Firefox Support Forum

When I open firefox it opens on the "success" page it should open on my selected page Yahoo.com

this happened after I ran the "refresh firefox" option

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.

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!

Our IT specialist at UW-Madison is stumped and suggested I reach out to Firefox. He was helping me troubleshoot why Firefox keeps saying it's sending a code to verify my account, but I never receive the code. He has added the "accounts" email to my contacts and I don't know what else to do or try. Any ideas from the community? I need my bookmarks after upgrading to Windows 11 and can't imagine trying to recreate them all.

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.

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.

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 ?

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

Hi there, Last night I installed some new hardware into my PC, new motherboard and CPU for example. After that, I booted up the PC, everything worked completely fine and I was able to listen to Youtube / Twitch / Spotify etc. through Firefox.

This morning I boot up the PC, everything still works perfectly and I have audio coming from all other sources EXCEPT for Firefox. I have browsed every forum already but can not find anything that relates to me. I can't set my output device, since Firefox doesn't show up in the volume mixer. The tabs aren't muted. I have restarted Audiosrv and Windows Explorer several times. I have re-installed Firefox twice. I have tried booting it in safemode. All of the above hasn't resulted in a single second of audio. I am at a loss.

Kind regards, Siem Hoefnagels

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?

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.

I was on phone for a couple hours last night with my satellite provider HughesNet to figure out why nothing would stream. We never gt it figured out. Then, I tried another browser and it worked fine!

Ihave been becoming more and more disenchanted with Firefox this year. SOOOOOOO many problems, it makes my life harder. The only alternative is Google. Everything works with Google pretty much. BUT I HATE GOOGLE!! EVIL. So please fix firefox!

Hey every time i go to Facebook it keeps going super slow and continues to display the prompt bar where it says this page is slowing your browser down. to speed up your browser stop this page.... well its every single page. and this is happening to me on a couple of computers. I have cleared cache and cookies. I've turned off enhanced tracking. I've also tried opening in a private window and still the same thing.
