Yesterday, the Firefox quit working. Today my connection was verified by Fios and during the phone call, we tried Google Chrome (Yuck!) and it worked on the internet. I have downloaded the latest Firefox and it still does not work. Is there a problem with Firefox? Should I delete Firefox and reinstall?

I'm using Windows 10 and have just completely uninstalled and reinstalled Firefox.

PROBLEM: Using MS Office 2021, OUTLOOK, when I select "EMAIL LINK" I get two windows, the expected one with the email link in the body, and one much smaller that is blank.

The second smaller window is an extra and serves no purpose; except that I have to close it. After an hour with a senior Microsoft tech this morning, he said the problem with with Mozilla; that everything works normally (only one window opens!) - leaving Firefox/Mozilla as the source of the problem

I've completely uninstalled and reinstalled Firefox, clearing the cache, etc., etc. so I have nothing to attach. ALSO, when I tried to "Share Date," there was an error and I 've had to retype the above again. So, if you need more that the info I've given, please let me know.

Trying to connect to yahoo mail (currently.com) and keep getting error messages. All other websites on firefox work.

When I have firefox open for a while, not sure how long, the display starts to mess up on some pages. When I print those pages, the words are still messed up. One place is printing things form the Virginia Department of Taxation I-File. I do not like to close out of the browser every single day and with other browsers I do not have to. This is new and started this year. Not sure when. How do I fix this issue without having to restart the browser and close out of everything all the time?

I usually keep between 15-20-30 tabs open at a time and like to keep about 5-7 at the far left. Just lately Firefox has started automatically on its own shifting my tabs that were far left all the way to the end on the far right. It is always just one at a time and then sometime later another and another.

How do I fix this?

So anytime about a month ago, everytime I boot up my PC then first thing I do is double click on Firefox to open it and that worked fine until a month ago, now when I do it youll see the circle spin for 1 second and spot but Firefox doent open, no matter how many times I click on it, the only way Ive gotten it to work is that I have to restart my pc and try again until it eventually DOES open when I click on it, I usually have to restart 3-5 times before itll open.

Im wondering why that is and how to fix it? I havent done anything new to my PC since then, no new Firefox addons, also if there was a problem with Firefox itself then restarting should never make it open yet it eventually works after a few restarts. soooo i cant be Firefox right? Ive also tried refreshing firefox as well as going to add and remove programs and uninstalled it then reinstalled it the issue still remains, any way 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.

MY HOME PAGE, WHICH JUST HAPPENS TO BE ESPN.COM WILL NOT DISPLAY PROPERLY...DOESN'T MATTER HOW I TRY TO OPEN IT (USE HOME BUTTON OR ANY OTHER WAY), THE STRANGE THING I CAN'T UNDERSTAND IS HOW TO CORRECT AS THAT PAGE (WEBSITE) IS THE ONLY SITE THAT DOESN'T OPEN & DISPLAY PROPERLY...WHAT COULD BE THE PROBLEM? SEE ATTACHED SCREENSHOT!

When I open a "new page". . . there were four rows of my bookmarks. Many have disappeared for a second time. I'm glad you are aware of the problem but, PLEASE . . . just give me a quick and easy fix without page after page after page of rambling instructions.

Or, better yet: JUST FIX IT!!!!!

Thank you!

All of my bookmarks are gone as of a few weeks ago. I tried rebooting but it didn't work. I tried importing them from Edge and that won't work. I can't save new bookmarks either. I tried importing them from an HTML file and that also won't work. 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!

I followed your very helpful article and my bookmarks reappeared, but the error message is now showing up every couple of days.

Update: Several days later, this is still happening. I wish someone would please help.

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 uses too much memory, with 1 tab 1GB+, and with 4 tabs all 3GB+, this is not normal, the forum topic did not help, reinstalled and did not help, there are no more than 6 extensions, and they consume only 160mb.
