Firefox was working well on my desktop computer until I used Avast software to "optimize the computer. Now the only software I can bring to the screen is AOL email.

Firefox is working well on my husband's laptop. So the problem has to be solely on my desktop. And is probably due to optimizing performance. I checked Avast but the Help claims no problems occur when optimizing.

Right now, I get an error of a Tab being broken.

Right now I am using Google Chrome but I would prefer to get this Firefox problem fixed.

The Firefox app I am using is the latest version, 134.0.1

'XPCOM IMPACTING MY ABILITY TO PRINT - I HAVE WORKED WITH SEVERAL SOLUTIONS NOTHING WORKS - i HAVE WINDOWS 11 MY SEARCH ENGINE IS DUCKDUCK GO WHICH I REACH THROUGH FIREFOX. WAYNE@THECRAWFORDS.COM SIGNIFICANTLY EMPLACING MY WRITING

Whenever I load Firefox, for the first minute or so, or the first X attempts at loading (any) website, I just get "Can't connect to server" errors. Eventually it does connect and then has no more issues, unless I close the browser and open a new one, then the process begins again.

New Alienware laptop with a fresh windows 11 install.

Other browsers are working fine, this is isolated to this browser, on this device only.

Things I have tried:

All the suggestions in the connectivity help section Uninstalling Firefox > Deleting my profile data from laptop > Cleaning registry > Deleting anything else that searching for "mozilla" turned up > Clean install without logging into any profile or enabling sync or importing anything (somehow still knows there was a previous install though, just doesn't import anything)

Still the same results.

I've used Firefox for probably a decade now and I am truly loathed to have to move to Chrome, but if I can't find a solution this is just untenable. Any help would be much appreciated!

Hello,

Hopefully this is something that can get answered quickly. These past few days I have not been able to use FireFox on my laptop.

It doesn't seem to be a wifi connection issue because other browsers work and other devices are connected just fine.

I also tried opening FireFox in the "troubleshoot" mode, but I am still receiving the same errors. I would appreciate any help I can get on this issue.

Below is a screenshot of the error I keep receiving.

Thanks,

This has been a problem for me for a very long time, and I'm tired of having to use chrome every time there's an update to firefox.

The issue I have is that I will get the notification saying there's an update. I click the button to update now, the browser opens the auto download page and I get a not secure connection warning. The only work around I've found is to use chrome, and sometimes I can use the "other downloads".

I'm not running a VPN, or any other networking software on my pc. This is for the full program, not the windows store app.

Sometime in the last hour or so, my Nasdaq prompts for Apple Common Stock (AAPL) and Advanced Micro Devices (AMD) failed for the reason "Problem loading page". Also this:

"An error occurred during a connection to www.nasdaq.com."

   "The page you are trying to view cannot be shown because the authenticity of the received data could not be verified."

This advice is incredibly obscure; could you translate it into some advice that I can use? Thank you,

I have a question (speculation) about having several Firefox based browsers installed on my Windows 64 PC.

I have a Windows 10, 64 Bit PC with 64 Gigs of RAM. I've always had a habit of installing several versions of Firefox based browsers - all to no avail. However, as of recent, I'm finding that my browsers begin to slow down substantially after 15 minutes or so of browsing - please read on.

Right now, I have the following 64 Bit Firefox based browsers installed on my PC - they are:

Firefox Waterfox Floorp Librewolf

I have quite a large amount of bookmarks saved, and I make sure all browsers have the same bookmarks.

I have a half dozen or so of add-ons, and have tried - from time to time - to uninstall various add-ons to see if they were the cause of the slow downs, but none of that made a difference.

For example, let's say I'm browsing for 15-30 minutes or so, and have a half dozen different tabs brought up. After awhile, things begin to slow down substantially such as delays in clicking on links and having it respond, or right clicking, etc. Browsing speeds slow down substantially also.

Here is what I then usually do:

1. Create a new tab and type in "about:memory" and click on the save memory command.

2. Go into settings and delete cache.

This normally does nothing to speed up things, and I find I have to just close out the browser, wait a few seconds, and bring it back up to things to get back to normal.

This has me speculating - "Could" it be that having a variety of Firefox based browsers with similar data conflict with each other in some strange sort of way" Or is it something else? I know that having a bunch of tabs up can deplete memory usage, but as I mentioned above, I have 64 Gigs of RAM and never had this issue before.

My SSD drive has 500 Gigs of storage, and only half is being used.

Any suggestions or recommendations would be truly appreciated.

I am receiving the words403 Forbidden when I try to connect a website that I use regularly and do not understand why this is so. Please help me to be re-connected.

If I had a clue of what you could do oter than turn time backwards, I would be happy to suggest it...how a bout tell me what I must do--other than closing the app and then opening it--??? I haven't been this pissed at a computer for DECADES!!!

Firefox (on one of my Windows computers) has begun hanging up during loading of video articles (such as news services, CNN, CBC, etc.). If I refresh page the video article will occasionally load. Often not. Have uninstalled Firefox and reinstalled. Did not help. Have another Windows laptop and there is no problem loading video content on that device. In addition occasionally Firefox will hang up just loading an assortment of websites, though this does not occur with the regularity of the non-load of individual video news articles. Thank you for any advice or suggestions.
