Firefox Support Forum

Since downloading the latest version, the browser stops functioning after the first site. It won't even allow me to quit, without the 'force quit'. Plus, while in the first site (my local newspaper) it stops recognising key strokes and mouse clicks. In fact, everything stops working.

I'm sending this through Chrome.

Any fixes?

Thanks, Stan Nikolic

Firefox stopped working on MacBook pro running OS 10.13.6. I deleted the app and tried to download a new one, the icon is crossed out and a prompt saying the app may be damaged or incomplete. Nothing had been changed on my system when this happened.

I try to install add-on for Firefox through Windows Registry entry. In this article: "https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Distribution_options/Add-ons_in_the_enterprise" - described that I should specify the location of the xpi-file. For exemple, instal "uBlock Origin" by CMD script:

reg add HKLM\SOFTWARE\Mozilla\Firefox\Extensions /v uBlock0@raymondhill.net /d D:\Download\ublock_origin-1.18.6-an+fx.xpi

If I want instal add-on from URL? I try do this by CMD script:

reg add HKLM\SOFTWARE\Mozilla\Firefox\Extensions /v uBlock0@raymondhill.net /d https://addons.mozilla.org/firefox/downloads/file/1709472/ublock_origin-1.18.6-an+fx.xpi

But, nothing work! Is it possible to install add-on by downloading xpi-file from URL (AMO domain)?

Search for the addon on mozilla addons.

Locate UBlock Origin and click install. The popup is displayed to 'accept' permissions. Click accept and nothing happens. In the addons 'extensions' tab, the ublock entry row shows, but it never starts to download (and therefore never installs).

Tried to do it by saving the xpi to local and installing from there, but exactly same thing occurs.

Firefox 60.x ESR on Linux (slackware).

Is there anything else I might try please ?

Kan Firfox niet meer installeren (en weer verwijderd)en krijg voortdurend de melding dat mijn profiel oid niet te vinden is. De technische tips snap ik niet. Een vierkantje op een toets met de r indrukken? Welk vierkantje?

Wie of wie kan mij op weg helpen? En graag in het Nederlands, als het kan.

When I try to install an addon, A popup window appears asking for permission to access to some things on my computer. I cannot click the either the cancel or the allow buttons on the popup window. That tab hangs up until I click on another tab.

First of all, I am not qualified to use Linux, although I have been running it for several years with mixed success. I recently installed Firefox version 62.0, which is not great, although it is much better than Debian's Firefox ESR.

I used some special method which turned up on a DuckDuckGo search. As a preliminary step, it had me install something called Snap. The whole installation process was simple, virtually automatic. However, since Sept 21, I have been receiving notices that Firefox is unable to download version 62.0.2. I have also been unable to download v. 62.0.2 manually.

I used the "locate" command which indicates that several Firefox files are in directories such as "/var/lib/snapd/desktop/applications/firefox_firefox.desktop," among others. I suppose that Firefox is looking for a certain file in a directory, which is in one of these snap or snapd directories.

I am reluctant to attempt to uninstall ver.62.0, and then attempt to install ver.62.0.2. I believe I could download and install the ver.62.0.2 tarball, if I knew what directory to download it to. Can you tell me what the name of that directory? If so, I might be able to find that directory in the snap or snapd directories that I have.

Thank you for your courtesy and patience in assisting with this matter.

Drive C: is tight for space. When I install the developer edition I get no opportunity to customize my installation options and the program installer installs to c:.

How to direct the installer to install to D: instead?

I had firefox before but I encountered issues updating so I decided to uninstall it and do a fresh install and that is where I have been having issues with. I have been unable to reinstall firefox on my system. The only time it went through, it gave me an error message "couldn't load xcom" so after researching on how to solve that I uninstalled again and tried a fresh install but after that the error message I keep getting is not enough space on disk and later "for some reason firefox could not download" Please I need help. Thank you.

Pop up window continually appears telling me that the Firefox browsing protection is not installed. When I try the install now I am told that Firefox needs to restart to complete the installation. When FFox restarts the same warning reappears and this always happens. I am using TalkTalk as my providor and when I check the browsing protection here it warns me that the Firefox is not installed but when I now try to install it the same routine occurs about restarting FFox and it does not install. Can I install it or if not prevent this stupid warning appearing all of the time?

Hello,

We have a browser extension for FF that is called "Email Signature Rescue". When I`m trying to download it off this link, it is successfully downloaded and I can add it to FF. I`m located in Ukraine now. But when my colleagues in Australia try to download the extension and install it, they get a message that add-on is corrupt or some can`t even download it and get a message about the connection failure. Here are examples: https://s3.amazonaws.com/uploads.hipchat.com/136989/993119/FsYm1tsNx5rkWog/upload.png https://dl.dropboxusercontent.com/s/tgd7aotis6qg40e/Screenshot%202018-05-03%2021.53.54.png Do you have any thoughts on why some users can successfully download and install the extension and some get an error?

The link to the extension is placed on our website here https://emailsignaturerescue.com/email-signature-rescue-software/browser-extension I attached screenshot on where exactly you can download it from.

Thank you for your help in advance!

Hello I recently downloaded the latest version of Firefox 54 for Linux. Everything worked great however even after making it the default browser links from external programs such as Pidgin won't open in a new tab in firefox. Instead a new window will pop-up with my home page. I've tried solving it by uninstalling the other version of firefox I downloaded from the repository (Firefox 45)

I fear it might be because I didn't really install it, instead I just ran the file directly form the download labed just firefox. It seems to be working fine and there was no README file so I assumed that was the way it should've been done.

When I'm working or watching videos on YouTube, for example, I keep getting this damn popup. "A recommended security and stability update is available, but you do not have the system permissions required to install it. Please contact your system administrator, or try again from an account that has permission to install software on this computer. You can always get the latest version at; https://www.mozilla.org/firefox/". I'm using a user account, not the Administrator account. I'm fed up with these popups appearing in the middle of my screen when in the middle of work or trying to relax when I'm watching a video. Such popups are supposed to go to desktop not in my face when I'm in the middle of something. How do I stop it?

I had Firefox and Thunderbird installed the D drive. The D drive died. I try to reinstall on the C drive and it installs but when run says that the profile is not available (same for both programs). I have deleted all reference to mozilla in user>appdata and the same happens. Tried running "firefox -p", with the same resulting message. Back to Opera?

The "OpenH264 video codec" provided by Cisco is not being installed on any of the PCs in our company. And we need to have them installed... I've tried to install manually without any sucess and also tried the other solution I saw online. None of them worked for me. How could I fix this issue?

I have tried restarting my device. The first timeni tried downloading it and playing the game it worked but then 2 days later it said that i have to download. i hope you can help. thanks

I am unable to install the yahoo toolbar and roboform. I used to have those before no problem. I have since got a message telling me that they are not supported on Firefox. I tried to uninstall and reinstall firefox but when I try to install either roboform or the Yahoo toolbar I get a message telling me that the software is corrupt and will not install.
