I use CCleaner>Options>Cookies to save cookies in certain containers. I see that Firefox uses userContextId to specify a container. Where can I find which userContextId NUMBER is assigned to which container NAME?

When watching videos on YouTube or Amazon Prime, Firefox will eventually stop recognizing keyboard and mouse input in all windows and tabs. This can happen after just a few minutes of video or after hours. It affects nearly all input: typing or clicking in webpages, the toolbar, the address bar, etc., though I can click the 'x' button to close tabs. When I close the final window, a dialogue will appear stating that Firefox is non-responsive and allowing me to kill the process. This seems unusual, because the OS's system monitor indicates there is plenty of unused and available RAM and CPU resources. Firefox behaves normally after restarting.

OS: Xubuntu 22.04 Firefox version: 120.0 (though previous versions have been affected for the last few months)

After the most recent update, Firefox often takes 30 seconds or longer to load pages. This behavior began yesterday and has continued today. This isn't the first time this has happened. Solutions?

As of 21/11/2023, I can no longer use several chat services that had previously worked on Firefox, for example Santander bank and EDF. Plus, the POWR widget has stopped working on one of my favourite websites.... it used to pull in the charity's Facebook content but now all I see is the text and no imagery. All of these functionalities work fine in Google Chrome and Edge so what's wrong please? Thanks in advance UF https://www.aldingbournetrust.org/make.html

Updated FF Tuesday evening and noticed first on Wednesday when unable to log in to my Tesco food website. Access not allowed from this server or some such. I tried to use the Tesco feedback form and then got alerts both from Avast (saying it was infected) followed by FF refusal to connect. I tried safe mode and removing and adding FF.exe to Avast without change. I reset FF without change. MS Edge allowed access to all these sites without a murmur.

Today i can get to Tesco main site but still not Feedback.

Also my local Synolgy NAS now has a warning that it is dangerous to access from FF. Nothing has been changed in its set up or security. I can and do override and access everything

Something in the Tuesday update has caused this clash. I did think at one point I also saw 120.0.1 being offered but that may have been my confusion.

Happy user of FF fro many years and do not want to change.

Trying to access my Tesco account but a page saying 'Access Denied on this server' appears. Can you rectify this? I urgently need to login to my Tesco Account.

PS. I have tried to solve the problem for 2 days but no success!

Since yesterday I can't access multiple websites like Spotify, Reddit, Google Drive etc on my desktop computer anymore. I don't know why and I didn't change anything over night. It also works fine in Microsoft Edge.

Reddit shows the "whoa there, pardner" error, spotify shows 403 error, Google Drive says my browser (Firefox 120.0) isn't supported and others are simply unavailable. At the same time Google looks off and Twitch is just a huge loading screen.

I cleared all the data (cookies/cache), but that didn't help.

I had this reddit error a few weeks ago already, but it disappeared on its own. However it was only reddit that was affected.

If I right click a folder of bookmarks and select "Open All Bookmarks", the focused tab switches to the first bookmark in that folder, despite the fact that I do not have the following General preference item: "When you open a link, image or media in a new tab, switch to it immediately". While that item doesn't specifically describe the "Open All Bookmarks" situation, it's kind of the same idea. I have groups of bookmarks that I often visit, and I don't my focused tab switched every time request one.

I am trying to login in to my health insurance website but Firefox keeps giving me a message that it can not access the information at this time. This is not the first time or the first website that I have had issues with. Do i have to switch to Chrome or Edge?? Is there a setting that will allow me to access the insurance website?? I have used Firefox for years but the past few months it has caused me lots of problems trying to access my accounts on various websites.

I get this message when trying to access this site: "We can’t connect to the server at www2.optumrx.com"

I can then go to another browser, like Edge and I have no problem accessing the site. I am using a Windows 11 Lenovo computer running Firefox 120. This problem just started to occur.

Moderators, I am copy and pasting the below warning I have seen on similar posts at the top of the post.

--- WARNING: This script is not provided by Mozilla and is not officially supported Creating a userChrome.css file and other ways of customizing Firefox that are not exposed in the interface are there for developers, not end-users. If it were intended for end-users, you would see a menu option or checkbox; you wouldn't have to hack a text file in a hidden location.

