Hello,

I have the following error message......."The Application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sestrace.exe tool for more detail?

This error message pops up when I click on the Firefox icon. How do I correct this error message?

Thank you.

THis is such nonesense. I have no idea what the hell happened with creating a passkey. Of course the damed thing disappeared the moment I took the next step. I HAVE NO IDEA OF WHERE I AM IN THIS LUDICROUS PROCESS. It started with going to Google Docs where I am writing a novel and being told I had signed out of Synchronisation. Clicking on it produced this madness. HELP!

QR code for BankID loggin and KIVRA (in Sweden) is not visibel when I use latest version (157) of Firefox. When I use Firefox version 152 is it working. I have a mac OS version 10.15.8. What could be the problem?

Stop with the codes since I am logged in on both devices. Used Firefox for years and years. You are about to lose a loyal client I think I've put in codes/ passwords in 4 different places just to sync my laptop and phone.

I have always sent myself puzzles from the website thejigsawpuzzles.com to work later, keeping a file. The last few days I can no longer open them from my gmail, instead "server not found" appears. I no doubt did something but don't recall changing anything. I would appreciate any help you can give me. Thank you and have a good day.

MacOS Tahoe 26.7.1 Firefox Ver 157.0 My download preferences are ignored and downloads go directly to download folder without asking. All downloads have a .part extension even after download is complete. I tried trouble shooting mode and then added a new profile but the problem happens in all instances.

I am experiencing an issue where pages occasionally get stuck loading in Firefox.

Every now and then when I refresh a page (most notably on sites like x.com and gg.deals) a continuous loading spinner remains on the screen, making it look as the page hasn't finished loading, even though all the content has actually loaded in the background.

Whenever I refresh using Ctrl + Shift + R, this problem never occurs. So far, I have tried a full reinstallation of Firefox (including deleting all profile files) and testing on a mobile hotspot, but the problem still occurs on a completely clean installation and a different network.

I updated my Microsoft office to the latest office 365 desktop version. The install changed something, and any link in an e-mail now gets sent to Edge, rather than Firefox. I checked all the file extensions and made sure they all point to Firefox, but the problem is still there. Any suggestions for what to try next?

Hi. This is more of a bug report than a question, but after new update our company got a big problem: we print from firefox, but we had it set up so as we open the PDF document it would open directly into Adobe Reader (and then print). After update this is no longer available, altough the settings say clearly "open with Adobe/windows application". Is there a possible solution? Thanks for the answer
