Firefox Community Forum

On our web site we have a page that includes mp3 files, which play okay on Firefox; but on another page on the site with mp3 files, Firefox (including different versions on different computers) produces the error message, No video with supported format and MIME type found." FWIW, other browsers like Safari (Mac), Chrome (Mac and Win), and Edge (Win) all play the problematic files without a hitch.

Is there a fix for this problem that can be attempted by the non-tech types?

I got a new Macbook Pro recently and set it up by basically copying my iMac onto it. All works great. Except that the MBP doesn't show up with it's synced open taps on my iMac or my iphone. The iMac doens't show up on the MBP either.

Have I maybe copied some setting that makes the two machines (iMAc and MBP) thinkt they're one and the same? How can I "separate" the devices so that they show up in each other's Synced Tabs lists, respectively?

Help! Since the last upgrade I can't log in to several of my sites- the sign-in page refuses to load (e.g. https://ottawacitizen.com/) and several site Captchas refuse to accept any answer. In all cases, Safari has no problem when I switch to it (I hate their interface compared to Firefox). I'm on macOS 12.6.6 desktop.

Dont know how it happen but "https://ww25.waterdropswiter.xyz" has taken over comes up everywhere when tying in web adress and has give it self free access to everything

When I start typing 'subscr..' into the URL bar, I'd like it to autocomplete / select 'Subscriptions' from my bookmarks.

However, instead the default item is a Google search for 'subscr' as shown in the image.

Is there a way to skip this and make it select the top suggestion instead, much like Chrome does? (I've jumped ship from Chrome)

Google search no longer works on Firefox. Other browsers have no problems. Changing the default search engine on Firefox works (eg Bing), BUT. It can now find Google Maps, but Google Maps cannot find a location, because it uses a Google search. I tried the fix in about:config, but it had no effect.

i stumbled on site actblue is sharing with 2 cross site cookies with websites i never allowed. i never look at the details because mac firefox "Standard" text implies never can have cross site tracking. (i find no exceptions in my profile and i would have never knowingly allowed any cross site tracking.) how can i quickly see which sites in my firefox currently allow cross site tracking?

Standard Balanced for protection and performance. Pages will load normally. Firefox blocks the following: Social media trackers Cross-site cookies in all windows Tracking content in Private Windows Cryptominers Fingerprinters Includes Total Cookie Protection, our most powerful privacy feature ever Total Cookie Protection contains cookies to the site you’re on, so trackers can’t use them to follow you between sites.

thank you!

I use firefox on mac as well as on my iphone. I am attempting to update the saved address and credit cards on my profile. Using the web browser, I can navigate to settings and see my saved passwords but there is no option to view or edit my saved addresses. The only result shown when I search for addresses is the sync option to change if I am syncing that across my devices but not to change or view it or my saved credit cards for that matter. I am currently on 128.0.3 on my computer. I also have tried to update the address and credit cards on my phone app where I am able to access the saved information and at least see it but there is no option to edit. Tapping or swiping on the addresses do nothing. Pressing and holding will highlight the addresses but nothing will happen. Please help me use this product. I have been on firefox for 10+ years and have enjoyed the offerings but am incredibly frustrated not being able to see or edit my information. Thank you

dom.push.userAgentID 9222cf81d084464d9818890b2d9facde is what i get when i select show only modified preferences. Also my About This Mac says my OS is 13.6.7 and as you can see listed below it says 10.15. something strange is going on and has been for a long time. I deserve my privacy just like everyone else! I have no idea what this could be. Any help would be great. Thanks, Gino

Hi, I get a message "No video with supported format and MIME type" when I try to watch movies on my website : https://www.spiriferminerals.com/product,25270,produkt.html The same movie works on Chrome but not on Firefox. Can you help ? Thanks ! Joanna

When trying to download a Firefox update or a PDF file, instead of displaying a popup for specifying a download location only a small menu appears and the screen locks up. If I'm lucky I can unlock Firefox using the ESC key; otherwise I have to do a Force Quit. I've included screenshots showing what I'm seeing along with what I should see.

Dear Firefox, I want to install any VPN app to access my Bank account, but my phone number is not available because I am outside the Americas. Can you let me know how can I install and use any VPN program you provide? Thank you so much for your help!

I am trying to upgrade firefox to the latest version on my intel imac. The os is Sonoma 14.5 I download the .dmg file and when I try to mount the diskimage it gives me this error "Operation Not Permitted" I tried to verify the .dmg file using the mac disk utility program. It won't do it. It just gives me the same "Operation not Permitted" error. I tried verifying another .dmg file in the same directory (downloads) Disk Utilities performs the operation just fine on that .dmg .

?????

I'd appreciate any help. Thanks.
