanks

I know that typically mozilla does not put a low bound on advisories, and https://www.mozilla.org/en-US/security/advisories/mfsa2024-40/ is the advisory for vulnerabilities fixed in ESR 128.2. CVE-2024-8387 is listed here. yet the advisory for 115, https://www.mozilla.org/en-US/security/advisories/mfsa2024-41/ does not list this vulnerability. Was this something that was only impacting 128 (for the ESR builds) or is there a mistake that either 115.15 did patch it but it wasn't documented, or the patch has been missed and ESR 115 is still vulnerable?

Hello,

I've tried running "firefox -P". I've also tried deleting ~/.mozilla. No matter what I do, I still keep getting this message.

OS: Linux 6.10.13-3-MANJARO Firefox versions: firefox 131.0.3-1 installed from the Arch repo via pacman; also firefox-132.0.2 installed from tarball downloaded from firefox.com and unpacked as /opt/firefox.

With firefox 131.0.3-1, I get the following error message:

[Parent 33389, IPC I/O Parent] WARNING: process 33445 exited on signal 9: file /usr/src/debug/firefox/firefox-131.0.3/ipc/chromium/src/base/process_util_posix.cc:335

With firefox-132.0.2, no messages are printed.

What is even more confounding: I have 2 user accounts on this computer. When I login as myself, I get this popup. When I login as the other user, firefox opens up fine.

I've already looked at the following, but that has not helped. https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles https://support.mozilla.org/en-US/kb/how-run-firefox-when-profile-missing-inaccessible https://support.mozilla.org/en-US/questions/1327628 https://support.mozilla.org/en-US/questions/1396772 https://support.mozilla.org/en-US/questions/1454745

I'd be most grateful if someone could please suggest any other alternatives to try. Thanks!

After updating Mozilla Firefox to the latest version, it changed the default language from English (US) to German (DE) although English (US) is currently selected as the default language. It will not change back to English (US)

Good morning,

When I attempt to download the Firefox 115.16.0esr 32 bit download from the site it will only supply me with the Firefox Setup 128.3.0esr. I have tried several times with the same result. Given my PC is far from thr newest (funding prevents large outlays) I must continue with my older 32bit system but try to keep as current as possible with updates.

Please can you advise as to what is going wrong or where I can download the update I need?

Many thanks in anticipation,

John Andrews

I have used Firefox for longer than I care to remember and have never had any problem with it but this morning I switched on my PC and a new AI side bar has appeard on the left and I don't want it. Can you please make it so we can remove it and looking around the internet, I know I'm not the only one with this opinion.

I have loved FF desktop browser since I started using it per my boss in 2003. But I am so tired of the fact that EVERY SINGLE TIME you put out an update it breaks my access to the bank. EVERY SINGLE TIME. I waste HOURS reading articles, calling the bank IT dept, chatting with people who are on 3 calls at once, only to hear them tell me to "just use chrome." I clear the cookies, clear the cache, reboot, follow all the prompts in the settings and THEN the damned bank server doesn't recognize the device so it forces yet ANOTHER password change. It happened again TODAY and it makes me so sad but I cannot do it anymore. I am STILL now (going on 4 hours) trying to access the billpay page @ Xantanderbank. (ahem, secure codename) I am forced now, by this craziness, to use the imbecilic duckduckgo which is A) and offensive name and b) you KNOW it nowhere near the product you have built but I CANNOT DO THIS ANYMORE. Thank you for the time it takes to read this diatribe. I appreciate it.

Dear friends, I recently realized that Mozilla Firefox does not support Windows 7. At the same time you want people to prefer your browser. Why did you stop supporting Windows 7. I think that window 7 is an OS used from thousands of users. I prefer to use this OS and Linux Mint. So, I do not understand your policy not to support this OS. Thank you in advance for your answer!

Latest update, 4. oct. Using Firefox Developer Edition. Closed the browser window for the day, and then on opening again it had updated, my entire toolbar, and also icons where the tabs are, are just gone - including the "+" icon for creating a new tab, along with the bookmarks bar having vanished. Picture added below.

It seems like the bookmarks bar is still there, you just can visibly see any bookmarks. Tried adding a new bookmark, but nothing appeared.

How can I fix this?

