Firefox Support Forum

on some websites it says -1 tells Firefox to automatically determine the size of the cache based on your physical disk and setting it to 0 would effectively disable any disk cache entrys.

so are this informations true and if not, how do i still let firefox automatically determine the size of the cache based on my physical disk?

Upto Firefox v115 this website working fine. after update this website table display right side end. not in position. checked in other browser. working fine in chrome. what to do?. need solution. thank you.

I need to turn off use Firefox email mask... I can't STAND being prompted to use Firefox email mask but I can't find a way to turn off that prompt.

JUST STOP THAT! It's infuriating that you're trying to force me to use something I DO NOT WANT!

I accidentally closed both of my Firefox windows with an "x" and the rebooted my computer. After the reboot there is nothing under "History"->"Recently closed windows" and "Recently closed tabs". Is there any way to get my windows back?

Later version refuses to connect to my modem, and goes into security web mode. This modem uses HTTP/HTTPS for access, i.e., connects directly it's IP address, then the user enters a username and password. At that point, the the modem switches to HTTPS for control.

With this recent update, there is NO WAY to access the modem for any work, or upgrade the HTTPS certificate on the modem. This is a BUG.

What should happen is that if the web site will accept a HTTP connection, Firefox should NOT refuse connection or test for security issues UNTIL the user or the device switches to HTTPS.

As an aside, I've used Firefox on this Zywall modem for years until recently.

I wanted to make a lengthy post on a website today, but I accidentally hit CTRL + R twice which bypassed the "This page is asking you to confirm that you want to leave — information you’ve entered may not be saved." safety net. Is there a way to deliberately disable any and all refresh shortcuts and buttons when a safety net shows up, so my buttery fingers don't ruin my day to it's absolute maximum?

I want safety nets to be deliberately annoying.

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!

When attempting to update my Mozilla account from my Firefox settings, I was unable to add my secondary email address because of an error message stating that the secondary email account exists...

Repeating this action in case of a bug resulted in being locked out of that particular window.

I have no idea what that error message means, nor how to circumnavigate it. Please help!

Thanks, MGB

Oddball minor problem I've encountered on a recent update of Firefox, but also I switched keyboards at the same time, so I'm not sure which causing the problem. I'm on a PC, using an MSI keyboard. Ctrl and Shift keys all work, the ONLY combination that doesn't work is (left) Ctrl + (left)Shift + P. Other Ctrl + Shift key combinations work. If I hold the right Ctrl and either shift, P works fine. If I hold the right Ctrl and the right Shift, P works fine. (left) Ctrl + (left)Shift + any other key shortcut in Firefox or elsewhere works, it's ONLY the P shortcut and only in Firefox and only with the left two ctrl+shift combo that doesn't work.

Any ideas on what is causing this and how to fix it?

Hi,

Today, Firefox appeared to freeze as I was trying to sign into my Hotmail account and then crashed. Subsequent attempts to restart Firefox result in crashes. Usually immediately, sometimes after about a minute.

I have tried "refreshing" Firefox, running in troubleshooting mode, and uninstalling/reinstalling. I also performed the memory test suggested and had no errors.

There are no crash reports in the "Crash Reports" folder.

I have Windows 10 Home, Version 22H2, Build 19045.3693 (not sure if this is helpful or not)

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

Dear Colleague

this website 'https://m.nearbyme.io/search' automatically opening in a new tab. How i can stop it from automatically opening? Many other websites are also automatically opening in new tabs.

Please let me know how to stop these websites from automatically opening.

Thank you.

Since yesterday any streaming services such as Netflix or Hulu will only have green screen for the video. The sound will come through just fine and subtitles. My Wildvine is updated, I've toggled the DRM on and off several times, no changes. My browser has been checked for updates. Not sure what else to try at this point.

Whenever I open a new tab or window, I'm greeted with the Firefox home screen, which displays various shortcut tiles.

Currently, I have a shortcut for Amazon, which includes a handy blue magnifying glass symbol 🔎 indicating it's a search shortcut and not a shortcut that will take me to an URL. I'm looking to set up similar search shortcuts for YouTube and Google. I've attached an image below for reference.

If anyone is familiar with how to customize these search shortcuts in Firefox, your guidance would be greatly appreciated. Please let me know if you have any tips or steps to follow.

Release notes for Firefox v120.0 https://www.mozilla.org/en-US/firefox/120.0/releasenotes/

Among these release notes, "Firefox’s private windows and ETP-Strict privacy configuration now enhance the Canvas APIs with Fingerprinting Protection, thereby continuing to protect our users’ online privacy." How good or bad is the feature? There's the canvas blocker extension which might now be obsolete, then again without details this is impossible to anser. How exactly does the Canvas API enhance Fingerprinting Protection with this new update? The release notes don't explain that, where do i find details? Firefox should use this for all windows not only private ones.

Among the relase notes, "Firefox is rolling-out Cookie Banner Blocker by default in private windows for users in Germany during the coming weeks. Firefox will now auto-refuse cookies and dismiss annoying cookie banners for supported sites." I'm not german but would still like to use this feature as the cookie agreement popups are extremely annoying and time intensive to dismiss. Apparently in about:config "cookiebanners.service.mode" is the precise setting name. Does it have to be set to "1" to be active? This setting seemingly has the potential to replace extensions such as "Cookie AutoDelete" or uBlockOrigins Filterlists/Easylist cookie notices. Firefox should use this for all windows not only private ones.

Among the release notes: "Firefox has enabled URL Tracking Protection by default in private windows for all users in Germany. Firefox will remove non-essential URL query parameters that are often used to track users across the web." I don't get why this would only be active in private windows and germany. Firefox should use this for all windows not only private ones.

Among the release notes: "Firefox now imports TLS trust anchors (e.g., certificates) from the operating system root store. This will be enabled by default on Windows, macOS, and Android, and if needed, can be turned off in settings (Preferences → Privacy & Security → Certificates)." I've no idea what to think about this, is it a good or bad change and why? Don't try to fool me here, i want honest ansers no BS... is there potential for abuse? If Firefox uses CA's from the OS then what happens to firefox internal CA's, remain unchanged?

Among the release notes: "Firefox supports a new “Copy Link Without Site Tracking” feature in the context menu which ensures that copied links no longer contain tracking information." While this is a welcome change, i'd be much much more useful to replace “Copy Link Without Site Tracking” with “Open Link Without Site Tracking”... Otherwise there's the needless waste of time manually open a new tab and paste the link... This completely lacks any logic if you ask me, why didn't mozilla make it as i suggest above in the first place? Why the manually klick klick waste of time?

Lastly a question unrelated to this update, when RFP is enabled and the browser-screen-size is spoofed, if i go into fullscreenmode by accident, will this expose my true resolution or not?

I was working in Firefox, everything was working fine and all of a sudden, by tabs began to crash. I only had 2 tabs open. I opened Firefox in Troubleshoot Mode and still, the tabs crashed. I opened More Troubleshooting Information and tried to Refresh Firefox, but it appeared nothing happened.

I do not want to lose the Bookmarks I have saved!!
