I-Firefox Community Forum

Hi, I just replaced my SSD (Samsung 960EVO m.2 250Gb) for a larger/faster SSD (Samsung 980 m.2 1Tb) . I'm on Windows 10 and have 32Mb Ram. Firefox is now very slow on some websites (not all).

This example is typical and has occured on multiple sites. To test and compare, I copied the URL, created a new tab in Firefox, then Paste and Go. I timed this 3 times and each time was 30 seconds. I Pasted the same into Chrome and Edge and each time it was instant. https://savingschampion.co.uk/best-buys/personal/easy-access-accounts

On my previous SSD, there was never an issue of any lag on any site.

BBC.co.uk/news is fine, as are several other sites. Does anyone have any idea what's happening? This is making Firefox unworkable for me, so unless I can fix the issue, I will have to move permanently to Chrome or Edge. That would be a shame after many years with Firefox.

Thank you in advance.

FF keeps replacing

http://mysite.domain.net:3344 with httpS://mysite.domain.net:3344

whatever I try to fix this behavior. Thing is that I own this server and there ever was't any SSL implemented. I mean this - never.

Other browsers (Chromium, Chrome, Opera) don't take such a forcing action, website opens like a charm. Why FF thinks it knows better which URL I really want to open?

I already googled _a lot_ in order to find solution, but no one worked.

Setup: Debian 11 Mate no proxy and no separate "internet security" stuff on laptop (other browsers with default settings confirm that) FF 102.11.0 ESR 64 no addons (all switched off)

already tried: browser.urlbar.autoFill false browser.cache.check_doc_frequency 1 network.stricttransportsecurity.preloadlist false browser.fixup.fallback-to-https false dom.security.https_first false

What else I could do to stop this madness? Thank you in advance for any help

I noticed my laptop was being slow, so I looked at the memory usage. Firefox was using a whopping 5GB of memory on Windows 11. I then looked at about:process and it reported that extensions were using 4GB. I disabled each of my extensions and it still said it was using 4GB of memory. I then uninstalled two of them and re-enabled some extensions and it dropped to 781MB. This is still to much in my opinion, and I want to know how to figure out which extension is being so wasteful. Even a technique on how to figure it out would be appreciated.

in the last day firefox has all but stopped working on most websites. i can go to them and they start to load, but then they eventually break halfway through and either end up loading forever or produce an error. if i look at the console i see "Source map error: Error: NetworkError when attempting to fetch resource." this happens on twitter.com and raidbots.com to name two off the top of my head.

i did a complete refresh and even completely uninstalled and reinstalled the browser - it started working for a bit and then broke again. i have no plugins or extensions enabled currently (i have dashlane but this happens with it enabled or disabled). it's making the browser unusable. ive scanned my computer for malware and cant find anything either. i don't have this problem in any other browsers so not sure what else to try.

I've been lead to believe in previous editions of firefox you could turn off the redirect message and instead just allow firefox to redirect.

However now (as of 112.0.1) i can't find any way to do this. I repeatedly get redirect message and i would prefer the browser just do the redirect instead of having my click a link. I know exactly where the redirect is coming from and i have no problem with it and i don't need it to have a warning.

I'm hoping someone can help with a conundrum.

A few years ago, whenever I first started Firefox--whether I had just started up my computer or had exited Firefox and opened it back up--it would take several minutes for Firefox to load any website (Google, Amazon, weather.com--anything). Once the first site loaded, it would load subsequent sites normally. Interestingly, it was only my default profile that was affected; if I used another profile or created a new one, websites would load within seconds of my starting Firefox.

I finally broke down and created a new default profile, imported my history/bookmarks/etc., reinstalled extensions, adjusted settings, etc. The new profile behaved nicely, loading the first website within a few seconds of Firefox starting. But over time, the load time has gradually increased to the point where it is now behaving just like the old profile: I load Firefox, I try to go to any website, and it takes several minutes for it to load.

Any ideas what's happening/what's the problem? Hoping someone out there has some wisdom and can help troubleshoot. Thanks!

Hey folks,

i am facing issue with high CPU usage on firefox in completely different process other as visible in task manager than my actual process for firefox. is there something wrong with firefox or my system.

This separate process uses more than 60% of my CPU (AMD Ryzen 5 4600). If I close that process in the task manager nothing happens to my current firefox process and i can use firefox normally.

