Why does Firefox take up so much RAM?

I have been using Firefox for the past 2 years, but only recently have I noticed that Firefox is using 1 GB of RAM! It never increases or decreases and its getting very annoying now since I have barely any RAM to run zoom with (which for some reason takes up the rest of my RAM). I can't even run anything else, and thats annoying me a lot since my fan has to keep running. I can't upgrade my RAM because I use a laptop, and my laptop is under warranty and I can't afford to lose the warranty by upgrading the RAM. Is there any other way to decrease memory usage beside using about:memory and pressing the "minimize memory usage" button? Nothing happens when I press the button.

Hello,

I just upgraded to Firefox 87 and noticed that I wasn't able to go back to the previous webpage by clicking on the backspace button like what I have done in the past if I'm not using a mouse on my laptop and had to click on the back button in the toolbar with the trackpad. I'm not too sure of why that happened with the upgrade and was a little surprised about that. Hope I can be able to get around this in some way if one of you know anything about this. Thanks.

dear ladies and gentlemen,

Firefox has been delivered with the new print dialog since version 82.

I have to print around a hundred PDF files at work (usually only the first page of the document). The new print dialog means that there is a lot more work for me here.

Is it possible to set the "old" system print dialog by default or to instruct firefox to always print only the first page of the document by default?

Video's won't play

I am running "Firefox Browser 93.0", and I have Windows 10 Pro Version 21H1, OS Build 19043.1288. I am unable to watch certain video's, as an example, the video in this link: [https://www.wandtv.com/news/illinois-.../article_24b92a86-32c4-11ec-a487-3bb3f17fa133.html] won't play. It use to work, but something has changed, not by me. It will play that same video using the "Edge Browser" so there is nothing wrong with the website. However, I can play this "YouTube Video": [https://www.youtube.com/watch?v=qAJSYk5wMiA] I also tried another link in their website, this is the weather link: [https://www.wandtv.com/weather] it starts to play, but then stops and nothing ever plays. Here is another link I tried on their website: [https://www.wandtv.com/sports/fans-ma.../article_f94f4ade-32e0-11ec-9351-ef71f52b96cd.html] It won't play either. But they all play in the "Edge Browser!" Any ideas on what changed and how do I change it back, so they will play? I prefer Firefox Browser to any other browser! Do you know what the issue could be? I appreciate your time! NiceSeeingYou

Hi Firefox start to take a lot of CPU depending on how many tabs are opened (that is normal of course especially if with flash contents). What is not normal is that CPU will not be released when tabs are being closed, even with one (blank) tab left opened CPU usage is 40%-85% (depending if other process need CPU). Essentially: once Firefox process obtained 80% of CPU you can close tabs but you are fucked the same, now opening new tabs is a pain! Of course restart fix the issue. Is not a matter of addons or updates, Firefox and system (Windows 10) are updated to last version; I feel is something related with flash contents. Is it possible only me experience this?! Regards

Downloads almost always fail: '.part could not be saved, because the source file could not be read.'

Error message: E:\Users\Sarah\AppData\Local\Temp\xxxxx.xxx.part could not be saved, because the source file could not be read. Try again later, or contact the server administrator.

I do want to mention upfront that this issue is also affecting Chrome and IE. It's not solely a Firefox issue, but I'm hoping someone here can help me anyways.

  • This happens for any filetype, from any source.
  • It started happening about a month ago.
  • Prior to that, I installed a new motherboard, RAM and processor. I'm fairly certain there was a period between these events in which it worked fine, but I am mentioning it just in case it's relevant.
  • If it's a small file and I try repeatedly, it sometimes will eventually download.
  • Even if a large file successfully starts downloading, it will eventually fail. It usually fails immediately though.
  • I sometimes have success downloading the same file in Chrome, but it also often fails. IE as well.

I have tried the following:

  • Used Refresh Firefox
  • Cleared download history
  • Changed download location
  • Reset browser.download values
  • Disabled firewalls and antivirus/spyware
  • Reinstalled Firefox using Run as Admin (first uninstalled previous version and deleted all program files that I could find, including profiles)
  • Cleared cookies and cache
  • Ran in safe mode
  • Verified Temp folder filepath was valid
  • Verified the PART file was created in that path -- it exists until I hit OK on the error message, then it disappears
  • Ran Firefox as admin

I think these are outdated methods I only found on non-official sources, but will mention them just in case:

  • I found some sources that said to delete Compreg.dat; I could not find this file in the place listed, nor could I find it with a search of the entire drive
  • Verified places.sqlite was not set to read-only
  • Removed read-only from entire profile folder and subfolders

In Options > Security: 'Block dangerous & deceptive content': true, 'Block dangerous downloads': false

Internet speed test: 58.96 Mbps download; 148.04 Mbps upload. No connection loss.

