Firefox supportforum

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.

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?

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

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.

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

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?

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

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!

Hi Support,

I have always been struggling with the idea of syncing two devices, that is main and secondary devices, and that when logged out of the secondary device, user details such as passwords, booksmarks and other important things are left bare on that browser or secondary device.

It is my believe that, after completing whatever task that led users to sync both devices, the moment the user logs out on the secondary computer, or any of the computers, the passwords, bookmarks, history and other essential details should not display again on such computer or browser anymore but apparently thats not the case with Mozilla Firefox browser.

Kindly look into that and work on it....THE SECURITY AND SAFETY OF THE USER IS LEFT WIDE OPEN!!!

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)

When viewing any tiktok account profile page, for example this one , the videos do not show up, and says "Something went wrong, Sorry about that! Please try again later."

Here's what i did:

1. Created new Firefox profile with default settings and no extensions
2. Visited a TikTok profile, and saw it opens as expected
3. Changed privacy.resistFingerprinting to true
4. Refreshed the TikTok profile page, and the error message shows up

I opened the console and compared and there were new warnings:

• Blocked https://www.tiktok.com/@tiktok from extracting canvas data because no user input was detected.
• Get user detail failed for getting wrong response

And 3 errors, when there were 0 before, all three read

• Uncaught TypeError: _0x5e9eb8[_0x2bd187] is null

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.

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.

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.

Video on https://www.abbeyroad.com/Crossing is suddenly unable to be played after to last Firefox update!! This has happened several times in the past but after 2 or 3 days it suddenly will start working again!!! It's been over a week this time and no resolution yet! Note following LARGE ROTATING X is: "The media could not be loaded, either because the server or network failed or because the format is not supported." Same note as in the past but eventually disappears and video works just fine. The video is a live shot of the Abbey Studio's Crosswalk (ie, the one shown on the cover of a Beetles Album years ago).
