wish sending a question or replying to the email was easy but even that is b/s also this deny person claims bug fixed but obviously not

I have just started a new job and installed the Firefox browser on my PC (W11) as part of setting up my new workstation. The application works fine until I get a message that Firefox needs to install an update, 'please close it or it will close automatically in one hour'. After the update I get a message that the update is complete and you can restart the application, but the application no longer works; the icon on the application list no longer works 'The item firefox.exe that this shortcut refers to has been changed or moved'. After re-installing Firefox it works OK again, but the process repeats. Although I have managed to succesfully update a new installation on two occasions, after a few days the process repeats and I need to re-install again.

I’ve been using version 68.12.0 for a long time and now want to update to a newer version. Since I have many important tabs saved, I’d prefer not to uninstall and reinstall the app to perform the update. However, when I tried updating to versions like 80.1.2 or 110.0.1 from the Google Play Store or GitHub, the installation failed, and my phone displayed an "App not installed" error.

Could you advise which version I should install to successfully upgrade from 68.12.0? Alternatively, if there’s a way to export or back up the tabs in this version, that would also solve my problem—though I haven’t found a method to do so for this specific version.

Windows 11 Pro on Lenovo ThinkCentre. I switched to ESR a while back, when the regular and ESR versions coincided. All updates since then have worked fine, until now.

When I allow Firefox to update to 140.3.1esr from 128.14.0esr, then the Firefox browser no longer works at all. It comes up, but entering a URL (by typing or bookmark) does nothing and goes nowhere, so I can't use the internet at all.

I had to use Macrium Reflect to restore my system drive to an earlier time to get back on the internet, using version 128.14.0esr, which lost some recent bookmarks, etc. I have tried this twice, with the same result.

Now, a couple of sites no longer work because they say the browser isn't current.

What can I do about this? I hope I don't have to switch to another browser, because there are Firefox extensions I use all the time. However, I can't use a non-updatable browser indefinitely, because more sites won't work.

Can I fix this?

Thanks for your help, AnneF

Hello,

Today I updated to Firefox 143.0.3. When done (most of?) my add-ons were gone, in particular all my add blockers, facebook container, etc. Also, my search engine defaulted to Google (yikes!)from Duck Duck etc. I am very specific about trying to block all ads, trackers, etc and avoiding all Google products. Other things stayed the same like cookies preferences.

Is this done by design? Is there a file somewhere that still has all my add-on info, that I can restore.

I really would give up on browsing if I am forced to see ads all the time.

Thank you! Petrus Martens

HERE'S HOW I SOLVED THIS "SECURE CONNECTION FAILED" ISSUE:

Kept getting this error when attempting to update Firefox; didn't matter which browser I used; went through the forum postings and tried every this-and-that-and-this-and-that posted there; didn't work; finally --

i opened a $10.00 30-day hotspot account with Xfinity, and the download worked perfectly.

PROBLEM SOLVED.

Presently 142.0.1 (64-bit) installed; previous updates/downloads had no problems.

Now, however, going to https://www.firefox.com/en-US/?utm_campaign=SET_DEFAULT_BROWSER and attempt a download results in this (image).

Any solution to this?

Thank you.
