Firefox Community Forum

Hi, a while ago I have set my browser homepage to have links to recently visited sites and pages and I had set a background too, but a few days ago it suddenly seemed to forget about all my search history and settings for some reason, as you can see in the screenshot below. This behavior does not happen with any other part/functionality of the browser. I don't really know what could be going on, so I'm reaching out here.

Recently Mint upgraded my FF to v147 - possibly relevant, possibly not. There's no post mentioning anyone having this issue on the Mint forum though.

In my Settings, "Open previous windows and tabs" is definitely enabled, but it doesn't happen. I only get my homepage custom URLs.

I went into troubleshooting mode and FF then behaves.

So I figured the issue must be with an extension - but I disabled all my extensions, and it doesn't help. Only going full troubleshooting mode fixes it.

What do I do next please?

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 :))

Dear

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?????

ホームページにヤフージャパン以外にいくつかのページを設定しています。 ヤフーを見ているときにホームボタンでトップページにもどると他のタグのページも全てまた新しく立ち上がってどんどんタグが増えてしまいます。 見ているページだけ初期化する設定に出来ませんか。 Microsoft　edgeは出来たのですが、出来ればfirefoxに乗り換えたいです。

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.
