Firefox Support Forum

I am using https://infiniteajaxscroll.com on my website https://madway.net . When I scroll down and new set of topics loads, if it contains html5 video it will not load, stay loading. Works fine on Edge browser and Android browser.

Using latest Firefox.

Having used Thunderbird for some time, I installed it on a new PC, and found that virtually all my emails on a particular account seem to have been deleted, despite the app being set up to retain them. I checked on the webmail (BT) and they have gone. The account is set up as IMAP - as is another account on the same server, which seems OK. BT won't engage with me on this as they "don't support third party apps" I assume that 3 years worth of important client history is gone for ever? Can anyone suggest what I did wrong, or is this a software failure?

hello. I have a reproducable issue with Firefox. If I use the touch keyboard on Firefox and then exit Firefox without without closing the touch keyboard, when I next start Firefox it only opens with a half view. if I close the touch keyboard first and then exit Firefox it opens as normal in a full screen view. it has nothing to do with either an extension or a theme. is there any way of ensuring that FF opens in full screen view if I forget to close the touch keyboard before exiting the browser? thanks in advance. PS: device is a Surface Pro 7 running Windows 11.

When Firefox is in fullscreen mode and Windows taskbar is set to autohide the taskbar cannot be accessed unless I press the windows key to bring up the entire start menu. Once the start menu has been accessed and the same window is in focus, it works as intended by moving the mouse to the bottom of the screen. Switching windows breaks the function again.

For Windows version 10.0.19045 Build 19045 If using Firefox Version 113.0.1 (64-bit) in Windows 10 and in the following state:

 Firefox is open and window is maximized.
 Firefox Full Screen is toggled OFF.
 Windows taskbar setting "Automatically hide the taskbar in desktop mode" is toggled ON.

Then the Windows taskbar will not display when the cursor is place at the bottom of the monitor screen. If the Windows taskbar setting "Automatically hide the taskbar in desktop mode" is toggled OFF. Then the Windows taskbar will also not display. Changing the ON/OFF state of any other Windows taskbar display setting in any combination does not fix the failure.

When Firefox is launched to maximized, the Windows Taskbar does not display when the Taskbar is set to Hide. Firefox takes over the entire screen. When I use two monitors and Firefox is on the second monitor it the toolbar is visible.

How can I stop this from occurring?

At some point, I've noticed that certain behaviours expected to occur when pressing the Escape key no longer did. Those behaviours mainly involved triggering some Javascript, including functionality in keyboard-related extensions, such as Tridactyl. Browser-level functionality on the other hand, such as pressing Shift-Escape to open `about:processes`, or pressing Escape to close Search Suggestions when the URL input bar, continue to work as before.

Upon investigation, I found it is specifically the javascript Keydown event that isn't being registered, while the subsequent Keyup event still is. I used https://w3c.github.io/uievents/tools/key-event-viewer.html to test this.

I also found that starting Firefox in Troubleshoot Mode (Safe mode) doesn't resolve the issue. On the other hand, creating a new profile does.

I've looked at the modified settings in `about:config`; there's a lot, but nothing stands out as being related to keyboard input or javascript.

Can someone please help me find what is causing this?

Please HELP -- I can no longer use Thunderbird or Firefox to access my emails at the University of Vermon (UVM). For over about 2 months after the Univ. of Vermont went to a new email system, I can no longer use Thunderbird or Firefox to get my emails. I get an error message when I enter my NetID and password at

https://adfs.uvm.edu/adfs/ls/        or   https://webauth.uvm.edu/webauth/login?RT=ZQy0vGaH7hXE%20BIXYqeBrf8AW817EA2ZEgHD5NywxXEKicTPOPs4jvfqMM1T9WiTY2sJpxG3mUbgwZ%20oW%20wliuVFGhQ9vFzD12bdJTM4FXUcyuQi%2Fo6%2F7zhAZ2ez%20uYFe0ds5tUDcQVhf%20jzr0i1MSDJlBZ%2Fqp6YXfHB3zHgNlGsV3eb0QbClx9lt6AtFahFGLLykYMswanRENJNTkXaRe%2FHypzNXIcppX22Ota7hGSkkVx7g2ChYFxgPaK2W1xDgpAMNS8O1F6HfjOao96aRrWOo4Ltqb0jfSHYpYRjantewrxjZUHG9yiLS1yI6C3YR06tb84wb6%2Fs4lUrDAJadCfJz3GJP8qkOJyrSmjI0%20%20WMo8U;ST=ZQyp228WbdkSw1QKFNvUgJvqzpLVg0x5cQFiBGwk3jd9QLdWxEo7Wg90eK09yvoz1npFIMkViO0k3J3d8%20prFPvXmkpA99rhjvwO9qDqHU8ZvduICJM8IjgoqGCTfAUUjg3k280qveVCzlkbyJtJ4rga3RFnod9IrEbgHy2dgeBcXuop;test_cookie=1

Hi! I have two Firefox accounts, one for work and one for personal use. I often have them running on the same computer at once (this does cause them to crash occasionally, but not often enough to be a problem). However, today I tried to log into a website where I regularly do freelance work and received this error code: "Error code: SSL_ERROR_PROTOCOL_VERSION_ALERT"

I would assume something was wrong with the website itself, however when I went to that same site on my other account, it loaded just fine. I've restarted my computer, restarted firefox, deleted cookies and caches and browser history, but still get the same message on my work account. Any idea how to fix this?

