TO MOZILLA DEVELOPERS

In spite of hundreds if not thousands of users reporting this issue over and over again, and your suggested workaround to reduce memory usage in the settings that doesn't do anything - FIREFOX is still using unacceptably HUGE amount of memory.

With just FOUR (4) tabs open in one window, in the Task Manager I can see 17 (!!!!!!) Firefox windows open using 830 MB of memory. The highest usage of all my apps including memory hungry media apps. It's using THREE times as much memory as my Adobe Audition processing edits of a 1.5 hr audio with several clips.

This is insane!! You have gone crazy with caching to the point of making this browser unusable.

It's freezing up and crashing my Audition so before I work in it I must shut Firefox down completely - and I work on a powerful tower PC designed for media.

If you don't seriously cut back on this insane caching for the sake of browsing speed IN THE NEXT UPDATE, I won't be using your browser at all, it's simple as that. I'm already migrating my bookmarks and setting up Chrome which uses about half the memory that Firefox does with the same tabs, and I suspect that many users will follow suit.

The workarounds you offer DO NOT WORK. Any app that uses more than 500 MB of memory at any give time on my computer - goes.

I keep getting alerts from Norton while browsing ran Norton's scan and MBAM then ran Norton's Power Eraser. I did not fine the source of the problem. I added an entry to my hosts file hoping it would block the IP but it doesn't seem to work, I may have done something wrong. The entry I made is: 103.224.212.246 0redird.com at the end of the hosts file. Below is the log from Norton security, the full URL is very long:

After start up Firefox I am not getting any audio. No other app nor browser has this issue. It does not show up in the volume mixer. I've made sure all apps, browser, drivers, and windows are up to date.

I am using Firefox 125 in Windows 11. And this just happens recently.

Sometimes, quite frequently, when I click the addressbar wanting to input or select a new address. The Firefox UI freezes (before the dropdown list of addresses is shown). The video/audio/other effects are still working, and from task manager, it does not cost more CPU/mem than usual. But it does not response to key press or mouse action. All I can do (that I know of) is killing the processes. The problem does not seem related to "current" webpage I am browsing. And I have not installed new addons for a few months.

Any idea what should I look into?

Do you (as a Mac user) experience the same or similar:

44 instances of FirefoxCP Isolated Web Content ranging from 60MB-918MB each, with 18 of them above 200MB and 5 of them above 400MB. I have 15 tabs open and in practical terms almost nothing else open on the computer (a brand new M3 silicon iMac). It has 8 GB of memory. I had similar experiences in the past, but never as bad as now. I do not know everybody else can live with this.

Is this how Firefox is designed to operate or is this a bug?

Thanks.

On bootup firefox opens a single window which says the following:

Sorry. We’re having trouble getting your pages back." We are having trouble restoring your last browsing session. Select Restore Session to try again.

The restore function succeeds in restoring 6 windows from the prior session, but this notice keeps appearing on every bootup.

Here are a few relevant details from about: config

• browser.sessionstore.max_resumed_crashes (is set to 1)
• browser.sessionstore.resume_from_crash (is set to true)
• No 3rd party third party cleaning software
• Two extensions, tab stash and tree tabs
• There are no entries in about:crash for this event

Have been using Firefox from 2004 with 5-10 open windows which appear on bootup as they existed from the prior session. This is the first occurance of this error. Appreciate your support. Here are a few system details:

1.) 28gb ram 2.) Linux ~ LMDE 5 (Elsie) 3.) Firefox ESR 115.8 (oesr) 64 bit.

Since the last FF update (115.5esr, Windows 8.1 Pro) I keep getting the following error message when I try to access one particular website:

The page isn’t redirecting properly An error occurred during a connection to www.doordash.com.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

I have tried virtually all the solutions suggested online. I have cleared my cache, deleted cookies and site data, and I have tried to access the site using Troubleshooting mode, all to no avail. I contacted support for the particular website and they have no difficulty accessing the site with FF.

I can access the site in question with the Chrome browser, so the issue would appear to lie with Mozilla. I use this particular site frequently and would much prefer to continue to access it using it with FF, as I have done for over a year. I just installed Chrome on my Windows 8.1 Pro PC solely for the purposes of accessing this one website.

Help in resolving this issue would be greatly appreciated.

I have been receiving the following error code 'PR_END_OF_FILE_ERROR' on several website on my Firefox browser. Sometime, not all the time, I get the same error message while trying to use YouTube, while other times the site loads but says that I am offline and no internet connection. I have done all of the fixes that they say to use online and nothing seems to work. YouTube will occasionally work but none of the thumbnails will show up. Then there are other site that work fine.

Hello. I don't know which Firefox release broke this essential feature. The problem started after I enabled Aero in my Windows 7 system. It happens often if I have an open tab with https://www.o2tv.cz/ which uses some DRM to play TV content.

