I want to be able to preview pdfs in firefox in a new tab without first downloading the file like it used to. But this version (99) of firefox won't allow me to do that. I tried selecting the "action" for pdfs in the applications section of settings to "open in firefox". What it does is preview the pdfs without downloading indeed but it previews it in the SAME tab which makes browsing more difficult. If I select "always ask", and then select "open with firefox" in the dialogue box, it opens the pdf to a new tab alright but it downloads the file FIRST. Is there a way around this please?

I have used LastPass extension on FF for years with no problems. About a week ago the icon disappeared from my extensions menu bar but would come back if I logged on to LP via the web. Today, it won't come on at all. I have FF ver. 99.0.1 64 bit on Windows 10. How do I fix this?

In the previous version I could run streaming videos from Paramount Plus, in the latest version I cannot run them. I have no problems running them on Microsoft Edge.

I get Error #111

How can I use Firefox?

I just installed Windows 10 and firefox and the video playback on those sites won't start. It works on youtube. Netflix and Curiosity stream works fine on Microsoft Edge but I want to use firefox. I did everithing of what Netflix sugested but videos won't play.

When using Google Meet, you are given the option to share your screen — either the entire screen, or a specific Firefox window.

I've noticed, however, that no matter what Firefox window is used, if you access an extension that creates a pop-up dialog, such as the Container selection button from Conex, the uBlock origin settings popup for each webpage, or a password manager pop-up such as Bitwarden, those popups will appear on the shared window, even if you decide to do this from another Firefox window altogether.

This is a major security concern for me, as I've had circumstances where the password entry window for Bitwarden will appear on any window, even if I open the extension pop-up from a window not being shared to Google Meet. I'm not sure where to submit this issue, so I'm starting from the Mozilla support page and going from there. Would appreciate anyone's help on getting this issue resolved. Thank you.

IT'S MAKING ME CRAZY - so bad that I've even tried MS Edge! Ewwww.... I read in the HELP files and online that I should be able to change the config to 1/1 after unchecking option to let Firefox control things in my settings. However, it does not pop up the change config box - and, I later read that it is not available any longer. This is killing me! Thank you for helping!

I subscribe to the Times.co.uk but past few days am unable to navigate on the website eg if I press 'show more on the web page' nothing happens. `It does work however if I access using my Safari browser, so clearly not a 'Times' issue

Hi Firefox community, whenever I hit "space key" while I type, then it scrolls downwards which I annoys me. This happened at "Otranscribe" website where I was typing and this thing happened. Please tell me how can I stop the scrolling when hitting space key?

Firefox now needs to be clicked on twice before starting. In addition is not reopening previous windows and tabs on startup although this option selected in settings. Is this related to a new version? Thank you!

I'm getting a blank/black screen when I try to signup for Disney Bundle....

What's going on...my settings? Which one/s...

Well, the subject should be self-explanatory. But i need help in creating a Firefox account. Keep in mind that I am not eligible for Google Play because I use a PC.

I have searched for this answer and can't find it, so I am hoping that it isn't here already and I just can't find it because of the way I am asking in the search box.......I would like to unsubscribe from an e-mail newsletter I am getting, but there is no "Unsubscribe" link at the bottom of the e-mail like there is on most of them I do receive. Is there a way in the Moz://a web site that this can be done? I am using a "mask" e-mail address and have done an unsubscribe with a different e-mail newsletter, but this one, I am not able to do just a simple "Unsubscribe".
