Firefox supportforum

There's not really much skirting around it. Yesterday, I came across this sudden error with my Firefox browser on PC (see annexed image), which basically rendered me unable to open it for some reason. It did get fixed that same day somehow, though for a short while, as I was faced with the same error message again today and once again haven't been able to open my browser, much to my frustration.

I tried searching about it on the internet, but didn't find anything of help – most videos about it refer to a mistake on the Windows OS with the same code (0xc000185); asking around to people I knew didn't do much, either.

Today I tried a bunch of stuff to see if it resolved my problem in any way, such as: 1. Restarting my laptop (didn't work); 2. Installing both suggested and optional updates available to my Windows version (put me at ease a little, but still didn't work); 3. Searching for malware (antivirus didn't find anything, so I'm thankful this one didn't work); 4. Verifying system files with 'sfc /scannow' (all was good, so it didn't work);

I was also going to try doing a 'chkdsk /f /r', but I didn't have time to, as I had to leave for something. There are also other things such as creating another profile, which I'm considering; updating Firefox, which I can't do because I can't open the browser to check if there are any updates; and reinstalling Firefox, which I'm slightly afraid to do and will leave as a last resort because I don't want to risk accidentally doing it wrong and losing all my history, bookmarks, etc.

Any help would be incredibly welcomed. Thanks in advance.

P.S.: The text on the error message reads (translated from PT-BR): "The app couldn't be started correctly (0xc0000185). Press OK to close the app." Sorry if the photo isn't very good.

Looking for a fix on a right-click issue that I keep having...

When using Linux Mint (Cinnamon), the right-click context menu occasionally becomes misaligned with the cursor position. Attached image shows a right click on the text box in the right browser window triggering a popup in the left browser window.

This most frequently happens when:

• Multiple windows are open AND
• The window being right-clicked on is "snapped" into place (by dragging to the side of the screen)

Error seems to occur most frequently on windows snapped to the right-hand-side of the screen.

Context menu placement is offset by an arbitrary amount determined at time of window-snapping. E.g., moving the cursor down 1 inch in the example image below will move the menu down 1 inch as well. Un-snapping the window, and re-snapping can adjust menu-cursor-offset distance.

When logging into a Wordpress site on Firefox, hovering over Username displays a gear (see first screenshot) which when clicked on exposes passwords and allows them to be edited (see second screenshot). This does not happen on other browsers. I'm on Firefox 126.0, MacOS Big Sur 11.7.10

Hi guys.

Need some help. I can't download any files using Firefox. It always says, "Failed".

I tried other browsers, and I'm able to download just fine.

I already tried this guide, https://support.mozilla.org/en-US/kb/cant-download-or-save-files, but still same.

I haven't tried to re-install Firefox because I have a bunch of workbook marks that might get lost. So, I want the re-install option as a last resort.

Thanks~

Firefox is synced on all my computers. Same version. Same extensions. I can't login on my primary desktop as of last night 5/23/24. I can login/watch Prime on my laptop. My desktop gives me the attached error.

Shoot!! I just filled this out, and somehow, it reverted me back to This screen again!! I am not a programmer or IT Guy. What I am is a person that is Very alert to sudden changes in my experiences. I retired 14 years ago, as a Manager in a Manufacturing industry. Very familiar using desktop. For some reason, about a couple weeks ago, some of my sites have begun using google adds, over and over. When I click on the "X", wants to know why, etc. I use Malware Bytes, scans every day. Does NOT discover any malware, but I KNOW something has changed to allow the bombardment! Is it possible it's just a single site that I had to change and log in to? Even if so, WHY doesn't Malware stop them? Should I try a system restore to weeks ago? I am on here Every day.so I'm pretty cognizant of changes! ADVICE PLEASE!! Bruce Pierce

Thanks in advance for any insight or suggestions. My preferred browser is Firefox. In Chrome, I can easily use a voice search from www.google.com. In Firefox, the permissions show my preferred mic as enabled and selected for that webpage -- but no sound is detected. (Using Firefox. mic works fine at https://www.onlinemictest.com.)

(BTW, speaker output is Realtek motherboard audio and mic input is a Shure X2U USB interface. This mic works just fine in zoom, whereby, audition, etc. as well as working google.com using chrome)

Have worked through various settings in the SOUND panel and SITE PERMISSIONS with no luck.

