Firefox Community Forum

I switched to Firefox a few months ago and I've been using the "about:profiles" page to mimic chrome's profile feature. I have 3 profiles, each with their own Mozilla account. How can I migrate these to the new profiles system?

This afternoon, I clicked on a link from an email and for the first time got a choose a profile pop-up. I do not want this; I have read info on Mozilla and elsewhere about its purpose but it doesn't say how to just stop the pop-up - there should be an option just stop the pop-up because I don;t want to have to choose amongst options. I have started copy-pasting the links in emails and going to Chrome and will seriously have to reconsider using Firefox of this continues. I don't want to have to type about:config or anything - this should have been an opt out or opt in thing and I want out. Thank you for your help.

I have used Firefox for years, both out of conviction and to help protect my privacy, even though I often put up with images and forms not displaying on web pages.

Then, three times in two months, after restarting Firefox, I found all my tabs, bookmarks and browser history had disappeared. The only thing I did between restarts was to run Wise Care 365 to clear some space on my laptop, something I had done hundreds of times before.

The first time the loss occurred I found I had a new profile, a feature I neither wanted nor was consulted about. At least I was able to get back to my original profile. The next two times this proved impossible.

Firefox "support" was of no use. Multiple searches produced nothing which helped. After agonising hours, I was able to retrieve my bookmarks and my Firefox browser history through Microsoft Edge. But as a writer and (award-winning) journalist I cannot afford to risk losing my research and links.

So although I disapprove of some Microsoft business practices. I am moving to Edge. If I have missed something that makes sense of this, I would be pleased to hear it. In the meantime, Mozilla needs to improve its product and customer service.

Wishing its customers well,

For roughly three months I have been experiencing issues with Twitch.tv that I do not have on other browsers. Namely, after a random period of time the site will just "go out" on me. I can keep watching streams that are open, but any attempt to open a new window or tab results in a page with no elements loaded. During this "out" period none of my chats will send, and any other attempts to interact with Twitch will fail. After a random period of time, things will go back to normal.

I've tried clearing my cache and cookies, I've tried disabling and uninstalling all of my extensions, I've tried updating the browser, I've uninstalling and reinstalling Firefox, I've tried Incognito Mode, I've tried a DNS flush, I've refreshed Firefox and it didn't work.

I have found one thing that has worked though. I created two new profiles. The first had the issues occur again, but the second one hasn't experienced any of the same issues as far as I've seen, so I think the issue is with my settings. The trouble is, I don't know which setting is the issue, and deleting prefs.js doesn't appear to reset my settings, even after restarting my browser. Is there some step I'm missing regarding deleting prefs.js?

Please do NOT suggest using Firefox Refresh, as I am NOT interested in going through all the steps again, especially when it didn't work at all the first time I tried.

I am currently using FF v133.0 and I want to downgrade to v130.0. I tried this once before and could not get the 'Profile' to activate and reinstall all of my settings, bookmarks, add-ons, etc.

Please provide step-by-step instructions for doing this. Any assistance will be greatly appreciated.

I am using Windows 10 64 bit.

Thank you.

Is there an application to get rid of 'Old Firefox Data' folder? I tried to remove it once on another machine and i lost all internet connection (needed a full Windows restore) so very nervous about this.

Why is my browser stating that it is managed by my organisation.

I have never used it fr work and it is my personal laptop. Please kindly provide steps to remove this

I'm running Firefox 122.0.1 on a Windows 10 desktop PC, with a profile which includes a userChrome.css file which makes several layout and cosmetic changes.

I also have a laptop (also Windows 10) which has an old Firefox 97.0.1 installation, and I'd like to make the same changes on this machine which I'm used to on the main computer. I copied my desktop profile to the laptop, to the same directory as its present profile, but when I rebooted Firefox the transferred profile wasn't recognised.

While doing the transfer I received error messages about some of the folders: Destination path too long. This despite the fact that the registry flag to accept extended paths is set to 1. I had to skip several folders in order to complete the transfer.

Could this be the reason why the new profile isn't being picked up? Or is it because the two Firefoxes are of different versions?

I'd be grateful for any thoughts. Many thanks.

Can you add a configuration setting to Mozilla Firefox to disable Create New Profile, configurable in the policies.json file? (A second option but a much uglier one would be to disable being able to select a file location for a new profile. Then you could make the default profile directory write only, which would also accomplish the same thing.) (A third option would be to able to configure extensions by default upon installation in the ExtensionSettings policy.)

To explain, I use LeechblockNG on Firefox on Ubuntu. Very helpful. By placing a policies.json file (see at bottom) in /etc/firefox/policies/ directory, I can create a system wide policy. I can make the LeechblockNG extension mandatory and to be installed upon every new profile creation. That all works very well. HOWEVER, there is NO way to be able to set those options in the new profile. So LeechblockNG is installed with default options (which are no blocking at all), which effectively bypasses the addon.

I am also writing the author of the leechblock extension to see if there is any way to set the options for leechblock upon installation (the third option above).

But I know other people have this same question, and at present, if I am correct, there is no way to block new profile creation, or the Profile Manager window in Firefox.

So could you please add that option to the Firefox policies.json configuration? Something like "DisableNewProfiles": true would do it.

Thanks!

My current policies.json file in /etc/firefox/policies/ directory: { "policies": { "BlockAboutConfig": true, "BlockAboutProfiles": true, "PrivateBrowsingModeAvailability": 1, "DisableSafeMode": true, "ExtensionSettings":{ "*": { "installation_mode": "blocked", "blocked_install_message": "Prohibited install more extensions." }, "leechblockng@proginosko.com": { "installation_mode": "force_installed", "install_url": "https://addons.mozilla.org/firefox/downloads/file/4374316/leechblock_ng-1.6.6.xpi" } } } }

I have an account with Chewy. When I try to access the link to "My Pet" I receive this message:

400 Bad request Your browser sent an invalid request.

I don't understand why or how to correct it.

My account was probably hacked. I noticed this from an email I received from Mozilla. My account was logged in from Africa, which i noticed from the timezone because the email gives literally no detail. I logged into my account to kick them out but i found out i couldnt because the button didnt work. All the other kick buttons worked except the hackers. Mozilla has done nothing other than to email me.

when I start firefox, it tells me the old one is running and to close it. i hit the close button and keep getting the same message. I have uninstalled firefox and reinstalled it and keep getting the same problem.

I am a heavy Firefox user, and have been using it (and its predecessor) since Netscape. In the last year, the size of my Firefox profile has more than doubled, from 500MB to 1.3GB. What's the probable cause(s), and what can I do about it?
