Hi there!

I'm trying to troubleshoot why firefox isn't connecting to my DNS over HTTPS instance running adguard home. Every other device (including another laptop) is able to set the DNS over HTTPS and connect successfully - but my desktop PC instance gets NS_ERROR_CONNECTION_REFUSED. Despite multiple reboots, ipconfig /flushdns, release/renew, etc...

Even my android phone is able to connect to it using the "private dns" feature (uses port 853 instead of 443).

I've been able to verify https access to the DNS server and it's querying successfully. It's just this one instance it won't connect.

Hi All,

For some reason my tab icons look a little low, and I would like them more vertically centered.

I've been trying to move these icons around using some older code that doesn't seem to work anymore.

The code below no longer has any effect.

Does anyone know how to move the tab icons up 1 pixel?

Thanks!

/* padding doesn't move them */
.tab-throbber, .tab-icon-image { padding-bottom: 4px !important; }

/* margin doesn't move them */
.tab-throbber, .tab-icon-image { margin-bottom: -2px !important; }

/* can't even turn the icons off LOL */
.tab-icon-image { display:none !important; }

A bit desperate here. Windows crashed with no chance of repairing the installation. Hard drive And all files on it are accessible. Firefox had thousands of bookmarks for a very important project.

There seems to be no Firefox profile on the drive. Searched in hidden folders as well. Certainly not where it’s supposed to be: …\AppData\Roaming\Mozilla\Firefox\Profiles

Search for all files on the drive, but there seems to be no SQLITE or JSON files related to Firefox.

Not even a folder anywhere in the drive called Mozilla or Firefox or Profiles or Profile (at least not in relation to Firefox).

There’s no file called places.sqlite or bookmarkbackups anywhere on the drive.

The drive itself seems to be in a good condition and all other files are there and accessible. The file system doesn’t seem to be corrupt And man thousands of bookmarks were there before windows crashed.

Also checked places in \Roaming\ Just in case, as sometimes it could be found there for some installations.

Nothing found anywhere so far. Seems like running out of options.

Any ideas would be greatly appreciated.

Thank you very much everybody for your time and attention.

Hi,

I recently facing an issue that the Firefox browser randomly maxed out my RAM and went unresponsive. Like the screenshot below, I am only trying to open Facebook and Instagram, 2 tabs.

I have tried to open about:memory and about:processes to monitor but it just went unresponsive and both the monitoring just hanged.

Have no idea why the Firefox process taking up so much RAM. Need help.

I've followed all the recommendations. Problem still happens in troubleshooting mode as well. Doesn't allow sign in either. Have reloaded all C++, uninstalled, reinstalled, restarted. No links or pages will open.

I was able to open reddit.com without any problems earlier, but recentrly I'm not able to load it up anymore. The loading screen is eternal and it doesnt show any kind of error (unless it tries to connect for too long like a couple of minutes, then the error does shows up). The site still sends me notificarions through the browser though. Any other site loads up without a problem. I tried to use methods mentioned in the help article (turned off proxy, turned on network.dns.disableIPv6, deleted cookies and cache). In other browsers (Edge, for example) reddit.com loads just fine. Please help me if you can.

Hi,

This has been brought up before, but not with this exact question (not that I could find, at least).

I understand that cookies cannot be synced across devices, but this is not what I am asking for. Is there a way to make firefox sync the list of exceptions? Meaning, only the specified website URL and its status, not the cookies from these sites.

I have about 30 bookmarks on Firefox I use all of them on a daily basis. When I opened my Mac today, it had different wallpaper on the screen. I could not find Firefox on my dashboard at all. I had to pull it from my launchpad app. Please help my... I'm desperate !! Kenneth Mee (medic1464@aol.com)

This isn't the first time this has happened. After each occurrence, I have to completely uninstall the browser and reinstall it from scratch. This means I have to reopen all my tabs, which is very annoying. In Chrome, I have had a large number of tabs open for many years and it works fine.

With Mozilla, something terrible is happening... I have many tabs open in Mozilla, and there comes a moment when, upon launching the browser and opening two or three tabs, Mozilla starts consuming up to 10 gigabytes of RAM. If I open a few more tabs, the browser crashes. I don't need to open 50 or 100 tabs, just 7-8-10 tabs are enough to make the browser crash. Moreover, if I open a new tab and go to google.com, the browser takes a very long time to load, even if it's the second tab.

