Firefox Support Forum

I have Firefox Version 94.0.2 (64 Bit) running on Windows 11. First, I noticed Firefox was running very slow. It loads up slow and webpages are loading super slow. I downloaded other Browsers and they are working just fine so this tells me there is an issue with Firefox. After a while, Firefox would randomly crash for no apparent reason, while loading a new webpage or installing an Extension. I have sent Feedback for every crash. I have closed all of the Tabs I can that I am not using on Firefox, cleared the Cache, Cookies & History, Restarted Firefox & my PC and everything I can think of. Now, I just started getting an Error Message at the top of Firefox that says this: Firefox is running out of disk space. Website contents may not display properly & it includes a link to read on how to optimize disk usage. I followed the Instructions in that Article and it did not help. I am at wits end. I am ready to Uninstall and Reinstall Firefox and see if that fixes the issue but I hate to lose all of my Extensions and ETC. Can someone please help me with this? Is there anything else I can do to speed Firefox up, stop the crashes and get rid of that error message?

Hi all,

Since I switched to Win 10 Firefox constantly crash on my computer.

• Tried fresh install no change
• Tried repair no change
• Switched off extension and then on (one by one) no change
• Deleted cache - History - etc .. :( it worked for only a few days since I did a full scan with Microsoft Defender.
• Since this last crash (as I could not launch Firefox anymore I used shift + click on Mozilla shortcut)I decided to switch off the graphic card acceleration and all the other option in this menu and it seems to help

Could you tell me how to send you the crash report ( I do have 8-10 of them already sent to Mozilla)

I had a problem a while ago with crashing, which i was able to get fixed thanks to this but now i have a new problem. It seems that firefox is having memory problems of some kind, for example, i can't even get stream raiders to load.

As of today, I'm no longer able to log in to the accuweather website. They tell me: "A new version of Mozilla (Firefox) was released on Tuesday, Jan 11th, and Professional/Premium subscription users are receiving a FAILED LOGIN error when logging in. Until Mozilla resolves the issue with their new version that prevents a successful login, you will need to use a different browser. We apologize for any inconvenience this may cause. If you have any questions regarding the Firefox upgrade, please contact Mozilla Support." Can you resolve this new issue? Thank you. Wendy Tobler

Firefox 99.0

I guess it's a problem with the latest update because it didn't happen to me before. Gmail keeps showing me this message: "Gmail is having authentication problems. Some features may not be operational. Please try logging in to troubleshoot the problem." I have relogin, deleted the cookies and site data but I still get that message. I have tried starting the browser from "about:support" in troubleshooting mode but the error still appears. This does not happen in other browsers.

I have been trying to get on the Malwarebytes website, but I keep getting;

Your connection is not secure

The owner of links.malwarebytes.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

links.malwarebytes.com uses an invalid security certificate. The certificate is only valid for the following names: *.fortinet.com, fortinet.com Error code: SSL_ERROR_BAD_CERT_DOMAIN

This happens with all of my web browsers. Is it safe to allow Fortinet ?

Whenever Firefox tries to sync, which is naturally happening on startup, it crashes with no error messages. I ran Firefox in safe mode by entering the command firefox -safe-mode and the same thing as before happened, but before it crashed, Firefox wrote Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Segmentation fault in the console, and then exited to the command prompt. Help!?

I note that there are 399 posts referring to this problem. The problem has existed on my PC for about 4-5 months.. DELL support has checked my computer, we have cleared cache and browser and tweaked other controls but nothing helps. I have no problem using Google Chrome. If so may people are having the same problem surely Firefox should be making an effort to fix the bug??!! Just drafted a reply to you from Firefox site but as frequently happens message appeared -

 Something about oops and an error message. When it occurs drafts do not save and messages do not transmit.

Sorry the screen print will not copy across.

I use Firefox as my main browser and it is inconvenient to have to swap between Firefox and Chrome

Can Firefox please fix this problem?

thank you mlmg

In trying to reach at least one Web site (maybe more), https://jabberwocking.com/, I get an error page, Error 523: Origin is unreachable. It also has some tech stuff I don't understand. What can I do?

A couple users at our site intermittently receive a SSL_ERROR_BAD_MAC_ALERT error when navigating to Google in Firefox. This happens in Version 99.0.1 (64-bit) on Windows 10 computers. When the issue occurs, users can navigate to other websites without issues. Navigating to Google in a different browser works no problem. Restarting the browser will resolve the issue. Clearing cookies and site data has no effect. Users can also refresh the page after some time and the issue will go away.

Any idea as to why this is happening?

Every time I need to upload something to a website, when I click "browse" to browse my computer for the file, the window to browse my computer never pops up. I don't know why it randomly stopped working.

You actually have an egregious error in your install procedure/program. 1) you fail to tell folks/warn them close down i) FF when installing the update and/or ii) save and delete all open sites in the FF being upgraded. 2) there is a failure to TELL us reboot FF after the install.

Doing research and writing all day long as I do, I actually hold a number of reference sites open in FF as I work.

My friend who happens to understand all this computer stuff tells me that the open sites on my FF is what impeded the successful install . . . .

The other grumble I have with you-all is that it has taken me too much time to try and find a way to respond to you with the information needed to solve this problem for the FF community . . . .

I am a paying/donator to FF . . . and I must tell you I am beyond disappointed by all this dropped ball on sensible communications practice!
