I love Firefox, I use it on all my devices. And daily I access facebook.com on this browser, it's been working flawlessly - until yesterday. Yesterday, using Firefox (ver 130.0.1) on my Windows 10 PC, I tried accessing a FB page which I visit sometimes: https://www.facebook.com/OpenOscillator

Rather than reaching that page, I got a white screen with this error message: "Sorry, something went wrong." And since then, even visiting the Facebook home page (or any other FB page) has the same error message.

Today I tried the same thing on my Mac (OS 14.3), using Firefox and logging into facebook.com, which worked as usual. But when I went to https://www.facebook.com/OpenOscillator, I got the same error message: "Sorry, something went wrong." And as happened on my PC, now on my Mac I can't access any FB page on Firefox.

And just to mention, I've rebooted both the PC and the Mac, yet this problem persists on both devices.

Trying this same exercise on Edge on my PC does not have this problem. Nor does it happen when doing this on Safari on my Mac.

So, this problem has only been happening on Firefox. I can no longer access facebook.com with Firefox. Do you guys have any ideas how to solve this?

Helpful to know: Do you have the same outcome if you visit this FB page: https://www.facebook.com/OpenOscillator

Thanks for your assistance! Steven

duplicate of /questions/1466153 thread

I thought I had solved this by adding the website to the "safe" list - I really cannot say how frustrating this is if I am being locked out of even safe sites. - This is a browser issue (I'm not that naive).

There is no real response from Moacilla(Firefox) here apart from throwing the Rulebbok at me and saying "Read!". I can only do so much Tune ups" and shut downs and ensure drives are functional. Please advise on the Browser Cache situation, rspecially as BBC iPlayer is added to the "Safe List" and yet still throws up the 400 Bad Gateway error message - an early reply would be useful.

I used this a lot, but now cannot find it on any toolbar. I've added no software or made any changes in the interim. I was hospitalized from 1/10 to 1/31, and didn't use my computer in that period. I updated Firefox, and still can't find the control.

I have been using container tabs to juggle my corporate and personal github accounts. Until very recently, clicking a link from another app (email, etc) would start to open a new tab and then pop up a dialog asking me to confirm which container to use (see first attachment).

Unfortunately, now when I click on links it just loads straight to my "OSS github" container, which naturally produces a 404 error because my personal github account doesn't have access to the corporate repo (see second attachment).

At first, I thought I had accidentally clicked the "remember my decision" box. But the confirmation dialog still works if I open a new tab and paste the link in the address bar. It just doesn't work when other apps try to open a link in Firefox.

Is the new behavior intentional? Or did something accidentally break?

I am using VPN and have excluded FF using split tunnel, so I enabled Secure DNS in FF with Cloudflare. When I first launch FF, I get a blank page and nothing in the address bar. After that, I can open all webpages just fine. It's only that first page right when launching FF that doesn't work properly.

I have Firefox installed on multiple devices and most/all of them don't keep sessions or browsing history

I noticed that these files are updated while browser is open and get deleted once browser is closed:

  • sessionstore-backups/recovery.baklz4
  • sessionstore-backups/recovery.jsonlz4

No other files are related to sessions

I have "Open previous windows and tabs" checked

Installations:

  • Windows 10
  • Debian 12
  • Debian 13 (Firefox 148.0 Snap)

On Firefox for Android, this issue doesn't happen, I can even see the whole browsing history including history lost on PC installations

I've noticed recently that some Unicode characters are not rendering properly on some websites. Specifically the Unicode characters for Mathematical Bold Capitals, though there may be others. I've noticed this issue on Twitch and GitHub. Screenshots for the repository sainnhe/everforest are attached along with the Inspector. Notice the characters do not appear properly on the webpage but are rendered just fine in Inspector. I also attached the screenshot for Unicode Mathematical Bold Capital E.

I am running Firefox version 132.0 on macOS Sequoia 15.0.1. The problem remains in Troubleshoot Mode. The problem does not appear in Chrome or Safari. The problem does not appear on my iPhone or Android tablet.

In posts with similar issues I've seen the suggestion to toggle "Allow pages to choose their own fonts", the issue does not respond to changing this setting (it is on in all the screenshots).
