Firefox Community Forum

Hi, I’ve noticed that Firefox often uses a lot of memory when I have multiple tabs open, even more than Chrome or Edge on the same number of tabs. Sometimes it slows down my system or makes switching between tabs laggy.

Is this normal behavior, or is there a way to reduce Firefox’s RAM usage without losing performance? Are there specific settings, add-ons, or troubleshooting steps I should try?

Thanks in advance!

I have been an avid (make that RABID) Firefox user and advocate for more than a decade. I recently had to wipe my hard drive and am still going through the painful process of putting things back the way I like them.

Firefox is (was?) my preferred and default browser. I use other browsers only when forced to for work or when Firefox doesn't function with certain apps.

Now, the new version of Firefox does not allow me to set my own home page. I have a choice of Firefox or blank for new tabs. Yes, I can click on the Home icon to get to my preferred home page... but that's another step. Why?

It's only one day in, but honestly, I'm seriously thinking about moving to another browser that doesn't require me to MANUALLY click a home icon to get where I want. WTF?

Whatever you say, you've made it super difficult for this loyal user.

Hello,

Firefox is able to read and reproduce any video or audio streamed on the internet. So, I can record the output from firefox when it plays music from Youtube for example.

But if I want to get the original stream, before it is decoded by Firefox, I couldn't find a solution. Yet it would be enough to make a fork in the Firefox module (which identifies the codec, process the audio stream and sends the result to the audio device) and make available the raw audio data in a place where the user could know the codec and the bitrate and choose the best solution to store this stream. It is not usefull to use a vorbis encoder at 320 kb/s if the input is an mp3 encoded at 128 kb/s !

Is there any solution to do this ? Thanks.

Does anyone know how to remove the the keyboard shortcuts from Context Menus? For example: Ctrl+Shift+O beside Manage Bookmarks, or Ctrl+Shift+H by Show All History? I like having them gone so the menus can be narrower. This code worked until the latest update to FF 143: .menu-accel-container{display:none!important} thanks!

Hello,

I have version 143.0.3 (aarch64), running on a 2020 M1 mac. I did an update recently but I still have all of my bookmarks, that's not the problem. The problem is, although the space for the bookmarks toolbar appears when I click "always show" (and disapears when I select "never show"), I see nothing. Nothing shows up in this space and so I have to go menu diving to get to my bookmarks. Do you have an idea how to fix this?

For the past few days hot links in Thunderbird do not open in Firefox. Selecting a link in an email opens or brings to the fore a copy of Firefox with the link address and the wait icon but nothing else happens. I have to close Firefox, copy the link location, Past and Go in Firefox, and then the linked page appears. This behavior happens even in Troubleshoot Mode, so it is not any plugin or customization. I am also running Mozilla VPN. With VPN disabled, hot links in Thunderbird open in Firefox as expected. Now you know where to look.

Also, when I tried to add Troubleshooting Information below, nothing appeared. When I selected to option to be shown what to do, this page was replaced with other which deleted all this text, and now I am entering it all in again, which is severely frustrating. On a page where the user has entered possibly a volume of information, there should not be any sloppy risk of deleting that information due to page mishandling. Open help or assistance information in a separate tab, please. Think ahead about this stuff. You are supposed to be web design experts. Instead your web site spits in my face just when I am asking for help. Think. Plus, I had to get the Troubleshoot information manually so that is not being as automatic as it appears to be , either. Getting help should ideally be a button click, not jumping through hoops.

I am an academic researcher formerly affiliated with an institution that uses Okta as its two-factor authentication service for access to institutional subscriptions (think Elsevier, Cambridge Core, Brill, JStor, etc.). Since I am no longer affiliated with that institution, I am no longer authorized to access that institution's subscriptions. I am not trying to access that institution's subscriptions, however, if I try to log in to these repositories as an individual, I am automatically redirected to my former institution's Okta authentication page.

The browser: Mozilla Firefox 143.0.3. I am able to access other sites on other browsers, as well as in private Firefox windows, which suggests it is a problem with my Firefox account. These are temporary workarounds I can live with only in the very short term. I am under no circumstances willing to switch browsers. I use Firefox for a reason. FWIW, I am also contacting Okta support to see what they recommend.

The computer: Macbook Air 2020 M1. It is a personal computer. I do not have access to another device.

