Cannot get rented/paid Youtube or Netflix video to run. Message "! Sorry, there was an error licensing this video" pops up onYoutube screen every time when hitting play button. "Free" Youtube videos work just fine, paid content gets this message. Have firefox-9.5.0.2.ta.bz2, use Linux updated software. Followed all previous suggested Support, cannot seem to find fixes that included DRM, Safemode switch, etc. Thanks for previous help, still stuck... anymore ideas appreciated. Also, difference between running "normal and beta", please explain, and how to know "differences?"

I inadvertently (Stupidly!) deleted all web browsers on my spare computer. I re-installed Firefox on that computer but still cannot get web access. What can I do?

What is the minimum set of files that I can recreate a FF user profile from?

For example, the official docs say to backup/migrate a user profile by copying the whole directory, but the I'm not interested in the `Crash Reports/` directory, history or any session information.

Based on a post I saw some time ago about Thunderbird user profiles, I would expect that only a few files are actually needed (off the top of my head from the TB example, possibly `cert9.db`, `extensions.json` and `prefs.js`), but I can't find the post again now to double-check and I'm not sure how well it would apply to FF.

So, what files do I need to copy over to a new user profile to retain my:

1. extensions and their preferences
2. Firefox preferences
3. bookmarks

Hi...please help. Anytime I update anything on Firefox , I end up with a mess. All I did today was make Firefox my default browser. Now, I have lost all my emails and bookmarks. I need back at once please. My talents here are limited and do not understand cyber talk very well. Can someone explain in simple lay person terms how to fix. Thanks Gayle Pugh

I was using firefox by downloading it from the website and it was working fine. Then I try searching it in the MS Store to see if updates are possible from there or not and mistakenly downloaded it again. But I cannot see any desktop icon of Firefox other than the one I was previously using. If I go to the MS Store and try opening the app from there then a brand new Firefox opens which I simply cannot delete. I have even went to the Control Pannel to find out if there's another Firefox but there isn't. I am kinda worried as Firefox is my primary browser and I use it for literally every internet related activity. So please help me in uninstalling this second Firefox program which is unwanted here.

i just bought my pc with windows10, i installed windows11 ok, but started having problems keeping firefox as my default browser, msn outlook would pop up after i signed into msn calendar app, ended up resetting my computer and mistakenly uninstalled windows11 in the process, i seem to be compounding my problems as i go, im now confused and i need someone to connect to my computer and fix for me, if someone can do this i would be relieved, please let me know if anyone can help..

My old Linux computer died and I have removed the still good SSD from it. I have installed the latest Firefox on my new computer and would like to restore the bookmarks and other saved data to the new computer.

I am running Ubuntu 20.04, the old computer was on Ubuntu 18.04.

Can these things be restored, and if so what do I need to do?

to upgrade my firefox browser from 32 bit to 64 bit, I was following the mozilla instructions to download the 64 bit version, but then uninstall the 32 bit version before installing the 64 bit version. However, using the microsoft store to obtain the 64 bit version, it didn't just download it, it installed the 64 bit version. Now I have both. Should I merely remove 32 bit, and my profile file will be accessed to complete the set up of the 64 bit version? Don't want to loose bookmarks, passwords, etc. by removing 32 bit version.

This is the second time I've tried this, got sent back to sign in when I went to see what version of Firefox I'm using! I can't see the text of my mail in gmail inbox webpage using Firefox. I can see the whole message completely when I use the gmail inbox webpage using Edge. I have used gmail inbox with Firefox for years and this has only occurred today. I'm using windows 11, up to date and my Firefox is 97.0.1 (if I remember correctly, I'm not going to check again and have to start this process all over!) If I can't read my mail then is it Edge for me in the future?

This is not a request for help but a comment on the new version of Firefox. Today a new version of FF was installed on my computer and it wiped out ALL my passwords for EVERY account I own - personal and business. I am extremely pissed off because I have to reset all my passwords (which will take days)! For now on when you offer a new version of FF, warn the individual to back up their passwords and user names.

The question is am I going to keep using FF or just start fresh with another browser to avoid this headache in the future.

You have to up your game.

Since the update to FF 98.0 I cannot click on a .zip file & have it open to Windows File Explorer. It only allows me to download & save the .zip file and then extract the files from there. I have to click on dozens of these files per day for my job & would rather not have to save each .zip file & then extract the file contents. In Settings > Applications, .zip files are not on the list of file types or applications. Is there a way to add them to the list? Is there some other work-around? Thank you!
