System Info: 1. Windows 10 Home 22H2 (as of writing) 2. Firefox 118.0.2 (as of writing)

I'm trying to make the simple change of moving the location of the 'find in page' bar from the bottom to the top and I recently discovered that using userChrome.css was the way to do it. I followed this tutorial in the following link, https://www.userchrome.org/how-create-userchrome-css.html, making sure to put the "chrome" folder in the right location C:\Users\myName\AppData\Roaming\Mozilla\Firefox\Profiles\sfytm5xk.default-release, switching the toolkit.legacyUserProfileCustomizations.stylesheets to true, entering the code snippet into the userChrome.css using VSCode, and restarting the browser for the changes to take effect.

After the first restart, I found that the 'find in page' bar was still at the bottom and nothing had changed. I restarted the browser about 10 more times and nothing changed still. I looked through the Mozilla Support forums, r/FirefoxCSS and r/Firefox subreddits for an answer and came across a few posts with similar problems, tried their recommended solutions such as downloading the userChrome.css file from the website tutorial, double-checking that File Explorer would show file extensions when creating or renaming files, or even restarting my computer and yet none have worked.

I have no idea what's wrong so feel free to share what you think the problem might be and possible solutions in the replies.

Every time I open Firefox after closing it, I get the message below. I can click the button to restore session and it works every time. With each update, I hope to never see this message again, but after installing a new version on Ubuntu today, I see the same familiar message. This is not linked to a computer, or an operating system because I've seen this on both Ubuntu and Mac. If Firefox could literally just click the button that would be awesome.

Sorry. We’re having trouble getting your pages back.

We are having trouble restoring your last browsing session. Select Restore Session to try again.

I am trying to access websites that use three.js. When I initially start, the website runs too slowly to be usable, but if I tab out for some time and then tab back in, the website runs at normal speed for a bit before slowing down again. I cannot find any solutions to this problem nor anyone else who had the same problem as me.

OS: Windows 11 Home 23H2 (22635.3720) Firefox Version: 126.0.1 GPU: GIGABYTE NVIDIA RTX 4060 Ti 8GB GPU Drivers: Game Ready 555.99

In English, the meaning of this error is: Title: Configuration error Content: Failed to read configuration file. Please contact your system administrator.

I had this error for a long time. But it's not too serious. Just hit ok and I can use all the recovery tabs as before without any problems. But every time I open windows and open the browser, this message appears. I feel very uncomfortable and tired without knowing why. Even reinstalling the browser didn't fix the problem, I tried it before and lost my favorite browser theme. And 1 more thing if someone can explain. If it can't read the configuration file, how can I still use the browser? What does that configuration file do?

This message only appears when I have not opened the Firefox browser on my computer. If I already have the tab, I can open another firefox browser without that message appearing. Only when I close all tabs. Open it again and it will appear. And click ok to use normally.

Hi, it has been a while that one of the updates on firefox removed the ability to navigate using the middle click, i waited and waited for some day an update drop and fix that but it's been a while and nothing has come, i was sure to test this on another computer and it didn't worked as well so i'm pretty sure firefox has some problems, i mainly use a drawing tablet because i don't have a mouse, so navigating is a bit hard without the usual middle click nagivation(i'm not sure if there is an actual name to that), please help

What am I supposed to do about this new problem?

"XUL Runner This profile was last used with a newer version of this application. Please create a new profile." I did create a new profile. I have like 4 different profiles now from every time I've had to reinstall Firefox because it keeps crashing and freezing.

Access to Google sites (Gmail, Google Search, Google Calendar) with Firefox (v. 100.0, 64-bit) is very irregular. I can sometimes open the pages, but can't, e.g., edit calendar entries. Often when I click a bookmark (in the Bookmarks Bar), or enter the URL for a Google site, nothing happens. Clicking other bookmarks opens the corresponding pages. Only Google sites seem to be affected. Is FF blocking Google?

A couple users at our site intermittently receive a SSL_ERROR_BAD_MAC_ALERT error when navigating to Google in Firefox. This happens in Version 99.0.1 (64-bit) on Windows 10 computers. When the issue occurs, users can navigate to other websites without issues. Navigating to Google in a different browser works no problem. Restarting the browser will resolve the issue. Clearing cookies and site data has no effect. Users can also refresh the page after some time and the issue will go away.

