Firefox Community Forum

I want to delete all my bookmarks at once -- I have nearly 1,500. I already asked this question and the response I got showed me how to do this by selecting each one at a time. I want to delete them all, AT ONCE!

Not selecting each one and holding down the CTRL key.

Btw, I already explained this ... so, is there a way. I've tried uninstalling and reinstalling and not keeping the former settings. But the stupid bookmarks keep coming back!

I'm on Developer Edition of Firefox. In previous versions of Firefox (Probably 132), I could share the window just fine, but since an update to either Teams or Firefox, it just results in a blank screen for viewers.

Just noticed the book mark banner under the URL line. It is taking up screen space. How do I get rid of it? How did it get displayed? Did some searching but no positive results. Not sure what to search for, definitely not book mark. If I delete the items from the banner are they deleted from my list of book marks. Some of these\book marks I do not remember saving? Where did they come from, some AI search or paid for vendor adds?

I prefer the tabs be below the bookmark bar, and successfully modified the CSS file to do this some time back. Now update 133 has once again pushed them up below the menu bar. What do I have to do to get them back where I want them this time? And why can't you just leave the tab location preference alone when doing updates?

My hotmail Email page stopped opening yesterday morning. I can open the Live.com page on my Android phone and Safari. I Don't like Safari, and I want to be on Firefox on my desktop.

I start firefox with following policies.json

{

   "policies": {
       "AppAutoUpdate": false,
       "BackgroundAppUpdate": false,
       "DisableAppUpdate": true,
       "DisableFeedbackCommands": true,
       "DisableFirefoxAccounts": true,
       "DisableFirefoxStudies": true,
       "DisablePocket": true,
       "DisableSystemAddonUpdate": true,
       "DisableTelemetry": true,
       "ExtensionUpdate": false
   }

}

But uncontrolled connections to the following addresses continue anyway:

• firefox.settings.services.mozilla.com
• aus5.mozilla.org

I may have missed something and you can tell me how I can control these connections inclusive. Because all other connections can be controlled by configs and policies. But not these and it raises big questions. It seems to me that the browser should allow to configure any network requests that aren't related to the user web browsing itself. If some connections cannot be controlled in any way then I can't call it anything other than either a bug or an attempt to monitor users as do in Google Chrome.

Having a problem with Firefox the last few weeks. I'm on 64-bit version 133. When I go to a web site I get the this message:

Hmm. We’re having trouble finding that site.

We can’t connect to the server at www.mozilla.org. 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)

If I reload the page from the 'Try Again' button or the reload icon in the top menu bar it will start to display. I usually have to reload multiple times for the page to start to load. Sometimes the page loads completely the first time, Sometimes it only loads partially (i.e. only text) or only part of the page loads correctly. I reload a few more times and the page finally loads completely. This makes it very difficult to browse almost any web page. I have Firefox on 3 computers (Windows 7 & 10) and have this problem on all three. I've visited web pages in Edge without problems. Any ideas? Thanks

I have used Firefox for years with no problems. The past month, however, I am encountering many problems with my often used web sites. What is going on? I make a purchase and cannot proceed. I have not added any new blockers or anything.

Running Firefox 133.0 on Ubuntu 20.04 desktop

Periodically, Firefox will freeze and send the message "Firefox must be restarted to continue". After restarting, Firefox takes a long time to recover. This morning, it took nearly 5 minutes to recover.

Firefox has become exceedingly slow. I have used Firefox for the most part going back to the beginning save a 2 year stint when Mozilla fell behind and did not update the product in the early years after ver 4. However, the slowness of Firefox is so bad now that I may have to find or use another browser! It is literally that bad! This problem is recent as in the last 45 days as far as my individual needs. I have already gone through the troubleshooting list and made the modifications. That seemed to work for a day or two but the slowness of Firefox is progressively getting worse with each passing day.

The speed is like 3 minutes to 10 minutes when just trying to open a known and commonly used bookmark. Checked against Edge which came with Win 11 and Edge loads within a second or two. So, the problem is not hardware or internet connection. I have one of the fastest speeds on the planet with a true fiber optic connection as I am close to the backbone location in my city. We are talking 2.1gig down and 820MB up. Tested against two different speed tests. The problem is with Firefox specific. Mozilla needs to address this issue as it seems to be an ongoing problem across several IOS platforms.

