Firefox Support Forum

I have been dealing with problems with Firefox and YouTube for a long time. Every time I open a YouTube video in a new tab it would always give me this grey screen that goes away after a long time waiting.

I have tried:

• Refreshing Firefox
• Reinstalling Firefox
• Troubleshoot Mode, which the problem persist in troubleshoot mode so its not an addon
• Tried creating a new profile
• User-Agent Switcher which doesn't work all the time.

I want to avoid going chromium-based browsers but this is making me consider.

When a user opens hh.ru / headhunter.ru (famous HR portal in CIS countries) in Firefox, and then opens dev panel and tries to interact with it, especially with the code inspect tool, the whole browser stops responding.

The problem persists even on a clean Firefox profile. Other browsers (Chromium-based) work well with the dev panel on the hh.ru site.

For the past couple of weeks I have been getting the "Hmmm, We're having trouble finding that site" error screen quite often from both searches and links from other sites. It's always happened once in a while but it hasn't been anything bothersome. However recently it has become quite bothersome because it's happening a lot! However not all the time. It's not completely broken, just mostly. And it's happening while trying to visit sites that I know and visit frequently such as Amazon, Ebay, and even sites for local businesses that I trust and know are working. I'm not having any internet issues with my home wifi, nor am I having this issue with other browsers. I have however also noticed it on my Firefox mobile browser as well. I posted about this a few days ago and got some email back about an issue with my post. If this happens with this one and I'm unable to get this resolved I will just get rid of Firefox on my devices. FF has been a long time favorite and is usually set as my default browser but if stuff like this is going to continue, I can change that real fast. There are plenty of other browsers that work just fine and have decent customer support.

Everytime I load Firefox the bookmarks sidebar is not shown.

Navigating thus View => Sidebar => Bookmarks I can bring it up. It will stay visible for the whole of my browser session. However, after I've closed this session and started another. the bookmark sidebar is missing again.

How can I make the bookmarks sidr be available all the time?

FF 127.0.2 OS Windows 11 Pro v 24H2 Build(26100.994).

So I do not have the settings for cookies or history to be cleared i disabled that and I made sure it should save but no matter what I have to go through the struggle to sign back into everything. I've tried every fix like making a account then signing out or changing the settings nothing has worked. It's really annoying if anyone knows how to fix it that would be great

Hi. Every page I visit I get at least one message popping up with the URL at the top, the message body of "1" and the option for OK. Many pages have multiple prompts for what looks like advertising sites (based on the URLs). Sometimes I get the option to check a box saying "don't allow URL to prompt you again"

Example message for when I go to google: https://imgur.com/a/RBd4mS3

I guess it might be some sort of debugging mode? I tried uninstalling and reinstalling Firefox and it still happens. I am on latest versions: Firefox 127.0.2 on a MacBook Pro (2019) with MacOS Sonoma v14.5.

Can you please help me to remove these prompts? It makes Firefox pretty much impossible to use due to multiple clicks per page load. I've tried searching for help pages but it's very hard to explain the problem to a search engine! Human needed! :)

The password I've been using to access my stored payment methods is suddenly not working. I've tried using my Master (sorry, Primary) password and this doesn't work either

I can't download anything by that green download button (Youtube). I just receive error messages, see attachment. I have read their FAQ and I have latest versions of Firefox and savefrom.net helper.

At some point about 5 days ago, Firefox began to load YouTube videos unacceptably slowly. To begin a video it may take around 30 seconds or more to load (with a black screen and circular loading bar/graphic), and randomly throughout the video it will need to load again which has taken up to 5 minutes at times.

Steps I have taken: - ran Firefox in troubleshooting mode (issue persisted with no extensions) - minimized memory usage - disabled hardware acceleration - refreshed Firefox twice - reinstalled Firefox

Testing/comparing YouTube in Chrome and Edge, videos load near instantaneously (even while running an extension such as uBlock Origin), and I can click anywhere in the duration of the video and it loads in less than a second. Strangely, sometimes the issue doesn't persist for the next 2-3 videos that I try to play, but then goes right back to an extremely long load time for the next video. I've never had such an issue with Firefox before and cannot find a solution. Extensions don't appear to be an issue and other browsers run YouTube perfecty fine.

For about a couple of weeks, there has been a lot of delay between what I type and when it actually appears. It's maddening! I have not changed any of my Firefox settings. I did a 'refresh' about an hour ago. I am not seeing any network activity that I cannot recognize. I d/l'd 'Malwarebytes' and ran it..."no threats". MS Defender has always been on & protecting me. I have never had this situation occur before and am hoping for some help (5 to 10 seconds to wait for what you've keyed in is not fun).

