Go to about:config and type groups, it's being actively developed.

There's also another API that you can actually use if you're a developer in Browser Toolbox, enable Browser Toolbox and type gBrowser.addTabGroup, you can add tabs to group using this API, and if you find a way to append it to Tab Tray you should be able to create something like this image:

I know vimium works in firefox, however I ran into this 4 year issue: https://github.com/philc/vimium/issues/3674

Is there an alternative that doesn't have that issue?

I use a 14px bitmap font as part of my system theme. It is set to display at 14px in my gtk theme which works for tabs, bookmarks, right-click menus, and other parts of Firefox UI, but the Firefox address bar doesn't seem to be the same size and is blurry.

How do I change the font size of the address bar? Is there an element I can target in userChrome?

• Firefox Nightly 131 introduces vertical tabs and an improved sidebar, enhancing tab management and multitasking for users with many open tabs.
• The vertical tabs feature, similar to Microsoft Edge, keeps tabs organized on the left-hand side and can be customized via Firefox Labs settings.
• Additional features include AI chatbot integration in the sidebar and ongoing development of tab grouping and profile management tools.

Mozilla’s system only measures the success rate of ads—it doesn’t help companies target those ads—and it’s less susceptible to abuse, EFF’s Lena Cohen told @[email protected]. “It’s much more privacy-preserving than Google’s version of the same feature.”

Privacy experts say the new toggle is mostly harmless, but Firefox users saw it as a betrayal.

“They made this technology for advertisers, specifically,” says Jonah Aragon, founder of the Privacy Guides website. “There’s no direct benefit to the user in creating this. It’s software that only serves a party other than the user.”

Mozilla has a close relationship with Google, as most of Firefox's revenue comes from the agreement keeping Google as the browser's default search engine. However, the search giant is now officially a monopoly, and a future court decision could have an unprecedented impact on Mozilla's ability to keep things "business as usual."

United States District Judge Amit Mehta found Google guilty of building a monopolistic position in web search. The Mountain View corporation spent billions of dollars becoming the leading search provider for computing platforms and web browsers on PC and mobile devices.

Most of the $21 billion spent went to Apple in exchange for setting Google as the default search engine on iPhone, iPad, and Mac systems. The judge will now need to decide on a penalty for the company's actions, including the potential of forcing Google to stop payments to its search "partners completely," which could have dire consequences for smaller companies like Mozilla.

Its most recent financials show Mozilla gets $510 million out of its $593 million in total revenue from its Google partnership. This precarious financial position is a side effect of its deal with Alphabet, which made Google the search engine default for newer Firefox installations.

The open-source web browser has experienced a steady market share decline over the past few years. Meanwhile, Mozilla management was paid millions to develop a new "vision" of a theoretical future with AI chatbots. Mozilla Corporation, the wholly owned subsidiary of Mozilla Foundation managing Firefox development, could find itself in a severe struggle for revenue if Google's money suddenly dried up.

Hello all,

As you may be aware, Firefox introduced on-device translations on the desktop a few months ago and according to this knowledge base page it has been available since version 126, but unfortunately only on some unnamed devices.

Do you know of any way (i.e. preferences in about:config) to forcefully enable the feature?

Thanks in advance

PSA (?): just got this popup in Firefox when i was on an amazon product page. looked into it a bit because it seemed weird and it turns out if you click the big "yes, try it" button, you agree to mandatory binding arbitration with Fakespot and you waive your right to bring a class action lawsuit against them. this is awesome thank you so much mozilla very cool

So, Mozilla adds an AI review features for products you view using Firefox. Other than being very useless, it's T&C are as anti-consumer as it possibly can be. It's like mozilla saying directly "we don't care about your privacy".

I'm actually pissed. I and many other users on the forum got an email from Chris Hayes on this:

Hello,

This is a friendly email to make you aware that your personal email address is currently visible to the whole internet via Mozilla's Discourse forum. It will show up in Google Search results. The affected email is the one that this email was sent to.

Many users may not be aware that their email address is publicly visible and Mozilla has not done anything about it in the 4 years it has been known, so I've taken this into my own hands to inform you.

What can you do?

You can update your profile name to be something else (actually, profile name is completely optional, so you can leave it blank if you want).

Steps to update profile name:

1. If you search for "Mozilla Discourse forum" it should be one of the first results.
2. Login. (Top-right)
3. Click on your profile picture at the top right.
4. Then, click on your username, at the top of the dropdown menu.
5. Click on the "Preferences" button.
6. Change the "Name" field, and click "Save Changes".

How did this happen?

There's a misconfiguration with Mozilla's Discourse forum that when you sign up with your Firefox account, it will by default use your personal email address as your profile's public name.

This is not a new issue, and has been known since 2020. The Mozilla Discourse forum is not actively maintained by Mozilla, so this has yet to be fixed.

You are one of 4,630 other users impacted by this privacy issue. It impacts 19% of all forum users, and 28% of new users.

More information:

There's a Discourse discussion about this problem here: https://discourse.mozilla.org/t/email-is-displayed-by-default-for-the-new-account/92266

If you have connections to Mozilla, please help escalate this issue to the right people. This is a serious and long-standing privacy issue at an organization that should value "Privacy by default".

Sincerely,@chrisA fellow Mozillian

I am not Mozilla: This is not an official Mozilla email, I do not represent or work for Mozilla. This is an email from a fellow community member spreading awareness of this unaddressed privacy issue.

So we run VMware, and this morning I go and check a thing, and Firefox gives me an error.. connection insecure cert is invalid

No I don’t have the exact verbiage

But Edge and Chrome opened it just fine. Whisky Tango?

It was a rekeyed , and re installed the cert for an easy ish fix.

But I’m far more weirded out that FF slapped it down ; and the other two were like; Ja sure no problem…

??

I'm almost sorry to ask this, but does anyone have experience with Firefox on Linux taking a long time to open? I'm running Pop!_OS on a fairly modern machine. All other programs open pretty quickly, but Firefox seems to drag its feet on startup. Once it's open it's great, no problems with speed.

I have tried disabling extensions (ublock origin, sponsorblock, decentraleyes, i still don't care about cookies) and I have tried setting my default profile as one without any custom user.js (I have a profile with Arkenfox and one with Betterfox's user.js). Nothing I have done so far has seemed to make any difference, but Help->Troubleshoot Mode allows Firefox to open quickly, so there must be something that I can disable that is causing the issue... Any ideas? Thanks.

I'm doing a quick review of the Addons that I am using on my Windows PC. I've had a look at some of the previous posts to try to get an idea of where things are at

Currently I have the following Container related Addons but I think things have moved on a bit since I looked at this.

• Facebook Container
• Google Container
• Switch Container

This means that opening Facebook and Google automatically goes into relevant containers and using Switch I can create separate containers for Work, Banking etc.

I noticed that I'm not using Mozzilla's Multi-Account Containers

Ideally I'd like to be able to:

• Have Facebook and Google Open in their own containers
• Potentially open separate containers for different Google Accounts
• Allocate other domains to open by default in a specific container (e.g a list of Bank websites into a specific container) but be able to override that
• Have links from Thunderbird open in relevant containers

What are people using in terms of Container addons?

It's a short blog post, but essentially talks about a world beyond surveillance advertising.
