Firefox Community Forum

My system memory is reading at 57% right now in task manager, that the vast majority of that is being used by Firefox.

Why?

Normally, this would be called a flaw in the program, not the user, as all I have done in regards to settings is "keep tabs previous open when re-opening Firefox" and "Do not automatically update" because Firefox took it upon itself to not re-open my previous tabs on the last update.

Why is this program eating up all of that memory? I have "Firefox (15)" in Task manager under "Apps" and then 13 more instances of Firefox in "Backround Processes"

Wtf?

I'm visually impaired and had originally used a CSS code to fix this problem, but that was a couple of years ago. I just upgraded to 131.0.3 (64 bit) and evidently, that wiped out all my CSS changes. I tried to use the about:config code to change it, but it no longer works. I managed to increase the icon size a little by changing the density to normal, then back to compact. Even on normal, it was all too small.

I don't want to use another profile, because every time I do, I lose so much that it takes me hours to reinstall it all.

Is there an easier way to do this? I've tried a couple of things suggested online, but they were old settings suggestions, and they no longer work either.

ALSO, I now have to use F11 full screen to be able to perform anything on the toolbars. Before this update, I could just move my cursor up to bring the toolbars down, and use the back arrow or refresh easily. Now, the toolbars immediately go back up and I have to use F11 to do anything. How do I fix this?

TIA for any help you can give me.

Is there any Add-on that will shoot a scrolling screenshot (full page screenshot)?

For reference, there's an excellent extension on Chrome/Brave called "Go full screen" which has simple but perfect functionality, one-click automation, saves as either .pdf or .png format to your downloads folder.

There are 4 toolbars at the top of the Firefox screen. The default order from top to bottom seems to be:

 Menu bar
 Tabs bar
 Navigation bar
 Bookmarks bar   (which Firefox apparently calls "PersonalToolbar")

I would like to move the Bookmarks bar above the Tabs bar so the order is;

 Menu bar
 Bookmarks bar
 Tabs bar
 Navigation bar

I tried to use ChatGPT to accomplish this. After well over 6 iterations, I gave up (ChatGPT was still going strong - hallucinating?). The only code in userChrome.css that accomplished this is shown below. Unfortunately it leaves the order as:

 Bookmarks
 Navigation
 Menu
 Tabs

Can a human expert help me where ChatGPT failed? ___________________

How to change home page and new tab to desired URL or any extension of Firefox desktop in 2025?

I am unable to find any way to change how my new tab should look when I click + sign or new tab is opened up on browser opening or re-opening unlike Chrome.

I hate the change of position of typing from the search bar on the current new tab to the URL bar (unseen or unheard in Chrome) that Firefox implemented without considering users who would detest it.

Using Firefox 131.0.3 (64-bit)

I am not able to login into my gmail account. Whenever I try to sign in, it shows the message as shown in the attached image. I have tried clearing all cookies and cache. Also removed all the extensions to see if it fixes it Please help me. I have Linux Mint 22 Cinnamon Firefox version 131.0.3 (64-bit)

I'm using this shortcut all the time and I recently found out it doesn't work as expected. From the Firefox documentation the ctrl+shift+t should re-open the latest closed tab, but this is not the case for me, it always re-open the latest closed window. Which behave exactly as ctrl+shift+n.

From my short research it's not possible to customize Firefox shortcuts without using an extensions, therefore I also don't know how to verify if the shortcuts have changed just form my browser/configuration.

When I startup FireFox, it takes ~15 seconds to show me an page. After loading, it works normal and loads pages within a second, until I completely close the browser, and then the first page again takes ~15 seconds. I've been having this issue for the past few months.

