Forum d’assistance Firefox

Since the update to version 125 Firefox on Windows 11 (all updates installed), when I open a new tab and start typing to the address bar WHILE the VPN to the office is active, Firefox locks up and can not be used anymore.

In taskmanager, there is no spike in memory or cpu usage visible. All I can do at this point is to kill Firefox via taskmanager.

I can enter anything in the address bar of an already open tab with an other website open, I can open new tab from the bookmarks, but I can not open a new tab and start typing in the address bar while the VPN is active.

Once I disable the VPN to the office, everything goes back to normal.

I never had this issue on a previous version of Firefox.

Any ideas whats causing this?

I have two end users that are having a different issues but they are of similar nature. First user can not upload anything to Microsoft Share point. She gets a message that says she does not have proper permissions to upload. She does not have the same issue on Chrome or Edge. The second user is trying to download and or save a file from a couple of different websites but regardless on where she tries to save it on her computer it says she does not have proper permissions to save to "x" file location. She also does not have this issue when she is on Chrome or Edge.

For both users I have tried clearing cache and cookies, Rebooting their computers, uninstalling and reinstalling Firefox, deleting registry keys/user data from the computer itself. I have had no luck with resolving this issue and I can not find anything online that remotely resembles this issue.

Thank you and please advise

After the latest update to 125.0.2 (64-bit) the browser works fine for a few minutes and then pages won't load. It starts working again after a restart [ for a few minutes]. I have cleared the cache & data. Chrome works ok.

Hello everyone,

since my last update (125.0.2 (64-bit)), an additional website always opens when I open a website in Firefox. This is called "Page load error" in the tab; the content of the page is as follows:

Error: Connection failed

An error occurred while connecting to 0.0.0.1.

   The website may be temporarily unavailable, please try again later.
   If you are also unable to access another website, please check the network/Internet connection.
   If your computer or network is protected by a firewall or proxy, please make sure that Firefox is allowed to access the Internet.

How can I prevent this additional page from opening?

Thank you in advance for your help!

After Firefox updates itself, the restarted browser session is unresponsive to mouse clicks - can't follow links, can't respond to UI dialog boxes, the browser is unusable for practical purposes. It's fixed after another manual restart. This unfortunately breaks all the streamlining Firefox has done to restore the session after an update, because none of that stuff works the same after a manual quit and restart. This is happening on MacOS, and it happens across multiple computers.

I'm running Firefox 102.4.0 ESR (32 bit) on a Win-7 (32 bit) PC.

It works fine. I visit a LOT of websites, it works fine.

Until just now. I'm trying to bring up namecheap.com (a domain registrar) and I'm getting this message:

Secure Connection Failed An error occurred during a connection to www.namecheap.com. security library failure. Error code: SEC_ERROR_LIBRARY_FAILURE

I'm not given any option to alter any FF settings or to otherwise create an exception to "trust" this site to be able to access it.

I've read where changing security.pki.crlite_mode (currently 3) to something else (like 0) and I've tried that, and unless I have to close and restart FF for that to take effect (which I have not done) then that setting doesn't fix the issue.

What exactly is going on here? Why is only THAT SITE giving me problems?

This is a problem I've had for a while and thought it would be eventually fixed, but no luck so far.

TL;DR - Almost every time I add or remove monitors my Firefox hangs.

More context: I use a PC laptop and constantly switch from using just the laptop screen to using just a set of two monitors, with the laptop closed. What I do is, I lock my machine, with Firefox open on the laptop screen, connect the monitors, close the laptop lid, and unlock the machine. That causes Firefox to hang and I'm forced to kill it and open it back again. It usually reopens all tabs without a problem but the issue is pretty annoying.

My current version is 125.0.2 and I'm sure the problem dates from several versions

Out of nowhere, my cursor speed in Firefox has slowed to a truly unusable crawl. I refreshed a page and it was suddenly inching along at worse than a snail's pace. I'm using a USB trackball mouse. This is only affecting Firefox; no other applications have this issue. Using Windows 10.

Here's what I've tried so far:

• Restart Firefox
• Started Firefox in Safe Mode
• Restart computer
• Create a new profile in Firefox
• Check my mouse's firmware
• Try a different mouse

There was another question about this years ago, but the accepted answer about accidentally enabling a Windows accessibility feature doesn't say which feature it is or how to disable it (if that's indeed the case). The link also seems to redirect to a generic accessibility page.