Firefox 115.12esr slow to startup takes up to 10 second to load the first time now Firefox was fine in version 112.esr. to bad Firefox forces updates, even when the update make Firefox worse. https://snipboard.io/QF0ERT.jpg of course it works faster without extensions, that does not mean anything. I would reinstall the older version but Mozilla fixed so we cannot. I do not have time to reinstall all the extension so I am left with a useless Firefox. To bad Firefox does not allow reinstall of extension automatically, a reset of Firefox would also make Firefox useless; I am at a loss to how to continue to support Mozilla and not switch to another browser?

I was watching anime today on some site and my firefox was downloading many files without my knowledge into my download folder. I'm worried that it can be some viruses? This is a screenshoot. Should i be worried? Thank you for help.

Dear Support Team,

After updating to last Mozilla Firefox version (126.0.1) all my ngx-datatable tables are overlapping all rows over the first one even if the entire height of the table is correct calculated.

This is a blocking point. I need assistance urgently.

There was no such problem before, after the 117 update, the CSS theme I use is constantly reset and the browser returns to its default theme. The screen goes black for a moment and then the theme resets or the browser crashes. Is there anyone who has experienced the same problem? Any possible solutions?

Using this theme: https://github.com/Neikon/Fox11

I'll add 2 pictures of what my browser looks like when normal and crashed.

My Firefox browser automatically updated a few days ago. Since the update, the browser now crashes repeatedly during basic browsing, making Firefox essentially unusable. For instance, retrieving Yahoo mail, reading articles, accessing login pages -- the page will enter some type of refresh/reload cycle and crash the browser.

I opened the browser in troubleshoot mode and the problem did not occur. Following the Mozilla instructions, I disabled extensions and reopened the browser normally, and the crashes continued. I have not taken any additional actions.

This problem began immediately after the latest browser update on 9/13.

For a few months, I have encountered an issue with videos playback on my browser. On most websites (including Reddit, Dailymotion, and even some videos on YouTube), whenever I scrub back a video, it will stop for about ten seconds, while the audio keeps playing.

My current extensions are: Metamask, Bionic Reader, uBlock Origin, Return Youtube Dislike, and TWP Translate Web Pages. I have tried using Troubleshooting mode, but the problem persisted, so I think it's not because of my extension.

My OS is Opensuse Tumbleweed, with Firefox version 155.0.3. I didn't have this issue with Firefox ESR on my previous Debian 11 installation. I hope someone can find a solution for this, as it is extremely troublesome switching to Chrome whenever I want to watch videos.

I have this ennoying issue since some months and didn't find a way of fixing it, even by completely deleting the app and removing all remnants of profiles before re-installing it. If I leave Firefox open when I shut down my computer, most of the time (but not every time!) instead of opening the last window with its tabs, Firefox displays the KDE Plasma's or OpenSuse's splash screen (which is a lamp bulb on a black background) and no menu). If I minimize the window, and maximize it again, it displays a screenshot of my desktop!... I can't do anything but close the window and re-launch firefox, but then the history of last closed windows is gone.

I have the same version of FF and the same version of OpenSuse on two other computers and never had this issue on them.

I would be grateful to anybody who could give me some tips to solve it or even investigate!

Thanks for reading. Erik

I have noticed for awhile now that when I load my Firefox homepage its keeps taking longer, certainly longer than it used to take. Also, when I load a You-tube video it takes about a minute for things to work properly. The video and audio are erratic and skipping and simply disjointed for about the first minute, but then after that period of time the You-tube video runs OK, both audio and video. Something seems to be causing those problems recently that I didn't have previously. The problem seems to just keep getting worse also. I would appreciate any input and suggestions that may help the problem. Thank you.

Is there a memory issue with Firefox in regards to how PDF files are shown?

This happens every so often.

When I open a PDF the font is distorted and it seems to be encrypted. I have to close Firefox and reopen and then the PDF file is displayed correctly without any issue.

Thanks.

This is a recurring problem. I have just been on to Vodafone who have tweaked my router as my speeds, download and upload, were very erratic, and upload speed often zero so connections failed. Sometimes my phone speeds were similar but not always. The Speedtest by Oopla desktop app also showed erratic results but often when they were OK the web-based test on Firefox was much worse, with upload speed zero. When I started this Firefox showed upload speed zero. Now Firefox shows upload 18Mbps. This variability keeps happening and is driving me spare, as even emails often fail to go through - I use Thunderbird. I shall see how things go tomorrow and tell you how it is going.

I gather there can be different kinds of screen flicker and many causes. My problem is with one particular website, https://www.yucatan.com.mx/ , and it didn't used to happen. When I open the site or pages in it, trying to scroll down just results in continuous, rapid flickering and no scrolling. I have to pull the scroll bar down just enough to get the page started, and then the mouse scroll wheel works. After looking at other people's similar issues, I have tried disabling smooth scrolling and the pop-up blocker. When I open the same site with a different browser and try to scroll down, I do see about two frames of flicker, but it's almost unnoticeable, and scrolling works OK. I restarted Firefox in troubleshooting mode and was able to get it to behave like that other browser at this site -- just a momentary flicker and no interference with scrolling. OK... where does that leave me? I can't use troubleshooting mode all the time. And it's just this one website that presents the problematic behavior. Thanks for your thoughts, -Rick
