The extension developers claim that the issue is with Firefox and deny no fault whatsoever.

I don't know what's happening but since a couple of days, let's say Wednesday 13th November, my firefox got incredibly slow: everytime I insert a url or a link in the address bar and press enter it takes a lot of time to completely load the website.

I tried to use Edge instead, and Edge is working flawlessly, while Firefox is not.

I also did a fresh install, wiping the %APPDATA% folders too, but nothing changes.

Setup:

• Firefox version 132.0.2
• on Windows 10
• Firefox and Windows are 64 bit

Hi

Reinstalled Win 10 pro on my i7 4th gen 16gb RAM 250 SSD copied firefox profile folder which brings back all my windows tabs bookmarks etc

I now get tabs crashing constantly

Before the reformat I used Norton 360 at mostley default settings for over 6 months with no problems,

tried turning things off in Norton

Norton 360 is reinstalled: browser extensions, password manager, norton homepage, norton safeweb, norton safesearch are all not installed Browser and browser data protection is on, VPN is off turned off auto protect and smartfirewall

use to use adblockplus and privacy badger firefox add ons with no problem these are now off

Ive refreshed startup and cleared startup cache

maybe when I copied the profile across it missed some files however I did zip the old profile folder and copied its a big file 690MB unzipped

not sure what to do now

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.

1. some webpages extremely slow loading while others are fine. All load fine on Chrome. Why? Particularly true with https://www.tab.com.au/ that I use 2-3 times a week. In Chrome it's immediate connect.

2. cannot sign in to my members account on (eg) Choice but easy on Chrome. Why?

Love Firefox when it works but I'm getting so frustrated. Seriously considering going back to Chrome - reluctantly.

Also so many website/page freezes & non responses over last ~3 months. Grrrr

Wikipedia render Thai fonts correctly. But it seems to render Latin texts and numbers in "TH Charm of AU" font for Thai articles, which I did not set anywhere in the browser (and my operating system). Ticking "Allow pages to choose their own fonts, instead of your selections above" does not fix it either. But it renders fonts correctly in English version of the same article. (See the attached images).

Any ways to fix this?

Thanks in advance.

Been using Firefox since the 90s and been on Mac since 2000s. This problem has been happening for about a year, throughout three macbooks (my old one, a temp one, and my new one) and multiple Firefox updates. I'm always updated and always clear cookies daily.

The failure to move bookmarks I can overcome by rebooting Firefox with a Forced Quit. If I only have to do this every few weeks, then no biggy reinserting all my passwords for all the different sites I use (and no, I don't want to use password managers, I don't trust them)

Today it happened within hours of Force Quitting Firefox, this is too much!!!

The only reason I didn't report this problem earlier is I simply expected an eventual newer version of Firefox to fix this bug.

Firefox 133.0

Normal behaviour: click-drag bookmark within bookmark menu pull-down to position where I want bookmark Failure behaviour: click-drag fails to move bookmark, until I reboot Firefox, then it works again

I have tried multiple media players and I have the same issue with all of them

Whilst playing a downloaded video - as soon as I open a new window to perform a search - the video stutters and the playback is slurred for a couple up to several seconds

Started on VLC so I tried PotPlayer instead same issue

Thanks in advance

I can't print my gmails any longer after firefox update:

error: Grrr! A popup blocker may be preventing the application from opening the page. If you have a popup blocker, try disabling it to open the window.

There are reports of conflicts between Firefox performance and Sequoia, how to resolve it? I would like to update from my current MacOS and I‘m not willing to give up Firefox as my primary browser. Could I get advice when it‘s save to update? Best regards RB

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have macOS.

I have Firefox version 136.0.2. I think it was quite recently updated. The right click menu is broken. The choice list is much longer, and the choices "open link in new tab" and "copy link" (ones I tried) do not work. This only started happening this morning. Right click works fine in Chrome. Screenshot included.

Attachment is a screenshot shows task manger shows there are 64 open files open, when I have only 4 windows open. What would causing this?

Over night Firefox closes and close all my open windows. I need the windows remain open.

Thank you for sharing your wisdom with me.

This is a problem I only started experiencing yesterday, but if I try to upload an image to a website (such as social media), and I double-click a shortcut for a folder, it attempts to upload the shortcut as the selected file, instead of opening the folder.

This is only a problem with firefox, as I tried doing this in another browser and I was able to open it as a folder normally. Any ideas on what could be causing this or how to fix this?

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.