Greetings everyone,

I've had this problem for a while and I don't know what to do.

I had a problem where Firefox kept crashing before it had finished loading up all of my former tabs and windows and so I was given the option of opening Firefox in "Safe mode" which I did, but now Firefox only starts in "Safe mode"...

I'm running the most up to date version of Firefox.

Thank you for any help!

When I run firefox on WSL2, buttons dont work on any pop up windows. Foe example when installing a firefox extention - it will download and pop up a small window at the top right to add the extentionto firefox. The buttons dont work. Another example is when opening up the firefox menu bar (hamburger bar) - it will pup up a small window to allow to open up settings, go to add ons, open bookmarks or history. The buttons dont work. Last example is the pop up window for this Ash your question page for firefox support - When clicking "Which topic best described your question - it will pop up a small window to select what type of question Im gonna ask. The buttons dont work.

I dont know how to fix this. I restarted, deleted my firefox profile, started of safe mode, nothing worked. How do I solve this issue?

Even after numerous Uninstalls and a Reinstalls I keep getting this error notice when trying to open Firefox...

The application was unable to start correctly (0xc0000022)

Running Firefox 125.0.1 on MacOS 14.2.1, all audio input is very quiet for all applications, not just Firefox.

Experiments I ran:

• people can barely hear me in Google Meets
• microphone works great in Quicktime (making a recording) when Firefox is running but not receiving audio input
• microphone is very quiet in Quicktime when running a Google Meet in Firefox
• microphone is very quiet in Quicktime when running a discord voice channel in Firefox
• microphone works great in Quicktime when running Google Meet in Chrome

This started maybe ~3 months ago for me. I'd love to see a fix, since Firefox is my favorite browser in most other ways - otherwise I'll have to give up and switch to Chrome at long last :'(

Firefox Version: 124.0.2 (64 bit) Windows Version: Windows 10 LTSC 2019 (Version 1809)

When I right click the taskbar and press close Firefox, here comes the interface just as the screenshot uploaded. The blue close button doesn't response no matter how I click it and the Firefox's taskbar is flashing yellow. This bug only occurs on the first window of Firefox and only when user right click the taskbar.

It has been a long time for me wishing that some updates would be released soon to fix this issue, while noting happens. Or this bug is only for me?

When I open firefox in ubuntu linux. (WSLg) Fresh install. I can't go to settings in firefox. Steps: press the hamburger menu, press settings, nothing happens.

OS: Ubuntu 22.04.4 LTS on Windows 10 x86_64 Kernel: 5.15.146.1-microsoft-standard-WSL2 Shell: bash 5.1.16

What the title says. While I was doing school work my session crashed and I lost all of my work. Upon reopening Firefox I was told my browser had installed the latest update for Windows. I then checked my crash logs and saw my session had crashed and Firefox had installed the update. Why could have this been? I would like a solution to this to ensure this doesn't haven't happen again. Thanks.

I see my original question is now archived at https://support.mozilla.org/en-US/questions/1380948#question-reply I never closed it because I didn't know if my last process could really fix the issue. It didn't, not always. Over the years, there have been times when the issue would still pop up, but not as often as before (2022 and earlier).

I have a feeling that during an issue, FF is having difficulty setting up shop after starting up. Consequently, it is spending more time before it could become prepared to connect to the Net. I've come up with another "solution," which is deleting (or moving out) xulstore.json in the profile folder after exiting or before starting FF. You can create a batch command or script to execute the process.

So far, FF is connecting immediately after startup.

In firefox Ubuntu (WSLg) the dropdown menus don't work. I have already tried reinstalling both firefox, and the entire OS.

When I press Custom URLs... (see image) nothing happens. This issue is everywhere in the brouwser, on websites, even when I press help in the hamburger menu. (Or settings in that same hamburger menu.)

OS: Ubuntu 22.04.4 LTS on Windows 10 x86_64 Kernel: 5.15.146.1-microsoft-standard-WSL2 Shell: bash 5.1.16

I reinstalled the Visual C++ and Firefox loaded when i ran the Firefox repair but totally locked up. Unable to get to settings or any website and will not run after closing it.
