I am suddenly getting the following error message: "We recommend you use a different browser or disable the “EasyList Cookie” filter from your “Content Filtering” settings (found under “Settings” -> “Shields” in the Brave Browser)." Firefox is now unusable. I have searched "Settings" and can find nothing about "Content Filtering," "Shields," or "Brave Browser." Can you tell me what is going on here?

My laptop died. I purchased a new one and pulled the SSD drive from the dead laptop and hooked it up to the new laptop with a SATA to USB cable and have access to the drive now. How do I pull all the information that was in Firefox (bookmarks, open tabs when laptop died, etc.) from the old drive to the new laptop?

cAPTCHA is recent problem in Firefox browser ... never before was it a problem. cAPTCHA keeps asking to choose an image but keeps on never verified ... I had to get Chrome browser to finally log in to a site I wanted.

When using FF connected to local host by HTTP and web-socket connections, am experiencing an issue when WIFI is newly disconnected or connected.

When the page is first loaded (whether WIFI is connected or not), both HTTP and web sockets work as expected. When the WIFI connection is then changed from its current state, initially no errors are thrown. However, although the very next web-socket request from the browser to the local server reaches the server, the response is rejected by the browser and the socket is closed, firing the onerror and onclose events of the socket. The HTTP requests are still processed in both directions (can fetch without issue) and can request another new web socket connection without error. The error thrown is `The connection to ws://127.0.0.1/34215... was interrupted while the page was loading.`

This takes place when the port is anything other than 8000; all works as expected when the port number is 8000. The local server was set to choose a random unused port number to avoid conflicts with any other running applications.

If the socket would throw an error before sending the new request, then it would be less of an issue; but, when that request was to save data passed in the XOR frame, the browser has no way of knowing whether or not it was successful because it rejects the response, such that the UI and database could become out-of-sync.

This is run under a separate profile that is set to work offline (removing offline does not resolve this). Are there any `about:config settings` that might stop the browser from rejecting the responses? Perhaps it is a security measure.

This was tested on chrome-based browsers and WIFI can be connected and disconnected multiple times and the web socket is never closed regardless of the port number.

Thank you for any guidance you may be able to provide.

I had several windows open each with different tabs in them.

I shut down them down and switched off my Mac.

On restarting my Mac, one of the windows had disappeared from the restore session. I've checked my History but the tabs don't appear there.

I'm using the latest version of FF on a Mac Air M2

Please advise.

Hello fellow Firefox users, I sadly cannot use my Firefox (120.0.1, 64 bits, Windows 10) anymore as it is too slow to show a webpage... It's so slow, that I initially thought that I have no internet connexion at all on Firefox.

Can anyone help me figuring why my Firefox profile is so slow ?

Long story short:

- Until 2023-12-05, my Firefox was working normally.

 My parameters were "No HTTPS everywhere" and "No DNS over HTTPS (DoH)".

- On 2023-12-05, I was connected to an entreprise DNS (Mangling DNS).

 I cannot acces some website because of their local policy, so I changed my DNS parameters.
 I choose to use DoH with Cloudflare instead of the given DNS.
 Internet worked perfectly.

- On 2023-12-06 and 2023-12-07, same parameters, Internet worked perfectly on another network. - Since 2023-12-08, Internet is very slow. It need about 1.5 minute to get start.duckduckgo.com loading on any network.

 I thought it will not load at all (timeout ?).
 Others webrowsers (e.g. : Microsoft Edge) are correctly working.
 The "ping google.com" command is working normaly on windows with 2ms delay.
 The DNS on windows "Get-DnsClientServerAddress" are the normal DNS of the router.
 Even with reverting the DoH parameter to off, I do not get back my web browsing speed.

Troubleshooting :

- It's slow with "DoH and Cloudflare" activated.

 It's slow on my home network.
 It's slow on a public network.
 It's slow on another private network.
 https://www.dnsleaktest.com gives me a list of Cloudflare DNS (IPv4) near me, different from the DNS (IPv6) used by Windows 10.
 Meanwhile, Microsoft Edge, ping and wget/curl are working normally (i.e. no delay).
 Noticably, Microsfot Edge use by default according to https://www.dnsleaktest.com the same Cloudflare DNS.

- It's slow with "DoH and Cloudflare" NOT activated.

 It's slow on my home network.
 It's slow on a public network.
 It's slow on another private network.
 https://www.dnsleaktest.com gives me one DNS from my ISP (IPv4), same value as the DNS (IPv4) used by Windows 10.
 Meanwhile, Microsoft Edge, ping and wget/curl are working normally (i.e. no delay).
 Noticably, Microsfot Edge use by default according to https://www.dnsleaktest.com the Cloudflare DNS.

