I want to delete all my web certs except for the top seven, which cover 99.32% of current web certs. I specifically do NOT want the EU Cyber Resilience Act to have the ability to insert their certs into my root store, enabling their member countries unfettered power to compel acceptance of their certs.

I tried following https://wiki.mozilla.org/CA/Changing_Trust_Settings, but this must be for an earlier version. I don't seem to have an Options/Preferences window. On the other hand I am pretty old & maybe just can't find it....

Any hints on how to do this?

Firefox since 102 or 103 has a giant issues with gifs, movies ect after resuming from hibernation. In the Dev mode there are errors like this:

MediaLoadExhaustedCandidates = no any media can be loaded

Invalid URI. Load of media resource %S failed

Why does it happen only in firefox? Even in FF 120 Windows.

between this netflix error, this amazon alert, and youtube auto switching to 360p it's become increasingly difficult to access media. i've called netflix about this and they had no idea what the code was and have not gotten back to me with a resolution.

does anyone know what's causing these issues? is it just companies being hostile to firefox specifically or is something wrong?

i've cleared my cookies and cache, i've restarted several times, i've logged in and out of everything. i'm on version 120.0.1

So I've noticed that after putting my computer to sleep, upon return Firefox will be unable to load any videos from seemingly any site. The temporary solution to this is to reset my computer as sign offs, locks or returning to sleep do not clear the issue. I've tested on different browsers/sites and can confirm that this is exclusive to firefox. I have booted firefox in troubleshoot mode, cleared my history and given the sites time to load with no luck on any of them.

Is there a solution to this?

Hello, can you add better support playback on .mp4 videos? Seems with Firefox it's a hit-and-miss with some .mp4 videos that will play and some that will just show "No video with supported format and MIME type found".

All other browsers will play .mp4 videos without an issue but Firefox won't.

If you can provide better .mp4 playback support that would be greatly appreciated. Thanks

Here's one of those videos for an example: https://drive.google.com/drive/folders/1Fv6SdftiCXeYPQOdF17H2JNpwjMu9P7q

Pretty much a URL string like example.com/videosample.mp4

Thanks guys for screwing up my day with your latest update. I used to be able to download a .pdf and opening it in my ,pdf reader. I NEED to do this for tax reconciliation purposes. Now your crappy program has decided to open .pdfs in itself and I cant get a downloaded copy any more. What the hell was the programmer thinking? Yes I have gone to Applications and checked that it is set to my .pdf reader. Please fix this before I get fined by the tax office.

I want to use the search field for search and the adressbar to enter adresses. Unfortunately it doesn't let me enter adresses, they all get routed to a search provide (google) and I can't acees my router

How can I dsable the search in the adressbar?

Setting browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar (are you kidding me?) to flase does not help

I want to find to get rid of this or find the source of this so I can delete it.

In "about:policies" there are 2 Active Policies: "DisableTelemetry", and "DisableDefaultBrowserAgent" Also, in "about:policies" I'm not sure if it's related, but there is a long list of policies there too.

On spotify web player in firefox there is a delay after skipping 15 seconds forward or backward in audio. Only on bluetooth speakers. But doesn't happen on Chrome. Anyone got a fix or can help?

Machine is Windows 10 with a Logitech wireless keyboard. Latest Firefox browser. Not always but sometimes when using Firefox browser to log in somewhere or enter data on some web site, I'll get an incorrect entry for a key stroke. e.g. I enter a 0 and get a 1. But if I enter a 1 I get a 1. So far the error key has always been different.

I've tested things by launching a notepad or Word document and entering the character and in those all works fine. But go back to Firefox and I get the error again. What I have to do is to close and re-launch Firefox and so far this fixes things. It's an intermittent problem which forces me to keep another browser on the machine and ready. Imagine entering a password when all of a sudden you type 'X' and it gives you an 'E'. Really frustrating!

I followed the instructions at [[Unload inactive tabs to save system memory in Firefox|https://mzl.la/3AdRbLx]] but I still occasionally see the tab refresh when I select it. I start with a search on Bing, click an article to open a tab, follow links from there, back to the first tab and select another. I repeat this until there are several tabs open. Sometimes the page refreshes when I switch back to one that I previously reviewed. Is that controlled by the option browser.tabs.unloadOnLowMemory? if so, it doesn't appear to be working. [Edit] - The last time this happened I checked my system and found 10gig used of 64gig installed. I'm using the most current version of FF 120.0.1 on Windows 11 Pro v 22H2.

Hi,

Today, Firefox appeared to freeze as I was trying to sign into my Hotmail account and then crashed. Subsequent attempts to restart Firefox result in crashes. Usually immediately, sometimes after about a minute.

I have tried "refreshing" Firefox, running in troubleshooting mode, and uninstalling/reinstalling. I also performed the memory test suggested and had no errors.

There are no crash reports in the "Crash Reports" folder.

I have Windows 10 Home, Version 22H2, Build 19045.3693 (not sure if this is helpful or not)

Since snap firefox keeps crashing somehow, it just hangs.. i cleared cache and all, reinstalled it, but still.. ?

They say linux is a broken system (:

Firefox has always maintained that current tabs will be restored after a reboot of the browser, and indeed that was the case for the first half-dozen years I've been a subscriber. That has not been the case for the past 4 - 6 months however. I have the correct Settings for this, so it is not on my end. Why do I always get a fresh Firefox browser whenever I update the version (which is quite regular lately . . . maybe a new version of Firefox every 3 weeks). Please help.

i use New Tab Override, reinstalled my software, firefox, and lost the button to get a new tab that goes on the address bar. its no longer in customize. ive removed the addon and put it back on, started in troubleshoot mode, disabled all other addons, and it never showed back up

can someone help, the guy who made it wont help

Hi, I am using Firefox vsn 120 for Linux Mint. I believe that I have the privacy and security set with the default settings.

However, Firefox seems to forget the information stored by websites, so that can't simply login.

Each. And. Every. Time. I have to go through the process of re-introducing myself to the security of the website provider who insists on sending me emails, SMS messages, etc. with codes to confirm who I am.

This applies, every time I use a site that requires a login (bank, BBC, Fidelity, eBay, Facebook....).

Once I have been approved on a site, then my login seems to work for a few days, up to a week and then off we go again with a new set of security codes. My settings do not delete cookies, and firefox is never closed, except if the PC needs a reboot, which is rare.

I would appreciate any help in settings that would allow me to use Firefox normally without having to enter security codes. Cheers, Mark

Oddball minor problem I've encountered on a recent update of Firefox, but also I switched keyboards at the same time, so I'm not sure which causing the problem. I'm on a PC, using an MSI keyboard. Ctrl and Shift keys all work, the ONLY combination that doesn't work is (left) Ctrl + (left)Shift + P. Other Ctrl + Shift key combinations work. If I hold the right Ctrl and either shift, P works fine. If I hold the right Ctrl and the right Shift, P works fine. (left) Ctrl + (left)Shift + any other key shortcut in Firefox or elsewhere works, it's ONLY the P shortcut and only in Firefox and only with the left two ctrl+shift combo that doesn't work.

Any ideas on what is causing this and how to fix it?

Is there some way to enable and disable specific config settings , on a per-site basis?

For example, let's say I want to disable right-click hijacking (dom.event.contextmenu.enabled) on turtlesaregreat.com, but use the default settings everywhere else.

The Page Info > Permissions panel has some, but not all the ones I want. Is this somehow built into Firefox, or maybe there's an extension?

Thanks.
