I rarely turn my laptop off, when I'm not using it I put it into sleep mode. Firefox absolutely hates this though, and after a few days it will slow to a torturous crawl. Everything becomes horribly irresponsive, feels like nails on a chalkboard. It can even get to the point where it will randomly delay my cursor in Windows 10 itself by 10 SECONDS along with some bleed into other programs while switching between them. Fully closing Firefox then re-opening it will reset the issue, starting the timer again, but I hate doing this because I have doing that set to log me out of various sites which I then have to re login to, letting the torture boil until I give in. This has been my Firefox experience on laptop for at least 5 years now. Other forks of Firefox have this same issue.

I am leaving Firefox in the torture state currently to troubleshoot here. Currently the memory usage on Firefox is 6GB at 54% of my total ram, which is being used at 84% total. Total CPU usage is 23%. Wrote this on my desktop for my sanity so that's why there's no troubleshooting information.

I use Brave, Firefox, Firefox Developer Edition and Thunderbird. Brave: 600mb Firefox Dev: 600mb Thunderbird: 200mb Firefox: 800mb Why is Firefox using too much memory? Especially as I am running Firefox Dev as a direct comparison. I don't have any plugins on Firefox. Firefox Dev has uBlock Origin alone. Brave has a few plugins.

There have been numerous times when I click on a video to play (NY Times, WSJ, Universal Class), I just get a spinning circle but no video. Yet when I go on Google Chrome, the video plays right away. What's the problem here?

Thank you.

If it ain't broke, don't fi(o)x it. Never try to be too clever. I cannot log out of OUTLOOK.COM, then after goodness knows hot long, it says that I have been kicked out and need to login again. CRAP!!!!!!!

Duck duck search via Firefox has become painfully slow, although if Google search is used the speed is OK. I have cleared caches, cookies etc without any improvement. Firefox 148.0.2, Windows10. Is this a recognised current problem?

There used to be a much more useful interface for clearing specific browsing data (the landscape-oriented one). The new interface is far less detailed to the point of strictly limiting its functionality. There used to be a config setting ("privacy.sanitize.useOldClearHistoryDialog") that could toggle which interface to use, but as of an update in the last week (I've been away without a computer for a while), that toggle does nothing. Is there any other setting that can make this feature actually useful again?

Hello Community,

I have been experiencing significant issues with Firefox for the past couple of months. The main concern is high CPU and RAM consumption during video playback, especially on YouTube.

This issue started appearing only for the past month or two; it was never present before on the same system, and no significant hardware changes have been made.

Crucially, this problem is exclusive to Firefox. I have tested video playback on other browsers such as Google Chrome, Brave, and Microsoft Edge, and do not face any similar performance issues with them.

Your assistance in resolving this is greatly appreciated.

Thank you.

Hello Folks, I just importeda a new certificate. Then I wanted to save all my certificates for backup. Selecting "Backup all...", I neter a secure password and click ok just to get the following error message: Failed to create the PKCS #12 backup file for unknown reasons the only button is "OK"

How can I start finding out what is going on and is there any means to save my certificates?

Unable to run firefox. I get the error message. (see attached screenshot) After terminating firefox processes, I attempted to create a new profile. and see an error message. (see attached screenshot)

The address bar is driving me crazy tbh. I want to search for something from it and it works most of the times but doesn't some other times, and I don't know why. I did try to refresh firefox after you click the helper software to uninstall it, but it still doesn't work all the times, and I also tried this (https://support.mozilla.org/en-US/questions/1337970), yet it still doesn't. I might try to uninstall and install it again but is there anything else I can do if it still doesn't work?

Lost my session. Not the first time, so I went to retrieve it with sessionstore.jsonlz4 Put it in the directory above the backups as usual. Not working. No matter where I put it, Firefox is not restoring my session. Tried everything I can think of, no joy. Would really like to recover my session. Has the location changed? Different file name? Firefox has done a lot of updates lately. I am on a pc operating WIndows 10.

[Lost my session because I had a private window open when I closed my regular window. FYI]
