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!

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

I am running the latest software, Sonoma 14.3.1 on my Mac Mini and the Firefox browser 123.0.1 With the last couple of versions of Firefox , after selecting About Firefox, I received the error message "Failed to check for updates" This happened a few times. I was able to manually update to the newer versions. How can I rectify the situation. My Firefox preferences under the General Heading has check for updates selected.

Help required please

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

So with Google becoming an increasingly terrible company over the years I once again decided to try to move away from chromium based browsers and over to Firefox, but I'm still having the same problem as I did when I first tried. I have since found the source of the problem, or rather a more exact explanation of what is going on, but I still can not find a solution. Basically when I compare the audio of the same YouTube video while logged into the same account with the same settings the audio quality on chromium browsers seems better. After some testing I figured out that it has to do with Logitech's G Hub surround sound option. Using Logitech's surround sound on headsets that support it, the Pro X2 in my case, will change the audio quality by quite a lot, in my opinion it sounds better. The problem is that this change doesn't seem to have an effect when using Firefox.

Is this a known issue and if yes, is there a solution?

I recently purchased a new Mac Book Pro. After migrating my data from my old one I noticed that when using Firefox my Facebook account was not working properly. I no longer could access my own page or the pages of friends. However, I could access some group accounts I'm associated with. On Safari, everything works fine. I suspect something must have been compromised during the data migration.

I deleted the Firefox app from my new computer and then reinstalled it but to no avail. When I'm in Facebook and try to access my page I get an error message. My OS system to up to date and apparently my Firefox is up to date as well. Any suggestions? Thanks!

Prior to update 125.0.1 corporate intranet users could download PDF files from our Line of Business applications / Webpages. Today after the latest update the PDF files download but are corrupted. The site was added to the trusted webpage without improvement.

Adobe Acrobat Reader could not open ********.pdf because it is either not a supported file or because the file has been damaged

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?)

Hi I am a longtime user of your browser. I have version 124.0.2(64 bit) installed on three devices. First thing I do on opening it is to click on "about", which normally updates the browser, before I do any browsing. In the last three weeks, however, it has not updated on any of the three devices, rather, it says "Failed to check for updates". I have tried the workarounds suggested at your Help center, and nothing has worked. What gives, may I ask? Thank you

I was on a teams meeting because I wanted to do a study session with someone on another country. As part of the homework I needed to do, I needed to listen to some audio. I changed my windows audio devices to output through the Communications device for the headset. Then I played the audio on a tab. The audio played for a few seconds before stopping again.

I understand that this is behaviour intended to let you take a call or meeting without having to manually pause any open tabs you might not have at hand, but I would like Firefox to understand I really want that audio to play without thinking it knows better. Is there any way to disable this behavior?

The full website link has /users/login, but when I checked the saved passwords, the link stops before the first /, its just websitename.com, instead of wesbsitename.com/users/login, and I suspect the full link not being save is whats causing it not to show up. Is there any way to brute force it to show up?

In order to view a PDF, I cannot just open it, I must download it. I tried the solution offered by Jefferson Scher and it didn't work. I'm using the latest version 119 of Mozilla which I downloaded today. 10/26/23

I am having a significant issue with firefox draining my battery. I used chrome up until the new year and then switched over to firefox from chrome. Overall I love firefox so much more. The format is way more pleasing. I love how it easily signs me back into everything, BUT IT DRAINS MY COMPUTER SO MUCH. Like i used to have an 8hour + battery span my laptop neverrr died. Now I get through MAX 2 hours of full use before needing to charge, and maybe 4 hours just having it at school but not using it.

I thought my dell suddenly started crashing, ran all these tests, and then I realized the only change was that I had started using Firefox... So sad I think I am going to have to leave it.

I read a lot of articles and did everything suggested. my graphics is webreader , i turned on all the suggested features, i have 2 extensions , the only thing I could maybe think of was that I use an animated theme so maybe that was killing the battery, but like if I can't use my theme than whats the point.

I'm having really odd behavior using Firefox (linux) with Microsoft 365 web apps (outlook, word, excel, etc). Its happening various distros too. Is there a known issue at this time with FF and 365 web apps?

   Excel - cell content deletion on moving through cells.
   Word - line content deletion on hitting carriage return.
   Mail/Cal - Webapp not displaying content on double clicking emails or calendar events.

Found a few sporadic similar reports from users on various forums, but no official note that it was a known bug. Assuming it isn't widespread - anyone here have any anecdotal reports of similar issues. Seems to only affect the linux distro versions of FF.

This renders the web app sites unusable with Firefox so I have had to use another browser for these apps. As these apps are ubiquitous with work and productivity, it's rendering Firefox as a second-choice browser unfortunately. No one really enjoys having to "pick the right browser" for work or play.

Is there any way to resolve these issues? Hoping someone has some insight.

i’m trying to open blackboard.com but it keeps telling me ( Did not Connect: Potential Security Issue ) some youtube guides say that you can modify the enterprise security roots from *false* to *true* and it will work, but is it safe to do that? and is there any solution the problem?.