What this means is that even though the functionality you want is no longer supported, a third-party has found a way to do it using the CSS file. If it breaks in new versions, you will need to contact the person who provided the script.

[Warning was not added by moderator, but by me to save someone time.] ---

With that out of the way, here's the issue I have, how I've solved it temporarily for the community.

When I load YouTube videos, I am given a statuspanel message with the URL of the video playing. It's not momentary or temporary, it stays there, the entire time. Why anyone thought this was a good idea, I'm not sure.

My question is simple, is there an alternative solution - to remove this statuspanel message permentantly - to what I'm sharing here, without using the userChrome.css file?

If so, please provide the solution so it can be tested and upvoted by the community, thank you in advance if that is you.

If there is not, then this post also serves as solution as well as a request to Modzila, that being.

Modzilla. Please make a solution that doesn't need custom .css scripts.

I am posting this as I needed multiple posts to achieve a solution so am hoping this serves as that for someone (including myself) until Firefox resolves this issue themselves, another way.

Solution: Windows 7/8/10/11 as of Firefox version 120.0

1. Go to about:config, click Accept the Risk and Continue 2. Type "toolkit.legacyUserProfileCustomizations.stylesheets", toggle this to true 3. Close all instances of Firefox 4. Open Explorer, navigate to %appdata% then navigate down to \Mozilla\Firefox\Profiles and select your profile folder. If you only have 1 it may be obvious, if not for me it's the only "~.default-release" folder, where ~ is a random set or letters and numbers. If you're unsure, pick the first folder named like this, then repeat the next steps for all profile folders, or use trial and error if you prefer until you achieve the desired result. 5. Make a new folder "chrome" in that folder. 6. In this folder make a new .css file, right click make a new .txt file rename the file and extension "userChrome.css". 6. Open the blank .css file with a text editor and paste this line without quotes "#statuspanel {display:none!important;}" and save. 7. Attempt to load videos or pages where messages usually appear in the bottom left and observe the results

There are various other posts both here and other places that I have combined to write this solution, none of the others worked on their own, for me, which is why I write this and to refresh the request to the Modzilla Firefox team, to please, share or make a solution so we don't have to do this, as you'll otherwise need to continue supporting this legacy feature in future versions of Firefox.

Note: This will likely remove all statuspanel messages on other pages too, I have read other statuspanel commands online so if you want to be particular about muting some and not others, you may need to modify the file further.

Yesterday Firefox started closing at random, sometimes instantly as soon as I open it. The crash dialog doesn't open, and if I go to about:crashes my most recent unreported crash is from 2019. Tried refreshing, reinstalling, completely wiping all profiles and starting fresh. If I use troubleshooting mode it won't open properly at all. I am at a bit of a loss, any ideas?

Since yesterday any streaming services such as Netflix or Hulu will only have green screen for the video. The sound will come through just fine and subtitles. My Wildvine is updated, I've toggled the DRM on and off several times, no changes. My browser has been checked for updates. Not sure what else to try at this point.

Firefox crashed and I couldn't get it restarted. I had to uninstall it and reinstall it. I lost all of my bookmarks, logins and other information. What do I do to recover it?

Unless I'm crazy, Firefox used to import the tags in an exported bookmarks HTML file. I used this to move bookmarks between profiles. What happened to that capability?

I've set custom fonts through Settings > Fonts > Advanced, but the fonts I have specified are not being used on any websites even if I uncheck the box that says "Allow pages to choose their own fonts, instead of your selections above". For example, I've set the default sans serif to Source Sans 3, but websites use Arial regardless of the settings. The only custom font I've gotten to work is Segoe UI (the UI font on Windows); all other just fall back to Arial. The problem persists even if I disable all extensions/add-ons. I'm also experiencing the problem for non-Latin scripts; I've tried to set the default Bengali font to Noto Sans Bengali, but websites are using Vrinda instead.

I'm running Firefox version 120.0 on Windows 11, any help is greatly appreciated!
