Firefox Support Forum

Hi!

I get repeated messages that I use an old version despite having downloaded the most recent version. When i try to start Firefox it won't start, I only get a message and the precise wording of the message is" You've launched an older version of Firefox Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox." Then I get two choices, either "Exit" or "Create New Profile". If I choose the first, I exit. If I choose the latter and create a new profile then I loose my bookmarks and browsing history. Appreciate any solution you might have

Why can't Firefox copy text to the clipboard anymore? It won't copy text from a web page, from a URL, or even from about:support "Copy text to clipboard"!!! I'm using version 1.22 64 bit on windows 11. I've reinstalled Firefox but it doesn't make a difference. I've tried "Troubleshoot Mode" and it's still broken!!!

I can paste into Firefox but something has broken copy!

The last update forced itself onto my laptop and since then my browser has been lagging and freezing constantly. For example, when I click to refresh a page it will take at least 30 seconds before it even starts loading the page again and then it still takes it a minute for the whole page.

So I just picked up a new laptop (ASUS Vivobook 16x), and everything is fresh on it. Additionally, this only affects some video content in Firefox, with Edge browser unaffected. In brief, what is happening is that within a couple hours of having the browser open, certain video content stops working, specifically Twitter/X videos just spin, YouTube previews stop working, and videos continually load. Netflix videos continue to work, but hover previews stop functioning. I even check the 'Stats for Nerds' on YT and it shows 0 KB network activity in Firefox.

I've tried every basic action I can think of:

• Turning off extensions (only use Ublock and Bitwarden)
• Browser Refresh (x3)
• Reverting from 120.1 to 120.0, and now 199.0.1
• Clearing the browser cache
• Reinstalling NVidia and Intel Drivers
• Running in Safe Mode

Only by doing a refresh or completely closing/opening the app gets videos to function again. This doesn't affect the old laptop or my desktop, which makes me think it's a rogue driver--but then why would Edge function without error over the same period of time?

Are there any settings to play with in the browser that can help diagnose?

Firefox uses too much memory, sometimes 20GB on a 32GB Windows machine. It's usually one or two threads which are hogging incredible amounts of memory. This time I had about 30 tabs open.

Today I tried Firefox about:memory "Minimize Memory Usage" several times, and it was largely ineffective.

I did a "create memory dump file" of one 5+GB bloated thread using task manager, but can't find a way to upload the compressed archive with this report for analysis. Finding a way to report this issue was quite a challenge. It seems most help avenues are now missing/moved, and other reports of this type of issue are "Archived".

I tried killing the 2 bloated Firefox threads and checked for tabs which might be missing or malfunctioning. Everything continued to run normally while more than 10GB of memory was returned to system use. Leaving these bloated threads overnight doesn't improve anything, in fact I can often get up and find my machine is completely out of memory because Firefox consumed it all. My smallest machines have 16GB RAM.

These memory issues aren't new. I've been reporting them off and on for more than a decade. They get better for a few months after reporting, then they get bad again in a few more months. The battle to get memory leaks fixed is continuous while Firefox springs more leaks.

I'd like to give you the memory image I generated so you'll at least have some real data to look at and analyze for this report.

The attached task manager snapshot image is a very minor example of this issue. The numbers keep increasing like there are one or more large memory leaks.

I am having a significant issue with firefox draining my battery. I used chrome up until the new year and then switched over to firefox from chrome. Overall I love firefox so much more. The format is way more pleasing. I love how it easily signs me back into everything, BUT IT DRAINS MY COMPUTER SO MUCH. Like i used to have an 8hour + battery span my laptop neverrr died. Now I get through MAX 2 hours of full use before needing to charge, and maybe 4 hours just having it at school but not using it.

I thought my dell suddenly started crashing, ran all these tests, and then I realized the only change was that I had started using Firefox... So sad I think I am going to have to leave it.

I read a lot of articles and did everything suggested. my graphics is webreader , i turned on all the suggested features, i have 2 extensions , the only thing I could maybe think of was that I use an animated theme so maybe that was killing the battery, but like if I can't use my theme than whats the point.

I play a game at Vegas World. It's basically a free online slot machine site. I have played it for years with Chrome. Recently switched to Firefox. Playing an auto spin slot game, Firefox gets slow and hangs after about 25 spins. Chrome will go for 10,000 spins. So, Firefox is useless on game sites. I don't really expect a fix or solution. And I don't actually expect to use Firefox by the end of the day.

Hello So to make long story short, since last 3 updates to Firefox i cant log in to my online bak account ,and yeah i can log to it on Chrome, windows shit show browser... so well .. can You fix it ? Or shall i just switch browser ? As everything have been working fine before, and i have been happy using You www browser till now...acctualy till i install Firefox update :P

When I try to watch a movie (on website flixhq.to) it gives me error code 232011 and then i change the server my subtitles don't work. I tried different websites but the same thing happens. I've done all the troubleshoot methods possible. I only have this problem on my laptop, when i use this website on my phone it works properly. I've never had a problem with this website before ,this all started beginning of this month. Someone please help me fix this!

Websites and their pages slow way down when I have Malwarebytes Browser Guard turned on. This only started a couple of months ago, I had no problems before then. Could this be an issue with the Malwarebytes browser guard or a Firefox update? Thanks for any help you can be, Larry

I want to use Firefox in Windows 10 but it is very glitchy and buggy whereas in Windows 11 it is fine.

I have Acer Nitro 5 AN515-57 Laptop with Latest Windows and Firefox updates!

Firefox displays weird characters in text when some pages are loaded. This appears to happen with Helvetica font and maybe some others. The problem seems to go away when firefox is launched in safe mode, and does not occur in other browsers. After a little digging I found when I turn hardware acceleration off the problem seems to fix itself. I'd rather not operate firefox with this option off, and I have a relatively new mac so this shouldn't be an issue. Is there a better way to solve this problem? Attached are pictures of the issue when hardware acceleration is on. As you can see, there are weird characters that display on the right.

while using the site https://animesuge.to/home and using any server other than filemoon, the audio will either play for split second and then mute, or it wont play at all. The video itself plays fine. i tried it using other browsers and it works fine, it only happens while using firefox. i tried turning off all extensions and running in troubleshoot mode but neither of these helped.
