Hi,

My computer was wiped without a backup and my browser was thus deleted along with my logins and bookmark folders. I am now unable to log back in to that specific account and retrieve my bookmarks. I'd really appreciate help with this.

Thanks, Aman

I have been unable to connect to any website through firefox. Every other browser works. Can someone please help?

The error is:

Hmm. We’re having trouble finding that site.

We can’t connect to the server at www.google.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

Trying to recover from a hard drive crash. Had to buy a new desktop with Windows 11 Pro (looking to be a bad move). I downloaded/updated to Firefox 126.0 (maybe also looking to be a bad move).

Have my last "working" userChrome file (it took me weeks to perfect this to my needs).

I am looking for: C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\

but there is no "AppData" folder. And there is no existing userChrome.css file, anywhere!

Is the functionality I am looking for a thing of the past?

Is Firefox not completely supported by Windows 11?

If so, what is the last version of Firefox that will still support userChrome.css?

my best search site is firefox used it long time started as month ago will not scan says address looks wrong or suspicious and does nothing can you help, memory cleared many times nothing helps it seems to affect google also

I am traveling in Mexico, connected to a network. I dont speak spanish but my laptop/firefox and at&t mobile phone now do - ONLY Spanish. How do I reset so doesn't automatically pull every website up in spanish?

Hello! I accidentally clicked to restore default setting in the customize toolbar menu, and now all of my tab/address bar/bookmark bar setting and locations are different and I don't like it at all. Previously, the address bar was above the tabs and the full length of the window. Now the tabs are at the top and the address bar is on the same bar as the bookmarks I have saved to the bookmark bar. The address bar goes full length if I remove the bookmark bar but I want to have both on the screen at the same time, on their own bar, as I did before. I have looked through the all of the settings and customize options, and can't find anything that will move my address bar to the top above the tabs, or a way to keep the address bar and bookmark bar open and available separately. Help! Thanks. :)

Since the past 2 days whenever I try to upload a document on any website my FireFox crashes and stops responding. Upon Further investigation it turns out this is only happening on the Downloads folder. I havent changed anything in my computer. No new software, No windows updates. It just randomly stopped working last night .

I have done every single thing including reinstalling Firefox. The Youtube videos will not buffer in my Firefox browser in ANY mode, safe, troubleshooting, etc. I got it to start after reinstalling then about a minute into the video it started buffering again. I can watch vids in ANY other browser, and am connected by ethernet to my router.

I know it takes just two mouse clicks to open the About dialog, but I'd like to bookmark it so when I check my daily bookmarks by right-clicking a folder and clicking "Open All Bookmarks", it would be displayed. This would be a convenient, albeit forceful, way to keep Firefox up-to-date. The About dialog isn't modal, so that shouldn't be an issue.

I have been using Firefox for quite a while. Recently, I cannot use Firefox for Youtube TV. The audio plays, but the first screen is frozen, and does not play the live video. I have toggled the hardware acceleration without resolution.

Any ideas?

Thank you

Everytime I load Firefox the bookmarks sidebar is not shown.

Navigating thus View => Sidebar => Bookmarks I can bring it up. It will stay visible for the whole of my browser session. However, after I've closed this session and started another. the bookmark sidebar is missing again.

How can I make the bookmarks sidr be available all the time?
