Firefox Support Forum

Everytime I try to close my Firefox browser window, it just stops. There are multiple processes taking in excess of 200 or 300K in memory that seem to be causing the problem. I have to manually end the process just to close Firefox, and it is quite annoying. I just checked, my Firefox is up to date. Yesterday I deleted and re-installed Firefox, but it's still doing the same thing. This is kind of driving me nuts to be honest. I have Chrome, Opera, and Edge also installed on my computer so I'm ready to jetisson Firefox but thought I'd see what the community has to say first.

UPDATE - Firefox worked great for a few days but the issue returned not too soon after that. Whatever happened in the last update was only good temporarily. I've already done all the initial troubleshooting steps and believe I may have discovered the root cause of the issue.

There are multiple processes in Firefox whose size is over 100,000 kilobytes in size. Some are over 200K, 300K, and 400K.

As I compare this with other browsers I have on my computer, Edge has no processes over 100K, and neither does Chrome or Opera. I believe this is not coincidence, there is something internal to Firefox which creates large processes that is causing delays in closing it. Once again the problem has started annoying me and has started giving me thoughts of switching browsers again.

You can see it in the screenshots I posted.

Ref Firefox Ver 84.0.1 OS > Win 7-64 Dear Firefox Support,

 I have already contacted MS support about the subject issue and they were no help.

I am trying to find out what is causing the issue and how to get rid of it.

 I can't be sure but it may be caused by a Microsoft "START" App.  The issue appeared

to begin about two weeks ago, so it's obviously caused by something new, which may be Microsoft related. Below is Dropbox link to a screen capture of the issue.

 Any tips for ridding my PC / Firefox browser of the issue will be greatly appreciated.
 And thank you for the superb browser.

Best regards, Ken Boardman > elsmoko@cox.net

I accessed the RedHat 7 Administrator Guide (in PDF form) from a RedHat web page. Firefox shows it as 603 (or so) pages long. If I print it from my Windows 11 Acer laptop from Firefox, somewhere between 40 and 58 pages print. The times that Firefox pretends that the document is 58 pages long, there is an error pop-up (attached) - an error message that provides absolutely no useful information. Other times, there is no error message, but only the first pages of the document print. In "normal" (not debugging mode), the Windows 11 printer status page shows the page status as a fraction, with the denominator climbing as Firefox seems to be stepping through the pages of the document, and with the numerator seemingly climbing as pages are sent to the printer (on my LAN). The denominator stops at between 40 and 58 pages. If I run Firefox in debug mode, the status shows only one number. Judging by its speed, I assume that it's the number of pages sent to the printer. If I copy the same pdf document to, say, my CentOS Linux 5.8 box and print it with lpr, the entire document prints. If I open the document (on the WIndows 11 box) with Bing, it prints many pages. [I stopped the print job after 70 pages or so. I don't KNOW if it would print the whole document, but it gets farther than FIrefox does.] It doesn't matter if I print from the Firefox print dialog or the system/driver one. And, both are set to print ALL pages of the document.

I know this has been addressed before, but I cannot find a solution that resolved the problem. Firefox is using a high percentage of ram and setting up individual resource demands for each tab. I have cleared the cache and refreshed Firefox with no resolution. At times this will freeze my computer if I have a lot of tabs open. I have compared the tab resources between Firefox, Avast Secure Browser and Edge. The other two use no where near as much resource.

I am running a Lenovo P1 I7 processor with 16GB RAM

Attached are images of the resources from both about:processes and Advanced System Care.

Any suggestions is appreciated.

Firefox is showing all the time "The connection has timed out. The server at xxx.localhost is taking too long to respond." on loading or changing pages on localhost. When calling the same URL everything runs smoothly using Chrome.

Environment: Firefox 111.0.1 / Ubuntu 24.04 / Apache/2.4.56

Which settings can I change in Firefox in order to solve?

After a mistaken forced restart (inadvertent pressure on the shutdown/start key), one of the 3 windows I had open is invisible. It shows in the 'Windows" menu as one of 3 but when I select it - nothing. It does not show as a recently closed window in History. I have restarted Firefox multiple times, including deleting the xulstore.json file then restarting (a fix from another similar thread).

How can I restore this inaccessible window?

Thanks

I recently moved into my partners parents house temporarily and their ISP set up is less than ideal but usable. Since moving in we've had a few hiccups with the internet and initially narrowed it down to google searches.

The graphs below are my internet activity with a couple tabs open and a stream to just get a consistent graph for pre-googling and then post-googling, the connection hitching continues until i close and reopen firefox which obviously is inconvenient. (I've been making do with bing in the meantime and it is really beyond parody how bad it actually really is.)

On a whim today I tried googling something in chrome to see if it'd do the same thing and it doesn't, which is great because this went from just a bizarre isp issue to a potential bug which can hopefully be fixed.