- I tried disabling all my addons - Launched FireFox in troubleshoot mode - Deleted everything in DataReporting\Archived folder - Cleaned out History/Cookies and site data/Temporary cached files and pages - Tried both Default and Max protection for DNS over HTTPS - FireFox is allowed in Windows Defender firewall - Tried setting 'browser.cache.disk.enable' to FALSE - Tried changing 'Enable HTTPS-Only Mode in all windows' to 'Don’t enable HTTPS-Only Mode' - Windows and FireFox are up-to-date

None of the above saw any improvement in loading time.

On certain websites, I see that the background color of the new tab page replaces the default background color making the content unreadable, example:

If I browser this website: https://typespec.io/docs

Here's what I see (see the firsrt attached screenshot). Now, if I open the same URL in Private browsing, the background color changes too (see the second screeenshot). In the 3rd screenshot I'm adding the reference rendering, that's how I expect this website to render (Edge).

In the screenshot 1 and 2, the background color is exactly the same as the one used by the new tab page when I open a new tab.

Questions: 1) Why is that? 2) Can I change that?

Context: I'm trying to switch to Firefox (from Edge)

I recently updated to Firefox 131.0.3, having signed out of my Firefox/Mozilla account. Now I am trying to sign back in. After a seemingly successful sign-in (with email and pw, followed by "authorization code"), I'm taken to my account page. Scrolling down to Connected Services, I can see a recognizable account name (my Windows 11 user name and the name I've assigned to my computer). But looking up at the account button at the top right of Firefox, I see a small yellow triangle. Clicking on the button, I'm told "Account disconnected." (Remember, I'm currently looking at my account page, which says I'm connected.)

So I try to log in again. I give email address and password, and authorization code, and I'm in again. Now I see an addtional account connected, "Firefox 131, Windows 10" (remember, I'm using Windows 11).

So looking up again to the upper right at the account button, I see the yellow triangle, and clicking tells me once more that I'm disconnected, even though I have my account page open in front of me.

All of this, of course, prevents me from having access to the sync function. I've been through this circle several times with the same strange results.

Anyone have any idea what' going on.

Screenshot attached.

Thanks! Lance

How to search for installed (both enabled and disabled) addons extensions in Firefox browser like chrome does via "chrome://extensions/" in 2025?

It is quite surprising that in 2024-25, firefox still doesnt have any option to search for installed addons via "about:addons". You can only search for addon site, not for those installed on your device and profile and browser.

Is firefox team really updating their browser for 2025 when compared to chrome?

Hello, I have 3 PCs. One is Windows 10, Firefox 131.0.3 One is Windows 10 firefox 131.0 One is windows 11 firefox 131.0.3

All 3 PCs are running BOINC, using the remaining CPU power up to 100%

On PC W10 + FF 131.0 and PC W11 + FF131.0.3 BOINC and FF share the processor time up to 100% On the PC W10 + FF 131.0.3 when FF is dispatched, no processor time is assigned to BOINC and CPU busy is no more 100%. This situation occurs frequently and can last several minutes.

I have been using Linux Mint 21+ since May of 2023. At that time I set all the Firefox preferences settings to what I've always set them to in the past, and have run Firefox with them ever since then. Now, about 3-4 weeks ago, I started Firefox and it came up with ONLY blue lines of text (not graphically). My Firefox homepage is "isp.netscape.com". I've waited until now to report the problem, since I was hoping that later Firefox updates would fix itself, but this did not occur with the 3-5 Firefox recent updates.

Originally, I posted the problem to the Linux Mint forums with the following title under SOFTWARE & APPLICATIONS: Firefox browser no longer graphical but only lines of blue text

Somebody there advised me to start Firefox in safe mode, which I did with this command in the terminal: firefox -safe-mode

and to my surprise, Firefox then came up graphically once again. However, going through the Firefox preferences and setting them one at a time, I came to what is causing the problem. Setting PRIVACY & SECURITY -> BROWSER PRIVACY -> HISTORY: "Remember History" to "Never Remember History" forces Firefox to reboot and when it comes up it came up with only blue lines of text, and not graphically.

