So my firefox recently started freezing while watching live streams on both youtube and kick. It'll freeze and buffer forever until I either refresh (kick) or hit the grey "live" button on youtube and the whole freezing thing repeats again after 2 minutes. Add-ons and internet speeds attached

Around August of last year I started getting this issue where I am unable to reach any Google related site like Youtube, Gmail and such. It drove me crazy and at some point I started using other browsers because of this issue. Sometimes my request goes through and sometimes its blocked. I have disabled my anti-virus, stopped all plugins, but all my attempts at fixing this were in vain.

When connecting to a http proxy with a username and a password it says "Proxy server refused connection"

When connect to the same http proxy and turn off its Authentication, it works.

same bug with SwitchOmega & Smart proxy

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?

I had Firefox 120.1 on a Windows 11 Pro 23H2 system and everything was fine, then today Firefox updated itself to version 122 and all my bookmarks / settings and saved passwords disappeared. When I went to the bookmark manager there were no backups to restore but when I searched the C: drive for "Bookmarks*.json*" I found dozens in the profile that Firefox is currently using (about:porfile shows my default and there is only one profile on the computer) and I copied the most recent one from a couple days ago and used the bookmark manager to restore it. However I've lost all my saved passwords and I absolutely need to get those back, how can I do that?

I love Firefox and am a committed user, but on only one of my PCs it runs so slow that I am considering switching browsers. The slowness happens most of the time, but not all of the time, except when I open more than one tab, when it is all of the time. (Neither Chrome nor Edge have any such problems.) The loading time for pages is agonizing, and I have tried the following:

• Clearing Firefox's cache (which usually fixes the problem for a day or so)
• Resetting Firefox (which usually fixes the problem for a day or two)
• Using all combinations of Performance settings (using/not using recommended settings and using/not using hardware acceleration

I am running the same Kaspersky software on this PC as the ones on which Firefox runs well, so I don't think that is the problem (although I'm not an expert tech user, I admit). I'm running an AMD Ryzen 5 2600X with 2x8 GB DDR4-3000 RAM. Please advise.

Since yesterday (12-December-2023) and continuing today (13-Dec-2023) when I attempt to use the search bar to answer a question eg "five letter words with three vowels" I receive the message 503 Service Temporarily Unavailable. I can enter Google and can then go to Google for a search.

Hello, when I open the Firefox browser from my taskbar it does not open as a full browser page as Image 3.

I have to click on the full-screen icon twice to get it open in full screen as in Image 4.

Please can you help?

Greetings, all,

I get this error messsage:

<We are unable to complete your request. Our system is currently unavailable.Please try again later.>

when i try to log on to my USAA bank accounts.

Tech support at the bank worked with me for an hour. We changed password, cleared the cache for the bank's apps, restarted Firefox, restarted the computer, all to no avail. I declined to try Google, simply because i don't trust it. Tech support person said another bank customer had had same problem and just changed browsers, which i don't want to do.

TIA for any help.

I have many webpages open in many browsers and tabs. From time to time, FF locks up, and then the PC locks up, and the only way to resolve it, is to restart (eg: reboot) the PC.

every time I check a like on tiktok a window pops up requiring to move a puzzle piece to where it fits in order for the like to register a real pain in the butt that should not be happening PS does not happen with chrome

I have no audio from Firefox browser. Every other browser and app on the PC works fine. I have tried reinstalling Firefox, and using other Audio devices (speakers, different headsets, etc)

When I restart my Windows 11 Asus ProArt PC or my browsers reopen, the positions of my tabs will shift around. Sometimes the last open tab will move into position one from wherever it was. Other times the repositionings seems random. I had an issue where I needed to reboot 3 times and in one of 4 windows a huge chunk of tabs repositioned in reverse order. I want certain tabs aligned next to others for my workflow. This doesn't happen all of the time if I have been in a window but it happens more often than not.

I have my browsers set up with Tab Session Manager to open one tab next to another. I also made a change a while ago to where if I type in a different website within a tab it will open within that tab instead of opening a new one. I only open a new tab if I want to.

I also find that despite having different sites having been opened in the same tab once I come back to a new session the previous tabs I'd opened there are gone and only the new one remains. That is less of a problem than tabs simply repositioning themselves wherever they choose. But if that is a clue to what is going on, there it is.

Firefox has crashed repeatedly when I've switched tabs to my gmail in the past ~15 minutes. It happens in "troubleshooting mode" as well. I'm running firefox on a linux computer, and my ubuntu installation and firefox are both up to date.

Here's my crash id: bp-b079d597-fb83-4a69-ab65-896370231129

The fcitx input method works everywhere on my computer except Firefox. I've added the following to my etc/environment file, which is the main suggestion I found online: GTK_IM_MODULE=fcitx QT_IM_MODULE=fcitx XMODIFIERS=@im=fcitx But it still doesn't work. My operating system is KDE neon 5.27.
