Firefox Community Forum

I'm using the latest Firefox on Win10, with a fairly powerful laptop (64 gb RAM, intel i7 2.3 GHz chip), and for about a month now, whenever I use it, it uses so much CPU all the time that my laptop is overheating (slight hyperbole, but it's definitely churning the fans a lot, and the area around the keyboard gets hot to the touch). Sometimes it uses up to 45% CPU, and over 20% memory!!! (as reported in the task manager) Usually around 20-25% though. While Chrome, at the same time, is using 0.1%. It's not just when starting up, either, it's continuous during use, until I quit Firefox.

What the h*** is going on?!? I've tried the troubleshooting steps, but it remains crazy regardless of turning off extensions, and I'm just using the default theme. I notice it's mainly when loading images, like on social media.

This is insane. What is happening. Can someone help me?

Every time Firefox updates it keeps re-enabling settings on its own.

Specifically 2 settings on the general tab keep enabling themselves in the "browsing" section, "Recommend extensions as you browse" and "Recommend features as you browse"

I have disabled these settings dozens of times now, and every time Firefox updates it keeps re-enabling these 2 settings on its own.

Just now I updated to v128.0 and these 2 settings turned themselves on again.

Why is Firefox not respecting my settings? Why is Firefox allowed to modify my settings without my permission?

I have deleted and reinstalled Firefox already. I don't use profiles and am not signed into the browser, so no settings are getting carried over that way.

On my laptop (121.0 on doze 10) I have no problems but on my desktop Firefox (121.0 on doze 10) started to struggle with Google a few months ago. Sometimes the Google site doesn't load, sometimes it loads but doesn't connect (no auto-complete, no search) and if it does work the result links often don't load when clicked. It's like Google falls asleep and then, when it wakes up, all is fine, until it nods off again. I have followed advice provided, cleared cache, cleared cookies, removed plugins and extensions, reinitiated and reinstalled. Running in safe mode seems to help, as in pages seem to load faster, but sadly does not eliminate the problems. Other browsers on this machine are not affected. No time sync issues.

Any suggestions?

TIA

Unfortunately using a date type toJSON() result is not accurate. It first apply client timezone and then convert it to json string. In my scenario I am simply read from an API which return a none standard datetime string without its timezone (like "2020-11-21 00:00:00"), Then I try to convert it to a date using new Date("2020-11-21 00:00:00"). Then I use it in another web service but it apply my client timezone when I use JSON.stringify() method (or toJSON()). Does this behaviour is intentionally?

I read the other same question but I am not okay with it. https://support.mozilla.org/en-US/questions/1414380

I use Mozilla Firefox for work. Part of my work requires I use the GlobalProtect VPN client. When I log on to the VPN, everything appears to be fine. The problem arises when I log out of the VPN client, such as needing to switch to a different VPN.

When I log out of the VPN client, Mozilla slows down massively. I get the following errors when trying to access websites.

PR_END_OF_FILE Timeout

I thought it was a DNS issue, but the change I made previously did not prove to be a reliable fix, and I do not actually know the root cause of what is happening. Firefox returns to normal ONLY after a full computer restart. At this point I am considering switching browsers as, despite Firefox's functionality, it is starting to interfere with my work.

I have used other VPNs, such as Fortigate VPN, and not encountered anything like this.

Any advice or guidance would be appreciated.

Hi all, my website isn't opening when using firefox. But when I try to open it in chrome it opens smoothly. I'm a user of firefox and this issue is creating a mess for me. Any help welcome. Site Link: [=]

Before the recent 1-2 updates, pdfs,pictures and .torrent meta files used to get saved in temp folder which I LOVED very much. Recently these are getting save in my download folder instead of saving in the temp folder.

I changed this setting to allows ask. Still the files are getting saved in the download folder after opening.

Please assist me to resolve this issue. Thanks.

I am sick and tired of Firefox denying me access to common store websites. How do I turn off your firewall? I want to shop on Lowes.com and I cannot get access. Firefox is proving recently to be more of a problem than an asset.

Hi

OK so I was having some issues with firefox where I had to reinstall it and this did in fact resolve the issues I was having.

Problem I have is this though when I reinstalled it I first backed up my chrome folder which had all my custom CSS to move the tabs to the bottom of the header area and when I then reinstalled FF I then copied the folder back into my profile folder using the More Info under the help menu to make sure I was in fact in the right profile folder.

Problem is the code isn't moving the tabs and I seem to remember some issues with this the last time we had to fix FF that something had changed with the Chrome folders and such.

So what do I need to do to get my tabs back on the bottom again as I hate them up top!

Version: 128.0.3

Thanks!

Can't log into NYTImes.com with Firefox. I use Bitwarden for passwords. I also have UBlock Origin, but that should not affect logins. I clear cache and cookies upon browser close. I ended up resetting Firefox entirely, which was a royal pain, it worked for a few days and now is not working again. I have no problems logging in with Chrome but Firefox is my preferred browser.

Also having problems with the captchas on Etsy. I get endless captchas, like for five minutes. I set up 2FA in hopes it would stop with the captchas but that only worked once and now it's endless captchas again. Yet no problems on Chrome.

The NYTimes problem is recent and started early to mid-August 2024. The Etsy problem started maybe late June? Same password manager, same extensions. I hate to go to Chrome every time I need to log in. So far these are the only two websites that consistently give me problems. Does anybody have a fix?

Can't pinpoint the date, but a while back Youtube won't play videos anymore. It just shows a black screen in the player. Not even the player UI (pause button, volume, settings menu) shows. Just a black portion of the screen. Now when I went in to get a screenshot, it doesn't even show the black box.

I just installed 3 Add-ons Free Memory, Free Memory Button and Ramback but, apart from them showing on the Add-ons Manager, I can't find them let alone open them.................Does anyone know where they could be or what happened? Thanks in Advance

Recently, I've run into logging in on at least two websites where I have two-factor authentication set up. I'll click the sign in button, and rather than advancing to ask for my authentication code, I get stuck in an endless loading loop and am unable to do anything.

Is there anything I can do to fix this? I have already tried clearing cache and cookies and restarting in safe mode.

This issue only happens to me on desktop. The mobile version of firefox still lets me log in, but I prefer to use desktop.

I used to have a "reload" icon on the bar with "home" and other things like "bookmarks." I found it in the "overflow" icon place. I tried to grab it and place it where it used to be on the toolbar. It disappeared and I have no idea where it is now. It's not where I found it in the "unused buttons."
