Firefox Support Forum

Hello

I want to use extension xpi's from a shared external folder over multiple Linux profiles. So i examined the profile folder and found extensions.json. Though i can't find any documentation to it's keys online.

There's "rootURI:" with a "jar:file://path/to/extension.xpi!/", so i tried just replacing the path with the shared one. Though i observed that just makes firefox replace the path with the current one. So i examined further and found the "location:" key with the default value "app-profile". So my guess is, there's other values for other usecases, right?

So, in summary, what i need is:

• documentation to extensions.json keys or possible values to "location" key.
• if that isn't intended/doesn't work, how i can achieve my goal otherwise.

And please don't suggest the sync feature, that doesn't work for my usecase.

Issue summary: I lost over 100 sites listed in the Cookies and Site Data section when I simply removed a few websites in the Enhanced Tracking Protection section.

Under the Browser Privacy section, the two subheads, "Enhanced Tracking Protection" and "Cookies and Site Data" serve two distinct purposes—as I understand. Enhanced Tracking Protection will automatically add the URL of a webpage (that you currently have open) to the Enhanced Tracking Protection screen whenever you disable the shield in the search bar. This will turn off tracking for that website until turn you it back on. You can also manually add websites to the Enhanced Tracking Protection screen if you have mulitples to add. This whitelist will stay active until you delete them or click on the shield to turn it back on.

The Cookies and Site Data section further down, allows you to create a list of sites that you want to BLOCK, ALLOW FOR SESSION, or ALLOW cookies and site data to be used, and retained or not. This differs from the Enhanced Tracking Protection section.

Today, I wanted to delete one of the websites listed in the Enhanced Tracking Protection, and did so manually. But since there were only a couple listed (I rarely add to this screen), I simply clicked on "Remove All Websites" instead of "Remove Website." Unfortunately, when I went down to the Cookies and Site Data list (which I use all the time) to add a new URL today, my entire list was gone! I did not remove or enter anything in the Cookies and Site Data screen today, prior to using the Enhanced Tracking Protection screen.

As you can guess, I am sick because I had over 100 sites listed in the Cookies and Site Data section, and lost them all when I removed the few websites in the Enhanced Tracking Protection section. I don't know why or how this happened, but it is worth noting that I did just update Firefox this morning to vs 125.0.2 (from 124.0.2). My list is gone, but does anyone have a reason why it happened and is there a way to prevent that in the future? Or is it some kind of bug with the latest release or an earlier one. (I haven't opened the Enhanced Tracking Protection screen for a long time, so it could be from any past release.) Sorry I don't have more info than that. Any solutions would be appeciated.

Canvas is working on all other browsers normally, but when I try to login on firefox an error 403 message shows up at the two factor authentification step. I allowed popups already in this browser so that is not the issue.

I've been using the Firefox browser, and recently when downloading files with Firefox, sometimes it prompts: .part could not be saved, because the source file could not be read. # see image #1 I'm trying to download file to disk D. But the fail tips is download .part file to disk C. Maybe firefox is using some file cache policy which I don't know. I also checked both two location, my account have read/write access.

I can try to resume the download, and the download progress will increase, but about half a second later it will fail again. If the file is small and my internet speed is fast enough, after several attempts the file will eventually download successfully. # see image #2 I have tried using "private window" or enter "about:profiles" to create/use a new and clean profile, but the issue still persists. # see image #3 I tried using other download tools like "Internet Download Manager", and the download was successful. It's ok for use chrome to download the same file to same disk location. The problem recently emerged, it didn't exist before. At least a month ago, the same computer didn't have this issue. I'm not using parental controls.

Every once in a while, maybe once or twice a week, I'll press Cmd+L to highlight the address bar, type a URL for a new website, and press enter, and instead of going to that new website Firefox just reloads the current page. It seems that this happens exclusively when the current website is gmail.com. (I might be wrong) I can't remember it happening on any other website. This problem has been occurring for me for the past year at least. Any recommendations?

It has been observed that when a user uses the Firefox browser and tries to download a DDD file, the file format is .pdf instead of .ddd. In the devtools, it was observed that the content-type is text/plain in the response to the request. I changed the content-type to application/octet-stream, but the error still persists

For the last several days I cannot access my gmail on my PC with firefox. I keep getting an error message that says:

"We’re sorry, but your account is temporarily unavailable. We apologize for the inconvenience and suggest trying again in a few minutes. You can view the Google Workspace Status Dashboard for the current status of the service.

If the issue persists, please visit the Help Center »

Try Again Sign Out"

I keep trying, but to no avail. Gmail works with Chrome on my PC. How can I fix this?

