Firefox 社群討論區

I was positively surprised recently when the new Firefox profile manager (about:profilemanager) was introduced. https://www.tech2geek.net/how-to-use-the-new-updated-profile-manager-in-firefox-2025/ is an article about that.

However, I thought it's just a new visual UI with an in-browser switcher for the existing profiles (that I already had setup). However, it does not appear so.

The differences I see:

1. 1. 1. old profile management

• was managed by `about:profiles` or when starting FIrefox with `-P`
• is saved in `~/firefox` and the `profiles.ini` clearly and quite obviously mentions them there, so it's easy to manage them.

I also found this old support article: https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles

1. 1. 1. new profile management

• automatically asks on startup if more than one profile exists
• is managed by `about:profilemanager` or with the Firefox burger menu
• seems to be saved in `~/.mozilla/firefox/Profile Groups` (Linux path here) in some .sqlite files, and I do not quite understand the format. Not mentioned in `profiles.ini`.
• also, when you change something here (even like opening a profile?), you cannot open `about:profiles` anymore, because it says "Some Firefox process has made changes to your profile, […] you need to restart Firefox", only after a restart further changes would be possible, which I find quite confusing but it also indicates somehow the features belong together?

And this seems to be the new one: https://support.mozilla.org/en-US/kb/profile-management#w_whats-the-difference-between-profiles-and-multi-account-containers

1. 1. Questions

• What are the differences here (I may have missed)?
• How can the new profile feature save so few files? Is it technically called "profile groups"?
• And the most important: How can I migrate an old profile? (In order to use the new features and GUI etc. I quite like)

Hmm. We’re having trouble finding that site.

We can’t connect to the server at fzttlwrt.r.us-east-1.awstrack.me.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

I'm setting up a new computer and trying to sync my old bookmarks. I have discovered I used a Google email address as my primary email, not my yahoo email. I can't seem to fix this.

My computer unexpectedly had to do a factory reset. I had to add Firefox back on to my computer. It was my main default browser. I couldn't remember my password because I had Firefox for so many years. Your system forced me to change my password and now I cannot gain access to my bookmarks/passwords when I sign on. If you tell me that those were lost in the transition, I will be so upset. This was the only reason I was using you and do not understand why syncing is not working or recovering the information. I hope that this can be recovered, if not I have no use for your browser and will switch to a more updated browser in Chrome. I have never had such problems and cannot even remember all the bookmarks I have lost. I will never forget this experience. My hope is it will be because someone there was able to save the day and not because I realized that your company is outdated and clunky like Microsoft. Hoping you can help and completely upset. I am also very confused why my information would not have backed up automatically.

I have lost all my Firefox bookmarks. All gone. I have searched online for solutions, and have seen what appears to be a standard procedure for doing so. Bookmarks>Manage Bookmarks> LIbrary>Import and Backup>Restore

This is where it breaks down for me......I see no date available to use. All I see is "Choose File" and when I click that, nothing happens. That is the dead end I am at now.

Can anyone out there point me in the right direction? Many thanks. Jay

Hello,

I work for a company that integrates with Netsuite via SSO. Users should not be required to reenter their credentials to access the integrated app via a NetSuite subtab. However, this has been an ongoing issue. I thought it had something to do with cookies, but I cannot figure out what is causing this. Here's what happens: A user logs in to Netsuite, looks up a posted document, and clicks on the subtab of the integrated application. They are then prompted to enter their credentials. This prompt keeps repeating whenever the user refreshes a page or opens a tab. It seems like the browser is not retaining or saving the user's credentials. This does not happen to Chrome or Edge users. Is there anything you can do?

Your assistance is greatly appreciated.

Regards, Mac

Is there anyplace that shows how to use what the new release says on the 146.0. I got the message below when viewing new options in 146.0, but going to settings, sync just wants me to sign in and do a cloud backup.

