Firefox Support Forum

I am using an older MacBook Pro running Mojave 10.14.6, for which the latest Firefox is 115.12.0ser (64-bit). It has always been working like a champ, but a few weeks ago, individual YouTube video pages look very odd. Usually the related recommended videos are along the right edge in one row, and below the default video window is the title, description, and then the comments.

The problem I have is that these two components became transposed, and if the video is displayed as full screen, the page can be pushed upwards to show the title etc got squashed below the video window, with the recommended videos still in a grid below it. I hope the included pictures are sufficient to illustrate the issue.

Another computer, an iMac running El Capitan 10.11.6, and Firefox 78.15.0ser owned by a family member, does not show this odd phenomenon. I must say I am quite intrigued by this, and would greatly appreciate any help my fellow members can offer.

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

For about the last 5 days I am not able to use Google Search on my MacBook Air using Firefox. My start page is Earthlink. I keep getting this error message ( Application error ; a client side-exception has. occurred ( see the browser console for more information ). My email is west47916@earthlink.net. Could the problem be Earthlink or Firefox.

I add 2FA whenever possible. I was adding a new website yesterday and was unable to: FireFox (v. 127.0.2 on 64-bit Windows 10) was showing "Log in with Facebook" that was blocking one of the squares on the QR code! So I had to enter the many characters that were presented in order to add the 2FA code to Authy!

I looked in the settings and couldn't find anyway to turn that off.

How can this be fixed?

Thanks,

John

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! :)

Hi,

Thanks for your help with this. When I search for something in FF and click on the MAPS button, it comes up with Apple Maps by default. I would like that button to open Google Maps by default. (Mainly because Apple Maps misses a lot of information and significantly hinders my searches. Invariably, opening Google maps gets me to my answer or information much quicker.

I have tried various help suggestions but simply have not been able to do this.

Please can you tell me if it's possible to do this and if so, how?

Thanks again.

I've been out of town. After returning home Firefox updated to 127.0.2 but now it will not close its process when I close its window. When I try to launch Firefox again I get the error message below and attached:

"Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window. <Close Firefox> <Cancel>"

When I select "Close Firefox" the new Firefox window will then launch. However, if I open any web page the same error occurs after closing the window.

If I launch Firefox and then close it without opening a web page I do not get the error the next time I launch. Somehow going to any web page in Firefox prevents that instance of Firefox from closing.

I'm running Windows 10 22H2 Build 19045.4529 and it's shown as up-to-date.

This started a week or two ago intermittantly on some websites. Today I cannot see any images of amazon items in the shopping cart. I can see the thumbnails in the right side bar, and if I click on an item, the image appears on its for sale page. Ebay usually shows the first image, but the rest won't load, unless I click on "unable to load images" and then they might. Or if I use the icon to put the images in their own box, I can < and > to navigate them

Turned the new "secure DNS" feature off & on, no difference. Turned off NoScript, no difference.

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.

First, I fully realize that my OS is prehistoric - beyond ancient. I simply cannot afford to upgrade right now - I'm working on it, though. So, since the last update on ESR, everything seems to be working well, browser-wise, except for a sudden change when using FB. They're problematic, so I thought it was something there, but there are no problems with any of my other devices ( 2 phones & an ipad). For most situations on FB, without going into the whys, I need to use my/a laptop, instead of anything else. It has begun freezing and lagging -sometimes, for 10 minutes - after I start typing! And, the emoji panel takes that long to appear, then longer after hitting one! It's basically unusable. I already contacted them, and as previously mentioned, the laptop is the only problem after the last update, the other devices work well, in terms of speed. I'm wondering if there's anything I can do here to remedy this. I have 9 billion bookmarks and my settings are set in stone, so I can't risk losing any of that by reinstalling, or anything like that. I've been with Firefox since it became available, many years ago, so I'm not willing to sacrifice anything I've collected. All was fine, until this last update. And, I'm working on getting another laptop. Thank you for your time.
