Firefox Community Forum

i have a big problem with settings of privacy and security. the problem is i cant edit this option ( Allow Firefox to automatically trust third-party root certificates you install ) and its greyed out . i made everything ( refresh - troubleshoot - uninstall ) and with the first click on singing my account on Firefox and add my restore my add-ons after setting up windows this option become unavailable (greyed out) and cant edit it. i need a solution without going to set up a new windows because its so tiring to set up a new windows to edit this option. please give me a solution its emergency. thanks a lot.

All of a sudden, I can't access several websites through Firefox that I have used for years -- but I CAN access them in other browsers, like Chrome and Safari. Also, Firefox no longer works with my password manager. Until about two weeks ago, I could always autofill login information, but no more.

What gives? I am up to date on my IOS (Sequoia 15.5) and on my version of firefox -- and my password manager app. Superfrustrating. I hate to have to turn to Chrome as my primary browser since I hate Google, but I might end up doing that and just not using Firefox anymore, after like 20 years of having it as my primary browser.

After my bitwarden add-on failed me, I remembered ChatGPT helping me with this another time - but I got it wrong. I right clicked the extensions button (I have 3 add-ons falling under that button) and removed from tool bar, thinking I could then reinstall it and the Bitwarden issue would rectify.

Instead, the extension icon disappeared, and is nowhere to be located. ChatGPT wants to do some reconfiguring but surely there's a better way. I have looked in "customise toolbar" (ie, right click toolbar, click customise toolbar and look for the icon" - but the puzzle piece icon is not there.

Surely I have hidden the puzzle piece icon somehow and I need to do some sort of magic to make it reappear... Have never had this issue with Firefox previously.

This is the message I receive when I try to sign in to my Adobe account online:

Hmm. We’re having trouble finding that site.

We can’t connect to the server at auth.services.adobe.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

How do I check that Firefox has permission to access this page? Or, what else do I need to do to sign in to my account?

Thank you!

I am old-school security conscious & have been using FF since its inception. Really. Clear my cache & delete browsing cookies on a regular basis. I use a private window for shopping and q&a info gathering. Recently I saw Walmart.com showing up in my cookies and couldn't figure out how/why as I *only* look at Walmart in a private window. Today I realized Walmart has managed to bypass the private window options and place cookies anyway! To say I'm furious about this is an understatement. I have adjusted my settings to "Strict" but it's still able to bypass the private window and is staying on my computer. I am updated to the most recent FF version; running MacOs Sonoma 14.7.7 which was just recently updated; I'm not going past this one for now but that really shouldn't be the issue. This is most definitely a FF issue and one that needs to be rectified not just because it's Walmart but because if they can do it so can others soon enough. This cannot stand.

When I have multiple tabs open, around the 6th tab, the entire computer freezes. I have to press the physical button to shut down and restart. This behavior started with the last Firefox update. It doesn't happen when I use Brave browser. What changed to cause this?

I'm running Mozilla Firefox for Linux Mint mint 100 - 1.0 version 141.0.3 (64 bit) on Linux Mint 22.1 Cinnamon. These are the latest versions of Mint and of Firefox for Mint.

I am now receiving this notice for more and more commonly accessed websites. I get the message if I have https only selected or not selected. Currently receiving for Lowes, Home Depot, American Airlines and more. I can go to a Firefox 135.0.1 browser on a separate desktop accessing the internet through the same router and do not have issues. I suspect I have been upgraded by Mozilla into a less functional browser version for whatever reason that Mozilla does this.

Sample Messages:

Since Flathub list the org.mozilla.firefox app as official, i hope this is the correct support channel.

Recently i switched from distro specific package managers to flatpak as my application provider. The firefox flatpak won't play most embedded Video/Media on applications like in-browser fediverse clients, forums, blogs or wikis. Youtube works without any issues, Twitch is fine until there is an adbreak. Then it sometimes stops with the supported format/mime error (screenshot appended), only recoverable by cache-dismissive reload.

I used this Article https://support.mozilla.org/en-US/kb/audio-and-video-firefox and the links it contains to debug without any success. None of these samples play. just shows supported format/mime error https://test-videos.co.uk/bigbuckbunny/mp4-h265 At this test website 1. and 3. example won't play. I provided a screenshot before and after trying to click play on all the examples. https://www.tekeye.uk/html/html5-video-test-page

Contrary to the observed behavior about:support#media claims Software Decoding supported for everything except HEVC.

Chromium Flatpak has no such issues. So i copy the video url and play it with chromium. You can see: dire times.

Just updated to FF 141.0.3. The browser had advised me to restart to finish the update. So I did. But in doing so, not all my tabs were recovered.

Most were, but like 3 were not.