I recently have gotten a message about manually updating Firefox on my Windows 11 system. Even after I updated, I then I started getting the same message and also "Failed to check for updates" in the Firefox "about" box and settings page.

I even went about uninstalling Firefox and reinstalling it while deleting the Firefox Program Files and user AppData directories. I also checked for a Windows Firewall entry for the program.

Is there something in another directory or registry setting I need to delete or change? Or does Firefox use a different program for updating that needs a firewall rule?

Thanks for any help.

Many thanks,

Due to repeated issues over a week, I uninstalled Firefox days ago. Tried to Reinstall it repeatedly on same device several times. It was working before..BUT it keeps showing its downloaded on Settings but Firefox download page keeps showing "DOWNLOAD" Tried several times. Not my computer. Nothing works to resolve it.. Windows 11..

Hello. I use youtube website as music player quite often (without premium) and play my favorite list of songs. Meantime, when Google started meddling with youtube due to their new offer as youtube premium I met two most annoying issues like "are You still watching" dialog and the behaviour where youtube just cleared "repeat list" function without my consent. Both issues was resolved with java scriplets I took from community.

Now I run into third issue but not sure how to diagnose it. If Firefox is in the background, or tab with youtube has no focus the playlists stops from time to time. The moment it stops is when next video should start playing. When browsing on different tab, I can see on Youtube tab that title of the video has changed (to the next video) and even the song started (for 1-2 seconds) then video pauses and word "playing" disappears from tab (normally there should be title on tab and "playing" word under title). It is not "are You still watching" dialog issue because if I move mouse cursor on youtube tab (even without setting focus on it) the player will continue - till next song.

The issue doesn't appear if youtube tab is active. I can't use developer tools in firefox because can't debugging website when tab of the site is not active (at least I don't know how). I tried to find solution with community but with no success. I allowed youtube to play video and sound always without exception in firefox preferences but it is not the solution.

Any tips?

I just bought a new laptop and downloaded Firefox as I have used it for years. Although I imported my passwords and they are correct it will not log in to sites I need for work. It isn't telling me I have the wrong pw or id, it just does nothing.

I have updated windows, I have uninstalled and reinstalled....I don't know what else to do...any suggestions?

thanks

This has been happening for months now, on multiple devices (I have tried at least 3 different devices), and on multiple networks.

I have read the articles in here, but they just want me to check network configuration which is exactly the same for all browsers.

If I restart firefox it starts working again.

How can I prevent it from breaking randomly? This is the only browser having issues, I'm almost positive is some bug and not a configuration thing, given that it happens under multiple circumstances and devices, while Edge and Chrome simply keep working just fine.

There is no consistent repro I can give, afaik it is just random, at some point Firefox just decides to stop working and I have to restart it. This disrupts my work and browsing activities as I can lose progress on input forms and similar actions.

something apparently got corrupted in firefox.. i tried running update and i keep getting failed to update.. i have refreshed.. i have uninstalled and reinstalled ...nothing. i am sure there is a folder or file somewhere that is corrupted and i cannnot find it. because even when i uninstall and reinstall fresh. all my bookmarks are there .. how to i start a TRUE NEW install??

Everything is gone….bookmarks, passwords, history on my desktop computer and I have no idea why. I opened Firefox and the home page was different and then noticed nothing was the same. I dl Firefox again, no help, same result. I do have my desktop synced to my iPad and laptop but I’m concerned they will import from the desktop and get wiped out. Is there a way to sync from the laptop to the desktop? I am at a complete loss on how to fix this. I do run a backup on this computer. Would that help? Restore point?

Many thanks,

Len

After just turning on my computer running Windows 10, I opened Firefox. I open 1 web site and noticed my computer showed a (16) prefix when loading Firefox. I opened the Task Manager and it showed that there were 15 instances of "firefox" running in the background. All showed a UAC Virtulization of "Disabled". But they also showed using 638.8MB of memory. I do not know whether these are necessary files that must run in the background or if the number of files indicates that my system has been hacked and someone else is in my system from outside. Any suggestions as to validity of these files running or how I might confirm that they should be running. I have noticed the number of excessive background files before but the number is never consistent which makes me fear I may have been hacked.

In all instances, when I click on a link to view a document on a website, rather than simply pop up to view, the document is downloaded and I am required to save it to my computer. Something in the Firefox settings is preventing the pop-up view from occurring. Not certain where to reset in order to correct this. Please advise

A couple of months ago, I suddenly lost all my saved bookmarks, plus the ones on my toolbar. Strange thing is, all the folders and sub-folders I created are still there, they're just all empty.

Can I get them back somehow? I've been collecting them for years so can't replace them all!
