As of yesterday when I was running v119.0 I was able to screen capture streaming content from Hulu/Netflix etc, this morning after upgrading to v120.0 overnight, that capability is now lost. Video and still captures are just a black screen. Please fix!

Hello, I have been a diehard Firefox user since it was still in Beta. I have been using computers personally since 1994 and professionally since 2004, doing Windows and Linux systems administration. I can and will do whatever (within limits) you need me to do to troubleshoot and resolve this issue, which is otherwise going to cause me to abandon this otherwise excellent browser, perhaps forever. The browser.cache.disk.capacity seems to work, but browser.cache.memory.capacity does not.

Why does firefox not respect the assigned values for browser memory cache (browser.cache.memory.capacity)? Is there anything I can do to limit the memory and processor usage of Firefox and its child processes? Is extension CPU/memory usage constrained by the application values? Is there a way to determine and/or limit the resource usage of extensions?

I have included a number of screenshots documenting its behavior and generated an about:memory report during "normal use". After configuring a number of system variables, I then attempted to determine its resource usage under heavy load.

Open the browser with a couple 2, 3 tabs: ~1GB memory usage Use the browser as "normal" (dozens tabs): ~2GB memory usage Open 100+ tabs from history: The CPU and memory resource usage increases until it consumes all available system resources despite configured values. After killing and restarting the process, the tabs have invisible titles in the extension and browser, and must be closed using Ctrl+W until only a few remain after which the browser can be used normally and again consumes ~1GB.

While I understand "just don't open so many tabs", under some circumstances such as poorly written websites, bugs, etc, even single sites may attempt to claim excessive resources. I sometimes run VMs and such on this machine and in order to retain a responsive system, cannot have applications consuming all of the available resources. I have found one proposed solution that uses an external application, is this the only way?

I am open to allowing Firefox to utilize more of the SSD storage (the 1GB limit was imposed for testing) and would be fine with increased slowness due to disk cache or refetching internetworked resources. However, none of the settings I have changed or attempts I have made appear to be able to limit the memory usage in any way. Additional included screenshots are linked above instead of as attachments due to number. I can share or generate additional reports to assist in troubleshooting.

Thank you! JackD

Hello,

I have been using Firefox Mozilla for many years. This morning it opened up fine. Then this afternoon (Dec 7, 2023) it would not open for me and when I try to open a new tab it says that it crashed.

I looked and I do have Firefox as my start up browser in my settings. Thank you for any advice on getting back to my favorite browser.

Sincerely, Sandy

Hello! I need some help. Every since 4-6 months ago, Firefox has been extremely slow when I boot it up at first, with some page load times taking more than 10 minutes. Some fixes have seemed to work, but they never work permanently. From my testing, it is not the result of any extension and the issue persists in troubleshoot mode. What has not helped my testing is that, after enough restarts of Firefox, the problem goes away and web pages load quickly, so this has caused some false positives. Has anyone else had a similar problem they were able to fix? Should I try uninstalling Firefox and reinstalling it?

Firefox use a lot of CPU time ( it reaches 100% ) while watching youtube videos in 720p on Windows 10, and videos lags and stutters too much. Not using any ad blockers, non of plug-ins are on. It does work just fine on Ubuntu on the same machine Vids also were working fine on previous popular web browser known for its spyware

Using hardware acceleration is on in browser settings. Specs are: CPU: Intel(R) Core(TM) i5-3230M CPU @ 2.60GHz 4,00 GB x64 Windows 10 Home edition 22H2 GPU: NVIDIA GeForce GT 635M

Firefox version 120.0.1 (64-bit), up-to-date

I tried to pay my Wells Fargo VISA bill online as I do every month. This morning it listed all my accounts correctly on the 'Accounts' screen, but when I clicked the options to transfer money, depending on the screen I was on, it gave a message "you do not have two accounts to transfer money from and to" (not the exact wording.)

I tried to use a different path to do the same thing, and on that screen it displayed the 'FROM' accounts correctly but the "TO" account area was blank.

I had to close Firefox, load Edge, and was able to transfer the money from the checking account and pay the VISA bill.

This has never happened before and I have done this transfer and pay operation every month for years. Something has changed in the browser and needs to be fixed.

Since snap firefox keeps crashing somehow, it just hangs.. i cleared cache and all, reinstalled it, but still.. ?

They say linux is a broken system (:

when I attempt to open firefox, a window opens: xul runner error: platform version 120.0.1 is not compatible. minversion>=119.0.1 maxversion<=119.0.1 If I click the "ok" button the screen goes back to my desktop.

My online pharmacy, connected to HumanaCenterWell, no longer opens in Firefox. A message "forgerock, redirect_uri_mismatch" appears. It did work until a few months ago and it does work on Google.

Firefox (x64 en-US) is our primary browser on 2 different computers: a desktop and an HP laptop. Within days of each other, both Firefox browsers on the two computers began crashing whenever we tried to use them. There has been no error message. Nothing we have done has helped, though we have only tried to fix it on the desktop. We have uninstalled it and reinstalled it on the desktop. We have refreshed the reinstalled version. We have opened it in Troubleshoot mode and it still crashed within 15 seconds. Below are the 4 most recent crash reports from today's crashes:

Crash ID: bp-9104d928-4968-488e-ac3d-ed3000231211 Crash ID: bp-a4d3f2d0-6e18-4c22-85db-655d70231211 Crash ID: bp-dd6eafed-2fd7-4fb7-9a5b-960ac0231211 Crash ID: bp-3f979015-56d9-4a56-8f0f-d04f50231211

So I've noticed that after putting my computer to sleep, upon return Firefox will be unable to load any videos from seemingly any site. The temporary solution to this is to reset my computer as sign offs, locks or returning to sleep do not clear the issue. I've tested on different browsers/sites and can confirm that this is exclusive to firefox. I have booted firefox in troubleshoot mode, cleared my history and given the sites time to load with no luck on any of them.

Is there a solution to this?

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.

I'm a hiker and backpacker. I have recently begun using AllTrails.com to record my hikes making them easier to share with others as well as to save them for my own records. Everything works fine except uploading photos. This aspect of the app does not work at all in Firefox. It does work with MS Edge and Google neither of which I want to use.

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.

I am having issues with Firefox crashing at various times though out the day. It always starts out fine, but at some point it just stops responding and I have to close the browser and reopen it. This happens at least once a day and it does it on different units (my LG Laptop, Dell Desktops (2 different units-1 at work and 1 at home), Surface Pro 9, my Dell laptop), so I know it is not the unit, it is something in Firefox! My Dell laptop runs Windows 10, all the others run Windows 11. Please look into this and provide a patch. Thank you!

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?

Regards, eliotlencelot.
