منتدى دعم ”Firefox“

when playing videos, firefox makes the videos much darker and higher contrast than the original videos, as well as maxing out the cpu on my laptop when playing video, started a day ago or so.

Please excuse me if I miss any details.... this is my third time trying to submit this issue.

I will just skip to the meat of it this time. I'm getting this error while working from my localhost. I have been working on a personal project for years with this set up with no issues until today. I can no longer click on the errors in the console log and be directed to the Debugger tab. When I click on errors, nothing happens. If I try to open them in a New Tab, I get the error below:

The address wasn’t understood

Firefox doesn’t know how to open this address, because one of the following protocols (webpack) isn’t associated with any program or is not allowed in this context.

   You might need to install other software to open this address.

I have also noticed firefox does not even load all the files until I refresh it at least twice. Even when it is all loaded properly, the error persists.

I have tried: - restarting firefox - restarting my computer - clearing ALL cache and cookies - running firefox in safe mode - disabling all add ons - disabling performance mode (was already off) - checking network.protocol-handler.external.javascript = false (it is)

Let me know if there is any other information I can provide. I really dislike having to work in chrome for this so I hope I can find a solution as soon as possible.

I have a few websites, among them glovoapp.com and work Kibana, that don't open properly in my regular Firefox session any more even though I tried to remove cookies related to those websites and anything else I could think of. They work fine in private window but it means I have to authenticate each time. What steps do I need to perform to completely clean a website settings from Firefox memory?

In case of Glovo (and several other websites) in regular Firefox session there's an error: Content Security Policy: The page's settings blocked the loading of a resource at inline ("script-src"). Same doesn't happen in private window.

In case of Kibana (and several other websites) in regular session Firefox somehow remembers old authentication - it doesn't ask for new credentials and doesn't send Sec-Fetch-User header (which results in Kibana throwing HTTP 405 Method Not Allowed). In private window the header is sent correctly.

I'm using Tridactyl so I tried to use the :sanitise glovoapp.com command which, in theory, should remove everything that can be removed with API calls as described on https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/browsingData/DataTypeSet - it's not enough.

Prior to Version 113.0.1 I had No problems with all my web sites. Now, I have major issues. From not being able to log on to having to close the browser totally because Firefox won't allow me to go back to the site's home page. I know this accurate as I can log on to the sites via Safari and No problems and the sites work correctly.

I've been using Firefox for many years without a problem and have always liked it, but I've recently starting encountering a problem where Firefox consistently crashes after closing. After I close Firefox, the Windows Task Manager shows it still in memory. After a couple of minutes, the Mozilla Crash Reporter screen pops up informing me that Firefox had a problem and crashed, with an option to restart Firefox or Quit. I tried refreshing Firefox, which was a challenge because of the problem of hanging in memory after closing, but it did not resolve the problem. I also tried uninstalling it, then deleting the Mozilla folders and clearing out any references to Firefox in the Windows registry, and reinstalling it. I haven't installed any extensions yet; but sadly, I continue to encounter the problem. Any ideas about how to resolve the problem?

I should mention that I had bought a new SSD for my computer and migrated everything over from the old SSD to the new one. The problem with Firefox began after the migration. Everything else that was installed there works without a problem. I would be surprised if this is related to the issue considering I've reinstall Firefox.

Since `monospace` means something diffrent on every device, and I need consistency between clients I use `Roboto Mono` on my Website as ASCII-Art font. For some reason Firefox on Windows cannot render the font properly (view image). What can i do to fix this? The problem presists across my desktop and Laptop. See for yourself https://nx2.site/my-ascii-art (I cannot guarantee this is always up + In the future it's hopefully fixed?)

Hi. When opening the Microsoft Website (answers.microsoft.com) i experience some memory leaks. See photo for details.

Someone knows why?

Last Tuesday, Win 11 AND Firefox both updated on the same day, Firefox to 113.0.1. Ever since, my Firefox has experienced SIGNIFICANT lag time loading even the most basic of websites. It feels like Netscape 1.0 slow (yes, I'm that old). I've disabled 2/3ds of my addons to see if that would help and it hasn't. I don't know if it's an issue with the Win 11 update (KB5026372), with Firefox or some combination of both, but any help in addressing this issue would be greatly appreciated.

I been having problems with firefox using up most of my cpu while browsing some websites and it doesn't even load as fast as before. This has been happening for a few days now. Prior to this, firefox was fine and loading pretty quick, but these last few days have been painful.

Thinking that was a small bug, i restarted my computer. Before opening the firefox again, I opened up task manager to check how much resources will the browser be using. Before that usage would be normal and not even close to high, but opening firefox and waiting a few seconds to let the home window appear, the task manager showed that it was using all of it still.

I browsed some other help questions on this website and disabled "Use recommended performance settings", because that was one of the solutions on one of the relevant questions. But even that didn't do reduce resource usage either. Is there any way to fix this or will I have to suck it up and suffer with slow loading?

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

For the past few weeks, Firefox has started crashing when logging into various websites. I've updated Firefox, cleared cookies etc, reinstalled Firefox, opened it in Troubleshooting mode, updated my OS, disabled extensions... everything I can think of. After some sleuthing, it seems to only happen when trying to log into a website. Doesn't happen on every site, which is weird.

This is so frustrating, please help!

Hello all. Since the update to Version 113.0 I have been getting an error in my Event Viewer which is Event 2 Firefox Default Browser Agent . I am now on Version 113.0.1 and still get this error. Firefox is my default browser. Below is an image of what I see in my Event Viewer and also the full view of the event itself. I seem to not be having any problems with the browser but I was wondering if anyone could shed some light on why this is happening or forward to the Devs.

Respectfully, Don

I run Firefox on a #Windows 10 Dell laptop. I have a question and a problem, both of which involve Private Browsing.

Question: Does Screenshot work in Private Browsing? If so, how do I enable it.

Problem: When I'm in Private Browsing, my headphones aren't recognized; in normal browsing,the headphones are recognized. is this a Firefox problem or a Dell problem?

Thank you.

Hello. When I paste something inside firefox, then firefox suddenly shuts down and after that a window pops up, informing me that firefox has crashed and asking if I want to load the previous session... No changes have been made to my computer lately. Firefox has been updated to 113.0.1 but the problem has not been solved. Any suggestion?

Thank you.

After updating from version 112 to 113 - performance has dropped dramatically.

In the beginning the performance after the update was faster than before. But as of tonight and today it's much worse than it was before the update.

I noticed that the browser started using more CPU than usual. Ryzen 7 5800X3D.

Cleaned cache already two times - didn't help. Tried Safe Mode - didn't help.

I just upgraded firefox to v 113 64 bit with windows 7 ultimate. Now when I watch youtube in fullscreen there's a border around the screen. i don't use picture in picture and it isn't on yet the border won't go away no matter what I do. Please fix this or i will use another browser. i will include a screenshot from youtube in fullscreen mode look at it.

Some pages were crashing before, now that I have updated to 113, happens on almost any page. Same problem in troubleshooting mode, so not an extension, plug-in, etc. Attached troubleshooting info.
