I'm using 107.0.1 vers. At this link it states: https://support.mozilla.org/en-US/kb/view-pdf-files-firefox-or-choose-another-viewer#w_use-a-different-pdf-viewer-for-downloaded-pdf-files

Disable the built-in PDF viewer and use another viewer

You can also set a different third-party PDF viewer to handle PDF files, instead of Firefox’s built-in PDF viewer. To switch from using the built-in PDF viewer to another viewer: 1. Click the menu button and select . 2. In the panel, go down to the Applications section. (SO WHERE IN THE HELL IS THIS SECTION???) YOU CAN'T DO I never selected Mozilla to open any pdf and there's no where to opt out or change based on what all the troubleshooting tips say... All these tips must be located on a much older version of Firefox cause they ain't in my version OR they are hid under some dubious section... Pretty frustrating....when you want to use Adobe and can't cause I'm locked in under Firefox....don't know how that has happened unless it was done automatically under one of the many current upgrades that have been coming down over the last month.

I'm trying to install Mozilla VPN but it won't install. The error message is as follows: the installer encountered an error that caused the installation to fail.

I received an email saying that I had to sign in in order to keep my account. I did not click on the link provided since I thought it might be a scam. Was this a valid email? If so, is signing in now meet the requirement to keep my account?

Hello. I just have a general question. I have read about it a little but I get mixed info. Some say yes, some say no.... So, is it possible to get a virus or malware or any of that spyware stuff on mobile phones like you can on a computer? Particularly Android phones. They have all these anti-virus apps and stuff you can download saying they're designed specifically for Android mobile devices but then I have read articles that say that the Android operating system is not the same as, let's say, a Windows PC operating system so it's not possible to download spyware onto it. I'm just curious and appreciate any info. Thank you!!

I'm using Firefox 141.0 on OpenSuse Tumbleweed with KDE and Wayland. I'm using Firefox with two profiles: work and personal - which is (usually) awesome, until suddenly it's not.

Then, one or both profiles seem to become corrupted, and closing firefox, opening it, choosing either profile just hangs forever. My old tabs show up, but clicking on any tab, for any site, just hangs forever, and no page is ever loaded. Sometimes restarting helps, but sometimes not. Sometimes restarting 2 or 3 times and then suddenly it will work. But normally, I have to just delete all my profiles, and re-create them. Fortunately everything is synced with Firefox sync. Then everything will work wonderfully for a bit - although I have to re-login to everything.  :-(

Any ideas? This is a huge pain and productivity killer. I really love firefox, but this sucks.

I installed Firefox on my M4 Mac and it was in English, now it's in some other langue and I can't change it back. I deleted it, and reinstalled, same issue.

I cannot get it installed in English and have it remain in English. Please help.

I lost all my personal data on Firefox as soon as I changed the password and I did not know that you can lose everything that I had registered in the download box and the previous archive. Now I am very, very mentally disturbed and I do not feel safe and I am very sad about what happened to me. I am crying now. What should I do? My psyche is really broken due to the lack of information....

I cannot change the background image when my Firefox app opens on my MS Windows laptop. During set-up, the system had me select an image, but I want to change it as I find it distracting. Thanks!

Hello,

I really like using the "Shortcuts" (Top Sites) feature on the Firefox new tab page. However, there is one problem: Firefox automatically adds new shortcuts from recently visited sites.

I would like to keep only the shortcuts I manually pinned, without Firefox suggesting or adding new ones automatically. Currently, if I disable browser.newtabpage.activity-stream.feeds.topsites, all shortcuts disappear, and if I leave it enabled, Firefox keeps adding unwanted sites.

Could you please add an option to disable automatic shortcut suggestions while keeping only pinned shortcuts? This would make the feature much more convenient for users who prefer to manage their shortcuts manually.

Thank you!

I changed email adress 3 month ago and didn't update my Firefox profile. With only that adress registered (no secondary email) I cannot change to a new one or add secondary because a confirmation mail are sent to my old account, that are deleted. Are there any way to change email, add phone number or .... without access to the old email account?

I have set my account to "Don't delete any messages", because I frequently want to reread a deleted message in my Trash folder. However, when I go into my Trash folder to search for a deleted message, I am finding that messages older than a certain date have disappeared, although I've done nothing to permanently delete them. For example, today everything older than May 3 is gone. What can I do to prevent this?

thanks, CW

Every time I change my password or I try to change my password I get notifications double notifications actually one with an eight digit number one with the six digit number it's going to the same account but it's also going to another account in another town how do I stop this

I installed the 4 choice AI system and used it once and was impressed. At that very same site I wanted to highlite copy and paste but when I did the highlight was so faint as to be almost invisable . After some attempts and not wanting to lose that feature I deleted the AI via mouse right click. Realizing that was not the problem I have searched several times but cannot get any further thru settings and more tools to try to Reinstall that feature . Also the sparkle button never showed with the fisrt install. It originally appeared of its own accord . Will I get the choice again when I reboot .. ? hope you can help me thanks mike

- Had 3 windows open with numerous tabs and tab groups - Firefox sync was enabled, as well as a 2-3 plugins AFAIK - Version installed is latest as of this writing 139.0.4 - Initial crash caused by opening and quickly closing (IF that succeeded before crash) a onedrive share link - Cannot start firefox any more, also not in safe mode - the only thing that works is launching it with a fresh profile.

The report ID is bp-a8c824fc-a7fb-4290-a72b-b63160250620

Ideally I can resolve this without needing to refresh or start over with a new profile
