Whenever I open up PDFs within the Firefox browser, they have a black background and the text and images do not appear. I can copy the text and images out of the pdf and into a word document and it works out fine. Also opening it up on other applications works out fine. Attached is what happens when I open up a known working pdf in Firefox. The browser version is the current version, 135.0.

After entering verification code from email i receive an error every time i try to login into this account on my PC, i fully cleared browser data several times but it didn't help

Hello,

For a few days now I've been unable to use Google tools via Firefox (I can't tell if this is due to an update or not).

As soon as a document (usually an editable or navigable area) is opened on the page, it appears completely black. Interactions work correctly at first glance (it's possible to click, write, interact with content that isn't displayed. The problem seems to be purely visual.

I've encountered the problem in all Google Sheet or Docs documents (including when I'm making a new one) and on Google Maps, regardless of location (in the case of Google maps, a notable point is that the map is displayed and then turns black after one or two seconds).

I don't have this problem on another browser, I have it in PM.

Do you have any ideas on how to find the cause and fix the problem?

Have a nice day!

When I was previously using Firefox in Kubuntu 22.04, if I downloaded something I could go to the Downloads icon and click on the download and it would open in the desired application. After a failed upgrade to 24.04 I had to do a reinstall and now in Kubuntu 24.04, if I click on a downloaded file it will always bring up a window with "Open the file link with okular?" and the buttons Cancel and Open Link below. How do I go back to the previous way of it working?

Just recently I have found that certain sites are unavailable to me using Firefox but I can access them using Edge or Chrome. One particular one is Squarespace.

Is there anything known - how should I tackle this?

No idea if this is the right topic or not but I've been dealing with this frustrating issue where with some websites it just loads a blank white screen. I've tried every fix I could that I've seen on forums like this as well as on Reddit and nothing I've tried has fixed it. From launching in Safe Mode or changing things in about:config. Before finishing this post I tried launching in safe mode, so my add-ons and plugins are disabled and it still persists with websites loading in these blank white screens. I never had this issue at first and I'm sure it started to happen after an automatic update a while back.

I need this issue sorted out so I can look and compare items from shops but most of the time a website that works and I look at it elsewhere I'm dealing with this issue. No issue looking at stuff on the internet on my phone, though I do use safari instead on my phone.

If I go on any website using OSM data (including OpenStreetMap itself) on Firefox logged into my account, I experience a lot of slowdown. This doesn't happen when I use incognito mode or when I use another browser, so I'm pretty sure there's some kind of cache or something that's connected to my Mozilla account that slows down OSM massively. I've tried clearing all cache and all cookies. I've even refreshed Firefox using the installer and it's still slow. I don't want to bother with deleting my account and creating a new one. What should I do to try and return back to normalcy on OSM?

On Feb 13th I went to my website at MyHeritage.com, to which I'm always logged in, to find that a few seconds after it loads it becomes all greyed out and I can't access anything. I had been on the site a couple of weeks earlier with no problems.

I removed the "Enhanced Tracking Protection" and I turned off AdBlocker for the site but the problem persists. I have logged out and then logged in - same problem. I turned off my computer and restarted it - same problem.

When I went to log in to my account at MyHeritage using my Chrome browser I encountered the same problem of a greyed out page BUT there was a banner stating something about cookies and when I clicked the "I understand" button the greyed out page cleared and I was able to access my account.

However, Firefox is my default browser and I want to be able to access this page using Firefox. It seems to have something to do with cookies.

new install of firefox won't load accounts.firefox.com

other browsers on the computer load it fine

I've imported bookmarks and passwords and stuff, and since refreshed firefox but can't find a way to fully restore it to initial settings, even uninstall and reinstall won't do it

With Firefox 135.0 i cant reach google.com but google.se i can.

I make daily images of C: and today i managed to go back one day to 2025-02-06 but accidentally chooses 2025-01-06 and with the older version of firefox i could reach google.com

I have tried to delete cookies. DNS over HTTPS off. No proxy in connection. Add-ons off but to no avail.

I've never had sponsored shortcuts and suddenly today I've got them. I've attempted the disable the "sponsored shortcuts" on my desktop however its greyed out.

Starting state - Shortcuts selected, sponsored selected and grey Procedure: 1.) Deselect shortcuts, select shortcuts, sponsored becomes cyan 2.) Click sponsored, it becomes grey again 3.) Deselect shortcuts, select shortcuts, sponsored becomes cyan (again) 4.) Click sponsored, it appears deselected 5.) Hit refresh and it returns to starting state

I do not edit my GPO or registry, settings are not controlled by an organization, I am not confusing sponsored shortcuts with pinned search engines.

Hello! from this morning and alongside a new Firefox update i've been having graphical artifacts on Youtube/Facebook/Netflix. I've followed all the standard steps.

Disabled Hardware Acceleration. Updated Video Drives. Run FF in Safe Mode without plugins. Disabled Router level VPN and Ghostery.

Any ideas?

I'm running FF135.0 Geforce 572.16 Drives (30th Jan) 3070TI. Windows 10 Pro 22H2.
