Firefox Community Forum

I tried to open Firefox and a message appeared: "Couldn't load XPCOM". I uninstalled the program with Revo Uninstaller Pro and downloaded the latest version. I selected Run as Administrator but there is a message that says "Windows cannot have access to the selected device, path or file. Maybe you don't have access rights". However, I do have access rights. I have checked it multiple times. How can I install Firefox and see it work properly? Thanks

Some of the firefox built-in search engines have several comma-separated associated shortcut keywords in Settings/Search/Search shortcuts, e. g.

• @duckduckgo, @ddg for DuckDuckGo

But if I type in several comma-separated shortcuts for any other search engine, none of them will work as expected in the address line. What is the correct way to assign several keywords for the same search engine, like it is already assigned for some default engines?

Dear folks , Every time I click on Firefox for web search , Fragilepottery.com comes up , I simply cannot find a way to delete Fragilepottery , should I uninstall Firefox and install Firefox again ?

I have ugpraded to a new macbook (from an intel macbook, this is my first apple silicon macbook - M4 Max). I am having trouble logging in to many of my accounts only when using firefox on my new macbook - eg. soundtoys, spotify - the only way I can get the logins to work is if I run an incognito window to log in. Is there a fix for this? Best, Joe

After yesterday's update, I'm not able to access files in Google Drive using Firefox on Windows. They're greyed out, and when I try to open one, a pop up informs me "This file can't be opened because you're offline." I'm certainly online, and it works on Chrome (ugh). Anyone else experiencing this?

Dear Mozilla Support Team,

I am working on configuring Microsoft Intune for organization and need to manage specific settings for Firefox via Custom CSP policies. However, I could not locate the necessary OMA-URI details for the following Firefox settings:

Advanced Options: Check my spelling as I type Advanced Options: Preference State Advanced Options: Use AutoScroll Advanced Options: Use Smooth Scrolling Disable XPI Installs These settings are crucial for maintaining compliance and ensuring a smooth user experience within our managed environments. Could you please provide:

1. The exact OMA-URI paths or equivalent policies for these settings? 2. Additional documentation or resources related to Firefox Enterprise policies for Intune?

I have created a new Firefox profile. Now I want to copy my settings of the Developer Tools to this new profile. This should also include the custom device settings for the Responsive Design Mode. Is there a file (or files) in the profile-folder that contains these settings, and can I copy this file (or files) to the new profile? I found this link about copying profile files, but it doesn't mention devtools settings.

to get access to my bank account via Firefox the bank should send me an access code on my mobile. The page pops up on Firefox, I wait for the code but there is nothing coming onto my phone? I can access my bank via a different website so am wondering if there is a problem with Firefox. By the way, my mobile functions correctly and I receive calls.

Twice now in the past couple of months this has happened to me:

Restart to Keep Using Firefox

An update to Firefox started in the background. You’ll need to restart to finish the update.

Your windows and tabs will be quickly restored, but private ones will not.

EVEN THOUGH in my Firefox settings this is set to no automatic updates.

What is happening?? How do I turn this off! This seems like a virus? Please advise.

the following files couldn be attached outlook web Microsoft Outlook in firefox. Its files more 1 MByte. clearing the cache did not solve the problem. Outlook web in Microsoft Edge no problem with attach files Firefox version 133.0 (64-біт)

I prefer the tabs be below the bookmark bar, and successfully modified the CSS file to do this some time back. Now update 133 has once again pushed them up below the menu bar. What do I have to do to get them back where I want them this time? And why can't you just leave the tab location preference alone when doing updates?

I had my application running on the Firefox earlier version where the an insecure content loaded over http from my server was being displayed on my webpage which is on https.

But with the latest versions of firefox this solution is no more working. For example the below i have a pic loaded from my server path say http://10.16.15.2:9181/pic/Pic?id=41234 .Now i need this to be displayed on my secure web page application, but the firefox browser is automatically converting to a https path. See the output from the debugger console

" Mixed Content: Upgrading insecure display request ‘http://10.16.15.2:9181/pic/Pic?id=41234’ to use ‘https’ "

Kindly suggest a way to disable this auto conversion in the latest versions of firefox, as i have no option to update the front-end or back-end of my application.

Thanks for your help in advance

I have a 1848ETC-HST data logger from Real Time Automation on an isolated network that does not support HTTPS but Firefox keeps changing it to HTTPS. I tried a private window with the same results. HTTPS-Only Mode is disabled. I entered an exception even though it should not need it. It was working in Firefox at one time and it still works with safari and chrome.

Google Drive says i am offline when i am not. Can move around the site, and it works fine on chrome, but not on firefox. Can also acces sheets just fine, and acces some files through there

tried contacting google, but since it was a firefox specific problem they could not help
