Unable to connect

Try Again

bold text When I try to go to my "FIREFOX" it answers me in French of course but here you don't accept to write me in French and so it's very difficult for me ... (could you help me for this of course ???) : "hmm this adress doesn' seem to be valid." Hum, cette adresse ne semble pas valide.

What must I do please ??? [edited from public] @orange.fr

Don't really have too much to say just needed help on understanding how these extension things work because I am not familiar with them at all I've just learned about him not even two weeks because I bought Chromebook and that's the first time I've ever seen them so I have no idea I don't even how to even activate them I read every single before downloading it but I'm still not understanding on how to even use it or even start to use it I have autism so I don't understand new things as well as others so I need extra help but by the time I know and know how to you know you all this I'd be able to help others after I learn how to you know do it because when I learn about anything new I get obsessed subs and I started learning everything about it

How can I tell Firefox to automatically set the volume to 2 or 3, and not play every video in every window full blast - which is maddening when I'm using Facebook and every video I click BLASTS! the sound WAY, WAY louder than any other devices I have outputting sound, such as Spotify music.

bold text Firefox has been my browser forever. When I tried to open it this morning I was invited to create a profile, so no profile, no Firefox..... I've never had to do this before and am reluctant because of the apparent threat of losing all my passwords and bookmarks. I'm 85 years of age so don't need this complication. Any help would be appreciated, complicated high tech answer will probably be beyond me. Brian.

Firefox 147.0.4 (aarch64) "hangs" for 30 seconds to 1 minute when I launch it on my MacBookPro (OS Tahoe.26.3). Itwon't open the simple web page I have Firefox set to open when it launches -- and I can't navigate to any other web pages. When I try to interrupt, I get an Apple spinning beach ball until finally, Firefox opens that first page.

After working with Apple tech support, I have disabled a number of content barrier Extensions in Firefox-- which Apple tech support felt might have been causing this behavior. Nothing works. And I hesitate to run Firefox without some of them.

I tried deleting my Firefox user profile from my computer, but all that did was prevent Firefox from opening at all.

How can I stop this?

[edited email from community support forum]

I get all other websites and I used to access couchmanagers.com on Firefox. But recently on about 90% of the clicks to this site I do NOT receive the "Current Auction" and "Chat" pages. What can I do to resolve this issue other than use another Browser. This site works fine on my Fire Tablet and everyone else computers and tablets.

Both the menu and the taskbar are not available since the latest update a few days ago. I've searched all options in Firefox settings with no luck in finding a solution. Help would be appreciated as this is extremely annoying and working around it wastes a whole lot of time.

Hover Tab in Style section in Elementor does not work in Mozilla Firefox! It works in Chrome and Opera, but I work in Mozilla Firefox. Many other users complain about this in Internet. When will you fix this bug?

Mint 147.0.4 64 bit I click on a pdf, it opens in qpdfview. It also saves in wherever my default save folder is. I later have to go remove all these junk PDFs from Downloads or wherever because I either didn't want them or saved them elsewhere.

Please stop "helping me". I do not want to be "helped". How can I stop this auto-save """feature"""?

I think this started back in 98.

Last night I decided I'd get rid of the little triangle on my id icon telling me my account is disconnected. I succeeded getting rid of it, but it screwed up my url for my homepage. Now when I try to set my homepage (c:/Users/mnose/Pictures/Pictures/Kidz/Photo-0002.jpg) I get this message: file:///c:/Users/mnose/Pictures/Pictures/Kidz/Photo-0002.jpg " The address wasn’t understood

Firefox doesn’t know how to open this address, because one of the following protocols (cfile) isn’t associated with any program or is not allowed in this context."

How do I get rid of this, and how do I set up my homepage? It's been set the same way for over 10 years until last night. It's very frustrating that there's no explanation.

Thank you for any relative responses and useful information.

After being able to view Netflix content on Firefox for, well, a long time, today I encountered audio with no video. Only a black screen. I contacted Netflix and they're telling me that Firefox needs updating - we tested Safari and it was able to play the entire content, video and audio. I checked Firefox and the info states the browser is up to date. I should add I'm on a Macbook Pro. The quality on Safari was not as good as Firefox has been so I would prefer not to have to use a second browser for one task. Can anyone provide some information on this situation?

my favorite browser firefox isnt enough help to keep my privacy secure (Its 100% confirmed)

I just learnt that my internet provider is blocking some domain like web.telegram.org which is very annoying. The solution i found on internet is vpn or tor browser.

Am i expecting something from firefox that it cant help me with?

A free vpn or tor browser like functionality?

I am so sorry to go away from it but look like if there is no way firefox can help me secure my privacy then i will have to.

Please try to be friend and help like a friend

On macOS, I set System Settings -> Desktop & Dock -> "Double-click a window's title bar" to "Fill".

In Firefox, double-clicking the window title bar does nothing. If I change the macOS setting to "Zoom", double-click works correctly in Firefox doing Zoom effect.

I confirmed that other applications respond correctly to the "Fill" setting.

Environment: - macOS version: 26.3 - Firefox version: 147.0.4 (aarch64)

I have changed nothing on my system. Yesterday my account showed all passwords and today all passwords are gone. The look of Mozilla has changed overnight. What happened? How can I restore it so I have access to my accounts?
