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)

I'm having a pretty frustrating developer experience using Firefox to help develop an app that uses Server Sent Events. Now, I'm not sure if I'm the one at fault or if it's something to do with Firefox itself (most likely I'm missing a config option somewhere).

Anways, the issue I'm having is that I cannot seem to be able to see Server Sent Events in the network tab of dev tools. This is specifically what I'm looking for: https://firefox-source-docs.mozilla.org/devtools-user/network_monitor/inspecting_server-sent_events/index.html

I'm testing this functionality by going to https://sse.dev/testpage.html, opening my network tab. I can see the connection to the SSE endpoint however, all I see is "No headers for this request" or "No response data for this request". I know it's getting the data through the event source because I can do stuff with the data. I've also tested this in Edge and everything appears in their network tab as expected which, makes me feel like this is more of a browser-specific issue. Again, I feel like it's me missing a config somewhere or having a privacy setting set which is somehow messing with the event stream.

Any help is appreciated... I guess I got to use Edge for the time being 🤮

Hi All,

I would like the content area of my tabs moved up so that the box is filled with the actual tab color, without the white background, and also the text will be vertically centered. Right now, the text is dropping too close to the bottom of the tab.

Had this looking very nice in FF 88 with the same code, as you can see in the attached images, but it seems to render differently in FF 115 ESR and FF 125.

Below is some code I used to style the tabs, but the problem exists without this code as well.

I've also included some "tabs on bottom" code I'm using as well at the very bottom.

Would sure like to get those Classic Toolbar Buttons working again too (shown in the second image), but that will be a later request :)

Any help is appreciated.

Thanks!

Until today it worked fine. But now whenever I try to login to Xfinity I get You don't have permission to access "http://login.xfinity.com/login" on this server. It works fine on Chrome and Edge. I have disabled my add-ons. I have cleared cache, cookies, etc. I have rebooted. I have turned off firewall. I have checked my DNS. I have changed the DNS protection to OFF in Firefox. I have checked my proxy setting (I have no proxy). I have reinstalled Firefox. Etc. Etc. Nothing works. The fact that it works on Chrome and Edge, that it has worked everyday until today gets me confused. I also tried using my mobile phone as a hot spot to make sure it wasn't related to my Internet connection or IP address. Anyone have any ideas?

I'm stetting up a testing environment. It's a closed environment with no access to the Internet when it's in use.

The environment is launched from AWS and consists of an Ubuntu 18 desktop and a Ubuntu Server running Apache. The desktop is able to successfully load the website, but with a cert error that the certificate isn't trusted.

When the Ubuntu Desktop launches, it has a fresh install of Firefox, and therefore all the directories in the users home folder are not yet setup for Firefox, including the database where the root CAs are stored.

I'm am able to add the Root CA certificate into the Firefox cert database AFTER the machine fully boots and I run Firefox for the first time. I'm using the 'certutil' package to do this. After I load Firefox, then add the root CA certificate using certutil, I'm able to load the website without error.

I need to add this certificate to the database with the startup shell script for the machine.

Any help is greatly appreciated. Here's the commands I'm using:

1. copy the CA cert into firefox

export ffcerts=`ls /home/testuser/.mozilla/firefox/ | grep default-release` sudo certutil -A -n "testcert" -t "TC,," -i /home/testuser/certificates/testcertCA.pem -d sql:/home/testuser/.mozilla/firefox/$ffcerts

These commands work perfectly after Firefox is run for the first time. I've even tried adding 'Firefox' (with several different switches) into my startup script without success.

Hello. I love the feature. I didn't know it was a new feature because I started using Firefox around April. I saved my group tabs, very happy about it. Then I close and save it, then I opened it again, it was great!

I am a student, I use my group tab to add the tabs that have the resources that I need to, and would also like to study for more knowledge and for my next school year.

There was no problem at that whole time. In April 21, there was no problem until April 22, 23 no problem. But I forgot my charger at that time, because I was at my mothers house. Then I wait for weeks for my charger to come back, about 2 weeks for my laptop to revive there in my grandparent's house.

When I got my charger, and opened firefox. Wait, but at first when I opened firefox, it showed me that there is a new update, an update about tab groups that I already now. I looked at my group tabs, and they are not there anymore.

What should I do to get them back.

Dear all,

For some time now my Firefox browser is crashing while I use it. Then a loop starts where a window appear with buttons offering to Restart or Close Firefox but whichever I choose it takes several sets of open/crash to stabilize when in the end if offers to either open it again, or refresh Firefox. I don't wan to refresh because I have tens of tabs that I want to save. But I can't because OneTab, along with all other extensions, is being disabled after the restarts.

I have a crash ID of one of the latest occurrences of this phenomena: f6ef62ad-b072-46b8-8bc8-0d3ca0240708

Please advise!

Good day, everyone,

I've been using Firefox for several months since switching over when the migration to Manifest V3 in Chrome gained momentum. Initially, Firefox worked flawlessly, but over the past couple of months I've encountered a recurring issue where downloads often fail -- sometimes right at the start and other times midway through -- especially with larger files.

I've encountered this issue across multiple machines, and changing the destination drive where the files are saved hasn't made any difference. Interestingly, the same files download without any issues in Chrome, so I've ended up relying on Chrome exclusively for downloads.