Even though I actually have only 1, 2, or 3 Firefox windows actually open, subsequent browsing is is stacking up instances. Following is a copy of Windows' "processes screen" illustrating an actual instance. At this point, I run out of memory and Firefox crashes.

Three times in the last few months when I was forced to do a TeleDoc visit using my health care provider's 3rd party teleconferencing software I noticed that it changed my Windows 10 sound setting from the correct Optical (Digital Audio S/PDIF) to the incorrect "USB Audio Codex". Consequently, I couldn't hear anything until I changed the sound setting back to Optical. The 3rd time the user interface had changed significantly and for the better except that the sound setting had not only changed to USB Audio Codex, but it was stuck at that setting--so the Doc called me on the phone so I could to listen to what he had to say.

I don't think this is browser dependent. The 3rd time I was using Firefox, the previous 2 I may have been using Edge. I am still very surprised, think that it's a security issue (I'm using Bit Defender), and wonder how else Windows can be tampered with?

Please let me know what you think, and what my next step should be?

A few days ago I tried to download something from a modding website for a game, and the download simply failed instantly. I thought it might have been an issue with that website, but after pressing on with my plans with Edge and later trying to download Microsoft Visual Studio through Firefox, it failed again.

A week or two prior downloads were working fine, and I hadn't changed any Firefox settings between now and then. There's clearly something blocking downloads, but I don't know what. I'm not adept enough at fiddling with individual settings all day to know what they do or figure it out easily. All I know is that pretty much all of the conventional solutions from the most recent posts about this (2+ years ago) are not working. I've tried messing around in about:config and about:profiles, tried disabling and unchecking Firefox security settings, and changing the directory for downloaded files. I've even tried disabling Windows Firewall and Nord VPN.

Version 127.0.2 for linux. Opening a direct link to a pdf file gives the error --- Downloading [file].pdf.part (header) [...].pdf.part could not be saved, because an unknown error occurred. Try saving to a different location. --- The file name is 144 characters long including spaces. I don't have any technical browser experience so I'll put what I know. These are the headers HTTP/1.1 200 OK Server: nginx Date: Fri, 28 Jun 2024 03:52:54 GMT Content-Type: application/octet-stream Content-Length: 4841076 Connection: keep-alive ETag: "65a096a5-49de74" Accept-Ranges: bytes Content-Disposition: attachment; filename="[144 char long filename].pdf" Everything seems okay. When I click on the link instead of opening as Save As, which I think it should, it immediately gives me that error. I have the ask me where to save thing checked. My home directory is ecryptfs. Ecryptfs says it has a max file name of 143 characters. Mine stops working after 140 characters or 144 including ".pdf". Anyways I think the file name breaks my file system. I was trying to download two pdfs. This is another one I tried to download earlier that gave me the error. It's definitely above the characters my file system can handle. https://download.library.lol/main/2860000/6148479dea7d8c9661201ecfc6108525/Alexander%20Brown%20-%20The%20genesis%20of%20the%20United%20States_%20a%20narrative%20of%20the%20movement%20in%20England%2C%201605-1616%2C%20which%20resulted%20in%20the%20plantation%20of%20North%20America%20by%20Englishmen%2C%20disclosing%20the%20contest%20between%20E.pdf It's public domain from the 1800s. I don't pirate. I was able to download it with wget while choosing a shorter filename. I don't know why it wouldn't let me choose after clicking the link. [solved] I have a few more problems I'd like to put in this ticket. A. After giving me the error Firefox crashed immediately afterwards. This was a few days ago. Firefox has never crashed like that before in months. I don't remember exactly what happened but it did crash. If crash logs are needed I can find it. B. After attempting to downloading a video (mp4) file this happened. The mp4 file didn't show up anywhere but a -1 byte part file showed up. It took the name of a subfolder in the folder I had intended to download the image file. I'll explain it in further detail below. I attempted to download an image in /home/user/Documents. In the Documents folder I had another folder which I'll call example. So /Documents/example. I did save the video in Documents but I don't think that mattered. After closing the save as box that popped up after clicking save video I noticed the weird file show up in the Downloads tab. It showed up in the "example" folder and took the name "example".part. Remember I never chose the "example" folder but I did choose the Documents folder. All my files inside the "example" folder broke and I couldn't delete the weird part file. Clicking properties showed the permissions could not be determined. When I interacted with it (I think I tried deleting it) it gave me an error with "gvfsd-admin daemon". I don't remember what it said exactly. I applied my folder's permissions to its contents and I was able to delete it. It doesn't show up in my downloads manager now. I ran clamav and everything was fine. Note I downloaded the video from a trusted source, twimg or the twitter video host. That's all. I'm almost certain it's due to the filename length. Cancel that. I didn't realize the "Applications" thing did that. I'd suggest to override the "Applications" preference if an error saving occurs. I'd still like to ask about A and B though.
