Firefox Support Forum

I've been trying to sign in to pinterest, duolingo, etc using the 'sign in with google' option since my account was saved there. Whenever I click it, a sign in window opens up as usual, but it only ever shows a blank screen. No matter how long I wait, nothing shows up. I tried clearing cache, and it still didn't work. It worked before, but recently since the past 2 weeks, it became like this and I don't know how to fix it.

I have some extensions on my account so I'll list them out just in case one of them is the one making this problem: -Search by Image -Firefox Relay -uBlock Origin -DuckDuckGo Privacy Essentials -TWP - Translate Between Pages -Ecosia

(Below is a screenshot showing what I mean by the sign in window being a blank screen.)

Hello, I always use Firefox logged into my Mozilla account.

Yesterday I went to a (legitimate) site, that I had never visited before and only read one page. I didn't click on anything on that site/page, I only read that one page and left the site. Not long afterwards, I received a promotional email from that site stating "Thanks for stopping by!".

My question is: how did they know my email (the email used by my Mozilla account)? I have never received emails from that site, and as I said, I never visited it until then.

Does Firefox expose the Mozilla account email when visiting sites? This is pretty troubling. I would appreciate any input you have. Thanks

Hi - I just reset my PC and trying to restore Firefox. I saved the default release folder (qejikze4.default-release-1669319412153) which contains the latest bookmarks in the "bookmarkbackups" folder. I tried to just replace the bookmark file in the new install (how I previously transfered them), but I can't find the files in the latest V.120 version. Any suggestions on how I can do it?

Thanks

I have been receiving the following error code 'PR_END_OF_FILE_ERROR' on several website on my Firefox browser. Sometime, not all the time, I get the same error message while trying to use YouTube, while other times the site loads but says that I am offline and no internet connection. I have done all of the fixes that they say to use online and nothing seems to work. YouTube will occasionally work but none of the thumbnails will show up. Then there are other site that work fine.

Everytime I go to play games on my laptop I close Firefox for the extra resources and when I'm done I open it right back up, I have done this for YEARS but this time it didn't restore my session. I thought it would be as easy as the last time where I'd go click the Restore Session button but it isn't there so I spend two hours looking for solutions and found nothing. I don't know how this happened nor do I understand how this could happen in the first place, my Firefox hasn't crashed in months and I had already closed and re-opened it several time today.

I am using Firefox 120.0.1, and I have difficulty to take screenshot.

I tried to press shortcut key and button in toolbar as shown in the attached image, but they didn't work.

Is there any good way to fix this problem without reinstall firefox app?

Hi!

I'm on a newer laptop with an AMD CPU (with its own integrated GPU) and an Nvidia GPU.

When changing Firefox to "High performance" mode in the Windows 11 settings (System > Display > Graphics), it is said to use the dedicated Nvidia GPU. However, to my surprise, this is noticeably more stuttery and laggy than having it use only the integrated AMD GPU ("Power saving" mode).

Additionally, Firefox's hardware acceleration (General > Performance) is set to "use recommended", and my Windows 11 Power mode (System > Power & Battery) is set to Balanced.

I was wondering what the best way to configure all these settings is, such that it takes advantage of my hardware as much as possible? I wish to understand more than simply switching options until Firefox looks the smoothest to my eye --- what do these settings actually do, and how should they be configured idealistically?

I also sometimes run Linux, where things are a bit more complicated (e.g. Nouveau vs proprietary drivers, PRIME, etc) so I understand if the answer is less certain in that environment, but any info for it would be great as well.

Thanks!

Firefox use to keep me logged into Asana. But after deleting my browser cache a while back, it no longer does. Even though it still keeps me logged in to other sites I go to.

I have already tried to get help with this on Asana's help forum and a computer help group on FB. As well as from researching on google. I have tried everything they told me to do and it still isn't keeping me logged into Asana. I am completely baffled as to what it stopped keeping logged in. But I know it had to do with deleting my cache because it did it right after that when I tried to log back into Asana. It never kept me logged in again.

When I deleted my browser cache I made sure to not check the one that said it would log me out of website if I check it. I didn't delete that, I just deleted the other stuff that was in the gb range. So I don't know why every time I delete my cache it still logs me out of all website anyway even though I uncheck that.

