As a test I inputted a word I found in the document but find in page stated phrase not found. What am I doing wrong? I remember that I have used that feature in the past and it worked.

For a few months I have been having sporadic issues with my cpu running at 100%. I believe Firefox is the culprit. When I open task manager Firefox is running 30 processes with power usage very high. Usually one of the top processes in the drop down is very high. To fix this I have been ending the task of the highest usage process running. In all cases that has brought the cpu down to like 10% and has fixed the issue temporarily. If I'm not at my computer for some time, it will not resolve on it's own. I'm not sure what info you need but will provide. Could this be a bug with the current version of ESR?

I have tried the fixes including: Disable/Enable Hardware Acceleration, Enable Strict Tracking Protection, Delete content-prefs.sqlite file, Check Firefox hardware acceleration, Disable resource consuming extensions and themes, etc.

I am using Firefox ESR 128.6.0 and have been for years (ESR)

Hi Community,

I am writing as recently I noticed that extreme amount of data was written on my system SSD. Here we are talking about 100-200GB of data written daily. In resource monitor I found that Firefox is writing this amount of data in its Profiles folder, but only when Facebook's main page is open. I also noticed that when only the Messenger part is open the problem goes away. Currently I symlinked the Profiles folder onto one of my HDDs so the data is being written there, however I would like to know if anyone experienced the same issue and what could be the solution for this. I completely reinstalled Firefox, my installed extensions are Adblock Plus, Enhancer for youtube and Facebook Container.

By using Process Explorer or Process Hacker or maybe task manager, I hope you can also verify that Firefox consumes a few GDI handles per open tab. Windows has a global limit and a per process limit of 10000. GDI objects are used for windows, for the file save dialog and also for user interface elements like buttons or lists. However many applications like Firefox draw everything themself like XUL etc. But still, Firefox consumes 3 handles for me (verified on another computer) per open tab.

If you have a lot of tabs open (for reasons not to be discussed in this topic) this can be problematic. If it reaches 10000 windows will not create more. Sometimes firefox hangs, but often Fullscreen (e.g. youtube videos) will not work and the gui will disappear. Also the context menu will not open and the save dialog cannot work and is hidden.

Am I the first to report this? I did not find anything. Can this be fixed? Can I post this to bugzilla?

Can anyone confirm this? The latest version does not fix it.

For about a year I have, several times, tried to use a link or a pop up that doesn't work in Firefox but can be accomplished in Safari. Today, I used a credit card to pay for something on the UFT.org website. It worked. I needed to make another purchase on the same website and page but I got a message that there was an error with my credit card info. I tried again. I tried another credit card. I signed out and back in and repeated everything and still got the same message. I copied the url, went to Safari, pasted the url, entered my info and was successful in making the payment. I am using Firefox 133.0.3. What might be happening to cause these problems?

So i am using ReseourceOverride AddOn to debug a js library on standard install of firefox. This works by using the site as normal but resource override has instruction to replace request for the library on server with one requesting it from localhost. This used to work without problems. However today i noticed that breakpoints aren't getting hit. I have downgraded to version 132.0.2 and breakpoints work once again. I think this has something to do with debug sources, since the load process adds 2 sources, webpack containing uncompiled code and where i set break points, and webpack-internal which i think is built js library before getting minified. Links to exceptions in console also dont work instead of linking to webpack seemlesly, the adress says webpack-internal and link open a new window and complains that the adress is nonsense (see attached images)

This is something I've noticed in the last couple of mouths...

Initially everything on Firefox runs fine for the first 1-3 hours, but after that the multiple YouTube website video tabs I generally have open, especially the very last YouTube website video tab that's open, or any new YouTube website video tab I open, starts to lag like crazy.

Using my mouse to click the play/pause on the video player, or pressing the play/pause function key or spacebar on my keyboard, takes a good 3 or 4 seconds before the input action is registered, and it's not just that but the entire UI of the web page itself is slowed down.

Doing simple things like clicking on-screen buttons to navigate, and scrolling down to load comments, or scrolling down to load other video thumbnails etc etc, takes a good few seconds to actually work.

In general the YouTube tab(s) become very slow and unresponsive, and it's not just the video player on the tabs - it's the YouTube website in general that is affected.

I don't see a substantial difference in CPU or RAM in Task Manager when these 'slow downs' occur, but the fan speeds inside my mini PC do spin louder and louder.

For whatever reason this problem ONLY happens with YouTube. Other websites via other tabs tend to run and function just fine 24/7.

I'm running the latest 133.0.3 version of Firefox, and my system specs are as follows:

Processor: Intel(R) Core(TM) i7-10700T CPU @ 2.00GHz Storage: 595.2 GB Installed RAM: 16 GB (15.7 GB usable)

Other people have also reported similar things over on Reddit with regards to Firefox and YouTube.

Firefox seems to run slow. I rebooted my new Windows 11 computer (Dell Inspiron 16, Intel Core 11), opened up Task Manager, then opened Firefox. I have one browser page open with one Firefox tab, yet the Task Manager is appearing to tell me there are 9 Firefox "pages" (?) open; see attached image. What is this? Why is this? Is it slowing performance? I have run Firefox for several years and would like to keep doing so; just not sure I can deal with the slow performance. Thank you for your consideration & assistance.

I set to automatically hide the task bar. in my Windows 10 Enterprise 64 bit Version: 19045.5131, 22H2, on a HP 840 G3 notebook.

When Firefox is running in full screen, tmoving the cursor downwards does not cause the taskbar to appear. This happens oly by pushing the Windows button.

No problem at all with other browsers, like edge, chrome, and brave.

Suggestions really appreciated.

Thanks Carlo Maria

Recently, the Firefox browser stopped working. Specifically for me, Costco's website, and Aetna. I believe the issue could be that those websites require that the location is confirmed, but no pop is generated, thus causing the website to not work with Firefox. Please help me, as your browser is the best.

For about 2 weeks now, the audio volume on youtube videos fluctuates up and down. The volume starts off low when a person starts to talk. For example, when the person in the video starts to talk, their voice volume is very low then within a second or two, the volume rises to normal as they talk. When they finish a sentence and start a new one (when there is a short pause in the audio) their voice is again at a very low volume, rising to normal in a second or two. This repeats as they speak throughout the entire video. This is not specific to any youtube video or youtube channel, it happens on all youtube videos. I have tried updating all audio drivers in Windows 11 - no improvement. I have tried rebooting the computer - no improvement Firefox is up to date, version 133.0 I have tried watching the same videos using Chrome and I do not have this problem. Any help correcting this would be greatly appreciated.

Thanks, Brad

There is a similar (but not identical) topic on Mozilla Connect , and I posted there. But I did not get a response. So I am re-posting on this new topic on Mozilla Support. I have a similar problem to what was discussed on Connect. I am using Firefox 133.0.3 on Windows 10 Professional. After Firefox has been running for a while, I get a message from Windows 10 that the free space on my C:drive is low. I did a directory listing on my C-drive before and after Exiting Firefox; I saw no large files disappearing. Then I decided to do "dir c:\ /ah" to see hidden files. What I saw was that pagefile.sys decreased in size from 29,925,748,736 to 16,270,770,176. This was a decrease of 13.7 Gb. Is this normal? I have lots of windows and tabs open in Firefox. Thanks.
