Firefox Support Forum

I use to be able to work on one app/window and hover over multiple tabs to obtain brief details on the browser (tabs) as it sits behind the app/window I'm currently working on. Since about a week ago, this feature has gone away. Now I have to be on the browser to be able to hover over the tabs to obtain the info I need on the tabs. I do this to compare the order # that displays on the tabs for what I use it for. How do I get this feature back. I want to be able to hover over tabs to view the small details even when not currently on the browser itself. Please help.

In the latest Windows update Microsoft Edge has taken over my browser. Mozilla is the default browser but if I double click to open a page it automatically loads Edge. Is there anything I can do?

Firefox V102.0.1 up to date. Right click to open link in new tab - new tab is displayed, link is shown in new address bar, nothing is displayed in the window. Thoughts?

I know this is likely to be a wont-fix resolution, but I'd like to confirm that.

So if a webserver has the extremely cautious content-security header:

content-security-policy default-src 'none';

Firefox will correctly not embed video from that same domain in web pages hosted by that domain.

Fine. Good. Totally right.

When the server sets the same flag on the media file itself, Firefox's media player won't play it in browser. Even if I directly open the URL as a user, signaling my user intent to accept the risks for the file, the default player Firefox creates uses the media file's content-security-policy FOR itself.

This means the media won't load, gives an unhelpful and incorrect error message about MIME types, and the only way to view it is to actively download it and view it in local media applications.

Now, given the risks of allowing exceptions in CSP, I will understand if the development team doesn't feel this is a safe change to make, and it's on website owners to prevent this, but I don't feel it's in keeping with the intent of CSP to prevent this case.

The problem comes up for two days after Windows crashes with a blue screen. After POR Windows recovers itself and now works, but FireFox and Thunderbird chrashes immediately after start. Do you have an idea, what can I do? FireFox crash ID: bp-c4fe47cd-45dc-4024-8cc1-4a2220231204

Thx, Flo

Hello, I cannot get videos to go into full screen in FF as they used to before latest update. Tested on various sites. There are no controls shown on YouTube unless i either hide the taskbar or scroll down both of which is a nuisance. On some sites the task bar stays at the bottom which it didn't used to do. link text

I tried to pay my Wells Fargo VISA bill online as I do every month. This morning it listed all my accounts correctly on the 'Accounts' screen, but when I clicked the options to transfer money, depending on the screen I was on, it gave a message "you do not have two accounts to transfer money from and to" (not the exact wording.)

I tried to use a different path to do the same thing, and on that screen it displayed the 'FROM' accounts correctly but the "TO" account area was blank.

I had to close Firefox, load Edge, and was able to transfer the money from the checking account and pay the VISA bill.

This has never happened before and I have done this transfer and pay operation every month for years. Something has changed in the browser and needs to be fixed.

I recently sent a lot of tabs from my phone to my computer. However, when I started Firefox on my computer, since Firefox tried to load the content of all sent tabs immediately instead loading them lazily (which I think probably should be the default behavior), it took a very long time for Firefox to display even the tab that was currently selected, and I therefore decided to kill Firefox and reopen it, in the hope that all new tabs would load lazily. Instead, when I reopened Firefox, none of the new tabs where there anymore; it was as if they had never been sent. I would like to get them back, but I have no idea how to. Does anyone know if that is possible and, if so, how?

Firefox seems to get stuck loading pages on the CSO Ireland website For example https://data.cso.ie/table/NIA13

It can be right intermittently but reoccurs again rapidly at random. Other browsers do not seem to have this issue.

Just opened up Fireox and everything has gone - all bookmarks and folders, toolbar with shortcuts, all of it. I am not a technical person. What do i do to get it all back? Thank you Harry

I have been receiving the following error code 'PR_END_OF_FILE_ERROR' on several website on my Firefox browser. Sometime, not all the time, I get the same error message while trying to use YouTube, while other times the site loads but says that I am offline and no internet connection. I have done all of the fixes that they say to use online and nothing seems to work. YouTube will occasionally work but none of the thumbnails will show up. Then there are other site that work fine.

