Firefox slows down when I use web developer tools, I use this whenever I try to save an image on Instagram or other sites that I go to just to save an image or look for the video using the web tools.

Is there a way to fix this issue it lags the browser or it freezes for a second.

Hello, have been scratching my head for a while on this one. Have a freshly setup install of Debian 12, using Sway (wayland) as my Window Manager. I am really struggling with slowness in Firefox, page loads take easily 15 seconds whereas loading the exact same page in another window at the same time with Chromium Debian build has near instantaneous load times. I've tried the following troubleshooting steps: - Created a new firefox profile - Tried "Troubleshooting Mode" in Firefox - Disabled ipv6 in firefox about:config and in Debian - Tried different DNS servers - Tried different non-debian specific builds of Firefox - Tried Firefox Beta and Firefox Nightly for Debian

None of these steps made any difference, and Chromium has continued to be significantly faster. Am really stuck here and would love to get to the bottom of this as Firefox is the only browser that works with a HiDPI display in Sway without blurryness. Happy to provide any and all diagnostics and reports that are needed. Thanks in advance!

EDIT: It seems to be some kind of networking issue, using a VPN solves it. But still doesn't explain why Chromium would behave differently.

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!

Greetings from Maria

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

Whenever I change my VPN (not Mozilla VPN) status, Firefox will refuse to connect for something like 30 seconds then times out, leaving me with a blank screen. I have wait until that interval has passed before I can retry, otherwise it will repeat the freeze. This happens whenever I turn my VPN on/off or switch to a different VPN server. It happens only with Firefox. Chrome and my email client have no problems whatsoever. I think it's some kind of DNS caching problem within Firefox as the problem doesn't happen if I visit a site that I hadn't visited very recently. There's immediate response if I do that. I have DNS over HTTPS and secure DNS turned off in the settings, so it can't be those.

Anyone else have this problem? I wish there was some way to clear Firefox's DNS cache other than having to go into about:networking

Dear Sir or Madam,

I have been having problems with Firefox on my Desktop-PC for about a week now: I am almost always shown another tab with an error message (an new tab with allways the same content) in addition to the website that is regularly called up and also works:

Tab-Headline: Seiten-Ladefehler Fehler: Verbindung fehlgeschlagen

Beim Verbinden mit 0.0.0.1 trat ein Fehler auf.


   Die Website könnte vorübergehend nicht erreichbar sein, versuchen Sie es bitte später nochmals.
   Wenn Sie auch keine andere Website aufrufen können, überprüfen Sie bitte die Netzwerk-/Internetverbindung.
   Wenn Ihr Computer oder Netzwerk von einer Firewall oder einem Proxy geschützt wird, stellen Sie bitte sicher, dass Firefox auf das Internet zugreifen darf.


It doesn't matter which regular website I call up - it also happens when I call up the Mozilla Firefox page.

It is as if my website call is executed twice: once normally and everything is displayed correctly. And once as an extra tab with an alleged page loading error where the connection has failed.

How can I prevent these additional tabs with the error message from constantly popping up and being displayed? I have not made any other settings and Firefox has always worked perfectly so far. It doesn't happen with Google Chrome, for example - so it's not my PC.

Can you help me?

Kind regards Daniela Bohle

I keep getting this message that pops up in a private window to restart to keep using firefox. Everytime I click restart Firefox, it closes my tabs and opens them again. However, 5 minutes later the window pops up again. Even after repeated attempts of updating, even doing a full restart on the computer, Firefox continues to send this window to me. The private window in the bar says about:restartrequired.

I've tried uninstalling Firefox with a fresh install as well as doing a Refresh of Firefox. Neither seem to solve this problem.

Firefox is not permitting videos from YouTube that other browsers easily play. This needs to be fixed. YouTube offers their Premium subscribers videos which can be played at a higher bitrate, which means even 1080p can play at a higher quality. When setting quality on a video, in addition to the 1080p, you can choose "1080p Advanced bitrate" as an option. Firefox has trouble playing these files, whereas Safari and other browsers don't have a problem with YouTube. Please fix this.

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

There isn't a 'create new profile' button. I already made a new profile as well, but it did not fix the problem.

I recently changed to the newest ESR, 115.10.0esr, to fix streaming issues.

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.
