Firefox Support Forum

I've been having an issue for a while now where the cloudflare challenges that ask you to click the check mark to "verify your connection is secure" would just endlessly ask me to click the button and never continue. Sometimes it would say to unblock access to challenges.cloudflare.com.

But if I a launch an incognito window I can visit website with the challenge and it won't even ask! I've added all my extensions to run in incognito mode and everything still works, I can visit the websites in incognito just fine. So the one changing variable is incognito vs non-incognito.

I can have two windows open, one incognito and one not, and browse to the same website and the non-incog window will fail but the incog will just go to the site.

I thought incognito was supposed to only affect the session storage? Does it silently change other things to the running environment of the browser (about:config options, slightly different extension configs)?

Anyone know why this small change would suddenly allow cloudflare challenges to work?

Hello,

I need help i'm using polish language always on many websites.

When i typing letter "ó" which using key combination Right ALT+O always my brower opening "Open file" dialog window. this is annoying always.

Many sites write that it can not be changed?

Why does the browser open this dialog with this shortcut when there is another shortcut for it? Ctrl+O. Why two another shortcut doing te same job?

I stream video and after 10 minutes, graying out of screen or simply the steaming stopped. Repeatedly same problems. Problem for same streaming not seen using chrome.

I do online payment and screen locks up. I refreshed... no change. I paid in chrome... no issues Now notified that I may have paid twice. WTF?

Why suddenly problems with firefox.

Running Linux mint

Firefox seems to crash repeatedly and generates no crash reports, just freezes up my pc. It works in troubleshooting mode but even after refreshing, the problem persists. Surprisingly, it will consistently crash if I go to `about:support` (except in troubleshooting mode). Any help would be appreciated!

I'm the tech director (tech janitor) for a public school that is using Securly.com for their Internet filter. Securly requires installing their own certificate so they can be a man-in-the-middle. I've installed that cert into Firefox and that works fine. However, even with that cert installed, Sync doesn't work when I'm behind that filter. As soon as I take one of my computers off the school network, everything will sync up. I don't get any errors that sync is failing, it's just not working. Any ideas on how I can fix that issue?

Thanks!

HTTP/3 doesn't work regardless of my config:

network.http.http3.enable = true network.dns.httpssvc.http3_fast_fallback_timeout = 0 network.http.http3.priority = true

and https://cloudflare-quic.com/ and console still show I'm using HTTP/2. Tried on Firefox nightly and chromium (chromium works fine but firefox doesn't.)

Your Firefox profile cannot be loaded. It may be missing or inaccessible

on debian 12 linux

I tried `firefox` `firefox-esr` `thunderbird``firefox -P`. I also deleted `~/.mozilla`, `firefox -p presaved-profile-dir` stay the same.

the `firefox binary` and the `profile dir` are all useful because I saved them to zip file and use them every day. So is there any other dir besides the 2 dir which fails the startup? even thunderbird fail with the same reason.

Help please, thanks!

When you open a link from the sidebar while holding ctrl, firefox opens it in a new tab and switches to it immediately; whereas when you click a link from a webpage with ctrl, it does not switch to the new tab (unless you hold shift as well, or check "When you open a link, image or media in a new tab, switch to it immediately" in settings > general > tabs). I would like if firefox does not automatically switch to opened links from the sidebar (history, bookmark, etc.), when I open them with ctrl? (I know I can hold shift to do that, but I was wondering if there might be a preference in about:config to change the reverse this behaviour for sidebars)

Thanks, Ibr.

Hello everyones,

My firefox on my ubuntu give me to "bug" :

first "The bookmarks and history system will not be functionnal..." second, when i try to sync sign up : "error 500"

What i have try, "rm -rf .mozilla .cache/mozilla" i have download latest version and execute "firefox-bin" i have try to chmod 777 all this folders and under folders...

i'm working on it from three hours and have read many solution on firefox support or others website, no one works...

So can you help me ?

I'm trying to use Microsoft Teams in Firefox because the native app for Linux is abandoned and crashes, and at first sight the app is blocking Firefox on purpose. Buttons to make calls are disabled, stating that audio and video are not supported in my browser, but everything works normally if join to existing calls using e.g. links.

Is it possible to trick Teams to think I'm using Chrome? I found the "User-Agent Switcher and Manager" add-on, but I can't figure out how to possibly use it.

117.0.1 Mozilla Firefox Snap for Ubuntu installed Total Adblock installed Enter URL "my.yahoo.com", the "My Portfolio" page comes up, the portfolio box presents a message: "Oops, something went wrong. Please try again." I went to Settings, Manage Exceptions, entered "https://my.yahoo.com" and clicked Add Exception. "https://my.yahoo.com" it appeared in the Website listing below. I clicked Save Changes. I retried the My.Yahoo tab again and the same error resulted. Where do I need to change what preferences, Yahoo or Total Adblock?

I was having trouble switching and logging out of Twitter so I thought I could just clear site cookies to make it work, but I weirdly discovered "about:preferences -> Manage Data -> Remove Selected / Remove All Shown" has no effect. i.e. after clearing, when I open up manage data again, they are still there. I did not try "Clear Data" above it because I was afraid of clearing out all my logins.

I reinstalled my computer several weeks ago and current profile was directly copied from my last machine, so this might be a possible cause? Could someone be so kind to help me get remove cookies and hopefully twitter back to work? Thank you in advance.

Today when I closed Firefox and reopened it the option to restore previous session was not shown, as a result I have lost half my pinned tabs (I managed to redo the rest from bookmarks) which were vital. I tried going into history but the option was greyed out.

This happened yesterday too but after redoing half my tabs I went to open gmail and it restored all my tabs, I tried the sane today but it failed so am stuck with half my tabs.

Please do not suggest I use synch as I only use one device.

Same as the question.

The display shows some icons on the last tabs I opened but it seems only some basic website layout is loaded but all the details are gone. Like text, button borders, even the exit, fullscreen and minimize buttons. I have seen that this has been an issue for quite some time before so I am looking if there is a fix or a workaround. I have and Nvidia graphics card and drivers if that means anything. And my swap file is 20 GB and my RAM is 16 so the space shouldn't be a problem. It gets fixed when I turn off Firefox but not when I refresh tabs.

The crazy thing is that when I take a screenshot inside firefox (with firefox integrated screenshot option, like when I press right click and then take screenshot. I can see the text so it seems like it is a display problem but this only happens with firefox and not other apps.

Appreciate all the help. I will ask of ubuntu formums next if I don't find a solution here.

Thank you all for reading and answering!

I ran a loghttps://pastebin.com/jydVHHs0 of playing a youtube video mediaencoder? not sure if encoding issue or something else

The videos take a long time to play. I upgraded my system recently and was removing and reinstalling audio-related utilities with DNF.

Hello. I recently moved from windows to Linux Mint, and noticed the behavior of the Picture in Picture window is different when resizing. On windows, the aspect ratio is kept. while on Linux, it is free form, making these black bars around the video, so I have to resize it very carefully to not show any black bars.

How can I make the PiP on Linux behave like on Windows? That means resizing keeping the aspect ratio.

Attached are the comparisons between Windows and Linux Mint.

Thank you very much!

The problem is that even after I've tinkered with the about:config settings to prevent Firefox from restoring my previous session after a crash, it just won't listen! The changes I make in about:config don't seem to save, and every time Firefox crashes, it happily reloads my old tabs and windows.

Your assistance would be greatly appreciated!

Fix the confirmation email process so it works. Tell me how Firefox lost my signed in status. Tell me why there is an added 1 after my user name of bth73. Drug test your employees for meth usage.
