I have uninstalled and reinstalled firefox and restarted my computer but it still will not load. When i first reinstall it it comes up but will not connect to the intenet.

I see my original question is now archived at https://support.mozilla.org/en-US/questions/1380948#question-reply I never closed it because I didn't know if my last process could really fix the issue. It didn't, not always. Over the years, there have been times when the issue would still pop up, but not as often as before (2022 and earlier).

I have a feeling that during an issue, FF is having difficulty setting up shop after starting up. Consequently, it is spending more time before it could become prepared to connect to the Net. I've come up with another "solution," which is deleting (or moving out) xulstore.json in the profile folder after exiting or before starting FF. You can create a batch command or script to execute the process.

So far, FF is connecting immediately after startup.

About a week ago I started getting these update error messages stating "Update available - Firefox couldn't update automatically. Download the new version". I've also tried clicking "learn more" on the error message but it's a dead link. Going into the settings for updates I am set to auto update, but when I manually check for updates it says "Failed to check for updates".

The help article on this issue simply tells you to download and manually reinstall Firefox, but I'm having to do this nearly every day. I work in IT myself so I know a "bandaid" workaround when I see one. Is there a solution to this issue?

I'm using the OneTab add-on, Enabled. The icon no longer shows on the Toolbar, though it is on the Menu bar next to Firefox View.

I ran Remove and then Added it again, hoping the Toolbar Icon would reappear = no go, And I lost all URLs already saved, stupid me. To be clear, clicking the Icon on the Toolbar saves all open tabs.

Is there a fix via Preferences? Thanks. gw

After just turning on my computer running Windows 10, I opened Firefox. I open 1 web site and noticed my computer showed a (16) prefix when loading Firefox. I opened the Task Manager and it showed that there were 15 instances of "firefox" running in the background. All showed a UAC Virtulization of "Disabled". But they also showed using 638.8MB of memory. I do not know whether these are necessary files that must run in the background or if the number of files indicates that my system has been hacked and someone else is in my system from outside. Any suggestions as to validity of these files running or how I might confirm that they should be running. I have noticed the number of excessive background files before but the number is never consistent which makes me fear I may have been hacked.

something apparently got corrupted in firefox.. i tried running update and i keep getting failed to update.. i have refreshed.. i have uninstalled and reinstalled ...nothing. i am sure there is a folder or file somewhere that is corrupted and i cannnot find it. because even when i uninstall and reinstall fresh. all my bookmarks are there .. how to i start a TRUE NEW install??

I did an Upgrade to a version of Firefox that would bypass those "Your Browser Is Not Supported" messages that apparently come from "Cloud-flare." I figured [naievely!] that my addons would "port" to the upgrade. They didn't. Is there any way [e.g., a putative backup file, perhaps] that would allow this?

Thanks in advance...!

I'm using the latest version of THUNDERBIRD for WINDOWS (now 10 HOME), but this problem has existed for years with previous versions of THUNDERBIRD and former releases of WINDOWS, both HOME & PRO releases. And, it seems to be very specific.

 When i receive e-mails from (especially) 2 friends who both use AOL as their e-mail client, when I receive them, the imaged files (or memes) are always 'converted into attachments, and what shows in the Body Text of the e-mails is empty boxes.  Yet, when I get e-mails from others, including from commercial sources, if there are images within the Body Text, they are present there. This IS very annoying because many times the e-mails I get from these two friends are technical e-mails, with clarifying images as part of the Body Text.
 When I have mentioned this to them, their responses are that n one else complains, only me, and so the problem MUST BE at my end, but that doesn't make sense, since when I receive e-mails from others (Gmail, etal.) any included images are fully where they belong.

++++++++++++++++++++

 Secondly, WHY is it that when there are threaded e-mails in the Sent folder, the ARROW to expand the thread appears at the left side, but in the Delete folder the ARROW appears between the title of the e-mail & the next column?  This IS very annoying!!!!

Also, when I'm in the DELETE folder, sometimes only two options appear at the right side: Archive Delete, BUT in other incidences, there's a plethora of alternative options, and the Delete option is positioned in a different place. More often than not, I click on the option to send it e-mail to the Archive folder, when I really wanted to Delete it permanently. Another major annoyance!!!! Thank you robert herold

We have a ministry known as ECAM (it's an acronym).. How can I filter on subject lines without also getting every subject containing the word became?

As a longtime user and a regular subscriber to Mozilla, I can’t get access to Thunderbird. Reason is that I had to repair the hard drive and now I am locked out. I am unable to insert a master password because I never had one. Reason being that I have used Thunderbird for years and years before that was required. To say I am frustrated is an understatement. None of your automated advice has a remedy. Should I install a new version of Thunderbird and begin afresh? John Cotterell ( an Australian supporter of your project)

I can receive emails to my (protonmail.com server) email account on Thunderbird. But I cannot send emails. This is the error message. "Sending of the message failed. An error occurred while sending mail. The mail server responded: Error: no such user. Please check the message and try again."

Thank you for your help!

I have Firefox 124.0.2 running on Windows 11. For some reason, I can't update Firefox. When I manually down load the update file, it appears to run Ok, but the version doesn't change. If I go to settings and click on "Check for Updates" is comes back and says Failed to Check for Updates. How do I fix this?

It has been observed that when a user uses the Firefox browser and tries to download a DDD file, the file format is .pdf instead of .ddd. In the devtools, it was observed that the content-type is text/plain in the response to the request. I changed the content-type to application/octet-stream, but the error still persists

Nothing happens when I press the play, like, dislike, notifications, favorite, or join server buttons. On top of this, when I try to open the catalogue it's just a grey screen with nothing in it. In the attached GIF I am clicking rapidly. I don't believe this is an issue with roblox itself, as when I open chrome everything works perfectly. The only extensions I am using for the site are RoPro and BTRoblox. I have tried to turn the extensions off and have even uninstalled them, however the problem was still not fixed.

I have Windows 11 and Firefox 124.0.2. Firefox keeps asking to reinstall. I think it is because I keep getting the message that it fails to check for updates. I don't know if I have installed the Microsoft Firefox or the direct Mozilla Firefox downloaded. Maybe that is the problem, but I am not tech savvy. I have used Firefox for many years and like it. I am also too old (83) to deal with these problems. Help!

"Hi there! I've been experiencing some difficulties with the Mozilla Firefox mobile browser on my Android device. Whenever I try to open certain websites, the browser crashes unexpectedly. I've tried clearing the cache and reinstalling the app, but the issue persists. Could you please provide some guidance on how to troubleshoot this issue or any possible fixes? Thanks in advance for your help!"
