Firefox supportforum

Firefox use a lot of CPU time ( it reaches 100% ) while watching youtube videos in 720p on Windows 10, and videos lags and stutters too much. Not using any ad blockers, non of plug-ins are on. It does work just fine on Ubuntu on the same machine Vids also were working fine on previous popular web browser known for its spyware

Using hardware acceleration is on in browser settings. Specs are: CPU: Intel(R) Core(TM) i5-3230M CPU @ 2.60GHz 4,00 GB x64 Windows 10 Home edition 22H2 GPU: NVIDIA GeForce GT 635M

Firefox version 120.0.1 (64-bit), up-to-date

The "Layout.css.page-size.enabled" configuration parameter = False ,worked effectively in previous versions, but after updating to Firefox 119.0, it no longer works whether I set it to True or False.

Orientation option is missing when I try to print documents from a website. The Firefox Print Preview window, which usually allows orientation choices for printing, is now not available.

Please advise. Thanks!

Firefox 116.0.2 64bit on Windows 11 Pro 22621.2134

I noticed today that a video hosted on the website Reddit has subtitles on it. When I view the video in other browsers it does not have subtitles. Why are subtitles being generated in Firefox for this video? Is there a way I can disable these subtitles? While often useful, the subtitles in this case just get in the way.

If URLs are allowed one example is here: https://v.redd.it/z7tekckuy9hb1

Thanks.

Firefox has been very slow loading all web pages for many months. At first I thought it was my ISP until I tried different browsers, Chrome, Brave and Edge are very fast loading web pages, so it's just Firefox. Firefox loads slow too, other browsers load fast.

I saved my bookmarks then completely un-installed Firefox. I searched for and deleted all folders named Firefox and Mozilla. I re-installed Firefox but did not import my bookmarks or add any extensions or themes and Firefox is still extremely slow.

I also tried DISM and SFC on Windows 11 but no problems were found.

I've been using Firefox since NetScape closed and I am very familiar with Firefox.

Any ideas or suggestions will be greatly appreciated.

I get this error when trying to access my email using FireFox. Lately this (or a similar) error happens weekly if not every couple of days. Always first thing in the morning, too.

my email works just fine using Safari so I am at a loss.

I have tried running FF (Firefox) in safe mode, ensuring outlook.live.com is an exception to the pop up window blocker, changed default protections on outlook dot com to none from standard.... Turned off ABP, clearing cache and cookies from within FF.

it may be worth mentioning that I can still browse/access other websites while outlook produces this error, and my network settings within FF are set to use default system settings (no proxy).

Firefox with only this tab I am submitting this to, NO extensions as it is a brand new OS/machine, memory over half gig, in firefox task manager, GPU is over 300mb. This makes the browser literally unusable, tried resetting, renaming the profile file, logged in with my account, turned off hardware acceleration, rebooted the machine, nothing works...

Since the Firefox update released 2 days ago (version 115.0.1) I'm constantly having an issue which causes the video to stop playing after the adverts. I eventually get a video unavailable message. I've cleared my cache but it's made no difference. I'm hoping that this is a known issue & that someone is investigating ?

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?

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

Youtube, sometimes, loads for ~5-10 seconds on average for no reason, doesn't load the video or audio at all. Extremely frustrating when I'm just browsing, it may not seem like a long amount of time but I shouldn't have these issues to begin with. Cleared cache, no addons are out of date or tamper with Youtube. Tried every fix I could find on the matter, nothing seems to have worked. Issue persists. I had similar issues with Kaspersky AV installed, so I had just uninstalled it. Prior to this newest firefox update, I have had no issues at all.

I'm getting a "Secure Connection Failed" error when I click on the tabs. Other browsers are working. This just started this morning when I got on my computer. How do I fix this problem?

A few days ago Ubuntu (22.04 LTS) showed me a message saying I can upgrade my OS (or something along those lines). I click on agree (any button that would let me proceed) and the upgrade took place (without restarting). Along with the upgrade Firefox was also updated to its latest version at the time (119.0). Since then, videos on Twitter play but without sound. On some other websites also none of the videos play. On YouTube, Firefox shows me a message saying "To play video, you may need to install the required video codecs" but the videos play fine; I haven't tried other websites but I assume all would have some issues. Google Chrome however doesn't have this issue and all videos play without any issues.

Note that I have not restarted my computer since the upgrade. I doubt this could be an issue but please let me know if you think this could be the issue.

I did the followings and restarted Firefox but none have worked so far for Twitter and some other random websites that I come across, but they resolved the issue for YouTube and now YouTube videos play, although I still get that codec message at the top of the tab:

sudo apt-get install ffmpeg sudo apt install ubuntu-restricted-extras sudo apt install libavcodec-extra

Someone told me this is because the default Firefox on Ubuntu 22 comes as a snap package and I should install the APT package manually instead so that it works. I prefer not to do this because I have lots of tabs open and have manually changed lots of the settings (including in about:config) that I want to preserve. I would also like to preserve the history of visited websites and keep the current cookies (don't really want to keep entering username/password on the same websites again). So the best way for me is to fix the issue for the default Firefox on Ubuntu 22.

Could you help me figure out what I should do to fix this issue?

Hello! So the problem I'm having is every so often after ten minutes of Firefox working perfectly it will stop working. For example, it won't load any new pages it'll just be stuck pinging back and forth. The website will stop loading YouTube and Twitch will show network errors etc. And it's NOT MY NETWORK or router.

I'm hooked up threw an ethernet cable but my CPU and ethernet ( I just got a new ethernet cable CAT 8 because I thought it was my cable but it still doesn't work) only spikes when using Firefox it's like Firefox stops sending and receiving. Yet other browsers like Chrome work PERFECTLY. But I would prefer using Firefox since all my bookmarks and things are saved here.

I've tried clearing my cookies etc. I'm going to try redownloading Firefox but if there is anything else I could do please let me know. I have some images attached one of the balls just loading and I'll be waiting forever until I restart Firefox. The other is of a media player that says I have a network error but I only get this error on Firefox.

Thank You

I now have 115.0.3 and this problem still exists. It was reported right after 115.0.1 was released. When watching FreeVee on a Windows 10 desktop it stops a short while after an ad plays. It looks like it loses the ability to stream the main movie while streaming the ad. After the ad it plays about 20 seconds of the movie, probably what was in the buffer before the ad started, and then it freezes. I get the circle wait icon, like what typically happens when the Wifi goes down. After a while a message appears saying the Internet is not working. See attached image. Then I get the message (see other attached file) saying Video Unavailable. We're experiencing a problem playing this video. For assistance, please go to www.amazon.com/videohelp. Close Player.
