Firefox Support Forum

Hi all. Did a search but found nothing that helped. Just updated my Fedora 36 workstation and tried to play videos in CNN and MSNBC web sites and get the error message: "Code: 4 | Message: Something went wrong during native playback." I am using the latest Firefox WEB browser. UTube videos are playing fine. Someone has stated on the Fedora forum that they have the same problem but has no problem in Chrome on the same machine. Any ideas? Thanks in advance. Bob BTW, this happened in two machines running Fedora 36 and Firefox 101.0.

I was using Firefox on windows 10 laptop, everything was synced with my account. Now after switching to Ubuntu I can't see my bookmarks, Just an empty toolbar. Now I don't have access to my old laptop, I sold it.

Any help?

Firefox wasn't working well on a seldom-used laptop, and the update to 100.0.1 didn't go quite right, so I deleted the old version and (using the odious Edge) tried downloading a fresh copy of the software.

But then I get a message from "7-ZIP" that reads "Can not create temp folder archive"

I'm stuck. Advice?

Instacart webpage suddenly will not display/open on Firefox but can display fine on Chrome. Instacart App on mobile phone works fine, just won't open in Firefox. Any suggestions other than using Chrome? Firefox version 101.0.1 Windows 10. Was working fine until latest update installed this morning.

Hello, I experience a XUL Runner error message after attempting to update Firefox and in following the guidance to rectify the error deleted the Firefox folder including the bookmarks. Is there anyway of recovering the bookmarks (maybe with a third party program) or are they lost forever? Thank you.

Getting error SSL_ERROR_BAD_CERT_DOMAIN on all my sites that are signed with a SSL Cert from my internal CA since updating past version 99

This appears to be a bug starting after Firefox version 99 on Windows because after i upgraded to Firefox version 100 i started getting this on all my SSL Certs from my CA and they worked fine prior to the update. Can anyone confirm if something changed after version 100 that is causing this?

Thank you.

After upgrading to v101, Firefox no longer recognizes my Self-signed wildcard SSL for *.local.dev.

Before you tell me not to use the .dev domain, I am aware that Google owns it and we're technically not supposed to do local development with the *.local.dev domain.

I have already tried the following: 1. Set network.stricttransportsecurity.preloadlist to FALSE, and everything was working perfectly fine before v101 2. imported the server.crt into Trusted Root Authorities in Windows, and also imported it in the Certificate manager in Firefox. 3. Tried other wildcard local domains like *.test.site, *.local.ddev and these don't work either.

I even tried following recent guides to issue a new certificate with openssl and SAN, and it still doesn't work.

Screenshot of wildcard SSL attached.

By mistake, I deleted my ESET Password Manager extension. When I went back to Firefox extensions to put it back in, I cannot find ESET Password Manager listed. How do I reinstall it?

Whenever I attempt to access DRM content such as netflix or spotify I am notified that the WidevineCdm plugin has crashed. I'm running firefox version 101.0.1 on Kubuntu 22.04, I am running the debian package release, but I had this issue with the snap version too. I've submitted crash reports, but they're all "EMPTY: no crashing thread" (https://crash-stats.mozilla.org/report/index/20af09a5-6bc4-4719-9242-38f5c0220614 here's one).

Have just been given the security warning for a site www.solar-thailand. On using the advanced button I am told that " Firefox does not trust this site because it uses a certificate that is not valid for www.solar-thailand.com." and that the certificate is only valid for (list of sites): "The certificate is only valid for the following names: sim456.com, www.sim456.com, dodeetoday.com, home-dd.com, solar-thailand.com, service-thailand.com, dcspump.com, cable-thailand.com, led-thailand.com, tp-scg.com, 3d-thailand.com". Am I going mad or does the site actually exist in the list??? If someone could please explain this I would be very grateful. Thanks in advance, Peter.

I am using Firefox Version 101.0.1 (64-bit) for Desktop Windows 10 64bit (newest version (see question date for lookup info)).

This problem I could not find anywhere in this Firefox self support community. I think I discovered a bug in the firefox settings, but it might just be me missing something, but I doubt it, being familiar with the settings and them being clearly worded.

I can not seem to get my firefox to save the website always allowed to keep cookies stored between sessions (and their cookies / other data obviously also don't get saved between sessions). - maybe there arises a problem with the setting of never saving history between sessions?

Please, have a look at my current settings below (two screenshots): <image 1 (longer one)> <image 2 (shorter one, custom history settings)>

The settings being written as they are should mean that the always allowed websites should never have their cookies deleted between sessions, regardless of their history (their being visited) being deleted. To me this is frustrating and appears like a bug and not a feature.

Maybe is history is deleted all site permissions and data get deleted, too? - (If yes, that is clearly not what the settings suggest, and if it is supposed to work like this, I strongly suggest the Firefox Dev.s team to fix the confusion or add some feature work-around to suit my use-case. The internet is not a safe place anymore, generally, but some parts are, let me trust your settings do what the say they do, at the very least. Thanks in advance.)

Firefox says I need a video codec to play a video (that is aparently somewhere on the page). It does NOT tell me what video, what video format, or what codec I need. How do I find out what codec I need?

Firefox version: 101.0 (64 bit) OS: Fedora 36

In the bookmark-bar in my Firefox-installation contains the soft-button for the function "Import bookmarks". I do not need this function always showed in the bookmark-bar. How can i remove it ?

My bookmarks toolbar is empty. When looking through the bookmarks menu, it shows that none of my bookmarks have been removed, and they are all still listed as being present in the Bookmarks toolbar, but they are not displayed in such. To be clear, bookmarks toolbar is enabled, and I have already verified its positioning in the customize toolbar pane. There is a strip of empty space where they used to be, but they are simply missing now. How do I fix whatever issue caused the toolbar to cease displaying my bookmarks?

Comments below youtube videos won't load. This happens across all browsers on this computer regardless of add-ons or being logged into youtube.

I've attached a screenshot that shows that 176 comments are below that video but none load. I'm using the latest Firefox version on Windows 7.

If you need any extra information I will gladly provide it.

My old 2009 MacBook Pro broke, got fixed, and now the backup won't transfer. So I need a new Firefox.

OS X El Capitan V10.11.6 is the latest this old computer will handle. On the mozilla.org download page, the app on the .dmg that gets downloaded says it wants OS X 10.12 or later.

I'd appreciate your suggestions.

When I look up the error message I get, everyone I see who got it can't open Firefox, but I can open it fine. For me, I have Firefox as my default browser and when another program (tModLoader on Steam) tries to open it, it gives me "Profile Missing," "Your Firefox profile cannot be loaded. It may be missing or inaccessible." I don't know if it gives the same error for other programs because I can't think of any programs that open my default browser. When I switch my default browser to Edge, the program can open Edge fine.
