Firefox Support Forum

I just wanted to let you know that your latest Update crashed my computer during the install, I had to use a different browser to download and install the latest version.

Errors are:

K Mode Exception not handled

RE: Ndu.sys

Hello, help in FRench would be welcome 'cause the faulty Firefox is set in FRench. So, as said : Unable to access ANY internet page with ONLY firefox under Win 10 It says "Attention : risque probable de sécurité" (probable security risk) Since the problem occured : - Firefox has been reinstalled and is up to date (104.0.1 64bits) - Proxy parameter has been set to NO proxy - Sync/Account has been disconnected (and unable to reconnect due to this pb) + Others Windows accounts do NOT have this problem On some servers, I can ACCEPT the RISK and access www but NOT on https://accounts.firefox.com

Code d’erreur : SEC_ERROR_UNKNOWN_ISSUER [Certificat] Nom de l’émetteur Nom courant AdBlocker Ultimate 2 (But this extension is NOT loaded)

Any help is welcome, thanks in advance !

HP laptop, Win 10 ver 21H1, Firefox 104.0.1 (64) Hi... I'm 72 so please type slow. This just started happening a few months ago... every time that Firefox installs a new update it takes forever for the first web site/page to open after starting FF. I can click on an existing bookmark or type in a location, go fix a coffee or drink, stop at the bathroom, return to my desk and the page/site still hasn't loaded yet. Fiddle with this, fiddle with that, click here or there... still no joy. Close ff, open ff... several times... nothing. What eventually works... click ff menu, click help, click get help, wait.. several minuets for the change from arrow to finger than click on anything listed. Once the window responds to my click everythings good and ff starts working again. All things considered... not a big deal, but perhaps you could suggest something that would speed up the process a bit... maybe a few less key strokes as my memory isn't quite what it once was when it comes to remember how I did something. Thanks...

Long time Firefox/Mozilla user. Installed/upgraded/migrated on Win, Android, Linux (various distros) over the years.

This might also be relevant to the Sync topic.

Built a new Win 10 system 11/21. Installed Firefox, logged in and Enabled Sync. Installed licensed Adobe photo editing software. No problems. Used for 2 weeks.

Spent 5 months in hospital.

Back home, used new PC for ~45 days; Win 10 went wiggy on me after an update - could not get to Settings menu ya da ya da. It went downhill from there. No identifiable hardware issues (tested memory and (.m2) boot drive, etc

Tried many fixes to Windows while trying to keep user data. Ended up reinstalling Win 10 (multiple times...). System working, but no bookmarks/passwords. Installed Firefox. Of course, it didn't work - understandibly.

Went to old PC, Firefox does not seem to give me the option to *see* my login password); looked up Firefox password (I hated to do it, but with ~500 userid/passwords, I started to let FF manage these a few years back). Found it. Went to new box and logged in. Password error. Digging deeper, it *appears* that the present password was set circa 2015 and the Firefox saved password was set circa 2021.

I've now been fussing with this a week. Searching, searching; trying pretty much everything I can think of. Nothing works.

Any path forward besides changing passwords on all of the involved (~20+) devices?

Now I need to try to recall where I put the recovery key ... (yes, I have since embarked on an extensive backup/restore point campaign which includes backing up backup system software).

If you don't write an answer here publicly, on how to disable updates and stop all pop-ups and automatic downloads of said updates, i will come to your offices within 2 weeks and do something really bad.

Right now I'm giving you a choice. It's all in your hands what happens next. Will you write me an answer for all to see...or will you delete this. Live with the consequences.

Dzień dobry,

Od czasu jednej z ostatnich aktualizacji, przy każdorazowym otwarciu nowej karty przeglądarka wiesza się na minimum kilkadziesiąt sekund, czasem trochę dłużej. Jak już się "odblokuje" to pracuje normalnie, płynnie, problem występuje tylko przy otwieraniu nowych kart, jest jednak dość irytujący - prośba o pomoc.

after PC format at 05.09.2022, i installed Firefox and loged in my firefox account but i did not get back additions which i used before and my web site accounts and their passwords. i dont know what happend. what should i do to fix it. please help me about it. thanks.

If i have one tab open, it closes. If I have multiple tabs open, the one on the email page closes. Reading an email or opening an attachment does it. Maybe other things, not sure, but just on that page. Thanks.

I have a website made with Wix. I have never had problems watching the videos uploaded there until the last update of FF. I can see all the old videos completely but only partially the new ones. That is strange. I asked Wix, and they told me their app works better on Chrome and Edge, so I opened my site in Chrome and Edge and the videos played complete. This problem happens in my PC and in my Android, and only with the last videos I uploaded to my site, which are mp4 type. The site is personal, so I hesitate to give the address to any not related to me, but this time I'll trust on FF volunteers and hope they will act professionally. The address is https://rdz.rocks and the last 2 videos are on My Hobbies/My Music/Christian Music/Vida Eterna and the problem is with the last 2 ones.

Google My Business won't allow photo uploads while using Firefox. I manage our maps listings in Google and for the past few weeks, they will not allow it. If I switch to the dreaded "Edge", there is no issue. Please share any work-arounds for this.

Hey guys.

I have this weird issue, and I was unable to find anything on it through Google.

When I start Firefox and then go to YouTube (either via bookmark or by typing the URL) I have an odd issue. The front page of YouTube works as it should. I click a video, and that also works as it should. However, when I try going backwards to the YouTube front page, an issue arises. It happens whether I use the mouse shortcut or the button in the browser.

Instead of going back to the front page, it just reopens the same tab I'm on. If I go back once more, it takes me to my browsers home page. I THINK this has something to do with the "mini player" on YouTube not working correctly, but that's just my theory. I haven't been able to fix it. This doesn't happen with Chromium. I also haven't seen the mini player at all for a long time. I'm unsure if that stopped showing up when this issue arose, since I've just accepted it for a long while. But it is very annoying.

I do use uBlock origin and SponsorBlock, but I've had these for ages, and as far as I remember the issue started before I installed these. Uninstalling them is not an option, they're just too good. These are the only extensions I have enabled apart from RIF, which shouldn't interfere with YouTube.

Has anyone else had the same issue, or can anyone suggest any way to fix this? This also doesn't happen every time, but it happens frequently.

Thanks for any replies.

There was an issue with accessing the network for media playback. The sub-error code will contain what specific resource was unable to be accessed over the network. | NETWORK_ERROR encountered, code: 1400

Every time I play video on you tube there is 3 sec delay and each time I forward the same video happens every time.I was with the geek squad from Best buy and they were trying to fix it and on the end they told me that it is with fire fox and i need the help from your support tech.

I was away from my desktop for a few months. During that time, I sent a number of tabs from Firefox on Android to my desktop. I've just logged into my desktop, updated Firefox, and synced, and 0 tabs came through. There were some errors in about:sync-log, which I don't see a way to attach, but here are some representative lines: 1662515573549 Sync.Status DEBUG Status.service: success.status_ok => error.login.failed 1662515586056 Sync.Telemetry ERROR Notification for engine tabs but it isn't current

Is there any way to get those tabs back?

I have Firefox v104.0.2 and am running a Windows 10 computer 64 bit. When attempting to log into my Edward Jones financial account, every item on the web page responds to me except secure login. It worked properly yesterday 9/5/2022. I restarted my computer, cleared cache, etc and I am running a VPN. When I could not login I contacted Edward Jones and they said that issue happens once in a while. I am able to get the site to work with a VPN and Chrome without issue. Why am I having problems on my Firefox browser? Any help would be appreciated.
