This happens only on Firefox and Firefox Developer Edition on one of my PCs and not the other. Firefox is version 113.0.2 (64-bit) and DE is 114.0b9 (64-bit)

Anyone experienced this before?

Hello, I hope someone can help me.

Ever since I updated firefox, my cpu is almost at 100%. With only 2 or 3 tabs open. I updated from version 106.0.2 to 112.0.2. Before this update, I could have several tabs open, up to 10 and the computer would run fine. Now with 3 tabs open, it gets really slow. And I can hear my desktop suffering (the fans go to full speed). When checking the task manager, firefox is taking all the memory and the cpu usage is almost at 100%. I have to keep restarting firefox.

The conditions are the same. The only thing that changes was updating firefox. I already searched for ways to reduce the firefox cpu usage, but nothing changed.

Is there a way to fix this? Or how can I go back to an older version of firefox? Because I'm afraid my computer will die from simply opening 3 tabs.

Thank you in advance.

Every time I go to Fox News, the video at the top of the page drops to the lower right-hand corner. It's an annoyance I've been searching for a way to eliminate. I have pop-ups blocked in preferences and I have a couple of different pop-up blockers, but nothing seems to work. I'm currently using Firefox 114b.09 on a Mac Desktop.

Hello Volunteers,

Ubuntu crashes while moving around a Firefox tab with a mouse, IF the mouse cursor goes thru the top bar of the laptop screen. I am using Firefox V 113.0.2, Build ID: 20230522193126 on Ubuntu 23.04. This could be an Ubuntu problem or a Firefox problem.

Thanks Dilip Deodhar

I have noticed in the last few days that Firefox is keeping my Mac from sleeping. This seems to have started around the time of updating Firefox to version 113.0.2 which happened 4 days ago. Any thoughts on how to debug this?

I have an extension (completely blank) that can't be deinstalled. I am trying to use the "refresh firefox feature" to get rid of it, but the button simply isn't where it should be. The text is german, but none if these Buttons are the one I seek.

My laptop died but I have been able to rescue the SSD and turn it into a USB connected external drive. I can see all data from my old PC.

I have tried to copy all of my User, Local Apps Data Mozilla Profile data folders to my new Laptop but the data does not appear when I fire up Firefox on the new laptop.

The old laptop folder was c:\Users|Phil, the new laptop is C:\Users\Phill {setup of new PC added a second L to my name}

Is this an issue ?

Radio buttons on some websites neither display nor update when the area in which is should have displaed is clicked. FireFox 113.0.2 (64-bit) on Mac OS X 10.13.6 (High Sierra). This problem has been present for some time. On other websites the radio buttons do display and do upate when clicked by toggling the dark center. The minority of websites which don't work seems random, but does include some banking websites and the IRS.gov website. Often using SAFARI will work when FireFox doesn't.

The CheckBox at the end of this page "Email me when someone answers the thread" appears but does not respond to a click.

Everything under Logins and Passwords, and Forms and Autofill is unchecked. A "Primary Password" has never been set in firefox.

Can't get it to stop asking, which is made worse by the fact that nothing is selected to prompt it nor is anything stored for it to use.

Scroll down until you find "PERMISSIONS" and find for "Camera". Click on "Settings" that is parallel to "Camera". Now, select/type all websites, that you want to give permission/access to your camera.

Never used a webcam before, but i did that... the site is there, it says allow... i'm on the website now, says webcam not found... am i forgetting something? do i even have one? i'm at the library...

Hello everyone.

I've been using Firefox for quite a few years now and I'm used to keep my pinned tabs open after closing and then opening a Firefox windows.

Yesterday I noticed that after closing the navigator with the "X" in the tool bar menu, as I usually do, the pinned tabs are not "recovered" when opening again.

This happened randomly without configuration changes involved and drivers/firefox are updated to the last version available.

Moreover, I've tested the same in my notebook and it works just fine, as it keeps the tabs open when a new window is open.

Is there any troubleshooting for this or do you have any idea what could have caused this to happen?

Let me know if you need any additional info. Thanks in advance!

i can share everything that would solves the problem. thank you in advance.

I have a website that open pop-ups automatically using javascript. That is the expected behaviour of it. So I went into Firefox options and made an exception for that site. If I go to the site and wait so it can do its thing, it opens about a few of them, and then Firefox decides that the rule I have set up is garbage, and firefox decides to ignore it and block the pop-ups from the site.

Why?

Why on Earth does Firefox decides that he must do something against the rule that the user has set up. Why does it have this completely disrespect to the user settings?

I am honestly really mad at whoever decided that ignoring an exception from the user was the default behaviour.

Now, if someone knows enough what is going on they will tell me, go to about:config, go to this obscure command and change its value, value which I can't know without coming here and ask. If I create an exception, then I am in my right to expect that the browser should do exactly as the exception has been configured.

By the way I have tried with the troubleshooting mode and still happens.

These bugs have probably already been reported but just in case they haven't there's an issue where dates can't be viewed on Facebook posts without hovering the mouse cursor over the title of the post. The other bug is the cursor often, but not always disappears when commenting on posts.

Hello,

I am a developer on an emergency intervention hotline for sexual assault.

Firefox is now throwing up psuedo-modal advertisements for it's VPN above pages. See attached screenshot for example.

It is absolutely IMPERATIVE that our visitors do not receive these new modal advertisements that Firefox is throwing at them. What can I do to prevent Firefox's new browser-hijacking advertisements from showing up on our hotline pages?

I experienced this on Twitter, and it 100% was not part of the dom. It also greyed out the tab bar, and prevented me from opening the menu with alt. I know how to make it not show up anymore on my machine, but how can I prevent it from appearing on visitors to my website, who are in some of the most vulnerable times of their life.

I noticed that on Facebook there is not shown data and time on every post. Some posts show this info, the other don't. I cleared cookies, deleted Facebook from history but it didn't help. On Chrome everything is showing normally. I put Firefox in solving problems mode, with add-ons off, it didn't help too. Any solutions?

I stupidly upgraded to the worst system in the world, Windows 11, and the silly animations caused serious strain on my device. I disabled the animation effects in settings, but now when I use Firefox as usual, the loading page icon animation has become a static hourglass icon, which is unfriendly. How can I enable the loading page icon animation while keeping the system animation effects turned off?

The title pretty much sums it up. I even tried drastic measures such as logging out then completely uninstalling Firefox and removing any leftover data on both platforms. After reinstalling and connecting to the Firefox account they will sync with previous data but any new data I add on Windows won't show up on Android and vice versa. I also obviously tried forcing a sync manually... I really wish I didn't have to switch to another password manager any help would be greatly appreciated! :)

I'm using the latest version of firefox, at the moment i had a trouble. Text of timeline zone of my facebook hidden, first timeline unhide but other timeline hidden. I'm restart my firefox, remove and resync ... but this error continue. I'm try other browser as chrome, brave no error. How to fix it? I'm the fan of Firefox but user experience too bad with this error I'm upload some images screenshot with error and no error with chrome browser. ++
