Firefox Support Forum

I use different extensions and have been experiencing the same problem intermittently for the second year in a row. For example, I use the Highlight This extension and I need to enter data in languages other than English. The problem is that if I start switching (win + space) layout, the data gets erased (because popup close). Other extensions circumvent this problem by creating a separate page (uBlock), but many do not provide it.

This issue was already posted here without results https://support.mozilla.org/en-US/questions/1291870

I just need a way to rearrange tool bars, and in particular, move the address bar to the bottom.

I am using: Name Firefox Version 91.8.0esr Build ID 20220330151638 Distribution ID User Agent Mozilla/5.0 (X11; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0 OS Linux 5.10.0-13-amd64 #1 SMP Debian 5.10.106-1 (2022-03-17) Debian 11 with Xfce 4.16

Whenever Firefox tries to sync, which is naturally happening on startup, it crashes with no error messages. I ran Firefox in safe mode by entering the command firefox -safe-mode and the same thing as before happened, but before it crashed, Firefox wrote Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Segmentation fault in the console, and then exited to the command prompt. Help!?

Often when browsing I find that when i want to use spacebar it does something i don't want it to do, which is advance the page downwards, like the "page down" button. I'd like to change that to something else, like maybe the page down key. Thanks.

I downloaded the latest Firefox to my Linux and got this error message: W: Download is performed unsandboxed as root as file ......etc. There's more, but can you tell me what happened and if I need to worry? I haven't had any trouble using Firefox since the update. I've attached a screen shot of the whole message.

I appreciate any help.

On certain websites I notices I have 'unknown errors' when trying to log in.

Usually this is remedied by either using Chrome or clearing cookies and the cache.

Both of there are inconvenient and result in a great deal of wasted time.

The usual response by these websites is "get Mozilla to fix this".

I'm getting sick of this.

I don't want to switch to Chrome but I will have to if this persists.

Hi, I recently had to upgrade my Linux system and Firefox along with it. I am trying to find my bookmark properties or description or comment field with important information that is not kept anywhere else. I found a couple old questions that I thought might be related to this but again they are old:

https://support.mozilla.org/en-US/questions/1233031 https://support.mozilla.org/en-US/questions/1232448

So this is a new question as the others were locked. I tried doing what was listed in them to make a backup/export but looking at the html only shows the book mark and no other fields related to the them. The bookmark-notes add-on is 4 years old so I don't know if that would help me get my stored information. This is causing me lots of problems. Please advise.

Firefox is having issues opening files in my tempdir directory. Opening a file directly, via File -> Open, there are no problems. But, when using either drag-and-drop or when trying to open an attached file from Thunderbird I will get something like the following:

File not found

Firefox can’t find the file at /tmp/pid-15374/etfExpectations_2022-04-22.pdf.

   Check the file name for capitalization or other typing errors.
   Check to see if the file was moved, renamed or deleted.

Firefox will only open in Safe mode, previously it was working but now it's not.

I have Ubuntu 22.04 Firefox version 99.0.1 (64-bit)

When I try to open it in command line, it's also only opening in safe mode but I do also get some error messages that I've included below.

So what does all this stuff below from the command line actually mean? And how do I fix it?

I am running WikiSpecies on Ubuntu Firefox 64-bit v. 98.0.2.

I used to be able to display a collection of unused files with the used ones but showing a red color indicating that the file was unused (because noone had entered anything other than the file name).

Now, however, ALL files in a directory (e. g., see https://species.wikimedia.org/wiki/Craspedophorus) are shown with the same color, whether they include additional implementation details or not.

Would it be possible for you to restore the "unused" color of empty files? It is bothersome for me to open EVERY file, empty or not, in a directory just to find that most or all of them never have been implemented. Adding a special color -- or other distinctive display -- to unimplemented files would save me a great deal of time.

I am attaching a picture of a typical unimplemented file.

This was going to be a question about Firefox being unable to display the file picker dialog, but I managed to find a solution that worked for me along the way. Since it was nowhere near the top of Google's results, I thought I'll share my solution in the hopes that this would help someone facing this same issue.

The hardware:

• Asus UM425IA Zenbook (AMD Ryzen 7 4700U CPU)

Worked in:

• Ubuntu 20.04 LTS
• Firefox provided by APT repository
• Xorg display server

Not working in:

• Ubuntu 22.04 LTS
• Firefox 99.0.1 provided by snap
• Wayland display server
• File picker worked briefly on fresh install, but something (not sure what) quickly breaks file picker functionality

The symptoms:

• Firefox stopped being able to open file picker dialogs
• Right clicking an image and selecting "Save Image As..." does nothing
• With forms that accept file upload (such as on this post question page "Add images (optional):"), clicking "Browse" does nothing
• File downloads work correctly when set to "Save files to ..." under Settings, but nothing happens when set to "Always ask you where to save files"
• No response to "Ctrl + O" open file shortcut

Similar questions and solutions:

• Fixed by reinstalling Firefox
• Fixed by resetting Firefox
• Fixed with a restart on a Mac
• Fixed by downgrading to Ubuntu 16.04

Things I tried that did not work:

• Disabling hardware acceleration
• Starting with add-ons disabled
• Troubleshoot mode
• Clearing startup cache
• Clearing cookies and site data
• Clearing history
• Refreshing Firefox
• Creating and using a new profile
• Deleting the `xulstore.json` file from the profile directory
• Toggling all permissions under Ubuntu Settings > Applications > Firefox to off and then back to on
• chmod 777 ~/Downloads
• Disabling native file picker "ui.allow_platform_file_picker = false"

And finally, what fixed it for me was to go into "about:config" and change "widget.use-xdg-desktop-portal.file-picker" from "2" to "0". Credit to this post that clued me in.

