Firefox Community Forum

Hello, I am running win 7. Yes and Old computer. When the system is running slow I do a task manager to see what might be causing it.

I have noticed multiple Firefox processes running with 0 CPU usage. What are all those for and do I need them? Can I disable them?

On a separate issue I am getting this rendering error. This may be a Microsoft question, but I thought I'd ask. Error in rendering player Error Code: 400-404 Session Id: k6x4392p (Pls: 35a725dd-3aac-4813-8431-159ebc196c01)

Lastly I did contact support about uninstalling two Firefox programs. I deleted the one you said.

Thanks again for all the help, Irv

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.

Firefox has stopped obeying target="_blank"

Started a month or so ago.

Take a look at Firefox target="_blank" problem for details.

There is not a topic in the dropdown list that remotely addresses this issue so I just selected Performance and Connectivity for the hell of it.

I am seeing a new problem with the latest Firefox version 370.0.2 (aarch64).

When I try to load a link, Firefox seems to go into a sort of "spasm" with repeated attempts to load the link via multiple new web pages.

The link finally loads, however if the link is a login page I can get login failures due to multiple login attempts (e.g. Microsoft login fails authentication due to multiple attempts.)

Please can you help with this ASAP.

Many thanks AJ

When I open a website in Firefox, the page opens OK but there Wikipedia website also opens in the background. The icon appears on the top row to the left of the name of the website I opened. When I close Firefox, the Wikipedia site opens and I have to close that too. Every time. What is going on? How can I get rid of it? Thanks. Windows 11.

I thought it was an issue with my pc, but chrome does not have this issue and neither do other applications. I have tried clearing my cache and cookies as well as ensuring mozilla was using my computer performance settings as opposed to hardware acceleration. The attached images are a very small example of the issue. Typically, after clicking on the screen or pressing a button the text is corrected but often replaced with new text being "corrupted". Any help would be greatly appreciated.

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!

i can not load in to a game pet city 2 and when i try to load it is say that they can not load my game because of Firefox please help with this problem it has been months I've have been having this problem

I have two Firefox tabs open on my browser. Task manager shows 35 tabs using 897 MB of memory. How do I make this stop? And why are so many tabs running? I have cleared cache, cookies, etc.

I went to my favorite web site this morning (dpreview/forums) and when it displayed I must have accidentally clicked some Firefox thing because the page was then overlaid with a thin orange highlight with the word PICK on it. I tried moving the cursor off the page but it only changed which segments of the page were highlighted. So I clicked and the page was replaced by just the menu section of the page, apparently that was what was highlighted when I clicked.

Now, no matter what I do, when I try to go to that url only the menu is displayed, the normal list of forums is missing. I've restarted FF. I've rebooted. I've cleared cookies and cache. I've refreshed the page. Nothing helps. Other web sites are fine. I can't imagine what this is for. A diagnostic tool or accessibility thing perhaps.

Please help. I'm running latest FF on latest Win 11.

I'm experiencing an issue with the drag and drop functionality in my browser that's significantly affecting my workflow. Previous behavior:

I could drag any selected text to any area of the browser window to open a new search tab I could lightly drag links anywhere to open them in new tabs

Current behavior:

Now I must drag content specifically to the tab bar at the top to open new tabs This extra precision required is frustrating and slowing down my browsing

I haven't intentionally changed any settings, and this change happened suddenly. This functionality was extremely useful for me as I frequently need to open multiple tabs while researching. Has anyone else experienced this issue? Is this a new "feature" or a bug? Most importantly, does anyone know how to restore the previous drag and drop behavior? Thanks in advance for any help or suggestions!

I'm using Windows Live Mail 2012 (which yes is pretty old) and one of the problems manifests itself in Firefox so let me describe this, I'm asking here because I don't think Microsoft ever supports anything any more so yes I'm grasping at straws but here goes. If I click on an email preview in my email client it proceeds to try and open that content in an almost infinite set of windows. If instead I click on a web link in that content it proceeds to attempt to open an almost infinite number of tabs of copies of this content in Firefox, I'm not saying this is the fault of the browser but it's a weird problem. Finally if I try and open the website that I need to use to manage the memory usage of this limited memory cable provider email account, the website no longer processes that correctly either so after a short time I will run out of memory entirely and lose usage of the account so you can see why solving this is an urgent matter for me. (I already contacted the cable provider tech support and their considered opinion was I ought to pound sand since they no longer provide email accounts any more for anyone. I have a peculiar feeling that one possible answer involves doing complex editing in the Registry, I think I'd rather back out the update (although MSC wil probably just overwrite it again in 6 months anyway) but I guess either would be acceptable, I'm just wondering how come I'm the only person in the known universe who has seen this weird issue?

I keep getting a pop-up for"sign documents online" in my Firefox browser. Several others have reported the same. It overlays the browser content so I can't use Firefox at all. My only option seems to be to uninstall Firefox and use a different browser. Is there a fix?

I’m getting a drop-down from Firefox when I’m on Firefox that says “read and sign a documents without leaving Firefox“. It dropped down window covers a document that I want to print and I cannot access the print button as a result. The drop-down has no way of removing it or moving it. How can I get rid of this drop-down?
