I've been using TB on 2 of my smaller email accounts for several months and really like the way it operates. I'm nearly ready to add my main email account (web-based Outlook) to TB but have one final question. If I add the account to TB, give it a fair try, and just don't like the results, can I simply delete that account from TB and go back to accessing it via its website? I have confirmed that POP is disabled for my Outlook account so I understand all email remains on the server until I remove it. I also understand TB would leave the email from the account on the same server, again pending some action I might take to remove it. So it would seem that I could delete the account from TB and revert to web-based access for the account, just as I'm doing now, and the folders and saved emails would still be there. Am I overlooking anything?

I have Firefox 124.0.2 running on Windows 11. For some reason, I can't update Firefox. When I manually download 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?

Originally reported on April 11th /questions/1444593: I have Windows 11 and the Firefox 124.0.2 browser. I cannot update to the latest version of Firefox. I receive an error message "Failed to update". I've uninstalled and reinstalled the browser, ran the install utility selecting update, nothing seems to work. Please help

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

Hello, I have problem with firefox. When I try download from facebook page files .docx, .xlsx (Microsoft Office) Firefox automatically download it as PDF and file is broken. I don't know how to repair this. Please help, it is very frustrating.

Prior to update 125.0.1 corporate intranet users could download PDF files from our Line of Business applications / Webpages. Today after the latest update the PDF files download but are corrupted. The site was added to the trusted webpage without improvement.

Adobe Acrobat Reader could not open ********.pdf because it is either not a supported file or because the file has been damaged

Hello all together,

i just reinstalled my whole pc, win10 64. I exported my profile including all possible data, the .zip was too big to import so i copied it into the profile folder, on my desktop, in another foldet etc. But i always get the error message shown in the picture. This is my only chance to have access to my (partly) old email accounts... that's why i followed all steps, but i cannot import everything. I REALLY need your help and would appreciate it A LOT.

Thank you in advance!

Hi! On the latest version Mozilla Firefox 125.0.1 when i download .docx files i get the message 'File not downloaded: Potential security risk.' I select Allow download and the file downloaded can't be opened.

Thanks!

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?

Recently Firefox always has the error "failed to check for update". I have tried restarting my pc and running as admin. I am on windows 10.

I have been able to manually install the latest version by installing it over the top of my current install, how can I fix the error to be sure that my browser will auto update?

Thanks

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...!

Hello,

When I go to update Firefox through the settings > general > firefox updates > check for updates, I am getting the error in the title. I can manually download the app installer and update to the most current version which is what I did for version 125.0.1, yesterday.

I have tried uninstalling and reinstalling firefox, installing the beta branch, refreshing firefox, running in troubleshooting mode, completely deleting all user firefox files, and I still get the error. No DNS resolver issues to the update server. No firewall issues. No network blocking (tested with other devices).

This issue started after March update to 124.0.1 and continues to current stable release 125.0.1.

This issue also seems to extend to checking for extension updates.

Below are browser logs for when i try to check for update or update extensions.

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!
