Please explain the problem in detail. What happens? What are the exact error messages?

I've been using Firefox quite a while now and it's my default browser. Till now I've had near to none problems with it but since yesterday or so whenever I double tap to open any pdf file via Firefox, the print file window pops up from nowhere and has become quite annoying as I have to manually close it. I tried searching for a fix on the internet but found nothing. Does anyone have a solution to my problem?

Does this help? https://www.mozilla.org/en-US/firefox/98.0/releasenotes/ Firefox has a new optimized download flow . . . .

You can set this pref to false on the about:config page to prevent opening the download panel on each download.

• browser.download.alwaysOpenPanel = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
