Diễn đàn hỗ trợ Firefox

i write an email and it automatically goes to the outbox,.... but it never is sent. my sense is that it's trying to send emails via another browser... not firefox and it just locks it up.

Youtube is nonfunctional on firefox as of April 29 2025. It was all working fine last night, then I woke up to no youtube. It loads the website as a blank screen. Videos can be accessed by going directly to their URL, but no recommendeds load in, no comments section, even the title and channel information is unavailable. I would say none of the buttons work, but there are no buttons to test. It works fine in Chrome still. I know it's not my extensions because I tried removing them all, and it didn't fix it. I know it's not my cache/cookies, because I cleared that too and it didn't fix it. I know it's not on Youtube's end, because it works fine in Chrome. I know it's not an update issue, because I updated my browser and it didn't fix it. Please. I want to be able to use youtube in firefox. Please help me fix this thing. I have attached photos, but I suspect they'll be more demonstrative of the problem than useful for troubleshooting.

I use Zen Browser, and since updating my MacBook to the latest OS, Seqouia, my Zen Browser iCloud Passwords extension doesn't work. I'm prompted to update my MacOS to Sonoma or newer, which I've, of course, done. I'm wondering if there is a workaround or if this is simply a bug that needs fixing.

Two days in a row I have not been able to get into my e-mail due to an error relating to the sign in to Bell services : webmail.bell.net. PR_CONNECT_RESET_ERROR comes up every time. A Bell employee managed to get it sorted briefly yesterday by resetting my password for this Bell service, but despite having embedded that new password into the incantation to get into the site supposedly, the error is happening again today! They cannot get back to me in less than 24 hours (and it may be 48) so my tax returns are definitely going to be late this year..... added to the usual problems of staff unable to speak comprehensible English, frustration is making me feel quite ill. Browser is Firefox and operating system Windows 11

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

After updating to v 133.0, when maximizing Firefox (not F11 fullscreen), a taskbar that is set to "auto-hide" will no longer unhide when mousing to the bottom of the screen. This did not occur with the previous version (132.0.2).

This behavior is also unaffected by the "devtools.toolbox.alwaysOnTop" setting in about:config as i've tried switching from the default "true" to "false".

Update: Still persists in 136.0.2

Здравствуйте. Что произошло с браузером. Почему не загружаются страницы, а открываются те, которые открывались когда-то раньше? Мне сейчас постоянно жать на кнопку обновить страницу? Что вы сделали с браузером???

something has happened in the last couple of weeks. I can no longer use firefox to get into sites with embedded information. I can't get into my Bank account or Energylink. I've been using firefox for years but I may have to switch if someone doesn't tell me how to fix this....

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!

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.

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'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!
