Firefox Community Forum

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?

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?

So I guess my Firefox update to ver. 147 from 146 by its auto update feature, but I realized all the past personal data (ie, history, cookies, passwords, profile, etc) was gone.

I have Mozilla Account (I think it's the same as Firefox Account back in the old days), so my personal data is now retrieved from some device as far as possible, but I lost local personal settings like Shortcuts on the main page on my laptop,p which is the main device to do everything.

I can't help what happened to me, and I will rebuild what I used to be on that day, but I am curious if it's just me, or there is some logic to cause this data loss.

В России блокируют Firefox, по этому авто обновления не устанавливаются, я бы хотел получить ip и url серверов от куда скачиваются обновления. Это поможет обойти блокировку и восстановить работу firefox в России

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.

at present it is 32bit Llnux Firefox ChaletOS. It appears it wants 64bit Linux but every time it only allows me access to 32bit version which tells me is out of date. What is happening?

Since I upgraded from FF128-esr to FF140-esr I always get the "Firefox is being updated by another instance" This is really driving me crazy, as I checked / did / .... everything (and even more) I found on the internet related to that.

Nothing helps !

Creating and using a new default profile didn't help

Finally I ended up uninstalling FF completely (making sure no -zero- leftovers remained in ProgramFiles, AppData a.s.o.), and reinstalled FF140.7.0-esr freshly. After installation I started FF immediately with the created default profile (only existing one) --> SAME THING : "Firefox is being updated by another instance"

And this is really a FF140 thing, when I go back to FF128, on the same computer, same profiles, ...., the problem is gone.

I would like to know in detail what checks are really done by FF to decide to give that "Firefox is being updated by another instance"

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.

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.

Hello, I am still running an old WIn 7 media center because I have applications I need that are no longer supported elsewhere. Firefox ESR has been working just fine up until the most recent update - which repeatedly fails to install each time I start Firefox. Is there a location where this update resides? If so may I know this location and procedure to eliminate this errant update? Thanks!

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?

Mozilla support articles frequently state that Firefox does not use popups for browser updates. However, I periodically receive popups from the toolbar stating that Firefox couldn't update automatically. The attached picture is an example from the web but looks just like the popups I receive. The issue typically either resolves itself or I download from the Firefox website and reinstall. In a rush/moment of weakness, I recently clicked the link in the popup. It took me directly to the Firefox website where I regrettably downloaded and updated the browser. I've since run multiple Norton and Malwarebytes scans, which have found no issues. It may be a difference in the definition of popups (from the toolbar vs within a browser page)... Is this a legitimate update message from Firefox? If it is not, are there any other steps I should take (e.g., reinstall Firefox)? I appreciate your help!

Greetings Ya'll,

Early this morning as I went to use the Firefox browser, on My Desktop, I got an update, & then firefox opened, somewhat.

The homepage did not fill in with favorites, suggestions, etc, and in fact all that did load was the Search bar, but not one of my usual website buttons. The "edit", "help", etc. buttons at the upper left hand corner did load, but that is all.

Not one of the buttons work, nor can I close out the Firefox page, by tapping the "X" in the upper right hand corner.

The only way that I could close out the "Firefox Page" was by going through the "Control/Alt/Delete" & then "Signing Out", which would initiate a "Re-start". Once I signed in, I could return to the Desktop, where everything works.

I use Firefox as my Browser on my Android phone, & at this moment, I've not had any problems using Firefox on my Cell Phone.

The only way that I could get to the Mozilla Website was by using the Microsoft Edge Browser, which is not giving me any problems as far as accessing the Internet!

How can I correct this problem, & go back to the Firefox Browser?
