Firefox Support Forum

I cannot use, update, uninstall, refresh, or reinstall Firefox (and haven't for four or more years). I always get this message: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." But I have (obviously) shut down the computer entirely any number of times in all those years. What can I do? I will be taking college classes and Firefox is one of the few browsers that the college supports.

Browser is FF Nightly 112.0a, but this is probably a bug in stable FF, too. "Always ask you where to save files" is checked, in preferences. Like title says, the "last download location" is stored, and works for downloading files, and downloading a SINGLE item in Tools\Page Info\Media (Ctrl-I), but if multiple items are selected (in Page Info\Media), folder opened will always default to set location, instead of last download folder.

I recently purchased a dell refurbished computer, I set it up went and downloaded fire fox without any trouble. I restarted computer today and it would not accept password I called DiscountcomputerDepot.com help and they helped me to restart and they told me they would have to reinstall windows from computer. So I lost all my programs. when it restarted said would have to update windows. I have tried multiple locations and get this same message This download.mozilla.org page can’t be foundNo webpage was found for the web address: https://download.mozilla.org/?product=firefox-stub&os=win&lang=en-US&attribution_code=c291cmNlPShub3Qgc2V0KSZtZWRpdW09KGRpcmVjdCkmY2FtcGFpZ249KG5vdCBzZXQpJmNvbnRlbnQ9KG5vdCBzZXQpJmV4cGVyaW1lbnQ9KG5vdCBzZXQpJnZhcmlhdGlvbj0obm90IHNldCkmdWE9ZWRnZSZ2aXNpdF9pZD0obm90IHNldCk.&attribution_sig=c3e7484d24556be08270fa603b3ed24cad53bd6caaec3f9e3f355d5c37300daa HTTP ERROR 404 Please help ,I have only use firefox since I had a computer , about 25 years.

I have my saved login and password details from another browser in a CSV and would like to import them to Firefox. I initially did not have the 'Import from a File' option in the drop down menu of the Logins and Passwords tab. After following a guide that instructed to set signon.management.page.fileImport.enabled to true in the about:config page, the option appeared. However, the said option is unresponsive to any clicks. The drop down menu simply closes once the option is selected, without any other reaction.

I'm not sure if this is a related problem but I am also unable to use the Import Wizard that appears on performing Alt+F and choosing 'Import From Another Browser...' The Import Wizard window only appears with a message that says "No programs that contain bookmarks, history or password data could be found."

Firefox browser version: 103.0.2 (64-bit) OS: Ubuntu 22.04 (64-bit) Windowing System: Wayland

Funnily enough, the 'Browse..' button for adding images under this support question doesn't work either.

Firefox wasn't working well on a seldom-used laptop, and the update to 100.0.1 didn't go quite right, so I deleted the old version and (using the odious Edge) tried downloading a fresh copy of the software.

But then I get a message from "7-ZIP" that reads "Can not create temp folder archive"

I'm stuck. Advice?

I have just installed V.100 and have come across a small problem. I can't sign into 'The Canberra Times' site. The option to sign in is missing from their home page. It is there using MS Edge or Chrome and I can login to the site on those two browsers. This does not seem to be a problem with other websites that I have tried since the new version!

I can't even begin to imagine what might be going on with a situation like this! Thanks.

How does one specify which program opens a .zip file after it is downloaded?

Presently, the download functions properly, but when I click on the file, VLC media player opens; have no idea why; how can I specify 7-zip File Manager instead?

Thank you. Appreciate.

Trying to download nord vpn and is says "failed" tried to download a receipt for the purchase of above and it says "failed" the browser on Win 10 is set to save files to downloads

Every time I come across a file and click the link to either open or save the file, Firefox just downloads the file -- THEN it asks me if I want to open it or save it..? It's bugged and an obscene security threat if the browser is so easily willing to download files against my intention.

Before I'm asked, I have gone through the settings multiple times to ensure 'Always ask you where to save files' and 'Ask whether to open or save files" are checked. Behavior does not change according to settings.

Example 1. Click link for a PDF with the intention to open, read, and forget 2. Firefox automatically downloads the file to my download folder 3. Firefox prompts me if I want to save the file or open it

If I click 'open', the file stays in the saved location even though I don't want it to exist.

When I installed version 103 on Windows 10 yesterday, the Tabs, address panel row of icons and the onscreen bookmarks icons doubled in size pushing about half of them off screen. Can I get them back to the size the were?

I keep them on screen to facilitate use and work more effectively. Pushing them off screen reduces the effectiveness of Firefox for me. I spent too much time today trying to find options that would allow me to revert to the former format without uninstalling v.103 - without success.

HELP!!!!

Dear community,

As I use a few self-made unsigned add-ons, for several years now I have been using the Firefox unbranded builds on Linux with great joy. In the past these became available for download shortly after a regular Firefox was released. Lately though things have changed. The current latest release for unbranded is stalling at version 107. So it's getting further and further away from the official Firefox, which is at 109 at the time of writing.

Obviously I'm concerned my unbranded Firefox is not getting the same security updates any longer. I do realize there's alternatives for supporting unsigned add-ons. Running a Firefox nightly or developer-edition is something I'd want to avoid, so for me these aren't real alternatives. I've also tried tracking unbranded info on bugzilla.mozilla.org, but couldn't find anything relating to this 'lag'.

Where can I find more info on this topic? Are these unbranded builds being discontinuated?

Thanks for reading, keep well!

At some point every night, my Firefox (and only Firefox) reverts to version 111 from the latest version. This happens on 2 different Windows 11 machines.

I can only get Firefox to run again by running from command prompt with "-allow-downgrade" option and then updating again.

I usually don't notice until I launch Firefox the following morning and it gives me a message that the profile was created with an older version and to exit or create a new profile.

I've had Firefox open and then it reverts and it gives me a XULRunner error about the profile being used by an older version.

I don't have any special backup or restore software running and the physical files in my Firefox folder in c:\program files\mozilla firefox are being physically pushed to a prior version dated 3/21/2023.

On both machines, I've completely uninstalled and reinstalled and it's good for a day and then reverts.

No log entries for the reversion can be found. It's just back to a prior version.

I've never come across anything like this before and have scanned for any malware or other issue, but haven't found anything.

I would like to save my Firefox profile data into my computer as I would like to transfer the data to a different computer. Is there any solution to how to save it down?

Hi

If I click my way through https://www.mozilla.org/de/firefox/all/#product-desktop-release I get a different Link everytime. So as someon who wants to distribute Firefox on different PC's , I want to know: Are there any direct download links for the latest version? The best would be some links like Webex has for distribution (e.g. https://mozilla.org/firefox/windows/FirefoxInstaller.exe)

Thanks in advance Robin

I'm trying to move to Firefox from Microsoft Edge on Linux. When I go to import data from another browser Edge is not an option. I have a CSV file that I exported from Edge. How can I import this CSV file? I found something on reddit that said to change security.allow_eval_in_parent_process to true, but that no longer works. How can I get my passwords imported without having to install another browser and import to that and then import to firefox?

I have a problem with opening files: Mozilla keeps saving them and ignores temp folder. I tried to modify browser.download.improvements_to_download_panel in about:config, but nothing happened. Can anybody help me?

Anyone know if there is a way to import Google Chrome extensions into Firefox. I am moving over and want to make it easy. When I search all I get is bookmarks which I know how to do.

TIA!

Ron