Yesterday I reset firefox back to its default settings, but that didn't help either.

Any ideas what else I could try before I uninstall firefox and reinstall it. I have backed up my bookmarks, but the last time I had to import my bookmarks when I got a new computer it did not import them correctly and it made a mess out of my bookmarks and didn't even save my browser toolbar stuff. So reinstalling Firefox is my last option.

I'm getting Access denied Reference #18.6b01cb8.1700662622.22a58314 only on tesco.com since last nights firefox update.

All other sites are funtional (at least no others found yet). I have cleared cache and cookies but still getting the issue.

The site is up and accessible by ms edge.

I have run in troubleshooting mode and taken off any extensions, still no change.

Running windows 10 (latest updates)

Malwarebytes is reporting no issues.

So I just picked up a new laptop (ASUS Vivobook 16x), and everything is fresh on it. Additionally, this only affects some video content in Firefox, with Edge browser unaffected. In brief, what is happening is that within a couple hours of having the browser open, certain video content stops working, specifically Twitter/X videos just spin, YouTube previews stop working, and videos continually load. Netflix videos continue to work, but hover previews stop functioning. I even check the 'Stats for Nerds' on YT and it shows 0 KB network activity in Firefox.

I've tried every basic action I can think of:

• Turning off extensions (only use Ublock and Bitwarden)
• Browser Refresh (x3)
• Reverting from 120.1 to 120.0, and now 199.0.1
• Clearing the browser cache
• Reinstalling NVidia and Intel Drivers
• Running in Safe Mode

Only by doing a refresh or completely closing/opening the app gets videos to function again. This doesn't affect the old laptop or my desktop, which makes me think it's a rogue driver--but then why would Edge function without error over the same period of time?

Are there any settings to play with in the browser that can help diagnose?

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

The puzzle piece icon is not on the toolbar. Neither is it shown in the customize toolbar dialog. I have reset the toolbar to default, rebooted Windows 11 and removed & reinstalled Firefox 120.0.1 (64 bit). Those did not work. How can I restore the puzzle piece icon to the toolbar?

what triggers the captive portal login... ? It's a great feature on a phone!

I am experiencing it on Linux 6.1.0-13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.55-1 (2023-09-29) x86_64 GNU/Linux, Firefox 115.1 (esr?) to 120.0.

Firefox is talking out through a Comcast-supplied router to the outside world and the captive portal attempt is being sent to one of localhost's aliases.

The firewall was setup as ufw disable; ufw reset; ufw default deny incoming; ufw default allow outgoing; ufw enable. The local apache is reporting attempts to access localhost's /canonical.html every 3 seconds. 127.0.0.1 - - [22/Nov/2023:06:10:55 -0800] "GET /canonical.html HTTP/1.1" 301 582 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0" sc:80 127.0.0.1 - - [22/Nov/2023:06:10:58 -0800] "GET /canonical.html HTTP/1.1" 301 582 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0" sc:80 127.0.0.1 - - [22/Nov/2023:06:11:01 -0800] "GET /canonical.html HTTP/1.1" 301 582 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0" sc:80 127.0.0.1 - - [22/Nov/2023:06:11:04 -0800] "GET /canonical.html HTTP/1.1" 301 582 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0" sc:80 127.0.0.1 - - [22/Nov/2023:06:11:07 -0800] "GET /canonical.html HTTP/1.1" 301 582 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0" sc:80 127.0.0.1 - - [22/Nov/2023:06:11:10 -0800] "GET /canonical.html HTTP/1.1" 301 582 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0" sc:80 127.0.0.1 - - [22/Nov/2023:06:11:13 -0800] "GET /canonical.html HTTP/1.1" 301 582 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:120.0) Gecko/20100101 Firefox/120.0"

After years of shopping online with Tesco using Firefox suddenly I can no longer log in to Tesco.com. Just get 'Access Denied. You do not have permission to access------etc' I am sure that this happened after the last update of Firefox ! Tesco say its not their problem and the problem is with my Firefox browser. Please advise.

Starting on 12/1/23 Firefox browser on Windows PC is Not Responding while loading up bookmarks toolbar. Switching to "Never Show" is only way to load the browser. Trying to open or manage bookmarks freezes up the FF browser again.

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.