Any ideas about this problem -- or what other settings to trouble shoot?

Thanks!

Hi there,

On the 23. of Mai I first noticed that I am unable to download any files whatsoever. I tried downloading .exe files and also a .csv file. When I try to download one of these files it appears in the downloads window but immediately goes to the status "Failed". Any retry fails as well.

The same thing goes for extensions. I cannot download any extensions or plugins using my Firefox browser. Since I reinstalled Firefox I can now also not use Plex because Firefox can't install the required plugins.

I will attach screenshots of all the errors I get.

All of the above worked when I tried it on the Edge browser.

Firefox version: 126.0 Windows 11

Things I have tried to fix the issue:

• Use the network connection from my phone instead of my home network
• Disable firewall and windows defender
• Reinstall Firefox
• Refresh Firefox
• Downgrade to version 125.0.1 and 122.0
• Reset router to factory settings
• Flush dns
• Restart PC
• Manually delete profile folder
• Delete temp files
• Change download destination
• Disable "Block dangerous and deceptive content"
• Troubleshoot Mode

Is Firefox using some other temporary folder for downloads?

Any ideas on how to fix this issue would be appreciated.

Thank you.

Please approve the update to Twitter X Ad Blocker. I've chatted with AldAstra Labs the creator and they have an update but are waiting on Firefox to approve it.

Thanks, Tracy

If you experience horizontal lines appearing when scrolling after installing firefox possible fix is finding layers.acceleration.force-enabled and set to true after going to about:config in your address bar search for this and set it to true. My real question I ask myself is, why isn't this enabled by default when installing firefox? I swear I remember doing this last Win 11 install as well. My third time installing windows unfortunately, just had a nvme ssd drive fail on me. 😭😢 Ofc, it had to be my Gen 4, C: drive with my old User account on there as well. :// Lesson learned, always backup important data frequently as desired. :( Oh well, just lost all my saved games and few songs, no big deal I guess.

No idea what the cause is but I cannot download ANYTHING on my browser for some reason. Pictures, documents, executables, browser extensions. Tried downloading documents from email attachment.. fail Tried downloading VLC... fail Tried every default recommended solution, clean install, you name it. Mind you all of these files downloaded just fine perfectly via Microsoft Edge.

Noticed another abnormality. Changed the download folder to a custom one. Download failed and DELETED the folder for some reason.

Everytime I open Firefox a new window opens suggesting I add the AVG extention, when I do I get a notification that AVG does not support that extention for Firefox. Why is the nonsupported extention being recomened

I had implement service worker for install resources and activate service worker and fetch the resources at offline.

When online service worker worked and once serve the resources to the cache then it will be stooped automatically

but when offline service worker block the local host and can not cache resource from cache. I am using firefox

126 version on window 11 system

Any settings are required or help me what will do for offline working in firefox using service worker

Firefox uses about half a gig on my disk, that's: '~/.mozilla' and '~/.cache/mozilla' can that be reduced? Either some setting that limits disk use or even a manual deletion of ancient stuff?

Hello.

Hey, I have been trying to figure out native Firefox solution for deleting firefox history after it's set number of days old. I did found solutions for older verions of firefox, and some addons, but nothing that's native or current.

I think having history is incredibly useful short term, lets say a week or some days, but I don't think I have ever had to dig trough my old history for something. Usually what you need is to find some page you closed recently or something. And while I would like to use deleting history after closing browser, it interferes with stuff that I'm logged in, reopening tabs after closing etc. And ofc, it actually deletes history which is useful short term.

This is both request for help and improvement. It would be nice to have option on "clear history when firefox closes" settings, to delete any selected data older than set number of days for instance. Or if there already isn't, something similar in about:config.

I usually download and install manually the custom install of Firefox on Windows.

Recently, a new version was automatically installed without my permission and destroyed all my customization. THIS IS UNACCEPTABLE. I had to restore the older version from backup and I was going to stop updating.

But I see that the manual custom installation is still available for download.

I want to make sure that if I use it it will not wipe out my customization again.

Please confirm.

when i wanna open a page on youtube, i got some errors like below in my console window:
