Firefox Support Forum

I couldn't get the crash data at all. But I managed to get this from the Terminal;

[Child 10502, MediaDecoderStateMachine #4] WARNING: Decoder=7f0fd7cf1400 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - RefPtr<mozilla::MozPromise<RefPtr<mozilla::MediaTrackDemuxer::SamplesHolder>, mozilla::MediaResult, true> > mozilla::MediaSourceTrackDemuxer::DoGetSamples(int32_t): manager is detached.: file ./dom/media/MediaDecoderStateMachine.cpp, line 3470 Exiting due to channel error.

Figured out the basic issue (from Solutions here) why old Firefox not working on old XP-SP3. Found 52.9.0esr download - but when I run the file, it keeps telling me to "Close Firefox". Used Task Manager - nothing - not Firefox or anything else - is shown to be running. Any ideas? Might not be a Firefox issue, but would appreciate any insights. TIA - Jean

I was using one of the old Firefox ESR versions (can't remember exactly which) because I was still on an old Mac OS version, 10.9 to be more specific.

I recently updated to macOS Sierra 10.12.6 and as a result, as soon as I opened Firefox, I went to check if it would update on its own and it did. It updated to version 91.6.0 esr. After this update, something weird happened: the browser won't load any page.

I checked, it's not an internet connection, because other browsers are working normally. It won't load any extensions either. So I want to fix this issue with an update.

The question is this: I remember installing what was called Firefox Quantum. As of now, the name on the about section is just Firefox Browser, maybe because of the updates. • Can I install the latest "regular" Firefox 97.0 on top of the this old installation, just using a standalone dmg file? • Will this installation preserve everything that's already in the browser? By everything I mean bookmarks, extensions, history, cookies, etc.

It seems to me that the automatic updater isn't installing version 97.0 on its own because it's coming from the ESR versions. So it's stopped at 91.6.0 esr.

Thanks in advance

I've written about this before, but no help? I'm using Firefox Mac 78.15 (up to date). When I go to CNN and select a video, a thumbnail (still image) of the video appears, but no player with controls, so no video. When I do the same on Chrome, I get a video in a video player, which plays just fine. Also, all other videos on FIrefox (YouTube Fox News, etc.) play just fine?

Trying to play video included in Amazon Prime subscription. I received a warning from Amazon about 2 weeks ago that After Dec 6 I would need the latest Firefox update. I updated. Now as shortly after video starts to lord, I get a message in a box that says I need to upgrade Firefox to play this video. I have checked the "about Firefox" tab and it says I am up to date. I am running 91.4.0esr and checkbox says I am up to date. ????

Firefox open tweeter's tabs only in private window, can i so something to fix this and be able to open it even in standard window please ?

im on mac os X 10,9,5 with firefox 78,15,0esr

Could you please have a look ?

Thank you

Has Mozilla stopped processing crash reports for older versions of Firefox like Firefox ESR v52.9.0 (the legacy version for Win XP and Vista)? I tried to filter crash reports on the Mozilla Crash Report site at https://crash-stats.mozilla.org/home/product/Firefox for older versions of Firefox but I can't select a Firefox version older than v68.4.1 (i.e., the current FF ESR version) - see attached image.

I'm trying to assist a Vista SP2 / Firefox ESR v52.9.0 user who is trying to troubleshoot their browser crashes but they've told me they are having problems submitting their crash reports from about:crashes. I just want to make sure that Mozilla is still processing crash reports for older version of Firefox if the user submits them from about:crashes manually, assuming the crash report is less than 6 months old.

64-bit Win 10 Pro v21H2 build 19044.1466 * Firefox v96.0.3 * Microsoft Defender v.4.18.2111.5-1.1.18800.4 * Malwarebytes Premium v4.5.2.157-1.0.1562 Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620

Since 91.3esr update, over a period of a couple of days, if I open the Windows 10 hidden icons I will see a large number of FF icons that disappear immediately after I hover over them. Are these FireFox icons (see picture attached)? I also note that FireFox left untouched will be using 25% of my 32GB memory growing over a period of time. When first opened (I have restore previous sessions option selected), it is minimal memory usage.

Firefox will not load dropbox except the top left corner sometimes, even with ghostery paused. There's no problem on Microsoft Edge at all. Anyone else experiencing this?

I am using version 91.5.0esr (64-bit). Virtually always, the download status shows as failed. Yet, there were files created by the download. I have even been able to go back literally months in the downloads history, click to retry each download, which is then showed as being successful. I did NOT reload the pages whose content I was trying to download. I realize that a browser tends to have a cache, but surely not that big. I'm guessing that showing the status failed is some type of error.

Hi there,

Firefox is my daily browser and a few websites are causing recurrent issues. Aliexpress randomly switches language and currency, but the most annoying problem is that it doesn't let me change it (clicking on it doesn't give the menu it's supposed to give), and searching any item in the search bar just gives the "spinning star symbol", and nothing else.

Similar issue in eBay: some menus just don't open, including submenus in the "Contact seller" form, which cripples the whole experience.

As a comparison: all these websites work fine in a slightly outdated Safari 14.1.2. and the most recent Vivaldi.

Now, I saw the issue being mentioned here 4 years ago.

What I tried:

1. cookie /cache cleaning, which I did to no avail.
2. Safe mode: no change
3. Switched back privacy settings to "Standard": no change.
4. Manually copied files from one profile folder to another: as could be expected, no change.
5. I even tried a full refresh, but with extensive customization already performed over the years and most of it either in about:config or extensions, I couldn't spend the time re-setting everything back to normal.

FWIW a list of all files and folders shown in my profile folder. I specifically excluded the "known good" files (see step 4). Interestingly, FF also generated an "Invalidprefs.js" file.