Hi everyone, I always had this problem in firefox: some extensions don't load during the first visit to a website but only after I reload the page, for example I get that the SponsorBlock extension doesn't load when I open a youtube video for the first time, probably this problem occurs on extensions that operate on specific sites like youtube, twitch because with extensions like uBlock I didn't have this problem. I have tried activating the extensions I have one at a time but the problem still occurs

I have an issue where I can upload a video to OneDrive and it plays back at a very low resolution in Firefox, both via double clicking and using Stream. The problem persists in safe mode. If I download the video, it comes back at full resolution and it streams perfectly in Chrome and Safari.

I have cleared cached web content. I also recently had an issue with lip sync on YouTube, which I resolved by refreshing Firefox, but the above remains.

Any ideas?

I have been using firefox for a while but recently stopped working at first i thought it was connection issues, but, that isnt the case. I have had to update my mac to macos monterey 12.6 and firefox refuses to load any website. Keeps saying the connection has timed out and following message:

. This site could be temporarily unavailable or too busy. Try again in a few moments. . If you are unable to load any pages, check your computer’s network connection. . If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

It's frustrating. Any help on this please?!

Hi, After formating my computer I have problem with videos in FF (facebook, some YT videos and others). Alwasys getting message : "The video playback was aborted due to a corruption problem or because the video used features your browser did not support."

I tried: 1)incognito mode 2)clearing profiles 3)wiping whole FF and still no fix.

I'm using 111.0.1 (64 bit) version. Videos working well on my laptop wish same FF version. Any ideas how to fix it?

Hi there,

When using my Thinkpas X13s trackpoint to scroll 'sideways' with the Trackpoint+middle mouse button (i.e. from left to right) a new blank Firefox window opens up. So, when trying to scroll downwards all is well but the slight deviation and Firefox opens many new windows. I mean, many (like 5, because of the 'continuous' scroll).

Community solutions have as of yet not brought any luck. Any help is appreciated, thanks.

when I open firefox it ALWAUS goes back to the last page I visited. I checked off that feature in settings, tried restaring in safe mode, refreshing firefox, updating, reinstalling, nothing works. I DO NOT WANT LAST PAGE RELOADING AT STARTUP. How do I make firefox works properly?

I need Web3 functionality for my applications. Will there be any updates without having to change browsers to Chrome? How soon will this take place?

Thanks, [email removed from public]

I'm running Windows 11 on a new machine. Doing a process check shows Firefox is currently at 853MB ! I have two windows open. What is going on? What happened to "Run lite without overbyte"? (Yes I'm was a Dr. Dobb's subscriber, )

I'm running Firefox 111.0.1 on a 2021 MacBook Pro running OS 13.0.1. I'm suddenly unable to load eBay; all efforts result in a blank white page whose tab indicates it's trying to load. I cleared my cache of all eBay data and restarted Firefox--alas, to no avail. Please don't tell me to look for the shield in the upper left-hand corner--one needs to have a loaded page in order to do that.

Incidentally, I REALLY appreciate not only being informed that my Subject field needs at least five characters but that as it stood, "(it has four)." Thanks for assuming that I lack the inability to handle single-digit cardinals.

scroll bars cover website-widgets (check boxes) (110.0.1 64-Bit)!! e.g., when trying to activate a checkbox at the right edge (Amazon, marking an item to cancel an order) that is not possible because the firefox scrollbar (right side) covers the Amazon checkbox, so it is impossible to mark it, and so the order cannot be cancelled!

This is an unacceptable malfunction!!

(OTOH, on MSEdge, the scrollbar sits to the right of the checkboxes without ever covering them, so it's obvious that this is specific Firefox malfunction!!!)

Hi! For the last ~3 days I've been having a problem that is getting increasingly frequent where tabs will, sometimes even after having previously been loaded and sometimes brand new tabs, turn blank and feature only a small loading animation at the centre of the page.

Reopening the url in another tab doesn't work, but the sites will work on Chrome and it's not limited to any one website, it's happened with youtube, google, reddit, fb, random blogs etc. Sometimes it will even happen in the middle of using a website.

I haven't added any new extensions since before the troubles started, and I tried disabling them all to no avail. I'm not really sure what's going on, though I am to assume that the pages are somehow hanging but I checked the processes page and it didn't seem to be an issue?

Any help would be greatly appreciated. I'd rather not have to move back to chrome.

Previously, I raised an issue in this post https://support.mozilla.org/tn/questions/1390310 and unfortunately, it's still persisting. I usually keep three Firefox windows open, and my downloads are primarily done in the second window. However, when I click the download button, nothing happens. The download button works perfectly fine in windows 1 and 3. This issue has been causing me frustration for some time now, and I have included all the details in the other post. Kindly check it out.