I really hope this saves someone else 2 days of hair pulling and I would appreciate advice from someone more knowledgeable than me on:

• Why this fixed the problem
• Whether I should be opening a bug report either against Firefox, or Ubuntu
• Whether I should also be changing "widget.use-xdg-desktop-portal.mime-handler" and "widget.use-xdg-desktop-portal.settings", both are currently set to "2"

When downloading files, FF opens a window to file manager. The window enables user to choose the download directory. But the window extends past the right side of the monitor, thus the "save" button is not displayed. Thus, files cannot be saved.

Hi,

I have a problem, which only seems to apply to Firefox. I am a developer for a site which uses LetsEncrypt certificate. When I access it via Firefox (and only Firefox), I get the error message as mentioned in the subject.

I tried to understand why this occurs. A quick Google just leads me to an issue with the Microsoft domain, and what I can understand was a Firefox bug.

Trying to figure out if it is a problem with Firefox, or a problem with the certificate. Any thoughts?

I'm running Firefox 99.0.1 on Ubuntu 22.04. Recently (I think since I updated to Ubuntu 22.04 about a week ago), Firefox has been refusing to show me file upload dialogs. When I click a button that's supposed to give me one, nothing happens.

This has been happening with: - The "attach files" button in Gmail - A file upload button on Gradescope (website for managing homework assignments) - File -> Open File... and Ctrl+O.

Dragging and dropping a file onto an email in Gmail does attach the file -- it's just that the button doesn't work.

I've tried restarting, and I've tried running Firefox in Troubleshoot Mode -- so far nothing has fixed the problem. What else should I do?

I just discovered this PPA thanks to OMG Ubuntu. But is this PPA official?

As per this issue I reported a while back, I was experiencing odd issue with automatic redirect to HTTPS for some private development sites.

I finally found a fix for the issue. The problem appears to be with DuckDuckGo Privacy Essentials Extension which apparently *may automatically redirect to the http site. In order to prevent this, I added my development sites to 'Unprotected Sites' and this prevented DuckDuckGo from doing the automatic redirect to https.

• - Odd thing is that I had multiple domains pointing to the same web instance and only one of the domains was having this issue with the DDG extension. Both were going to the same IP through a HTTP proxy. The proxy and web server were not the issue. This symptom points to an maybe an issue in Firefox....

In summary, be wary of odd redirects and the DuckDuckGo Privacy Essentials extension if you are doing web development work.

FF updated yesterday with the new Ubuntu 22.04 (Pop) update to 99.01. Since the update the volume control inputs are essentially disabled on all web sites, and they default to max - even when muted.

Example - youtube - all videos play full volume Reddit - even muted videos play full volume

The volume can now only be controlled by the system slider.

The same behavior does not occur in other browsers - e.g. Chromium, Opera, etc.

Can anyone assist?

Hello

I do not understand how firefox sync is supposed to work. I have a desktop and a laptop. The desktop is FF 85 on Linux Mint (I cannot get a later version due to some querk) The laptop is 99 on Windows 10 Both are signed in to sync but my bookmarks were scrambled so I signed out the laptop and cleared the profile, cleaned up the bookmarks in the desktop and to be safe I tried just syncing the tabs, not the bookmarks, by opening the fresh firefox on the laptop and signing in again. In the sidebar under my account icon I clicked "Synchronise now" and the open tabs from my desktop appeared in a list underneath, jumbled up. (I have 2 separate windows open on the desktop with different tabs in each, but this separation was not followed either, there didn’t seem to be any provision for syncing tabs in two separate windows)

But the row of tabs didn’t open, all I can do is open them one by one from the list on the right, this is a slow process as every time I click on a tab in the list the new page opens in the same single tab, not a new one, but the sidebar closes again.

Is this what’s supposed to happen? I was expecting the synced row of tabs to open automatically.

This feature would have been useful as my OS on the desktop, (Linux Mint) tends to crash and to have the on the laptop would be a good backup.

Incidentally the other way I try to back up the lost tabs is to select them all and bookmark them to a new folder which I call “backup” but it seems this doesn’t necessarily duplicate them, which I would prefer, so any of the open tabs that were previously bookmarked risk being removed from the original bookmarked folder, without my noticing, and I am therefore reluctant to delete the backup folder without checking that it doesn’t contain the only bookmark of a page.

When I came back to syncing the bookmarks, how do I avoid them getting scrambled again?
