I went to my favorite web site this morning (dpreview/forums) and when it displayed I must have accidentally clicked some Firefox thing because the page was then overlaid with a thin orange highlight with the word PICK on it. I tried moving the cursor off the page but it only changed which segments of the page were highlighted. So I clicked and the page was replaced by just the menu section of the page, apparently that was what was highlighted when I clicked.

Now, no matter what I do, when I try to go to that url only the menu is displayed, the normal list of forums is missing. I've restarted FF. I've rebooted. I've cleared cookies and cache. I've refreshed the page. Nothing helps. Other web sites are fine. I can't imagine what this is for. A diagnostic tool or accessibility thing perhaps.

Please help. I'm running latest FF on latest Win 11.

After the Dec 10 update to 133.0.3 (aarch64) on my MacBook Air macOS 15.1.1, all of the menu keystroke options are greyed out. Also, in Settings, Firefox is selected as the default browser, but the option is greyed out so that it is not possible to change. I've disabled all add-ons except my password program, tried troubleshooting mode, and restarted.

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

Firefox recently sent out its monthly newsletter (Oct '25) with all sorts of options that can be enabled on Firefox. I'm a computer illiterate & foolishly chose some of the options -- don't remember which nor know how to discover them.

Now javascript is no longer enabled on my MacBook Air (macOs Big Sur 11.7.10). I cannot access my protonmail account and many many other sites.

I've gone cross-eyed accessing "fixes" that are labelled "only for advanced users" & am bright enough to not even try.

Is there a simple fix (short of wiping my computer -- with data going back 11 years) that even I can do?

If you have "fixing your firefox for Dummies" then please email me with a solution. [edited email from public community support forum]

Good evening Mozilla,

Well I am facing an issue, no sound coming from any website like netflix or youtube or prime from mozilla browser.

Could you please fix it for me.

Regards

How can I restore a previous theme? I had a "colorfore" theme that Mozilla offered a few years ago set up in Firefox. It was perfect! I could see everything clearly with my aging eyesight.Then one of my synced computers needed a new Linux OS installation so I signed out of sync on that machine. Installed the new OS. When I started Firefox the first time I signed into sync. I got my history, bookmarks and bookmark bar, but no custom colors. Now my computer at work has its colors reset to the out of box colors too. I have lost the colorfore colors I have been using for several years now. How can I get the colorfore colors back? Thank you for your attention in this matter. I love Firefox, use it exclusively and contribute to Mozilla. Gregg Scholfield
