Firefox Support Forum

I sometimes have a problem connecting to a URL. It does not make any difference which URL. Microsoft Edge has the same problem when this occurs.

I have two network connections. One is via Ethernet and one via WiFi. I generally don't connect the WiFi since I am sitting next to my router. Yesterday, when this occurred, I connected the WiFi and everything worked. I thought it had something to do with my WiFi, but today when it failed I tried the same thing and the problem continued.

I ran the Microsoft troubleshooter and it displayed that I was connected to the Internet.

When this occurs I can ping my router successfully, but I cannot connect to my router via Firefox or Microsoft Edge.

Today I rebooted my router, even though other devices do not have a problem connecting to the Internet, and when the boot was completed everything worked. When I rebooted the router my PC indicated that it did not have a connection and when it was able to access the router initially it indicated that I did not have a connection to the Internet. When my PC indicated it had an Internet connection Firefox functioned correctly.

I have a UPS which has my router, modem, and desktop PC connected. We have had power failures and either my PC is turned off or I turn it off. My router and modem continue to function and we can access the internet via tablets or cell phones. I was wondering if the power failure somehow could have affected my network provider and I needed to reset my router so that it could establish a new connection to the modem. Don't know if this makes any sense or not.

I have Microsoft Office 2021 which is Microsoft's perpetual license version of Office 365. I use Outlook in Microsoft Office 2021. What surprised me is that when this is going on Outlook will function correctly.

Is there anything I can access in Firefox that can help me determine what is going on, or do you have any suggestions?

For a while now, several bank credit card sites are not working correctly when I use my Firefox browser. It did in the past and I didn't have any problems but lately I'm having these problems happening on sites I've used for years. If I use another browser it will work with no problem. In fact after talking with some of the support people at some of the sites that won't work, the suggest trying another browser which works fine. I'm talking like American Express' website which I use a lot. There are other sites other than credit cards that are not working correctly and again, their support agent will tell me to use another browser. I have tried different remedies like clearing cache, history, etc. I only use few addons like AdBlock which helps to cut down on trackers and information gathers. I have set my preferences to clear out my history and cookies. I have used Firefox for so many years without problems and with the same addons without any problems. So what is causing this to happen? I do enjoy using Firefox but if I have to keep changing over to another browser so sites will work, then maybe it's time for me to stop using Firefox.

Hello Before I reset my PC some months ago, I almost never had to Login to sites, as the kept me logged in. This no longer happens, and now I frequently have to Login to eg. my Google account which needs third party autho and all sorts. It is rather annoying having to Login to Google every time I close the Window.

I do not have this setting on: "delete cookies and site data when Firefox is closed" I do have this setting on: "Ask to save logins and passwords for web sites"

It does save my Password and autofill, which makes it easier. But it is still annoying, that I have to login to everything every time.

I have tried reinstalling Firefox, to no avail.

Please Help

why doesn't my theme stay engaged?I have 4 computers and I am constantly having to engage my fav theme on them all all the time.

Theme: Animated Dark fox theme with spinning globe and glow effect.

I imported my bookmarks, but they're not displaying in the bookmarks toolbar. I've tried hiding it and unhiding and restarting the program/my computer. The imported bookmarks can be seen when I go to "recent bookmarks" in the manage your bookmarks section. It also says that they're listed in the bookmarks menu, but they're not visible outside of the manage bookmarks settings window.

Firefox (a new up-to-date install) has been very crashy on my new computer -- PC running Windows 11.

I ran troubleshooting mode and it shows 0 crash reports.

On my old computer, I had 4 Firefox windows open, a half dozen extensions, ~200 tabs and it was quite stable. This brand new install is running one window, 3 extensions, a dozen tabs open, and freezes and crashes pretty much every time I try to read my email (or do anything else that involves clicking).

How do get a stable Firefox?

I reset my windows 10 installation thinking that it would be similar to a "backup and restore", but it wasnt. I wiped out nearly everything I had installed.

I hope that can learn how to load bookmarks from saved favorites folder.

Any help?

I am an experienced Firefox Add-On user.

