Firefox Support Forum

My laptop died but I have been able to rescue the SSD and turn it into a USB connected external drive. I can see all data from my old PC.

I have tried to copy all of my User, Local Apps Data Mozilla Profile data folders to my new Laptop but the data does not appear when I fire up Firefox on the new laptop.

The old laptop folder was c:\Users|Phil, the new laptop is C:\Users\Phill {setup of new PC added a second L to my name}

Is this an issue ?

FF would start to load but never completely finish so I forgot & stupidly did the troubleshooting mode or w/e that put me back to default so LOST all my settings, etc.. Strangely it's back "close" to normal except I was using Passbrow which the icon shows on toolbar but greyed out & I can't get it to turn back on. I have the "Old FF Data" folder but following the steps it doesn't show where profile is stored for me to be able to copy the old data TO. IF I can restore the old profile hopefully that would get it back working ALL as it was...but HOW??

I download a file. It stops and speaks of a security risk. The website is https, but the file is http. Is there a location I can pre-approve all files from the url to override the objection? Thanks.

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.

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 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.

Where can I get Firefox 52.9.0? There was a list of old versions here but now I can't find it. I found https://download2.portableapps.com/portableapps/FirefoxPortableLegacy52/FirefoxPortableLegacy52_52.9.0_English.paf.exe I really did not want the portable version but avast considers it a threat so it may not be genuine.

Windows 10, Firefox will not load URLs or settings page. Uninstalled Firefox and downloaded a new copy. Upon install system error message attached appeared but browser appeared with all my bookmarks and loading error message (attached with bookmarks erased). New pages will not load.

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.

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.

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!

Why has this started up again? Pdf files are automatically downloading to my computer when all I want to do is look at the file. So many files that now need to be trashed after looking at them. This problem has happened in the past, but was resolved, only now I am finding it happen again. I do not want to have files saved unless I want to save them, not Firefox deciding that any file I open should be saved. I have Windows 11 & Firefox Version 113.0.1. Is there a way to revert to an older version of Firefox?

Firefox 112 update will not download completely. It just keeps saying it is downloading but it does not complete. I can't access some websites now since I have been trying to download the update. Please help. Thanks.

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!!!!

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?

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
