It is really sad that there is no way to contact mozilla directly The update installed on my Windows 7 64 bit is now storing cookies for Proton Mail and that makes the storage amt increase from 29Kb to 78Kb and I am not happy that I can not find a way to remove or revert the update so detail steps to complete that process would be nice. As for my future use of Firefox and involvement with Mozilla I am very seriously considering NO further use of both and your claims are starting to become lies you are permitting tracking in my view of this behavior Community Members should not be dealing with these concerns GET OFF your lazy back side Mozilla

After an update Firefox won´t let me add extensions.

Hi! I´m using Jdownloader2. After an update of Firefox the captcha-extension of JDownloader didn´t work anymore. I reinstalled Firefox, but adding the extension is still prevented. Following quote appears: "Firefox hat die Website daran gehindert, Sie zu fragen, ob Software installiert werden soll" It should be in yellow (but it isn´t), like following site describes: https://support.mozilla.org/de/kb/Add-ons-koennen-nicht-installiert-werden#w_firefox-hat-die-website-daran-gehindert-sie-zu-fragen-ob-software-installiert-werden-soll Furthermore there should be a button to authorize the installation. Instead there is only the button "OK". I followed the help-site mentioned above to the letter, to no avail. By the way, I´m using Nightly now, but JDownloader2 automatically wants access to Firefox. Would you please tell me, how to add the mentioned extension. Without it I couldn´t download most files! Please answer to following email: [redacted email from community support forum]

My C hard drive is almost full. How can I get Firefox to run from the D drive? I tried copying the files there but it would not run. Do I need to edit something in the Registry? I'm using (for as long as I can) Win 10 on a Dell desktop. Latest version of Firefox is installed.

Thanks for any assistance.

If I have to restart my computers when I am in the middle of working because Firefox won't work unless I do, I will find another browser. And yes, I have it set to only update when the computer is not being used, but obviously that does work. Maybe give me the option to set a time to restart?! Like the middle of the night as opposed to the middle of a working day!!!!!!!!!!!!!!!!! Really???????????

Almost everything in software disappeared on update

Firefox auto updated when I opened it today. Then when it opened, all that was on the screen was the menu (file edit view history bookmarks tools help), the "search or enter address" box, and in the upper right hand corner the words "private browsing" with the purple circle and eye eyeglasses icon. That's all. I have tried looking at my profile. It seems to still be there. This seems to be a problem with the Firefox software itself. I have re-downloaded the software three times, the last time I uninstalled Firefox from my laptop and totally reinstalled. Every time I get the same results. This almost blank screen. Let me be clear. There is no purple background, there is no Firefox icon, there are no tabs, there is no customized menu bar, there is no search box in the middle of the screen. I'm working on a Windows 10 laptop 64 bit. Please don't tell me to upgrade the Windows 11, the laptop won't take Windows 11. I get the same window whether I open the regular fire fox or the private browsing Firefox.

I wish to export, and not copy, a digital certificate so that I can import it to Keychain on my Mac. The only option in Firefox Browser on Mac is to copy, which means it only opens as a TextEdit and cannot be imported.

Any recommendations?