I'm an IT support professional and in our environment we are still running few servers (for multiple reasons) with OS version Microsoft Windows Server 2012 R2 Standard and Microsoft Windows Server 2012 R2 Datacenter and they have currently Mozilla Firefox ESR (x64 en-US) 115.15.0 installed. I couldn't find any clear answer, hence I've created this ticket - is Mozilla Firefox ESR 115.16.0 supported on this OS ? - usually you are not referring to Microsoft Windows Server in you release notes info - f.ex. https://www.mozilla.org/en-US/firefox/115.16.1/system-requirements/ so I need clear answer. Also I cannot download Mozilla Firefox 115.16.1 from https://www.mozilla.org/en-US/firefox/115.16.1/releasenotes/ - if I click download it always downloads Mozilla Firefox 128 instead. So please let me know if there is any Mozilla supported version for Microsoft Windows Server 2012. Best Regards, Milosz Wrzalek

I have a user at my job that installed the latest Firefox update (13324.11.21) through our MDM. After installing this update she cannot launch Firefox. When attempting to launch she receives a request for a username and password to install a Helper Tool. She is an admin on her machine and enters her credentials. The message closes and nothing happens. When attempting to launch again the same thing happens. This is not happening with our other 100 Macs who have the same Firefox version and others who have the same OS.

Is anyone able to tell me why this is happening or how to fix? Any assistance is very much appreciated.

The below troubleshooting steps have been done:

Uninstalled and reinstalled Firefox

Updated the OS to 15.0.1

Disabled the Master Password on Firefox through a Mac Profile

Checked if there was a Firefox file under /Library/PrivlegedHelperTools

Granted Full Disk Access to Firefox under System Settings

So, I don't have an issue, I just want to scream because my firefox crashed and when I started it back up it asked me about booting it in safe mode or something, but I didn't want that and the other option was 'refresh firefox'

Nowhere AT ALL does it warn you that it will WIPE your current installation and RESET everything. I had no ideas and had not saved up the content of my OneTab extension in a while, FUCKING THANK YOU FOR THAT.

That's it. Fuck you.

Currently on 131.0.3. Started having this issue around the time 131 dropped.

I press Ctrl-shift-O and bookmarks manager won't open. Bookmarks manager opens normally if I use the menu to open it. Keybind won't work in troubleshooting mode so I know it's not an addon, and the hotkey works fine on other computers with Sync enabled so I know it doesn't have to do with my synchronized settings. Also won't open with a fresh profile so I am very hesitant to reset all my settings.

I use this keybind multiple times per browsing session so it has had a major impact on my usage. Not sure what to do. Please help!

I'm going to try a graphics driver update in the hope that helps. This is on Windows btw.

Since Mozilla Firefox web browser v127.0 (released June 11 2024) the manual installation of the Adobe Acrobat Pro extension (the adobe_acrobat-1.0-windows.xpi file) do not work anymore!  :disappointed_face:

So, when you go in any higher version of Mozilla Firefox web browser then v126.0.1 (released May 28, 2024) to this web browser Menu Bar -> Tools -> Add-ons and Themes -> Extensions -> Install Add-on From File..., and then try to manually import-install the Adobe Acrobat Pro extension (the adobe_acrobat-1.0-windows.xpi file) into the Mozilla Firefox web browser, and from this HDD location:

C:\Program Files (x86)\Adobe\Acrobat DC\Acrobat\Browser\WCFirefoxExtn\WebExtn\signed_extn\adobe_acrobat-1.0-windows.xpi

The Mozilla Firefox web browser will say during this .xpi file installation: "This add on could not be installed because it appears to be corrupt"!  :disappointed_face:

However, in any Mozilla Firefox web browser version prior v127.0 (released June 11 2024), this manual import-installation of the adobe_acrobat-1.0-windows.xpi file will be most successfully installed in a Mozilla Firefox web browser without any problem!

I also create the most detailed and step-by-step post on the Mozillazine.org Forum and the Adobe Forum about all of this problem:

So, please help and advice further. Thank you in advance and best regards!

I have updated Firefox from 115.16.1 to Firefox ESR because I use a Mac running OS 10.13.6. Is there a way, hopefully an easy way, to import all of the bookmarks and extensions I was previously using in 115.16.1 to ESR. Hope so. Thanks!
