There have been some strange problems since I totally uninstalled a Firefox ESR version, and went back to the normal versions. That ESR version is still showing up in the registry in odd places as if it has not been uninstalled: Firefox-308045B0AF4A39CB

I'm wondering if it is causing problems, because when I made it the default browser, it seemed microsoft started using it in some of the ways it ordinarily uses Edge, which is why I do not use Edge.

I do NOT want a browser to access or control my desktop or anything else on my computer. I simply want to use it as a browser.

At least there is no longer "your browser is being managed by your organization" showing up (because I designated no update. I prefer to choose to update manually. Because I do not always have time to reconfigure the screwups updates cause because of changes made. Firefox is not as bad as microsoft . . . yet, but unsuspecting updates always create time some type of configuration issues that require time.

Recently, I fully uninstalled the ESR version, and returned to a fully installed regular version. It was 155, but suddenly with a few days it was 158, then an auto update to 159. I made sure to download the Firefox full version, NOT the microsoft store version. However there was already one automatic update without notification, and I had selected no update without my confirmation. So I am wondering if the update/download was the microsoft store version that screwed up my compute configuration, again, because microsoft settings is no longer working. And even though everything was uninstalled from the ESR version, including in the registry (I did a search and removed what was left) and after a day or two there were no more of the ESR version entries. So it seems to have been fully uninstalled.

Since then there was an auto update to 159 which I did not know until the configuration changed, so I checked the version. Since that time I see that entries for Firefox- (the ESR version are back in my registry) even though I was able to fully uninstall everything. But it only lasted until the update.

Is it no longer possible to be informed there is an update, and choose whether or not to update at the time. I do not trust the update will not be the microsoft version, so that means I must do an update via a full install that I download myself and know it is not the Microsoft version.

I am not exactly sure what microsoft does differently with it's update. But it seems to connect the browser to a desktop shell. I am wondering if the problems from microsoft start when I select Firefox as the default browsers - which cause the microsoft update version to make Firefox a startup shell, the way it uses Edge to be a startup shell

So basically, I'm wondering if a microsoft update of Firefox has screwed up my microsoft settings again, because Microsoft Settings is no longer working. And two days ago I got this error message when trying to access Microsoft Settings: all ms-settings are showing up class no registered ms-settings:defaultapps?registeredAppMachine=Firefox-308045B0AF4A39CB class not registered

I asked in the past how to prevent getting the microsoft version of the Firefox update and there was no response. So I changed to ESR. (Then the bank need an updated version of the browser to connect properly without problems, so I changed back to the regular version.) Surely other folks have had a similar problems and want the Microsoft interferring with Firefox updates..

I cant log into f1.com. tried using Chrome and got in. This is getting tiresome.-

There is also a few other things not working, but lets start with this.

Hi Mozilla Support,

I made a boo boo, was half asleep trying to shut down and wanted to quickly save a set of browser tabs to come back to later, so "attempted" to create a folder to save within a nested structure in my bookmarks library (using Ctrl+Shift+O editor). I right clicked and intended to hit 'f' for new folder in the structure, hit 'd' instead (delete). This was on an upper level folder structure of thousands (10's of thousands....?) of bookmarks.

Realised my half asleep mistake and doubled down! Hit Ctrl+Z to undo changes.

Well, I guess FF was struggling to process all of the changes, then got confused with the undo, and broke without performing either... F**K. But ok, I will just restore from a backup, I have those setup.

So I went to 'Import/Backup -> Restore, and picked the latest date. Okayed the warning and waited. It failed, gracelessly, by deleting all my bookmarks, then errored. "Unable to process the backup file." Now I can't restore any of the restore files in the list. The latest one looks broken with almost no data, but all of the earlier ones are there, they exist in the folder structure under AppData, say they have 30,000+ bookmarks, and are all around the 20MB size.

None of these restore.

My only hard HTML backup is from early in the year, March, and that is very old in my activity levels.

Also, why are all of the json files failing?

I've since restarted my PC, slept and come back to the problem awake. Still same problems.

I have gone as far as using the 'Refresh' technique in the uninstall options, and despite everything else coming back from scratch, I still cannot restore my json backup files. They all give the same warning, delete any bookmarks I have added and then error with, "Unable to process the backup file."

Is this something that has happened before? I get I screwed something up, but what could be preventing this from restoring? Are all of the json files now poisoned somehow?

Do I have to do a full uninstall and reinstall and try again? And if that fails, what are my options?

I have backups for a reason, this very reason in fact, so that when I error, I don't delete my life...

Would love some guidance on this, if there is a way to check .json integrity, or anything else pertinent I might have missed, I would appreciate a poke in the right direction.

I have downloaded multiple versions of firefox, and when I browse to a site, the response is: MUST ENABLE JAVASCRIPT. I am 81 yo and get confused as to how accomplish this. Please advise!

I've been trying to get the browser toolbox window to work correctly for a couple of days now and I can't figure out what's going on. When I invoke the toolbox window with the shortcut key or through the menu entry the window pops up and asks for permission to connect (I click 'ok' in this box) but the window gets stuck before loading the toolbox ui, screenshot of what I'm seeing is attached.

I'm on windows 11 pro 25h2 and firefox 159.0.

I should note that this is the same behavior in a clean temp profile in firefox, as well as the same behavior in other firefox based browser, such as librewolf.

Does anyone here know what I can do to get this working?

Thanks for any help and let me know if you need any other info.

Two days ago I started getting notifications from Firefox on my laptop about text messages received on my android phone. This has never happened before and I made no changes I can remember. Tell me how to fix it. There are too many better browsers for me to deal with this crap

Hi, I’m having a problem when I turn off the screen in Windows 11 26H2. The latest version of Firefox minimises the window to a small window, even though it was in full-screen mode before the screen went to sleep.
