the Adobe Acrobat extension stopped working. So I uninstalled it thinking I could find it on the list of add-ons and then reinstall it. However, apparently that's not the way this works. So I tried installing an upgraded version of Adobe Acrobat Pro DC, but the extension was not reinstalled in the process. I talked to the Adobe Acrobat help folks and they said that I have to uninstall and reinstall Firefox. I'm very worried about this because I have so many specific settings set up in Firefox and I don't want to lose any of those. Is there another workaround?

I have a dozen tabs opened in one window and would like to copy all of the url's and paste them into an email. I can do it one at a time but would rather do it all at once. Can it be done? Thanks

I have a new HP printer and I am using Firefox from a Windows 10 PC. I am plagued with Paper Mismatch errors when printing emails from Firefox. After a lot of trouble shooting, I have found that this problem seems to be confined to Firefox, as it does not happen when using other browsers, e.g. MS Edge. I have tried resetting all Firefox printer settings and the problem still happens when opening Firefox in Safe Mode.

The print job stops with the error message Paper Size Mismatch after the 1st page, and printing will not continue or even move on to the next job until the error is cancelled from the printer's control panel. This means I have to be working next to the printer and cannot print remotely.

In the printing dialogue box under Printing Preferences, the paper size shows Letter, whereas I am using A4 in the printer, and this is the mismatch causing the problem. I can change the paper size in Printing Preferences from Letter to A4, but I have to do this for every job seperately as the paper size setting always reverts to Letter. This is totally impracticable.

Regretably, I will have to stop using Firefox unless there is a solution. Can anyone help me to change the paper size setting to always default to A4, please? Thanks in anticipation.

Hi

I've just uninstalled Firefox as I somehow managed to have the beta version and the constant upgrades were driving me nuts. I now have 81.0 main version for Windows 10 64-bit. For many years I have kept my Profile folder on the D: drive for backup purposes. Having downgraded (by one version?) it won't let me use the old profile. Normally if I rebuild a PC or migrate, I edit %APPDATA%\Mozilla\Firefox\profiles.ini and point it to the profile on the D: drive but now I just get told to either create a new profile or exit.

How can I retrieve all my bookmarks, passwords and other preferences from my old profile?

Thanks John

Hi,

I just started getting an error message when I try to go to twitter: https://imgur.com/a/PfIHPh9

I've tried disabling my extensions without any luck and googling 'twitter' and then going to it that way works until I reload the page.

Incognito works fine so I'm not sure what the issue is

How do I prevent mail from certain websites going to Junk Mail? I have tried the online suggestions, but cannot resolve it. Some of the items I am advised to click on either don't exist, or I am too stupid to find them. I'm sure the answer must be simple. Help, please. Many thanks.

Confused old man.

Hi guys!

I'm a college student and my university uses Blackboard as a way to access our courses. Unfortunately, my Firefox has been breaking and not loading all of my courses. My university tech support is no help and they told me to contact Blackboard and Blackboard told me to use Google Chrome. I already installed Chrome so I can use it temporarily to do my coursework but I really don't want to use it permanently, I have my computer set up exactly how I like it and I prefer to use Firefox.

I think the problem started around when the September 22nd update for Firefox was automatically installed. Some things I've tried to fix the issue are: 1. Fresh install of Windows using the Razer Blade's recovery to factory default; 2. Update Windows to latest version (except the 2004 feature update, it causes my laptop to black screen on bootup); and 3. Fresh install of Firefox and changing my privacy settings to standard rather than the strict settings I usually use.

I didn't want to install an older version of Firefox because of all the warnings on the webpage, but I'm really not sure what else I can do. Has anyone else had this happen? Any fixes?

All the other apps in Office 365 work as normal but when I launch Sharepoint in a normal Firefox window I get the following error message:

• Sorry, something went wrong
• An error has occurred on the server.
• Technical Details
• Troubleshoot issues with Microsoft SharePoint Foundation.
• Correlation ID: xxxxxxxxxxxxxxxxxxxxxxxxxxxx
• Date and Time: xxxxxxxxxxxxxxxxx

Firefox is up to date (v81.0) and running on a modern up to date Win 10 Pro laptop, I've cleared all my browser history and rebooted but without success. The same web page works without problem in Edge and Chrome but in Firefox it will only work in a private window.

I have the option on the page openning my bank account to remember my customer number and DOB. I tick the option but it is never remembered . I suspect I have chosen an option in Firefox that causes this but I do not know which option. Barry Cross

when I try to open mozilla.org , the page opens for a short moment and then it crashes. I get the Information: The tab has just crashed. I use windows10, version 2004 (Build 19041.330) I suppose it's not a specific firefox-problem. When accessing the site with Crome, I get the error code: status_access_violation. Has anybody an idea? it would be great!

At first I thought it was an issue with "The New Facebook," since that appeared at the same time as the 81 update. But it's not. In fact, it happened on THIS page just now. Right after I typed "The New Facebook," all the text disappeared. Cursor stayed in the same spot. When I continued typing, the old text reappeared. On other pages, large black or white areas appear, seemingly at random. You can get rid of them by pulling the drawbar up or down.

I first noticed it when scrolling through photos on Facebook. In the first screenshot (attached) you can see the photo I was navigating AWAY from, with two small rectangles containing portions of the photo I was navigating TO. And the right-hand panel (with the text and description) is all from the photo I was navigating TO.

The second screenshot shows a typical Facebook page (or, what's SUPPOSED to be one) right after I typed a comment.

This problem does NOT show up on the new version of Microsoft Edge. (Not sure about the old Edge, I don't have it.)

My cache is empty, I'm on Windows 10 1909, all drivers are updated.

I am on Windows 10 and have not had trouble booting up Firefox to my home page, Dogpile, until the past few days. Every time I load Firefox, I get the captcha Are You a Robot? It is happening every time over the past few days. What is causing this? How can I get directly to my home website? Thank you very much for your help!

Hi, I've been having this issue for a few months now, and it can get really annoying. Like the title says, the right side of Firefox is cut off a little for me, both in fullscreen and windowed fullscreen. This problem occurs on all websites, and is only fixed when I restart in safe mode, though I don't think any extensions that I have could be causing this problem. Any ideas would be much appreciated.

Thanks!

I have a website that wont render correctly. It will not render most of the css on the firefox installation on my main computer. I have tried loading that website on multiple computers with the same version of firefox (signed into the same firefox account) and they all work. The website also works fine on Microsoft edge installed on my main computer.

The weird thing is, if I try to load that exact same website when it is downloaded to my computer, (from my hard drive) it works fine and looks perfect (same browser, exact same code).

I have tried to clear my data, and disable all extensions and plugins and that did not work.

Does anyone have any suggestions of ideas I can try before I reinstall the browser on my computer?

I am running Windows 10, Firefox x64 version 81
