Diễn đàn hỗ trợ Firefox

i cannot print any web page from Firefox. The print option only offers me the option to save as PDF. Firefox is not detecting either my Brother laser printer or my Epson inkjet printer. if i use the print using system dialogue option fire fox shows a printer screen which has a simple entry of line prntr. If that is selected nothing at all happens. Clearly Firefox cannot detect my printers. If I save the web pages to a PDF file then open that file I can then get the normal system printing options and print the page. But all that does is clutter up my file system with files I will only ever use once. This proves the problem is clearly in Firefox and in its inability to detect system printers. I have tried all the suggestions from the help screens to no avail. Is there any other means of sorting this print problem.

I lost my tabs. Firefox has been opened and closed several times after losing tabs. I went here https://www.jeffersonscher.com/ffu/scrounger.html. I was able to find the file containing my lost tabs, it is sessionstore(1706800631216_9931f324-5558-4488-a36c-a5b3cb9e8c54_event_jsonlz4).json What do I do with this file now? Thank you.