But everytime this separate process starts my system fans ramp up and CPU temps peaks to 70 degrees celsius. and i have to end that process to make it run normally. Thats a quite annoying process to do every time.

I am able to recreate this separate process by:

1. 1. Plug my system for charging
2. 2. I was working offline and connect to internet

both the times the separate process automatically starts and uses very high amount of CPU. I even left my system for 2 hours to keep that process running and complete whatever it was doing. but nothing happend. It continued to run for 2 hours also.

Please find a solution for this. I have already tried solutions provided in the forum:

• Restarting firefox
• Refreshing Firefox
• Enabling hardware accleration
• Clearing some user profile data
• Completely uninstalling firefox and deleting the residual files then reinstalling etc.

but nothing worked.

hello! i've been having an issue with mozilla where webp images are not loading at all. this is especially prevalent on youtube, where thumbnails simply do not load, as well as on tumblr, where if an image or gif is a webp file, it will refuse to load. both are attached in the image below to see the difference between firefox and chrome, as the images load fine on chrome. as well as that, discord, when opened with browser instead of the app, does not load profile pictures, server icons, or custom emojis. google hadn't helped me at all, and i don't know what to do at this point. i don't want to go back to using chrome.

in the attached image, the top images show a set of shark sculptures. the first does not load on mozilla, and looking at the image file, it is a webp. the second image is revealed to be a jpg, which mozilla treats normally. in the second set of images, there's a quick look at a random youtuber's page, the top being mozilla and the bottom being chrome, and you can see the mozilla thumbnails do not load.

thank you for reading! i'm very confused and am unsure what to do. any help is appreciated!

Firefox worked perfectly, but since a few days I can't download anything. I'm using Mozilla Firefox snap for Ubuntu 22.04, version 110.0.1 (64 bits) canonical-002 - 1.0 With Chrome everything works perfectly so I assume it's a problem from Firefox.

When I open a PDF, a MP3 or any file, the "save" option doesn't display anything. Usually it opened a dialog where I could choose the folder where I wanted to download the file, but now I have nothing.

I have only 4 extensions: - adblocker ultimate - duckduckgo privacy essentials - vuejs dev tools - zotero connector

I always had them and I never encountered any problem.

When I try to open Firefox I am getting this error message: Error: platform version '124.0.1' is not compatible with minVersion >= 124.0 maxVersion <= 124.0. Does anyone know how I can fix this? Deb PS I need simple instructions, I'm not terrible techy.

It worked nicely for many years, until today. I installed Supraland from Steam, played for a couple of hours, and suddenly my Youtube page went glitchy - not the layout but minor elements were getting scrambled, especially text. I'll attach a couple of pictures to show it. In fact, all pages glitch if their content changes even a little. As of typing now, I see the glitches, with a word or another getting butchered. Gifs and videos are full of that.

Windows 10, the current update, Radeon RX 580, the recommended AMD drivers installed (and reinstalled again and again, 23.11.1)

I think I did pretty much everything with Firefox. Disabling hardware acceleration fixes it (but then of course the browser goes slow). Games work fine, including Talos Principle 2 which is intense enough. The clean install, reinstall and all that. I'm writing from the beta stable build now. I've tried to regress to the previous versions too.

It strictly coincides with the game installation but I have no close backups - who knew that some game might just do that. Then, of course, I tried to uninstall it too.

Thoughts?

Firefox updated yestarday. I see these changes: extension are gone, theme settings were switched from Dark to Light, "Startup -> Open previous windows and tabs" option went from checked to unchecked. These things are still fine: bookmarks, saved passwords and history. Tried reverting to older Firefox version, but it didn't help so I installed the new one again. I then checked profiles in AppData folder and I see three of them. The problematic one I just described, the one that was automatically created when I tried to downgrade to previous Firefox version and the one which only contains empty "parent.lock" file. There is nothing useful in "Extensions" folders (first profile has addblock extension file which I just installed, second profile has langpack extension file). I don't particularly care about which specific extensions I used since I can just reinstall them when I need them again, but one of those extensions contained custom written scripts which were running on specific sites to help me with my work. Those scripts are what I really want to recover.

Hi.

