Firefox 社群討論區

I've been prompted to update Firefox. Multiple times I have downloaded the latest version, deleted the existing one, and installed the latest one. The next day I get the same prompt that I'm in need of an update.

I rebooted Windows. Firefox seems to have been updated. But a firefox installer was downoaded. This behaviour is stange an suspect. Do I have to re-installa firefox? Why?

I have been running version 147.0.2 on Windows 10 Pro. I manually downloaded the version 147.0.3 updater and ran it without any apparent problem. However, when doing the required restart, the update process did not complete. Multiple restarts and cold boots have not remedied this. When I start Firefox using my desktop icon, version 147.0.2 is started.

My "Programs and Features" window shows both versions are installed. When trying to uninstall either version, in either order, I receive a message saying that the system should be restarted to complete the update process. As stated, this does not work.

Following a restart, the Performance Monitor does not show any recognizable "ghost" processes that would need to be stopped.

Inspection of the System event log showed the following Warning:

 *  Name resolution for the name push.services.mozilla.com timed out after none of the configured DNS servers responded.

There may be other warnings / errors that are pertinent to this situation, but that was the only one that mentioned "mozilla" or "firefox" by name.

Every few weeks I get this error and my bookmarks and passwords are corrupted. I have uninstalled and reinstalled Firefox, per the full uninstall instructions, including deleting old Firefox folders and it works for awhile and then returns.

Error: Platform version '147.0.3' is not compatible with minVersion › = 147.0.2 maxVersion < = 147.0.2 Maybe try to reinstall Firefox?

I want to upload the current version of Firefox. However, the system Administrator (who is me) will mnot allow me to do so. How do I change settings to allow for the upload.

When I open FF I get the message "Update available. FF couldn't update automatically. Download the new version - you won't lose saved information or customizations. < download > < dismiss >." When I click "help > about", the message box says I'm on the latest version of FF for my Windows 7 computer, 115.32.0esr (32-bit). I understand I need a new computer and that Mozilla isn't providing more updates to those of us left behind. However, I don't recall ever getting messages telling me to download a version when there wasn't an update that I could actually install on my current hardware and OS. Am I missing something by not doing the download to which reference is being made in the cited recurrent message? Can I expect to get this non-actionable "Update available" message from now on? Regards, Long time FF user, dwy

Firefox requested helper tool to download after an update & now it will not perform the helper tool to install and Firefox is not responsive and doesn’t start up. I’ve uninstalled it 2x and it will work for a few days then the helper tool install request pops up and the cycle starts over.

The task name is:

• "Firefox Default Browser Agent 308046B0AF4A39CB"

It runs at 10:07 every day. The command line from task scheduler is:

• C:\Program Files\Mozilla Firefox\default-browser-agent.exe

Command Line Arguments:

• do-task "308046B0AF4A39CB"

It reports that the version of the browser is wrong and that my profile was used with a later version of Firefox. But everything works just fine so how do I fix this error?

On 2026-04-15 from about 10:00 CDT on, I have not been able to update Nightly nor Firefox Developer Edition (Aurora). Both of them notify me that there is an update available, and when I click on Help -> About Firefox I get the usual panel that gives me the update ID to click on. Clicking on it tells me it's Downloading Update -- 0 bytes, and it never flashes the expected size of the update, never shows progress, and never completes. It seems to be acting as if the update server is out of commission.

After it updated to 147.0.3 it says that it is not compatibile with miniversion 147.0.2 nor with maxiversion 147.0.2. It suggests re installing (done) so can now at least access Mozilla again but still says at varying times not compatible etc. It is Windows 10 Any suggestions?

Good day!!! I updated my browser today, and after that, everything I had in it was reset, from my account, open tabs (there were over 300 of them), passwords, themes, and everything else. If you don't know how to properly test your updates, then don't update your browser at all. Thanks to you, I lost a lot of information I needed. Thank you!!!!! I'm uninstalling your crappy software and switching to Edge or Chrome.

I admit I have a minimal machine for FF --- Win 7 pro, 2G ram but up to now it has managed---I just can't have too many large tabs open at one time. What gives with this install prob???

All I have is an older windows 7 dell laptop and firefox was working ok but then it said firefox must be updated by march 14 so i clicked on the update but it has been over 24 hours and the little circle is still going around with 0 results why

Greetings, Team. When Firefox does an Auto-update while starting, an error message arrives, " NSIS Error:

Error writing temporary file. Make sure your temp folder is valid.

OK " Please, where and what name does this 'temp folder' have?

How may I fix this Error?

Thank y'all in advance. Phil T. ps W10, Chkdsk OK, system appears OK.
