I've uninstalled Firefox and reinstalled it and cleared the cache. And it's still either not linking to certain sites at all or not, opening them correctly or completely. I don't wanna spend any more time than necessary on this since i've tried various ways to fix the issue.. If you can help me, that would be great. I guess I could use chrome, but I have used firefox for years.And as a rule, haven't had any problems up until now.

Suspected sessionstore.jsonlz4 corruption possible Sync rollback conflicts -

Please direct post to Sumo forum including jscher2000 or like-minded wizards.  Chat takes you down a never-ending rabbit hole.   Sync rollback conflicts - extremely large tab sessions spontaneous restoration of previously closed tabs during live browsing

Read several different instructions on Chatgpt that takes you down a never-ending rabbit hole. Firefox is restoring previously closed tabs from days or weeks earlier without user input during active use while typing in the middle of the keyboard with an activated red stylus mouse - used frequently and/or with an external mouse. The thumb pad is turned off. There are no shift, windows, 7 strokes. Upon restart of the computer, the Firefox settings are set to restore only active tabs open from previous session. This is a Lenovo T16 Thinkpad product no. 21HH003yus. The issue appears to be related to session restore corruption, possibly triggered by very large tab volumes (hundreds of tabs). Windows 11 that tabs reopen during active typing (not startup) hundreds of tabs open whether Firefox Sync is enabled ???? whether crashes/freezes occur - no whether the same old tabs repeatedly resurrect - no, but there are so many of them from weeks and months ago. whether you use session/tab extensions  ??? Believe recent version of Firefox or close.

Help please direct post to Sumo forum including jscher2000 or like-minded wizards familiar with suspected sessionstore.jsonlz4 corruption issues. Thanks so much!

My passwords have been randomly disappearing from my PC. My android has the passwords intact but it will not sync in either direction. I have followed every instruction that I can find with no success.

On a couple of occasions, a successful sync has happened randomly a couple of days later.

On this occasion no syncing so far. (two days)

I am feeling that Firefox is becoming somewhat unstable, which is a shame as I have been using the browser since Noah was a lad.

Any ideas?

Hello I have reinstalled my firefox on a new reinstall of windows 10 as my older version 10 crashed and went to the wall. however I have all my tabs and fafourites up and running but when i try and download my paid version of Nord VPN firefox comes back and says its not secure and wont load the website ? this has been working for me in the past. any advise would be greatfully accepted. thank you.

I’ve been testing how different browsers handle redirects and external triggers from game-related tools, and I’ve noticed something odd with firefox. When trying to launch certain experiences or apply custom settings from external links, firefox doesn’t always behave the same way as chrome or edge—it sometimes blocks or ignores the flag triggers completely.

for example, I’ve been working with a roblox-related launcher that uses something like a fast flag through bootsrap to customize the client experience. everything works smoothly in edge, but firefox seems to either strip the flags or block the redirect entirely.

is there a setting I should look into that might be interfering with these calls? could enhanced tracking protection or strict HTTPS enforcement be playing a role?

would appreciate some help....

Just this week firefox has been demanding that I choose a profile before I gain access. Can I skip this step? And how can I change the unpleasant blob that I must choose. I have got one answer which requests a screen shot but I can't find my question to attach it. (I can't find the old search questions--but I'm most elderly.) and need links or reminders. Anyway, I'll put the screen shot here.
