I can't install Mozilla VPN on MacOS 10.15.8. The installation programm tell me to ask for help to the editor of the VPN... I'm afraid that it's possible there is NO version available for my old machine... Am- I right ?

I have just purchased the latest version of Mozilla for OS. My computer is older and the operating system is Monterey 12.7.6 I am assuming that my computer's operating system is too old and the new mozilla will not support my Monterey system, correct? Is there another Mozilla version I can download?

Using last Windows 10 install, and 153 esr.

Manually entering an address in the address bar sends it to search.

The advice from 2020 found with a search online, and in Mozilla Firefox support, does not solve the problem.

Not only is it a time-wasting obstruction for a new page to open and put the address at the top, it is a problem that the address bar can not be used as intended for manually entered addresses.

I'm guessing the problem is also responsible for the problem of clicking on a link in a program not opening it in firefox in Firefox. I have two programs setup, correctly, to open Firefox or go to the open browser when I click a link. I get a return in both cases that the browser may not be installed correctly.

I installed the browser as usual. Currently: 153.2.0esr I had 153.1 installed, however there was an unrelated (presumably) Microsoft problem and I had to restore. 153.1.0esr disappeared from my computer and online. So I downloaded 153.2.0est. However, both of these problems have manifested since updating to 153:

• Address bar does not function properly when adding a manual address.
• Clicking on a link in a program no longer opens the link in Firefox

I downloaded the full install program, as usual, and installed on top of the current install so my established profile is used. There are no major changes - except when features have become dysfunctional.

Searches online and at Mozilla support make clear these are current Mozilla Firefox issues. I can find no mention of either problem in Mozilla support.

Is there a solution to either or both of these problems in 2026?

p.s. I have no intention of upgrading to Windows 11. I also have updates disabled, however that did not stop microsoft from surreptitiously installing Snapshots and a personal A.I. app (evidence of which is in the registry which I deleted). The computer was lagging and glitching and running the disc almost constantly. So I went looking for what Microsoft had done - again - without my knowledge or opportunity to consent (or not) and found the culprits. I also found entries in Explorer directory for both features and deleted them.

Dear Sirs! I've been trying to install FF in several ways. Using installer.exe and setup150.exe. I started these files from same disk as the system (C), Temp folder empty and unlocked for read\write, located where it should be C-user-appdata-local-temp. I started files as administrator. Each time the setup fails with system notice like on the picture attached. It says "can not find specified file"

My notebook is very old, but it runs Win 10 OK, Chrome is OK also

Intel(R) Core(TM)2 Duo CPU P8400 @ 2.26GHz 2.27 GHz 4,00 Gb SSD 224 GB SSD P4-240 Mobile Intel(R) 4 Series Express Chipset Family (Microsoft Corporation - WDDM 1.1) (64 MB) x64 system

Please help!

As my title says i cant move Firefox from desktop because it is *the* browser file not a shortcut, and every time i try to move it to any different folder it just creates a shortcut in said folder. I asked Copilot how to reinstall it, set it in actual search mode so i could have 100% reliable steps, nothing worked! >:ε

so im asking yall if there is a way to fix it, thanks in advance

I deleted the Google search app, and attempted to acquire Firefox, but I get a message that something happened and the download was incomplete. I have tried reloading the app and keep getting the same message.

Es que use un cable USB para poner el Firefox por qué el explorer ya no está actualizado y puse el Firefox que descargue en la computadora y me dijo ue no se puede

Resolved Update: apparently cat cannot write to /etc. Resolved by using:

sudo tee /etc/apt/sources.list.d/mozilla.sources <<eof types: deb uris: https: packages.mozilla.org apt suites: mozilla components: main signed-by: etc keyrings packages.mozilla.org.asc eof < p></eof>

The instructions need updating!

_________________original problem (in case some one else needs the information)

I am following the instructions in section "Install Firefox from Mozilla Repository (Recommended)" at https://support.mozilla.org/en-US/kb/run-firefox-chromeos At step 4 I am receiving a permission denied error: "-bash: /etc/apt/sources.list.d/mozilla.sources: Permission denied" I am not sure how to resolve or continue.

Last command and output:

username@penguin:~ cat <<EOF > /etc/apt/sources.list.d/mozilla.sources Types: deb URIs: https://packages.mozilla.org/apt Suites: mozilla Components: main Signed-By: /etc/apt/keyrings/packages.mozilla.org.asc EOF -bash: /etc/apt/sources.list.d/mozilla.sources: Permission denied

The latest version of Firefox (installed today) just crashes when trying to open any tab and will not reload anything. How can I reload the last working version? Kind regards Stephen.

I don't think the install finished correctly I am sending this from Chrome.

Kind regards

Stephen
