Firefox Support Forum

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.

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

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.

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!

I have a macbook pro running Sonoma 14.2.1. A few days ago I noticed the computer didn't update to the current version of Firefox when I attempted to do so after being prompted that an update was available. I went to "About Firefox" and saw the error message "Failed to check for updates". Please help. Thanks.

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.

A few hours ago, I had a problem logging in to pCloud. I didn't have any problems until recently, but now I get the following message: Secure Connection Failed

An error occurred during a connection to my.pcloud.com.

    The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
    Please contact the website owners to inform them of this problem.

How do I resolve this situation and continue using pCload through Firefox?

Suddenly when I try to go on Youtube, I get messages that I'm blocking ads. I'm on a Mac-mini using X El Capitan V10.11.6, which is the highest I can upgrade to. I'm using Firefox Browser 78.15 (64-bit) and info shows it's up to date. My old Safari browser still will work with Youtube, but Foxfire is my go-to browser.

Hello there,

I am having trouble getting to any website. I am using the proxy pac file which is set systemically, every other browser like Chrome, Edge, Safari work fine, only Firefox has trouble opening anything.

Hi, I have just returned from China. I use a Macbook Pro and am operating Firefox 118.0.2 (64-bit) I now find that when I use Firefox to access websites blocked in China (i.e google, the Guardian) I get a "Did Not Connect: Potential Security Issue" message. I can access everything with a VPN active I also got this for Microsoft Edge but the problem resolved by clearing cookies (didn't work for firefox) How can I fix this
