Hi, I have been searching a way to change the Firefox new tab background image keeping its vanilla design. I found I could use a userContent.css file in this post from a few years ago: [https://support.mozilla.org/en-US/que.../1271362] I have followed the instructions step by step but it doesn't currently work.

As shown in the image the tags field is missing from my bookmarks editor. Any idea how this could happen? Any options or about:config options I should check?

I've attached troubleshooting information. I'm on Arch Linux and I have two other Arch machines on the same Firefox version (Arch Linux Package) that do not exhibit this behavior.

I use Firefox on a PC to access Facebook (website, not app). This week the Messenger/Chat feature stopped working. I click the icon and it opens but nothing appears in the box, it just hangs. There is an option to open in its own window, but that also is blank - no past messages, no contact names, no ability to start new message. When I log onto Facebook in Edge, Messenger works fine in Facebook.

I've tried everything I found on the internet for this issue - updated and refreshed Firefox, cleared history/cache/cookies/site data, uninstalled and reinstalled Messenger, refreshed Facebook to initial settings, used Firefox in troubleshooting mode, reset everything, turned off browser, turned off my computer, used shift key to reload tab - nothing has worked. There are some instructions about stuck cookies, but I didn't understand them so I didn't try that one thing. I've gone into every menu I can find to try to figure out this issue, which isn't the end of the world, but I would appreciate some other ideas for what is suddenly causing this. Because now I have to redo all of my settings and preferences and logins and the problem still isn't fixed.

I have a list of clickable bookmarks that normally displays in the left side panel. It's currently missing. If I click on 'Other bookmarks' it appears to the right but is not pinned and doesn't seem pinnable. How do I get it back to displaying in the left side panel all the time as before? Clicking on 'Bookmarks Toolbar' or 'Bookmarks Menu' doesn't bring it up. I don't see any other options in the side panel nor do I see anything relevant under 'Bookmarks' in the top ribbon menu......? Many thanks and regards Ray

What is the solution to the following problem? PR_END_OF_FILE_ERROR

This issue has been reported many times. It has been occurring quite frequently, to the point where I've had to abandon Firefox and use a different browser.

Hi,

I am a regular user of the Android version but currently when I get my search results it freezes and when it doesn't none of the links are clickable. Other browsers have no issues, anything I can do?

When i go to google.com and enter search query the tab "hangs" for about 10 seconds before the next page starts to load Same issue on 2 separate machines (1 intel laptop, 1 amd pc) both on newly installed windows 11 pro

what i've tried: safe mode, disabling hardware acceleration, disabling antivirus (kaspersky, without any browser plugins or safe browsing) , but the issue persists

Hi, how do I enable notification web sites pop-up message from the corner of my windows taskbar ie; from my screenshot? I want to switch 100% away from Chrome but this one feature I can't figure out how to enable from web sites like Twitter/youtube/reddit/etc...

Thank you.

I got a notice that Firefox (and Thunderbird) were updated this morning. Took me an HOUR to find out how to make the miniscule font in my inbox larger. So.. suddenly, new problem.

When I click the Firefox icon to launch the browser, and reopen my tabs, It opens for a millisecond, then closes faster than I can try to read if there is an error. When I click it AGAIN, all my tabs are GONE and I have to search for them manually, which is a royal pain.

Why is this happening? How can I stop it from happening? This is annoying as hell.

I am on Android Firefox and I accidentally chose "Always" on the pop-up asking where I want my downloaded items to go. I want to change it because where the files are now sent is inconvenient at best but i cannot find such an option to change my preference in either the Firefox settings bar nor my phone's device settings.

I'm having a problem with Win 11 that will likely require that I reinstall the OS. I decided to move most of the data in my User folder by right clicking and changing the drive from "C:" to "E:" in the Locations tab. Firefox was closed as a I did this, it worked fine, and then I restarted the PC. Upon opening Firefox none of the extensions are working and I'm not sure what to do.

I don't know why, but since today firefox keeps reloading all my tabs I have open every couple of minutes. It happens on both my desktop and laptop and its getting annoying. I also disabled the auto refresh in config, along with clearing the cache. I uninstall the plugins that I installed last week, and still happens.

About a week ago my phone (Sony Xperia ZX2 Premium running Android 10) started 'crashing to the lock screen' whenever a download finished in the mobile version of Firefox. If multiple files are downloaded in short succession a popup will appear informing me that the 'System UI keeps stopping', with a prompt to close the app or to get to the app info (see the attached photo - clicking either option sends me back to the lockscreen, with the only difference being that after unlocking the phone the former will have stayed with Firefox in focus, and the latter having opened the Settings app on the System UI entry).

Going to about:crashes shows no recent crashes on Firefox's ends. (Plus, Firefox shows no signs of having been closed [like tabs being reloaded] after unlocking the phone again post-crash). The issue currently only happens when downloading a file through Firefox; downloading a file through Edge, Discord, or the Google Drive app produces no problems.

I have already tried force-stopping and restarting Firefox, restarting the phone, and clearing the download history with no luck. Furthermore, I have also checked for updates for the system, the Google Play Store, and Firefox for Android, however all of them were already up to date.

Any help would be sincerely appreciated.

Can I get an explanation for what this does

Is it supposed to do something different than the windows taskbar mouse thumbnail

I saw no difference when enabled.

Hello, Please help me to resolv the error: The media playback was aborted due to a corruption problem or because the media used features your browser did not support."

When I try to sign into any Google product (Drive, Docs, Classroom, etc) in Firefox on my Android phone, it brings me directly to a "sign in with Microsoft" screen. I think this is because my old Microsoft account is the default account for Google products, but it is now deactivated so I can't sign in from there. I can't get out of that page, though, so I can't sign into any of my Google accounts at all through Firefox on my phone.

I'm trying to connect to my Schneider XWPro Gateway for access to my solar inverter, and security policy on Firefox no longer't allows access. I can access using Safari by explicitly allowing access. Error from Firefox is as follows:

Secure Connection Failed

An error occurred during a connection to 192.168.1.120. You are attempting to import a cert with the same issuer/serial as an existing cert, but that is not the same cert.

Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem

Your error message states there is a problem with a certificate conflict, however there is no apparent way to tell which certificate is causing the conflict, so there is nothing I can do about it. This is a new problem, I have been able to access this device in the past.

Any suggestions?

In windows 10, I got used to opening a new window in FF and then a "tab" for the new window would open in the taskbar. I could then switch between windows by clicking on these tabs on the taskbar. In windows 11, I can click on the FF icon in the taskbar and open a new window, but a tab for that new window no longer appears on the taskbar. Instead of the previous tabs on the taskbar for each new/open window, there is nothing. I have tried the suggestion, found in another thread, to use about:config to change to false the setting browser.taskbar.previews.enable, but there was no difference. Does someone know another approach, or is this a windows 11 "feature"?

I occasionally use a site (www.zoomcare.com) which does not work properly with Firefox (I've been using Microsoft Edge (Windows 10) to access it). The problem comes when I try to login. I enter my username and password, and that brings up a blank page that does not redirect to anything, so I'm stuck.

Just out of curiousity, I was looking through Advanced Settings, and found security.csp.enableNavigateTo. It has been set to false, but when I set it to true, I am able to successfully login (I still go to the blank page, but after a brief pause, I'm redirected to a logged-in page).

I'd like to know something about the security implications of enabling this property. Is it a bad idea? (Not knowing, I've set it back to false and will continue to use Edge for now).
