Firefox supportforum

I can hear NO AUDIO on ANY webpage, when in Firefox. I have gone through all the suggestions on this page: [https://support.mozilla.org/en-US/kb/what-to-do-if-firefox-wont-play-any-...] but still have the problem.

Ever since Firefox browser updated, my Home (specifically Shortcuts) has been glitching.

They do not show up, no matter how many rows I add or subtract. Web search and Recent activity still works (to an extent) but Shortcuts? Never again. Please fix it ASAP.

Samsung Galaxy S24 Ultra running latest Android update and latest Firefox update. I set Firefox as my default browser. I have un-installed all updates for Samsung Internet and removed all permissions for it. Disabling it is greyed out. Some apps that I use have links to websites. Too frequently, when I go to one of those links, the intro screen for Samsung Internet opens. Then, when I look at the settings in Firefox it is no longer set as the default. Then I set Firefox to default and go to my phone settings to see that Firefox is selected as the default. If I open the previously mentioned app and choose the web link, Firefox will open. But somewhere along the way, the default changes back to Samsung Internet and it's a vicious circle. I have posted in a Samsung forum but haven't gotten a reply that solved the problem. Please help. Thanks Mike

When accessing my site (in attachment to avoid indexing), Firefox blocks with a "Possible security risk" interstitial. DoH requests to the configured https://dns.google/dns-query service work from an external application on the same machine as the browser, but about:networking#dnslookuptool reports the host being unknown.

Hello! I updated FLOORP on the 5th May, FLOORP crashed and then Brave, Firefox, Waterfox, LibreWolf and Vivaldi started crashing. I had Brave and Vivaldi open when I launched FLOORP and FLOORP asked consent to update itself and after updating, it did not open in “previous session” and I could not open “previous session” through History. When I launched “Settings” from menu, “previous session” opened! I had pinned “Settings” earlier.

Now the bizarre happens; suddenly LibreWolf launches by itself also without “previous session” and open tabs in Brave and Vivaldi disappear to single New Tab. After some tinkering, I was able to restore “previous session” in LibreWolf, Brave and Vivaldi.

Now I close all browsers and open Firefox, no “previous session” and some random windows in its history, opening these random windows also opened “previous session”! 🙄But then Waterfox launches also without “previous session”, here clicking on OneTab extension recovered “previous session”.

Cutting short; I uninstalled, Waterfox, LibreWolf and FLOORP, this did not help, I ran System Restore twice to two different points and it has not resolved the issue.

Thankful for any help!

We are using a website designed for Firefox, and when we use the "print" function within the website tool bar, on one of our PCs, it always defaults to a print preview which states "Printing from Win32 Application - Print". We have "print.always_print_silent" set to true, on this and all of the other PCs using the website, but only this PC has the issue. We can't figure out what is making it pop up the print preview.

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.

I'm up to the most current version of Firefox

120.0.1 (64-bit) Windows 11

For this and the last versions over a couple of years whenever I go to;

https://www.linkedin.com

Then try to go to any other page like https://nextdoor.com from a bookmark, it stays on linkedin.

If I enter the address by typing it in, it works.

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

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.

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.

Just a short time ago Version 125.0.3 downloaded. Since then I cannot open Youtube without it crashing. When I ask it to restore the tab (one of 2 choices offered, it crashes again. After 4 or 5 times I close the tab and switch to another browser. I shut off the one extension I had running. That fixed nothing. I looks like my 2019 iMac is too old and I need to go back to an earlier version.

There seems to be something specific to the Phlearn site and Firefox which prevents videos from auto advancing. They either recommence the just completed video or revert to an earlier one.

I have been getting a message that says firefox has something running and cannot shut down. I went into task manager and 'shut down' firefox, but the message keeps on coming. I then thought that I would uninstall it and then reinstall, but it tells me that it cannot uninstall because it is running, -"Firefox is already running but is not responding. The old Firefox process must be closed to open a new window." When I click on ' Close Firefox' nothing happens. when I click on 'Cancel' the message disappears, but will reappear. Then in desperation, I went into program files and deleted the Fifefox folders but it wouldn't reinstall. There is obviously somewhere a file/file which is screwing me up, does anyone know what this it?

Hello, I have the fallowing issue with Firefox and the sound icon on taskbar in Windows 10 22h2, when Firefox is open and I click on the sound icon on the taskbar in Windows 10 22h2 the sound icon does not open, when Firefox is closed the issue is gone.

Any help to fix this issue would be great.

Thanks

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.

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!

My firefox now freezes when I click in the URL bar. NO solution I have found so far other than task manager -> end task and restart the browser. Occasionally that will work, other times it will immediately freeze again.

Historically I have had a LOT of tabs open, more recently less than 20 tabs. I have never seen the issue before.

Windows 10 22H2 Ryzen 3600 32GB RAM Nvidia RTX 3060 LHR 3 Monitors 2 - 1920x1200, 1 - 1920x1080

What I have tried so far: - reboot - restart firefox - "refresh" firefox - troubleshooting mode - removed all extensions - removed some extensions - reduced tabs down to a few - tried to click in the start page search instead of url bar - turned off hardware acceleration - turned on hardware acceleration - turned off TLS DNS - using only 1 window at a time instead of 2 or 3 - waited for an hour or so and window did not become responsive

None of these solutions fixed the issue. A screenshot would be useless as the window looks fine, but the UI is unresponsive.
