Hi!

When Firefox 96.0 rolled out on my machine, I was surprised to see my old Firefox Quantum theme default to dark. I did not enjoy this new behavior, so I tried to downgrade to 95.0.2. After installing it, Firefox told me it couldn't load the user profile, as it was used on a newer version of Firefox.

I have no idea where exactly I read this, but some website contained an instruction to erase compatibility.ini and that would allow me to use the profile on older versions. Tried that and it actually worked. I did notice that, when Firefox tried to update, it would say it failed. I was hoping that, once I find a solution to the forced dark mode and I update Firefox, the problem would go away.

Fast forward a few weeks, I found AutoConfig and browser.theme.toolbar-theme option in about:config. So I updated Firefox manually and applied AutoConfig and my original problem was gone.

Fast forward more weeks, there is another update for Firefox. And Firefox was still unable to automatically update. So I tried reconstructing compatibility.ini, which I did fully. But Firefox still won't update.

At this point, it's been like 3 months with a crippled user profile and I must say I'm tired of updating Firefox manually.

Is there any way I can fix this profile? If not, what exactly should I copy over so all my preferences, cookies, addons and themes get carried over to a new one?

I'm using Firefox 78.0.2 and i keep getting notices to upgrade. But the last time I upgraded, Firefox changed the locations of my tabs from below the address bar to above the address bar and also changed the behavior of the address bar. It took me a couple of weeks to find the answers and get things back the way they were. I don't want to upgrade Firefox because I have no idea what it might change this time. Is there a way to keep Firefox from sending me upgrade notices when I don't want them?

Dear Mozilla Community,

I was browsing on the Internet, when Firefox showed up a download window for f.txt. I then clicked away that window. I could not find a f.txt and my antivirus did not complain. If someone could tell me what this is it would be very kind. Also what I should do next.

I have a customers dead laptop, she wants her firefox profile copied to her new laptop.

Since the laptop is dead, I can't use sync. I have her profile data, which is useless in her new laptop.

For future reference, how am I supposed to do this? I've always kept as many customers as I can on firefox.

Is there a conversion tool? A way around this? Or am I just going to have to say shes out of luck?

I have a windows 10 laptop with firefox as the default browser. I do not like windows 10 photos, so I downloaded a older copy of windows photo gallery which I am used to and prefer. This has been working fine until recently. Now firefox saves images to windows 10 photos. I made sure to make photo gallery the default app for all images (jpegs etc.) but it still saves them to windows 10 photos.

Hello, I always download mp3 files inside webs using "Save as" and ".mp3" method. Sometimes I had to explicitly save filename with ".mp3" extension to force audio download. However trying to download an audio no matter what format I write in file always download only webpage as .html never as .mp3. Looking at sourcecode (image attached) I found a detail containing "chrome" in webpage. Later, I tried downloading with Chromium at it worked properly. Does anyone know how to download this from Firefox?

Thanks in advance for your help. P.D. I am using Firefox 84.0.2 (64-bit) for Ubuntu canonical - 1.0.

Used to be able to download files from anywhere I chose. Now, cannot download from www.bluesound.com. ISP and I ran test that shows download and upload work, and AT&T e-mails are arriving into MS Outlook (although very much slower than in the past).

When download request sent to Bluesound, the wait cursor spins indefinitely. Once left it running overnight, still spinning the next morning.

Perhaps this has to do with security settings. Advice, anyone?

I really miss the ability to have a "Save As" choice when i download pdf's or pictures from the web I'm always on the latest version of Firefox but only gets 'Open', Open with' and 'Save'...

Often the downloaded files gets lost in the wrong folder or hide itself with a crazy name that 'the web page' has given it.

AS both Google Chrome and Windows Edge offers that possibility and has for long, please include that feature in the next update...??

Thank You

I have 88.0.1 installed in c:/program_files/mozilla and in users/myname/appdata/local/mozilla. Don't know how that happened but how do I resolve this. When I go into Win 10 apps to delete the installations and order a new one for custom install, I am not given an option to remove, only to refresh. And also one installation shows in Win 10, not two. The exe files are in both these locations. I understand the profiles are in the appdata area, so it seems I need to delete the files in the other location, somehow.

Due to switching to a Linux distro with a slightly older version of Firefox, Firefox is complaining about the profile I copied in. The profile's compatibility.ini file says LastVersion=91.0.20210812023606/20210812023606. The current Firefox version is 90.0.2. Has the structure of the profile changed between these versions? If not, what's the best way to alter compatibility.ini?

The Firefox on my PC abruptly stopped working for pretty much no discernable reason and I don't know what to do. I've tried restarting the PC, uninstalling and reinstalling Firefox and nothing.

I dont get an error message. It just...doesn't start. If I reinstall it, I'm able to get the browser pulled up but then nothing on it works. It won't take me to any websites, it won't open the settings, it won't do anything. Refreshing the browser doesn't work either.

Failing that, I hopped on my phone and attempted to troubleshoot using information on this very site. I discovered that the problem might be stemming from corrupted profile data. I attempted to load the profile manager from Windows using command prompts...but that command doesn't do anything either.

I attempted to find the profile data on my computer and delete it...didn't work. I tried to reinstall Firefox to have it generate new browser data and that didn't work either. I dont know what to do and I dont know I'm supposed to fix this.

Please help, thank you in advance.

Installed flatpak and repositories but when I try to use flatpak to install firefox I get "No remote refs found similar to ‘firefox’".

I have tried following a few other ways to get it installed, such as using sudo and using sudo su but that has not worked at all.

I followed to flatpak quick setup on Chromebook guide that is linked in the above help article and created the nested containers in crosh as well.

below is what happens if I go to flathub and copy-paste their recommended command to install firefox.

I am using Firefox Nightly. It receives updates every day, but most of the time I cannot restart Firefox as soon as update is available. I want to delay it till next natural restart (ex.: night), however, Firefox shows notification about the available update. It's a minor issue, but seeing notification every day and having it to close every time gets annoying very quickly. I want to disable update notification but keep automatic updates. How can I do this?

I'm getting Profile Missing: Your Firefox profile cannot be loaded. It may be missing or inaccessible.

I don't have a caches folder I can remove the contents of the application support folder and nothing changes.

When I go to open the profile manager I get:

MyName$ /Applications/Firefox.app/Contents/MacOS/firefox-bin -P Error: Access was denied while trying to open files in your profile directory.

      1. !!! [Parent][RunMessage] Error: Channel closing: too late to send/recv, messages will be lost

I tried running Disk Utility but it froze the machine as it's a time machine disk and that slows it down immeasurably.

What's my next option?

Hello,

The sites of my bank and from the town administration made notes that my Firefox browser was old and should be updated. I downloaded from the Mozzilla site the new Firefox for Windows 10, uninstalled Firefox and installed the new one. Then again these sites noted that my browser was old. Again I uninstalled Firefox completely and then I found out that ALL the files were not deleted but some kind of hidden. In Windows Verkenner there were no files to be found but my firewall found them all, but they had no size, no date, no digital signature at all.

Then I deceded to do a test. In the firewall I switched all the rights of the "deleted" files into "forbidden access". Then again made a new installation with the new installation file. It proceded as normal. But then it apeared that again the same old version of Firefox was present again.

My question is: what is happening here.

Best wishes and thank you, Han Benes
