Firefox Support Forum

I have just upgraded the OS on Mac Mini with the M1 chip to Sonoma (14.5) I am running Firefox 126.0.

Now it seems that I have more than one problem since the upgrade. The browsing history in my sidebar is not current. It is running about a day behind.

I reported earlier that the type on my LinkedIn is only out 7 pt when my settings have the minimum size at 14 pt.

Somebody please help. I'm afraid to do a refresh because I don't know what it will do to my banking settings.

Just today, I can no longer access the Amazon website. The pages load halfway and then it just churns/spins and never completes loading the page. So far I've discovered no other websites that have the same problem.

I am able to access the Amazon website on three other browsers - Edge, Brave and DuckDuckGo - with no problems and normal loading speed. I don't use Chrome, so I can't speak to that.

I've tried clearing the cache and that did not help. I had a Firefox update installed a couple of days ago. Don't know how long it had been sitting there, as Firefox is almost always open and doesn't have the opportunity to update until I close everything and restart my computer, which I did a couple of days ago.

Windows 10 on a Dell pc/laptop. Firefox Version 126.0 (64-bit).

Any ideas on how to fix?

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.

Hello! I installed Firefox about a year ago, and for the entire duration it seems about 60% of the time the default fonts on various websites look weird (bold?). I have tried uninstalling/reinstalling Firefox, clearing the cache, etc. See attached images for examples. Help!

Sometimes drag functionality stops working. I can't grab a tab to move it to another position or to a new window. (Holding left click on the tab and moving the cursor does nothing). Also, re-merging the tab with another firefox window stops working. (Dragging a tab to a firefox window from another firefox window doesn't merge them. It does nothing) I can right click on the tab and select Move to move it to a new window but dragging stops working. I have to close Firefox and start it again (sometimes twice), then dragging starts working again. This happens multiple times a day. I am on Linux Mint and the version is 126.0 (64-bit). This problematic behavior has only recently began.

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.)

CloudFlare is not allowing me to use Firefox for a host of sites that I routinely use, such as my bank, Credit Union 1. I have tried repeatedly and will not recognize my computer so I have to use Chrome to get through.

They are locking me out as a spammer because I am using Firefox. Whats up with that?????

Despite changing the settings and saving them to the cloud. Firefox keeps resetting to Canada as my default country. How can I change this since I live in the UK. I do not use a VPN for Canada.

Been searching. Updated firefox and lost passwords (across MacBook and iMac Firefox versions) so googled, went looking for logins.json etc files. No sign of them, and no firefox folder in applicationsupport/library on my Mac. Showing hidden files. About:profiles shows only one profile. No idea how I can restore things. Time Machine backup on desktop iMac has no firefox profile files. Where is the data please? Etc etc :O)

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.

Since 2 weeks, I have been facing a UI error in the address bar. Whenever I select it to type something, the bar and search suggestions jump up off-screen. Pic attached.

Whenever I try to log into my online banking all I get is a white screen, nothing whatsoever.

I can log in just fine using the dreaded Microsoft Edge or Chrome but firefox will not work.

Now, I do know that I have actually logged in with firefox because if I come back to the page 10 minute later I get a banking message saying that as I haven't done anything for 10 minutes it has now logged me out!

I have cleared cache & cookies, I've started in safe mode and looked at the threads in the forum but nothing helps.

This is happening on all instances of firefox that I have, work, home, laptop.

please help

thanks

I just updated Firefox & added recommended things. I went to "https://www.cranecu.org/" As soon as I hit the LogIn button I got an "Error 404" message. However, I called the office help & they suggested I try another browser. I switched to Safari the button works just fine. Any Suggestions? I am not the sharpest tack in the box when it comes to computers so please be simple. Thank You
