For the last several weeks (can't give an exact date, but it's been more than just a couple weeks, less than a couple months), both my husband and I have had issues loading videos in FF. We both have the latest version of FF. I went thru "Fix common audio and video issues" and did all those things, as well as trying to load the videos in troubleshooting mode. Nothing has helped (tho now that i cleared all the cache, i'm gonna have to log back into all those websites :( ). Nothing else is problematic. Our internet connection is fine. In fact, my husband has resorted to using MS browser to watch videos--they load fine in that browser. I have no other idea what to do. Searching your database for "youtube videos load slow" only resulted in a couple hits with no resolution. Hopefully this isn't the third. thanks

Hi!

Every 10-15 days Firefox crashes on one of the machines.

The only error I have is the "No mapping between account names and security IDs was done" in the Event Viewer at the time of the crash.

Firefox and the system fully up to date. The system exhibits no other issues.

Windows 11 Pro, no domain, crashes happen on multiple accounts on that machine.

The user is not signed in at the time of the crash. They have been using the same add-ons for years, but just to rule it out, Troubleshooting mode was attempted to no avail.

AV has been completely removed temporarily to avoid any conflicts.

Everytime I load Firefox the bookmarks sidebar is not shown.

Navigating thus View => Sidebar => Bookmarks I can bring it up. It will stay visible for the whole of my browser session. However, after I've closed this session and started another. the bookmark sidebar is missing again.

How can I make the bookmarks sidr be available all the time?

FF 127.0.2 OS Windows 11 Pro v 24H2 Build(26100.994).

So my firefox crashed, I had over 50 tabs with information I want to read later when I have time, so they usually pile up. I tried to restore when I got the error when starting up firefox. It said it was successful, but there were literally no tabs available.

Is there a way to access older syncs? Since I assume my now synced state is this empty hell.

all of a sudden when I log on to hotmail dot com I get the error message too many requests when I switch browsers to edge I can log on to hotmail as normal

searched the internet but so far have not found a fix

windows 11 and firefox both up to date

Since the penultimate and now the last current update to version 127.0.2 (64Bit), the button (tile with the + sign) to add new shortcuts is no longer available. How can new shortcuts be added now?

I signed into the web browser and turned on Sync, and I did a new windows installation. When I re-downloaded firefox browser and signed in, I lost all my open tabs. Under connected services I can still see that my session from before I did the windows installation is still logged in, and I was wondering if there is any way I can retrieve my open tabs from that instance?

Thank you very much!

When trying to login to my AT&T account from fire fox the page continually refreshes and will not load. Microsoft edge will login fine. Anyone know the solution?

I need to create a pdf file to share with an agency in another country that does not have Firefox. I am unable to create a simple pdf - all of the files are automatically Firefox pdfs. All attempts to convert this file to a regular pdf have failed. Please help!

I had to do a new install of Windows 11 and logged back into Firefox and can't find my old bookmarks. I got to this point and don't know how to retrieve old bookmarks:

C:\Windows.old\Users\meljo\AppData\Roaming\Mozilla\Firefox\Profiles Please help me.

Thanks Mel

Hi,

am running firefox 127.0.1 on a windows 11 desktop. Numerous sites that use a captcha to login fail. In other words, the captcha never loads and I cannot login to those sites. Such sites include teamfaderpro, Coursera, and bandcamp. All logins fail as the captcha is required to be passed prior to logging in, but the captcha never appears and so when I try to log in, nothing happens and I cannot login.

I have tried the above same sites on the Edge browser and have no such issue, the captcha shows and I can login.

Just FYI, the agent switcher setting change recommended by others previously is not suitable. When I tried that fix I was unable to access a considerable percentage of the internet due to some cloudflare issue, so the agent switcher setting is not an option. So far, I have tried all recommended settings to fix this issue and nothing has worked.

I am surprised no one else is having this issue.

Any help is appreciated, or at least inform google/mozilla about this issue as it has been ongoing (on and off) for me for many months. And yes, this problem is persistent for me at the moment, it remains despite rebooting windows, despite clearing cookies and cache (which I have set to automatically delete when exiting firefox).

Lately YouTube playing videos have been playing super fast or skipping straight to the end. I mean, they are horribly fast.

Things to know:

• I am posting here because I can't determine whether browsers may have settings unique to them that I need to change. This also happens in Chrome, but not Edge.
• I was recently forced to upgrade to Windows 11 - I can't say this issue happened exactly at that time, but fairly recently after the upgrade. I am running Windows 11 Pro.
• This does NOT happen when playing in a private browser window, either Firefox or Chrome.
• Having the Mozilla VPN on or off has no effect.
• I am sure the playback speed is set to normal. I have tried changing the playback speed to anything but normal and then back to normal and the current video runs correctly UNTIL I play the next video.
• This does not happen with Vimeo.
• It does not happen in FF for Android.

Any questions, thoughts, or advice would be appreciated.

About once per week, I'll be using Firefox and it will stop working. I'll close it and open it again and it gives me an error message "The application "Firefox" can't be opened."

If I download Firefox and reinstall it, everything will work fine for another week and then it will do it again. I'm not doing the same thing when it breaks. It does it on both my Mac Mini (macOS 14.5) and my Mac laptop (macOS 12.7.5).

It just started happening in May on both. Nothing has changed on both that I can think of.

Hello, I use Duck Duck Go as a default search engine, with Google and others as alternatives. Since I switched my compter, Firefox resets the default engine back to ebay, which cannot be deleted in the list and also shows up in the address bar. Could you please tell me how to get rid of it? Thank you very much!