Ever since I upgraded to version 123.0.1, I am constantly getting slowness on websites stuck in "Performing a TLS handshake..." Eventually the websites load, but it's frustrating. I have read about the various solutions and have tried the following: Disabled IPV6 Refreshed Firefox Reloaded Firefox Disabled and removed all extensions Restart in safe mode Create new profile

This was not happening in version 122 and before. Microsoft Edge does not have this problem, but I prefer to use Firefox. I am running Windows 11 Pro. Any ideas?

Thanks

Hello everyone. Since installing Linux Mint in May 2023 I have been having this issue with Firefox.

Description of issue: When I switch between (or drag) tabs in a Firefox window, the whole window becomes unresponsive, with the last tab I was switching from still in front. Often the contents of the window start to flash (disappear and reappear, leaving a black backgground) every 2 seconds. I can drag the window around, scroll, minimize it, but it is impossible to give any input in any tab. The only action somewhat possible to do inside the window is bring other tabs in front, it is still quite hard for the input to register, and if it does, it takes 10+ seconds. The issue goes away if I close the specific Firefox window, or if I manage to select and drag one tab out of the frozen window into its own new window. Then everything works as intended, like nothing ever happened.

I can reliably cause the freeze-up in a short time by holding CTRL+TAB and drag one tab to change the order while firefox cycles through the tabs in the open window.

While the window is frozen, the rest of the desktop is responsive as normal, even other Firefox windows. If I try to interact with the frozen window I can rarely see spikes of CPU usage. RAM stays at normal usage levels, far from being full.

What I have tried so far that has had no effect on the appearance of the issue:

1) Disabling all extensions i have

2) Run in troubleshooting mode

2) "Create a new places database" as suggested [https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding#w_fi...]

3) Disabled hardware acceleration

4) Creaing a new firefox user profile

5) Use "Refresh Firefox" from the troubleshooting page

6) Use the Flatpak version of firefox

7) Reinstall firefox

Here is my system information

Hello, the description is the same as in the title: Firefox is slowing down significantly while I have "more" demanding games running I'm talking about a game like assassin's creed mirage mostly on ultra for example.

It all started with the purchase of a new computer, on the previous one I did not encounter such a problem. It manifests itself in the way that the video is slightly desynchronized with the sound + I can see a significant difference (delay) when scrolling the pages.

My current rig: Intel Core i7-14700KF Nvidia RTX 4080 32GB of ram running at 6000mhz (G Skill Intl F5-7200J3445G162x16GB ) 2x Kingston SKC3000D2048G 2TB

I understand that the GPU focuses on the game but can't it be improved somehow? The rest of the applications on the computer work normally In my opinion, the computer does not seem so weak that it cannot handle Firefox and the game simultaneously.

Send help please 😊

Automatically hide taskbar in desktop mode => Enabled Firefox => Maximised When cursor is moved to outer edge of screen, taskbar should unhide (Expected behaviour) but in this case it remain hidden (Reality). Firefox along with all other spinoffs give same result. Chromium based browser works perfect, and taskbar automatically unhide itself.

As OLED screen have became common as monitor, Taskbar auto-hide is must. If this issue cann't be fixed I may have to change my primary browser which I used for almost 15 years.

Kindly, look into it. If Chromium can do it, why not Firefox.

I'm running v100.0.1 (64-bit) on Win10. I've seen others report this problem but haven't found a fix listed anywhere. <Ctrl-P> or Menu->Print results in the same problem. The print overlay starts up (say Print in top right corner), spinning wheel above Preparing Preview in the center of the overlay... Never ends. I have to Esc to get out of it. Happens on any page. Print dialogue works fine on same pages with Chrome and Edge.

From today 4 march when I try to record a voice message on chat from facebook appear an error saying an error as occurred. On Chrome it work, from facebook app it work

I even tried other facebook ids and firefox profiles and ever the same. Even disabled the anti popup ublock

In all case I haven't added any conf or adon or other inside firefox, I use same conf as ever and from many years.

Today messages from microphone in chat does not work and facebook say an error occurred Is written in italian but say what I said

Since a week or two my Firefox tabs are crashing more and more often. At work on MacBook and at home on PC.

Deleting the cache and cookies and even starting in Safe Mode are not helping - in fact while writing this very message had 5 crashes meanwhile!

Don't know if you can access the crash report: https://crash-stats.mozilla.org/report/index/4cd570db-d90d-4fcb-aee6-0a1660230818