Ok well i went to about config and tired off all the accessibility about the quick help bar and now my question is every time i try to go to google search and click on shopping no matter what item i am searching for I get a pop up at the the bottom i of the page every time i hit on shopping that say error update can not be added to this list or some thing like that. it was ok until the last update o of firefox and since i did that but am not sure why. doe not do it in Chrome just frefox. firefox is getting to the point b where i an thing king of leaving it.

I'm trying to import my passwords from chrome and cannot get it to work. I've set signon.management.page.fileImport.enabled to true and have tried both directly importing from chrome and creating a csv file and copying from that, but chrome won't copy passwords over directly and when using the csv file almost all the passwords are listed as missing fields and won't copy over. I'm unsure if there's something i'm missing in teh copy process or if i'm just stuck manually copying over passwords

Hello,

we have a BigBlueButton Server setup for our company. Until recently we used a TURN-Server to tunnel the UDP connections thrugh the firewall.

Due to performance issues we wanted to try and let the clients connect directly to the udp ports 16000 - 32000

In Chrome this works as expected.

In Firefox however when we set "media.peerconnection.turn.disable" to "true" FF does not find any WebRTC candidates. We checked the logs and it says there:

"relay only option is set without any TURN server configured" "relay/proxy only option results in ICE TCP being disabled"

But thats NOT true! The option "media.peerconnection.ice.relay_only" is definetly set to "false"

Tested on FF 115.5.0 ESR and 120.0.1

Does anyone have an idea whats happening here? Why doesnt FF even try to make a direct connection?

UPDATE: I just ran a test on our dev system. If we configure BBB so that it does not offer any TURN-servers, FF uses a direct connection. Sadly that is not possible, since we need the TURN server for external connections. When there are TURN-Candidates but TURN is disabled via FF config no connection is established at all. This definetly semms like a bug in FF, since the browser should still be able to simply try and connect directly.

Thank you for you support

My regular profile has deleted all saved history, tabs, bookmarks, etc. This happened before and seems related to having private browings open. and to an update in progress or recent.

Opend a private window. Then noticed regular FF wasn't opened. I opened the usual profile and all saved info is gone. Also, my stuff to be synced is way out of date so can't restore from there (I always had sync up to date). My "backup" can't be opened to restore.

Where do I find yesrterday's info? How do I restore my session, bookmarks, etc?

Last time, I tried to follow directions I found soemwhere but the instruction werent clear at all and had to restore from a disk image.

Why is there stsill the private window deleting regular window?

Dear Mozilla

I'm participating in a discussion group based on Wordpress (learning.martinus.dk), and when I try to sign in (learning.martinus.dk/wp-login.php), I get the error.

>> 406 Security Incident Detected Your request was blocked. The public IP address assigned to you, by your internet provider, might be suffering from poor reputation: Look up IP reputation here. <<

My IP adr. is 80.208.65.123 and it is NOT suffering from poor reputation -- and no problem when I sign in from e.g. Chrome!

So what can I do so I can use my favorite browser here too!?  ;o)

All the best, Henrik Denmark

So I just picked up a new laptop (ASUS Vivobook 16x), and everything is fresh on it. Additionally, this only affects some video content in Firefox, with Edge browser unaffected. In brief, what is happening is that within a couple hours of having the browser open, certain video content stops working, specifically Twitter/X videos just spin, YouTube previews stop working, and videos continually load. Netflix videos continue to work, but hover previews stop functioning. I even check the 'Stats for Nerds' on YT and it shows 0 KB network activity in Firefox.

I've tried every basic action I can think of:

• Turning off extensions (only use Ublock and Bitwarden)
• Browser Refresh (x3)
• Reverting from 120.1 to 120.0, and now 199.0.1
• Clearing the browser cache
• Reinstalling NVidia and Intel Drivers
• Running in Safe Mode

Only by doing a refresh or completely closing/opening the app gets videos to function again. This doesn't affect the old laptop or my desktop, which makes me think it's a rogue driver--but then why would Edge function without error over the same period of time?

Are there any settings to play with in the browser that can help diagnose?