Doesn't sound like what is in message below that I got after updating to 146.0. From what I found looking around, you are suppose to go to setting, sync, click on backup and choose location. There is no option backup, just an option to sign on. Below is message I got when checking what is in update 146.0:

Windows 10 users can now automatically protect their passwords, bookmarks, and more by turning on backup in Firefox. Your browsing data is saved daily on your device and can be encrypted with a password When you set up a fresh install of Firefox on any operating system for a new device or your current one, you can restore from this backup and pick up right where you left off. This feature is currently available on Windows devices and will be coming to other operating systems soon.

When browsing on IMDb (see image attached) when I click on the "See All" button just above "Soundtrack" at the bottom of the image nothing happens. This should expand the list above it, in the case an actor's credits. I have NoScript 13.5.2 installed but all scripts are allowed here. I get this on all the IMDb pages.

I try to connect to a web site but I get this response:

"Secure Connection Failed An error occurred during a connection to help.wned.org. Cannot communicate securely with peer: no common encryption algorithm(s). Error code: SSL_ERROR_NO_CYPHER_OVERLAP

I’ve developed a Firefox extension similar to the RankingsFactor SEO Chrome Extension, which analyzes on-page SEO elements such as meta tags, headings, links, and canonical tags.

The core functionality works fine in Chrome, but when I ported it to Firefox using the WebExtensions API, I’m facing permission issues while trying to access or read the page content (DOM).

Here’s what I’m trying to do:

Inject a content script to read <meta> tags, headings, and links.

Display this extracted data inside my extension popup.

However, in Firefox, the script doesn’t seem to have proper access to the page DOM — even though I’ve included "permissions": ["activeTab", "tabs", "<all_urls>"] in manifest.json.

I’d like to know:

Are there any additional permissions required in Firefox to read page content?

Does Firefox handle activeTab or content_scripts differently than Chrome?

Is there a specific event or user action needed to grant temporary permissions?

Any help, code examples, or guidance on fixing these permission restrictions would be appreciated.

Сегодня обновил Mozilla FireFox до версии 146.0 (64-разрядный). После обновления в панели "закладки" (cntrl+B) появился ненужный мне цвет выделения только что открытой мною вкладки (смотри скриншот). Как поменять данный цвет на менее контрастный ? У меня включена "темная тема", цвет выделения - ядовито-голубой. Хочу изменить его на другой более мягкий цвет. Как это я могу сделать?

Today I updated Mozilla Firefox to version 146.0 (64-bit). After the update, the highlight color of the tab I just opened appeared in the bookmarks bar (Cntrl+B) in an unwanted way (see screenshot). How can I change this color to a less contrasting one? I have the "dark theme" enabled, and the highlight color is a bright blue. I want to change it to a softer color. How can I do this?

Hello

After a recent update, the bookmarks menu changed—when you click a certain line, it glows bright blue. I understand this is for ease of use while using bookmarks, but I'm used to leaving this menu open all the time, and after these changes, the blue glow is very distracting.

In light of this, I'd really like to know how to restore the old display, or, if that's not possible, I'd like to see special personalization settings for this type of thing in future updates.

I'm using W11 & Firefox/Mozilla 'Version 146.0 (64-bit)' in ‘Dark Theme’ - my sidebar bookmark in use is now 'highlighted in BRIGHT blue' which is VERY ANNOYING - can I get rid of this feature? Is there a way to adjust the highlight color/intensity? Please let me know. If there is no adjustment possible, please take care of this in your next version. Thanks, John

Dzień dobry, podczas wymuszonej przez was aktualizacji, znikneły mi wszystkie zakładki Mozilli Firefox z ostatnich 15 lat!!!!!! Prosze o zwrot, apropos to jest skandaliczne zachowanie waszych informatyków

Hello, for quite some time I have been encountering an issue where the scaling of browser elements gets broken when I unplug my Mac from its dock/external display and then being using Firefox using the built in Retina display. This only impacts Firefox and renders Firefox completely useless until I quite Firefox and reopen it. It impacts all open Firefox windows. The attached screenshot explains it better.

Firefox 146.0 (aarch64) MacBook Pro 16-inch, 2023 macOS 15.5 (24F74)

Any ideas?
