I had to restart my Mac. When TB restarted during relaunch of the Mac, it was like TB starting fresh. It didn't display my email accounts, or my folders with saved emails, etc.

I quit TB and looked for it in my Applications folder - and I found two versions of TB. Inside the Thunderbird folder was version 140.9.0esr. Outside the Thunderbird folder was version 150.0. See attached screen grab.

I thought I should try launching the newer version (which was outside the folder). So I moved the 140.9.0 version to the trash, then launched the newer version – and it had the same problem. It looked like I was starting TB from scratch.

Next I quit TB (the newer version) and moved the older version out of the trash and back into the TB folder and double-clicked on it. A dialog box popped up saying that the file is damaged and can't be launched.

So I tried launching the newer version again, and it still looks like starting from scratch.

I really hope somebody can help me solve this. I can't access any of my email accounts or any of my stored emails. I use email for work (as most of us do), so this is crippling me.

Thanks in advance for any help.

I am a TD Bank customer who uses their Bill Pay feature. A recent FireFox update now prevents me from completing my payment sequence. Please alert me how this can be fixed. I like the FireFox browser but will remove it from my computer if no fix is offered. When I use Google Crome I have no problem completing my payment sequence. Thank you.

I am having to download Foxfire Developer Edition for a course that I am taking, but I am unable to figure out to go this. There is not enough information on the internet to get this done. I have watched videos on YouTube, but they are not helpful. I am new to this and would like some guidance in the matter.

We are in an enterprise environment and for years we have had disabled automatic updates.

Firefox ESR 128.2.0 has been deployed with defaults and these settings have been configured to override previous settings.

Computer Configuration > Administrative Templates > Mozilla > Firefox

- Custom Update URL = Disabled
- Disable Update = Disable
- Application Autoupdate = Enabled
- Background updater = Enabled

We also have a system proxy configured.

Updates do work if someone goes to Help > About Firefox.

Looks like the update interval is once every 7 hours but how is this triggered?

Dear friends, I recently realized that Mozilla Firefox does not support Windows 7. At the same time you want people to prefer your browser. Why did you stop supporting Windows 7. I think that window 7 is an OS used from thousands of users. I prefer to use this OS and Linux Mint. So, I do not understand your policy not to support this OS. Thank you in advance for your answer!

I worked with an IT guy to help me transfer information from Carbonite back to Thunderbird. I can see all the files download to my computer but can't get them and the address book to update. Does anyone know someone who specializes in helping people with Thunderbird issues?

hello.

I had the to try to open Firefox, to do something, but you showed me this message: 

error platform version 130.0.1 is not compatible with min version >=130.0 max version <=130.0 what do you suppose me, to do now?

For the past month or two, at random times when I open Firefox, I see a message stating, "Looks like you reinstalled Firefox." To be clear I have not uninstalled Firefox in any instance where this message has been displayed.

When this happens, I’m unable to browse the web. To resolve the issue, I have to remove the uBlock Origin extension and reinstall it. Once I’ve done that, browsing returns to normal. However, I then need to reconfigure my filters and adjust settings within FireFox

I’ve tried uninstalling and reinstalling Firefox to see if that would prevent this issue, but it hasn’t worked.

This problem is specific to my PC—it has never occurred on my MacBook.

Any assistance in understanding why this happens and how to prevent it would be greatly appreciated.

Thank you.

I have been unable to complete the update/upgrade of Firefox on my Laptop. Upon starting my computer I have downloaded the upgrade file offered in the opening message. It performs normally right up to the end when it gives a message that something went wrong. It then offers an alternate download and method to upgrade which downloads fine and begins to install. At the end of this install, the install wizard says "finished" however despite the "Launch Firefox" box is checked, it never opens Firefox. For some reason the update is not completing, and now I am having trouble with some Apps opening which I suspect is due to the browser being out of date. I have tried clearing my Cache and Cookies and re-trying but have remained unsuccessful. I really could use some assistance with getting my browser successfully updated. Best Regards, Brian

For some reason fire fox will not download for me to install on my iMac. I have been trying multiple ways to get it to down load. It simply stops midstream and will not finish so that I can install on my iMac. IOS is Monteray.

I am running W11, and use Thunderbird and Firefox, with Dudk Duck Go, but since downloading TB139.0.2 TB has become schizophrenic If I click on the TB con,the latest version of TB displays and I find it difficult to negotiate. But if I double click on that icon the older version of TB loads and seems to work OK

I had trouble with Thunderbird being slowwwww, so I uninstalled and have been trying to reinstall but now I get warnings that it can't complete the installation. The images show the pop ups I get about something not being right.

I am trying to upgrade from ESR to Release. I saved my profile successfully, went to the install page and clicked Download. Got a request to donate, which I did. Then I got a page saying Thank you, Finish installing and enjoy Thunderbird. But there is no way to finish installing and I never got a download file. I've tried multiple times, nothing happens. Help!