This problem has happened before. I don't do anything with the browser, just visit sites like YouTube.

Clearing the cache and other recommended actions do not yield positive results. This is very annoying. Mozilla is my first and favorite browser, which I have been using for almost 20 years. I wouldn't want to uninstall Mozilla.

Firefox crashes whenever I use ctrl v or right click, and pulls up a window that it crashed. Whenever I start it back up, it says it wasn't able to restore session, then restores it anyway after I press to restore it. Another thing is whenever I try and upload a file onto a site it crashes as well. I'm on Mac OS x 13 and reinstalling firefox hasn't fixed it. This is relatively sudden, it happened about around 3 days ago for the first time, and at the same time I noticed it happening certain sites also started giving me '502 Bad Gateway' errors. Does anyone know what's happening and how to fix it? Thanks in advance!

Windows 10. Weird glitch.

If I use Wondershare UniConverter's downloader function to download a video, as soon as the download starts, all Firefox open windows close. This is a recent thing, the last couple of weeks or so. I have reinstalled Firefox and UniConverter. The first time I tried it after reinstalling UniConverter, all was well. But the same issue has shown up again. I have tried rebooting my PC to no effect.

Any bright ideas welcome!

I am migrating to a new laptop. The new laptop keeps asking me for a primary password. I have never set one up. This issue doesn't happen on the old machine, only the new one. It also won't let me disable the pop-up that asks for the primary password. Please advise.

Automatically hide taskbar in desktop mode => Enabled Firefox => Maximised When cursor is moved to outer edge of screen, taskbar should unhide (Expected behaviour) but in this case it remain hidden (Reality). Firefox along with all other spinoffs give same result. Chromium based browser works perfect, and taskbar automatically unhide itself.

As OLED screen have became common as monitor, Taskbar auto-hide is must. If this issue cann't be fixed I may have to change my primary browser which I used for almost 15 years.

Kindly, look into it. If Chromium can do it, why not Firefox.

Always shows "Failed to check for updates" On version 125.0.3 and still says needs to be updated. Then just run the install again and then it stops for a bit still on same version and then shows up needing update...been doing the same thing for a while now.

I often have many tabs open (25+) I have made it so tab shrink way more then normal (I like the way chrome handles tabs where they basically just shrink infinitely. Firefox doesn't do it's even with my twerks but ohwell.)

so when i want to click on a tab with audio playing at a small size i often mute the tab instead of clicking on the tab

Where and how can i remove the mute button that appears when hovering over tabs with audio playing?

I have never found that mute button useful so removing it will not impact me

Before the update on April 29 I had no issues with my eBay account on Firefox. Now I am unable to get the pages to work properly. I cannot list any items for sale nor can I change any of my items in my store. Nothing saves and then redirects me to the homepage. eBay is one of my trusted seitz so I have no idea what’s causing this. It’s not eBay because my other accounts work fine on Chrome and on Safari. It happened exactly when the last update happened. And the only way that I can actually get back to the original site is to clear all my cookies and log out and start all over again, only to have the same issues over and over. I don’t know who to contact. I’m losing money in my Business every day because of this so I’m going to have to change my browser unfortunately if I don’t get a solution as soon as possible. Thanks for anyone who can help appreciate it.

Hi,

I was using FF on Ubuntu 22.04.4 LTS. Had version FF 120.x and playing video in Netflix worked fine. Then I updated to FF 124.x and playing video stopped with error F7355-1203.

I've checked the DRM setting and it is enabled, I checked addons and I have OpenH264 and Widevine installed, both set to always active.

I've checked installed codecs and I do have libavcodec58 installed. No update for that available via apt. I also have ffmpeg installed, no problem with that either. I can play Netflix videos in Chrome, but not in Firefox now. Something happened to Firefox when I updated from 120.x to 124.x. Today I updated to 125.x, same problem, Netflix video won't play.

I've unchecked the DRM setting and re-checked it, and that does reinstalled Widevine but does not fix the problem.

Any ideas what could be the cause?