What happened to Firefox's permission's page? There's so few options now. I'm being harassed by websites to give them permission that should be blocked across the entire browser. I'm autistic and sensitive to popups/interruptions/distractions. So most permissions I simply had off for everything, because I don't want to be asked anything. I don't want to confirm anything. I don't want any popup of any type. So I turned everything off and it was good. (except blocking cookies of course)

But now sites are asking me again and there's no way to blanket turn off everything. I see I can press "Ctrl+i" to bring up specific permissions for that site, but that's not good enough. I specifically need permissions blocked for sites I've never visited. Needing to visit the site first completely defeats the purpose.

The permissions listed in the settings isn't all of them. How do I turn off ALL permissions for ALL sites. I can turn on specific permissions when I want them. Essentially, how do I recreate functionality that used to exist but was removed from us for whatever reason.

Also, it's a huge security hole! I'm a senior full stack developer. Asking permissions for a user is a great way to fingerprint them. If I accidentally hit "yes" to a few key permissions, I can be fingerprinted. Another reason I should be able to blanket ban these permissions. I just want my browser to be a browser. These permissions do nothing for me but make the experience worse.

I did some research recently on some travel sites.

Today, while trying to research which tab was doing DNS queries to SnapChat (which I never use) I learned about `about:processes`. I found 5 "hidden" tabs from various travel sites (some of which I never visited) running in the background. I did not explicitly hide any tabs.

WHY IS IT ALLOWED FOR SITES TO KEEP OPEN HIDDEN TABS AT ALL WITHOUT TELLING ME ABOUT IT?

This is not conducive to trusting Mozilla.

I am so tired of the stupid banner popping up every time I put something into full screen, that says "press escape to exit full screen".

Is there a way to disable that?

I am on a windows 10 PC.

I HAVE UNWANTED SEARCH ENGINES AND KEYWORDS THAT I DID NOT SELECT NOR INSTALL AND CANNOT BE DELETED. (everything but google)

PLEASE EXCUSE THE CAPS WHEN I HAVE TO REDUE THIS ASK A QUESTION THINGGY THREE TIMES TO GET IT TO TAKE AND POST THE QUESTION I GET A LIL PISSED....

Any help would be GREATLY appreciated.

An irritated FF user in Ephrata PA.

Specifically Youtube videos, Youtube music songs and nothing else either never load (95% of the time), load only the first 10 seconds and then buffer or load partially after ~20 minutes. No error messages. Only in Firefox.

I tried: Reinstalling Firefox Switching profiles Disabling all extensions Running in safe mode Clearing site's cache and cookies

It's been like this for a couple of months. Been circumventing it by playing videos in a different browser, but would be nice if there was a fix.

Attached image with a loading screen (lol).

It's a repost btw, posted 2 weeks ago and got 0 views.

For some reason, I was unable to verify my account. I even thought I was wrong with my password, but that was not the case. When I use a different browser, Apple does not just ask me for a password but also a key; however, this option was not available on Firefox. With this, I can't log in to my iCloud on my Firefox Linux app.

Since updating Firefox on June 30, 2025 on my Dell desktop computer that runs Windows 10, most of my bookmarks are no longer visible. Only four of my bookmark folders are visible and most of their contents have disappeared.

However, 1) my uncategorized bookmarks - those in "other bookmarks" are still visible, and 2) If I go to "Manage bookmarks" and do a search, I can find all of my bookmarks including those that are no longer visible.

In addition, I can no longer add or delete bookmarks. It looks like I can do add a bookmark and it will let me go through the steps of adding a book mark - it even says I can put it in all my old folders that are otherwise no longer visible. But one I complete the process the bookmark does not show up.

I have read multiple Firefox Help articles about disappearing bookmarks and have taken all the steps suggested including: - Attempted to restore backups of bookmarks - didn't work. It shows me the multiple old backups but when I try to restore one I get the message "Unable to process the backup file". I have tried it with at least four of the old backup files - all without success. - cleared cache - did troubleshooting mode - refreshed Firefox - uninstalled and reinstalled Firefox - looked to see if I had a different profile other than my default profile that I could switch to. I do not see another profile.

Nothing has helped. Any suggestions would be greatly appreciated.

Thanks

Hi. News videos from www.bbc.com won't play. When I ask the BBC website to play a video, I get a blank area of my screen, with a play button. Clicking the button makes it go away, leaving me with just the blank area of the screen. Videos from youtube, movie trailers, etc play fine - it's just videos from a few sites (such as BBC) that yield nothing. I have autoplay videos disabled by default, but: I'm not trying to have the website autoplay; The setting doesn't affect other websites; and there's no way to disable autoplay for the website I'm on (no way I can find, at least).
