Reinstalled Firefox on Ubuntu 20 and signed back into my Firefox account and I don't have any of my passwords, bookmarks or extensions, I'm extremely upset - there's very important info I lost!

I recently did a fresh install of Firefox, and now picture-in-picture videos are defaulting always to the top-left corner of the screen and to not stay always on top; each time I open a video or refresh the page and re-start picture-in-picture it reverts to these defaults and I have to manually change it each time. Previously the default had been always on top and would show up in the location & at the size of my previous usage. I would like to adjust the default settings to make that happen again, but I can't find where to do that. I'd appreciate information on how to do this. Thank you!

I'm using Firefox Version 98.0.2 on Ubuntu 21.10 with Wayland and Gnome 40.4.0. I choose a larger cursor size from Ubuntu's Settings->Accessibility->Cursor Size. However, in Firefox the cursor always displayed in the smallest size.

For some reason, whenever I load a pdf from within Firefox, I get a new tab with the regular toolbar displayed on top of pdf files, but the document itself is completely blank (see attached screenshot). This issue just started today and I assume it was a result of an update, since I don't recall making any changes to my settings (I'm using Firefox 101.0.1 on Ubuntu 20.04).

I've tried opening multiple files from a variety of sites with the same result. All of them open fine using my system's pdf viewer, as well as from within Chromium. I've tried disabling my plugins, putting Firefox into safe mode and resetting all the handlers, to no avail. Any help would be much appreciated.

So I have been some issues with my Debian bookworm (Gnome bugged out) and changed to Sparky ( not a massive update I know, it's the same repo anyway) . Once Sparky Firefox upgraded to the latest version, I noticed some interesting behavior (tor running in the background and etc). I wasn't careful with playing gods with storage & cache, so had to again reinstall sparky. To my surprise my all passwords, bookmarks. add-ons are gone. I had just one account (was also using the dev browser for some time), so really it's awkward ad upsetting situation, any troubleshooting steps you can suggest?

Firefox allow to disable access to canvas for lowering fingerprinting, it's cool !

But as web developer : i like to ask this access before try to using it,

Something like :

1. Do you alllow canvas ? 2. Show the browser part 3. Wait for user answer 4. It's OK : download PDF done with canvass 5. It's not OK : shown an error to user.

To avoid such situation (see screencast)

I'd like to watch the episodes I missed of Suspect on Channel 4.

When attempting to do so, I get a 'Digital Rights Management (DRM) Not Enabled' message, even though it is enabled in Preferences!

Google Widevine plugin is also activated

Any ideas please?

TIA

Until recently, whenever I downloaded a file, the Firefox dialogue requesting the destination folder started out at the folder I last used to download a file from that web site. Now it appears to always start in the last used folder, independent of web site. Since I seldom download more than one file at a time from a given web site, this means I have to navigate the directory tree for every download, which makes the whole process take two or three times as long as it used to. Is there any way to restore the old behavior? My searches on the web have only turned up suggestions that are accompanied by responses that say "That didn't work." (Running 101.0.1 on Ubuntu 18.04, if that matters.)

I know there are add-ons that will let me script the download folder selection process, and I'll go that route if I must, but I'm hoping that my preferred browser behavior is still available - "just works" is preferable to "you can beat it into submission if you try hard enough".

I accident clicked delete download when from my downloads list in firefox and I can't find it anywhere on my computer? Does anyone now how I restore this file to save the time having to re download it? I am using Ubuntu.

Good afternoon. I just made a clean install of Ubuntu 22.04 in my system. I use Firefox, to navigate, study and download diverse things, including work files. When I tried to download those files in my google drive, it shows me the folder which I will use, everything right, but when I hit "Save", nothing happens. Do you know which is the problem? I can access drive from "files" from Ubuntu without problem, upload and download files... Thanks in advance.

For instance there is a site I use, which has a list of my posts, with buttons to delete the posts. I click the delete button, this opens an "Are you sure?" modal window, I click delete, the modal closes, I am on the same original list page with the same URL, but now I have another pseudo-page in my back button history that I have to go through.

If I do this with three more posts, I will have an additional three back button history dropdown entries to navigate back through.

When I exceed the number of entries shown in the dropdown, I have to keep clicking through the quasi-paginated list of duplicated back button history entries for the same exact page, to get back to the page I was on before ever going to the list page.

I have my web application built using angular v8.0. In one of the page, we construct a date field in the corresponding component.ts file as following.

data: new Date(modifiedAt).toLocaleDateString('en-US',
                          { weekday: 'long',
                             year: 'numeric', 
                             month: 'long',
                             day: 'numeric',
                             hour: '2-digit',
                             minute: '2-digit' }),

Here modifiedAt is variable of type Date. The data attribute is then passed to an HTML template in another component.ts file and using date pipe from angular framework, we format this value as shown in below code snippet to display it in UI.

<span class="table_data-wrapper" title="{{ data | date : 'dd LLLL yyyyy h:mm a' }}">
      {{ data | date : 'd LLLL yyyy h:mm a' }}
    </span>

Now in Firefox 101.0.1 when this page loads and tries to display this value, we are getting the following error in the browser console.

ERROR Error: InvalidPipeArgument: 'Unable to convert "Wednesday, April 13, 2022 at 09:08 PM" into a date' for pipe 'ht'.

The same piece of code with no change in the 2 code snippets mentioned above in bold works just fine with older versions of Firefox. For e.g. with v 100.0 it works just fine and renders the date value appropriately. This issue is causing other things to break on our application in production. Can some one please provide help on what might be going wrong here ?

Thanks, Maneesh Sharma

I was using Firefox and Owl (the addon).

I just upgraded to Fedora 36. I treid installing Owl and an alternative called "Dark Reader" and both cause a message stating they are corrupted.

I enabled dark mode in the browser. Google immediately changed to a dark background which I can more easily see. This site ignores the setting and is forcing me to work with very limited ivsion

I can barely make out the UI. I found what might be a solution at https://support.mozilla.org/en-US/questions/1356233 but after hours trying to read it I gave up and am wirting here.

It is very frustrating that other sites respond to firefox settings and your support site does not.

I KEEP GETTING MALWARE, TROJANS, VIRUSES IN THE .CACHE FOLDER OF FIREFOX FOR LINUX

IS THERE SOFTWARE OR ADD ON THAT WILL STOP THIS OR AN ANTIVIRUS ?

I USE LINUX MINT 20.3 CINNAMON 64 BIT

NO MATER WHAT WEBSITE I USE I GET THEM, AND COMODO FOR LINUX WILL NOT INSTALL CORECTLY.

In my settings it says my settings are being managed by my organisation. I am not in an organisation.

I have changed my password onm sync so I presume everything is signed out everywhere but the message persists. Who has unauthorised access to my account and how did they get it? How do I secure my account?

Unknown error code 100 Could not find the program '/snap/firefox/1154/usr/lib/firefox/firefox' Please send a full bug report at https://bugs.kde.org.
