Firefox was using GOBS of CPU, so I killed the master process and relaunched, but after launch I couldn't get any pages to finish loading. I then hoped to copy URLs from tabs and paste them into Floorp (which is working fine, as is Chrome), but I couldn't even snag the URLs (dominated by YouTube pages). I ran a full-system virus scan, finding nothing. The most recent Windows-11 update on 2026-Jan-15 isn't recent enough to be a likely causal factor. Firefox has about twice as many extensions as Floorp, but it was running fine until late yesterday (it's now after 3AM). I couldn't get the extensions page to load, so I've attached a screenshot of C:\Users\Mike2\AppData\Roaming\Mozilla\Firefox\Profiles\oa7ou5xk.default-release-1715337056307\extensions There are several other profiles, but there's very little in them (one profile with a times.json & several profiles containing a parent.lock file)

Processor Intel Core i9-9980HK CPU @ 2.40GHz (2.40 GHz) Installed RAM 128 GB System type 64-bit operating system, x64-based processor MSI GT75 Titan 9SG

If I reinstall, will I lose all of my tabs?

I’m noticing a strange performance issue with my website: Wildiferemovalpro

On Chrome and Safari, it loads perfectly fine. However, when I try to open it in Firefox, the loading spinner just keeps going, and the "Time to Interactive" feels significantly longer.

I’ve already tried:

Clearing my Firefox cache.

Disabling my extensions.

Checking on different machines.

Is anyone else seeing this? I suspect it might be a script or a specific CSS rendering issue unique to the Gecko engine. Would love it if someone could take a quick look and let me know if they see any red flags in the console.

Hallo beisammen,

bei Favoriten (alle Tabs) speichern fällt mir jetzt erst auf, dass die Tabs, die ich in Sammulungen zusammengestellt habe, nicht mit gespeichert sind. Dadurch sind jetzt nach einem massiven Absturz von Mozilla genau diese Tabs nicht zu finden, das habe ich beim Speichern nicht bemerkt. Kann ich da jetzt dennoch irgendwie drankommen? Über andere Wege, auch das Prozedere mit sessionstore/recovery, hat es nicht geklappt (und synch. mache ich bewusst nicht).

Für die Zukunft beim Abspeichern aller Tabs als Favriten - muss ich alle Sammlungen öffnen, damit es alle in den Ordner aufnimmt?

Danke für guten Rat :))

I find a website I like, I add to bookmarks, chose a location, add some tags and save.

Next I look for bookmark to verify it saved and it is not in folder it was saved into.

I open Bookmarks and search for this newly created bookmark and it is not in the correct location, it is in another folder, or past the folder in a tree that is not seen under the drop-down up under address bar, only through searching via Bookmarks. After I searched and I had found it, I chose open in folder, saw its position and dragged it to the folder and position I wanted it to be, then close the search, use the drop down folders in bookmark bar and not there. ??

Go back to Bookmark search, find it and it is shown to be where I last dragged it, but it is not there unless I search for it.

So not sure what is going on with bookmarks, but after saving they are not saved where I directed them to save and I am losing my bookmarks to some void in my bookmark manager.

Right now, when I open firefox up, I ALWAYS get the pop that a download was stopped because of a virus and it's really annoying that I have to dismiss it EVERY SINGLE TIME even though I remove it from downloads and clear history. How do I even stop this from happening???

EDIT: Even setting browser.download.alwaysOpenPanel to false does NOTHING so I have NO IDEA what to do.

Steps to Reproduce: 1. Launch Firefox (and add Sites shortcuts) 2. Do not navigate to any website 3. Observe network activity using Process Monitor or clash verge

Expected Behavior: - Opening about:home should not establish TCP connections to remote sites unless the user interacts with them.

Actual Behavior: - TCP connections are observed immediately to sites listed in Top Sites shortcuts, even without user interaction.

Notes: - Disabling DNS prefetch, speculative preconnect, and predictor settings does not prevent these connections. - Extensions have been ruled out, I can distinguish darkreader.org(extention) mozilla.org(update) and reddit.com(your sponsor url) from *.edu.*(my shortcuts), DON'T mention that. - Connections occur before any page navigation or clicks. - I suspect that Firefox may attempt to load site icons (favicon / tile thumbnails), but this is unconfirmed.

Attn: Customer Support

  Firefox is currently my "default" browser.  I am running the most current updated Firefox browser.  I am using a desktop iMac with OS of Tahoe 26.1     
  It appears since the latest few updates (on Firefox) over the last week or so, I can no longer log in to my online banking.  I am able to enter my username and password (I'm using the 1Password app on this desktop and my iOS).  After entering my username and password, the progress wheel just spins and spins and nothing further happens.  The screen just sits there and does not progress to the next webpage allowing entry to my banking.  I know that it is a problem with the Firefox browser.   When I log in to my online banking using Chrome, I have no issues, it logs right in.  
  What is going on?   Please advise.  I'm thinking about ditching Firefox and going with Chrome or Safari.

Thanks for your assistance Dennis Ontario, Canada