I have an mp4 (h264 AAC) video of 37MB which plays acceptably from my website in Safari, Chrome and Edge, but when played in Firefox (my default browser) the sound and picture synch is significantly seperated. When the video is compressed to 26MB it suffers some expected loss of sound quality but plays with near perfect lip synch. What is the issue with playback ?

Greetings Customer Service @ Mozilla While attempting to Turn on Mozilla Firefox Extension to Intensify the Detection Technologies through my Kaspersky Premium Software, I received the following error message:

After upgrading to FIREFOX 133 everything became a mess !!

Most pages will RANDOMLY not load and show “Security Connection Failed” message, indicating mostly one of this two errors Error code: PR_END_OF_FILE_ERROR Error code: SSL_ERROR_RX_RECORD_TOO_LONG Additionally and consistently trying to access Amazon makes it think I am a Robot, and shows a page with a Captcha but the images do not load (Image attached) 1Password fails in some pages (Such as CNN), the page shows an error message when userid & password are filled in, rendering it useless. NONE of this happen on previous versions of Firefox or on EDGE with the updated Norton360

I have tried: - Uninstalling, deleting all files and re-installing both Firefox and Norton 360 - Deleting the Firefox profile and starting from zero - Using Firefox without any Extension, it works for a while but then fails (memory overlay issue ?) - Loading a few extensions, again works for a while but then fails. If more trhan 4 or 5 extensions are loaded the problem is immediate (memory overlay issue ?) - Turning off Norton sometimes helps get to a page, and when turning it back on keeps working … Sometimes it does not - - Checked all indicaytions on support article https://support.mozilla.org/en-US/kb/secure-connection-failed-firefox-did-not-connect without any luck WHAT TO DO ?

Hi I am using firefox 132.0.2 (64-Bit) and experiencing the following issue: As long as a site is loading I can hardly scroll through the already loaded parts of the site by using two fingers on the touchapd. If I instead use the scrollbar I have no issues at all. But when using the touchpad, firefox is not responsive. The scrolling delays several seconds or does not even work at all. I am using PiHole and probably firefox still tries to load ads which are blocked by PiHole. But as I am not interested in ads, I would like to be able to scroll throught the page while firefox still tries to load the ads. That is perfectly possible without any delay by dragging the scrollbar. But it's not possible without lags using the touchpad. There is no issue using chrome or edge. BR Ralf

Hi,

I'm developing a website that needs to authenticate with an external endpoint. Once authenticated, the website receives a session cookie that it uses for subsequent API requests.

I've configured the CORS headers on both Apache and Nginx, but I can't get it to work in Firefox. Interestingly, the same setup works perfectly in Google Chrome.

Here's an example of the headers I receive using a curl call:

curl -X OPTIONS https://crlliria.moval.es/web/session/authenticate \ -H "Origin: https://gis.moval.es" \ -H "Access-Control-Request-Method: POST" -I -k

HTTP/1.1 204 No Content Server: nginx Date: Wed, 04 Dec 2024 10:23:24 GMT Connection: keep-alive Access-Control-Allow-Origin: https://gis.moval.es Access-Control-Allow-Credentials: true Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, DELETE Access-Control-Allow-Headers: DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range Access-Control-Max-Age: 1728000 Content-Type: text/plain; charset=utf-8 Content-Length: 0

Despite these headers appearing correct, Firefox throws the following error:

"Credential is not supported if the CORS header ‘Access-Control-Allow-Origin’ is ‘*’."

I know the Access-Control-Allow-Origin value is not * (it's set to https://gis.moval.es), so this message might not reflect the real issue. However, I can't figure out how to debug it further.

Questions:

Is there anything specific about Firefox's handling of CORS and credentials that might cause this issue? Are there tools or techniques I can use to diagnose the actual problem? Could there be a subtle discrepancy in the request or response that Firefox is stricter about compared to Chrome? Any help or suggestions would be greatly appreciated!

Thanks in advance.