This problem is absolutely maddening. I'll be so grateful if anyone can help me out!! :( Thank you in advance, I know this was a long read!

"If you are connected but behind a firewall, check that Firefox has permission to access the Web."

I get the above instruction when I can't access a website--but I don't know exactly what I'm supposed to to. My firewall is the one installed with win10.

Ever since the last update, every time I download something on Firefox this download tab pops up every time when the new download is complete. Ive tried disabling every extension, Ive tried the about:config solution I found on this page, setting it to "false" and I havent been able to find anything in tools or settings.. but nothing disables it and its getting annoying. Ive had Firefox for years and this has never happened before.

Some of well known sites such as "drive.google.com" & "mail.yahoo.com" is resulting in "Did Not Connect: Potential Security Issue page" in Firefox. They are opening just fine in other browsers.

This issue has cropped up since past week in Firefox. Not sure what is the root cause behind the problem. I have tried re-installing Firefox, but still no change.

I have checked the certificates of those sites, and they are seems to be in order. I mean other browsers are able to open without issue, then why Firefox is not opening them for me?

Please let me know if this issue can be fixed in Firefox.

How can I change the DNS Server in FireFox

Enabling DNS over HTTPS dose not give me FULL control over this. I should be able to put a DNS IP address in there like in Internet Explore.

Hi! I found a strange thing today. I wanted to open an ftp link and firefox asked me in which app I wanted to open it. Of course I wanted to open it in Firefox, but the only app on list was Internet Explorer. So, I added Firefox to the list, but I couldn't open the link with it, because when I marked Firefox and tried to click "open", nothing happend and the box still appeared. So, I ended up using IE. I'm using Firefox Nightly (81.0a1 atm of encountering this).

I'm using Firefox 85.0.2 . . . I was doing this (below), to customize my header and footer, but in this version of FF, I no longer see this in Options - only in: about:config . . . keyword "footer" . . . there, I would have to change it for 5 different ways of printing (to printers or to PDF)

I need to get rid of printing the URL in the footer - many times, it's too long, and I don't need it.

Where did the Page Setup option go?

I see in the current Print Options, you have to go to - More Settings / Margin / Custom - to see those. Why would they put this so many levels down?

It used to be: File / Page Setup / Margins & Header/Footer . . . "Customize" Headers & Footers:

Option 1 (left) . . . there are two leading spaces:

 > > &T
 > > &U . . . &D . . . &PT

Option 2 (left) . . . get rid of the ">"s, and just have the two leading spaces:

 &T
 &U . . . &D . . . &PT

I'm trying to take off this "Extension (Tabliss)" tag on my url. I have followed the instructions down below from another Firefox support forum: https://discourse.mozilla.org/t/make-addressbar-text-extension-name-of-the-extension-shorter-or-hide/28026/3

The instructions I followed are listed below:

"Users can apply custom style rules to modify Firefox’s toolbar area by creating a userChrome.css file. This takes about 10 minutes so when you have time to take it slowly and carefully:

(1) Set up your chrome folder and userChrome.css file following the five six steps in this article:

https://www.userchrome.org/how-create-userchrome-css.html 45

I have a boring video there if you like demonstrations.

(2) This is the code to paste into the file. You can edit the file using Notepad or a better editor. Make sure to keep it in a plain text format with a .css file extension (not .css.txt).

See improved rule down in: Make addressbar text "Extension (Name Of The Extension)" shorter or hide

/*

  Hide Extension Name in the identity area unless
  hovered for half a second (updated for Fx80)
  • /
  1. identity-box.extensionPage #identity-icon-labels,
  2. identity-box.extensionPage #identity-icon-label {
 visibility: collapse !important;
 transition: visibility 250ms ease-in-out;

}

  1. identity-box.extensionPage:hover #identity-icon-labels,
  2. identity-box.extensionPage:hover #identity-icon-label {
 visibility: visible !important;
 transition: visibility 250ms ease-in-out 500ms;

}

(3) Firefox should read the file at its next startup and apply it to every extension page you load."

Edit: So, yeah, I need help getting this tag off. I'm new to Firefox so it could be something obvious I'm missing. I have also tried CTRL+SHIFT+R to reload the page for changes and also closed and reopened my Firefox entirely.

Thanks in advance.
