(I am a Chinese and English is not my native language, so please forgive my grammar or vocabulary errors) I was doing my programing test in class and the Tab Edit profile pop up, at the same time the theme of my browser changed. I didn`t want that changing so I clicked the Delete button. In the following few seconds nothing happened so I just put it aside and continued my examination (it was on a website and I need to sign in). And then suddenly, my browser was closed. When I opened it again, it didn`t recover any of my tabs. I tried to open my previous tabs and found that my history was empty, and when I returned to my examination and try to login, I found that even my passwords were all deleted. What was happened? how to recover my tabs and my passwords? I just don`t want to change my Theme why every thing was deleted? (and also, why Support service in Chinese is not available?)

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 mainly use my second business account for google docs, yet whenever i search docs, I get docs.google.com/ (which leads to google docs on my personal account) as my recommendation, while I want to be recommended docs.google.com/document/u/1/

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..
