On my Firefox (in Linux, at least), doing Ctrl+H toggles the History sidebar (opening it on the left side, or, hiding the sidebar completely).

How can I disable this?

Firefox 104.0.2 Linux Mint 20.3

I use Dashlane password manager which only half works in Firefox on my Samsung s22 Ultra. I have to manually open Dashlane copy a password and paste it into Firefox. At that point it would automatically fill. But that's not the real problem. I opened up the clipboard and found a whole collection of my passwords. How do I set up Firefox to clear the clipboard on exit?

I previously had a MetaMask extension on FireFox and it would open as usual. Several days ago, I opened Firefox and the MetaMask icon in the upper bar wasn't there. I tried to download it on the browser several times and eventually got the download and entered the seed phrase and, with some outside help, established the extension again and recovered my tokens. So all was good. But today I opened my FireFox and the MetaMask was missing again. Can you please help me find out why it is missing and how to keep that from happening again. Thank you

Currently I use Firefox and Brave Browser, I want to use only Firefox, but the lack of an option to create shortcuts like in Brave is what prevents me from doing that, these shortcuts are extremely useful and practical, but in Firefox the only way to do this is through links that will open in the browser, which is practically useless because I can create shortcut links within the browser itself. I also performed a procedure in the browser's advanced settings so that I could have this option, but it doesn't work either. So I was wondering if there is any other way to do this.

For some reason it seems like under windows 11 with a HDR display, websites like YouTube don't allow for HDR media playback. This is really disappointing and a major flaw as HDR media is definitely the future. And this has been working just fine in any chrome based browser for years now.

Is there any way to enable this?

Thanks for your time and help.

Today I stumbled on an issue that seems to have affected a number of users who care about profiles. The issue is articulated well here. It appears that a clean installation of Firefox results in the creation of two profiles, one called "default-release" and another "default" where "default-release" is the default. Ugh.

Can any user safely delete the "default" profile and rename the "default-release" profile to "default" to restore a simple, uncomplicated configuration? Why wouldn't Firefox do this by default?

I understand from question 1264072 that Firefox did this intentionally to support multiple installs and release channels, but why shouldn't the "default" profile be used by default? Surely a user who is not performing multiple installs or dealing with multiple release channels shouldn't have their profile names polluted by unaffected concerns.

Hello!

I'm having an issue with Netflix, i am unable to play anything there at all. It always shows a message saying "firefox is installing components needed to play the audio or video on this page" and refuses to load anything, showing an error, F7701-1003.

After some investigation, i found out that the issue is with Firefox not loading "Widevine Content Decryption Module provided by Google Inc.". I have seasrched and tried several troubleshooting processes, and was unable to find a solution. Refreshing, reinstalling, manually deleting the profile folder, all fails

Firefox Reader view is being defeated on some sites even though Firefox shows the Reader view icon. Example, on CNBC.com news pages clicking the Reader view icon replaces an article’s content with a CNBC page about their cookie policy, e.g. try using Reader view on https://www.cnbc.com/2022/08/26/iphone-gestures-and-hidden-menus.html Is there some way that Reader view can be made to work on these pages?

The (Download>save file as )function is completely F'ed up. Upgraded from Ubuntu 20.04 to 22.04 today. That included an updated firefox. Now when I download and save a file as function when I enter either a letter or number to rename the file the Search window pops up with options, or no options, that are available in the directory I'm saving to. The key or mouse focus is now in the Search box and not in the renaming the file box. That means in order to rename a file you have to switch back to the 'renaming the file' box fro the 'Search' box every time you enter a letter or number. Totally F'd up.

Hello, please how do I set up the browser so that the duplicate tab opens next to the one I want duplicated. Now the duplicated tab opens at the end of all the open tabs which is really annoying and not logical at all. I am using windows 10. Thanks

How do I open a local htm file on Firefox 14.1 on an Android 7 phone? The htm file is on the phone's SD card. When I enter either of the following in Firefox nothing happens: file:///sdcard/download/(file name).htm file:///storage/emulated/1/(file name).htm

Any help apreciated

Trying to use ProctorU with Firefox 104.0.2 on Windows 11 Home, and I am getting the following message : "Monitor Count : You may only use 1 monitor during your exam. Your monitor count could not be found". I searched for possible fixes, and someone mentioned removing fingerprinters, and possibly also remove cookies and tracking content from Firefox enforcement. I removed all 3 and that did not help. I also tried clearing cookies and site data and also cached web content, this did not help. Is there some other setting in Firefox that might be preventing the detection of the monitor count? Any suggestions on how to fix this issue?
