I-Firefox Isithangami Sokwesekwa

When I go to a web page which is a PDF, the web page used to load as a PDF. Now there are 2 tabs, one is blank and has an address which refers to the PDF location, and the other is a PDF saved to the Temp folder (eg. file:///C:/Users/USER/AppData/Local/Temp/some_PDF.pdf)

My preference is: www.some_website/some_PDF.pdf

This is because I save the tabs, and the next time I use Firefox, the temporary PDF is not loaded anymore. As well, I prefer 1 tab instead of 2.

Where is the setting to adjust?

Why can't I use right click menu in Alert Dialog? I select the text in an alert dialog but when I press right click the menu will not show up. I works in Chrome. Why not in Firefox? Any way to have it work?

I've tried all the steps necessary to sync my mobile phone to my desktop. And nothing is working. Does anybody know what to do? My mobile bookmarks don't show up on my desktop and I have a lot of them. Any help would be appreciated. Thanks.

Hi! so I installed Kubuntu 20.10 after using it 'directly from the cd' for some time. since, all data would be lost every time i restart, i would keep a copy of a '.mozilla' file i would find in the system. Everytime i start the OS, i would first create a folder and copy paste it, so firefox would start right where i left it off. this worked, until i decided to make Kubuntu permanent. at first things were going good, but after sometime, my OS would stop recognizing my headphones and audio port completely. at first i blamed it on my OS and went about doing somethings here and there to adjust by. but looking back, i had installed some DRM to play some video on the net. so in a desperate fix, i replaced the current .mozilla file with a backup i had. the thing worked like a charm and my audio was fixed and everything was going ok, except for the occasional fixes so that my OS would channel the audio to the right output. that is, until the problem rise again! this time, i hadn't installed anything like i did previously, so i replaced the .mozilla file again and it worked! but i can't keep doing this and i had also faced the same problem in my windows, resulting my change in OS in the first place (I think its the same issue, because whatever i did didn't fix it and windows is more sophisticated that i wouldn't know). I don't know if this much info is too much or too less or that if i should post this here or in any other forums, but i would really appreciate it if i got a solution! Thankyou!