I have installed Firefox on a new build Windows (10) computer. Only 4 of my 8 installed Add-Ons will show on the Task Bar

This is not a problem on my two other Windows machines that share the same Mozilla account for Bookmarks & Passwords. (Other machines are also 4K displays).

I have uninstalled then reinstalled Firefox several times on the new machine, nothing seems to work.

I suspect there is a simple fix, but it eludes me.

Suggestions?

Hi, I read through another thread where someone was having this same issue and there was no resolve because no one seemed to understand the issue. My issue is that I can't clear the "Save Files to" setting under "Files and Applications\Downloads" and leave it at "Always Ask". What I wind up with is a lot of clutter in my Downloads folder. So my question is, How do I correct this setting so FireFox stops saving files in places that I don't want them saved?

Hello Mozilla Support,

Since 2 upgrades ago, anytime I try to watch a livestream, my browser slows right down and then crashes.

I don't care why its happening, I just want a definitive fix for the issue.

I'm so aggrieved at this happening constantly, if you cannot provide a firm resolution to this issue, i will simply move to another browser.

I've tried your about:config setting restart to false and other fixes but still keeps happening.

I await your reply.

With Regards,

Mark

This happens now a lot, sometimes I can uninstall Firefox reinstall and it works. That worked this time but only for a few days. I am back once again to where I get this error on every place I visit. I have cleared my cache etc.. uninstalled reinstalled did a restore. It is only Firefox all other browsers work fine. No idea what to do anymore and am sad because I prefer Firefox. I only have standard windows 11 home security stuff installed so nothing special or fancy firewalls. Tried turning on default fire wall. Tried all the instructions on the more info page the error screen leads to.

This error occurs on most all websites or places I need to log into

Secure Connection Failed

An error occurred during a connection to mail.google.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

Anyone know why this is happening and a solution?

I make frequent use of the Windows system-level keyboard shortcut Windows Logo button + M to go directly to the Windows desktop. Firefox does not respond to this keyboard shortcut by minimizing. How can I fix this? I already tried refreshing Firefox. This is a big enough issue to get me to abandon the browser, since I depend on keyboard shortcuts.

I am running Firefox 121.0.1, which is currently up to date, on a slightly older MacBook, which has the latest MacOS it can get: macOS 11.6.8. As the title states, YouTube is almost unwatchable on my machine. The video will pause frequently while audio continues, motion is not very smooth, which is especially noticeable watching sports, etc. I cleared cookies and cache, I have run in Troubleshoot mode as well as tried flipping some switches in about:config that I've seen in YouTube videos and forum posts about similar issues, but nothing has solved this issue.

YouTube in Google Chrome works fine, and I've been watching HD YouTube on this laptop with it for years without any issues, so I doubt it has anything to do with machine specs like RAM, CPU, etc.

I was hoping to make Firefox my new browser and start supporting browsers that aren't chromium based since Google Chrome is going too far with respect to privacy and the freedom to use the add-ons I like (e.g. adblockers like ublock origin), but so far I have not been enjoying Firefox for YouTube. Any help would be greatly appreciated.

Hello, My Antivirus sofware (GData Internet security) showed the attached message (in German) two times today. It says in English something like:

It was tried to access an infected archive

Virus: Trojan.GenericKD.71195125 (Engine A) File: 0B3C6E11DBBC160A3AAFC100C8BAB878F5EE0C Directory: C:\Users\re-ge\AppData\Local\Mozilla Firef Process: firefox.exe

The line ending with "Firef" may indicate that lines are truncated.

Any suggestion what to do ? Reinhard

I am having a problem with my Firefox homepage. There are several things going on like the red, yellow and green dots on the left side of the menu change to light dark. Some of My Bookmarks appears twice and one was added. I did a Refresh and troubleshooting but to see if my home page would go back to normal but it did not. I think I have a bug that is causing these changes on my Mozilla Browser. I need to get the browser back to normal.

Is there a way for me to retrieve my bookmarks? They have followed me through several macbooks, and reinstallations and this is the first time they've gone missing.

When I open Firefox on my new computer all the bookmarks are showing at the top. I only want my default bookmark toolbar to show. The only solution I could find was to drag it into the toolbar area.
