I have reinstalled Firefox on my Mac many times, completely removed all files using app cleaner, and reset Firefox by holding shift and option on start. Despite this, the app is very slow to launch, and when it does no pages load or render. Opening a new tab freezes the entire app for 15-30 seconds, and when the tab opens it is completely blank. Attempting to browse to a URL does nothing, and the address bar just returns to being empty. Attempting to open settings does nothing, although parts of the app that open separate windows such as the about version info and bookmarks work fine. The only thing I haven't done at this point is completely reinstalling macOS, so maybe there is something wrong with my system config. I first noticed this issue when using the early macOS Sequoia betas, and assumed the app wasn't updated to support it yet. However after updating macOS and completely removing and reinstalling all traces of Firefox, it still doesn't work. I am currently using macOS 15.1 beta, however the issue also persisted on 15.0.

Hi, I have an HTML page - currently on the desktop PC - that contains a few graphics (they relate to IPA sounds) and a bit of javascript which will make the sounds play when the user mouses-over the graphic, and stop on mouse-out. The script uses <embed> tags. I know these arent favoured but I think they should still work, as they have in the past, so the script itself is fine. But there is no sound (obviously I have checked the src is correct and made sure the speakers are on and working. They are.) W10, FF ver 128.6.0esr (64-bit)

Since the last Firefox update, I am unable to sign into my Outlook account. When I click "Sign In" it opens a new tab with the sign-in buttons. Works fine in Edge and Chrome.

hey My name is Moji and i was 17 years user of firefox. my mozilla after last update became so slow when i open it and seems crash. my screen frizing for 3-4 mins and i dont know why? could you help me what can i do???? please answer my question to my new gmail : [email address]

Today I was no longer able to stream movies on Amazon Prime or Youtube. I watch Amazon movies most nights, watched last night. Tonight I got a message when I tried to continue watching a tv series on Amazon that I've watched for weeks. It said I had to update Firefox and told me how, but when I went thru the process Firefox said it was up to date. On Youtube I got an error msg. 99,999 . What is happening?

we have 2 imacs here:

imac A just had OS catalina installed and firefox is shown as up to date running v 115.15. However, while it loads the apple tv website the site remains unresponsive to input.

imac B is runnning OS Sonoma and firefox is shown as up to date running v 130.01. There is no problem with the apple tv site, which responds to input.

So: why can't I update firefox to the latest version on imac A and why is the apple tv website unresponsive when it works on imac B running an older OS?

Have an app with a web interface that I used for years, but not with several of the latest versions of FF. Chrome, Edge, and DuckDuckGo all show the page as expected and the page functions properly.

URL: http://127.0.0.1:8384/ Error looks like this:

Unable to connect

Firefox can’t establish a connection to the server at 127.0.0.1:[port number].

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

Have tried a large number of things including:

Ping works for ip and hostname, v4 and v6 Confirmed address is accessible through other browsers Disabled extensions Added exceptions in Settings for HTTPS-only mode Various settings in about:config, careful to return them to previous states when they didn't fix the problem Tried Safe Mode (aka Troubleshoot Mode) Refreshed Firefox (as prompted before uninstalling)

My last step is to reinstall, but thought I'd ask here first. Has anyone seen this before?

Why when you click on the extensions button (jigsaw puzzle icon) in the toolbar to open the extensions panel the “Personalize Your Firefox” screen appears ???

When you right click a gear icon in a particular extension, the drop down menu has no "pin to tool bar" option, it only shows "copy/select all/print..." options ???

Thnak you.

When I try to load "Comments" I get this message:

Failed loading comments! Please try again...

Trying again doesn't help.

This is a fairly recent problem

Thanks for your help.

Hello!

After the latest Firefox Desktop updates (not sure which one exactly, since I didn't notice the issue immediately), I've started experiencing a problem with copy-pasting text — specifically with line break formatting on Windows 10.

Instead of copying line breaks using the Windows-style carriage return + line feed (\r\n), Firefox now copies only line feeds (\n). As a result, the text appears as a single long line when pasted into native Windows applications — which breaks the expected formatting. This behavior mainly affects:

• Text editable fields (e.g., contenteditable or textarea) in modern web applications.
• Code blocks or snippets (such as in Markdown or monospace) copied using "Copy" buttons (e.g., in ChatGPT or GitHub).

At first, I noticed this only when copying code from ChatGPT using the code-snippet copy button. But now it happens in almost all editable text areas — if I enter text with line breaks manually, and then copy it, those breaks do not appear properly in native Windows apps. For example:

• In Google Sheets, I often edit text with line breaks in a cell, but when I copy it back, it's all flattened into one line.

Right now, I have to fix this using scripts that replace \n with \r\n, but that's a very inconvenient workaround.

❗My main question is: What changed in Firefox that caused this behavior? This used to be reliable and feels like a regression. It’s a very basic feature and critically important for my daily workflow!

🔧 Follow-up questions:

1. Can this be fixed in a future Firefox update? Will it be addressed?
2. Is there a way to fix or configure this behavior right now via browser(settings, configs)?
3. Is there an extension or workaround that can restore the \r\n format without manual scripting?

Affected apps:

• ChatGPT
• Google Spreadsheets
• Trello
• ProtonMail (regular text copying)
• (more)

Thanks in advance for any clarification or suggestions!

Hi, Nvidia RTX Video HDR and Super Resolution works fine when I open a link. But if I scroll the page it turn off. The video still play but the colors changes, I can see that RTX enhencement is then inactive on the nvidia panel. Sometime immediately sometimes after more scrolling. Same on Youtube and Twitch. Any Idea ?

This is a problem I only started experiencing yesterday, but if I try to upload an image to a website (such as social media), and I double-click a shortcut for a folder, it attempts to upload the shortcut as the selected file, instead of opening the folder.

This is only a problem with firefox, as I tried doing this in another browser and I was able to open it as a folder normally. Any ideas on what could be causing this or how to fix this?

Even though CPU and GPU utilization is very low during 8K60fps Youtube playback in the Firefox browser on my base M4 Mac mini, the struggles heavily to play this, drops tons of frames, and the video almost stops playing.

8K 30 fps is not problem, and since utilization is pretty low, that doesn't explain the poor performance.

So please optimize 8K60fps Youtube playback on all platforms in the safari browser, but especially on Apple SIlicon Macs.

So i use garuda linux(not sure if necessary but still telling). The ".mozilla" folder is about 134 GB! I have browsed it a bit and found a lot of this folders "vuzpdtyn.default-release-backup-crashrecovery", "tor50voj.default-backup-crashrecovery-", "profile-somestuff-backup-crashrecovery" Is it safe to delete the old ones from this?