I have cleared my browser history, saved form data, saved site settings, cookies, and cache (x5). I have deleted all saved passwords containing the email address associated with my former institution. I have restarted the browser (x5). I have restarted my computer (x2). I have reached out to IT at the institution (they are flummoxed).

I'm nearing my wit's end with this. I'm working on multiple projects with multiple deadlines. The temporary workaround and constant barrier to access are driving me up the wall. I will be infinitely grateful for a permanent solution to this hellish problem.

When I type in a Google search in Firefox, a red dotted line (not the wavy red line from Firefox's spell check; spell check is disabled) appears. What exactly is this red dotted line? Can I show or hide it in settings? Can I change the setting in about:config? Please help. It's very annoying.

When I search Google Images in Firefox, this pops up. I tried using an extension to hide it, but I can't see the rest of the image, which is inconvenient. Microsoft Edge and Google Chrome load it, so it's not an issue. Is this a Firefox feature? It's a hassle to disable the extension just to read the rest. Could you please give me some advice?

In the main page (new tab), upper right corner the weather is displayed. However, in my case it shows Paris, France. Been there! - but not in 40years.

the three dots beside the location open a search bar that does nothing. i enter my location... does nothing entered my zipcode... does nothing.

restarted my browser ..... no avail restarted my pc ... no avail

cleared cookies ... then restarted browser ... no avail

Windows 10 firefox ver: Version 143.0.1 (64-bit)

side note: this issue is also on my laptop w11

I have picked up some bug(s) on my Firefox that I cannot figure out how to get rid of. With a Firefox ID I have warnings of 3 Trojan Virus detected, Virus detected, hard drive infected, secure data notice and system alert. I also got a warning that my McAfee protection had expired which is very strange. Since switching over in 2010 from Windows to Linux I have never had protection of any kind and unlike Windows have never had a single problem. In addition when I was using Windows the protection that I had was never McAfee. I suspect that these warnings are not from Firefox given the misprints, spelling errors and the poor English. It is likely phishing from some third world country. How do I get rid of this obvious garbage permanently? Many thanks! Kris

I am having problems with Firefox not scrolling (and no scroll bar) on some web pages. The following is an examble:

I am using Windows 10 and Firefox 143.0.3 (64-bit)

Any help would be appreciated.

Bonjour,

Sur un MacBook Pro sous OS X 10.9.5 j'ai chargé firefox 78.0.2 64Bit et il est impossible de changer le language pour le mettre en francais. Pouvez-vous m'aider, merci

Hi! I'm on a relatively new to me (refurb) desktop computer running Win 10 Pro (64 bit)* and Firefox 143.0.3.

In the past week both Firefox and Win 10 have updated. I don't know what happened, but now when I boot up or reboot, my computer opens to MS Edge. Yuck!

Every single time I have to reinstall Firefox! Once I do that, all is well again. I have all my bookmarks back, etc.

It also keeps changing my "default to Firefox" browser setting, turning it OFF, while I'm using Firefox. I repeatedly have to keep going in and clicking to make FF to the default browser again.

Why is it doing this? How do I stop it?

Anyway, I know I can't delete Edge or uninstall it. How do I shove it back into the black hole it has lived in until now?

Thanks very much in advance for any help offered. :)

I prefer Firefox over all other browsers I've tried

About a year ago, I think, after an update I couldnt copy a chat into LibreWriter that included the name of the chatter.

Disappointed, I found Brave browser that does copy all within the chat window.

The thing is is Brave is unreliable, and often the chat locks up after an couple hours unless it is regularly checked -I stick with Firefox for my involvement, using Brave to record only because it lags while typing, sometimes so badly a whole sentence can be typed before it appears on screen.

Can you restore the code that allowed the name of the chatter in Rumble chats to be copied like Firefox used to?

It would be much appreciated. Thank you, Biff

I use both Firefox and Google Chrome. My mouse works fine with Chrome but with Firefox there are frequent long delays (60-120 sec.) when moving from one web site to another. The mouse just freezes up and I have to struggle to close Firefox. No problem with the mouse with Chrome, but I prefer Firefox and its features. Any suggestions?

I am using version 88.0 and browser, both outdated and not supported. How do I update to current version and update browser? I am 80 yrs old and not computer literate, please keep it simple. Also, I am alone, not help available. Thank you
