If I have vertical tabs enabled, and tabs sidebar uncollapsed it will unexpectedly change to collapsed if I reorder a tab via drag and drop. See attached gif.

Firefox 143.0 (aarch64) MacOS Sequoia 15.6.1 (24G90)

I have unchecked picture in picture in settings, but this function still appears in YouTube and other video sites.

I know it can be removed in about:config but i prefer not to go there. What is the point of this setting if it doesn't work?

Tabs crashing seems to be becoming more frequent. Also I use an online forum when wanting to post a reply I cant see the options for Font size, colour, emoji's etc

I am using the system Linux, ARM architecture, and Firefox version 144 Nightly. Using a large number of GPUs can cause the browser to crash. What else do I need to provide? Attached is my crash information. And only the first time I can enter the page I want, and then I can't do it again

Bei Aufruf der folgenden Adresse https://kasvault.io/wallet?deviceType=usb erscheint Screen Shot 1. Bei einen Klick auf den grünen Button passiert nichts. Mit dem Microsoft Edge funktioniert es (siehe 2. Sreen Shot).

When you access the following address https://kasvault.io/wallet?deviceType=usb Screenshot 1 appears. Clicking the green button does nothing. It works with Microsoft Edge (see screenshot 2).

Hi, I wanted to reduce height of tabs and remove borders in file userChrome.css.

So far this works for height, but was wanting to know if a negative value can be used to reduce further, Also tried some code to remove radius but it didn't work. Remove radius for selected tab and also hover on tab.

/* REDUCE HEIGHT OF TABS (VERTICAL TABS) */ .tabbrowser-tab { min-height: var(--tab-min-height) !important; max-height: var(--tab-min-height) !important; }

Hello Mozilla Support Team,

I’m facing an issue where the contact number on my website is not visible when viewed in Firefox, while it displays correctly in other browsers like Chrome, Safari, and Edge.

My business is called Rama Rehab, a Rehabilitation Centre in Delhi, and it's crucial for visitors to see our phone number for inquiries and bookings. The number is embedded in the site header/footer (or contact section), but for some reason, Firefox either hides it or fails to render it correctly.

Website: https://www.ramarehab.com/ What I’ve tried:

Cleared browser cache

Disabled all extensions

Checked in Private Window

Ensured number is not blocked by content settings

Still, the issue persists. Could this be related to content blocking, font issues, CSS rendering, or any privacy-related settings in Firefox?

Please help me understand what might be causing this and how to resolve it.

Thanks in advance, Rama Rehab

I've used Slack every day for the past decade, and Firefox has been my primary browser for some time now. I've never had an issue with the two, but now, Firefox is reliably crashing every time I attempt to open Slack.

I've tried clearing my cache both broadly and specific to Slack, with neither producing results. Even tried deleting all cookies on Firefox, which was a bit of a pain, and it was no help.

I did read up on some people encountering a similar issue that could be fixed by deleting the Slack entry in "about:serviceworkers," but this did not help here.

The only extension I'm running is uBlock Origin, which I've been running for probably as long as I've been using Firefox, and that has never presented an issue before either.

Would appreciate any help or advice on the matter.

I seem to have installed the YouTube webapp on Firefox when I clicked 'add tab to taskbar' that's new in 143. It shows up as recently added program on Windows. When I go to find the origin it leads to Firefox.exe. I can't find a way to uninstall through the browser or on Windows. Does anyone know how?

I was installing the latest vwersion and the all of my pages disappeared , plus the is not even an app to get in. Please help ... everything was on Firefox, even my bank account and email.

I use Comcast e-mail. I can't print anything! But I have Mozilla as my server (?) browser (?) and can't get a letter to print out. I really want to access a Notepad or a Word Program to have a BLANK PAGE to write a letter to a doctor or some other person in a professional manner! Word used to come with Windows! I had to install Windows 11, but I don't like "Bing" and so I have Mozilla, which I like much better. Windows 11 is in the background! Sorry, this is confusing, moreso to ME!!!!! When I try to print a letter, I've been using the Comcast e-mail account, but anything I try to print gets "compromised" and causes overlays and no way to print out a letter!!!! I just spent $46 for a new black printer cartridge! And I need to type a letter to my doctor! Please give me some help and tell me how to install a FREE blank page. I do NOT need help writing. I like spell-check, but I am quite proficient at composing a letter. I just can't PRINT the darn thing! Thank you.

I am getting a Secure Connection Failed error on every webpage I try to visit. Even if a page manages to load it will revert back to the Error code: PR_END_OF_FILE_ERROR if I refresh. Other browsers are working fine. I tried troubleshoot mode and it's the same. I tried uninstall/reinstall, desktop restart and still the same. I haven't changed any settings on my mac.

HI,

I updated recently the Firefox installation on my Mac to 139.0.1. I noticed that I can no longer print from certain websites using Firefox. One example is from Alaskair, where I tried to print a ticket and it was just sitting there trying. I had no problem printing the same with Safari.

Is this a known problem? Any suggestion (other than just give up on Firefox and use Safari) for what to do about this?

Every time I update Firefox, new bugs cause annoying problems. That's why I usually not updating for a long time.

Thanks.

Hello everyone,

Is there any software that allows software developers to see what the CSS they are creating is doing in real time ?

Because I can't imagine they're doing it blindly. I see some CSS files that have hundreds, possibly thousands, of lines.

If there is software that helps them see immediately what their CSS is doing, can it be used to create extensions (add-ons) for Firefox ?

Thank you for your attention.

I have a 2020 model MacAir with M1 chip, running Sequoia 15.6.1 and Firefox 143.0. When I bookmark a website, I no longer get the option to select which Folder to save it in. I have to bookmark the site, then edit the bookmark in order to place it in the right folder. Is there a fix for this problem? I've tried several times searching on the Help and Support pages but don't see anything. Thank you!
