Появилась какая то адресная строка наверху экрана поверх других окон, как убрать? (Не уверен, что это проблема именно браузера, но ИИ сказал, что это из-за Firefox)

Since my last FF update (140.0.1), every time i open FF it asks me to set FF as my default browser. But when i click the link, the choose default browser does not show FF as an option, just Google Chrome or Internet Explorer. How do i set FF as my default browser? Thanks. I'm using Win10 ver 22H2 19045.6809 on an Asus laptop, if that has any bearing.

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 :))

My cloud account is nearly full but when I go to update the account or purchase more space I am blocked. The authenticity of going from Mozilla Firefox to cloud is blocked because it cannot confirm it identity. I at the point of not being able to use my computor due to being blocked. Can anuone tell me how to get through?????

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.

The problem seems to have started after a browser update. Running up-to-date Windows 10. This issue does not occur when using Edge. Youtube videos are blank (spinning). Sometimes it results is a still frame, other times it spins forever. Many times, you can see a series of stills in the video as the time line is dragged from the beginning to the end of the video. A small number of videos will work, but I have not been able to predict which will work or why. A different Win 10 machine on the same network is fine. I have tried all of the solutions I could find searching on-line (clearing cache, cookies, reboot, restart, update browser software, etc, multiple times). Checked settings in windows, firefox and youtube looking for something. Any help would be appreciated. Have used Firefox for decades and I don't want to be forced to change browsers.

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.

I just read a PC World article concerning extensions containing malware. AdBlock was listed and I've been using the extension for some time. Are you aware of this issue? Is the extension available viz Firefox setting/extensions in question. Should I remove it?
