Until now I have always used the mouse scroll key to open links in a new tab in firefox. Now it does not work anymore. I have to right click the link and choose to open the link in a new tab. Have been looking for a setting for it, but can't find it. Is this something new? I want Firefox to work as it has always done sincce I started using it many years ago. Please help!

When using firefox, and only when using firefox, I experience quite a lot of lag when using "google docs" (https://docs.google.com) and only when using "google docs", eg. this does not apply to, say, MS Word or google presentations.

Like I said this only applies to firefox, meaning google chrome and microsoft edge both work fine.

Here are some of the troubleshooting steps I've tried, without success:

  Launching in troubleshooting mode

  Disabling 0-RTT

  Disabling hardware acceleration

These issues do not appear on my machine at home, which also uses firefox, that however is a different version of Windows, an AMD cpu and a dedicated GPU instead of integrated, so idk if that narrows it down even one bit...

The computer on which the issues appear on is a HP Spectre x360 14, which if you don't want to search it up means I have 32gb of RAM @ ~7500MT/s, and an Intel Core Ultra 7 155H as my CPU.

I'd love to keep using firefox without having to fire up chrome every time i need to write/edit a document, which, as a student, is quite often...

Thanks a lot!

Help me return to correct settings in Firefox so I can enjoy playing "June's Journey" and "Pearl's Peril"(which isn't opening). As I explained in my question, there's a wide band across top of "JJ" game which appeared, as well.

 About one week ago, I was trying to re-set use of my debit card, was unable to as I'd probably severely cancelled it 6 months ago. I don't have a clue as to what the connection between these two activities have to do with each other but it's all I have to go on.

Thank you for any help! I've asked Wooga to give me some steps; I tried following them but Pearl Problems continue to plague me.

I have the same problem as in jimkimbroughjr 1/30/25, 9:13 AM message about bookmarks. I have tried the steps in the response, and they do not work for me. My bookmarks disappeared this afternoon, although they were all there this morning. I went to some sites I remembered, and only one had the blue star in the menu bar. Trying to recover the bookmarks through Settings did not work, even when I saved a bookmarks backup file to HTML and tried to import that. Troubleshooting information should be below. I had to use the manual method and I hope I copied and pasted the data correctly. Back to the bookmark problem: Now what?

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)

Thatnks for the help

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.

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.

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.

Every time I boot/wake my computer, it takes at least 5-10 minutes for firefox to connect to the internet. I can open chrome or edge just fine.

I've tried reinstalling firefox, i've checked my win11 firewall settings, I've ensured that i'm not running through a proxy and have checked DNS.

Please help!

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.

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?

firefox has been eating up all of my monthly data in 10 days for the last 3 months. As far as I know I am not doing anything differently than the previous 3 years. In the past 2 days Firefox has used 1gb of my monthly 10gb. Thanks in advance for your recommendations Ken

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

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

I've used FF for years. The last year, it does not function correctly on about 20% of sites. I suggest focusing on making it compatible, rather than requiring sites that are perfectly coded. I may have to drop FF soon.
