Firefox supportforum

A problem has arisen with firefox recently: when I tried to google something, or to open a website, I get the message: Oh no, the tab has gone down. I have reinstalled firefox but that didn't fix the problem.

I can access this website from other computers on my same network. But from my computer I get the following message

Access Denied You don't have permission to access "http://www.dsw.com/en/us/?" on this server.

Example video I have issues with: (https://www.youtube.com/watch?v=udXuzXhb9WY)

I can't watch youtube videos smoothly using the vp09 codec at 4k/1440p [Codec: vp09.00.51.08.01.01.01.01.00 (313) / opus (251)]. Constant buffering, lag, pausing of the video or just not playing at all keeps occurring with the video I put above for example, and other videos using the same codec.

My internet connection is very quick in fact, with getting ~90mbps upload/download. My computer specs are good, having an i7 12700kf and an rtx 3060 with 64gb of ram. All my drivers are on the latest version. The video I linked above plays for about 10 sec before not loading more of the video and just infinitely loading (The main issue that is causing this to happen is that when I open stats for nerds, the buffer health isn't being updated).

I tried various solutions online that I found on forums, such as forcing av1 encoding, which fixes the issue, however on that specific video I linked, keeps the quality at 1080p, which probably is a issue on youtubes part and the file format of the video. I tried many other fixes.

On microsoft edge, the video plays fine with no playback stutters or anything. I don't have any 3rd party extensions installed that may affect the video playback. I did a lot of things to eliminate as many variables as possible, but the issue persists. I did a full reinstall of the browser, reseting cookies and temp data and also trying the nightly version of firefox, but non of those fixes worked. Basically everything I thought of I did.

Like I mentioned before, this issue is NOT only for the youtube video I linked, but its for all videos using just the vp09 codec for the 4k/1080p quality. The only fix I did find for that video is actually while writing this, I left the tab open for the youtube video for a while then played it and it played smoothly with no interruptions and the buffer health was constantly being updated, but after refreshing the page, it was the same.

From what I can remember this issue hasn't been happening for the lifespan of my pc (less than 6 months), and I cannot remember when the issue started happening. It seems to be pretty recent (maybe 2-3 months if I were to guess). At first I started tolerating it and thought it was a small bug since it only happened on videos I played at 4k using the vp09 encoder, but now its really frustrating and makes it possible to watch most 4K content. Some videos I notice when it starts buffering, it resorts to an alternate av1 codec for 4k video, but its only for certain videos. Unfortunately I cannot back track and see what started this issue.

Here is some additional info:

   Windows 11
   NVIDIA Game ready driver version (555.85)
   No abnormal resource usage (Gpu, Cpu ram etc.)

Some of my add-on shortcuts have disappeared from the toolbar. I have tried all of the suggestions on your help site. If I go to the add-ons page, it says they are still there, but they don't show up in my browser.

Hi all,

I feel like this is a problem that must have been experienced and solved a thousand times... however I've tried all the suggested fixes I can find and the problem still persists.

When I load Firefox the pages take ages to load. It doesn't matter what the page is, it takes ages, except that about: pages load fine, no problem. When I say pages take ages to load, I mean that everything about the page takes ages, not only the next, not on the images and other content etc, everything. This only started happening today and I only created a new profile a month or so ago. I don't have many tabs open (maybe 20) of which 9 are pinned. I do have lots of extensions installed.

I've tried troubleshooting/safe mode, that makes no difference.

Private browsing and loading another profile are fine, they don't have this problem.

I've cleared all cache and data, cookies, etc, including startup cache.

I've deleted the content-prefs file, and removed places files.

I've tried disabling and enabling hardware acceleration.

I've tried disabling TRR.

Probably some other things too, but so far nothing has worked.

Suggestions please! :)

I've migrated to Firefox from Chrome and am getting everything as close as possible to my Chrome setup. This is a usability issue when I zoom on an image, that has a larger version. Chrome allows me to zoom to the full extent of the image, but Firefox screen shakes and doesn't allow the same detail. Screen recording and links below.

Hello.

Hey, I have been trying to figure out native Firefox solution for deleting firefox history after it's set number of days old. I did found solutions for older verions of firefox, and some addons, but nothing that's native or current.

I think having history is incredibly useful short term, lets say a week or some days, but I don't think I have ever had to dig trough my old history for something. Usually what you need is to find some page you closed recently or something. And while I would like to use deleting history after closing browser, it interferes with stuff that I'm logged in, reopening tabs after closing etc. And ofc, it actually deletes history which is useful short term.

This is both request for help and improvement. It would be nice to have option on "clear history when firefox closes" settings, to delete any selected data older than set number of days for instance. Or if there already isn't, something similar in about:config.

When I use 'Manage Bookmarks' and the Library to delete bookmarks and bookmark folders in addition to cleaning up duplicate bookmarks, the deleted folders and bookmarks automatically reappear in my Bookmark sidebar 1-2 hours later.

Initially, I had sync on but did not have Bookmarks checked for syncing. Deleted bookmarks and folders still reappeared. Then I turned off sync for this browser / machine. Deleted bookmarks and folders still reappeared.

I tried to see if there was a setting that enabled automatic restores of bookmark backups - but could not find one to turn off. I have tried refreshing the installation and starting again - using a one-time sync from another machine - but continue to be unable to permanently delete old / obsolete / duplicate bookmarks and folders.

I've also tried 2 Bookmark clean-up extensions. While I am able to delete duplicates and empty folders using these tools, 1-2 hours later they are back in the Bookmark sidebar.

Is there anyway to prevent the automatic restoration of the Bookmark Library?

Thank you

I'm on Win11. The recent releases of FF seem to have disabled my ability (while in FF) to bring my mouse to the lower area of my screen to have the Win11 lower task bar appear. In order to get here, I have to shrink FF via it's upper right hand shrink button, then in the Win11 home screen bring my mouse pointer down to the lower screen area to popup that task bar. Gemini suggests there's a compatibility setting related to issues with high res screens that FF has... but I can't find this switch/setting... maybe Gemini is hallucinating about this. (Curiously, Gemini insists that this is not a FF issue... despite the fact that it's the only app on my PC having this issue).

I have two problems:

1. After importing bookmarks from html file i can not see them under search bar. only i can see them when clicking on Show your bookmarks /Ctrl+Shift+O/. Bookmark toolbar is checked into Always show Where is the problem?

2. Blank shortcuts of some websites, i tried to fix it with all methods but failed like: Deleting the IconCache.db file then restart windows explorer Command prompt sfc /scannow Command prompt dism /online /cleanup-image /restorehealth Disable tablet mode and Widgets
