Hi there , I am interested to know if Mozilla support group is aware of the problem Microsoft update KB4474419 causes? I am running widows 7 sp1. I installed the update as you mentioned in your Firefox 100 release notes. After reboot , I got a beep and a black screen - win 7 won't start. I had to find a way to delete the update so I could boot my system back. I asked few of my colleagues that use the same OS and they experienced the exact same problem. Surfing the web , makes it quite clear - this update is faulty and not compatible with win 7 as Microsoft claims. I would like to get a straight answer - can I update my FF99 to FF100 , without the notorious KB4474419 , or , as of FF100 , win7 sp1 is no longer applicable to Firefox ? Thanks. look4

Hiya, So I have used the link below as a guide to get firefox to autoupdate on users computers via GPO.

Firefox is now crashing on multiple Computers, I think they might be crashing while trying to update themselves, as per GPO.

Any help please , crash report attached

I have noticed for the past 3 or 4 updates Firefox refuses to update via Help |About. It tells me there is an update I click on the button on the about page to restart the browser yet the update never installs. The only way to update Firefox is to download the installer from Firefox website.

I have cleared cache and cookies and that has done nothing to solve this issue

I was having the "PRR_END_OF_FILE_ERROR" Secure Connection Error and after going through that whole list of fixes ending with me deleting my firefox account and creating a new one the issue is still happening on sites like youtube after trying to play a video for a bit so i disovered that the two default plugins were giving these messages: OpenH264 Video Codec provided by Cisco Systems, Inc. will be installed shortly", "Widevine Content Decryption Module provided by Google Inc. will be installed shortly." and wont install so at this point I think the final issue I need to solve to 100% fix things is to get these two plugins to finally install but I don't know how to force it to do that

I sometimes receive notification that Fx can't update automatically and I need to download the update. Twice now, the update has deleted my profile on drive D, and replacing it with a new one on the default C: drive. Settings, options, addons all GONE! I finally had to restore my entire system from a backup. What's going on and how can I prevent it happening again?

On Win 10 / Firefox 91.0 I keep getting a popup saying I need to update FF with options to download or dismiss. When I go to "about FF" I am told I am current. This occurs about once a day no matter which option I choose. I have restarted FF several times for other reasons but the popup still occurs frequently.

I keep getting the message "update failed. reason unknow" and always have to install updates manually despite my settings (see attachments). How can I get Firefox to update automatically?

Support page indicated e-mail migration from Outlook had to be in Version 31.8, then allow Thunderbird to automatically update to latest version. Successfully completed migration to version 31.8, however the About Thunderbird window states that "Thunderbird is up to date" and "You are currently on the release update channel." It does not automatically update to anything.

Alternatively tried changing profile pointing, also moving Local Folders mail to profile folder for updated version 91.4.1 also installed on computer without success.

Any way to convince 31.8 to update?

The feedback page is useless and I don't see any way to contact Mozilla so this will probably go unviewed and be more of a rant but Firefox absolutely needs a much better profile management and back system. Particularly there should be a mandatory step to backup a current profile before updating. Today I updated Firefox not by choice, for some reason my PC decided that a single click was a double click. So the latest version created a brand new profile I assume because I already had Firefox open. I am beyond rage right now because I just spent the last half hour trying to find my correct profile in my user data because for some insane reason Firefox decided to create two new profiles.

I manually backed up my profile data but it's incredibly stupid that A) the profile naming is gibberish and B) I had to do that in the first place.8

I just updated Firefox to latest version and cannot run it on my current OS. How can I get back to the older version I was using until I'm able to upgrade my OS? As it stands I cannot access Firefox on my Mac. The icon has a big do not enter cross on it. Please help. Fast. Thanks.

I just allowed an update to my computer from Mozilla called software updater and now I can't use duckduckgo to search the web. I had to use google to get to this page for help. Let me know right away how to remove the mozilla updater from my computer and get back to the firefox browser that works. This is interfering with my web searches and banking. This is extremely urgent.

I was using one of the old Firefox ESR versions (can't remember exactly which) because I was still on an old Mac OS version, 10.9 to be more specific.

I recently updated to macOS Sierra 10.12.6 and as a result, as soon as I opened Firefox, I went to check if it would update on its own and it did. It updated to version 91.6.0 esr. After this update, something weird happened: the browser won't load any page.

I checked, it's not an internet connection, because other browsers are working normally. It won't load any extensions either. So I want to fix this issue with an update.

The question is this: I remember installing what was called Firefox Quantum. As of now, the name on the about section is just Firefox Browser, maybe because of the updates. • Can I install the latest "regular" Firefox 97.0 on top of the this old installation, just using a standalone dmg file? • Will this installation preserve everything that's already in the browser? By everything I mean bookmarks, extensions, history, cookies, etc.

It seems to me that the automatic updater isn't installing version 97.0 on its own because it's coming from the ESR versions. So it's stopped at 91.6.0 esr.

Thanks in advance

We use Firefox ESR in our enterprise and have been using 32bit for a very long time even though we have all Windows 64 bit OSs, we are now attempting to move from Firefox 68.x ESR 32bit to Firefox 78.x ESR 64bit. The issue we are seeing is the Firefox profile does not automatically get picked up after the upgrade has taken place, our process is to uninstall the previous version and then install the new version. We know we can recover the profile by opening the browser and going to about:profiles but asking a user community or thousands makes it a little difficult on our end user support. Is there a way to automate the profile move during the upgrade of the browser in this scenario? Also not that a lot of our users have more than one profile in thier user folder so if there is an automated way of doing this how can we tell which profile is their current default profile?

Hello I have a second computer network that has hotspot enabled. For Mozilla browser to be updated automatically without the need for a hotspot username and password. The IP and address of the sites related to the Mozilla browser update must be entered in the walled Garden of the MikroTik router. Please help.