Has anyone else experienced this issue?

Thanks in advance!

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

This problem exists ONLY on Firefox. I vary search engines, from DuckDuckGo to Presearch and Startpage depending on the search results I get.

For no apparent reason I will get a "suspended connection" message on Startpage while using the Firefox browser. I have included both the link and a screenshot of the problematic page. The page will open perfectly several times, and then suddenly, in the same session, if I open a new Startpage tab, this message will appear. While the suspended connection message is visible in Firefox / Startpage, I will try Startpage in Edge, Opera, Chrome and Midori, and they all open to the Starpage beautifully.

I am using the Firefox 125.0.3 browser, I have cleared caches and cookies, and run full malware scans, with zero negative results, and yet this problem persists. It is sporadic, and does not occur on a predictable basis. It occurs whether the Mozilla VPN is on or not, and switching from on to off or off to on changes nothing, even after refreshing the page.

I am assuming that this is a Firefox issue, as the problem does not occur on other browsers

I can easily switch browsers and / or search engines, but Firefox in conjuction with Startpage is my preferred combo. I just find it frustrating in that I cannot fix it myself.

So....Ehhhh...what's up doc?

Hello. I have a problem with turning off google safesearch. I'm 28 years old so it's not a problem with google acc. I have same firefox on pc and on laptop. On pc and on smarthphone it's easily turning off and if i'm using edge or chrome on laptop it's also turned off, but if i'm using firefox exactly on google it's always turned on no matter what i'm do. Just in case, if i'm using for example bing search in firefox it's also turned off, likely it's always turned when i'm using google with combination in firefox. Methods that I already tried: 1) Turned off in computer settings (not worked) 2) Reinstalled browser (not worked) 3) Checked in my wifi settings (not worked) 4) Updated everything (not worked) Waiting for your help.

I noticed my laptop was being slow, so I looked at the memory usage. Firefox was using a whopping 5GB of memory on Windows 11. I then looked at about:process and it reported that extensions were using 4GB. I disabled each of my extensions and it still said it was using 4GB of memory. I then uninstalled two of them and re-enabled some extensions and it dropped to 781MB. This is still to much in my opinion, and I want to know how to figure out which extension is being so wasteful. Even a technique on how to figure it out would be appreciated.

Hi.

Ever since I upgraded to version 123.0.1, I am constantly getting slowness on websites stuck in "Performing a TLS handshake..." Eventually the websites load, but it's frustrating. I have read about the various solutions and have tried the following: Disabled IPV6 Refreshed Firefox Reloaded Firefox Disabled and removed all extensions Restart in safe mode Create new profile

This was not happening in version 122 and before. Microsoft Edge does not have this problem, but I prefer to use Firefox. I am running Windows 11 Pro. Any ideas?

Thanks

Hello Firefox friends o/

Anyone knows how do I make https://yandex.com my default search engine? (in the top bar of the browser). I have attached a screenshot of my settings page. Please have a look at the suspicious lack of an "Add" button 🤔. Despite my efforts, the drop-down menu will not show the available options in the screenshot, you will have to take my word for it, the only available options in that menu are: Google, Bing, DuckDuckGo, eBay and Wikipedia (en).

P.S. The settings page in Firefox must change really often, as I seen so many people suggesting many outdated methods online.

Firefox takes a very long time to open the first tab. After it opens, subsequent tabs open relatively quickly. I've tried self help suggestions like clearing cookies, cache and history, updating, even removing home page content. Nothing helps. It's getting intolerable and I end up switching to other browsers rather than sit and wait. Starting to even dread using firefox. Running Sonama 14.3.1 on my iMac. What else can I do?

Until a week or two ago, Amazon Prime Video worked without a problem on my Firefox browser. Now I cannot get Prime Video to open any show, nor can I access previous episodes of any show. I tried removing all my add-ons, including all my ad blockers and making Prime Video an exception to the enhanced Firefox browser feature. Nothing worked. Can someone at Firefox fix this problem or tell me why it happened? I CAN use prime video without difficulty on Safari and Chrome.

This address uses a network port which is normally used for purposes other than Web browsing. Firefox has canceled the request for your protection.

Since this week I have been unable to access flightradar24 web site due to a problem with WebGL. It tells me that I need a compatible browser e.g. Firefox

I am running Linux Mint 21.3 Cinnamon on and I7 processor with a NVIDIA Corporation GK208B [GeForce GT 710] graphics card.

I have edited the about:config file as follows:

webgl.force_enabled TRUE

but noted a collection of failed messages as shown on the attached screen shot.

This web site is still accessible using chromium on the same computer, suggesting that there isn't a hardware problem.

Thanks

My system memory is reading at 57% right now in task manager, that the vast majority of that is being used by Firefox.

Why?

Normally, this would be called a flaw in the program, not the user, as all I have done in regards to settings is "keep tabs previous open when re-opening Firefox" and "Do not automatically update" because Firefox took it upon itself to not re-open my previous tabs on the last update.

Why is this program eating up all of that memory? I have "Firefox (15)" in Task manager under "Apps" and then 13 more instances of Firefox in "Backround Processes"

Wtf?
