Firefox supportforum

Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

Hi! On the latest version Mozilla Firefox 125.0.1 when i download .docx files i get the message 'File not downloaded: Potential security risk.' I select Allow download and the file downloaded can't be opened.

Thanks!

Hi, Before Firefox's Version 125.0.1 (64-bit) latest update I could download any file from my safe office environment, behind firewalls, VPN, ... Now despite of unchecking the "Block dangerous downloads" I'm still unable to download files. I have Windows 10 on my laptop.

Here are the steps: Click on a file, Save "File not downloaded. Potential security risk." Click on the message - Allow download The result is a file with content "HTTP Status 405 – Method Not Allowed".

Please help me to work the downloading again. I am aware of the safety but I want to switch off this feature.

Thanks in advance for help, Tibor

Every time I open a new tab, another extra tab opens automatically with the following address: https://0.0.0.1/

showing this message: An error occurred during a connection to 0.0.0.1.

I already re-installed Firefox but this bug keems popping up.

BTW: I did not do a d*** thing. It just started yesterday and is extremely annoying!

Hello,

James here. I CAN NOT find the Firefox application file location. There is no option to show file path upon right click of the desktop icon and I can not locate it in File Explorer. I have done an entire (C:) drive search and turned up nothing. C:\Users\(username)\AppData\Local\Mozilla Firefox does not exist in my file system. I am at a loss here and it's driving me bonkers!

Recently Firefox always has the error "failed to check for update". I have tried restarting my pc and running as admin. I am on windows 10.

I have been able to manually install the latest version by installing it over the top of my current install, how can I fix the error to be sure that my browser will auto update?

Thanks

In the recent update to Mozilla, all of my shortcuts disappeared. I had many, and can`t remember them all. Is there any way to restore my shortcuts from what they were a month ago? If not, I will switch to Edge.

I loaded the postcode lottery website but it's completely blurred. I last checked the same website last month, and it worked fine. I have cleared the cookies from Firefox, but the result is the same. It appears clear for a moment, then blurs. No pop-ups asking to accept cookies. It works fine using Chrome. Any idea why Firefox won't display it properly? It loads the National Lottery website, so it's not about gambling sites I guess.

I'm trying to configure my router and the instructions tell me to go to https://192.168.1.1. But the security settings will not allow me to get to that (local network) IP address, and ther.is no option to bypass the warning

I'm a game developer working on my first WebGL game from Unity. For the past day I've been banging my head around getting controllers to work, only to discover the issue is with Firefox - my build works fine in Edge and Chrome.

What's the situation with Firefox WebGL support? Is this likely to be fixed at any point or should I inform users Firefox doesn't work (and be pressured onto using Chrome or something else myself despite wanting to use Firefox?)

i had to rebuild my laptop computer and set up firefox on it, set up/turned on sync and the browser does NOT match the broswer srttings on the desktop where the sync comes from. bookmarked weblink icons only show up when a new tab is opened and vanish once a website is opened, icons for bookmarked weblinks on the bookmarks bar are generic wireframe globe-like-icons only, the custom firefox colour setup i struggled to create over the course of several weeks does not appear at all, nor does the dark theme. how then do i get this to -really- syc???

On FF 120.0.1 and Tab Reloader 0.6.1

I have FF set up with 7 tabs as home page, 6 of the tabs have tab reloader set to reload ever 1 hour. This has worked fine for years, the tab reload for the 6 tabs were saved after restarting FF. I didn't have to go back and tell tab reloader to reload after restarting FF. Maybe once and a while one tab didn't get the reload saved on a restart, usually always the same one.

Now when I restart FF none of the tabs have saved the setting to reload every 1 hour.

This has been going on for the last 2 releases of FF updates and there hasn't been any updates for tab reloader. Does anyone know why this is happening, I haven't changed anything in settings. I did uncheck hardware acceleration to see if that would fix another issue, but tabs weren't reloading after restart prior to that change on hardware accelation.
