Forum d’assistance Firefox

When I try to download a file, the download always fails. This happens no matter what website I'm downloading the file from (see screenshot 1).

This started happening within the last week or so. We are running versions 97 and above.

Firefox is configured to always ask where to save files to (see screenshot 2).

Write permissions to the user's Downloads folder is denied for reasons unrelated to this issue (see screenshot 3). When I re-enable write permissions, the problem goes away.

Has anyone else run into this problem? Is write access to the Downloads folder required now, even if Firefox is not configured to save files to that location? Thanks!

I've had a problem recently with some sites (such as support.apple.com, but also others) loading very slowly or not loading at all.

• Restarting Firefox fixes it for a short while
• I've tried changing to No Proxy from Use System Proxy Settings - this, like restarting, helped for a short while
• Unchecking DNS over HTTPS: DID resolve the problem but I'm curious as to why. I enable it with Safari with no problem.

Firefox is becoming more and more buggy and more unstable using more than 8Gb of ram in either the apps processes or if not there then in the background processes and when you look into the firefox task manager it reports it is using no more than maybe 100 MB of ram the only way to stop it is to close the one process that is using all the memory. when i investigate using the about:memory function it tries to tell me that it is an extension using the memory but if i disable the 2 extensions i use and reload the measure memory it still is using exactly the same amount of memory. is there any sort of fix for this because i am getting sick of having to have the windows task manager open to close the rogue process every time i use my browser

For a few days now, I have not been able to play videos. I get this message in the video screen: "If playback doesn’t begin shortly, try restarting your device." When I opened Firefox in Troubleshooting mode, the video played OK and then when I stopped Troubleshooting mode the videos continued to play OK. However, on the next day the problem reappears. What's going on? Thanks in anticipation, Frank

I recently made the switch to Firefox. I attempted to use the version downloaded from the internet, which I already had installed for a long time, but it would not open. I then used the version available on the Microsoft Store, which worked fine. Eventually, Firefox crashed and would not reopen. A message saying something along the lines of "Are you sure you want to start Firefox in safe mode?" would appear for a split second, and then close. I tried:

-Starting Firefox in safe mode, but nothing happened. -Restarting my computer. -Reinstalling Firefox. -Running as administrator. -Checking it is not blocked by antivirus. -Using the profile manager to create a new profile: The .zip file version opens but does not help, and the version opened by using the "firefox.exe -P" command in Run suffers from the same problem as the browser and opens for only a split second. -Attempting to boot my computer in safe mode with networking, however, the Microsoft Store listed Firefox as uninstalled, and the network menu would not display any networks so I could not reinstall it. -Searching for any Comodo iseguard.dll files, but I found none.

The only thing that worked was searching "Mozilla" in files and deleting everything except what my computer said was part of the system. After that, I was able to open Firefox, but after a short amount of time, the problem started all over. I have no clue what to do and looking all over for solutions is driving me nuts! Please help!

I seem to have gotten something called Google Ad Services. It frequently interferes with my getting to websites and I cannot find how to block it or remove it. HELP!

Hi......,

I have had firefox browser for a while now and it has always worked fine. Now I`m suffering from that internet pages can`t be loaded ( see attachment ). I think,am not sure since the last update. The weird thing is that youtube does work and can just play video`s also 4K. I have read the error report but can`t really do much with it. Is there anyone who can help me in the right direction?

Thanks in advance for the trouble.

I've always used Firefox browser instead of Microsoft Edge, and I would like to continue using Firefox. However, it will not run in its current form under Windows 11. Does Mozilla plan to keep it compatible with Windows? I would like to keep using Firefox.

I don't need any images, you know the problems ... Freezes, no internet access.

Just got a new laptop with Windows 11, installed Firefox, and am running FF 98.0.1. When scrolling on some pages, the buttons look like they're constantly flashing. But if I scroll slowly, I can see that the button color is itself scrolling within the button boundary. Or at least, that's what it looks like. Attached a sequence of images to show what I mean. Can anyone help? It's so irritating that I might be forced to use a different browser, which I don't want to do! This didn't happen on my old laptop running Window 10.

Hi everyone,

Up until the latest FF release, opening an .ics (calendar file) link defaulted to the OS's preferred application; in my case Outlook. Now, every time I click on an .ics link FF asks where I want to save the file. I schedule ZOOM meetings all day and heavily rely on this feature.

I tried looking in FF's Files and Applications section in settings and .ics is not even listed as a file extension. I don't know how to add it.

Any assistance is greatly appreciated.

Just now, after a massive and catastrophic SUPER-MELTDOWN-crash that arbitrarily decided to absolutely murder my day, ALL my tabs and windows and ALL history of "Recently Closed" tabs and windows is gone!

THIS IS COMPLETELY UNACCEPTABLE!

What is the reason for the existence of a SYNC feature if it isn't to MAKE SURE that a record of open tabs and windows is SECURELY maintained no matter how many times the application crashes, so that AT ALL TIMES, this information is kept INTACT, regardless of the state of the end users device? That is BY FAR the most important part of the sync feature! Are you telling me that there is no backup process of that information?

This is the kind of thing I never expected from you guys at Mozilla. I've been using Firefox for MANY years because I trust what you do. Today that trust has been SEVERELY and BRUTALLY wounded, most likely beyond repair...

I need you to fix this...

I need you to recover that information for me and I need you to make sure that what just happened could never, ever happen again unless God himself caused every digital storage unit on earth to disintegrate.

The Firefox prefs.js file was quarantined by avast yesterday. Message indicated malware had infected the file. Now when I click on the Firefox icon the MSN browser comes up. How can I get back to using Firefox safely? Can I uninstall Firefox, then re-install it to make the problem go away?

I have an Airris modem router combo that is locked out for to many attempts. I have done a reset and it still wont unlock. I had the same problem wit a bank lockout on your website and i got out of it by accident when I found a security site on fire fox an it was in Preferences and it was listed as do not allow and allow, clicked on allow and that whole mes cleared instantly. did I write this down, no I will remember it SURE . cold you please tell me where it is

Is there any to make Firefox automatically restart a new session (loading the start page) after a crash, without any prompts?

Context: This is for a disabled person who cannot use input devices: I start her computer every morning before going to work and load a long Youtube playlist of videos, so she doesn't have to do anything. But if Firefox crashes 5 minutes after I left, she cannot restart anything herself and has to wait until I come back.

Any ideas?

Hi.

Using Windows 10. Suddenly, Mozilla gives the "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window" message. I've tried all steps listed on the help site except reinstalling Windows 10, as the comment made said this would require reinstalling programs that did not come pre-installed on my PC, which I don't want to do if possible. I have uninstalled Mozilla, and the install stalls at about 70% with the aforementioned error message. Any help would be greatly appreciated! Thanks.

I have this box that shows up over the top of any video application on my firefox browser since my most recent update. It doesn't appear on other browsers. How can I remove it?

Hello,

I have been using Firefox for something specific for a long time now. I've noticed in a recent update having the ability to do what I need has ceased. If a Firefox window is covering another (or covered by another program) on the screen, the graphics of the background Firefox window no longer update. I run a software that needs to see these graphics in order to function properly.

Could you tell me which version this stopped working and if there are plans to reverse whatever change you made?

Thanks, Kyle