Thanks!

I am trying to access a site for a public utility in Israel, with the country-level domain .il. Firefox continually reports this as '403 forbidden'. I've cleared the cache, which did not solve the problem, but am reluctant to take other measures since I don't know their side effects.

Is this an anti-Israel setting created within Firefox as part of a BDS campaign? Or has the system been hacked by BDS supporters or similar.

EDIT: I've solved it by installing Kaspersky's extension. I have been troubled by an issue that every time I perform a search on some websites, the page will first freeze for ~10s, during which I can't click on anything on the page. However firefox itself is not totally freezed, like I can switch tabs without any issues, but if I click on the icons of extensions (such as my adblocker) it won't give me any response. After the freeze the page started to load normally. I have tried disabling all extensions, reinstalling firefox, updating to beta, and disabling security.tls.enable_0rtt_data, but none of these works. Other browsers on my device work normally, including Edge and Chrome. Websites that freeze during a search: Google, Bing, Musescore, Duckduckgo Websites that DO NOT freeze during a search: Github, Youtube, Twitter I have encountered this issue both on 117.0.1 and 118.0.

Basically as the title says. The only sites this is an exception for is youtube as well as big streaming services but on youtube the video seems like it takes longer to buffer and has a lot more pauses.

I am on Version 117.0.1 which was installed on September 12th for me. I did not notice any issues prior.

I am on a macbook air which is updated to latest software.

I have tried the following:

Running it in troubleshoot mode. It did not fix the issue.

Turning on/off autoplay. It didn't work.

Clearing cookies/cache. Nothing.

Started firefox without a theme. Didn't do anything.

I unchecked "Use hardware acceleration when available." which did nothing.

Sites I have tried watching videos on include:

reddit

pornhub/other porn sites (for testing purposes...)

instagram

Vimeo

Recently, about one out of four webpages that I try to visit seem to fail to load on FireFox. This is FF for Windows, and is the most updated version. This issue even occurred just now when typing in MOZILLA.COM. Everytime one of these pages fails I attempt it with Chrome or Brave, and it works just fine. It does not matter whether they're ventured to through Google links or other links, or whether I type the address in manually. It only happens sometimes, as other times the same page loads just fine.

I was asked to close Firefox to download a new version. After that I can't get Firefox to open at all. Every time I try I get a window stating that it can't open and ask me to report to you. Best regards Gunnar Herrlin

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!

Youtube and Twitch both have a delayed response to un-muting. After turning on the audio, it takes about 4-5 seconds to hear any audio. Youtube has long load delays each time rewinding or pausing. I tried on chrome and I didn't get these issues. I also already cleared cache and history.

I have been running into an issue any time that I try to open Firefox, I recive a pop up stating "Your Firefox profile cannot be loaded. It may be missing or inaccessible."

I have tried all of the suggestions noted within the Mozilla support and documentation.

I am running Windows 11 and was using my machine normally. I cleared the cache within Firefox under the settings and was able to use the browser for 20 more minutes without any issue. I tried to open a second Firefox window and received the Profile Missing error. From here I closed out instance of Firefox which I had open and tried to open up Firefox again. I was greeted with the same "Profile Missing" error.

When I navigate to the location of the Firefox profile (%APPDATA%\Mozilla\Firefox\Profiles\) there exists a profiles.ini file along with a "Profiles" folder.

I have tried deleting the profiles.ini file, as the Mozilla documentation says that doing so will cause Firefox to generate a new profile, however after doing so I continue to receive the "Profile Missing" error.

I am unable to access the Profile Manager within Firefox to make changes to a profile or create a new one as stated within the Mozilla documentation, due to the application being blocked by the "Profile Missing" error causing the browser not to open.

Hello,

After Windows11 last udates, audio disabled in only the Firfox browser (such as when using Youtube and all other audio included sites) while audio working properly in Microsoft internet browser and in rest of my PC apps, I tried many ways including update firefoxB , tweaking windows11 but all with no result.

Thank you

Firefox opens blank tabs when following link on existing logged in websites, for example Screwfix. Worked previously, suddenly stopped yesterday. Refreshed Firefox, no change. Re-installed Firefox, no change. Site works fine in Chrome and Edge, so not site error, internet error, PC error, or network error. Please help? Thanks, Mark