Any idea as to why this is happening?

My work consists mainly of capturing accounting data online. It is important that the browser warns me if I try to close or navigate away from a page if the data entered has not been saved or updated, but I no longer get these warnings.

Please help.

I had the same problem like the link below when I use firefox.

https://www.reddit.com/r/firefox/comments/tjxh7s/videos_freeze_when_window_isnt_in_focus/

So, did what the instruction says and it solved the problem regarding discord.

But, since I changed that setting, firefox doesn't remember my google login or dark skin settings of other websites (it was always automatically logged in when I use YouTube. Not like it remembers the password).

How can I solve it? I resetted firefox multiple times.

Firefox just turns into a black screen and becomes unusable. It has been happening for a long time now and i have checked RAM and CPU usage and they are all fine, as I explored potential causes.

I will be using firefox and it just turns all black on all screens and is completely unusable. To use it again I have to force close all windows and reopen it and it works again.

This is a frequent issue that I have seen

Hi, I'm having this problem of videos not playing in some websites for a long time now, not even sure how long anymore. It started on Twitter, where I get the error message "The media could not be played". Some time after I got it on Instagram where I get the message "Sorry, we're having trouble with playing this video. Learn More". More recently I subscribed to the Nebula service and got a message there as well "The media could not be loaded". Differently from other people I don't have this problem on Youtube, over there everything has always been fine. I have tried every workaround on this, I have seen many tutorial videos and articles and tried everything and nothing worked. Running on Windows 10

Some things I have tried: -cleared cookies and cache; -disabled all add-ons, removed them even; -checked if firefox was updated; -checked if graphics card drives were updated; -opened websites on incognito mode, nothing changed there; -started Firefox in troubleshoot mode, nothing changed there; -disabled graphics hardware acceleration in Firefox; -enabled autoplay; -reset firefox; -changed my pc actually, installed firefox, got the error and reset firefox again;

Could anyone help me with this? Is this normal?

Hiya. I usually have a fairly large number of tabs open on the browser. I use the Panorama View add-on for tab management. Usually this means that on any given container I have about 10-20 tabs open for a total of some 300 odd tabs. The nice thing is that Firefox doesn't usually load all my tabs so this works out for me. Recently however something weird's been going on and Firefox just refreshed ALL my tabs across all the containers. This kills my performance completely, especially given a fair number of tabs are just random youtube links. When all my tabs are open Firefox eats up like 25 GB of RAM, which is understandably not great.

I tried refreshing Firefox to no avail. Is there any way to stop this constant loading of all tabs?

After updating firefox to 112 it now starts with ugly white ui dummy before actually loading proper UI. Screenshot attached. It was not happening on firefox 111.0.1. It happens every time I launch firefox 112. Of course nothing in changelog is said about changing performance or UI so I have no idea what is causing this.

All typed text appears blue until you break it in some ways like pressing the spacebar or moving the keyboard cursor with the arrow keys. It happens at the firefox search bar as well, and search suggestions and autocomplete doesn't work whenever it happens.

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.

Hello. I un-installed Microsoft Edge and Office 365 and now Firefox has stopped working (on another computer not this one).

This is the same problem that someone reported in 2021, but that thread has been archived.

https://support.mozilla.org/bm/questions/1356550

The advice then was to re-install Firefox and to download Visual C++ \ Visual Studio files ( especially VCRuntime1401.dll).

My problem is that I don't have a browser on that computer, I am completely cut off from the internet and can't download anything.

Is it possible to download the necessary files on this computer and transfer them to the one that has the problem? Thanks.

Is there any way to make Firefox show the "back", "forward", "reload", "bookmark" buttons that are shown in the default context menu when right clicking a web page also in the context menu that is shown when right clicking an image?

I think those buttons should always be included in all context menus opened for a web page, no matter if you happen to click on the background, on selected text, on an image or a link because.

It is so frustrating having to open the context menu multiple times to find a location where the default context menu is opened instead of the specific ones for selected texts, images, links etc.

Thanks!

One website in particular is almost 100% black. I cannot see most text. On another site, I cannot see check boxes, can't see the trash can icon.

This just happened recently. When I switch to Light Mode in the settings, both sites remain dark.

What settings can I change so everything on a site is visible?