One responder to my post on Linux Mint forums stated that it was also a problem with her on Windows 11. So, this is not a Linux Mint, or Windows 11 issue, but a Firefox issue. Mozilla made some change to Firefox back 4-5 weeks now that all of a sudden made Firefox come up in blue lines of text, and I changed nothing with Firefox since started with Linux Mint 21.3 1.5 years ago. I will add though, that ONLY my Firefox homepage (listed above) is the only page that is affected by this, every other website I visit comes up graphically.

What's UP?

I have a Dropbox Paper document that I use for my bookmarks. It lists the name of the site (with link attached) and hints as to my username/password for any given site I use.

For years, it has worked just fine, but trying to solve a different problem, something happened (in my settings?) that renders those hyperlinks non-working. When I click on, say Facebook, it formerly took me right to FB. NOW it gives me a weird yellow box in the upper right corner that says "about:blank" in the upper left of the box, and 3 white boxes at the lower right of the yellow box "Allow" "Deny" "Close." If I click on "Allow," I get a blank page. My navigation doesn't seem to recognize the links I've placed in the Doc.

A friend on FB posted a link to a YouTube video and when I clicked on that, I got the yellow box with the proper URL and a white box option to continue. I've tried to recreate that particular box, but, apparently, once it's accepted, it's OK from there on out.

I have tried deleting the link from the Paper Doc and reinstating it, and I still get the yellow box.

What have I done and how the heck do I get rid of that yellow box?

At some point in the last few weeks -- possibly after an upgrade -- I've noticed that some websites such as the Washington Post and Fidelity can take minutes rather than seconds to load. The problem doesn't seem to be with the sites themselves (because they load fine on Chrome) or with my hardware (because exactly the same thing happens on both of my computers). Has anyone else noticed this?

( I'm running Firefox 131.0.3 on Windows.)

Hi,

My mic will not connect to anything with firefox. when on the individual web pages it says mic is allowed but the websites won't detect any microphone. i've tested this with discord and a handful of voice/pitch training websites, the results are always the same. it says the mic is allowed but the website won't pick it up

i've tried clearing my cache and the other recommendations i could find online like allowing autoplay, it still isn't working. i am on a mac using an external microphone and i've already made sure firefox has all mic permissions and that the mic works by testing it in the apple mic test thing as well as with other applications. this problem only comes up with firefox. i also disabled any privacy/security addons (i have ghostery, privacy badger and ublock origin, all currently disabled)

this is very frustrating and i truely don't know what to do about it, any advice would be greatly appricated

One of the things I heavily rely on with FireFox is it storing words I type in reply boxes on various forums. Lately however, Firefox only seems to keep them for several hours, then they disappear. For example, I can type in "K Frame." (See image attached) The next time I go to use that field again, that text will automatically appear. And it may continue to do so for several hours, even if I close out Firefox and return later, but eventually, within 24 hours, it will disappear and I will have to retype it again the nest time I want to use that phrase. FireFox used to hold these words or phrases forever.

Any suggestions????? Both my Windows 11 and Firefox are up to date.

The problem I encounter has happened since I begin to use Firefox on Windows 11. The same problem happened to my Macbook as well, but a workaround is available. While with Windows 11, I can't find the solution anywhere on the web. Whenever I type on the browser, if I write a non-character notation right behind the word (like "this,"), the word would usually auto delete itself or sometimes, the word clone itself out (e.g, wordword, thisthi, etc.) or it deletes a small section of words right behind that non-char. I don't have insert turning on. I am quite uncertain whether you can reproduce this error on your laptop (for me, I have been through 2 windows 11 laptop and this error still persist). This error seems to only occurs for Vietnamese (Telex and VNI) default keyboard from Microsoft, Russian and English work fine. I suspect that it is caused by Microsoft Vietnamese, but I have unchecked all kind of spelling checking on settings. So should I use a third-party Vietnamese language typing for this situation or does it caused by something else?