- In about:crashes there is not relevent crash (only old crash).

- I have not changed any about:config parameters in the 2023-12-05 to today (2023-12-12) period.

- I have run mozregression GUI with no problem.

 The program oppened succesfully start.duckduckgo.com .
 This website was choosen as it is an allowed website on every DNS.

- Firefox 120.0.1 is saying that it is up-to-date.

 And as of today, it is.

- I do have some extensions (12 activated) on my Firefox, so I try without extension.

 It worked but I do not understand why!
 * New profile. Using "firefox.exe -profile" I created another clean profile to see.
                It worked.
                According to https://www.dnsleaktest.com, my new empty profile uses both Cloudflare DNS (IPv4) and the router DNS from the ISP.
                Adding one-by-one most of extensions (6 now) to this new profile do not break yet my Firefox speed.
 * Safe Mode. Using "firefox.exe -safe-mode" I have started my corrupt profile without extension, JIT, etc...
              It worked.
              According to https://www.dnsleaktest.com, it uses only the router DNS (IPv4).

- I can send some result from about:support if needed, but it kills privacy...

Conclusion :

I do not understand why my main Firefox profile is not working correctly. I do not see strange things when troubleshooting. Nothing makes sense.

May someone help me figuring out?

Firefox has always maintained that current tabs will be restored after a reboot of the browser, and indeed that was the case for the first half-dozen years I've been a subscriber. That has not been the case for the past 4 - 6 months however. I have the correct Settings for this, so it is not on my end. Why do I always get a fresh Firefox browser whenever I update the version (which is quite regular lately . . . maybe a new version of Firefox every 3 weeks). Please help.

between this netflix error, this amazon alert, and youtube auto switching to 360p it's become increasingly difficult to access media. i've called netflix about this and they had no idea what the code was and have not gotten back to me with a resolution.

does anyone know what's causing these issues? is it just companies being hostile to firefox specifically or is something wrong?

i've cleared my cookies and cache, i've restarted several times, i've logged in and out of everything. i'm on version 120.0.1

Foxnews.com causes Firefox 102.0.1 to freeze when scrolling pages with lots of images. Closing and restarting FF does not help. The freeze reoccurs. What does help for awhile is to delete the file places.sqlite. After that FF runs for a few hours until the problem happens again. Is there a setting or other fix for this issue?

AdBlockPlus and uBlock Origin are both installed, but are disabled on www.foxnews.com.

Hello,

I just up-dated to iOS Sonoma 14.2 (I know, I should have waited a month...) and now my system menu bar disappears, whenever I'm in Firefox. It's there where it should be, all the rest of the time--every other app I've tried so far.

Some kind of new incompatibility? Anyone know how to make my system menu bar stay put? It's not the end of the world, since I can just switch apps to make it come back, but I rely on many of my menu bar icons for on-going data (e.g., the clock, timers) and I'm in Firefox a lot. So being data/status blind while using it isn't great.

Thanks!

Since approximately July 2023, Firefox gives me a beachball and pauses for about 10 seconds whenever I change between it and another app, or between one Firefox window and another. The same behavior does not occur with other browsers, likewise whether my connection is WiFi or wired.

I have No Proxy set in Network Settings. I am running a 2021 M1 Max Macbook Pro on Ventura 13.5.2.

I would appreciate any advice on how to troubleshoot and fix. Thanks.

Greetings Firefox Community

As I long time user and supporter (have donated and even got a shirt to show!) I have never had any issues with my beloved FF. If anything minor had happened, I would always find a quick fix on the community forums.

This one is an odd ball: for a while now Firefox forgets all saved passwords but only after a cold reboot (not a restart or sleep).

It's my elderly mum's laptop, which I manage for her using a remote desktop app. It's a fairly new Asus Vivobook with Win11, fully updated and free from viruses and hacks as we have installed paid versions of both Malwarebytes and HitmanPro.Alert. My Windows desktop runs exactly the same OS and those two security software, and my FF never ever forgets anything! The only difference is that her Windows and FF are set to the Italian language while mine is English.

After trying a "refresh", I exported her passwords and bookmarks and took the drastic step of completely wiping FF and even removing profiles. Reinstalled the latest x64 version and the problem is still happening.

Had a good look at both security software to ensure there was no funny setting to cause that to occur, fact is the laptop also runs Chrome and Edge with all the same saved passwords yet those two pesky browsers never forget anything!

Personally, I'd much prefer for her to continue to use FF rather than the other two, so I am shouting out for HELP, please! Hope someone has seen this and/or knows how to fix it.

Many thanks in advance and Merry Christmas to all! Cheers Paul Perth - Australia
