Firefox Support Forum

The above question was answered .... Your attached Troubleshooting Information shows you have "AdBlocker Ultimate" and DuckDuckGo PE.

If you use extensions, always make sure such extensions do not block content.

I have cancelled all my extentions, and cleared the cache then, did a firefox restart. This has not fixed the problem. How can I work without an adblocker? I can print the emails in Chrome but not Firefox. How can I fix this issue?

HI, Yesterday (Sunday) i backup everything using the sync option. Restarted my computer with a fresh install of windows. Mow when i can to sync again, all of my bookmarks and add-ons etc have gone? Why? Please Help!!!!! Regards Dave

When I reply to emails, either reply, or reply all, I prefer to see all the email addresses from the email header that the original email was sent to. This is the default on most email systems I've used. I think it was the default on Firefox until recently.

Now, when I do a reply, or reply all, the message now starts with the original email, without the email headers. I understand some people may prefer that, but I definitely don't like it. It can be useful to see who the original email had been sent to, especially if there are errors in that list of people, or the people included are fewer or more than the previous email.

Note, if I forward the email, the email does contain the email addresses from the original email header.

This behaviour caused me some real grief when I realised some people had made a mistake when sending me an email recently.

Is there a setting to adjust this?

A website I use regularly has internal links that no longer work in regular mode. They used to work and still work in Troubleshooting Mode.

These links are imperative to using the webpage. I'm not sure what changed or why they work in troubleshoot mode, but I need to fix this right away. They also work on other browsers.

For several months now, my main Yahoo mail tab and also individual email tabs within Yahoo close automatically. It sometimes happens when I'm opening an attachment or switching to another Firefox tab but most of the time it happens randomly

I've turned on the setting in Firefox to get notified before closing a tab and also tried pinning the Yahoo tab but the glitch still happens. I'm not using private mode.

Hi, to be honest since many years when Firefox get launched i started to use it, until come Chrome but i wasnt too much happy, but to be honest and even when now i have a bran new pc Chrome take lots of resources that firefox doest. Even this way i wish to keep using firefox but i suggest for the next update in firefox add a new feature like the last added in Edge (sleeping tabs) this just put to sleep the unnused tabs to save resources, save ram.

Thanks.

Hi. Firefox is my main browser and I use it also on my business corporate laptop under Win64bit. Only recently each time Firefox needs to install an update, a window pops up asking for permission of the admin (and I am not the admin), so I have to call the IT dpt and ask an admin to log in and give its authorization. The IT team told me that it's not a problem of the corporate firewall and it's up to Mozilla to set the update process so as to avoid asking a high level authorization. This problem is becoming very annoying, as the Firefox updates are usually very frequent. Can you do something to fix it? Thanks, kind regards Fabrizio Venice, Italy

Yesterday I had Picture-In-Picture (shortened into pip for next mentions) working on youtube, then after one day, PIP no longer works on any of the websites, including youtube. I tried disabling and enabling pip, entering troubleshoot mode, and none of them worked. Not reinstalling because it will be annoying to log in everywhere I've had account at.

Any solution?

I'm finding videos on certain websites stop responding to mouse clicks, or the spacebar key (play/pause shortcut), soon after opening full-screen mode.

I ran the SEO Site Checkup flash test for one such site and it reported no Flash being used on the site. (https://seositecheckup.com/tools/flash-test)

Seems to be no problem when playing YouTube videos.

Not able to reproduce the problem in Google Chrome.

Steps to Reproduce: Copy picture from browser(Happens only when copying from Mozilla) and paste it into discord message window

Picture actually should attach only as one file

Happens not only to me https://www.reddit.com/r/discordapp/comments/x11iq3/comment/imbg35t/

I'm trying restrict usage of fingerprinting for my browser. I've already checked some articles and resources, for example this one: https://support.mozilla.org/en-US/kb/firefox-protection-against-fingerprinting

Currently my setup is like this: - I set "Enhanced Tracking Protection" to "strict" - I set "privacy.resistFingerprinting" to "true" - I'm using uBlock Origin

But still when I visit https://amiunique.org/fp I'm getting the information that I'm unique. The worst performance is amongst: Headers attributes:

• Content language: <0.01%

Javascript attributes:

• User agent - 0.49%
• Content language - 0.04%
• Canvas - Unique (this is weird because I'm even getting a notification about blocked canvas, maybe it is a quirk of this website)
• Screen height - 0.05%
• Screen available Height - 0.07%
• Media devices - Unique

Is it expected for Firefox to fail that test? By Firefox own marketing I expected that I'm protected from fingerprinting but in fact I'm not. And worst yet it isn't even turned on by default.

What can I do more to actually block fingerprinting? I tried Ghostery and Privacy Badger extensions but they didn't seem to help so I removed them.

After the November 7th update, I've gotten several websites that will fail to load. Ctrl-F5 does not help. Have attempted to use the websites in another browser and it works fine.

The Bookmarks Toolbar is showing up with a message to use it, even though I don't want to use it and have not added any bookmarks to it. This has shifted the actual screen down one line and messed up things I do that rely on screen positioning. Please turn it back off.

Hi, difficult to find this way to write you...

I reset my Mac and thought Firefox would keep all my bookmarks for when I would reinstall Firefox and synchronize all my bookmarks, like I always did. It was not necessary to export and to keep them, because I have never had problems before and I trusted Firefox.

Now this did not happen and I lost if not thousands of my bookmarks I have gather in years... I'm very disappointed, for the first time.

Do you have a cache or something or other solution so I can get my bookmarks back? Thanks.
