the original error was posted 2015 I had the same quite some times no in 2025/2026

"My Firefox is opening in Administrator mode, which prompts me to agree to allow Firefox to make changes to my PC every time I open it up. I read that I needed to go to Properties and deselect all my compatibility settings but this doesn't work. Any suggestions would be greatly appreciated?"

I purchased Mozilla VPN weeks ago and having problems installing it. Request requires elevation.

Seems I wasted my money if I can't install it

I have used Firefox for years. Have a backup computer that has Windows 10. It defaults to Bing. I hate Bing! VERY much want to use Firefox for Windows 10. Please, if you can, just email me a link to download Firefox that will work on Windows 10. That is all that I need. My two email addresses are: [edited] OR [edited from community support forum]. Either address will work (both are for same account). Thank you so much for your help! LOVE Firefox!

1. How to move mail between two different Macbooks with different OSX and different versions of Thunderbirds?

How do I move my email profiles (there are several) from an old Mac to a new one, when the old Mac can't be upgraded anymore and the Thunderbird versions don't match?

Old Macbook OSX Monteray 12.7.4 can not go any higher on OSX due to hardware not being compatible Thunderbird 140.5 Oesr 64 bit - don't know if it can be updated or not, but expect not. Minimizing run time as much as I can because the fan is going nuts and I think the battery is going - gets very hot.

I copied all the different profile folders from the Old Mac to an external drive. However, I don't think I can just plop them in to the new Profiles folder on the New Mac, given the Thunderbird versions and OSX version don't match.

New Macbook OSX Sonoma 14.1 Thunderbird 153.0.2 aarch64 Not updating to Tahoe yet because then I can't use my 2019 MS Office products - need to save up to update those first

All I need is e-mail - not calendars, contacts etc., although it might be nice to to have those Thanks in advance

2. How to .pdf old emails (With attachments) Also, the profiles folder is huge (219 GB), with multiple profiles and I want to save old emails (with attachments) into .pdf and appreciate advice on what .pdf converter/file converter would be best. It doesn't have to be free. It does need to respect my privacy.

Both Mozilla products spontaneusly disappeared from my computer. Firefox requested a reinstall, and all was recovered. Firefox completely disappeared, and I had to restore from backups. I am seriously worried. What is going on?

Dear Mozilla team, I have nothing to add I made a short summery to a guy who asked why his computer starts redumdebly with Gmail and it's specially to him my question is adressed to.
