Recently, I am unable to open PDF's on Firefox. When I go to another browser and access the same site (such as a bank) I am able to view the PDF. I have tried some of the suggestions regarding extensions etc, but nothing seems to work. Is there a solution? Thanks, SVS

PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR

This error occurs constantly on Firefox. I've had to go to Chrome to connect. I want to use Firefox, but not if it keeps doing this.

For the past several months, I've had increasingly worse graphical errors on Google Drive. At first it was only in a few documents, and now it's in every single document. These errors only occur on Firefox, no other browser. Text that I type is constantly blurry, oddly-sized, or oddly-spaced, with some letters touching while others have large gaps between them. I've also had some other small issues, like the document thinking that I'm two people and asking me if I want to see "the changes made my collaborators" when I'm the one currently typing (the documents aren't shared with anyone else, and there are never any changes beyond the ones I make), or showing my cursor highlighted with my name as if I were someone else watching myself type. It's made it more difficult for me to focus on work and I don't know what to do about it.

I've tried the following methods (most of them multiple times over the past months) to solve it, none of which worked: - Running the windows in safe mode - Uninstalling all add-ons and themes, clearing cookies and cache, and then restarting my computer - Uninstalling Firefox entirely, restarting my computer, then reinstalling it - Refreshing Firefox - Looking through pages like Firefox Task Manager and such (although the information there didn't really mean much to me, nothing looked out of the ordinary)

Does anyone have any ideas about what I can do about this? I was ignoring it for a while since it's still legible, but it's become really annoying, especially when it makes some words hard to read. Thanks in advance for the consideration. Here's a screenshot of a document with the weirdly-spaced, blurry text:

For some reason I looked into whether my Firefoxes are ever using HTTP/3 - turns out they aren't. I looked up how to get any kind of information on this, and saved networking logs. They indicate that the moment Firefox tries to send the first UDP packet for the HTTP/3 connection, it gets "ErrorAccordingToNSPR [in=-5987 out=80004005]", the connection fails, and the server is added to an exclusion list so that no further (futile) attempts at using HTTP/3 will be made (which makes reattempting a HTTP/3 connection by hand that much harder). The initial platform was Windows 11, with Firefox 98.0.2, but afterwards I reproduced the issue on another PC running Windows 10, and with a nightly version on Windows 11, which I also used to save some logs which I can publish, as they don't reveal the sites I visit (though I can always provide the logs from my everyday instance of Firefox, should you find the information insufficient).

I also confirmed that HTTP/3 works with Chromium on the very same system and network, and also with Firefox on another machine running Linux.

I want Protonmail as my default mail for Firefox. Windows 11 allows me to install Protonmail as an application. I cannot find or use that application in order to use my Protonmail email as my 'mailto' option in Firefox. Why does Firefox not allow this? Why can't Firefox find and suggest the Windows 11 Protonmail app in its list of suggestions under 'mailto' options?

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!

Any way to cast to chromecast with firefox?

It's annoying that I have to use Chrome or Edge to cast youtube to my TV.

Or use my phone. But it's charging atm. So very annoying my favorite browser can't do this simple thing. But all the other browsers can.

Firefox keeps disabling addons randomly, some of them are made by mozilla even. I am getting them from the official addon site so they shouldn't be illegitimate ones. Let me know what information about my install I can give to help.

OS version: windows 22000.593 Firefox version: 99.0.1 (64-bit)

Hi, I've been a Firefox user for many years and don't have the slidest idea of what password I used to setup the account. I read in the Firefox documentation that I could loose all my information if I change my email but that's exactly what I need to do. I currently use gmail and have switched to Outlook. Two questions, how do I change to Outlook without loosing bookmarks, etc. and can I import my gmail accounts into Outlook. Thank you in advance. PS, I created a Recovery Key

when i pull up a log in page firefox always wants to fill in my log in name. i went to the settings page and firefox says that i have no saved log ins. how do i clear my log in name or stop firefox from trying to fill it in for me.

Hello,

I noticed that a setting on the about:config page was removed: the "security.csp.enable" setting. I was using this setting to disable CSP to be able to load local JS scripts on some non-locally hosted sites, for debugging and development, work related purposes.

Was this setting really removed? Is there a way to disable CSP on Firefox on the latest version?

Thanks! Gabriel.

I like to clear the cache on a regular basis but then Facebook does not recognize my laptop and I have trouble logging back on. Is it possible to clear the cache for all but a select website? Thanks

I am trying to add my Android phone as a device to Firefox. I initially invoked the code scanner next to the search bar, but got a message saying that the code had to be scanned from within the Firefox app. So I installed the app and followed these instructions entitled "Connect Another Device".

• If you haven't already, install Firefox on your mobile device. • Open Firefox on your mobile device. • Open the menu, tap Settings and select Turn on Sync. • Scan this code:

There is no Turn on Sync option in the Settings menu. I have looked in every menu item that appears even remotely related to syncing with a QR code or adding a device and come up empty.

I found this exact issue in two existing questions, but neither of them had ever been answered, which makes me less than confident that mine will. If there is a Turn on Sync option in Settings, and I just overlooked it, please explain step-by-step where I can find it. If there really is no Turn on Sync option, please provide an alternate method of adding my Android phone.

Thanks.

my pc had friend so when i got a new one i lost all of my firefox data, how can i get all of it back so i was forced to start all over, i lost all my, bookmarks, tabs, history and saved passwords

I downloaded a large filed in my Firefox Browser and it took me 2 days to download the file but when it's almost done, it suddenly failed download. Can you help me resume the download? I think it stopped around 60 gig.

I had a Firefox account on my phone. I got hacked. So I uninstalled the Firefox app. I got the upgrade for Lookout and added that to my phone. I opened a new Firefox browser on my PC because I was tired of Google and I don't like Bing. I think you are still using my phone account. dawniegirl1973. lt has never been a primary or secondary email for phone or Pc. But you caught the last hacker! I would like an upgrade with Firefox on both PC and phone if I wouldn't have to pay for both devices. Would that cover both PC and phone? They are not linked, but they do share 2 emails and passwords. I also would like VPN, if that would secure my wifi. But I need a network that I can use for all my internet needs. I don't know what all VPN does. Please help me out. I don't know what to do anymore. It's all gotten so confusing. I'm tired of being hacked. Please advice. I trust, you, Firefox and I want you on both devices can we do this?

Hi Firefoxes! I updated to the latest and greatest 99.0.1, whenever i use the middle mouse button it opens every link in 2 tabs. Also when i middle mouse on a tab, 2 tabs are closed. Anyone came along this bug? Restarting FF and Windows did not help. Trying to get my notebook charged and check it on my macbook.

TYVM! Best regards, -John.

I cannot access my primary Firefox account, don't have a two-step authentication app configured for the account, can't find recovery codes, and don't have a logged-in device. In addition, I subscribe to premium services linked to the affected Firefox account, so I'm now unable to access them as well. To ask this question, I created a new Firefox account.

What should I do now? It seems I'm stuck paying for services I can no longer access. I can't even cancel the premium services since I can't access the affected Firefox account. How can I contact Mozilla Corp?
